In the last chapter, Bonus Projects, the author mentions Static Typing & type systems. If anyone's interested in learning more:

I've implemented a few simple implementations of basic (and not so basic) type systems[1]. Currently, only 3 type systems are finished (Hindley Milner's Algorithm W, and Daan Leijen's extensible rows and first-class polymorphism), while gradual typing is almost done (based on [2], in branch 'dev').

This is a good stuff. 4 years ago, I wrote a Lisp in 500 lines of C in one day after finishing SICP. Typing it out did made what I learned more concrete.

I always find it so hard to help out proof-reading code for causes like this.

Often, the code is more complicated than I find reasonable, while omitting things that make a lot of sense in "real" code, and it's very hard to know as an outside reader what the exact motivation for each decision was, by the author.

A few such things that caused me to WTF:

The initial few examples use a pointlessly static and global line buffer, instead of declaring the line buffer where it's being used.

There is hardly any const in the code, even for cases where it obviously should (to me) be used, i.e. for variables that are never written once given their initial value.

A magic number (the buffer size 2048) is repeated in the code, and even encoded into a comment, instead of just using "sizeof buffer".

I do think I found an actual bug (on http://www.buildyourownlisp.com/chapter4_interactive_prompt)... the readline() implementation ignores its prompt argument and uses a hardcoded string, instead. The same function also does strcpy() followed by using strlen() to truncate the string it just copied; that really doesn't sit well with me.

Sounds like this may subvert Greenspun's Tenth Rule:

"Any sufficiently complicated C or Fortran program contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of Common Lisp."

I dislike the use of a parser generator libary. If it were any other language, sure. But Lisp is so easy to parse. Writing parsers is fun, and it would be a good exercise. I applaud you for wanting to teach beginners how to install libraries, but this seems like the wrong choice.

Props for mentioning conditional compilation early. It's underrepresented in books but essential for real life.

Thank you for writing this and sharing it for the common good. I've been wanting to relearn C since I've switched to Python for work. Hopefully this book will be good practice because I've been wanting to implement a Lisp interpreter on a micro controller for quite sometime. I have plenty of PIC18F4550 micro controllers lying around.

Also, I liked the cat pictures and hope you'll add more of those in the next edition, perhaps.

If the author is reading this, thank you very much - I've always wanted to experiment with C, but never had a project to use it on. Writing a Lisp interpreter (compiler?) is not one that occurred to me, but it definitely interests me.

Cheers for your hard work. :)

Fine to implement something. But I would wish that the language implemented actually looks like Lisp or Scheme.

Currently this claims to be Lisp, but it is some strange version of it.

Using a Scheme or Lisp has a lot of advantages:

* one can compare it with other actually working implementations

* there is already a wealth of material to learn from or where code could be reused

* many books exist

* the language actually has already got some thought

A good example is the book on Scheme 9:

If you are interested in this, you may find one of my Lisp implementation interesting too. It's implemented less than 1k lines of heavily-commented C, but it even supports a macro system and copying GC in addition to the common features you would usually see in small Lisps.

akkartik 2 days ago 0 replies      
In similar vein to tomp's comment: if someone's interested in the bonus project of implementing macros, I've implemented a simple lisp with first class macros (fexprs): http://github.com/akkartik/wart. Moreover, you can write anonymous macros out of more primitive constructs.

Over time it's accumulated other features: http://akkartik.name/post/wart. But hopefully it's still easy to understand, because it has thorough unit tests. If you have a question about some line of code you can try changing it. Seeing what tests break is a great way to get feedback as you learn, in my experience.

On the compiler course taught by Brucee (Bruce Ellis - one half of Mark V. Shaney - the other half being Rob Pike) he got you to do two projects : write a Lisp implementation in C, and a C compiler in Lisp. Most instructive.

At my undergrad institution, we have a class that does a project very similar to this. I recently completed the class and project and have a bit of advice for anyone looking to take up this challenge on their own.

First off, a small note: our project used C to implement Scheme (a lisp dialect), so it's similar but not exactly the same as this.

I'd recommend starting off with reading about the principles and coming up with a solution to each of the problems on your own instead of following a specific pattern as outlined in the book. For example, in our project, we decided to learn about the C basics, then just figure out how to make it 'act' like Scheme if given an input. Eventually, we thought of doing everything in a linked-list style to make organization and recursion easier and more natural, but coming to this conclusion on our own was very helpful.

Another thing is valgrind. As far as I could find, the text only mentions valgrind in one paragraph, but it's an excellent tool to check for memory leaks and errors.

Also, as mentioned in the book, a bonus is adding in GC. This turns out to be a pretty easy and a fun exploration of the different techniques available if you try a couple out for performance.

Our code in case you're interested: https://bitbucket.org/adamcanady/cs251_interpreter/src

Thanks for writing this. I find your writing style to be very easy to follow. I've wanted to play with a toy language for some time, so I'm very excited to dive into your book with both feet. I'm working on Windows and am up to chapter 6. Very enjoyable. The only suggestions I would offer is perhaps to mention that AST stands for Abstract Syntax Tree. It seems this book is targeted to less experienced programmers, so it may be helpful to mention what AST means in this context. Thank you for your hard work and willingness to share your knowledge.

I was trying to implement an interpreter for a minimal (lazy) language in C [1]. It uses Church encoding and other encodings. E.g. here are the definitions of false, true, identity, and pair:

    f_ = proc_self(lambda(v0));    t_ = proc(lambda(v1), f());    id_ = proc(v0, f());    pair_ = lambda3(op_if(v0, v1, v2));
For the moment I gave up on it though but maybe it might serve as inspiration ;)

HN'ers asking why this isn't a cell phone app take note - this exemplifies why we (geeks) don't make good use cases for consumer tech and we should always be careful looking to our own habits and values when in a Product Development role.

We're rarely the target customer and rarely behave like "average Joe". We're naturally resistant to superfluous redundancy ("My phone can already snap a barcode, I don't need a separate device") when consumers don't even see the duplication let alone the issue. They don't separate devices (or even apps) has having layers of similarity and just see things for their end functionality.

My mother would see a phone and apps as completely separate functionality to a physical device like this. She probably would have the Amazon Fresh scanner, the (theoretical) Google Shopping Express scanner and the (also theoretical) Whole Foods scanner and wouldn't even consider the duplication, let alone be frustrated by it. She doesn't care about the potential for an "open standard"/"common standard".

She also has an AppleTV and a ChromeCast connected to the same smart-TV that also has native apps within it (she mostly uses the native apps). Again, she sees no issue with that and might even buy an Amazon FireTV if she felt it was more compelling for one use.

Ultimately we shouldn't assume consumers value convergence, especially when it creates ever increasing complexity in user experience (eg opening an app to snap a barcode vs pressing a single button on an Amazon Fresh scanner)

ADDED: If you don't have parents that also work in tech, go visit them and just watch them use technology without prompting. Ask them about their experiences, their frustrations, their decisions behind purchasing specific equipment and downloading particular apps. It's very insightful.

Based on the comments, I'm guessing few poeople here have ever worked retail and held a barcode scanner.

Break out your phone, load up your barcode scanning app (there's 20 seconds right there even if the phone is in your pocket). Now try to actually scan something with it. You'll spend another 30 seconds lining up the little on-screen window with the code, rotating things, waiting for the camera to focus, and even having to move to another location if you're not in bright lighting. It's a terrible experience and that's why you don't see stores checking people out using the camera of an iPad.

A barcode scanner, on the other hand, just works. You point it in the general vicinity of the barcode, press the button, and it's scanned. You don't have to perfectly align anything, be in specific lighting, or wait for a camera and an app. I'm sure you've seen cashiers run multiple things over a scanner in under a second.

Amazon Dash isn't just a subset of your phone's functionality. It's a dedicated barcode scanner, which is hardware you don't have on your phone.

My first thought: people are going to bring this to retail shops to get the benefits of brick-and-mortars shopping while benefiting from the low prices / delivery of Amazon.

A lot of people already kind of do this. They go to a shop, find the items they like and look up on the web if they can get a cheaper price by ordering online.

This version of the product might not be so practical for this use case though since it requires a WiFi connection and can probably only scan AmazonFresh barcodes.

Number of steps to scan grocery by phone:

1. Find your phone

2. Unlock

3. Swipe left to home page three or maybe four

4. Visually scan for the AmazonFresh icon and tap

5. Wait for loading

6. Start scanning action

7. Confirm and pay

Number of steps to scan grocery by Dash:

1. Get device from drawer or pantry

2. Press one button and scan

3. Confirm and pay

For the target demo (30+, married, households with children), option 2 wins hands down. Because you will easily be distracted and stop using option 1 and not complete checkout.

Amazon knows CPG and commerce better than you do.

Amazon needs to scale Fresh in order for it to be more successful. On a micro level, scaling could come in one of 2 ways: (1)increase order frequency or (2)average order size.

(1) Order frequency - Right now, a typical customer likely picks up groceries when they're out and it's convenient. This very well could be on the commute home from work, later at night, etc. With Dash sitting around the kitchen, Amazon has now created a very tangible reminder in the form of the Dash device to order your groceries, rather than waiting until it pops into your mind (and possibly not buying on Amazon).

(2) Average order size - As someone posted above, it takes 1 or 2 button clicks to reorder an item using Dash. Compared to the current way of online grocery shopping, Dash eliminates a lot of possibilities of forgetting to reorder something you intended to, because it is so simple. Compared to on the PC when you may forget to browse the snacks category, for example, and you forget to order chips and cookies. Way less likely to happen with Dash.

This doesn't address price concerns, but in terms of convenience for Amazon Fresh customers & increasing Fresh orders/order size, this seems like a massive win-win for Amazon and their customers.

I'm surprised this exists to be honest. Not because of smartphones, but because I thought RFID chips would be sufficiently disposable by now that we'd have smart refrigerators and trashcans. I had to buy a new refrigerator last year and I was struck by how many different kinds of ice dispensers there were (a feature in which I have no interest whatsoever) vs smart refrigerators. I found exactly one of the latter - the unfortunately named T9000 from Samsung (Komm vith me if you vant a snack...), which is really just a refrigerator with a tablet stuck on the front, didn't do very much, was completely locked down (understandable) and cost $4000.

I like how it's a separate device - it's too bad it's only available on the west coast though. AmazonFresh reminds me of "Webvan". Webvan failed during the dot com bubble, maybe Amazon is trying to start this kind of business model up again. I think the grocery delivery service is a great idea, especially now with everyone being so connected. Webvan only failed because they expanded rapidy and weren't able to attract customers at their speedy pace, plus back then not everyone was so connected.

Knowing this distraction, if I just say - "OK, I will just remember in my brain and will not pick up phone" then you know I never remember that task or things later.

Like others have said, it really depends on what you're selling and who you're targetting.

Our example (country specific mobile app for doctors), spent 100 on AdWords, end result was literally 0 app installs, 0 sign-ups, 0 everything. Medical keywords are expensive, no chance of sending them directly to the App Store/Play Store (that we saw at least), and no other useful targetting.

Here come Facebook mobile install ads. 40 spent so far, 500+ app installs, 200+ sign-ups, great retention. We can roughly target medical professionals, take them directly to the app stores, and the clicks are cheap as hell.

I have no doubt that AdWords work much better in other cases, and that FB can be useless, but it's not black and white, you need to know which tool fits the purpose.

Within the last week I performed a similar "experiment" for newly created facebook.com/AmeriStartup.

I created two FB mobile advertisements to direct traffic to the website, though the website is more eCommerce/service than any type of sign up. Budget $50 over 3 days reach was ~20,000+; the click through rate was .5% and .4% for the 2 ads; just under 100 clicks to the website with none resulting in conversion.

More disturbing was the fan page promotion through FB (paid "Likes" in my own words). $10 budget per day over 3 days; reach = 3,000+; total likes 34. What disturbed me though was when I would go to the profile page of the users who "liked" the fan page as a result of the promotion, many of the user profiles did not appear to be legit. Moreover, the majority of these users who liked the page had a single facebook post in their entire facebook timeline. As unlikely as it is that of ~30 paid likes nearly all were were inactive facebook users who were otherwise compelled to interact with my paid promotion, it is equally unlikely that facebook would be so brazen in committing fraud on advertisers by creating and managing fake accounts to click paid promotion/ads which could easily be proven. Nevertheless is begs the question what are these accounts (fake, bots, ect...) and who controls them and why?

This is a single campaign, and a single test, with one set of variables. Concluding something overreaching like "Facebook CPC ads don't work" after a test like that is like saying, "I tried mixing two chemicals, and there was no reaction, chemicals must not cause reactions."

Think of it like a computer program. If 99% of the program is right but one thing is broken, the entire thing won't work. Marketing is, in a lot of respects, the same way. You can be missing one single variable and your entire campaign falls apart.

Look at all of the variables in this campaign - title, image, targeting options, whether you do sidebar ads, newsfeed ads, or mobile newsfeed, and most importantly the product/service offered on the other side (not to mention the conversion rate of the specific landing pages). Apparently this campaign wasn't profitable, but I run a half dozen profitable campaigns on Facebook at any given time (most of them CPC), and I know people who spend $10,000/day on Facebook ads.

