This is very serious first proposal.

As a professional mechanical engineer I have worked on high quality steel tubes (nuclear submarines) before. The immediate thing that sticks out to me in this proposal are the tight mechanical tolerances that have to be maintained. Talking about tens of thousandths of an inch tolerances on a 10' diameter tube is not to be dismissed lightly. That is going to be tough to maintain - especially with welding heat distortion. I would image the tubes will be joined with automated friction stir welding or something similiar, but that will still require a fair amount of post weld machining which has its own pitfalls. Not to mention simple thermal expansion and contraction as the temperature changes could change the circularity and inner diameter.

I would be more interested to see a tolerance stack up of those considerations than an FEA model of the concrete pylons. I can gaurentee that we can build concrete pylons capable of holding up a steel tube, that is done all over the country dozens of different uses cases. But can we build a multi-hundred mile long steel tube to the required tolerances?

I would be inclined to trade off efficiency for manufacturability. I.e. maybe a higher internal pressure or larger diameter to make it less sensitive. There should be plenty of power from the solar panels so it doesn't have to be perfectly efficient.

I'm also surprised that the I-5 plan is cheaper than buying private land. I may be naive here, but the pylons really do take away most of the objections from farmers and installing tubes over farmland has to be a lot cheaper than doing construction above a highway. I just look at boondoggle that was the SkyTrain in NYC (tram running over a highway out to JFK airport) and wonder if that is a great option.

"In the case of the Hyperloop, Musk started focusing on public transportation after he grew disenchanted with the plans for Californias high-speed rail system."

And who says that big government stifles entrepreneurial innovation?

If ALL Musk does with the Hyperloop announcement is shed more light on the potential debacle that is to be our $70b+ high-speed rail in California, we owe him a debt of gratitude.

I am intrigued, but not overwhelmed. Many of his reasons why his hyperloop is superior to high speed rail are not specific to the hyperloop. For example, you can put railway tracks up on pylons, too, with very little impact on the ground. It is common to do this in urban areas, but it is rarely done in rural areas because it is flat out cheaper to put it on the ground. I don't believe that an experimental tube is going to be somehow magically cheaper and easier to route and build than train tracks.

Now, I am not trying to defend California's HSR, specifically. I agree with Musk that it appears to be very poorly done. However, the answer, to my mind, is to do it properly rather than propose a wild experiment with hand-wavy arguments as to why it would be politically easier to do. Do you really think the special interests that are making HSR so difficult and expensive would say, "Oh, do whatever you like with your tube."?

Now, in an attempt to end on a positive note, I do like his proposal as a possible next step beyond HSR. Rail can go up to 350km/h currently (perhaps more in the future--why wouldn't California design with this goal in mind?), but Musk's hyperloop is proposed up to ~1000km/hr. It is definitely an idea worth exploring, but I think it falls far short as a serious alternative to the current high speed rail plans.

Reading the entire PDF is highly recommended; it contains a surprising amount of answers already (including many to comments below).

I think, if anything, safety aspects haven't been sufficiently explored in the pdf. I'm quite happy to believe it's safer than other modes of transport, but I wouldn't be too quick to overstate it. Also, if anyone can explain what "Tubes located on pylons would limit access to the critical elements of the system." is meant to mean in 4.5.6 I'd be grateful...

Adding a compressor fan to actively transfer air from the front to the rear of the pod while simultaneously serving as an air cushion to support the vehicle is simple, elegant and absolutely brilliant!

An ingenious solution appears so obvious in hindsight that it leads you to ask "why didn't I think of that?" While being subtle enough to confound all those who came before.

I have been following the developments of the ET3 Consortium for the past year. I have read virtually all the technical literature available online on the topic of alternative high-speed transportation systems going back as far as the RAND paper and even reading related patents from much earlier.

Looking at the genius of Elon Musk's insight is both inspiring ang greatly humbling - but mostly inspiring. Holy awesome! I would love to see this innovation take root. It could be the perfect elixer to our stagnant economic malaise.

Well done Mr. Musk!

I am skeptical of the proposed cost were someone to actually build this. Sure, the cost of materials, labor, engineering, etc. is probably accurate, but something like this has never been built before. What about the cost of research and testing? Not to mention there doesn't currently exist an industry of contractors to build most of the parts of this system, which is not true in the case of traditional high speed rails. Citing the cost to build something like the Hyperloop as the entire cost of developing it seems a bit disingenuous.

Not that it still wouldn't be comparable to the cost of a high speed rail system.

stevep98 5 days ago 0 replies      
A couple of points I would like to make:

* Structural requirements

The hyperloop has much less structural requirements than a traditional train. The reason is that its cars are separated, so it is 'less dense'. If a train goes over an overpass, the overpass has to be engineered to carry the weight of the rail and the train, whereas the hyperloop only has to handle the weight of the tube (30m between pylons at about 8 tons/m is 240 tons plus the negligible weight of the capsule).

The upshot of this is that the pylons can be much less invasive on the real-estate requirements. This is important because now you have more choices with regards to routes, which leads to less curvature and higher speeds. Looking at it from the reverse angle, High Speed Rail design suffered because the massive real-estate requirements imposed such a burden that route choices were compromised, and thus the projected travel time was lengthened.

* Tube manufacture.

It occurs to me that there already exists expertise in manufacturing elevated, highly reliable large diameter steel tubes hundreds of miles long. Oil pipelines. Moreover, these companies perhaps would be interested in diversifying their business away from oil.

* Development

High Speed Rail has issues, but they are political and financial, not technological. We're really just buying the technology from other countries. Much of the cost and the incredibly lengthy construction time for HSR is coming from building overpasses and the foundations for the rail, so far as I can tell.

But hyperloop is something that requires some development. This is a good thing because investors can sell that technology and get some return. It's difficult to attract private funding for HSR, but I can definitely see someone stepping forward to fund the development of the technology.

Pretty much once someone builds the hyperloop demonstration system, you'll know if you have a winner on your hands, but with HSR, you don't know if you'll be successful until the whole thing is built (and with a 2:30 travel time LA->SF, it's not going to be a slam dunk against air).

There are plenty opposed to HSR, but I see very few alternative solutions being proposed. This might be something those opposed to HSR jump onto, and it might get a lot of support quickly.

I love this concept!

My main concern is the air-bearing suspension system. Barring very high flow rates, the fly-height of an air-bearing system is very small. Some systems[1] fly at 5 microns, for instance. That being the case, any sort of particulate or imperfections in the tube will cause the air-bearing to 'land' with a large amount of friction. Perhaps this is alright if you're already going 700mph, but it would reduce the overall coasting efficiency of the system.

The engineer in me sees this as the most important design consideration of the project.

As an aside, I would like to see trade studies done on filling the tube with other gasses whose speed of sound is much higher than air's, allowing the capsules to travel even faster before shocks begin to form.

http://stopandmove.blogspot.fr/2013/08/hyperloop-proposal-ba...

The project also doesn't even attempt to price the connection into LA or SF. That's where the high costs are.

Amusingly enough, the California HSR budget for the Central Valley is under $10 billion. Ie, in the same ball-park as this proposal. The reason the HSR project is going to cost $60 billion is because it has to face an uncomfortable truth; actually getting to LA and SF is expensive. Very expensive.

Is Elon Musk's s mega-announcement really just a last-ditch attempt to sabotage the California High Speed Rail (HSR) project, rather than a serious proposal to revolution travel? Something smells very fishy.

The motive is clearly there.

The main reason why air travel continues to be the most practical, cost-effective means of high-speed transport is that the politics involved in connecting two points with a transit system are enough to make you lose faith in humanity.

Take for instance, the DC metro system. There is an expansion underway to extend the system west to Dulles Airport, about 30 miles or so from downtown DC. A huge project, no doubt, but it is about ten years behind schedule. What was a seemingly great idea (mass transit to a major airport and outlying regions of DC) was almost ruined by all the fighting.

This is for a project spanning 30 miles. Imagine the politics and fighting that occurs between politicians, contractors, lobbyists, and residents on a public works project that spans hundreds of miles between two of the most populous cities in the world.

A project this ambitious is only well-suited for a small, independent group of like-minded people, which unfortunately will never be possible with all the interests involved.

Wow, 300 comments in 2 hours--this is reaching the limits of readability. My first thought is that this release of Hyperloop details is like the geek's version of the Breaking Bad season premiere that is being so talked about in the US (didn't see it myself).

First of all, I think it's genius how nobody saw this solution coming, despite all the speculation. Put the air compressor on the pod, and use Tesla's battery technology to power it. Seems evident in hindsight.

My biggest gripe is the non-inherent safety and thus the security issues. The evacuated tube is a real issue in my mind, and saying it will be re-pressurized in case of an accident seems dubious. Yes, like a modern jet, but planes can descend to 15,000 and people live. Also, planes don't fly at 150,000 feet (the pressure equivalent in the tube) and there may be other biological hazards other than breathing. But mainly, the vehicles are subject to the same exterior threats as airplanes, so security will need to be similar. In addition the tubes are also a target of threats, which is less of an issue with trains and not an issue with planes.

Someone needs to convince Musk to build this on the east coast of Australia; linking Brisbane-Sydney-Canberra-Melbourne. The Sydney-Melbourne air corridor is one of the busiest in the world (6,795,000 passengers in 2007, vs 6,306,638 for LA-SF in 2009 [1]). We recently had a feasibility study into HSR along the east coast (a condition of Greens support of the current Labor minority government) but it suggested that such a project would be ridiculously expensive and take upwards of 30 years to complete (some say the study was doomed to fail and the numbers are wrong).

The geography is probably less favourable for Hyperloop in the eastern Australia context (e.g. Sydney is in a basin bordered by low mountains north, south and west), whereas the route it would follow in California is mostly flat?

I hate to be a party pooper, but I see some economic issues.

My takeaway is that while the 7 billion fixed costs will be low, the operating costs are going to be huge.

Battery packs and solar cells will need replacement. Large maintenance teams will be needed with immediate response times to fix issues such as complete seal blowouts, etc.

I think the first few years will be great! But in my opinion maintaining this system over the long term will be very, very expensive compared to slower rail.

I'm still optimistic that most of these and other issues will be worked out in the long term.

As someone who gets claustrophobic on planes - I have to fight the panic every time I fly, the dread that fills me at the thought of a service/system malfunction, while halfway between LA and SF, what happens then?

I'm reminded of this water slide at the Gold Coast's Wet and Wild - you end up going upside down - but in order to attain the velocity required to make the loop, you need to be dropped from a particular height, only some people don't make it - so they have a single access point into the tube where people who haven't made it, can get out, but I'm sure it wouldn't be a fun experience, so I opted for not going on that slide, even though my kids were pleading with me to do it. No thanks.

Some interesting tidbits:

    The total trip time is approximately half an hour, with capsules     departing as often as every 30 seconds from each terminal and carrying 28    people each. This gives a total of 7.4 million people each way that can be     transported each year on Hyperloop. The total cost of Hyperloop in this     analysis is under $6 billion USD. Amortizing this capital cost over 20 years and     adding daily operational costs gives a total of about $20 USD (in current year     dollars) plus operating costs per one-way ticket on the passenger Hyperloop.    For aerodynamic efficiency, the velocity of a capsule in the Hyperloop is     - typically: 300 mph (480 kph) where local geography necessitates a tube bend radii       < 1.0 mile (1.6 km)    - 760 mph (1,220 kph) where local geography allows a tube bend > 3.0    miles (4.8 km) or where local geography permits a straight tube.

Best comment on reddit so far "this is a pipe dream"

* I don't think the Hyperloop is viable and I hope they kill the $100B High Speed Rail (HSR) project before it ruins the SF Peninsula and budgets across the state.

* Setting aside the $100B HSR cost (yes, I know current estimates are $70B but it was sold at $10B and will easily exceed $100B if/when completed) the operating costs will have to be subsidized for every minute of its existence just like every other govt boondoggle. This is a white elephant and, in case you weren't paying attention, California and most cites are or soon will be bankrupt. We can't afford this, cut our losses now.

* If I was made Bay Area/CA public transportation csar (with suitable budget and dictatorial powers) my first step would be to extend BART through San Jose so it actually loops the bay and (finally) complete BART. (I am old enough to recall that that was the original design)

* I do think a high speed rail connection SF/LA is economically viable but would need to do research and crunch numbers while finishing BART. I would move the SJC airport south (with a BART extension) to Morgan Hill/South San Jose and build the connection from there to LA.

* From SJ to LA I would confiscate I5, leave two lanes for truckers and local traffic but build a high speed (300MPH) car/ferry train system so you could be blasted to LA in a little over an hour and have your car there when you arrive. Home by dinner.

* I would build a nuclear plant somewhere halfway between LA and SF on I5 so my trains would not have to use diesel fuel (too smoggy) or solar (too expensive).

Nothing here is any less fanciful than Musk's musings and far, far more practical.

None of this is to say that Hyperloop is a bad idea. The idea sounds very interesting and I'd rather spend sixty billion building a Hyperloop --even if it fails-- than the ridiculous California high speed rail project.

Cost is probably off by an order of magnitude, if not more. Why? Unions and other groups. Building anything in this country costs massively more (and takes significantly longer) than one could imagine because of our unions are not business symbiotic. The goal of union leadership is to extract as much as they can out of the businesses they infect, even if this means their demise.

A lot of the unions that would be part of such a project have some of the laziest and most problematic people working for them. If you come from the Silicon Valley tech world my words make no sense to you. In fact, you might think I am nuts. All I have to say is: Do a good size trade show exhibit at a few of the unionized convention centers in the US and then see what you think about US unions. Then repeat that experience at various locations in Europe and Japan and see the difference. I have done just that. US labor unions are destroying our country from the inside out.

How many significant new civil engineering projects in the US can you name over the last, say, fifty years. Right.

Hyperloop cost would be way more than this paper seems to predict.

The political factor is grossly underestimated. Our reality is that we live at a time of political deadlock. Nobody can or wants to make a decision and the decisions we do make tend to be suboptimal, sometimes grotesquely so: example, California high speed rail.

Finally, it addresses the wrong market. I am not sure why people insist on applying trains to transporting people in the US. Sorry to resort to reality folks: If you build it they will NOT come. We do not have that culture and you will not inspire it simply by building trains. You'd have to forcefully push people in that direction through legislation that would make it too expensive to not use rail. In other words you'd have to declare war against other methods of transportation through punitive actions.

The right place for high speed rail in the US is cargo, not passenger rail. If we could evolve our cargo rail systems to move at 300 km/hr rather than 50 the consequences would provide economic benefits and development beyond a century.

The final point is related to politics. We have a decision making system that allows anyone to vote. And, while this is commendable, it does create horrible problems. Imagine allowing a random group of, say, ten people deciding whether or not your child should have surgery. I'd be surprised if anyone thought this to be a good idea. No, most people would rather have a group of experts in the field, more than likely MD's in this case, vote for such a decision. The ridiculous California high speed rail project is a result of hordes of low-information, mathematically challenged, technologically ignorant and financially ignorant voters being led by the nose by unions, media and political forces.

How do you move forward when people like that can vote on these issues and their vote has equal value to that of an expert in the relevant fields: a PhD in Physics, an engineer, a financial expert, etc.

Regrettably this is not a technological problem. It is far more complex than that.

Note that the UK's new high speed rail (HS2) is budgeted at 33bn ($51bn) and likely to exceed that[0]. Being mostly straight, and across land already approved for rail use, it seems like an ideal candidate for a hyperloop alternative.

At 120 miles long[1] compared to the SF<->LA ~350 miles, a UK hyperloop would be even cheaper, especially since the major cost is the tube itself. A back of the envelope calculation[2] gives a cost of about 1.9bn ($2.9bn) which is suspiciously, almost absurdly, cheap.

If anyone can find any flaws in this argument (specifically related to e.g. UK-specific issues/laws that I may be unaware of) I'd be very interested to hear them!

I'm impressed, but I'm afraid Hyperloop's operation is modeled after airplanes, while the actual use of the system would be closer to a city bus.

>All capsules would have direct radio contact with station operators in case of emergencies, allowing passengers to report any incident, to request help andto receive assistance. In addition, all capsules would be fitted with first aid equipment

>Typical times between an emergency and access to a physician should be shorter than if an incident happened during airplane takeoff. In the case of the airplane, the route would need to be adjusted, other planes rerouted, runways cleared, airplane landed, taxi to a gate, and doors opened. An emergency in a Hyperloop capsule simply requires the system to complete the planned journey and meet emergency personnel at the destination.

What happens if a brawl erupts inside a capsule? What happens if a suicide bomber boards the Hyperloop?

Sorry, but I do not believe this will be cheaper than conventional rail. This is essentially a vacuum tunnel. Ok it is not a perfect vacuum but it is still supposed to keep 1/1000th of the earth's pressure.* Keeping such a vacuum over several hundred miles of metal tubing would be very very expensive.

This may work but it will be several times more expensive than the HSR system.

From my skimming of the PDF, it sounds like a pneumatic tube transportation system with a compressor fan on the front of the vehicle that moves high-pressure air from the front to the back maintaining a low-pressure state around the vehicle. Kind of like an Earth-bound Alcubierre drive.

I'm really curious about turns and switches. The latter more about loading and unloading. If you have a platform to carry 300 people / hr to or from the other city how do you load them and keep them organized.

The failure scenarios are interesting too. Lets say a tube breaks, if the linear motors are spaced out, how do they brake? Turn off the air lift? Does that then destroy the tube they are in? What is the emergency exit like?

Wow. I was expecting it to be something like the UW Ram Accelerator (RAMAC), but he put a fan in front. I was thinking it would have natural gas/detonation for propulsion, using the ram jet principle, and continuous acceleration, but I guess that rapidly gets you to totally absurd speeds (10km/sec+) and wouldn't really be viable, plus humans aren't so into 10G+ acceleration even when mounted laterally.

I would totally ride this. I hope there's a way for California to build it, and more importantly, I hope we can fix our government somehow to allow projects like this to actually happen in multiple fields.

So, a sealed tube from A to Z, passing B through Y. No benefit to B through Y at all. So why do B through Y allow the tube to pass through?

When railways happened, B through Y believed they would see economic benefit, and often did. They got a station. Not so here, correct?

There for, wouldn't this need a government to force it through? How would that happen in the USA?

To me this is where the idea runs in to the buffers, as it were.

A wonderful proposal and inspiring: I think the air bearing, partially evacuated tube and axial flow compressor powered by onboard battery are an innovative combination worth exploring, and I am sure with the correct leadership and political will could produce a really useful enhancement of transport infrastruture. However on reading many of the comments bemoaning current state of construction in the US, as well as unions and vested interests; had to provide this quote of Machiavelli's:It ought to be remembered that there is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things. Because the innovator has for enemies all those who have done well under the old conditions, and lukewarm defenders in those who may do well under the new. This coolness arises partly from fear of the opponents, who have the laws on their side, and partly from the incredulity of men, who do not readily believe in new things until they have had a long experience of them.

Seems like this would be particularly vulnerable to terrorist attacks. There is a huge surface area that needs to be protected (tubes/pylons). If there are pods leaving every thirty seconds and traveling at supersonic speeds then taking out one pylon could kill several hundred people and leave the entire train inoperable. In a future where this design was used extensively to connect cities on the coasts it would quickly become a critical piece of transportation infrastructure. Attacking several arcs of the city graph simultaneously would be utterly debilitating. Especially if the system's relative efficiency leads to the displacement of other forms of transportation.

If he's going to block the light to farms he'll have to pay them for the lost crops, and then he might as well just buy the land.

I like the idea of transporting cars with passengers or just cars/SUVs. That would be ideal. Travel from point a to point b like a ferry. Or extension of our current super highway network. Use your personal transport machine after arrival. In most of the USA when traveling outside the dense urban areas driving a automobile is the preferred form of transportation. It would make the world a smaller place much like how cars and paved roads did 100 years ago. If we could hyper transport our vehicles at large chunks of distances say 300+ mile integers. I could only imagine this future.

Freight shipping would greatly benefit. Build a freight tube only across the US mainland. Amazon Prime? Same day delivery.

Aside from the whole "will they actually build it" debate, I'm worried that if they do, the capsule ceiling won't be high enough for someone fairly tall (let's say 6'5'' or taller) to sit in comfortably. I'd assume the height of the capsule will have some effect on the drag involved, as well as the necessary size of the tube, so it makes sense to make it as short as possible.

Musk himself stands just below 6', so he may not naturally think of us taller folk. I'd hate to have to slouch for the trip, even if it is only projected to be 35 minutes.

edit: dear tall people who have ridden in one of Tesla's cars: how's the headroom in a Model S?

I have three things to say about this:

1. Many people are horrified by the thought of not being a simple worker bee. They say they want change, but they don't. They want the security of someone else taking care of them. The reason wealth exists is because there are people that cannot live this way, and thus, make their own way. You cannot fault hard working business owners because their employees put themselves in a place to require said employment in order to sustain a life they consider normal.

2. There will always be wealth. If the US gave up capitalism in favor of socialism, the money would be placed in the hands of the whole, and in this case, the government. At that point, the government has the money and the power. We're screwed.

3. Life is suffering. There is no perfection on this realm. Solve this problem and another will follow. This is a symptom of life in samsara. Bukowski recognized this, which is why he talked of a simple life without possessions. If you truly want to break free of 'the man,' you'll have to life a life defined by something other than money, objects, and achievements. For most of us, this is nearly impossible. Middle ground is an illusion.

Some people balk at the idea of "wage slavery," primarily because they think it is so different from the traditional slavery that it should not be called that.

But the question is, if you are doing something and the alternative is starvation and death, are you really a free human being? If you think about it for a while, the answer becomes clear: you are not free. Sure, you have the freedom to switch from one slave-owner to another, but at no point in the process do you have real freedom.

When I was 50 I had published a universe of designs. But all I have done before the the age of 70 is not worth bothering with. At 75 I'll have learned something of the pattern of nature, of animals, of plants, of trees, birds, fish and insects. When I am 80 you will see real progress. At 90 I shall have cut my way deeply into the mystery of life itself. At 100, I shall be a marvelous artist. At 110, everything I create; a dot, a line, will jump to life as never before.

I do love my job, though there is so much more I want to do with my life - so much more I could do that (as far as I can tell) would really help humanity. Unfortunately I'm locked into working because of student loans and overall cost of living. I try to do work in my free time but sadly 3 hours a night does not build a company with enough revenue to grant me freedom.

By the time I've earned enough from my job to afford not having a job I worry I'll have moved on to a different life stage where kids will take up my evenings.

I know I'm not the only talented, driven 20-something in this situation and with student loans recently so high, it is a pity to think that overall out generation will have fewer who are able to make their ideas real because of it. Thanks to YC for offsetting that effect and helping us believe we can "get free".

I've been at my current full-time job a bit over a year. The previous six years were a mix of freelance, contract, and startup work -- sometimes full-time, sometimes way-more-than-full-time, and sometimes not at all... but usually part-time.

There are some things I like about the current job, and if I stick around at least another six months, I'll likely play a key role in overhauling the front end of a major automaker's website using state-of-the art. Not a bad feather to stick in a cap.

On the other hand, the chances that I'll do anything else in the meanwhile seem pretty slim. I notice in the last year alone, my energy for original/personal projects is diminished, I feel less creative/thoughtful in general -- and arguably even less interesting than during the aforementioned freelance period. I do feel, as Bukowski put it, somewhat emptied out by my work.

It's possible what I really need is a different full-time gig, since I have been in some full-time situations that felt energizing. But I'm starting to be convinced that when I'm hiring myself out part-time, I stay more personally grounded and sharper as far as my general skills and strength in the field goes.

Unfortunately, steady skilled part-time employment seems to be considerably more difficult to find than full-time.

(4) i am very fortunate to be in this position, and i really don't want to waste it.

so i've been giving this topic some serious thought. to work or not to work? that is the question.

I don't happen to believe the wage system is slavery (I do happen to believe we have a modern slavery system, but that's another story)

"They never pay the slaves enough so they can get free, just enough so they can stay alive and come back to work." But then why don't the slaves leave? Unlike in the past, nobody is holding a gun to their head. One possibility, probably popular among entrepreneurial types, is the slaves don't leave, because they don't think they can leave. It's a problem that is easily solved! All the boring types need is a little bit of education, for them to learn that leaving is possibility.

But maybe, what scares us a little bit, is that maybe the slaves don't want to leave. They value that security that the boring life brings them (that is why they complain "it ain't right" - because they have lost something they really valued). This is the really scary thing, because we don't want to be boring but we could see ourselves making the same choice. At the same time we don't understand the choice of the slaves to not leave, we identify with it at a level that we maybe can't explain. But is it a wrong choice? Who are we to judge others for choosing security over wealth or self-exploration? Maybe we are at a knife edge- a little bit less motivation here, a marginal preference there, a taste of failure here, and we, too, would pick security over wealth (of money, of intellect, of experience). I think that the strange paternalistic attitude of the passage is a result of the fear - the fear of that condition.

"They never pay the slaves enough so they can get free, just enough so they can stay alive and come back to work."

I suspect the author is being intentionally misleading regarding the costs of staying alive. It doesn't take $20,000/year. More like $5,000, and even that is being generous.

Early Retirement Extreme and other books cover this in more detail, of course.

I do agree with the overall sentiment of his article, but the concept that the current state of affairs is some kind of intentional conspiracy is incorrect. People like the security of being indebted and forced to work, it seems. They are not forced into such a life.

I support and understand what he's saying, but I think too many times we set up this false choice between "pursuing our dreams" and "working for the man"

There's honor -- and authenticity -- in making choices for your life that involve working in the system.

I used to look down on those who worked jobs they hated and would say things like "That's just not for me. I don't know how you can do it." until one day somebody took me aside and pointed out what an insulting and condescending attitude I had. I was being a jerk, a well-paid, able-to-pick-what-I-want-to-do jerk. Other people did not have the same lives or face the same choices as I did. I should respect their uniqueness and decisions -- even if they loudly and publicly complained about them.

I have learned that for myself it is too easy to go off on a wild tangent about how one lifestyle is so much better than another, talking about slavery and such, just like in this letter. Basically I was being a judgmental prick, substituting my values for other people's and then declaring that my choices and values were best for everybody.

I finally realized that the quality of life is something each of us owns through our own personal choices.

So I don't do that anymore.

The early part of my career was spent chasing everything, and ironically, it was when I had the least amount of money. In 1998 I got my first job and immediately got a nice apartment in which to live and a decent car to get around. Even with these somewhat reasonable purchases I was already butting up against what I could afford. And by afford, I mean how much money I had. Soon enough the credit card debt slipped in and I was trapped. Trapped by my debt and all of the obligations that went with it.

This cycle did not stop until I was making a bit more money and finally got serious about saving and investing. When this happened my other priorities shifted dramatically. I was no longer obsessed about getting the newest / best thing or what have you. I paid off my debts and vowed to from then on always live well beneath my means, which I have.

Since that time Ive never felt trapped. Im disciplined about long term saving and having at least six months of normal living expenses in the bank. Ive quit jobs that I simply did not like and later found other jobs that I did. I only regret that I did not do this sooner.

Few questions. Is Grasshopper intended to be a vehicle that ships a payload into a low earth orbit and return itself back to the launch pad?

With that, a question of descent, once it's reached orbit and released its payload, would it re-enter with a short burn towards its earthly destination, decelerate with, say, parachutes, and then do its final descent onto the pad with the rocket? I can't see it doing its entire descent with a rocket, that would use so much fuel, and require so much extra weight.

"Await" is fantastic, and having using it for JavaScript (via TameJS and then IcedCoffeeScript), it makes things a lot easier and clearer.

That being said, I don't think the comparison between callbacks and goto is valid.

"Goto" allows you to create horrible spaghetti-code programs, and getting rid of it forces you to structure your programs better.

"Await", fundamentally, isn't really anything more than syntactic sugar (except for exception handling, which is a good thing). "Await" doesn't change how your program is structured at all, it just changes the visual representation of your code -- from indentations in a non-linear order, to vertical and linear order. It's definitely a nice improvement, and makes code easier to understand (and allows for better exception handling), but it's not actually changing the way your program is fundamentally structured.

And finally, "await" is only applicable when a single callback gets called once at the end. If you're passing a callback that gets used repeatedly (a sorting function, for example), then normal-style callbacks are still necessary, and not harmful at all. Sometimes they can be short lambdas, sometimes they're necessarily much larger.

In sum: "await" is great, but there's nothing inherently harmful about callbacks, the way "goto" is. To the contrary -- callbacks are amazingly useful, and amazingly powerful in languages like JavaScript. "Await" just makes them nicer.

You get a similar interface in Python's Twisted using the @inlineCallbacks decorator:

    @inlineCallbacks    def example():        try:            obtain_some_lock()            ui_status("Fetching file...")            result = yield fetch_file_from_server(args)            ui_status("Uploading file...")            yield post_file_to_other_server(result)            ui_status("Done.")        except SomeError as e:            ui_status("Error: %s" % e.msg)        finally:            release_some_lock()
I must say that this style of writing async code is much friendlier than descending into callback hell.

There is work to make a similar async interface native in Python 3, in PEP 3156 http://www.python.org/dev/peps/pep-3156/, so this should become more widely available even to those who don't use Twisted.

I'm not buying the c# async/await kool-aid.

Async, sure, I'm down with that, but I've used the c# async stuff now, and while it makes it the app somewhat faster, it has three major downsides (that I encountered):

- Infects everything; suddenly your whole application has to be async.

- Debugging becomes a massive headache, because you end up in weird situations where the request has completed before some async operation completes, the debugger gets scared and stops working.

- It's really hard to test properly.

The only good reason for using it is that because of the infection-property back fitting async to your application is a major headache; if you might use it, you have to use it from the beginning or you get a huge backlog of refactoring and test fixes to do.

-___- 'I might use this for some performance bottleneck I don't yet know about, so better start using it now...' yeah, that's a thing: premature optimization.

As someone who only recently switched to Node.js from PHP I personally haven't had any difficulty switching over to the callback frame of mind, and I haven't experienced the "callback hell" so many people complain about. At first I was hesitant to start with Node because I saw blog posts by people bemoaning the spaghetti callback code that they ended up with. But I haven't experienced any of that, although I am a relatively newbie Node programmer with only a few months of experience so far. My current project is quite non trivial as well, running into the tens of thousands of lines so far.

The key I've discovered to nicely organizing callbacks is to avoid anonymous callback functions unless absolutely necessary for a particular scope, or unless the function is going to be so trivial and short that it can be read in a single glance. By passing all longer, non trivial callback functions in by name you can break a task up into clear functional components, and then have all the asynchronous flow magic happen in one concise place where it is easy to determine the flow by looking at the async structure and the function names for each callback function.

Another major advantage to a code organization like this is that once you have your code such that each step has it's own discrete function instead of being some inception style anonymous function tucked away inside another function inside another callback it allows you to properly unit test individual functional steps to ensure that not only is your code working and bug free at the top level functions, but also that each of the individual asynchronous steps that may make up some of your more complicated logic are working properly.

Most of the bad examples of callback hell that I see have anonymous callback functions inside anonymous callback functions, often many levels deep. Of course that is going to be a nightmare to maintain and debug. Callbacks are not the problem though. Badly organized and written code is the problem. Callbacks allow you to write nightmarish code, but they also allow you to write some really beautiful and maintainable code if you use them properly.

danenania 2 days ago 0 replies      
I generally agree that there are better ways to handle asynchronous control flow than callbacks, but I think this is exaggerated. As in most posts like this, the callback soup examples are difficult to follow primarily because they are horribly written, not because of callbacks.

As long as you write decent code, the main impediment to asynchronous programming is reasoning asynchronously, not syntax. If you require complex asynchronous logic and don't use an appropriate algorithm, you'll end up in the muck whether you use callbacks or await.

Taking go as an example: while I agree that the go statement is more elegant than a callback approach, I see it as quite a minor win compared to channels. The go statement is convenient syntax, but channels are what make concurrency in go feel so robust, and it's a pattern than can be applied just as well in a language that uses callbacks.

Anonymous Callbacks != Callbacks

Callbacks have been around forever in C using named functions, and are not specific to either the current generation of programming languages or programmers. One can still use a named function instead of a locally constructed lambda to represent a callback in a high level languages.

The primary difference is that when declaring named functions non-locally, one must explicitly share state through the parameter rather than implicitly sharing state through lexical scoping. It seems more accurate to label the problem of nesting lambdas to the point of ambiguity as "Lambda Abuse" or "Lexical Scoping Abuse" rather than "Callback Hell".

I agree, although I think callbacks are more like COME FROM than goto. You see a function being passed somewhere as a callback, and you know the block is going to execute at some point, but most of the time you have no idea what the codepath that calls you back looks like.

There's nothing more frustrating than trying to debug why a callback isn't being called. Who calls it? How do I set a breakpoint somewhere to see why it isn't being called? etc.

The one thing that is still missing from await and other green thread approaches is cheap global contexts. Isolating every different green thread so they can't implicitly share state is the obvious next step.

The problem is simply that those languages are not Lisp.

Once good patterns of use of GOTO were found, it was natural to critisize random uses, and to wrap good uses in a lisp macro. Or in a new while or for "instruction".

But then the next construct is discovered, and its bad uses considered harmful, and its good uses need to be wrapped. In lisp, mere programmers will just write the next macro to abstract away this new construct. Other programming languages need to evolve or have new language invented with new "instructions".

So now it's the callbacks. Yes, in lisp we'd just use closures, but this is only a building block for higher level constructs. If those "callbacks" are needed to represent futures, then we'd implement those futures, as a mere lisp macro.

Yes, in the other languages you're still powerless, and need to wait for the language designers to feel the pressure and implement a new "future" instruction or whatever.

Any language construct can be considered harmful eventually. Concretely, a repeative use is a hint of that: the construct becomes meaningless because it's used all the time, or apparently randomly (just like those GOTOs). But it's not that the construct is bad, it's that its usage is not abstracted away in higher level constructs. And the only way to do that is lisp macros.

So unless you're programming in lisp (a homoiconic programming language that let you write easily macros in the language itself), you will always reach a point where some construct will be able to be considered harmful for lack of a way to abstract its uses away.

I don't understand what the big deal is. Callbacks are OK. They're less cumbersome if the language you're using has smaller function definitions.

Callbacks 'get crazy' when you've got more than one I think, and thankfully someone smart has made a library you can use to manage them!

https://github.com/caolan/async

Saying that, I don't mind the way things look with the whole await/async stuff in C# and etc. However I don't think we should be waving our arms around saying callbacks are like goto, they so completely are not! I have written heaps of stuff with callbacks and it's _not that confusing or unmaintainable_. It's just different.