Facebook ads do work under the right circumstances. Concluding that they don't after one try is a little absurd.

I don't know about the bot/fraud accusation, but do not listen to the conclusion here. Those bounce rates are not the overall average and it's irrelevant anyway. With any online advertising you need to track conversions. Optimize & spend based on those, not based on hearsay or anecdotes. Hearsay and anecdotes are for deciding to try it and Facebook is so big that you should try it anyway.

There are unlimited examples of failed advertising campaigns on every single medium where failure can be seen measured. Most campaigns fail. They are a cost of doing business. Generalizing based on those would be very mistaken. Facebook is a new but giant ad program. The tools are still rough and "best practices" are even rougher. The consultants...

That doesn't mean that good campaigns can't be run on facebook. Facebook allows campaigns to be run that would be impossible to run anywhere else. In some cases the ROI is ridiculous. In others it's one of few things that works.

The number one reason for all these Facebook sux rants seems to be "it's not adwords." People want their adwords campaign to work on Facebook. If Coca Cola wanted to tell you that they're "the real thing" on adwords, it would be an uphill battle. A budget app on Facebook might be hard going on fb. Maybe not impossible, but it's a squeeze.

If you want to advertise a local children's art exhibition taking place this weekend, Facebook ads will work like magic. 'Friends of friends of the gallery who live close by and have kids.' There is no other platform that gives you anywhere near the reach, relevance and context that FB gives you for a campaign like that. I would expect the "ROI" to be under a dollar per physical ass-through-door.

I made this comment the other day in a thread about children accidentally clicking on google display ads, but I think it also applies here. The problem is measuring the effectiveness of early funnel ads from clicks.

Here is a good presentation from the quantcast guys about the "natural born clicker" problem. The people clicking on your display ad are probably anything but actual potential customers.

Clicks is just an easy holdover metric from the paid search side of digital advertising. It doesn't make sense in the context of early funnel ads. You need to measure the effect your display ads are having on your purchasing endpoints. Which is what the whole cross channel attribution industry is about.

Its quite possible your are getting good value from facebook ads, you've just inadvertently focused in on the worst subpopulation, the clickers.

The problem with the article is that the author draws a conclusion with far too little data, akin to signing up for NetFlix and saying it is a terrible service when the first movie doesn't buffer fast enough.

I've spent mid six-figures on Facebook CPC ads over the last several years and can definitively say that they work very, very well - depending on your use case. Mine is not the OP's use case (though I've sold a metric a-ton of SaaS on FB).

I advise everyone here thinking about FB ads to do the following:

- If you try it, dedicate a serious amount of money. Nothing less than $500 will suffice as you need to get statistically significant data across all your targeting sets.

- Focus very narrowly on your target market. Trying women age 22-29? Do that in your metro area only. Keep your targeting sets small so you have fewer variables to contend with.

- Don't lose your nerve. If you give up too quickly you'll know nothing.

Finally, I do understand the OP's frustration with click numbers from FB vs. GA. Don't let it get you down, as this is common on every platform. Optimize for your actual logged data and you'll profit.

I think the evidence of something being wrong is very compelling. But one of the problems I see is that if Facebook even attempts to fix the problem, their revenue drops by 30% and investors/advertisers sue for fraud.

They're in a tough spot. But they should at least start to turn the ship in the right direction before their total ad business collapses as "ineffective".

hagbardgroup 2 days ago 2 replies      
Oh boy. Another one of these posts.

While you can self-serve advertising, it is not necessarily a good idea, in the same way that representing yourself in court is not necessarily a good idea.

Facebook cares much less about fraud than Google does, because FB has been under much less external pressure from shareholders to do it. That is not to say that various Google properties do not have fraud issues still. This is reflected in the price differentials.

After all, entire IPOs built around Adsense fraud occurred in the mid-2000s. There have been countless small businesses built around link fraud. It is quite likely that some of the major media names built on social traffic are also based in part upon defrauding social advertisers, because as of yet, few have cared about it, and many investors will just reward companies based on trivially faked traffic metrics.

But guess what? Circulation fraud is a problem that has been with us for over a century in media. Some combination of the price system, auditing, direct response ad testing, corporate incompetence, the good ol' boy network, and other methods have kept it from making advertising either totally useless or totally risk free.

Despite this, here are some issues that could help you advertise better in the future:

1. This is not a good ad. The copy is bad. The illustration is bad. The call to action is unwieldy. The logo placement is haphazard. The headline is Wrong. The human figure is in the wrong position. The button placement is haphazard. You would be better off plagiarizing ads from Mint and swapping out the logos and colors. If you want to keep the lady accountant mascot, put her to the left of whatever copy you want the visitor to read, and make her look at it.

2. The demographics you selected might as well have been at random. Market research is not throwing a dart at the entire planet and targeting whatever the dart landed on.

3. FB != Adwords in the same way that a newspaper != the yellow pages != a niche interest magazine != radio != flyers != e-mail spam != direct mail != a catalog and so on and so on and so on.

4. Your budget is so small that it barely qualifies as a test campaign. You ran a test campaign and discovered a hazard to avoid. That is the point of the early tests. If you run out of budget before you can discover a profitable marketing strategy, your tests will uncover that you are out of business.

In this case, you are dazzling yourself with your measurements because it is easier for you to do so than it is to think at a higher level about your objectives and the methods that you want to use to achieve them given your resources. You could call this Silicon Valley Degenerative Metrics Dementia. Sadly, there is no known cure for SVDMD.

I could personally care less if Facebook goes out of business, but as long as real people with wallets continue to use it, it will have some utility to advertisers, so long as they put forth at least some good faith effort to control their bot/fraud/misclick problems.

Considering some of the things that I have seen with Facebook, I am not confident that they really care, because many investors will reward them when they count bot users (or human users living in third world conditions) as if they were humans with first world bankrolls. There is no comparable Matt Cutts figure for Facebook. I think the real money on the platform, like was the case with Google for a long time, is on the criminal side.

Hopefully some short sellers are paying attention to these stories, because terror is the only thing that will induce Facebook to stop its absurd gyrations on the product side and actually police their platform. Short sellers can orchestrate a PR campaign and either pressure Facebook to start caring or can just make a lot of money by torpedoing the firm through aggressively publicizing its failures.

All that being said, I hope that this is helpful to you, and I am glad that more businesses are learning that online advertising is difficult, complex, and risky (like advertising everywhere and always in all mediums over all time periods using all sorts of technologies).

CPC is just the wrong model for Facebook. It turns into "spray and pray". In this case, nobody is looking for a personal budget app, it just shows up uninvited. Whereas with Google, we know someone is likely looking for it when the ad appears.

How much of Facebook's traffic is mobile these days? I personally prefer the desktop version, but I spend unhealthy amounts of time at the computer anyway. I know that my mom uses FB almost primarily through her iPad since she got it.

If FB's traffic is almost or even largely from mobile devices, paying to show ads for a non-mobile site to that traffic seems just silly. The site is downright hostile to mobile users; the text loads last, it starts with a video and a worthless image, and the actual text ping-pongs across the page to accommodate the clip art and screenshots.

Given this exact same data, the OP could spend a week making at least his landing page mobile, run another FB ad, and make a blog post about A/B testing your landing page for mobile users. But no, it's all Facebook's fault, because bashing Facebook will always, 100% get you upvotes on this site...

The article raises some great points and it's very frustrating to read these articles as the founder of a Facebook Ads Optimization tool aimed at SMBs (AdEspresso - http://adespresso.com - Shameless plug :P).

I'm not going to say that copy was not good or that the number Facebook tracks are correct. I find the copy of the ad used pretty good overall. However I've some consideration about it:

- I totally agree that Facebook must improve its tracking and must do more to prevent clicks fraud ... a problem which is still very relevant

- Lot's of Facebook Ads traffic comes from mobile nowadays. This can be good or bad. If you're promoting a website and aiming at conversions on a non mobile-friendly website you MUST disable mobile targeting.

- Overall $50 budget is not enough to get to any relevant conclusion.

- On a product like this (budgeting, finance, etc.) it's critical to find a very good audience to target. I'd suggest using a lot custom audiences.

- Facebook Ads bounce rate & overall quality is very often lower than Google, Yahoo & Bing, this is implicit in the nature of the platform. On Google you're getting traffic from people who are actively searching for a keyword strictly related to your product. On Facebook you're targeting people based on demographic profile and a vague interest. However Facebook is very often much cheaper than Google.

- CPC & CTR are meaningless metrics. You should always have conversion tracking and measure the overall CPA to acquire a customer. Click frauds, wrong reportings etc. ... they exists. You cannot do anything about it. You should not give a crap about it. Just check your Cost to acquire a customer and see if it makes sense.

- Sometime for some markets Facebook Ads for direct conversions simply don't work. Create valuable content like eBooks, webinars etc. to get cheaper leads and then close the sales funnel with targeted emails.

My 2 cents, hope it's useful for someone :)

YMMV, but as an anecdote my wife's FB CPC campaign for her new private psychotherapy practice saw a > 2% click-through rate to her PsychologyToday page, and the number smust have been close to real because they led directly to phone calls from prospective clients who confirmed they'd seen her ad, deliberately clicked it. It took her maybe 6 weeks to fill her schedule and she turned it off.

Note a photo of a smiling female is the best creative for CTR, and narrowing the demographic in her use case was simple: females within 15 miles of her office, aged 25-45, in certain income range. We think the average lead who actually called probably saw her ad 6 or 7 times before clicking.

OP may have valid criticisms of FB ads, but in our case it was a massive success. Spending a couple bucks to acquire a client w a LTV over $1000 is a no-brainer.

Again, YMMV but if you use it right FB can be a fantastic tool.

I'm getting fed up with these post saying "Media X" is bad (where X is usually something to do with Facebook or Google display).

Two comments:

1. This media is sold in an auction. If the quality of the traffic vs what you pay for it is bad value then the bids are set too high. If I pay over the odds for something on ebay it isn't just ebay that is at fault.

2. Doing online advertising well is harder than Facebook and Google are incentivised to make clear. In some cases this stuff is very hard which is why there are people whose full time job it is to get it right.

As someone with some expertise in biddable media reading posts like this must be like a coder reading about how a programming language is flawed because the Todo app scaffolding doesn't quite do what the author expects.

I don't know enough about your business to know whether you will ever get a positive ROI on Facebook ads, but a clear call to action and more targeted copy will have a world of difference in terms of conversion.

Compare the author's: "Easy to use, free online budget" to"Scared of being in debt? Get your FREE budget report instantly. Click here to request info."

I'm not saying that's the ideal copy, but you have to get people's interest and explain more. Make it specific to a location like "Virginia" or "Sydney" or "Melbourne" or "Kentucky" and target those specific places you'll get a higher CTR and conversion. The mobile vs. desktop part is a whole other discussion.

I just tested the water with Facebook Ads for my startup AppBlade.com as well, budgeted some $500. Did my best to target mobile application developers, this was my exact experience. Thousands of clicks, not a single sign-up. Also the CPC was higher than Google for our keywords.

Google in the same timeframe has had a measurable ROI and is converting at ~10% for us; even mobile clicks.

This is just data, it's worth experimenting for yourself but I definitely feel that something sketch is going on. Make sure to use utm_ codes and something like MixPanel so you can track the originating source for your paying customers.

Running a 60$ is nothing on FB, you need to run volume and optimize.

My very rough and sloppy analysis gives you a credible interval of a conversion rate between 0.28% and 5.61%. At the upper bound of that conversion rate (5.5%), I would handwave and suggest this is comparable to your Google CPC results (depending on the actual cost per click). If I were you, I'd collect more data.

And try different ad text. Acknowledge that this is a different platform than search and you need to advertise differently. Don't be so quick to dismiss it.

Edit: and I was comparing apples to oranges anyway. If I use your Google Analytics data for both measures, we get a range of 0.39%-7.7%. This upper bound actually exceeds your Google CPC result. You don't have enough data.

I've had good luck with Facebook ads. I think the targeting is key. If you target people who are already familiar with your brand, it helps a lot. You can target, for example people who already "Like" your page. And you can target their friends as well. Facebook also has a feature that lets you serve ads to people by their e-mail address.

If you stick with those, you're pretty much guaranteed to be targeting real people, and not bots or fraudsters.

Also, learn to use the Facebook Power Editor, as you get a lot more control over how your posts appear, how your ads work, etc.

Desktop and iPhone traffic are better converting than Android traffic, so advertisers bid higher to display on these platforms.

For this type of website, he should be bidding desktop - will pay maybe 40% more per click, but much better site engagement.

FB Ads still have a long way before the tools are as robust as Adwords, but learn the platform and run more tests before you trash it. Unless you're going for something ultra-targeted it's rare to nail a CPC platform on the first go.

Interesting post but it's hardly news, a few years back when facebook was struggling to make money I remember reading a detailed article about how facebook delving into advertisement could mean the end of the web as we know it and by that it meant the end of ad-supported websites.