Anonymous callbacks are very powerful and very important. They will make you feel bad for unnecessary nesting. They will force you to learn how to abstract better, especially state changes. They will show you how nice and reliable code can be if it doesn't have shared states across multiple functions and how easy it is to understand consistent code with explicit continuations and how to write one yourself. They will make you a better programmer.

And "await" can only make it harder to visually distinguish which piece of code is executed in parallel and which is executed sequentially. Nesting makes it explicit.

(C/OS developer spiel)

I'm sick of these app developers assuming that using "goto" is bad practice. The fact is that "goto" is used plenty in great production code you're probably running right now.[1] I'd like to know a cleaner way to abort a function into its cleanup phase when a function call returns an error. And "goto" statements are extremely simple to handle for even the most naive of compilers.

This is all simply sugar to hide behind-the-scenes threading behind very narrow interfaces. Which isn't necessarily bad, but it's fun to see it suddenly in favour again and presented as something new.

E.g. Simula67 had Call and Detach for the basic case, and Activate(object representing async behaviour) and Wait(queue) that would both depending on need often be used for the same purpose (as well as a number of other operations). We had to write code using those methods in Simula67 in my introduction to programming class first semester at university...

Why do people insist on analysing things using analogies? Analogies are useful for explaining a concept that might not be obvious. Saying callbacks are like gotos, gotos are bad, therefore callbacks are bad is ridiculous.

And he gives some sample code where the 'problem' is nothing to do with callbacks, its just nested lambdas. In fact I find that code quite easy to read, and would be very interested in seeing the same functionality implemented some other way, bearing in mind it is quite a difficult problem to synchronize multiple async operations and usually requires horrible code using multiple mutex.

You can write any article like this about anything, here is the formula:

- pick a language feature

- write an article with the title "<language feature> as our Generation's Goto Statement"

- write an example where you misuse <language feature> and over generalize it

- show a workaround that doesn't really save the trouble of actually thinking before typing

The hard thing about callbacks is that you need to think about asynchronous processes which can be hard, the callbacks are not the problem so replacing them with something else won't help you too much.

Meh.

Callbacks are a very limited way to do asynchronous programming. However they are a good way to create interfaces that let you call methods and insert your own functionality in the middle.

So yes. Better async is good. But don't take away callbacks. They have their uses.

Completely OT, but when Dijkstra says:

>My second remark is that our intellectual powers are rather geared to master static relations and that our powers to visualize processes evolving in time are relatively poorly developed. For that reason we should do (as wise programmers aware of our limitations) our utmost to shorten the conceptual gap between the static program and the dynamic process, to make the correspondence between the program (spread out in text space) and the process (spread out in time) as trivial as possible.

He's touching on a crucial point in Immanuel Kant's philosophy. Kant theorized that though humans received their sensations as a constant stream of input in time (which is an internal condition of human beings, not a feature of bare reality), we can't actually do anything with that stream without applying concepts so as to form concrete (or abstract) objects, i.e. chairs, black holes, mothers, etc. But how would our minds know when to apply this concept or the other? Kant's reply was that our minds look for little clues called 'schematisms' which tell us what the most appropriate fundamental concept to apply to a part of the stream is, upon which others could be combined to produce objective representations we can think and act upon.

Almost a hundred years later, Nietzsche will claim (paraphrasing) that a measure of strength in a human being is the extent to which to which they can 'consume' phenomena in time, weakness being how direly one needs to apply a static idea to phenomena (like morals, stereotypes, prejudices, cause and effect, etc).

I'm just noting an interesting entry point into an old philosophical conversation. If it's understandable then I hope someone finds it interesting.

background orderStatus = orderPizza();

turnOnXbox();

while(orderStatus == 'not ready') {

eat();

"I have just delegated the bookkeeping to the compiler."

That's not obviously a good thing. Debugging the compiler (or just figuring out why it did something, even if correct) is far more difficult than debugging application code. Given the choice between implementing behavior with application code (or a library function) or adding semantics to the language, I prefer the former because it's much easier to reason about code written in a simple language than to memorize the semantics of a complex language.

The ease with which callbacks can be created leads people to create them carelessly and excessively. While I like what the article has to say, there are ways to write callback heavy code that do not get ugly so fast. Looking at the iOS nested block example from Marco Arment -- the first step is to not do everything inline. Then the code suddenly becomes clear and the argument becomes one of syntax sugar.

Comparing callbacks to goto is a tad unfair. They don't merely solve async issues, but also event handling and dynamic systems to name two common uses. I don't see a better solution on the table. Using callbacks to write deeply async code is the real problem. And while async/await may help with this problem, it still won't tell you why step 3 never finishes, because it's still waiting for a come from.

I found that sometimes it helps to build a state machine to effectively run the show and try to limit callbacks to setting flags and/or navigating the state tree. State machines make following code functionality a breeze, even when dealing with really complex logic.

How is "await" any different from a regular blocking system call? A regular system call does exactly what is being described: The system call happens, and then when it is finished, execution resumes where it left off.

(Yes, this makes the thread block... which is why you have multiple threads. I think the answer will have something to do with this, though...)

shenanigans. Pyramids (at least in js) can be easily avoided by simply naming your functions. Treating them like the first class objects they are. Naming the function means you are no longer going to an arbitrary code block, but instead going to a concept whose name, doc string, and (through hoisting) position on the page illuminate its purpose.

Callbacks aren't bad. Pyramids are bad. Stop writing pyramids.

Nodejs also establishes a nice api for callback functions-- in particular, callbacks are defined with an `error` and a `data` argument. You handle the error if it is non-null, otherwise execute `data`.

If you want to avoid callbacks, Node also provides event emitters, and streams. Streams in particular provide a nice api for dealing with event based programming.

I think this article misses a main point and that's the fact that all await does it take a function that used to be asynchronous and makes it synchronous. While yes, there are definitely use cases where that is nice, in general I think that if you want to use an await command, why are you making a call that was meant to be async? You are defeating the whole point of async calls.

Yes I know a lot of standard libraries have calls that are async and you may not really need for them to be async but I don't think that this is the case often enough that we should abandon callbacks and the like and go back to an age where all code must be synchronous. I know the author isn't saying it to that extreme necessarily, but his comparing callbacks to gotos is extreme as well.

Few people remember it, but the same thing happened at HP. It used to be that HP engineers were expressly given Friday afternoons and full access to company resources to just play with new ideas. Among other things, this led to HP owning the printer market.

Then "professional" management came in and killed the proverbial goose. They had to focus more on the "bottom line". To do what was easy to measure and track, rather than what was necessary for the next step of the company, and now HP is a mere shadow of its former glory -- directionless and bleeding.

3M and Corning have largely avoided this fate, but it seems that Google won't. This should make a lot of entrepreneurs happy, as there will continue to be a lot of top-down management-driven products that, if history shows, will continue to be market failures.

I am a Googler. I will only speak to my personal experience, and the experience of people around me: 20% time still exists, and is encouraged as a mechanism to explore exciting new ideas without the complexity and cost of a real product.

My last three years were spent turning my 20% project into a product, and my job now is spent turning another 20% project into a product. There was never any management pressure from any of my managers to not work on 20% projects; my performance reviews were consistent with a productive Googler.

Calling 20% time 120% time is fair. Realistically it's hard to do your day job productively and also build a new project from scratch. You have to be willing to put in hours outside of your normal job to be successful.

What 20% time really means is that you- as a Google eng- have access to, and can use, Google's compute infrastructure to experiment and build new systems. The infrastructure, and the associated software tools, can be leveraged in 20% time to make an eng far more productive than they normally would be. Certainly I, and many other Googlers, are simply super-motivated and willing to use our free time to work on projects that use our infrstructure because we're intrinsically interested in using these things to make new products.

I'd point out that Page and Brin predicted the course of their own search engine, and perhaps their own company, in 1998:

The goals of the advertising business model do not always correspond to providing quality search to users.

We expect that advertising funded search engines will be inherently biased towards the advertisers and away from the needs of the consumers.

Advertising income often provides an incentive to provide poor quality search results.

"Since it is very difficult even for experts to evaluate search engines, search engine bias is particularly insidious. A good example was OpenText, which was reported to be selling companies the right to be listed at the top of the search results for particular queries. This type of bias is much more insidious than advertising, because it is not clear who deserves to be there, and who is willing to pay money to be listed.

We believe the issue of advertising causes enough mixed incentives that it is crucial to have a competitive search engine that is transparent and in the academic realm.

Search engines have migrated from the academic domain to the commercial. Up until now most search engine development has gone on at companies with little publication of technical details. This causes search engine technology to remain largely a black art and to be advertising oriented. With Google, we have a strong goal to push more development and understanding into the academic realm.

20% time isn't dead -- I have been using it at Google consistently for over 7 years, and it has immensely benefited me. You don't need any permission, at least in engineering.

However, I would agree that it is "as good as dead". What killed 20% time? Stack ranking.

Google's perf management is basically an elaborate game where using 20% time is a losing move. In my time there, this has become markedly more the case. I have done many engineering/coding 20% projects and other non-engineering projects, with probably 20-40% producing "real" results (which over 7 years I think has been more than worth it for the company). But these projects are generally not rewarded. Part of the problem is that you actually need 40% time now at Google -- 20% to do stuff, then 20% to tell everyone what you did (sell it).

I am a bit disappointed that relatively few of my peers will consciously make the tradeoff of accepting a slower promotion rate in return for learning new things. Promotion optimizes for depth and not breadth. Breadth -- connecting disparate ideas -- is almost invariably what's needed for groundbreaking innovation.

Talking to a friend at 3M (who has been there 20+ years, an engineer with dozens of patents) I am told that while 15% officially still exists, for a long time it's effectively meant working 115% of hours.

Nonetheless the tradition allowing self-directed research continues at 3M - and this might mean using lab resources, or creating prototypes without getting approval.

There are a lot of good remarks in this thread.

I will try to add a point I haven't seen here yet:

Once I was in a big company with a big, famousresearch lab.

The group I was in, just three of us, was led by aguy who had taken some technical work and publishedsome papers. The journals were peer-reviewed butsemi-popular so reached some ordinary businesscustomers. The papers fit in with a lot of hype atthe time.

So, some of the customers picked up a phone andcalled our group for more information. So, presto,we got contact with real customers otherwiseessentially forbidden in research.

Why forbidden? Because the sales/marketing guyswanted to be the guys who had total control over allcontact with customers.

Eventually our little group broke up, and I wantedto do some research that would lead to products tobe sold to customers. I started to discover that noone in the company wanted that. The big guys inresearch wanted to throttle all contacts outsideresearch and mostly didn't want any. The people insales, marketing, product development, and productproduction didn't want to deal with anything newfrom research. No one wanted a research worker beetalking to real customers.

Next, when research did come up with something thatmight be of interest to real customers, no onewanted to pursue that opportunity. Again, themarketing people wanted to be the source of all newproduct/service initiatives. No one in researchwanted a research worker bee to get credit/blamehaving a product go from research to success/failurein the market.

In the end, research was forced to be essentiallyirrelevant to the business. Finally research wasturned into a patent shop so that lawyers could takethe big patent portfolio, go to companies, claimpatent infringement, and 'license' the patentportfolio.

Point: Generally, a business organization, given anice new product/service to offer their customers,has multiple layers of organizations and people,processes, reasons, etc. why they just do not, notwant to come out with anything new. Period.

Curiously, yes, some of the people at some of thecustomer organizations were eager to work with ourgroup in research as a way to look more innovativewithin their own organizations. Here, of course,they didn't have to work through layers ofmanagers but only had to exercise their ownfreedom to handle their own responsibilities.

So, lesson: Commonly individuals are ready to doand offer new things to others or try new thingsfrom others, but it's the layers of managers whoblock such things.

So, the blockage of these layers of managers is oneof the main reasons and opportunities forentrepreneurship.

Yes, it's dumber than paint, but it's usually theway of the world.

This is a strategic shift for Google that has implications for how the company stays competitive, yet there has never been an official acknowledgement by Google management that the policy is moribund. Google didnt respond to a request for comment from Quartz."

What I've heard is more nuanced: the policy is not dead, but it's very hard to both satisfy the core demands of your job and maintain 20% time. So it's not dead, but possibly not an actual priority in the culture the way it used to be..?

I explicitly asked to use 20%-time to work on a side project (i.e., literally take 1 day a week to work on it) and was refused.

20% time has always been a great marketing gimmick for Google. I remember interviewing candidates and mentioning it as a bonus to prospective candidates - most employees mentioned it as a bonus because we were inculcated into believing it was actually a bonus. It's much easier to see that it was never a real perk once you're outside the bubble.

It probably made more sense to have 20% time when Google didn't have tens of thousands of engineers. When you have a few hundred really smart people all working in the same building back in the early 2000's in Mountain View, it was I imagine a different thing than it would be now.

This means that a lowly engineer with a great idea will leave Google to develop it instead of developing it at Google. Perhaps, this is a good outcome given the way Google keeps killing web services that people find useful but aren't profitable for Google.

A Google recruiter, while doing his spiel, told me in a light-hearted, offhand manner that some engineers call it "120% time". Having lurked here long enough and read similar sentiments from ex- and current google employees, it wasn't really news to me, but I was pleasantly surprised at his candor.

But do any of the other companies listed do 20% time? AFAIK, they only have infrequent "hack days".

Guess who advised Larry Page to focus on a small number of projects? Steve Jobs.[1] It seems like Larry's acceptance of Jobs' advice has sabotaged Google. I'm no conspiracy theorist, but one does wonder if this was Jobs' secret intention.

Businesses don't live and grow forever. They have a lifecycle, and when they get big enough and their business model becomes mature enough, they divert resources away from risky innovation and toward defending the fortune they've amassed, defending their primary cash cow products against competition through anticompetitive practices like patent litigation, and promising steady returns to shareholders. The problem is, this swing toward conservatism tends to fossilize both the product and the organization.

If you fully de-risk your company, it will stagnate. No risk, no reward either. And in Google's quest to kill Microsoft, they are becoming Microsoft.

This is the opposite of Black Swan farming.

With any project like 20% time, you should expect that almost everything produced will be worthless. So what? All you need are 1-2 big hits to justify the entire program.

Letting employees work on what they think will be valuable is a bottom up approach that can reveal knowledge that's inaccessible to managers.

Some comments on here say that the program 'only' created Gmail. That's been a massive success for Google. That + the smaller successes it has led to likely justify all the projects that didn't pan out.

It's human nature to stop "screwing around" in order to get "real" work done and make your boss happy. The only way to keep 20% time is to force everyone to take it. If others on your team stop doing it, then the competitive balance isn't fair anymore. If your boss can get away with unofficially taking it from you, then she will. Something like 20% time must be in the company policies with punishment for those that discourage it.

This doesn't seem all that surprising. You get what you measure. If Google has been placing a greater weight on direct short-term contributions than on blue-sky projects, and then putting employees in competition with one another, then of course employees are going to feel under pressure to reallocate that 20% of the time toward the stuff that makes them money. Some persist anyway, because of personal satisfaction or (much less often) sincere belief that what they're working on in their 20% time will eventually win big for both themselves and Google, but employees take those risks and make those deals at every company. The middle managers have no reason to support it as the general case, and most employees don't have the backbone to force the issue. Ultimately it's a bit like working from home. Some do it even at companies that don't have a policy for it, and some companies that do have such a policy don't really make it possible.

Seems odd that nobody is mentioning Google's in-house makerspace, hackathons, and 20% weeks (where engineers without 20% projects, or who prefer time-boxed commitments, take a week once a quarter to work on stuff). I ran a 20% week project last year - or maybe the year before? - and there are several really fantastic people working tirelessly on the Garage and other makerspace stuff to ensure that the 20% mindset is alive and kicking.

I totally understand the "management killing freedom of experimentation" comments, but they are only one side of the story, and a side explicitly pulled from disgruntled Xooglers at that.

The Garage is one of the things I miss most about Google - both the makerspace itself, and what it represents. We hosted several internal hackathons there, both within and outside the intern season and had great success.

Bullshit. I'm a Googler, and I'm 20%ing today (as soon as I finish breakfast).

There's lots of pressure to focus and do well on your main project, sure. But it's not external pressure, it's internal pressure. Everyone wants their software to be great. It's hard to detach for a day, ignore the influx of bugs and emails, switch gears, and work on something completely different. Most engineers don't want to spend the mental overhead.

But speaking from experience, when you do choose that path you get nothing but support.

After getting a PhD in (non-CS) engineering and a boring office job, I became somewhat enamored with the idea of Google's 20% time allowance and its apparent spirit of innovation. It led me recently to begin investing my free time in learning the foundations of CS properly. While this effort could lead me down different paths, in the back of my mind, I always thought it would be really cool to land a job at Google. That possibility, whatever its likelihood, has motivated me.

So in some sense, this comes as depressing news.

But not really, because another company will take its place, and I can set my sights there.

For what it's worth, I had a friend who worked at Google a few years ago and asked her about her 20% time. I was extremely underwhelmed, as it sounded like the exact same project she was working on from day to day. My idea of 20% time was always this really creative unbounded time to pursue ideas and things that are interesting to you, but for her it really just sounded like a logical extension of what she was already doing. It was just weird, given all of the projects in all of Google, with all sorts of interests, why would she just focus on the things she was already doing?