First facebook ads would drive online ads pricing towards the bottom, then it would make obvious something almost all of us know: online advertisement is mostly an overpriced scam that doesn't work and most netizens despise.

Then the usual business model to support costs for running a website would crumble and disappear.

Sadly I can't find this article now (thanks to google tweaking its search engine, it's now hardly possible to find an old results or anythine relevant past the first half of the first results page), but I remember it pointed out that facebook users are much less receptive to ads than google search users. People using a search engine are actively looking for something and ads can be actually be useful to them, but for people looking for social interactions with people they know ads are quite useless and an annoyance.

Right now facebook lack of transparency and accuracy in their ad business means more profit and less trouble for them while hiding the elephant in the room, so don't expect the situation to change soon unless they're given incentive to do so.

People with no idea of how to run ad campaigns should not be bad mouthing X ad platform.

There are so many ways this post is wrong. First, a .4% CTR for a newsfeed ad sucks. That means either your demo targeting sucks, or your ad sucks, or both. Second, if android visits don't convert, change targeting to desktop visitors only. Third, traffic sources behave differently. You can't jump to the conclusion that they're scamming you just because one traffic source worked and another one didn't. Another possibility is that you haven't tried hard enough.

I used Wave on a number of projects as well as some of the biggerish discussion "waves" back when it was still with Google.

For the projects, it was awesome. This was a long time ago, so I don't remember all the excruciating details, but it made coordination and collaboration on big documents pretty trivial. We also had some group messaging and file-storage accounts that went virtually unused because of Wave.

Our use-case was in writing large-ish documents (a few hundred pages each) as a committee. And it was pretty trivial to just create a wave for each section of each document, then use top level comments in the Wave for each subsection, and capture everybody's brainstorming for each section. It was like a living collaborative outline that eventually filled itself in and turned into a section. We used links off of the discussions into Google docs for collaborative editing of the documents and when we felt everything was good, somebody would simply go in and copy-paste all the text into master good doc for final cleanup.

Having worked on similar projects in the past, coordinating this kind of activity with email and word docs (or even google docs) is a huge PIA. When we decided to move it to Wave for a small trial (to figure out the workflow) it was pretty trivial and sort of worked naturally. There was a minimum of document syncing issues, or confusion about who said what in which meeting or email. The entire past history of discussion, with threading and everything was open for review. It was amazing despite many of the obvious issues with the Wave client.

The big discussion "groups" on the other hand were mess. It was impossible to find where new comments in old threads were posted, and once the conversations got big enough, the UI slowed to an unusable mess. Wave didn't last long enough for anybody to figure out how to deal with this.

Outside of those two use-cases I really didn't use Wave for much else. I suspect I would have found other uses as time went on if it had survived (and especially if it had flowered and federated).

I've thought long and hard about why Wave failed and it really does come down to 2 things:

- lack of focus

- poor user experience that never seemed to get any better

Wave tried really hard to be all things to everybody, with some really neat tech demos to show use cases (arranging a group meeting by embedding a poll and a map etc.). I think it was kind of like the C++ of communication mediums. It's sort of everything, but you can only realistically use some subset of the functionality in practice and the parts you don't use just end up seeming useless and weird.

On the user side, carving out just the functionality for your use-case was also hard. And the slow as syrup client really was a huge turn-off. Weird, non-standard scroll bars everywhere (which never got fixed and never worked like anybody expected), nobody liked real-time global echo as they typed (brought about by a confusion of how IM actually worked in practice), and way too many half-baked widgets and bots and things.

I think Wave should have simply focused on a few simple use-cases, nailed and refined those, then grown all the other awesome ideas organically so the user-community could start to slot those into their workflows.

Wave might have worked better if it was launched simply as a threaded messageboard with real-time replies showing up in a post. Users would have also needed 1 more layer of organizational abstraction, a "Wave container" to carve out different groups of Waves. In my use-case above we really needed to have a container for each document, with each Wave for each major section. But in the most general case, a "pg" type person could have created a "Hacker News" container, and each submission and comment history would have been the individual Waves.

When Wave launched, everything was a wave and there was no way to organize them, so people ended up using top-level comments in the waves as the "topic submissions" and the Waves went on for thousands of comments across dozens of topics before they started to break. It just wasn't a good organizational metaphor, but the system and the client didn't offer a good alternative.

Then the client was clunky and slow, nothing else on the web felt as slow even with such little graphical sparkle. It was basically a side-by-side email client by look, yet acted like it was folding proteins or mining bitcoin in some worker thread.

The crucial tactical error the Wave project made was not integrating with existing systems like email and chat. This forced people to either jump fully onboard with Wave or ignore it. Predictably, when faced with an ultimatum like that, everyone just kept using email (and IRC and wikis). If the Wave team had instead spent a fraction of their development efforts on seamless integration with email, IRC, and other relevant protocols, even at the cost of some simplification of Wave itself, the project might very well have been a success and more advanced features could have been added later once adoption picked up.

The current Apache Wave code base is a vast complex tangle (GWT wasn't the right decision, I doubt web sockets was either), and there's virtually no life on the developer list.

To be in any way seriously useful, this should be reimplemented as from scratch with a strict separation of UI and wave server back end, with a massively simplified deployment process. (Go would be a good choice imho).

The ideas behind wave are interesting, but the technical debt that Google dumped out when they abandoned wave is so massive, I consider the current wave code base a completely lost cause.

Seriously; interested developers drop into the mailing list form time to time; look at the code base, then run screaming. The reports barely even get done.

Back in 2009/10, we ran our startup primarily on Wave for several months. Several of us found it very useful; I thought it was a promising combination of email, Google Docs, and chat. On the other hand, the usability was horrible and it was ridiculously buggy; several people hated it with a passion.

I can see why Google gave up on it but it's disappointing that they haven't incorporated these ideas into other products. And it doesn't seem like Apache Wave ever gained enough momentum to move forward.

What other projects are looking at similar chat/email/collaborative editing hybrids?

My opinion of where Wave went wrong is that it was completely non-extensible past a couple of fairly limited extension points. You couldn't build brand new real-time applications on top of Wave.

What they should've done was simply expose their real-time technology stack, then let people create documents backed by whatever (sandboxed) Javascript they want. When you open a wave, the Wave client would download the relevant Javascript, then use that to generate the user interface for the document, while managing the complexities of operational transforms and federation itself.

I used Wave quite a lot, it was great to arranging meet ups of groups of people as you could all have an active conversation and use the "Poll" widget to say if you where coming or not.

I also used it for other things, but organising groups of people was the main use. Once it was discontinued I tried to run the open source version, but it was never really that stable and in the end we swapped back to emails.

It's a great shame to see this dead

I created one of widgets that launched with Wave to use VOIP services to make a conference call from inside the gadget.

Part of me wished it stayed because I had a single letter user id.

Anyways, meeting minutes were something that it did well in my observation. Liveblogging was also interesting with it especially if you had maybe 2-3 editors and everyone else was view-only. Live tweeting events is rather feeble compared to what could have been done with Wave.

Serious question: Am I a bad person for closing the tab as soon as I noticed that the first sentence is missing a verb?

Programming is all about details, and I guess I see it as a strong signal if a project can't get details right on their landing page.

On the other hand, maybe this unfairly biases me against projects maintained by non-native English speakers. And even among native speakers, perhaps I shouldn't be biased against people who choose to spend their time on pursuits other than writing perfect English.

I wish it could have become the email replacement it wanted to be. It suffered greatly, though, from higher latency, intermittent bugs, and lack of (very) widespread adoption.

When you actually got on it after reading all the praising reviews and begging for invites on googlewaveinvites.org or whatever shady site you stumbled upon, it was a massive anti climax. Sure, it looked really good but it felt so... I don't know... void?

I think we all just wanted to be part of the "Google Wave croud" and the hype was more of a focus than the actual product. Thinking about it, I don't even remember what Wave actually was or why Google dismissed it.

I've often seen hypercubes pictured or described like this: http://en.wikipedia.org/wiki/File:Hypercube.svg

...which doesn't really explain much. Then I saw this animation of a rotating hypercube and suddenly it made so much more sense: http://en.wikipedia.org/wiki/File:Tesseract.gif

The takeaway for me was that, in that static depiction, the inner cube is a cube, and the outer cube is a cube, and each of the six (apparent) truncated pyramids is also a cube, just a visually distorted one. There are eight cubes in the hypercube and each shares a face with six others, just as the six squares in a cube each share an edge with four others. You could have told me all of that and I wouldn't have understood it, but after seeing the animation I was able to work it out for myself.

Obviously if the download page lists them I check against those, but in most cases it's insufficient because that page is not HTTPS.

Maybe some NetSec guys could answer this please. What would happen with his update to Notepad++? Would it still update the package?

Even if the target set his computer to auto-update (or something that did not require admin authentication), wouldn't he have some type of notion that something went wrong during his update?

With the target being an InfoSec guy, I would've imagined he would at least be running some type of network monitoring, like wireshark or little snitch, ESP on his personal computer. Wouldn't he have to authorize the outgoing packets?

Sorry, if I come off analytical to the story...it's a great read...I just want to make sure my networks are locked down. I've even went as far as dedicated networks for my server and home usage, and preventing internal ip addresses from communicating to each other (sucks for airplay).

First thoughts: I like it, it will be interesting to see what the typography community has to say. Slightly off topic, but it's funny how Comic Sans, a font, has become so widely hated and mocked even among non-tech savvy people. There seems to be a tipping point where something becomes cool to hate. It's absolutely impossible nowadays to use Comic Sans, even if it's completely appropriate for the situation, without being mocked by people who have never used anything else but Times New Roman.

Hi

You will notice some issues if you use Windows Chrome, which doesn't render TTF well, particularly italics and obliques.

The fix for this is to include SVG font files. I excluded SVG as they're 'advertised' as only existing to support legacy iOS. Today I found out that's not entirely the case.

As for licensing, I provide the files for free for now and state on the site 'No attribution acquired'. I'm being vague because at this point I'm undecided whether to start selling it or not.

A way for employees to push back against their coworkers when they email too much crap to too wide an audience. In other words, I wish my Inbox had a little voting widget next to each message:

    +------------------------------------+    | 4,376 people received this message |    |                                    |    | [Cool, it was ]   [It was a waste] |    | [important and]   [of my time to ] |    | [worthy of our]   [  read this   ] |    | [    time     ]   [   message    ] |    |                                    |    +------------------------------------+
Then, as votes are collected, the sender (and maybe everyone else) gets some kind of feedback on how their message was received. Maybe the report could include a total of how much time was spent reading it: "Your coworkers spent a total of 36.4 hours reading your message. It cost the company $1458 in employee time. Sending it was therefore a moderately bad use of company resources" .. or, if the voting was favorable, "1722 of your coworkers enjoyed reading your message. When you were deciding whether to hit Send or Discard, you made the right choice in clicking Send."

Edit: As I've said in the past when posting ideas on HN, if you think this is worth doing, please run with it! I make no claim on "owning" the idea, and all I ask is that if it makes you a billionaire, you commission of bust of me to install in your parlor. (Bronze or marble only, please.)

A solution for the "too many tabs open" problem. Need a way to save my history in an organized and interactive manner, with a nice looking UI. Sort of like the old WebMynd (http://webmynd.com). I find that most of my tabs are open as a form of reminder. If I close it, I'll forget it and might as well not have seen it. Same if I hide it away in some kind of bookmarking app. I think it would be best to apply a UI layer over my entire history in a way that makes it easy to search and recall things that I found interesting int he past.

Need to store all data locally for privacy reasons, and have a way to logically group urls by content and bring them back to the front occasionally (maybe with some kind of gamification?) so they don't disappear.

This is less an idea, more something for someone to think about.

We need to figure out how to defeat the internet echo chamber effect.

Notice how often, when a community gets started between a small group of people(such as early Reddit or HN), it's a place of intelligent, productive discussion, where people measure what they say instead of just spouting extreme rhetoric?

Yet, once these communities grow, you inevitably see the "How bout dem Cowboys" problem, where it seems like the point of discussion is more to get the most approval instead of trying to argue a point, and where anyone with a disagreeing opinion feels unwelcome even if they're willing to put a lot of effort into their response?

I haven't quite figured out how to solve it, but I really want to. I've been a part of several online communities like that now, and it always ends up the same way. Once it gets big enough, finding good conversation gets very rare.

I want to search for furniture, and other products, based on dimensions. My girlfriend and I furnished a new apartment recently, and had to be space conscious.. This spot next to the couch could fit a 10" wide table. It's not easy to search for that, yet the information is there. My original plan was going to use the Amazon API and take a search term and page through looking for dimensions that fit. I still think it's a great idea, but obviously not huge, and I don't really have time to build it. If you do, hook me up.

I have a strange fascination with knowing exactly how I discovered a particular artist, film, website, etc.

I'd really love a browser extension that could keep track of how the user reached a given site. Then they could go back later and input, say, a YouTube URL, and it would show exactly what lead them to that song.