I know it'd be impossible to know these stats, but it'd be interesting to see how many (recent) ex-Googlers went on to start their own successful startup. With that, it'd also be quite interesting to speculate how many of these business ideas could have benefited by being "within" Google.

In many ways it's a shame, although I think most of us can appreciate that the Google of yesterday is a different beast to the Google of today. One area where I think it could really hurt Google is in recruitment. I imagine the "20% rule" would have been a huge factor in getting the best engineers to work at Google. With this news, I can see some of the magic of Google disappearing in my mind.

I know a few people who have worked there over the years and they confirmed the same thing - albeit with a huge caveat.

The two people I know said the 20% was a way for their brains to take a break and think creatively. Nothing was too crazy or far fetched not to try out. They said it helped combat the crazy hours and working from dusk till dawn. In short, it helped prevent burnout. I would be willing to bet the turnover rate will start increase as their employees start to work more hours, without any breaks, and nothing to give them something to look forward to and burnout starts to settle in much faster.

Sure, it's not going to make them go bankrupt, but it will have a real world cost to their bottom line.

I've always wondered if one day a week was the optimum use of 20% time, given the need for extended concentration and flow to do really good work in software development.

Google has had some success with it obviously, but I wonder how it would have worked had they done it by Quarter or semi-annually instead.

Say, you meet a certain threshold in your performance review, you get a lump sum of ~20% of the time period that the review covers.

Say for a quarterly review, if you meet the threshold, you get 2.6 weeks. Or semi-annually you get 5.2 weeks, straight. You have to be at the office, but you can work on your own project during that time.

5.2 weeks is some serious hacking time, enabling a great deal of extended focus. Highly productive Google engineers could probably bootstrap a startup MVP in that time, except of course Google would own it.

First, I was sort of annoyed that I had to "sign in" in order to read public statements from former employees about the "20% time" being dead at Google. Beyond that, I think few companies exists that just want to make great products and know that eventually the money will come. In the meantime, most companies are there to make money and if the numbers show that people are more productive working 100% of their time on responsibilities rather than innovation, then who can blame them - they want to make money. However, this is Google, a mega company making tons! of money, so I expect them to encourage innovation. In fact, someone I know recently interviewed there and the "20% time" for side projects is something they seem proud to promote, so can it really be dead? I think the issue may be in the managers/company EXPECTING results out of this time investment, rather than seeing it as a way to encouraging innovation that won't necessary lead to a Gmail or Talk.

But....while I have the type of mind that does very well pulling in disparate ideas and melding them together, I have found that a lot of the other engineers, even the very smart ones, are not always good at invention. I can imagine that Google, has possibly found a way to identify the best group to allow the extra free time, rather than allowing it to everyone. Ideally, if they gave 75 to 100% freedom to the 1 to 5% that have the "gene" of true creativity, they will be better off.

I think that due to new focus on google+ the company is now less able to adopt new projects, if the new idea does not originate from project management. With google+ all features have to be integrated, so simply there is also less incentive/room for innovation; things that stand out of the google+ user experience must be cut for the sake of consistency;

This tendency is self enforcing: If there is less opportunity for the side project to make it then developers will be less inclined to follow through with the idea.

So as an outside observer I can identify a cycle: less room for innovation breeds less incentive for an individual to come up with initiative. Management sees that its liberalism is besides the point, so free room for initiative is scrapped.

Maybe google can still keep on to a culture of innovation in areas of infrastructure and research, but in a wider sense google+ probably did them in.

Maybe that is the right thing to do: they have enough money to buy any start-up if it looks promising. I don't know which one is more cost effective: exploring ideas in-house or buying out start-ups; however if Google looks like any other ordinary shop then it will be less able to attract top talent. I would guess that the free food is not the winning perk that attracts developers.

I get praise and appreciation, and bonuses from other teams. I think it looks good on a resume, I learned something, and it builds a connection across teams. I know the things I'm doing are helping Google as a whole.

People are always going to have different feelings, and often mixed feelings, about putting time into a side project rather than concentrating on their main thing or doing something away from the computer. For me it comes and goes: some days I want a change and sometimes I feel too busy.

This always happens when large companies assert more control in the form of analytic analysis on the productivity of virtually everything. When you are building a pipeline which must be efficient, analytic analysis / statistical analysis plays a huge role in improving efficiency, but it's also a stifling factor when it pertains to the creativity of new solutions.

Google previously focused more on the creativity of new better solutions to an array of different verticals. Now they are focusing on the creativity of their own "super-man-team" instead of the "our peoples make crazy stuff, we hire amazing people" and let them go at it in their spare time and build innovative projects.

Maybe this time marks a period in Google's future where they stop innovating in a disruptive fashion.

20% time helps bring in the "entrepreneurial" types of engineers that Google seeks to hire and as it starts to disappear, they might see fewer of those hires and more of those engineers leaving. Perhaps it's simply because Google has grown to the size where it can take on really big innovative projects (Google X) instead of the respectively smaller projects that were created under 20% time. They've found that they can't have both without hurting their bottom line, so they've decided to go after the big projects. It's a significant shift, but in the end, it could be good for all of us because many have the resources to go after the small and medium wins, but only a few can go after the really big wins.

Lots of the discussion below focusses on the merits of MBAs, upper management, etc. - and while that is good discussion, I just want to add that the killing of this policy - if valid - is yet another example of our flawed practice of capitalism. Capitalism was never meant to destroy creativity nor innovation nor people - but our use of it does lead to those inevitability because of our worst human trait - GREED. Gecko was indeed wrong - GREED is not good - drive is - and they are not the same thing. We need to sharply change how we practice capitalism and develop, into all of our financial models, factors both for total cost impact (i.e. environment, people, etc.) as well as innovation. Current economic models in use do not look at these critical aspect of our existence and until they do, we're all screwed. Innovation and drive are what have brought humanity to this most amazing place in history - not cash (especially fiat cash) and not the hoarding of resources.

I dare the management at Google to reverse course and allow their brilliant stable of top talent to keep the 20% perk - let a few Benjamins go for the sake of building awesome shtuff ("h" intended).

I've heard the exact opposite from VC's -- fact is, the engineer or product founder might be bringing way more value to the table than the business guy. Or sometimes it's vice-versa.

And that "unfairness" in an initial even stock split will come back to haunt the company, since certain founders are not being rewarded justly for their contributions, and will come to resent it later. And that VC investment can be contingent on founders adjusting their ownership stakes beforehand to match the reality of what each founder is actually bringing to the table.

Lesson #58: Don't always believe your own BS.

There is some good stuff in here, but it's not all right all of the time. The part about firing people is interesting. Maybe there is friction because the manager/CEO is doing something wrong and the employee is merely agitating to make things better for the business? The ability to self-evaluate and take criticism/recognize the difference between "difficult" employees and employees who are trying to fix things you are doing wrong seems important and missing from the "people" section.

A lot of these resonate with me... to the extent that I already believe them. It's tough to absorb these sorts of generalities though, which is why startups make the same mistakes over and over again... not because they haven't heard the advice, but because it's hard to apply. I'd love to see, over the next 57 weeks, the author take one of these per week and tell a real story about how he learned it. An example: "Your authority as CEO is earned... don't try to use authority you didn't earn." When did you learn this? You certainly didn't think before "I should use authority that I haven't earned." So how did it stand in your head before, and what experience made you rethink it? Overall, I love stories that give me more concretes to absorb into my understanding of cause and effect, and details that I can use to bolster my understanding of the pithy advice. Thanks for sharing your hard-won experience, and I look forward to more posts in the future.

> If it doesnt augment the human condition for a huge number of people in a meaningful way, its not worth doing.

this is the kind of arrogance i find disheartening about these kinds of lists. really - things aren't worth doing unless they clear this impossibly ambitious bar?

should i tell the owner of the corner cafe i stop into after work every other day, and that gives me a huge amount of joy nearly every time, that she should give it up because her business doesn't "augment the human condition for a huge number of people"? how about the guy who wrote the $5 clipboard app that makes my life much easier? i'm sure he has lots of customers but "a huge number" that have "augmented" their humanity because of his clipboards....

and i hate to be an ass, but ... under whose criteria does rethinkdb qualify for this, anyway? how meta do we have to go here? how many degrees of separation are we talking about exactly?

the problem with these kinds of statements is they can be rationalized by smart people into all sorts of justifications for doing and/or not doing a huge number of things.

Good list. From my point of view, it's also a good source of questions for an employee to ask the founders when interviewing at a startup .

I don't get this, though:

> Watch Jiro Dreams of Sushi, then do marketing that way. Pick a small set of tasks, do them consistently, and get better every day.

How is that marketing? That's getting good at your craft and improving your product.

I watched the movie, but I'm not sure that Jiro is good at marketing. Apparently he's very good at making sushi, but it seems he became successful (and later world famous) despite being bad at marketing.

Incidentally, his shop's average ratings at Tabelog (one of the biggest Japanese gourmet websites) is only 3.8 out of 5, with quite a few "bad" reviews.

I worked as the first employee at a now successful start up. They were 5 founders with each 20% of the shares.

If you cant get to ramen profitability with a team of 2 4 within six months to a year, somethings wrong.

That probably makes perfect sense for some random SaaS app or consumer facing app, but for an enterprise startup, I'll argue that it's off the mark. Just doing market research, a few rounds of customer development interviews, and building the product out to prototype phase could burn up the better part of a year, and enterprise sales cycles are often slloooooowwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww.........

Pick the initial team very carefully. Everyone should be pleasant to work with, have at least one skill relevant to the business theyre spectacular at, be extremely effective and pragmatic. Everyone should have product sense and a shared vision for the product and the company.

That's one of those things that is on every one of these lists, and for good reason. But, by the same token, you could spend the rest of your life looking for the "perfect" co-founding team, never build a god-damned thing, and die peacefully in your sleep, of old age, at 97. By the same token that "good is the enemy of great", one has to realize that "perfect is the enemy of good enough".

That said, I worked alone for quite some time before inviting anyone else to join up, because this does matter. But you can't wait indefinitely... in the real world, the environment around you is changing, and windows (of opportunity) come and go. You could easily miss one trying too hard to find the ideal co-founder(s).

That statement is misleading. It's not an "or" situation. You need to market to both your existing users and your prospects (users or customers). You can't just rely on viral and word of mouth for growth. Yup, good marketing is not easy- you need to figure out your segmentation and reach your prospects cleverly.

Today, I'm releasing my product's 3rd alpha version for testers and then leaving for a small break. My main goal will be to read the two books that are waiting for me for a long time and, to the extent possible, NOT think about anything work related.

The problem with "rules" is that they live in an ideal world, not the real world. "Give up only 15% of your company" sure, if you are the next Google, but even then every raise they did wasn't perfect. Let's be honest there is an ideal way you would build a company, but it doesn't exist for anybody. Startups are hard and messy. You do the best you can, but you can't just know in advance you're picking the best idea, the best people and fundraising quickly. It's not like that at all.

I take issue with a lot of these, but a bunch of other commenters have covered most of them.

This:

>"Assume the market is efficient and valuable ideas will be discovered by multiple teams nearly instantaneously."

That's just irresponsible and unrealistic advice.

Splitting stock evenly and governing yourself as a "final say" CEO seems a bit self-contradictory, to say nothing of whether or not you should be a "final say" CEO in a startup (debatable).

This is also deplorable:

>"If it doesnt augment the human condition for a huge number of people in a meaningful way, its not worth doing."

Yeah, it's wonderful to "augment the human condition...", but don't be a condescending prick about it. Things are perfectly worth doing even if they don't impact a large number of people.

The trouble with this is, Slava inherently claims superiority to his audience when he declares (not suggest, declares) that things are not worth doing just because they aren't up to his self-defined standard of ambition.

Such a statement is not for him to make; it wouldn't sound right coming straight out of one of Paul Graham's essays, so on what authority does he get to make this statement?

I recently switched from Ubuntu to Debian, and I keep wondering to myself why I didn't switch much sooner.

The lack of any integration with a specific desktop environment, and having pure GNU and Linux underneath a pure DE is something that is really quite satisfying. It gives you modularity and customizability without having anything break or feel out of place; something that often happened to me while switching DEs in Ubuntu.

It really has been the benchmark for all free software so far. And the Toy-Story themed releases are a nice touch.

Happy birthday, Debian.

Debian was my first linux distribution. It took me perhaps a week to download the 7 CDs for Woody (I don't think many of them ever actually got used). I was only 12 and really didn't have a clue what I was doing. My main memories are probably more of frustration than enlightenment... However, as the basis of Knoppix (the first linux distribution that I had much success with) it was a huge pillar in my (and no doubt many others') Linux education. The work put in by the maintainers has had a fantastic knock on effect and provides the basis for so much of the internet infrastructure. It's a brilliant project!

My first experience with Linux came after downloading Slackware's "A" and "N" sets and writing the images to 5.25" floppy disks. Somehow, this complete "n00b" managed to get Linux installed and get the machine connected to the Internet via dial-up (which was quite a chore back then).

A few weeks later, a handful of people I chatted with on IRC encouraged me to get rid of Slackware and install Debian, so I did. It was a huge learning curve and certainly not the best choice of distribution for a new user but I'm glad I stuck with it. I was forced how to do everything from a command prompt and reading TFM wasn't an option at the time, it was a requirement.

In the 17 years since, I have never regretted my decision. There was a short period where the internal politics became overwhelming and I almost switched, but I told myself to hold off. I am glad I did.

I'm a big fan of OS X and I've flirted with other distributions over the years but I always come back to Debian for my personal machines. In a large environment I actually prefer another distribution but Debian will always be my true love.

I extend thanks to anyone who has been involved in the project over the years and helped move it forward. I owe all of you a beer.

dictum 1 day ago 3 replies      
Really interesting as an experiment in industrial design and a conversation piece. As a viable product, I have some doubt: anecdotally, when I see people printing documents, they're in something of a hurry, and keeping the pile of paper sheets aligned would be hard. If you slightly knock the printer while using it, the stack of paper may tilt to a side. And having to keep the papers aligned would become an annoyance similar to the PC LOAD LETTER of yore. Handling A4 and Letter sizes at the same time may not be possible. I don't know how being exposed in a pile would affect the humidity of the paper...

I like how it makes me think of printing as a computing process, paper as input and printed page as output, but instead of feeding the machine with input, you "feed" the input with a machine and it gives you the output. If you extend the thought, it's as if the machine disappears, and paper (the input) is processing and then outputting (printed page) itself.

So based on this design concept I have to assume that they expect this printer to run on either batteries or wireless power of some sort.

It seems like a copout.

detharonil 1 day ago 1 reply      
It seems as though a more practical (though perhaps more dust-prone, when empty) design would do this partially upside-down. Rather than allowing the printer to move downward though the paper, why not load the paper from the top?

One could set a full stack atop something similar to his current design using the rollers, and the finished pages could exit through the front in order to prevent them from building up below. The final roller could simply be removed and a slit added to the front such that the finished paper could exit the printer cleanly. A solid plastic sheet could then be added to catch the printed paper which folds back atop the body of the printer when it is being transported or simply not in use, perhaps to prevent the aforementioned build-up of dust.

This accomplishes Yamamoto's goal of removing the paper tray and simplifying as well as shrinking the design while avoiding the dangerous consequences of brushing past the printer while it is atop a high stack of paper.

Of course, none of this addresses a central flaw with his design. Even if two models are produced for Letter and A4 paper, there are still many other sizes in use, and there appears to be no easy way to adjust the sizes of the intake and output areas without the dreaded paper tray.

First, I'd like to point out that his suggestion is fucking absurd. Without codes, there would be no way to discern between methods of customer acquisition (eg. is this ad more effective than that ad), especially on non-web content. Moreover, the efficacy of customer acquisition would decrease tremendously (most people respond to ads because of the promise of a discount). I don't understand how the OP believes that this is financially tenable for most sites. Codes are a fundamental aspect of advertising strategy for many companies.

Second, the notion that this is hostile to the user just bemuses me. I don't understand why this has any detrimental effects on the customer. If they are fine paying full price (as they were when they began checking out), they are free to pay full price. If someone with expendable free time would rather dig through these coupon sites, that is their prerogative. The existence of a coupon code field merely gives the option to seek out a discount. This is similar to most other forms of commerce. If I have free time and want to save money, I can dig through circulars and clip ads, or I can just go to the store and pay full price. Is it offensive to the user that the self checkout also has a slot for placing coupons? No one is forcing anyone to do anything. How is it bad customer service when a user literally isn't forced to do anything other than ignore the field if they so choose? Giving people the option to save money if they are willing to exert some effort is an unequivocal positive aspect of most sites.

This piece is just incoherent to me. I honestly don't understand why this is bad in any way.

I dropped my car off for state inspection by my usual mechanic. Then I found a coupon in the local paper for $10 off an inspection at that place. When I went to pay, I showed the coupon but the mechanic told me, "oh I already did that. You're a regular, we take care of you!" I don't think I've ever seen a website that could do that.

This is a pretty ridiculous complaint.

First of all, giving everyone a referral URL works great in a web only world but what if you're advertising on a Podcast (or gasp print or radio), is it easier to tell people to type in www.mysite.com/coupon to their browser or is it easier to tell people to enter COUPON at checkout?

Secondly, the amount of people who are going to have this adverse reaction to the mere existence of the coupon code field is vanishingly small. Most customers who don't have a code will just ignore it and move on (and actually many who have been told about a code will not even use it) only a small minority will bother searching for a code to enter when they don't have one.

Whatever web site had a coupon code field that made you this angry probably had at least 20 much worse UI violations they should prioritize above trying to eliminate the coupon field.

"You get pages of results: mostly garbage, some scams, and a few legitimate coupon sites. Unfortunately, the codes listed on those sites are a year old: you missed your chance."

It frustrates me when I see a coupon code box and cannot find any working codes. Oftentimes the most recent codes for a retailer on RetaiMeNot haven't been active in months or years. On the flip side, when I find a code that saves me anything, even free shipping, I am ecstatic. I feel like I am responsible, thrifty and savvy and I have a proclivity to purchase more items from that retailer later on.

I think these emotions are worth evoking in customers and banning the coupon code box destroys this ability. A referral link doesn't capture as much of the emotional satisfaction as seeing your cart totals drop after typing in a string of characters and clicking "Apply to Cart." Retailers could just hide the coupon code box when there aren't any active coupons. When a coupon is active, the box reappears.

I've seen cases where having a coupon code actually increased conversions more than just discounting the product for everyone. The people who searched for the (easily found) coupon were far more likely to completely the purchase process because they felt like they were getting a deal.

If you're using voucher codes you shouldn't just use one approach based upon an article like this, rather you should be A/B testing different variants and see what performs for your startup. Your customers aren't the same as everyone else and you shouldn't expect them to behave the same.

Lenovo does this, but they quote all the prices assuming you are going to put in the coupon code, which they display on the entry page into the product you are buying.

If you don't realize you have to jump through this dumb hoop and think you are actually getting the discount automatically, which is quite easy to do (I did, and I'm no dummy), they do not reimburse you the difference if you call on the phone to explain. The guy on the phone specifically explained to me that that is their official policy in this situation.

I mean, I trusted Lenovo (good past experiences), so I wasn't being super duper careful to look for any kind of trick. Imagine that... not looking out for being tricked! What a fool I was.

If you eally want the discount, you have to cancel your order and re-order, which means getting the product later. Lenovo knows very well that many customers won't do this.

tl;dr Lenovo suits have calculated a new way to trick customers, and treat customers in a shitty way. They should be ashamed. Gipped me off for a few hundred bucks.

Why do web apps and retailers do this to their paying customers?

Because it was a pain to manage millions of coupon codes on legacy catalog fulfillment systems. In fact, it's still not particularly easy.

Way back in the day, mail order retailers would send out millions of catalogs to current and prospective customers. To get these people to order, they would include coupons as an incentive. The coupons generally involved a short code indicating the mailing and a number indicating a segment. So, you'd get something like SU95615, which would translate to Spring 1995 segment 615. Segment 615 could be part of your own list or it might be part of a list you were renting. When the orders came in the codes would be used to tie back the promotional mailing spend to the revenue, thus allowing the retailer to score a list or segment.

So why not use individual codes and then roll up? More sophisticated companies did that. In fact, some would even have SKUs that had prefixes tied to the mailing allowing for some very deep analysis. However, most did not and it was primarily due to the fact that their systems were not designed to handle such customization. In fact, some would basically choke on that much data.

When these companies moved online, they took the practice of using coupon codes right along with them. As new companies without the legacy issues came along, they adopted the old ways and the cycle continued.

This is why these companies do this to their customers. Is it right? Of course not, but that's the way it is.

That said, there are better ways to handle this need to promote and track marketing dollars. Lots and lots of ways.

Here are a few I've tried. Each one works pretty well:

1. Using specific links in email promotions with codes already embedded: This is probably the best way to go. Customer get the code applied. No need to show the field at all. This is great for targeted promotions.

2. Using business logic to apply a discount automatically: In this scenario, there is no codebox either. The system figures out the right discount based on the promotion. This is good if you're giving account-based promotions or doing something site wide.

3. Single-use, unique codes: This is a special code that can only be used once (ideally by a specific person). This method has the added benefit of being a marketing tool in and of itself (i.e. you can tell the customer they are special because the code is made special just for them). Great for email and print catalogs.

In each case, there was a measured conversion improvement. In some cases, it was quite significant. However, I would strongly recommend testing. You're at the bottom of the conversion funnel here; caution is advised.

You may discover, as JC Penney did, that your customer base has certain expectations and that changing those learned behaviors is more difficult than you might expect. You may find that removing the coupon field generates more customer service requests (i.e. "Where do I put in my coupon?") You may also discover that your marketing department has no clue about how to tie your ingenious solution back into their demand generation. You may also discover that your systems are not well-suited to carrying so much additional data.

It's complicated but from my experience I'd have to say it's worth the effort to solve. Not only will your customers have a better experience, but you'll have better data about those customers and the sources you're tapping to bring new ones in the door.

Of course, be prepared for lots of complaints from the coupon stackers. Those guys really don't like it when you remove the field.

Coupons are a form of market segmentation, which generally aims to extract surplus money from those customers who will pay more (for whatever reason - don't care, don't know any better) while still extracting some money from those who are price-sensitive.

This comes at a cost though, see this classic by Joel Spolsky: http://www.joelonsoftware.com/articles/CamelsandRubberDuckie...

The cost is the trust and goodwill of your customers. People will feel cheated if they find out and hopefully leave you for a competitor who doesn't impose on them the additional mental cost of searching for coupons, finding price engine links with lower prices(#) or whatever.

(#) Some shops actually do that - you get a better price from a price comparison engine than if you search from shop's own site. Talk about treating your trusted customers well.

This may not be rational, but there's some research showing this is a widespread phenomenon. Mostly, it has to do with a sense of fairness. Coupon codes can make consumers feel like the merchant is being unfair, which leads to dissatisfaction.

The solution: don't show the coupon code field or make it extremely easy for consumers to get coupon codes. I've noticed more and more stores put their coupon codes right in the header while you're browsing. So it's impossible NOT to get a coupon.

I think these coupon codes produce this reaction because they remind us how non-transparent online commerce can be.

Walmart has a hard time at their brick and mortar store charging more for diapers to the poor person who lives down the street and has no car to get to competitors, and less to the better off person who arrived by car. But a huge amount of "big data" work is spent differentially pricing online commerce -- the travel industry is most famous for it of course.

The general trend of technology tends to be that tools once only available to the big institutions become democratized and more revolutionary as they are. Similarly I think the "big data" and tracking and etc will swing around into a more equitable balance.

That can be hard to believe, but try to imagine this -- you go to buy something online, but you pay with bitcoin, and a browser plugin you have pops up a screen when you are on the final checkout page -- this plugin uses the bitcoin chains and non-anonymity to show you all recent transactions with that bitcoin address. You can then get an instant sense of whether you are overpaying or getting a deal.

Such a system could be gamed and evaded of course.

At one time I discussed making a reverse-Priceline system, where consumers would use a browser plugin that shared what offers were being accepted and rejected on Priceline style reverse auctions.

The sum total such efforts is a lot of infrastructure invested in replecating what a simple open-outcry market would be, if the market were run by disinterested, trusted authority.

Sometimes when I'm buying online, it does bother me to find that "other" people have a coupon for something I want and that if I REALLY want it, I will need to pay full price. It specially bothers me when I'm a returning costumer and didn't receive any e-mails letting me know of a sale or coupon. This situation applies to other situation as well, for instance, think about the couple (or single person) that signed a contract to rent a place, has been a great tenant, and would like to renew the contract that is now ending soon. However, instead of the landlord saying: "hey! you have been a great tenant, so I will NOT raise your rent (or as much), so I can keep your business for longer", he/she says (thinks): "I know you like it here, so I'm going to stick it to you and raise the price of the rent, while new people who I don't even know, will get a cheaper rate and possibly not be as good a tenant as you are".

Sites should definitely keep track of loyal costumers and offer coupons in this manner and allow one to enter then once logged in, but not trouble visiting costumers with this. Letting people know they could have gotten something for cheaper is usually a discouragement from click the "place order" button. I know have definitely just x-ed out of my tab at that point in several occasions.

Outside of ad campaigns, there's another case where coupon codes are useful. If you have a moderately expensive product and an actual sales team, you can use the coupon field to let the sales team make one-off special deals for individual customers. That's useful for unusually large orders (buy 10 get 1 free) or simply if you need to apologize for some sort of error (we're sorry our site was down, here's $50 off your next order).

Coupon codes are an easily programmable solution to a wide variety of business problems. They're particularly useful for problems that are difficult to predict in advance.

An alternative approach would be to create a 'claim coupon' form and point your couponeers to that so that they may redeem the coupon. The trickier part would be then to keep track of the coupons in a similar fashion to the 'Items in Cart' (either via session based tracking or link it to their account).

This approach would also allow for implementing coupons in different ways (ex. time-based, limited), reduce mental stress by being able to retry codes till you found a valid coupon (some providers allow for coupon codes but no way to verify it's valid) and not distract from the check-out process (it would simply require showing which of the redeemed coupons are applicable to the purchase).

A plus side of this approach is that a coupon is enough to persuade potential buyers to create accounts to keep their coupon (while it's valid - for later use) and thus also reducing friction in the check-out process which should lead to more sales.

I do also now believe the existing 'coupon' implementation is at fault by leaving too much on the table.

I'm sure it's just me, but I've never felt bad or weird or bad or even cared much about the possibility of paying 20 bucks for something vs 19 bucks with a 5% off coupon code. That one dollar savings doesn't seem worth the hassle of spending 20 minutes on Google. I'd rather spend that 20 minutes billing 100 bucks/hour making a website for someone.

Reading these comments it seems there are a lot of people on Hacker News who seem quite passionate about the idea of getting the best deal they can and not "feeling like a sucker".

Which is fine, but it's definitely a feeling I don't experience. Maybe I'm just weird.

With the topic at hand, having maintained an online shop for a client for several years, I see that they use Coupon Codes as a customer service thing. Didn't like your product?

Although I understand the anger stemming from coupon code forms, a lot of us use them for very different reasons:

- I run http://DayOnePP.com and sell my inventions there.

- When something goes wrong for a customer you can give the customer a coupon code "sorrykarenhurney" which will give them free shipping or 10% off. This is a great way to win back customers who have had trouble. (You can rename the "Coupon Code" field to be "Customer Service Code" if you use it exclusively for this purpose)

- When I advertise my Calendars or Pens on a design blog I tell the owner that I'll give them an exclusive discount to their readers if they mention my product on the front page. I name the coupon code after the website.

- You can email coupon codes to newsletter members as a reward for signing up for your newsletter.

Although the OP has a legitimate concern, he has never run an online store and doesn't see the behind-the-scenes logic in selectively giving customers discounts. It really is a necessity. Brick & Mortar stores use them even more, but no one gets pissed off at them.

As long as these NSA activities are not dismantled and the People do not have transparency over what the NSA/government does, everyone of us can still be "eliminated" by the push of a few buttons and democracy therefor no longer exists.

Even if its decline happens slowly and behind our backs (https://en.wikipedia.org/wiki/Boiling_frog).

You can also use ranger [1] to change directories, especially if you want to explore the directory tree quickly when you don't know exactly where to jump to. Install it and add the following to ~/.bashrc:

     function ranger-cd {       tempfile='/tmp/chosendir'       /usr/bin/ranger --choosedir="$tempfile" "${@:-$(pwd)}"       test -f "$tempfile" &&       if [ "$(cat -- "$tempfile")" != "$(echo -n `pwd`)" ]; then         cd -- "$(cat "$tempfile")"       fi       rm -f -- "$tempfile"     }     # This binds Ctrl-O to ranger-cd:     bind '"\C-o":"ranger-cd\C-m"'
(This script comes from the man page for ranger(1).)

Edit: Modified the above script for use with zsh (and multiple users):

     ranger-cd() {       tempfile=$(mktemp)       ranger --choosedir="$tempfile" "${@:-$(pwd)}" < $TTY       test -f "$tempfile" &&       if [ "$(cat -- "$tempfile")" != "$(echo -n `pwd`)" ]; then         cd -- "$(cat "$tempfile")"       fi       rm -f -- "$tempfile"     }     # This binds Ctrl-O to ranger-cd:     zle -N ranger-cd     bindkey '^o' ranger-cd

I set my version up with a -f on the unmark rm so that I don't need to be prompted to remove it. Also added some basic completion for both jump and unmark

  export MARKPATH=$HOME/.marks  function jump {       cd -P $MARKPATH/$1 2>/dev/null || echo "No such mark: $1"  }  function mark {       mkdir -p $MARKPATH; ln -s $(pwd) $MARKPATH/$1  }  function unmark {       rm -if $MARKPATH/$1   }  function marks {      ls -l $MARKPATH | sed 's/  / /g' | cut -d' ' -f9- | sed 's/ -/\t-/g' && echo  }  _completemarks() {      local curw=${COMP_WORDS[COMP_CWORD]}      local wordlist=$(find $MARKPATH -type l -printf "%f\n")      COMPREPLY=($(compgen -W '${wordlist[@]}' -- "$curw"))      return 0  }  complete -F _completemarks jump unmark

To have completion with bash you can use this:

  function _jump {      local cur=${COMP_WORDS[COMP_CWORD]}      local marks=$(find $MARKPATH -type l -printf "%f\n")      COMPREPLY=($(compgen -W '${marks[@]}' -- "$cur"))      return 0  }  complete -o default -o nospace -F _jump jump
Bash completion really needs better docs :-|

I have no idea if anyone else does this, but I use tmux a lot for different projects. I usually have vim in one tab, logs in another, and tests in another. However, each tab I open I need to cd into the same directory. As such I came up with this helper for zsh. Every time I change a directory it records it. When I start a new session (new tmux or iTerm tab) it goes straight to that directory:

    # record directory in ~/.lastpwd    record_pwd() {      pwd > ~/.lastpwd    }    chpwd_functions=(record_pwd)        # go to last directory when opening a new shell    if [[ -d `cat ~/.lastpwd` ]]; then      cd `cat ~/.lastpwd`    fi
For other shells that don't have something like chpwd_functions you could just alias cd.

I've been using the following in some form for over 3 decades!(now in zsh)

    alias   .=cd
In /bin/sh "." sources a script. While this can be common in a script, one rarely does this interactively so I usurped . for the most common operation!

    alias   ,=pushd    alias   ,,=popd    alias   ,.=dirs
Think of cd as a goto, pushd as a call, popd as a return and dirs as a stack trace!

    ..() { cd ../$* }    cdpath=(. .. ~/src ~)
Use of cdpath can be confusing so it is best to show part of $PWD in the prompt:

    PS1="%* %5. %h%(#.#.:) "
This ends the prompt with a # if you are running as superuser.

These aliases/functions are enabled in .zshrc (only if run interactively -- that is, they are included below the following test):

    if [[ ! -o interactive ]] ; then return; fi
The "benefit" of Jeroen's mark/unmark is that these paths persist (and can be used from any window running a shell. I have not found much need for that + I can have different $dirs in different windows. Also, given that my shell windows (under screen) persist for a very long time, I don't need symlink's persistence!

Alternatively I define "." to be a function that does arg specific operation (cd if a dir, acroread if .pdf, vi if text etc.).

This is great, but I don't see why this is better than autojump.

* Autojump automatically saves marks,

~~~cd Downloads # And you are done.~~~

* You don't have to think about mark names,

~~~cd Projects/Python # It will be called `python`.~~~

* You don't need to remember mark names,

~~~j haskell # If you want `Projects/Haskell`, odds are the mark is auto-named `haskell`.~~~

* You can specify only some part of mark name;

~~~j bar # And you are in `Stuff/foobar`.~~~

Other than that, this is, as I said before, great! Looking forward to go through the source code to learn more about Bash.

cool! I'm a command-line junkie as well.So, I've been doing something similar for quite a while.

Here's what I have done :

    function ccb ()    {        FOO=`pwd`;            echo >> ~/shortcuts.sh;            echo alias $1=\'pushd $FOO\' >> ~/shortcuts.sh;            echo >> ~/shortcuts.sh;            . ~/shortcuts.sh        }
simple but quite effective.

Now, all I have to do is type ccb and give a shortcut name to register a shortcut. Then whenever i want to jump to that directory, I just have to type the shortcut.

Eg :

    foo@bar deeply-nested-dir# ccb deepd    foo@bar deeply-nested-dir# cd    foo@bar ~# deepd    foo@bar deeply-nested-dir#
My method lacks the a) delete shortcut and b) list shortcut features that the above solution gives, though.

This is a very informative thread for people trying to streamline their daily shell experience. I'm looking forward to experimenting with the utilities mentioned here. I spend a significant amount of time in, and moving between CVS sandboxes. All my sandboxes have the same internal directory structure, but the root of the path changes. To speed up navigation time I created a tool to replace directory names with aliases. The aliases are persistent. They can also be "stacked", which allows you to specify a sandbox as an alias, then reuse your existing aliases to navigate within the sandbox. Auto-completion in the shell is an excellent companion as well. More information on "stacked.aliases", as well as the source can be found here: https://github.com/ttomaino/stacked_aliases/wiki. I include one example to illustrate:

As an example, the following two sandboxes contain the Broadcom Ethernet driver:

/build/username/sandbox_a/software/vendors/linux/linux-2.6.35.7/drivers/ethernet/broadcom/build/username/sandbox_b/software/vendors/linux/linux-2.6.35.7/drivers/ethernet/broadcom

Use the add alias command aa <alias name> <directory> to create aliases for the sandboxes:

aa a /build/username/sandbox_aaa b /build/username/sandbox_b

Then create an alias for the Broadcom directory:

aa brcm software/vendors/linux/linux-2.6.35.7/drivers/ethernet/broadcom

To change to the Broadcom directory in sandbox_a, just stack the appropriate aliases using the ua command. Stacking is done by stringing the aliases together with a period delimiter:

ua a.brcm

To change to the Broadcom directory in sandbox_b:

ua b.brcm

I just do this (in zsh):

Which automatically pushes (unique) directories I've visted into $dirstack.