I started writing such an extension myself, but I was clearly out of my element. So when Mozilla shut down their Firefox Add-on Builder, I lost motivation completely. For someone with experience created extensions, though, I imagine this would be pretty straightforward.

EDIT: no, using the browser history is not good enough. Browsing is a non-linear activity (especially with multiple tabs open), and to visualize your path through the web you need a graph, not just a list of sites.

Idea: Airbnb for food. An app where you buy meals cooked by your neighbors.

I see two big trends these days.

1) People seems more willing to connect back with their neighbors and community.

2) People have less time but want to eat more healthy.

Imagine this scenario:

While going back home, a student could check on the app what's available to eat for tonight. Next to his place, there's a family willing to sell the extra tacos for a few bucks. The student would then just stop by and pick them up.

Obviously, there would be quality rating and the possibility to reserve a few days in advance.

I've been having this in my mind for a while:

A nice way to organize & share my knowledge. I know that lots of people have a self-hosted wiki or similar where they write nice tricks, something that they learned about and might be useful in the future, nice ideas...

Well, I'd like something like this, but more "social". Pages could be shared (or public), anyone could write a comments on something (I'd love to see comments a-la Medium), and it would be nifty to have a way to "fork" and submit a pull request for every page.

I guess it could also have the usual "follow user" that will show all of his pages in a dashboard, a "trending pages" for the most seen pages and similar.

A programmer social network. I find myself with two distinct sets of friends on Facebook: my tech friends and my normal friends. With my tech friends, I just want to post neat snippets of code as statuses and share github gists on walls and whatnot. So I'd like basically github with more social elements thrown in.

Imagine seeing a cool repo, then being able to friend the owner, and open a chat box to have a quick chat about it right there on the page rather than having to go to another communication method.

EDIT: I know this super similar to github. Really I just want github to implement the equivalent of friends, chats, and public profiles people can post things to (a la facebook wall).

Fair warning, I'm kind of a sarcastic person, and most of my ideas tend to reflect that...

If you actually want to work on one of these, go for it! Just please let me know as I'd like to hear about it (and if you'd like, maybe help out where I can). Contact details in my profile page.

My three latest ideas with variations:

#1: Kitty cooker social game (please don't actually build this): Basically Cow Clicker meets prisoner's dilemma. Everyone gets a cute little kitten. In order to earn in-game currency (find a synonym for "cat poop" for a currency name, please), you must cook your friends' kittens. Your friends cannot cook your kitten if you have cooked theirs first. If all of your friends decide to abstain from kitten cooking for the day - you either all get gold, or all of your kitties get cooked anyway. In game currency can be used to buy cat clothes, cooking paraphernalia, recipes, etc. Recipes are a tradable item, effect earnings, might cost resources to use, and have a "cool down" period. Variant: Puppy kicker.

#2: A toolbox of satirical marriage help apps. I really don't have a lot of tool candidates, but they're easy to think up. For instance, "argument score keeper."

#3: Rent-a-sheep (name taken, needs something else): Presale of wool from individual New Zealand sheep. I live in New Zealand. There are lots of sheep here. Imagine a site where the landing page is a paddock of little fluffy sheep trotting around (SouthPark style animation, maybe?). When you click on a sheep, up pops a bio showing a photo of an actual sheep, from an actual farm in New Zealand. For a fee, you can "rent" this sheep, thereby receiving its wool production from that year. In the mean time, you'll get little auto-generated notifications about your sheep, perhaps including photos. You should also be able to choose how the wool is processed. That is, scouring, dying, spinning. All to be done in small batches.

Much easier variant: Small-batch customized supply chain for New Zealand yarn sold to yarn stores in the USA (aka create your store's own brand of yarn). Interface looks a bit like a slot machine - choose type of wool, then choose scourer/washer, then choose either/both dying service and spinning service.

Both variants should be very "connection" focused. That is, if you're renting a sheep, the site should do everything in its power to make you feel a connection with that sheep. If you're a yarn store owner, you should know a bit about the people who are performing each of the services, and you should hopefully have a window into how they're processing your yarn.

Keep writing is something like Medium but it allows someone to post text (news, fiction, stories, anything) that is not complete. Writers set a (hidden) number of votes they should reach before they keep going then they publish what they currently have.

How about a program that watches for certain input patterns, takes calendar, location and maybe camera data to determine the best times to deliver push and email notifications without interrupting.

Maybe one could figure out moments at which the user would be interrupted the most, for example shortly after opening a new window or tab, or shortly after switching programs, since these moments are risky for forgetting things (if the same psychology applies): http://www.tandfonline.com/doi/abs/10.1080/17470218.2011.571...

It would probably make sense to prohibit interruptions during intense writing. I also thought about an option to blacklist certain apps or websites like Skype, Facetime etc. and to whitelist activities that dont require focus like browsing news websites or playing a game.

A search engine for knowledge and facts.

I think there's huge value in a search engine of knowledge and facts, where all sources are verified. A search engine that is objective and contains no opinions, crappy blogs or tweets, content farms. A search engine where you can't game your rankings through SEO techniques or through higher add spend.

Google is amazing. Google Search is going to be here for a long time. I doubt anyone will be able to come up with a solid replacement. But one of the current problems with Google is that they have too much information.

So far, i've put together a tiny version of this concept, which i've found very useful when i'm trying to learn new things or do some research. I would love to see some smarter people turn it into something more.

The message writer sends the messages and the site takes a cut of the payment.

This is a service, it is not an i troduction or dating or real friend site.

Telepresence for travel. One use case is that I don't have time to travel to location X, but would like to be part of a group who is hiking, etc there. Could see this being quadcopters with cameras with dual controls (remote for me and possible to be overridden by someone on site if there is an issue).

Second use case is my disabled daughter who I can bring back videos of places to, but it's not quite the same as sharing the moment, and of course would give her a sense of freedom to be able to zoom in and look at something I might not have thought to capture.

Given connectivity issues to many of the places I know "I" would like to be able to go to virtually, I suspect part of the problem will be convincing folks that it doesn't ruin their wilderness experience to let other folks attend virtually. Given that you would then have fewer travelers impacting the environment I would consider this a net win.

My idea for a text editor:* storage: wiki text files + embedded git repo* save all to a single file, but with possibility to access and edit the contents via web server / web app * possibility to squash all edits and send a clean copy (branch) as an attachment * possibility to incorporate changes sent back, thanks to DVCS* two edit modes: WYSIWYG and markdown style for experts * two client modes: standalone with thick client (based on Webkit) and html5 client* possibility to access and modify the contents via APIs (Java, Ruby, ...)* optimized for screens, not for A4 / US letter pages

Manual route planning for walkers/runners/cyclers.

My idea was that there are lots of fitness style apps that track where you've gone, how fast and so on, but I haven't seen anything that lets you plan your route out beforehand, see how long it'll be and then estimate how long it will take. I was thinking drawing a simple overlay on a map interface. I recently got back into walking/running and wanted to slowly ramp up what I did, but wanted a route I could get all the way through (not run until I can't, then have to still get back) so wanted to plan ahead, and also allow for cuts through parks, bush trails and so on.

For contrast, if I'm skimming through an article, I can quickly scan for keywords, look for paragraph breaks & sentence breaks to get the gist of what a particular section of the text is describing.

How can I skim a video the same way? I'm more interested in a solution for a 30 or 60 minute recorded lecture or conference keynote than something that let's me skim a music video or blockbuster movie. So the solution here may be more suited to one form of video than another.

https://skimo.tv/ seems to be trying to hit the mark, but from what I've seen, they've got a long way to go. And I'm not 100% sure that pulling a few short video segments out of a long video is the solution.

Would be community created content, but needs some sort of community voting/moderation system to surface the best content and empower the most knowledgable/trusted contributors.

Ideally this would be where you go when you see sensationalist headlines in popular science magazines -- here you can find out what the study actually means.

Anything like this out there?

Im having trouble organising the information I consume. I have tried using a mix of Google Bookmarks, Youtube's watch later, GDocs, Evernote, Pocket, Dropbox (for pdfs/books) and tldr.io.

There has to be something that encompasses the full 'learning process': find content, read/watch/listen it, summarise its most important points, list actionables, revisit it in the future...

This maybe too personal to standardise, but even a 'convention over configuration' approach would keep people like me from feeling stuck.

Crowdbetting/Crowdtrading (etc)

A sports betting website that uses crowdsourcing to make the best bets. As a user, you predict the outcome of some match, but your final bet isn't necessarily what you chose, but what the crowd data indicates is the best bet.

Much like the CIA found crowdsourcing to be very effective in forecasting global events (http://www.npr.org/blogs/parallels/2014/04/02/297839429/-so-...), I think there's a good chance you could successfully crowdsource things such as betting on sport results.

The way the CIA thing works, I assume (the article doesn't get into much detail), is you have 3,000 people, you ask them to make some predictions, and in the end you select the top 1%. When you compare the future predictions of these top forecasters with those of CIA analysts, you find that the average Joes tend to be more correct (even though they have less information than the CIA analysts).

So you can do something similar with sports betting. You have a group of top forecasters and their predictions for some game assume some probability distribution (like, 30% bet on the home side, and so on). By comparing this distribution with the average odds set by the major brokers, you can identify where the odds have been set incorrectly (according to your crowd) and exploit these weaknesses. For example, let's say that your crowd says that the odds of the Away team winning should be 2:1, but the brokers set the odds at 4:1. Then, this would be a good bet to place, assuming the crowd is 'more right' than the brokers.

It would be cool also to have just 'a show main highlights of the game'.

Prices per game should be relatively cheap, like 1.99 or 2.99; except some cases like championship finals.

I would try first to secure the rights to show some of the European soccer leagues and championships as they should be easier to get than any of the main American leagues. Hopefully none of the US networks have an exclusivity agreement.

An idea originally by sdrothrock which I've been thinking about for the past few days: An app which can be trained to recognize certain sounds. You record a few examples of that sound and then it listens and gives an alert when it hears it.

Another idea, allow deaf people to "visualize" sounds. Just displaying the raw sound wave is too redundant and difficult to interpret. But what if you could display a higher level representation, perhaps obtained by unsupervised learning.

Even cooler if you can attach rough labels to the sound like is done by some object recognition systems (example: http://i.imgur.com/anp7RY9.png).

The second idea is probably unrealistic but the first is possible.

The idea is that brick-and-mortar stores/restaurants/hairstylists/etc that are located close to one another can communicate and coordinate days of the year (or month) when everyone in the area who is participating offers some sort of discount or sample.

It incentivizes consumers to make a day out of going to an area of town that might not otherwise get a ton of business.

Could lead to an interesting community of people travel around the world exploring and going to FootTraffic days.

A matchmaking service for business owners to digital marketing and/or web development companies.

A business owner is not going to know everything that the digital company is explaining to them or selling to them, and since there's no large digital companies that are the gold standard, but just a very fractured industry, it's hard for them to really know what they're getting.

The matchmaking company would advocate for the business owner. The matchmaking company would really understand the web development and digital marketing landscape, but they are not selling the services themselves. They would ask the potential agencies the really hard questions that the business owners wouldn't know to ask on their own.

Uber for delivery via drones. Kind of reaching, and I know it's not practical yet, but the general concept is cool. I wouldn't be surprised if Uber did it themselves first since they have a knack for trying weird delivery stuff like ice cream or flowers or whatever.

You would open your Uberish app, punch in the weight of what you need delivered and where to deliver it to, it would give you an estimate, and come to your house to pick it up and make the delivery. Really not that far off, I believe the FAA has or is relaxing the rules on commercial drone flight below 400ft and the Parrot drones are capable of following waypoints on their own to a destination, and coming right back home when they're done.

Something to keep in mind whilst sharing your idea:

Your idea may be great and may appeal to a science/tech community on HN, but be wary of building something where the audience is very small (if you plan on commercializing it).

Although quite a few of the ideas have some "mass appeal", some of them also seem so narrow that you'd be better off building them as OSS projects and releasing them into the wild (as they'd never achieve huge commercial success).

Just for the sake of guidance, plan on what you will do with any ideas you follow through with (go commercial or open-source it).

An app that allows you to have a meeting with someone anytime both of you're available for the meeting.

So it's schedule-less.

Example:

You want to talk to Paul.Paul wants to talk to you. But not as much.

Paul is ranked "a1" in your book and you areranked "b5" in Paul's book.

Paul notes that he is in a "b5 and above" time period. Maybe he just got done exercise so he is more interested in talking to anyone (you are a b5 after all). Or maybe he is sitting in the dentists waiting room and has time to kill and is ok if he has to stop the conversation right away abruptly.

In your book Paul is an "a1" so he can call in the middle of the night and you will take the call.

Paul marks his availability as "b5 and above" and then app proceeds to start to contact anyone who matches.

Someone else is ahead of you at b3 so they get the first call. Next guy is at b4 but he doesn't answer. So you are next at b5 and your phone rings and it's Paul.

You have your conversation.

Advantage: No need to schedule calls by time. They happen by importance.

With granularity on both sides.

Why I like this:

I can make the most efficient use of time. Some people are more important and you want to take the call anytime anyplace. Others are less important and you are more picky. Also ability to use time that normally goes to waste. And prevents you from having to think "I've got a minute who should I call".

What is regrettable in all this is that no one seems to consider the possibility that people may have nuanced views about gay marriage. According to the mob you're either a saint or a bigot, and thus Eich's value as a human being was supposedly entirely determined by this one opinion he voiced in 2008.

I'm staunchly in favor of gay marriage, which I consider to be a no-brainer -- but it seems to me the motivations of Prop 8 proponents differ a lot in nature, with some being much more excusable than others in their wrongness.

For example, there are people who have nothing against homosexuality but are attached to the symbolic value of 'marriage' as a Christian institution and would be completely fine with another civil contract with the same rights but a different name. This seems to be somewhat in line with Eich's actions (I remember reading a memo from Eich stating he had no plan to amend Mozilla's gay-friendly policies and employee benefits). Although I still think this view is guilty of being wrongly attached to outdated models of society, this is not nearly as bad as what Eich has been accused of.

There are other possible reasons one could have (for example, those who in ignorance of the many studies that showed that children of homosexual households grow up just fine could have unfounded reservations about gay adoption, but would be ready to change their mind if shown the evidence; I've encountered a couple myself), but my broader point is that there is a huge range in the degree of bigotry between those who voted Prop 8 and one should not jump to conclusions so easily as they do not all deserve the same level of condemnation.

Now, I can understand why Eich's views could make him unsuitable as a CEO because, in a purely pragmatic sense, holding views that most of your workforce despise is obviously detrimental to your ability to lead and especially so at such a peculiar organization as Mozilla where ideology matters arguably more than in other companies; it also matters because, as many have said, a CEO is the face of the company and his views and those of the company are sometimes hard to disentangle.

But going from there to making a call to boycott Firefox is a huge jump and smells like a pure appropriation of the controversy for PR purposes. This revelation about Sam Yagan seems to strengthen this feeling. Come on people, we're better than this. Being on the right side of history about an issue does not automatically waive us from intellectual rigor and moderation.

As for okcupid occupying the moral high ground, I still remember when, right after their purchase by match.com, they removed one of the most interesting posts on their blog. It was about why you should never pay for dating web sites and why paid dating website were not worth it. As with all of their blog posts it was backed up with data and evidence.

After the purchase and change of monetization model, poof! it was gone. Why? because it was rightly critical of match.com !!

So, bottom line: Eich was forced out by an astroturf campaign led by professional boycotters (waving the gay rights flag this time) and sleazy opportunists/publicity addicts like Yagan.

If Eich is a homophobe, I would like to replace the rest of the world's homophobes with him. While he may have disagreed in private, his public persona was inclusive and friendly. There are multiple testominies from people that never knew he harbored wishes to limit their rights before the controversy came out. Even the LGBTQ* Mozilla employees/volunteers spoke up to say this. Meanwhile, in Montana/Utah, if the CEO learns you're gay, you're likely to be found dead in the middle of the night.

But the mob had already formed, and they wanted blood. Blood is what they got. And the Mozilla project suffers as a result.

The Eich story, and the lynch mob that followed it, permanantly reduced my respect for HN. While I would not ever donate to a campaign (let alone one that denied equal rights to human beings), this made the gay community of HN (and their supporters) look like easily-influenced livestock. I used to click on the HN comments link before actually clicking the story it was about, because I could rely on the spin being kept to a minimum. I no longer have that guarantee. Similarly, I no longer have the guarantee of fair discourse, and fully expect future comments to be downvoted to oblivion (much like reddit) when one has a dissenting opinion. If someone says you hate gay people (correctly or not), the HN community has proven they will prosecute before a proper inquiry has been made.

Even more disturbing, I have now learned that the militant LGBTQ* members in Silicon Valley are just as easily-influenced, and as easily driven to boycott, as members of Stormfront, or the AFA, or the PMRC. This seems to be such a big issue in the Silicon Valley that I'm now solid in my decision to stay out of SV for any new startup ventures. Intolerance (even intolerance for bigots) is not something I want to immerse myself in.

There's an enormous false equivalency here:

Prop 8 groups are single issue donations. A donation means exactly and only that you agree with the cause of anti-gay marriage.

Politicians are many-thousand issue donations. I know of exactly zero people who I agree with on everything. A donation to a politician can have thousands of motives, and even be done in staunch disagreement about certain issues (especially in the case where their opponent is the same on the issue you disagree with and worse on everything else)

On net I'm conflicted about the whole thing. But I do think that people who value tolerance should be intolerant of the intolerant.

Failing to select both boxes would bounce the user off of the OkCupid side.

Then one starts to question if being intolerant with the people that are intolerant of those that are intolerant is any better, and whether we are working in a system that allocates the call stack in the heap or in a defined stack, because too much thinking in this direction would cause a stack overflow in the JVM.

The difference between these cases is that Mr. Yagan donated to a Congressperson's election fund, while Mr. Eich gave directly to supporters of a cause many find abhorrent.

The degree of separation is important: although Rep. Cannon was anti-gay-marriage, we don't know whether that was the motivating factor for Mr. Yagan's donation. It could have been for some other reason: perhaps Mr. Cannon helped him or his company in some way, or perhaps Mr. Cannon's opponent's views (relating to things other than gay marriage) were more objectionable to Mr. Yagan than Mr. Cannon's were.

It's also important to note that this donation occurred in 2004, when few politicians openly supported gay marriage, and most publicly said they were against it.

Politicians have views on all sorts of matters, some of which we agree with and some of which we don't, and most of us aren't single-issue voters. A donation to a politician is not strong evidence of the donor's agreement with all of the views of that politician. A donation to an organization that is specifically trying to pass a law, however, is pretty strong evidence of the donor's agreement with the aims of the law.

I have no issues with gay marriage, and I don't think that individual religious views have any place in the creation of laws that will affect people's everyday lives. However, this idea that someone can't keep their personal political views outside of their workplace is the territory of small-minded idiots. A good CEO can, indeed, support causes in his personal life that don't wind up becoming policy at the company he or she runs.

See this for what it is. The left is trying to make it OK to punish anyone that has ever supported a conservative cause. Everyone should now fear that their political views will endanger their jobs. This is perhaps the most slippery of all slopes, as this marks the beginning of the end of political discourse in the US. If the right made demands like this, they would be skewered in the media. Yet, because our media has an extreme liberal bias, this has, sadly, gained traction. Just say no.

The Hypocrisy of Some Blogger

Summary: The co-founder of OKCupid made a donation to a homophobic senator in 2004.

There's a lot wrong with this "scandalous" revelation. Do we have any direct word on Sam Yagan's change of heart to support the oust of Brendan Eich? This blogger does not, from Yagan's actions we have to assume he feels differently now, a decade later.

And so, these toothless allegations of hypocrisy fall apart. This point from the rant:

> This was a PR stunt, and as I show below, nothing but a PR stunt.

The stunt had the intended result, so this statement is either false or in doubt. Or, if the stunt is unrelated to Eich's removal, then it reflects popular sentiment to boost the OKCupid brand; it's familiar bland commercialism and no kind of hypocrisy.

Everyone with strong ties in marketing world will know that dating sites are one of the most shadies businesses balancing on the line of legal/illegal.OKCupid action was blatant marketing stunt - but thei CEO is immune.No one cares what he did etc.No one on the board or anyone working for him will be approving his departure upon this news. Mozilla case is probably one of the most ethical ways to get publicity this guys did in years...

Prediction: those who insisted that political actions and professional life should be separate will call for Sam Yagan's head, completing the ouroboros of hypocrisy.

The author's basis for the claim that this was a PR stunt is that Sam Yagan made a donation similar to Brendan Eich's. Like Brendan Eich, he has the opportunity to say he's changed his mind on the issue in the years since, or provide more context for the donation. Brendan Eich's mistake was avoiding the issue entirely.

The IAC senior leadership has no (0/13) people of colour, and only one woman (thats 1/13). And in fact, they don't even have anyone who wears glasses. IAC is the owner of OK cupid, and Sam Yagan is on the parent company's wesite here:

http://iac.com/about/leadership

Google at least has a much more diverse company leadership teams. Ya know, men and women and people who wear glasses and hair color other than "middle brown".

For Yagan to take on his own Board as a subordinate, calling them a bunch of "racist bigots" --not for their private beliefs, but for their "public" actions-- as witnessed by their hiring policy, would be quite a stunt.

I don't think you get a pass on a politician with a record like this. http://www.ontheissues.org/house/Chris_Cannon.htm#Civil_Righ...

It's like saying 'well, he's a white supremacist, but he has pretty good views on economic policy!' - if those issues are important to you (and they probably should be!) it's not reasonable to overlook them. You have to draw a line somewhere, even if you are occasionally willing to ally with people you disagree with to achieve a common goal.

I find the entire Eich scandal disheartening. A man lost his job (one he was undoubtedly qualified for) because people find it easier to heap hatred on someone they've never met, than to act with dignity and respect.

We have some serious issues in this country, and our inability to compromise or respect a person we don't agree with is frightening. Life is filled with shades of grey, compromise is not "that nice thing your kindergarten teacher told you about" it's a critical aspect of a functioning democracy. One we seem to be losing.

Yagan's personal views don't really matter. In fact, Eich's views don't matter either because in politics, perception is reality.

Yagan contributed to the growing perception that holding anti-gay opinions is socially unacceptable, something that the gay rights movement has been trying to achieve for decades. Regardless of his personal views, past actions or other motives, it helped.

Eich could have easily saved himself. The key problem was the perception of an anti-gay CEO of Mozilla, and this could have been fixed in the same way that all public figures handle shifting public sentiment: with a statement about how his views have "evolved", he realizes now how wrong he was, apologizing for the hurt he caused and so on. Clearly he chose not to do that.

This is about as non as non-stories get.

For one, there's about 27 universes worth of difference from supporting a specific law which does a specific thing, and supporting a politician who has different positions on different laws. Maybe the other positions he has took priority over marriage equality?

For instance: five years ago, coming out of the economic mess, I'd have prioritized economic recovery (so, someone who knows what they're doing on that front) over marriage equality. That's not to say marriage equality isn't important, but it's all rather pointless if the economy is trashed and everything else goes with it.

No, it's not "exactly the same." I don't think anyone really benefited from this entire shit show, but stop trying to excuse and water down what Prop 8 supporters did.

Giving money to a bad politician is not the same as giving money to support a war of pure bigotry and hatred against gay people. Perhaps you weren't there in 2008, or perhaps you weren't a target. But the Yes on Prop 8 campaign deployed deeply disturbing and hateful rhetoric that relied on the worst tropes about gay people--that they want to corrupt your children into homosexuality. All this wasn't just to pass a law, but to permanently enshrine and sacralize hatred in the California Constitution.

Here's a question: many people, perhaps you the reader, oppose Eich's forced resignation because of freedom of speech concerns. Great, I'm with you! And why I think this was all a stupid idea that doesn't benefit gay rights at all. But why are we as a society up in arms about this firing in particular? Why are we not focused on ENDA, for instance, which protects you from being fired for saying you're gay? Why aren't we outraged that workers (illegally) get fired for saying they want to unionize? Or, more tech-focused, people getting fired for shit-talking their boss on Facebook? It seems that, as usual, freedom of speech is only a concern in the media if you're a rich, straight white man.

Hey, HN, CISO of Yahoo here, typing on a phone at a kid's birthday, so excuse the formatting.

We run a very progressive bug bounty program that allows bugs like this to be posted publicly. Every once in a while we might miss something out of the thousands of invalid reports we receive every month, and we made a mistake in the triage of this bug. The bug is fixed and we won't make the same mistake again. We definitely consider info disclosure to be a class of issue that needs to be addressed and to infer otherwise from one mistake is incorrect.

There are a handful of companies experimenting with this kind of open bounty model, and if we want it to survive (I certainly do) then we are going to all have to be willing to iterate to fix the problem, and move on.

I love how publicly posting bugs shifts the balance of power. "schofield" probably though it was just a conversation between Yahoo and the submitter. Now it's a conversation between Yahoo and Hacker News.

Welp, the verdict is schofield is being dense. Of course user relationship pairs are potentially sensitive. Therefore enabling attackers to discover them by enumerating your tiny key space is an issue.

Either schofield needs to wisen up or Yahoo needs to put someone better in charge of their security issues.

The collision rate seems pretty high and to someone with a bit of resources (say 500 ips) to go through the ids would take 3~ days at 1 request per second.

The party would have a list of of flickr users / email combinations.

The best way to fix this if they want to have the urls work for some backward compatible reason is probably severe rate limiting after x requests if they do not want to expire these requests -- right? Otherwise, something the size of UUID will make the search space too large.