Then I have an alias:

    d () {            local dir            select dir in $dirstack                    echo $dir                    break            done            test "x$dir" != x && cd $dir    }
That gives me a list of directories to jump to in my history:

    ~/src/git/emacs-prelude $ d    1) /home/kelvie/tmp/typhoon          3) /home/kelvie/src/git                  2) /home/kelvie/tmp                  4) /home/kelvie                          ?#
So I just type 1-4 to go back to a directory I've previously been in.

A few months ago I had an RSI problem so bad - able to type only a minute at a time, even sitting with hands on keyboard hurt - that I started down this route. This video was, literally, a life-altering motivator for me, and I was quite obsessed with it.

Ironically, after seeing a physical therapist - which, let me tell you, you should do at the first sign of pain, because while they can't help some people I personally am batting 1.000 with PTs for RSI over my many-year career - my recovery is now so complete that I've totally fallen off the voice-computing path... for now. But I intend to keep going, not just because it is hilarious but because, well, RSI happens and it really pays to vary the routine sooner rather than later. There is nothing like trying to do a ton of emergency scripting on Python and emacs at the lowest possible point of your productivity.

The most important hint I have so far is: do not waste time with Mac OS. You need a PC running the Windows version of Dragon. The Mac version is pretty good for occasional email but lousy for emacs because it doesn't have the Python hook into the event loop that a saint hacked into the PC version years ago before leaving Dragon.

The speechcomputing.com forums are your friend.

Yeah, they say there is an open-source recognition engine that works okay, and time spent improving free recognition engines is time that really improves the world for all kinds of injured people, but here's the problem: when you need a speech system you really need it, and there are a lot of moving parts. Dragon, and Windows, and a super PC to run it on are super cheap compared to your time, especially when your time is in six-minute increments punctuated by pain.

Tangentially related, but I'll throw it in here, since so many developers aren't taking ergonomics seriously. RSI can happen to you if you are not careful, and it can wreck your career (almost happened to me). Several years ago, I started having aches in my arms. Over half a year it got gradually worse, until it was so bad, I thought I had to give up coding altogether. Fortunately, I managed to get it under control, mostly with the aid of a break program, and an ergonomic keyboard and mouse. I'm now completely over it, but I still need to be careful not to get it back. A lot more details in this post: http://henrikwarne.com/2012/02/18/how-i-beat-rsi/

"Emacs pinkie" is a non-issue if you use a keyboard with thumb clusters, e.g a Maltron or a Kinesis model. Investing in a good keyboard is just as crucial as investing in a good chair, especially if you make a living by coding. The time that you spend compensating for a bad input device by hacking your own workarounds can be more costly then spending money on a proper solution.

Once you are an adequate touch typist typing speed is only beneficial if you use a language that requires you to type a lot of boilerplate. Even then, you can use an IDE for auto-completion. I can type at very high speeds as fast as others can input text by using their voice but I can't remember the last time I needed to type for more than a minute at a time. If you use a language that requires you to spend more time thinking about code than it does to actually type it, typing speed really doesn't matter. Code is like speech in that it is judged by the eloquence, not the speed, of its delivery.

My counter-argument to voice-driven coding has been primarily around the input bandwidth and the fact that you must work from home with that kind of setup.

I guess the presenter conducted the "faster than the keyboard" test under very controlled circumstances (e.g. only working on his own code, so one doesn't have to deal with non-english-word variables/functions).

I don't mean to be a hater, because that was an _amazing_ demo, but I don't believe it's the holy grail the title implies it is.

For the couple of minutes I watched of him demoing it... I type waaaay faster than that. In fact, I can't possibly imagine how I could speak faster than I can code on the keyboard.

(Regular English sentences are another story, but code is full of important punctuation, exact cursor positioning, single characters, etc...)

I mean, this is awesome for people with trouble typing (which was my own case a few months back), but I don't think it needs to be over-sold by being "better"...

I promised to release my duct tape code later this year. I'm a bit behind schedule with that but it should be out in a month or two.

Whenever I see posts about voice controlling your computer, I spontaneously think "thank the heavens I don't have to share an office with you." I realize some people work alone, at home or in a sound proof office, but every work environment I've worked in has had a shared acoustic space.

These voice control schemes almost always end up as a cool gimmick, and rarely as a productivity boosting solution.

Question (halfway on topic) --

Who makes the best speech recognition software in the world? Regardless of whether it is available to consumers ... who is the best at it?

In particular, how do Apple (Siri) and Google (Google Now) compare to Nuance's stuff? Is Nuance so far ahead of everyone else that they're the clear leader? Or is their codebase "legacy" and vulnerable to better, more accurate software which can be built now due to better algorithms and approaches?

What I think is interesting is that a lot can be done to make typing easier and more human when you can type like you speak (and think).

For example: we say/think

  for each item in list
but in a lot of languages you need to type something like

  foreach(item in list) {
A step further: we say/think

  let a be the substring of b from 1 to the end
we need to type

  a = b.substring(1)
Ofcourse the last example is much shorter and even more readable (to the machine for sure) but maybe code could be a little more human.

A word of warning -- I started dictating all of my email and Facebook replies on my Android using Google's voice keyboard on my Nexus One a few years ago in response to RSI pain in my hands from overusing my cell phone. Within a month, I started losing my voice.

RSI comes in multiple forms; using your voice exclusively is not going to fix the problem. The trick is to switch things up, which involves having alternatives in the first place.

This is a cool project, as I think a voice interface would be the ultimate in computing, something like in "2001, A Space Odyssey," or "Star Trek."

I remember first playing with voice recognition and voice command on a PPC Mac back in 1994.

That the technology hasn't progressed along the same lines as cell phones and processors is testament to how difficult voice recognition actually is when dealing with a wide variation of dialect within any given language.

I would love to be able to use my voice as my main input to my computers and other devices.

Here's an open source Python script i wrote a few years ago that allows you to type with your voice. It's based off of CMU Sphinx. The accuracy is almost certainly not as good as Dragon, and it doesn't have a macro facility, so you cannot code as fast as typing. I haven't improved it much over the past few years because my hands got better and i don't need it anymore.

Isn't this a protection-money racket (extortion) from a legal perspective?

http://en.wikipedia.org/wiki/Extortion

http://en.wikipedia.org/wiki/Protection_racket

> "Extortion is a criminal offense of unlawfully obtaining money, property, or services from a person, entity, or institution, through coercion."

> "In the United States, extortion may also be committed as a federal crime across a computer system, phone, by mail or in using any instrument of interstate commerce."

http://www.quickanddirtytips.com/business-career/legal/what-...

> "What is Extortion? The use of threats to extract money from people is a crime in the United States..."

> "Which Kinds of Threats are Illegal? One common characteristic of extortion is the use of threats, that is, an express intention to inflict injury, loss, or some other bad consequence on another person. The threat has to be sufficiently plausible and imminent that it could convince a reasonable person to give in to the blackmailers demands. In addition, there has to be some evidence that the threat was actually made for the purpose of obtaining money or property."

http://www.orbankruptcy.com/newsletters/criminal-law/federal...

> "A person commits the federal offense of extortion if he or she transmits in interstate or foreign commerce any demand or request for ransom or for a reward for the release of a kidnapped person, any threat to kidnap or injure another person, or any threat to injure the property or reputation of another person or to accuse another person of a crime with the intent to extort."

Now that one specifically mentions that threats to injure persons, property or reputation qualify as extortion when done to get money from someone.

Here is the actual federal law:

http://www.law.cornell.edu/uscode/text/18/875

> "Whoever, with intent to extort from any person, firm, association, or corporation, any money or other thing of value, transmits in interstate or foreign commerce any communication containing any threat to injure the property or reputation of the addressee or of another or the reputation of a deceased person or any threat to accuse the addressee or any other person of a crime, shall be fined under this title or imprisoned not more than two years, or both."

It seems very clear that that is what has happened here.

But if this form of threat by a Groupon employee to extract money from people is not extortion, what is the subtle difference that would enable such threats to be considered non-criminal?

This would be better titled "idiot gets himself fired (from Groupon)", since it's unlikely that Groupon has a policy of threatening their customers in writing, or much tolerance of employees who make it appear that they do.

Incidentally, "As a resident of San Francisco for over 25 years" is code for "this is my first job out of college". Hopefully he'll be a little smarter by the time he finds his second.

And this is why there is a high turn over rate in sales, seriously.

The salesguy is clearly over the top aggressive and likely new to the business. He will get let go, if he hasn't been already, and some other person will replace him. If you deal with sales folks you will find the ones who have had the most success in their career seem to push right up to the line and don't cross it. This guy will no doubt re-calibrate and head back in selling windows or something.

I expect it is the nature of sales, you measure someone on their completed sales, period. You don't measure anything else and they will experiment with different ways of maximizing that number, some of them illegal (see the behavior of the Google sales guys in Africa [1] as an example) Businesses fire the ones that generate ill will and keep the ones that don't.

If you mostly export (i.e sell abroad), there are some additional considerations for picking a payment provider (I speak from the point of view of a UK company).

We've been using Shareit for selling software for many, many years and it's basically 4.9% as fees. The first interesting part for me is the currency conversion rate. We operate in GBP and all of our sales last month were in USD. Working out the average rate we got 1.54 USD to 1 GBP. Looking at the exchange rates for July [0] that seems reasonably close to the mid market rate.

I'd be interested to know how Stripe determine their conversion rates. If it's mid-market then we're looking at 4.4% against 4.9%.

The next issue when exporting is whether you have to register formally in the country you're selling to in order to avoid withholding taxes [1]

The countries we've come up against this to date are the USA, Portugal and India. The volume we do with the US justifies registering with the IRS and making a W8-BEN form available to all companies we sell to.

The process for the US is doable and the volume we sell there easily justifies it. The process for Portugal is awful and the process for India comprises about 6-8 weeks of utter bureaucratic bullshit [2]. The sales volume from these countries were not worth going through the process.

If we didn't go through this process and sell directly in these countries the buyer would have to withhold a proportion of the purchase, usually around 20%.

Shareit is an actual reseller, legally. Stripe isn't, AFAIK. So, Shareit can deal with the admin in these countries and pass over the same amount they do as for any country. A few years ago, we hadn't heard of withholding taxes, it's becoming more and more common as countries try to clamp down on tax evasion.

It's more strictly enforced the larger the payment amount gets, but my point is to be aware of the legal differences in payment processing services regarding foreign withholding tax rules.

Edit : There's actually a third issue as well and that's whether your insurance covers you to take card information on your site (up to details regarding the type of SSL certificate you have installed) and, if it does, whether you comply with all the security constraints the policy imposes. You may find that the additional premium is more than the cost savings.

Could someone people explain the appeal of Stripe? The APIs are nice, but so a most other payment providers.

The fee Stripe charges are pretty high. We would never agree to a percentage of the sale, only a fixed price. The fact that you can't change who process you credit card payments (can you?) excludes you from getting any good deals on fees. If you shop around you can save a lot of money.

Honestly getting a merchant account, if that's the excuse for using Stripe, isn't that hard.

When we started Teddle the landscape for payments in the UK looked very very different. At one point PayPal looked like our best option. In reality their product would have killed our business (matching customers with independent house cleaners), with their punitive withholding of funds and lengthy clearing times.

Then Andy and the guys at Stripe UK came along and blew the competition out of the water. They have been doing an outstanding job. The product is ridiculously good, the documentation is awesome and the customer service is human, friendly and reliable. Honestly I can't praise the product enough.

My understanding was that we would need a USD account in the UK in order to charge customers in USD. Have you now fixed that? I can't find anything in the docs? Or are you saying that we can just charge people GBP no matter where in the world they are?

Why is Stripe so interesting? As far as I can tell, they still only offer one payment method, credit cards.

That makes them quite uncompetitive in most countries where credit cards are just one of the many online payment methods, and completely useless in countries where most only payment has already shifted to direct transfers without the cost and hassle of going through credit card companies.

The movement is now towards harmonizing direct payments and mobile payment. Using credit cards for online payment feels so yesterday to me.

Interesting that Braintree went to the whole EU at once while Stripe seems to take it country by country.

Not sure if it's related but at around that time Braintree changed the pricing to add Interchange fee that depends on the card used, service offered etc. Making the final pricing somewhat confusing but maybe more affordable as a result.

Does anyone know if Stripe account setup&approval for UK is just as straightforward as for US? With Braintree they ask for financial (turnover & EBIT) and shareholder information when applying as an EU company, no idea if it's also the case for US companies.

This is both expensive currency conversion; but we also spend $USD so have to pay to turn our GBP back into $USD!

Fix this, and we'd move in a heartbeat.

I would love to use this but the pricing is a bit of a problem. The Visa credit price per transaction is only a little bit higher but almost half our transactions are Visa debit which are charged by our existing provider at a flat rate of 34p + 10p for the gateway. The Stripe cost for a 60 transaction would be 1.64. The pricing needs to take into account the higher rate of debit card usage in the UK.

Seems like a good idea, but the wrong way to achieve it. The right way, as I understand it, would be to write it up as an RFC and submit it to the IETF; and to contribute code for it to some of the popular web servers (apache, nginx, etc). The site doesn't make any mention of either of those things.

Edit: oops, I was wrong. There is an RFC and it's linked from http://www.451unavailable.org/what-is-error-451/

I once worked somewhere where some resources could not be displayed to all clients. We chose to (ab)use HTTP 409 Conflict.

> 10.4.10 409 Conflict

> The request could not be completed due to a conflict with the current state of the resource. This code is only allowed in situations where it is expected that the user might be able to resolve the conflict and resubmit the request. The response body SHOULD include enough

> information for the user to recognize the source of the conflict. Ideally, the response entity would include enough information for the user or user agent to fix the problem; however, that might not be possible and is not required.

> Conflicts are most likely to occur in response to a PUT request. For example, if versioning were being used and the entity being PUT included changes to a resource which conflict with those made by an earlier (third-party) request, the server might use the 409 response to indicate that it can't complete the request. In this case, the response entity would likely contain a list of the differences between the two versions in a format defined by the response Content-Type.

Is this saying:

"As a web user I want our ISPs/governments to give us a nice error page so we understand what is going on when they DNS block or seize websites"

Or is it saying:

"As a web-master, when have to take down content due to legal proceedings I want a nice HTTP code to return"

They give example of the first (Virgin Media), but that takes down an entire domain, so it's kind of irrelevant if the correct HTTP code is returned, it's not like that is going to be resolved quickly. 503 would be the correct code here.

The second might be useful to spiders (who might want to back-off spidering so often for a while), but then wouldn't you just want to show your users a 404 with a nice reason why the content has gone.

There is a lot of discussion below on whether 451 is the right error code and how to implement it properly, but I'm missing one thing - what's the benefit of doing it as a status code at all?

If you're going to say that it raises censorship awareness - Internet protocols are intended as useful technical standards for programs to communicate, not vehicles for political goals.

What is the technical benefit of failing with a different error code? Is there need for client software to react differently to a 451 and a 403? The status code is not intended for the human user. If we want to raise awareness, than we already have means to do that - a 403 with a descriptive page citing the reasons. Many websites already do that when complying to DMCA takedowns.

I can see some reasoning behind this, but the reasoning is that the emphasis of the problem is "people are angry at the site because something is blocked so let's show an error code reflecting the real reason." Using 451 would take the emphasis away from the site and onto the legal oppressor.

On the other hand, why not inverse all inaccessible content to legal oppressors? Change the default meaning of 403 for example to "Access denied for permissive or legal reasons".

There are some great images here. I like how Google has been striving to document more beautiful places. The sheer amount of brainpower and processing that Google is putting into Streetview is truly staggering and unprecedented. Nobody else out there is doing it in this way.

On a more hand-made note, my company, http://360cities.net, has been publishing user-generated 360 imagery since 2006. I have built a tour of my own city, Prague, starting in 2004, which was before Google Maps or Streetview. We now have hundreds of thousands of images, (all high-resolution, completely spherical 360 photos) from every country of the world, including some very remarkable places in Antarctica, skydiving from an airplane, underwater, "remote" places such as Havana, Iran, Tibet, Burma, Easter Island, and so on.

Our "editors' picks" are something I'm really proud of. https://www.360cities.net/search/@tags-editorspicks

here is our world map. zoomed out, you should see only "great" stuff: http://www.360cities.net/map

Other services that are similar to 360cities include http://viewat.org, http://roundus.com, http://arounder.com, http://photosynth.net.

At the same time, I can't help but grin that we on the CS side find a way to erase all the gains in performance and efficiency as soon as the EE guys make them.