So I clicked on one of the example invite links listed in the bug report. I was then prompted to log in to my Yahoo account. Hmm, OK... so I logged in, at which point I was taken to a page with a form asking me to join Flickr. I did NOT fill in or submit the form because I don't want a Flickr account, though it was presented with defaults based on my Yahoo ID anyway. I closed that window and tried clicking on an invite link again. Much to my surprise, the link then worked and I received an email saying "Welcome to Flickr". What the hell?

[edit: on the plus side, Flickr make it very easy to delete your account entirely. The only obvious side effect is that the screen name you had is now unavailable for any further users]

Can we not call this a "bug?" It's clearly a design weakness and "schofield" said it was working as intended, ergo not a bug, but just a poor choice of mechanism. Pretty humorous that "schofield" thought it was fine the way it is. Guess that has been cleared up by the internet. It's pretty trivial to generate a random, non-guessable, unique code to use as a lookup key for the invitation, and I guess that's what they've done.

it's really easy to capture contacts this way. As Mathias said, they have to limit the view of the saved form to the one who sent it in the first place... and add an expiration for deleting such data.

So what's missing ? an ID for knowing the first sender, a timestamp, a checking process and a garbage collector to delete the expired ones periodically ? Ok, we don't add a column so easily in the big DB table here, but they can add a sister table with both IDs, the timestamp and a "IsActive" boolean... and start filling the new table with no reference ID, so only the timestamp works for the existed ones. the system will repair itself at the end of the expiration date.

I think a more contrasting approach to color is likely better - maybe you start with a green button, which goes Gray on click, and then fills with brighter green. This will avoid issues with color-blindness, or even just myopia, where people won't really see the subtle color filling in.

Why have a progress bar at all? I'd rather "Submit" and... things happen immediately.

I do realise that there's probably some server-side things going on when you've submitted, but you could do that at the very last form input, and once the button is pressed, magic appears. No loading, no progress bars.

If javascript is disabled, these buttons do not work. Always need a fallback plan.

I know this is a WIP, and it's awesome. Very green though. ;-)

I used to landscape professionally. Which - in my case - is a fancy way of saying I cut grass, dug ditches, raked leaves and spread mulch. I picked up some useful knowledge along the way.

Thing is, no matter how much satisfaction I get from a problem solved, elegant or just effective code written, etc - it isn't quite the same thing as when I could look back at a yard/park/complex etc at the end of the day and say "Yep, that looks good. I did that." Something that not only I could appreciate, but everyone driving by would notice on some level.

I'd not want to go back to that full-time. Intellectually my work now is far more satisfying (mentally designing algorithms while walking behind a bobcat tends to result in both poor algorithms and a poorly cut lawn). And it's easy to forget the long days, paychecks at the mercy of the weather, being constantly sore and always finding dirt and the damndest of places...

But I am thinking about finding some part-time work in landscaping this year for just that reason. I enjoyed it, I was reasonably good at it, and it felt good to be doing. With my hands.

I've taken two separate part-time jobs while working full time elsewhere.

The first one was while I was working for the federal government. I commuted one hour each way and after spending two years in a mid-sized bedroom community I still had no friends where I lived. I got a job at a local coffee shop filling in where needed which was usually either opening up from 6 to 8A.M. or closing up from 6-10P.M.

I immediately got to know a lot of locals from the college students and young people who worked alongside me to the professionals who came in earl to the stay-at-home moms and dads that came in mid-afternoon.

I learned how to make a great espresso made some spending money and a bunch of friends. It was a great experience.

The second job was while working remotely as a developer in a tiny rural town. I took a job as a fitness instructor at a local studio and, again, met a lot of people I wouldn't have otherwise and got to make a real personal impact on many people's lives helping them get fit and stay healthy.

Excellent idea, excellent article!

A couple of years ago I was driving back to my office and a difficult programming problem which I had been avoiding. It was early fall and the weather was beautiful. On the way, I passed a field of Chile peppers and a crew was gathering to pick. It looked like so much fun to be out picking chile peppers in the sunshine instead of sitting in front of a screen in my dark office. So, on a whim, I stopped and asked the boss if I could get a job picking peppers for the day. He almost fell over in surprise but said yes, I could on Saturday which was the next day.

So, early the next morning I got up all excited and went out to the field. One of the underbosses gave me a bucket and explained in broken English how the system worked. I was paid 55 cents for each bucket of peppers and I was to leave no peppers unpicked. Ok, no problem. I was assigned a row and off I went. After about half an hour I realized my error of judgement. It was really hard work and not nearly as romantic as it looked. To make matters worse, everyone was way ahead of me and had to keep coming over to my row to help me stay up.

But I wasn't about to quit and get laughed at. So I stuck the day out and make like $40. I then went home and slept for a day and a half and could barely walk. I don't know what the point is. But this was a good article. More people should do stuff like this.

Doesn't it strike you as slightly obnoxious to take such a job away from someone who needs it? I can see this story ending up in Mike Judge's "Silicon Valley".

When the only way for you to disconnect from the work environment and get in contact with the bigger outer world is to get another job and connect to another work environment, something is definitely wrong with you! When you need commitments to other people, like a morning job, to wake up, you have an even bigger problem.

A few summers ago I lived in Seattle but worked in Bremerton, which is over an hour away by ferry. To reach on time I had to take the earliest ferry possible; at 6-something AM. If I missed that ferry, the next one wasn't until 1.5 hours later, which would make me very late.

Almost every day--like clockwork--I got up slightly late, threw on some clothes, and went out with my bike. Half-asleep, cold, and worried about missing the ferry, I pedaled my heart out through Seattle's hilly downtown streets and past morning-rush buses.

It sounds miserable. But y'know what... By the time I reached the ferry--usually with only a few minutes to spare--I felt awake, full of energy, and ready to take on the day. As someone who's usually slow and tired in the mornings, this was an immensely refreshing feeling.

(To say nothing of the commute back, biking up a series of brutal, steep-grade hills...)

I don't think this is surprising at all. You're brought up through primary/secondary education where there is a very definite requirement of when and where to be. College hits and that requirement is softened, and procrastination works out a-okay for all sorts of people. Finally, you land a tech job with flex hours and where remote is okay - suddenly you have to exercise self control in a manner that hasn't ever mattered before.

While it seems to me that the 'ideal' (hugely qualified and highly subjective, that word) answer is to practice that self-control (and with that, go through the ups and downs of succeeding and failing at exercising it), the solution that Jesse has found is effective and doesn't have too much overhead.

This is an amazing idea. I had a similar experience working cashier at a food co-op that I realized was operating in an alley beside my new apartment. Working on cash duty for 2 hours a week is one thing, but I think the most mind-blowing idea came from being a regular shopper when not on-shift. I'm a pretty friendly and respectful guy, and I like to think I treat everyone fairly and equitably, but... this job made me realize that something was amiss. When the people stocking your shelves and charging your credit card might just as easily be a professor or small business owner, a tiny behavioural toggle flips in your brain. And I found that disconcerting. I realized that maybe I hadn't been giving the other people in my community the mindshare they deserved, if that makes sense.

Or maybe, in a funny way, a member-owned co-op is a lot like open source, more than anything else. People who are there, are there because they choose to be. Maybe that's the most important thing that informs the different sort of interaction. We assume unhealthy things about people who do not choose to be serving us.

Or maybe that's not the take-home. I'm still thinking on it :)

My mom has a newspaper delivery route that she doesn't need. She uses it for exercise and spends the money she earns on her YMCA membership, which she also uses for exercise...

She was selected as Carrier of the Month one time and was asked to answer the following questions so that she could be profiled in the paper:

What do you want to be when you get older?

What to you use the money for that you earn delivering the newspaper?

What are your favourite hobbies?

What is your favourite subject at school?

I only remember her answer to the first question, "wiser."

This reminds me in some ways of John Graves. He wrote novels, most famously Goodbye To A River, but for long periods of time, he would build stone walls and houses on his farm. The physicality seemed to allow his mind time to work on the novels. I find that gardening does the same for me and refreshes me for technical work.

People are commenting that this steals a job from someone more deserving but it's not a zero sum game. By keeping his sanity through his personal way of staying grounded, he can spend more energy on his startup which very will might result in more jobs being created. This increases the benefits to the world more than letting someone else deliver bagels.

An interesting way to get some morning exercise to start your day.

I believe each person has to find what works for them in terms of getting a healthy amount of exercise. For some that involves a gym membership, fitness classes or team sports.

Myself, I mostly run and enjoy training for a marathon once or twice a year. I am thankful that I usually do not have to start work before 9 AM, which usually allows me to get a morning workout in without waking at a ridiculously early time.

I find this energizes me for the rest of day, provided I did not stay up past midnight the night before and also gives me some alone time to think about anything: Work, problems, or just plain day-dreaming.

Some people hate running for a variety of reasons and I can understand that. You're much less likely to stick with an exercise routine if it feels like yet another chore in life's long list of chores. Experiment and find some activity you can do regularly that offers more than just physical benefits.

Great article. I've been thinking in this lately. We, which work on tech, spend all of our work time thinking in how to resolve a problem. It doesn't matter if it is backend or frontend, but we have to approach a problem and resolve it. I think I am a little tired of doing this all the time. Sometimes, I wonder how it would be to have a mechanical job where I have to think less and do much more, mainly physical tasks. Your experience seems a good example of this, and I think I am going to try if I find the time.

Sounds like the OP is happy with his schedule, which is great. However everyone needs different lengths of sleep for the body to process/release toxins. For me it's 8 hours at least to wake up feeling refreshed and not relying on coffee or other stimulants to go through the day. As for waking up feeling tired no matter when, the optimal timing for waking up matters and is at the end of a 90 minute sleep cycle (you need a few of those per night). https://en.wikipedia.org/wiki/Sleep. You can also use iOS apps like "Sleep Cycle" to aid you in waking up at the right time - really made a difference for me. Waking up to a screaming alarm is probably the last thing you want.

Mathematicians find way to put 7 cylinders in contact without using their ends sciencenews.org

ColinWright 1 day ago 1 reply      
It has been known for a long time that one can arrange 7 cylinders to be mutually touching. That was written about by Martin Gardner decades ago, and was set as a puzzle.

The result had the cylinders touching at the end of one with the length of the other, so the question arose, can one arrange to have seven cylinders all mutually touching, without using the ends. The easiest way to say this is to ask for seven infinitely long cylinders mutually touching.

This has only recently been settled, hence this paper. It's believed impossible to arrange eight identical infinitely long cylinders to be mutually touching. I suspect the result is in fact known, but I haven't searched diligently for it.

There is an associated puzzle that uses cylinders that are very short - think coins. How many coins can you arrange to be mutually touching?

Consider that a puzzle. I can do 5. If you can do more, there's a mathematical paper in it for you, should you care.

The core idea of non-incremental progress: Xerox PARC accomplished what it did in large part by forcing technology 15 years into the future. The Alto, of which PARC built around 2000, mostly for its own staff, cost about $85,000 in present dollars. What it provided exceeded the general market personal computing capabilities of the late 1980s. This enabled the "twelve and a half" inventions from PARC which Kay claims have created over $30 trillion in generated wealth, at a cost of around $10-12 million/year.

Kay also distinguishes "invention" (what PARC did) -- as fundamental research, from "innovation" (what Apple did) -- as product development.

Other topics:

Learning curves (people, especially marketers, hate them)

"New" vs. "News". News tells familiar stories in an established context. "New" is invisible, learning, and change.

The majority acts based on group acceptance, not on the merits of an idea. Extroversion vs. introversion.

There are "human universals" -- themes people accept automatically, without marketing, as opposed to non-universals, which have to be taught.

Knowledge dominates IQ. Henry Ford accomplished more than Leonardo da Vinci not because he was smarter, but because humanity's cumulative knowledge had given him tools and inventions Leonardo could only dream of.

Tyranny of the present.

When Tetsuya Mizuguchi left Sega to form Q Entertainment, he and his team started work on the famous puzzle game Lumines. Their stated goal was to create a game that was merely half a step forward, as opposed to their previous game, Rez, which was two steps forward -- and didn't do well at market.

Smalltalk was at least two steps forward, probably much more than that. The critical thing that put it well into the future was the fact that it made the boundary between users and programmers even more porous. I'm sure many of you have heard the stories of teenagers sitting down to an Alto and writing their own circuit design software in Smalltalk. That kind of power -- turning ordinary people into masters of these powerful machines easily and efficiently -- is just the sort of revolution originally desired and promised us by the first microcomputer marketers.

But of course it didn't do well at market at first, so we had to settle for the thing that was merely half a step forward -- the Macintosh.

Allow me to put forward a historical analogy: standing in 2014 and arguing a case for gentle future changes in [pick your field here] over the next few decades, based on the past few decades, is something like standing in 1885 or so and arguing that speed and convenience of passenger travel will steadily and gently increase in the decades ahead. The gentleman prognosticator of the mid-1880s could look back at steady progress in the operating speed of railways and similar improvement in steamships throughout the 19th century. He would be aware of the prototyping of various forms of engine that promised to allow carriages to reliably proceed at the pace of trains, and the first frail airships that could manage a fair pace in flight - though by no means the equal of speed by rail.

Like our present era, however, the end of the 19th century was a time of very rapid progress and invention in comparison to the past. In such ages trends are broken and exceeded. Thus within twenty years of the first crudely powered and fragile airships, heavier than air flight launched in earnest: a revolutionary change in travel brought on by the blossoming of a completely new branch of applied technology. By the late 1920s, the aircraft of the first airlines consistently flew four to five times as fast as the operating speed of trains in 1880, and new lines of travel could be set up for a fraction of the cost of a railway. Little in the way of incrementalism there: instead a great and sweeping improvement accomplished across a few decades and through the introduction of a completely new approach to the problem.

Though a bit obnoxious i really liked the talk.Alan talked about 2007. If we look back it was the time when first iphone was announced. We all knew that in a timespan of seven years the processor will be much faster( Now it is almost 20 times faster)., connectivity will be faster, it will have better display and better sensors.But still none of the application that exists today (except games and animations maybe) take all this improvement into consideration. We are still stuck in old ideas of messaging app, photo sharing app, maps and news aggregators. I believe all those apps could have been conceived back in 2007. No one thought about any new use cases which can take use of the improved hardware. In fact some of the noble concepts like shazm or word lens were conceived 4-5 years back. Now we are stuck at a time where giants of internet are just struggling to squeeze few more bytes of information from user in sake of making more money from adds. It is difficult to believe after 7 years of first smartphone the most talked about event this year was a messaging app being acquired for 19 billion!!I think hardware engineers push the limits by going to any extent to make moore's law true.

However, there's one thing that really bugged me about his talk. It basically boils down to the fact that you have to take into consideration Moore's Law and have to pay a hefty sum to make any useful invention by paying for the technologies that are 10-15 years ahead of its time to do anything useful for the next 30 years. How does one "invent" in his terms today without the equity that he refers to which you need?

Great idea - good luck guys! Related note for the HN community, while we're on the subject:

Unless you have time & money to burn, you really should never never never trade your car into the dealership. It's the worst price you're going to get along the used car supply chain. And even if you think you're getting a good price, it's because you're probably pairing it with buying a car (and paying too much for the car you're buying).

The worst-case used car dealer supply chain works like this (going backwards):

* You buy a used car for $20,000.

* The used car dealer bought it from a wholesaler for $19,000

* The wholesaler bought it from a wholesale auction for $18,000

* The dealership who sold it at auction paid $16,000 as a trade-in.

(*I saw worst case because not all of these steps happen each time)

Note the chain begins with trade-in -- because dealerships know that people who are trading in are pressed for time and want a no-hassle deal. But in doing that, they're giving up $thousands to each step along the chain.

So when selling a car - going direct (or using a service like InstaMotor) is always going to net you more $$ than trade-in.

And now ya know :)

I'm in the process of buying a used car and wrote a note to my business partner about how I wish a service like this existed.

There's often a ton of communication between me and sellers to determine things like:

- mileage

- automatic / manual transmission

- whether car has been in any serious accidents

- whether there's any major upcoming maintenance

- whether the driver smoked

- whether the title is Clean

Then I need to get the VIN and run a CarProof (Canadian equiv. of CarFax).

Then, assuming it checks out, schedule a test drive.

Then, assuming the drive is good, get a mechanic's inspection done.

Then, pay and sign papers.

It's a royal pain, compounded by the fact that CL and Autotrader individual sellers seem to be a generally sketchy or uncommunicative lot: no email replies, missed appointments, lying about the title, etc. are all common.

Car buying won't be done like it currently is in 10 years from now; glad to see you're doing something to improve the experience.

1. I was looking a bit at ways to remotely unlock a car over a network connection. It seems to me that the technology story around that is a bit weak, but not completely infeasible. First, there's automatic (http://www.automatic.com/) though i don't know if they'll ever ship a product, but in theory it's really what you guys want. Second, there is a myriad of small stuff like this http://www.text2car.com/

2. I really liked the concept of being able to take the car for a drive, free of any awkward conversation with the owner. It's really pleasant actually, and it gave me the time to think about the purchase and inspect the car. The user psychology is really nailed on that one. That's the way I want to buy every used car from now on."

Long story short, Sy and Val liked our service so much that they decided to just copy it. I'm all for competition and welcome Val and Sy into the used car market. It is sorely in need of a better solution, one which will make buyers and sellers happier and eliminate the inefficiencies and scamming of the dealer model.

I'm not a big fan of plagiarism but different people are different I guess.

If you'd like to stop by our offices, meet our team and see how we're doing, just PM me and we'll hook it up. Chris might even let you drive his 500 hp formula car, which he's been building over the last couple of years! :)

Cheers,

Nicky and the Carlypso team Nicholas@carlypso.com

Most dealer trade offers are so low because they don't even keep your car on the lot, they sell it at auction...at wholesale prices.

That is a lot different than individual sales...which is how this service sells your car. So yeah, you get a better price for your car, but the service still eats a good chunk of the sale price difference between dealer-trade and individual sale.

And "all the paperwork" amounts to downloading a bill of sale form and title transfer online with the DMV. It's not rocket science, nor time consuming. Certainly not worth hundreds of dollars.

Great service! A lot of people don't have experience or simply don't want to deal with the Craigslist experience. Putting another option between a private party sale and the dealer is great.

Questions that immediately come to mind - how do you handle negotiations, and how do buyers pay? How do you pay the seller afterward? (cash, verifying a cashier's check - other comments point out the common scams etc.) (Or is Instamotor just a transaction facilitator)? Where is the vehicle listed? Do you handle smog checks as well (for California)? <- Those are the most common things I go through the used vehicle process.

Also, how do you filter out non-serious buyers, especially for performance vehicles? A lot of sellers ask for some sort of proof of payment or cash ready before a test drive. It seems like you're mainly handling high-end cars where the 5% commission will pay off too, how does the model change for say a $5K vehicle?

Finally as a buy I would want to do my own inspection unless the inspection is at a mechanic I already trust - there is way too much conflict of interest having the selling side do an inspection.

Some ways to get it more buyer-friendly would be to offer a CARFAX as well.

Just curious, I actually have a car valued at around $20,000 that I want to sell. I posted it on craigslist, and realized that I don't have time to deal with all the crap.

Some dealer called me and left a message saying that they would sell my car for me for $200. Are they lying? Are there other hidden fees? Why should I pay InstaMotor $1000 instead of $200 to this other guy?

One advantage, I see is that I get to keep and drive my car. Except my car is parked in a lot, and I only have 1 keyfob to get it out.

orky56 2 days ago 1 reply      
This is a great service. Although eBay Motors and Craigslist exist for this opportunity, they are very impersonal and create just as many issues as they try to solve. Here's some feedback on the website and service. Hope it helps!

1. Redundant content: I felt like you repeated the same value proposition in nearly every section of your website. However, each section had one small tidbit that wasn't addressed anywhere else (e.g. only available in bay area).

2. Excessive calls to action: Although it's great that you have placed many calls to action (various buttons, sliders, etc.), it really confuses the user. Having one consistent message and/or placement might improve conversion. Just a hypothesis and one you should definitely A/B test.

3. Poor navigation: The "home" button in the footer navigates the user to an awkward anchor tag on the home page. The About page has a large image that makes it seem like a homepage rather than getting in to the actual content of the page. The Contact page is an overlay modal and may not even be worth creating as a separate page. Perhaps placing it in the footer is sufficient.

4. Commas: In your slider showing the different amounts you can save, you should be sure to a comma as a thousands separator or a decimal point + "k" or "thousand". This will increase impact and hopefully conversion as well.

5. Reposition: Seeing this on "Show HN" and seeing lots of copy/images in the beginning made your site seem like it was a just placeholders. It wasn't until I scrolled to the bottom did I see there were testimonials and cars that were actually sold. This content should be placed further up since it demonstrates some form of validation/social traction. It would be great to have a ticker or some other indicator of cars sold at some point when it gets bigger.

Best of luck and feel free to reach out for any clarifications.

I like it and would like to use it here in D.C. please.

I would suggest making the sell price in the big red letters instead of the "youll earn" part. That whole section is a little confusing and I thought it was telling me I would only get 2k for my 20k car. I only really care about how much I would be getting for my car, the comparison to the dealership is important but secondary, and oh by the way I will have already probably looked that up on kbb.com.

Thoughts:

Wish it was more prominent that this is Bay Area only for now. I doubted that it would be in my area, since it sounded like something that required local personnel and nobody seems to do startups in Houston, but you have to scroll to the bottom to see it stated.

Some of the text looks terrible on my Windows 7 - Chrome environment. Especially everything in How It Works.

The website is all about the sell side, and you say the buy side is ebay, craigslist, autotrader, etc. Why not post the cars in a store on your site too? Last time I checked those sites, they had a terrible UI.

In fact, that idea expands the business from a seller's assistant kind of thing to more of an online-focused CarMax. I think that could be really useful to everyone. I'm thinking kind of a cross between AutoTrader and CarMax. On the buyer's side, it could be like the existing online sites, except that the photos and details are collected by your people, so they're consistent and high-quality. Maybe you take the car for a few hours, have a mechanic check it out, wash it, and take high-quality high-res photos in a controlled environment. The buyers can know and trust that you've done all this, and that they're getting a good representation of what they're thinking of buying.

The sellers get pretty much what you're already doing, all of the legwork done for them, a better price, and hopefully buyers who know what they're getting, and are vetted as serious buyers before a test-drive is set up.

I suppose the main difference between you and Carmax, then, is that you are all online, thus have a much better online presence, and don't need to maintain a car lot. Does that translate into enough of a cost savings to offer a better deal to the customers than the current incumbents, though?

It's a totally different business model to this but http://www.webuyanycar.com/ is a pretty big deal here in the UK. You get a valuation, take your car to them, they buy it. To my surprise it worked pretty well too and I got almost as much for my car as I'd have realistically got waiting for months on a classifieds site or whatever. I imagine the way the British used car market works has a big impact on the idea actually working though.

If someone gets in an accident during a test-drive who is liable? Do all insurance plans cover this?

What does remote-key access mean? "We verify all buyers and schedule flexible test-drives with remote key access."

How quickly do you plan on expanding to other states?

I've bought and sold a lot of cars the past few years. I have never once considered a dealer trade in offer. I've had relatively easy and good luck with selling my car online through Craigslist and Autotrader which I imagine is what they will probably do to unload the cars.

I like the idea of the service but I'm wondering what the difference is between dealer trade in pricing and market pricing. Even if I have to sacrifice a couple grand to not have to do the whole process, I'm ok with that but I'd rather know pricing from that point of view.

I'm also curious how you plan on doing the legal paperwork as I've done a lot of this too and it's not easy getting setup to handle all the paperwork especially if it's between two parties.

The way it says "you earn" I can't help but think that that is the total amount you will get. I would prefer it to say "you earn $95,000. $10,000 more than you would have with a dealership". Or something similar.

I hate selling cars. It's troublesome and time consuming, so you I'd gladly pay for the service. The pricing turns me off though. Selling a 50K car, the commission would turn out to 2.5K. That's net. So with 50% income tax rate, I'd have to earn 5K to pay the commission.

That's much too steep for me. If there was a cap of say 1K, I'd be a customer in a heartbeat. But 5K gross is certainly worth the inconvenience of selling it myself.

This post got nailedhardby the voting ring detector, but I'm restoring it because we want to see original work on HN.

A "voting ring" is when people get friends to upvote their stuff. This is against the rules. We want stories to be on HN because they're good, not because they were promoted.

It's sadly common for a great Show HN post to get demoted because its creators, eager to get it on the front page, tried to game it. I've noticed a pattern, too: usually their gaming technique is pathetic. Perhaps that's because they're creators, not promoters. Unfortunately, it has the side-effect of making it certain that the ring detector will nail their otherwise good post, while we carry on the real cat-and-mouse game with people pushing crap.

I've got what I believe will be a sweet solution to this problem, but it awaits time for implementation.

Please everybody, don't ring-vote your posts; just take your chances with HN's randomness. If a post is solid and hasn't gotten any attention yet, a couple of reposts is ok. Be careful not to abuse that, though, since we penalize accounts for reposting too much.

I'm going to demote this comment as off-topic so it won't get in the way of the real discussion. Send any moderation questions to hn@ycombinator.com.

I have a friend that is a UPS driver and he always rolls his eyes when somebody mentions this to him. UPS trucks definitely turn left. Sure the delivery order generally tries to reduce left hand turns, but on the routes that he drove he saw very little difference in the route when comparing them before this 'change' and after it. The biggest cost savings were done by reducing the driver and truck counts and paying the remaining drivers overtime to deliver more packages.

In Denmark, the term hjresvingsulykke (right turn accident) is common, meaning when a car, typically a truck, turns right and hits a bicycle. Lots of people are killed from this every year. One theory is that it is primarily foreign truck drivers who are not accustomed to the high number of cyclists in Copenhagen.

When I initially saw the title, I was expecting it to be a mistake and actually say "Why UPS Trucks Don't Turn Right". I guess the problem is less severe in the rest of the world.