There has to be come kind of universal constant: the limit, as technology proceeds into the future, of the execution time of "Hello World" is some fixed number. Because as soon as we get better hardware, we invent an even weightier runtime environment to slap on it. ;)

Note to security response teams everywhere: Not all vulnerability reporters speak perfect English, nor are they all experienced in writing up details on how to exploit issues. It is your responsibility to obtain details from reporters, after the initial report, to avoid situations like this. Facebook should give a bug bounty here, due to their lack of due diligence in following up with the initial responses.

You're being accused of intentionally breaching security, violating copyrights, violating individual privacy by creating the website, www.facemash.com. You're also charged with being in violation of the University's policy on distribution of digitized images. Before we begin with our questioning you're allowed to make a statement. Would you like to do so?

Mark Zuckerberg: I've...[Mark stands up to make his statement]

Mark Zuckerberg: You know I've already apologized in the Crimson to the ABHW, to Fuerza Latina and to any women at Harvard who may have been insulted as I take it that they were. As for any charges stemming from the breach of security, I believe I deserve some recognition from this Board.

Ad Board Chairwoman: I'm sorry?

Ad Board Chairwoman: I don't understand.

Mark Zuckerberg: Which part?

Ad Board Chairwoman: You deserve recognition?

Mark Zuckerberg: I believe I pointed out some pretty gaping holes in your system.

I had helped a friend report a security vulnerability to Facebook. It was similar in the sense that it allowed anyone who knew 2 Facebook usernames (easy to do) to post a private message to someone that would appear to come from a friend. You didn't even need to be authenticated on Facebook to do it and could do post it from any machine on the Internet.

At first Facebook was similarly dismissive that it wasn't a bug. My friend pushed a bit to convince them with additional details and examples of how it could be easily used for exploits. They finally saw the light. The bug was fixed and my friend got paid $1K which wasn't much for the bug's seriousness. In any case it got fixed and my friend got acknowledged so it's OK.

It's a bit of a pity, thought, that they didn't see it to be serious at first. I would have expected any mediocre engineer to skip a hearth beat when learning of such a bug in their system.

Figure out another way to reward this guy (maybe tell him that it's a gesture of goodwill only) and reward him. It doesn't have to be from Facebook, Inc, but he should get something from somewhere.

Otherwise, next time him or any of his friends find a vulnerability, they'd be tempted to share it with the people who would reward them, since they've seen firsthand that their reports to facebook seem to just get ignored. When you consider that his entire region is in turmoil, and that social media is clearly playing an important role in the uprisings across that region [whether you agree with them or not], you'll understand our reasons for insisting that his efforts be rewarded somehow.

Edit 1: Not suggesting that fb intentionally ignores their reports for poor English or any other reason, but that's clearly the impression they're getting.

Edit 2: And while I have no reason to believe that this guy (Khalil) would ever report a vulnerability to some dictator's security forces, others who have seen this story might. And those who have seen this need not be his friends either, since it's on HN, /r/technology, and elsewhere.

Edit 3: As tszming suggested, if you don't want to risk setting a precedent by offering cash, you could perhaps sponsor an all-expenses-paid trip (with no implications of future employment) for him to visit Facebook HQ. Granted I don't know the legal implications of this, but it does give you a chance to buy this guy lunch and tell him in person that you do appreciate his efforts, motivate him to continue reporting any vulnerabilities he finds, and tell him to encourage his friends to do the same. Actions speak louder than words, and there's no question this would have a far bigger impact than the dismissive two-liner he received, even if the intention was the same.

After watching the video, it looks like the exploit involves:

1) Getting the target user's userId. This used to be part of a user's profile URL but Facebook allowed people to choose a "vanity URL" quite a while ago, so they're no longer as visible. So, instead, the userId is obtained from a FB Graph API query.

2) The form that makes up the "post to newsfeed" has a bunch of hidden inputs. One of them refers to a "xhpc_targetid" and this is probably where the target userId is injected. It's normally set to the current user's id for a default newsfeed post. These values in the DOM are modified during the exploit using something like Chrome Developer Tools on-the-fly and the form is submitted.

If this is truly the case (and I haven't verified it myself) this means that the server side is not really checking permissions and just blindly trusting the client input. Reminded me of this recent (http://arstechnica.com/information-technology/2013/08/how-ea...) article about trusting client input.

This guy invaded the privacy of say 1-2 people that too to when the relevant authorities didn't respond in the correct manner, and saved the invasion of privacy of millions at least.

And what privacy? only a relevant post (not a spam) on profile of the company's biggest authority.

The unmentioned publication behind this method is: "A Fast Algorithm for General Raster Rotation" by Alan W. Paeth. A copy of which can be obtained here:

http://www.cipprs.org/papers/VI/VI1986/pp077-081-Paeth-1986....

While most explanations of the algorithm follow this blog post and imply that it is a three pass algorithm, if one carefully reads Paeth's paper, one realizes that the algorithm can be implemented as a one pass algorithm.

While the result isn't great, it's a neat algorithm, and it will actually do gamma correction correctly. Sampling and weighing the four pixels will not, unless you specifically code for it. And looking at the history of gamma correction in software, most developers don't care about that.

Wouldn't the 3 shears method take a preposterous amount of memory if you rotate by something like 180 degrees? The first shear will take a w.h image and output a w.h.h one!

Why not simply use Bresenham's line drawing algorithm to "draw" a reverse-rotated rectangle over your image, but rather than drawing, you'd read pixels and write them to the destination image. You'll need to only rotate the corners of the image once and everything else is simple integer math.

preposterous for the kind of device where doing it any other way is too slow

I would still rather use a simple texture mapping - map the image to a rectangle and then just rotate the 4 corner points. Rest is done naturally by your texture mapper. You can implement a texture mapper easily by finding the top-most rotated corner, take the two edge lines coming out of that corner, linearly interpolate texture coordinates on these lines for each horizontal line they cross and then simply walk linearly between those two texture positions spread across the horizontal line range. Then replace the edge line whose endpoint you reached by the next line until you reach the bottom-most corner. You can add surrounding texels to the mix to get the bilinear or another filtering. Also, Bresenham's line algorithm can be used for each of the line interpolations (though my assembly language experience showed that fixed point ints were actually faster). This is also embarrassingly parallel.

brilee 1 day ago 0 replies      
Another popular method of doing this is a variant on the area mapping technique, except that instead of taking the weighted average of the four nearest pixels, it instead creates a 2-D spline across the R/G/B "heights" of the image, and interpolate with the spline.

The reason the triple-sheared images look crappy is because the three shears themselves are subject to pixel aliasing. Still pretty cool.

Unpopular opinion of the day: bitcoin is real money, and the government will regulate it and control it as such.

In my opinion, the end-game is this: bitcoin addresses are taxable, with occasional tax agents spot-checking large accumulations of bitcoin to determine if said addresses fall within their jurisdiction. Bitcoin has the unusual ability to have a very tight trace on where a given virtual coin goes: that just makes the ability to watch the money easier.

I know very little about Bitcoin or money transmission laws. Unlike other currencies it does not seem to have fundamental dependence on any centralized arbiter, though the practicalities of large exchanges like Mt. Gox seem apparent to me. That lack of dependence on a Fed-like body appears to me like its biggest advantage, above any other potential for anonymous payment and laundering. I'd like to know what exactly is entailed in becoming compliant with money transmitting and laundering regulations and whether Bitcoin in its current form could become effectively compliant. Is that even a meaningful concept, or does the structure of Bitcoin fundamentally preclude coming into effective compliance?

"Money laundering.--The Committee understands that Bitcoins and other forms of peer-to-peer digital currency are a potential means for criminal, terrorist or other illegal organizations and individuals to illegally launder and transfer money. News reports indicate that Bitcoins may have been used to help finance the flight and activity of fugitives. The Committee directs the FBI, in consultation with the Department and other Federal partners, to provide a briefing no later 120 days after the enactment of this Act on the nature and scale of the risk posed by such ersatz currency, both in financing illegal enterprises and in undermining financial institutions. The briefing should describe the FBI efforts in the context of a coordinated Federal response to this challenge, and identify staffing and other resources devoted to this effort."

This is just the tip of the iceberg. Of course the government cares about money, and of course it wants to control the money supply. And, as a consequence, the USA will never allow any major currency inside its borders other than the US dollar.

The history of the United States is littered with the fights over who gets to determine what is money and how much of it there is: Hamilton's fight with Jefferson and Madison over the need for a central bank, Jackson during his run for the Presidency denouncing the central bank--and this becoming the main issue in the campaign, the popularity of Williams Jenning Bryan (cf. the famous "Cross of Gold" speech), etc. etc. all the way up to the horrible stagflation of the 1970s ("Whip Inflation Now!") and the recession caused by the ultimately successful efforts by Fed Chairman Paul Volcker's to end it. It is reasonable to believe--and certainly most people in the US government believe--that control of The Money is control of the economy.

Why would any successful government ever voluntarily give up that control?

As someone who does business in Linden$ et al, I (selfishly) wish the media hype around Bitcoin would simmer down, lest my own life become a lot more complicated.

> booze enables workaholism, because of the fast unwind time

I think this is the key insight from the article. I went through a stressful period where I used alcohol to wind down quickly. But in reality it just made things worse because it numbed me up to the real reasons why I was stressed out. Sometimes though, we don't want to look at the deeper issues (emotional/psychological) for why we are unhappy, and booze provides some quick and effective relief.

I've recently gotten much healthier and it's amazing to experience that the old adage about "making a lifestyle change" really is the core of it. All the different parts of your life have to hang together for the positive switch to happen. If you think of exercise and diet as a way to "pay down the debt" you'll never get out from under whatever is holding you down.

I've slipped into the habit of drinking almost every single night over the past few months and I'm currently trying to cut it out. It's harder than I thought it would be.

Like the author said, I've never noticed any physical withdrawal, but I have a strong urge to have a drink every night (sometimes even in the middle of the day). This is one of the most stressful times of my life and it's so hard not to just say "fuck it" and give up. And even when I don't really have that strong of an urge, I'm haunted by rationalizations and second guessing: "just have one," "moderate drinking isn't bad for you," etc. I'm trying to do more self tracking to prove to myself that the last one is BS.

What really sucks is I've noticed that a few beers will cause me problems with dehydration, weight gain, horrible sleep (I'm told I always freak out in the middle of the night after drinking) and yet I've developed such a tolerance that I don't even get buzzed unless I'm on an empty stomach.

As it turns out I socialize a lot in bars - and I dont like bars at all when not drinking. Mocktails help - but not enough, and basically no bars serve those in Seattle, only fancy restaurants. Which has meant more socializing at fancy restaurant bars

In general its been a mildly interesting change in behavior and a pretty good experience.

Fake beer is just bad. And I dont like sodas. And soda water seems like ostentatious abstinence.

Edit: Thanks for the suggestions! I should clearly have asked the internet before doing this, I could have been doing it much much better :)

>> ...alcoholism is often linked to highly driven, ambitious, over-achieving personality types...

I have come across this point multiple times in the past -- reading or conversing -- but never has a concrete source or study been cited. Not to say I don't agree with it -- anecdotal evidence is not always false.

It is really true though? I consider myself very driven and ambitious and also have a drinking habit, but know a few others who don't.

Went from drinking way too much (Think black out) to zero recently. It was actually surprisingly easy - weirdly effortless.

What freaks me out though is how difficult it is to hit the sweet spot. i.e. To drink, but low-moderate amounts and only irregularly. That would be ideal in my view - I don't seem to have sufficient willpower for that yet, so its zero drinks for now.

I know a lot of people who are similarly dependent upon (if not outright addicted to) exercise. Typically running although I've seen it with cycling and swimming as well. For these people if they don't get their exercise on schedule, they go absolutely nuts. There are many benefits to exercise but for many there are also big big risks, e.g. joint problems, soft tissue injuries, etc.

I was a heavy drinker, at some points a 6 pack a night, for well over 10 years and I quit cold turkey and have been sober for going on 5 years now. There was definitely a point where getting to bed was a task but I'm such a changed person emotionally and mentally than I was when drinking. Somethings are just not for everyone. The worst part was definitely seeing who my real friends were and who were just the people who I drank with.

I quit drinking six years ago cold turkey. Working for myself it was always easy to find a time/reason to have a drink and I realized it wasn't heading down a good path. My wife and I were also looking to have kids and I decided I didn't want to drink around them. For awhile people either didn't understand it or were amazed that I just quit (I love to party, still do!).

My best friend kept nagging me about having a few beers with him when I visited. Since we both smoked for a short time in high school I suggested that we, instead, buy a pack of cigarettes and smoke a few while we're hanging out. "But I don't smoke anymore." Lightbulb moment.

The biggest thing i realized is that drinking is something to do. You hang out with the same people at the same bars talking about the same crap. Initially it's pretty boring when you quit but I really don't even think about it anymore. I will say that in the time since I quit drinking I had two kids, my business has seen year over year success and I've completed an Ironman triathlon.

Tips on abstaining:

* Don't keep any alcohol in your house

* Don't go anywhere that drinking is the primary focus, or even secondary focus

* Pick up a regular hobby that makes you happy and do it at least three times a week

* Talk to people you enjoy and join them in activities that don't involve drinking

* Put the amount of money you'd normally have spent on booze into a piggy bank and watch it grow

* Make a list of things that make you happy, and revisit it when you're feeling down (instead of revisiting booze)

* Get a buddy to abstain with you from drinking or smoking for mutual moral support

* Put an 'X' on a calendar for every day you don't drink

* If you find it difficult, give yourself an arbitrary goal date. Once you reach it, try to extend it further

* Make it easier for you to drink healthy things by getting things you need (tea infusers, pitchers, juice concentrate, water bottles, etc)

(I recently did two months, which was much harder for me than I anticipated, but I finally got over the hump and have had very little to drink for weeks. Feels nice to have more productive things to do than burn money and feel run down in the morning, and i'm looking better too!)

I have learned distrust. I distrust anything that makes me feel good without having achieved something that merits that sensation.

Alcohol is like being wrapped in a comforter. You are warm, the world is soft, and like a child, you trust in everything turning out alright.

This has no relationship to the real world.

While I have enjoyed alcohol many times, and both drunk to excess and been a social drinker, I find that it distracts me. It distracts from what I should be paying attention to, while I'm busy feeling good and safe.

>I did find it more difficult to remain polite in the presence of people who were actively annoying me, but I managed to hold my tongue in most cases.

Recently, I did a 42-day voluntary abstention from drinking. And, unlike everyone else I know who has tried this, I didn't cheat. It was inspired by a 21-day abstention a few months prior, which was due to a backpacking trip on which we decided not to bring any booze.

At the end of these periods I felt great, physically and mentally. After starting up again, my alcohol consumption was less than it used to be. Sleep was better than ever, and I wake up feeling refreshed - the better sleep is far and above the most noticeable effect. Generally I just feel healthier.

The social thing is a challenge, but not impossible. I actually forced myself not to go out any less, I still kept every plan with friends to visit bars, clubs, etc. Just drank a club soda. I quoted the above because I had a similar experience: when you are sober, you quickly realize that there are a few or several of your friends who you cannot stand to be around sober. You realize how annoying they are.

It was fun pushing myself for three and then six weeks. It inspired me to follow up with a three-day water fast (that was particularly painful, again I did not cheat). I am interested if any HN readers have suggestions of other self-denial tasks to try out.

I personally enjoy a tasty beverage on occasion. But if I were to go 40 days without drinking I'm not sure that I would even notice. The OP doesn't sound like he was a particularly heavy drinker, but it always has a slight problematic ring to me when somebody tells me they haven't drank for X number of days. Especially when X is a fairly small number. I always figure that since they're tracking the time so specifically that they must be dying for a drink.

I stopped for a few months several years ago (to study for the GMAT, of all things). Granted, this coincided with me actively practicing puzzles and trick questions (essentially this is what the high end questions are) but I felt noticeably sharper. Like I'd gained 10-20 IQ points. Prior to this I drank quite often over several years (college plus a few post college years). This break (and my awareness of its effects) caused me to really curb my drinking. Now I drink sparsely and mostly to appreciate a nice wine or beer or well made cocktail. I think there's a balance to strike. Enjoyment in life might be worth a marginal IQ point here and there. I dropped out of bschool but learned this lesson getting myself admitted. Thanks bschool! :D

I rarely drink maybe one beer a month at my wildest but I live in a province of sport drinkers where weekdays but especially the weekend people drink until the pass out. Most events are attended by people who drank before arriving which is common but I mean they started drinking at 7am and the event is at 10pm.

Currently I a non-drinker have non-alcoholic fatty liver disease which sucks because it's insulting for me to have of all things what is considered a disease of heavy drinkers. It hurts, I mean my liver actually hurts and it's frightening to have a problem like this a damaged organ in my body. I'm not even fat my friends all ask how I keep so thin, I mean I'm 5'8" short for a guy and at my peak I was 180 pounds but you'd never know it by looking at me, but all my life up to a few years ago I was a consistent 150 pounds. I'm down to 165 pounds but still my doctor telling my my risk of heart attack and stroke is double due to a fatty liver, and this from a family of people who all die from a stroke or heart attack.

Your liver is precious! I don't think people realize how important it is they hear jokes about their liver when drinking to the point it's a joke or just noise more than advice. Then Tylenol the next day to fix their hangover which damages the liver even more.

You liver is the only organ which can regenerate but I would guess not from systemic damage only physical damage to specific defined areas.

Long live our livers!

A summary for those not following along at home:

The Youtube app for Android is developed by Google

The Youtube app for iOS is developed by Google

The Youtube app for Windows Phone is developed by Microsoft, with some reverse engineering, at first not serving ads on purpose.

It is easy to argue that a Youtube app for Windows Phone would be nice for WP users. It is also easy to argue that MSFT writing such an app would be a tad antagonistic, seeing as the first version released contained no ads. One might suspect Microsoft wanted a PR fight more than they wanted a Youtube app, or that they wanted both.

Alas, we can read for clues.

The title of the article is: "The limits of Googles openness"

But the tags are: "marketplace, Windows Phone"

It's not an article about Google now, is it?

~~~

The article doesn't help WP users. Instead they get no Youtube app while watching a hissy fit occur if they google (ha) to find out why the app is gone.

I like both these companies, but for however-much of a PR stunt this is, Microsoft does not come out looking good.

Disclosure: I am a Googler, though not working on anything remotely near YouTube. Obvious caveat: this is just my personal opinion.

> With this backdrop, we temporarily took down our full-featured app when Google objected to it last May

If I remember right, this full-featured app included features like:

1. Allowing users to download videos even when the content provider disallowed that.

2. Allowing users to not view ads even when the content provider specifically required ads to be shown.

3. Using YouTube's branding without permission.

I am but a lowly engineer and the actions of executives confuse me, but I don't see how Microsoft didn't realize the above was batshit crazy. I can only assume this is some sort of weird ploy.

YouTube's entire business model is about getting content providers to put videos up there so that people will watch ads to see them. If you let people take videos off the site, or just skip the ads, that breaks the fundamental business proposition.

This would be like me making an Android app called "Bing from Micrsoft" that let you perform bing searches but then stripped out all of the ads. Microsoft would shut that shit down, with good reason.

> When we first built a YouTube app for Windows Phone, we did so with the understanding that Google claimed to grow its business based on open access to its platforms and content, a point it reiterated last year.

"Open access to content" doesn't mean "ignore the requirements of the people who created that content". People make their livelihoods producing YouTube videos and the only way that money flows to those creators is because of ads. If you make a Windows Phone app that lets you watch Cooking with Dog without the ads, you aren't doing Francis any favors by giving out "open access" to his content.

(Yes, I did just imply that they are the dog's videos. He is the host, after all.)

It's my understanding that YouTube officially supports access via either a Flash applet or the HTML5 <video> tag. Windows Phone doesn't support Flash[1], so the only option for writing a mobile app using the official API is to use HTML5.

It's not obvious why using the HTML5 API is "impossible". Windows bundles a <video>-capable browser; assuming IE's capable of playing either H.264 or WebM, it should be relatively easy to build a YouTube app on top of it. Maybe there's some internal reason why an app can't easily embed an IE widget.

Some background for people who may not have followed this:

In May, Microsoft released a YouTube app for Windows Phone that didn't show ads and allowed users to download videos. Google said no.

Microsoft removed the download capability but didn't restore the ads. Google said no.

Then the PR comes out that Microsoft and Google are working together on a new app. I'm guessing that was PR from Microsoft's side.

Now Microsoft has tried to release an app that follows the rules but Google looks like they are being petty about it after Microsoft has repeatedly violated their terms of service.

So Microsoft posts a blog article angling for FTC intervention, and here we are.

Really annoying Google blocks IMs from other services now as well. Lots of people complain to me they can't IM Google users any more. Apparently Google removed server to server XMPP support, a standard open IM protocol, in favor of their own lock in protocols. Other products are following suit, Chromecast doesn't include support DLNA or other standards for example, but tries to force you to use Google proprietary stuff instead. In many cases this is a worse situation for users and only benefits Google by locking more people in and forcing more people to use services that aren't superior. Many people have their own media center or media server setups that are incompatible for example, like XBMC, a popular media center.

I'd be more inclined to give Google a bit of leeway here if they hadn't already pulled out some petty behaviour against Windows Phone.

This is somewhat similar to Google's blocking of Maps from the Windows Phone web browser. A feature that worked fine originally and once there was uproar from users came back and continued to work fine.

Google is attempting to deny service to Windows Phone users to avoid competition in the handheld market. It isn't pretty and it does make me rethink my daily usage of Google services. Windows Phone users are Google customers too and I couldn't care less about their petty rivalry with some other mega-corp.

This discussion brings up the point about how the usage requirements and restrictions of the API applies to third-parties and not Google itself. If Google, for example, wanted to keep the iOS platforms and Android platforms in an advantageous spot for whatever reason, they could just write the apps for those platforms themselves and say that the terms don't apply.

I'm not saying that's what happened in this case. It sounds like Microsoft's application added features that even Google wouldn't give its own apps. However, the argument that Google is simply allowed to write its own apps, for its own platforms and them impose extra restrictions on third parties who use its APIs is anti-competitive. This is the kinda crap that got Microsoft in trouble in the first place.

Again, I'm only speaking to the argument I see in the threads here, not the reality as it appears in the story. In reality, it appears Microsoft may have overstepped a bit.

M$: "Google also says that we are not complying with its 'terms and conditions.' What Google really means is that our app is not based on HTML5. The problem with this argument, of course, is that Google is not complying with this condition for Android and iPhone."

Google's T&Cs that M$ is citing, it would seem to me, apply to third-party use of YouTube data. Since Google wrote the Android and iOS YouTube apps, this is not "third-party use." Google makes the rules for YouTube, and can therefore bypass them with impunity. M$ cannot.

Presumably, a Google-written YouTube app for WinPhone would also be allowed to be non-HTML5. However, I'm sure readers here have a pretty good grasp on the chances of that happening.

It seems Google will allow them to build an HTML5 app, even though Microsoft has repeatedly breached their TOS multiple times (like allowing users to download the videos). If Microsoft's WP8 platform is so behind the times, it can't even make an HTML5 web-app possible, that's really Microsoft's problem.

If I'm not mistaken all the other "native" Youtube apps on other platforms are Google's own apps, and it's also their prerogative to choose the platforms they want to make native apps on. For example, they haven't made one for Roku either, and it's the #1 media streaming box right now.

So I don't see the problem here?

EDIT: One other thing. Google told them from the beginning that they'll only allow an HTML5 app. So what does Microsoft do? They make a native app - again. And then Microsoft releases the native app to their store, without Google's approval, even though they were supposedly "collaborating" on this, and then seeds press releases to the media that Google-the-bad-guy blocked them "again" - like it was "completely unexpected" or something.

Pretty good work. My thoughts on the visualization:

Criticisms:1) The moving around over the city skyline is slick and fun, but I doubt it conveys much useful information. I'd rather see the growth of new building over time. In visualization, motion should convey some meaning. Here it doesn't seem to.2) It's important for visualizations to convey both anecdotal information (achieved through the before/after snapshots). But it's also important to convey quantitative information, magnitude and directions of changes. I don't detect anything like that here, even though there is quantitative information embedded in the text (e.g. "Population is up 2,000, but 600 poor people have left"). Numbers are good, visualizations that artfully convey the magnitude and direction of relevant numbers are even better. It's rare to have news narrative that can't be improved by conveying the quantities involved.

Things they did right:1) The before/after snapshots are useful and pack a punch.2) Inclusive. The visualization includes a a variety of changes and doesn't get sucked down a narrowly focused rabbit hole.3) Simplicity. It's not a data dump. The visualization does a decent job of conveying single themes without including unnecessary extra. It may go too far with this though (see criticism #2 above).

Overall, I look forward to more visualizations like this from NYT and other media outlets.

Woud be interesting to see the backstory on how they got access to the data/subsamples. The visuals are well done, but the story is sort of interesting in terms of how its edited. It neglects any mention, for example, of the role of Finance in the building boom. And by extension, glosses over the Financial crisis spawned (under his tenure, in new york) by real-estate investment instruments and the general bubble-icous tendencies that follow from "free money". NYC basically skims the profits of wall street both directly (retail&real estate sails subsidized by incomes from the financial sector) and indirectly through double taxation of corporation (financial lagest sector) and city income taxes. So, there are a lot of grandmother's withs withered pensions and decimated savings outside of New York that are basically subsidizing all of this. Just worth thinking about.

I've yet to devote any significant amount of time to developing on Node but this is a big +1 for more serious consideration.

My memory is fuzzy (this was well over a year ago) but I remember building an app in express and it being completely broken by updates a very short time later (along with a good number of other modules that hadn't been updated either).

Anyone venture out a guess/opinion on how many things in userland will stabilize because of this? (Or perhaps things already have- I don't hear as many complaints about express' api changing lately).

As developer time will stay the biggest expense when developing software, I am bullish on Node and JavaScript.

This is really cool.

It's completely backwards from my personal usage of the Internet; I get away with browsing online using a Penryn-era Pentium, a ARM-based Chromebook, and/or my Galaxy Nexus precisely because the majority of processing costs are offloaded on "traditional" websites rather than on the browser doing the rendering.

But if this means that application developers won't have to recompile every application under the sun (like, say, ffmpeg or Audacity) to run under asm.js or PNaCl, then I think it could mean that we could skip a decade or two of having to reinvent the wheel.

On the other hand, this feels suspiciously reminiscent of ActiveX, so I suspect you're going to have a hard time convincing people to adopt it if the security diehards warn you of running arbitrary code on your machine (even if it is in a sandbox).

Security wise, this seems like an awful idea: Unless the host is firewalled from the guest, if Arc-style VMs become popular, than you'll have malicious websites starting VMs to scan your host network for unpatched vulnerabilities, and abuse them.

I try to keep my network secure, but e.g. Cisco/Linksys E3000 hasn't received a firmware update in a long time, and it has known exploitable bugs - right now, the fact that it is only accessible from inside the NAT, and that webpages can't do arbitrary accesses is what keeps all those E3000s from being exploited.

(My E3000 has been running dd-wrt, so it's not vulnerable to those problems; but I had to manually upgrade the dropbear ssh because of vulnerabilities - latest official dd-wrt for it is still vulnerable)

Desktop client disk space is large enough to have a VM for many sites. In the future, if it increases enough to have a VM for every web application _and_ work offline you have the selling point that the app can work during infrastructure failures. People will buy that. Sandbox the networking so it only can call your site and you have solved some of the security problems mentioned. Trouble is, large amount $$$ is behind tablets and their ilk. So you have to work on this for another 10 years when desktops come back. That will happen when Moore's law returns into existence. Light-based computing or analog-fusion-digital computing comes on the scene. What you have is a homomorphism to just a desktop application. The browser has grown to be a glorified dumb terminal that can display rich interfaces, and so the lines are blurred enough to confuse anyone trying to handle the client/server distinction. Best bet is to turn it into a platform that enterprises can use to solve their existing problems. Niche play. Great work, BTW.

This is a terrible idea. The author needs to stop what they're doing right now, from a security context this is really quite dangerous.

Arc uses a desktop virtualisation tool to run arbitrary code on your system. The manifest provides a set of packages to download and install and a series of commands to execute inside the downloaded Arc VM image. A malicious server could use this to run an app that attacks your network, the host, acts as a bot, anything.

I'm assuming that in order to run native code like this, there's no sandboxing. I've seen no mention of it. There's a reason you can't run native code in the browser without restrictions, and this bypasses all of that.

I've thought about how to do this securely (using hardware) -- an awesome end state would be letting a data owner with local data, and a code author in the cloud, both mutually distrustful, allow data owner's data to be processed by code owner in a safe way mutually agreed by each. You could do this with trustworthy computing, or a dedicated trusted third party environment on the net, or maybe with MPC someday.

Not sure if Linux or x86 vm is the right level of abstraction; maybe the "peggo" level where you have a higher level might be better for users. Maybe even something like Docker (but on the client)?

And what happens to the VM when the user closes their arc app? It seems like you could build really powerful tools that leverage saving the state of the VM between sessions.Suppose I build an arc text editor/image manipulator, something where my workflow is boot program --> load file X --> edit file X --> save file X. In theory I could save states of the entire app between sessions, so the whole workflow becomes boot arc app --> edit file... And I could do this for any app I build in arc... Am I getting this right? Because that would be absolutely incredible for building session persistence without a home-brew backend.

cool, looks like the natural extension of client-side programming.why should we be limited to running things in the browser while our local machines remain underutilized? just spin up a sandboxed VM via Arc - brilliant! and - like so often - a seemingly obvious idea in hindsight...

should also be great for downloading torrents in a sandboxed environment.

The name Dread Pirate Roberts should've given away the fact the site is supposed to be handed down to different operators if you read/watched Princess Bride.

This guy is making a fatal mistake of talking to the press. History shows all blackmarket admins like Max Vision go down shortly after press articles come out with interviews. Now he went from guy running a drug site to "subverting the US with propaganda" so the NSA can get involved. Note to future outlaws: resist the temptation to make yourself famous by giving interviews. Just look how they amped the Swartz case after he went to the media

Can also now make a pretty good profile of this guy because he talks too much on his own forum and to forbes.

You'd stand to make at least millions if you did it right.

The name "Dread Pirate Roberts" is (quite cleverly, IMHO) picked up from the character from The Princess Bride [aside: go watch the film -- it's great fun!].

It is possible that this "person" is much like Satoshi Nakamoto, given that in The Princess Bride, the pirate is not actually one person, but a series of individuals who periodically pass the name and reputation to a chosen successor.

If you are struggling to pin an ideology on an enterprise like the Silk Road, consider ways in which our current rate of technological/scientific progress has been shaped and guided by the responsible use of psychedelics in the 20th century. Check out the relationships that Francis Crick, Kary Mullis, Steve Jobs and Kiyoshi Izumi had with these fascinating compounds to start. From there it is not difficult for one to rationally assert that Silk Road (and Roberts) are critical facilitators - spurring innovation by furnishing those that might conceptualize the future with a powerful means to do so.

I guess 1.2M/month -> (30M - 45M)/yr makes the growth like much higher than :

1.2M/month -> (2.5 - 3.75M)/month14.4M/yr -> (30M - 45M)/yr

Maybe he should have written revenue increasing is from 1.2M/month to 45,000,0000 per year.

First of all: ber-cool.

Minor bug, Beethoven's 5th was off by a measure for me. (Goldberg variation was spot-on).

Also, right/left arrow keys aren't skipping measures (as the keyboard page says), but are skipping whole sets of measures.

But overall, as a musician, I actually found it rather distracting to watch the line try to follow the notes exactly, as the line constantly sped up and slowed down due to rubato, etc. -- indeed, in particularly fluid pieces, it can even be possible that the right and left hands don't match up precisely in actual performance.

It might actually be more clear, and far less distracting, if you followed the time signature for the beat, and simply highlighted all notes in the current beat within a light-pink rectangle overlay, and then that box would instantly disappear, and the next one appear, upon the next beat.

That way, we can focus with our ears on the actual movement in the music, without being distracted by visual movement, but still have a perfect visual indicator of where we are.

But anyways, great work and great idea! Kudos, well-done!

roryokane 1 day ago 2 replies      
I like this. Im not as impressed with it as many others seem to be, since Ive worked with Encore and Sibelius a lot and they have almost this exact feature. That is, they play synthesized audio while moving the bar along with the sheet music. But it is nice to have better-played music to listen to while following along with sheet music.

I do also sometimes pull up some classical sheet music and try to read it along with a recording. So if you get a bigger library that includes pieces I end up being interested in, your site would be useful in that respect. I would enjoy the safety of having the red bar following along to make sure I dont lose my place.

You said on https://news.ycombinator.com/item?id=6226990 that the left and right arrow keys should move by page, and not by measure, and theyre just mislabeled. I think it would actually be more helpful for the arrow keys to move by measure. Thats what Im used to in other programs, and I would want to do that more often. I often move back a measure or three back to replay a complicated part I just heard. Moving back a whole page is too much, and using the mouse to click the previous measure is less efficient. You could still keep the keyboard page-moving functions, but bind them to Page Up and Page Down instead.

Ive used Transcribe! (http://www.seventhstring.com/xscribe/overview.html) before to manually mark up the measures and beats of pieces. You say you have some JavaScript tool that helps you mark up pieces, and I would love to see it, but you might also want to look at Transcribe! and see if that makes marking up pieces easier. Transcribe! uses a proprietary file format, but its not too hard to extract the beat times by parsing the text of the file.

Another scrolling method you could try to help people keep their place is showing two rows/systems at once. When you get to the end (right side) of one row, move the bar to the left side of the next row, and then scroll the next row up, displaying the row after that below it. Im thinking of the effect in this video, which uses Finale Notepad: http://www.youtube.com/watch?v=CxTav4S-4Tk.

Listening to classical pieces with the score was one of my favourite things to do when I was at music school.

Good for context as you're following along.

Super nice work though.

I like it. I have a few suggestions (full disclosure: I haven't played music since high school).

It would be nice if the key and time signature could remain onscreen as the sheet scrolls.

I think my preferred solution for scrolling would be to have the position marker move until it hits the center, then have the position stay centered while the sheet scrolls until it hits the end. I'm not sure what the correct way to handle repeats in my scenario would be--perhaps have the sheet stop scrolling when it hits a repeat.

A few minor things: While jumping to time points works, scrubbing does not. Instead, the notes image gets dragged. You could embed the image as a background-image instead of an <img> to prevent that. Or catch the dragstart event on it and return false (http://stackoverflow.com/questions/4211909/disable-dragging-...). A custom Rails error page or better error handling would also be nice (http://notezilla.io/bla). And there are a few console.log's left (TIME!!!! :)