The routes a mapping service like google maps will give you are not that great really, in many cases the data needed to do a perfect route are just not available. We aren't using the stats from routes in the past yet, but it's a next step that would clearly be beneficial.

Apropos left turns, former FBI director J. Edgar Hoover was involved in a left-turn accident early in his career, after which he ordered that his drivers never turn left when he was in the car.

http://www.fwweekly.com/2011/11/22/tapping-in-to-the-bureau/

Quote: "A small army of agents spent days planning details of the trip. The supervisor drove the car with Hoover and Tolson. Hoover insisted on riding in the back seat, on the right side. Hed once been injured in a car wreck while sitting in the left rear seat, and he refused to sit there again. Also, the accident occurred during a left turn, and Hoover no longer allowed his drivers to make left turns. This complicated the route to Austin in those days before interstate highways."

WebM support on 4chan 4chan.org

Has anyone had experience optimizing for webm? I really want to support this codec, but it's insanely slow in my experience. I'm finding that it's generally around 4x slower than mp4, but I've also had cases where it's taken up to a minute to encode a file where h264 take under 10 seconds.

My use case is to have the best performance/quality ratio for a 30 second video under 3mb.

These are my ffmpeg flags:

h264: "-vcodec libx264 -crf 28"

webm: "-c:v libvpx -qmin 0 -qmax 50 -crf 5 -b:v 1M -c:a libvorbis -aq 4"

The video I tested with these setting last night took 5 seconds on h264 and 35 seconds for webm, both outputting to a 2.6mb file.

System Specs:- Intel Core i7 4770 Quad-Core 3.4GHz- 16gb 1866mhz memory- ssd drive- 64bit ubuntu 12.04 lts

What further frustrates this is that I can use OpenCL to improve encoding times even more, but only with h264 in ffmpeg (as far as I know).

WebM is clearly a far inferior experience compared to gif on firefox:

- at the start there is a stupid "fade in" effect.

- the loading animation does sometimes not disappear even though the video has fully loaded.

- the loading animation is generally annoying. Gifs just stop when bufffering and continue as soon as there is new data.

- a useless control bar shows at the bottom on hovering.

- Unlike gifs the video does not stop when you scroll beyond it which causes a huge amount of processor load.

This is a very big moment for WebM. I feel 4chan has become the 'porn' industry of the internet. With VHS vs Betamax the largely deciding factor was which standard porn supported (this was again to a lesser extent with bluray).

The general lack of adoption of animated png's is often pointed squarely on 4chan. Since it generated most of the web's viral funny content. And since most of it was in .gif, who needs to support .apng?

Hopefully we will see the opposite with WebM. More general funny content, more drive for it to be adopted on sites like reddit (which already to some extent uses gifcat on some subs), and imgur. Which will snowball its general adoption.

One problem I have is that there is no way to set format priority which would override page order. And because of some Apple's stupid bugs in Safari most pages list mp4 first. Current Firefox already supports mp4/H.264 through gstreamer, so it always picks that first even if WebM is available.

I'd prefer to set some option of "free codecs first".

WebM is a fantastic step forward. I prefer gfycat links over imgur gifs when browsing reddit (gfycat is a service that converts gifs to WebM). It does have minor teething problems (controls, loading animations, etc) but its advantages outweigh its negatives.

WebP however for some reason hasn't gained as much traction as WebM. Firefox refuses to merge support, despite the fact it leverages the same library is WebM. I'd like to see WebP gain support more than WebM, Google's mod_speed converts images to WebM if using the Chrome browser to save on bandwidth.

My father isn't a HN regular, but he's 70 and is very much a hacker. He founded a software startup (www.imatest.com) when he was 63, and now has a dozen employees and is working harder than ever as its CTO. His passion for hacking hasn't waned in the slightest -- if anything, it's increased by orders of magnitude since he retired from his day job. His hacking aptitude within his own narrow speciality (imaging science) also seems to be undiminished.

I do sometimes notice that the breadth of his hacking aptitude might be less than in a younger person; he doesn't always grok new concepts as quickly when they are outside his immediate area of interest. Eg., it took me a long while to convince him that automated testing was a really important part of modern software development. But I can understand how this would seem quite alien to somebody who first learned to program on punch-cards -- and since he's happy to delegate things beyond his immediate area of focus, it hasn't been a problem.

So, anecdotally: medical issues permitting, there's absolutely no reason you need to scale back on your passion for hacking passion as you age, although the breadth of your hacking might need to narrow somewhat.

If anything, programming has become more important to me as I have gotten older, for the same reason that mathematics has greater appeal to a maturing mind -- it represents a rational counterpoint to a world that, over time, seems to make less sense.

While surely there are few hackers older than 60 or 70, the history of the personal computer is still too young for the question to be a meaningful indicator of how long people keep hacking. The Altair came out in 1975 meaning that someone that was 20 at the time and started hacking on it right away is only reaching 60 next year. The first mass-market personal computer (the Macintosh) came out in 1984 and working with computers was still a niche at that time. Those hackers that are over 60 now are either super early adopters or those that started hacking late in life, so in any case a very small group. I'm sure there will be plenty of hackers over 60 in a few decades :) - Also, looking forward to fragging and playing Starcraft in the nursing home! :)

My father-in-law retired at 75. He was writing firmware for Perkin Elmer chip steppers. I've seen his code, it was pretty nice stuff.

One guy I met was 65 and about to start up another company. He was sharp and definitely knew what he was doing.

The group I was in at Microsoft (Xbox) had David Cutler in it; I think he had just turned 70. I didn't work with him closely, but he was definitely prolific (also more than a bit controversial, politically, at MS, but he had mellowed out quite a bit when I met him).

58, been very active on HN since the beginning, 7 years ago.

My passion and aptitude for hacking are higher than ever!

I struggled all day yesterday, trying to organize parameters to feed an engine to propagate data that would generate code for a new project. Woke up at 4 a.m. with a hypothesis, and built a working prototype before breakfast. What a great day already.

I have written over a million lines of commercial code since 1979, still work serving customers pretty much full time and have enough time left for another 20 to 30 hours per week on personal projects. I have at least one or two more start ups in me, for sure.

If this industry was like it was when I started, before PCs and the internet, and I had to sling COBOL for enterprises, I'd probably be a greeter at Walmart now, planning for social security. But fortunately our world has changed and it's so much more interesting and fun. If I ever do retire, I'll probably still keep building stuff forever.

The 2 best things: software is everywhere and involved in everything now. I can't imagine not finding an interesting application. And perhaps more importantly, things change so fast, there's always something newer and possibly more interesting right around the corner. (I wish I had more time to explore node, go, and some more frameworks, but I'm so busy...)

Between building software, riding my bike, drinking great beer, and getting laid every once in a while, I still feel like 25. I don't want it to ever end.

I think anyone who builds software should feel like I do. I hope most of you do. Prepare for a nice long ride!

I started age 19 in 1967. Maybe even earlier. Dropped untrained into the deep end commissioning 4100 computers at Elliott Bros near London, and turned out I could swim. Passion - always had the feeling of "You actually want to _pay_ me to do this?"

Now I am 66, still fully employed, latest thing you might have heard (of) is the WiiU Audio engine. For unrelated reasons I went through a battery of cognitive function tests a couple of years ago and came out sharper than I was at 19 by at least a full sigma. I have no plans to retire.

I would add Don Knuth to the the honors list. And Minsky. Tony Hoare. Ted Nelson. Alan Kay. The original Homebrew Club members are getting up there. And about 100 others I know but you probably won't recognize. A peer group in which I am merely average.

As to selectivity and numbers. Yes, there have been programmers since WWII. But mot that many. So my age group has far fewer members than the upcoming geriatric programmer generation. But I have noticed one very encouraging feature we share: barring serious health issues (and even in spite of in some cases), a high percentage are still very active and passionate. No comment on causality, could easily be that it takes a active mind of a peculiar bent to get into the field in the first place and these just last, or it could be that the mental excersize it takes to keep relevant keeps the mind young, or both. But I'm pretty sure I won't last long if I have to stop doing it.

My father probably qualifies too. In the early 80's we had a Bell Labs/Western Electric Energy management system with home sensors and links to the electric and gas companies. They used a Z80 microprocessor in a STD bus card rack. And at no point in the last 30+ years has he ever been without projects or machines to work on.

His skillset goes from the EPROM and PLC level, through C/C++, and on to actual 20 ton open die forging. I've seen him take a break from debugging a C++ driver for a hydraulic beam loader to replace live high voltage fuses with a hot stick rather than wait for the power company. It really puts what we refer to as 'full-stack' into perspective.

I'll be 70 in November and am putting the finishing touches on a VST plugin that can make any 'phone (head, ear, canal, etc.) I can measure sound like any other 'phone I can measure with remarkable verisimilitude. The trick was not the DSP (standard stuff, that, and part of what I once got paid to do) but in devising a measurement system that worked across types. That part was empirical and took more years and iterations than I'll admit to but without retirement I wouldn't have had the time for all the experimentation that finally nailed it.

I've got to say that my coding bug rate seems worse and debug time seems substantially longer and more tedious than I remember. My first coding was assembler for an IBM 7094 as a student at the University of Illinois some 50+ years ago. Been doing it ever since.

BTW, I'm looking for someone that can transfer the tech to a paid Android app. Somebody 70ish would be way cool. Kernel level audio skills a must for global filter insertion.

Listening to good jazz helps to stay in shape(there's some scientific data that proves music activates something in the brain, not sure what exactly, but it seems to work :-).

As someone noted earlier in this thread, there's nothing new in programming for the last 30-40 years. You just need to learn 100 tricks, you learn them early, and then the age makes no difference. What changes is that you don't think of career any more, and think about money much less, which makes you a very bad candidate for bullshit work. You can imagine the consequences.

John ffitch.

I was lucky enough to be taught by John. He believes he may have been one of the first people to make computer music - spending precious compute cycles at Cambridge with a speaker hooked up instead of an oscilloscope.

He's ~69, and last time we spoke a few years ago, he and some peers were still writing and selling their compiler product (http://www.codemist.co.uk/index.html), John was still active in the Csound community (C dialect for computer music), and dabbling with computer algebra.

Having known John outside of lectures (and meeting him at the age of ~58), I'd say he has a childlike fascination with the world - constant curiosity and a lot of enthusiasm. And also understanding that computer science is cyclical, that rediscovery is part of life, and he could add deep experience each time around.

I can't speak for myself I believe I have worked with some contributors to LedgerSMB who are retired.

In general, I think one has to be careful about making generalizations here regarding aptitude. LedgerSMB is hard to get into because with ERP/Accounting software the domain knowledge requirements are significantly higher than the fluid intelligence requirements and domain knowledge increases as we get older. In LedgerSMB I have generally found that older programmers contribute better code than younger programmers precisely for this reason. Some of the biggest bugs we have ever had (the ones that caused us to pull 1.2.0 and 1.2.1) were caused by overlooking a critical part of domain knowledge.

So I dont think things get particularly worse. The fields of excellence may change however.

I'm happy for anyone who is productive past normal retirement age, but it's important to be aware of what happens to our minds as we get older. I think the examples in the comments are exceptions that prove the rule. The reason for the dearth of older hackers is the same reason there are few people running marathons at age 60 or 70: As we age, our bodies and minds degrade. Exercise, nutrition, and (probably) drugs can slow the decline, but we don't yet have the technology to turn back the clock.

The most depressing graph I've seen is figure 1[1] in Images of the Cognitive Brain Across Age and Culture[2]. It shows how our cognitive abilities decline soon after we reach maturity. Starting in our 20s, we lose about 6 IQ points per decade; more in our 70s and 80s. That means someone in the top 1% in high school (IQ 135) would be down to average intelligence by the time they were in their 80s.

On the bright side, the decline in raw cognitive horsepower is offset by gains in knowledge. In fact, knowledge more than offsets it in most disciplines. Our peak productivity is usually in our 40's and declines much more slowly than one would expect[3].

Still, if you want to keep building cool stuff when you're older, it's important to prepare now. The best thing you can do is stay healthy and active. To return to the marathon analogy: A 55 year-old might not set a world record, but with the right training, nutrition, and possibly performance-enhancing drugs, they can beat >95% of people half their age.

Finally, to everyone mentioned in this thread: Well done! I hope to follow your example.

this is interesting, but in a way it's also really scary from my quick look at it it seems that is sql to store the emails. any reason to use that over mbox, or milder, which you can then easily index?

it also implements a small imap client(which may work fine for just reading gmail, but imap is a scary thing, everyone uses it a little differently)

https://github.com/naspeh/mailr/blob/master/mailr/syncer.py

that said i guess it's a nice example for writing a mail client in python.

you might want to use mailpile which had it's first release a while back:

http://mailpile.is

but even for that, if you don't care about fancy guis, you're probably still better off running mutt, imap, mu on a shell you have somewhere

edit: i didn't pay enough attention, as was mentioned it's using imaplib, which is the same library offlineimap uses. i do believe though that a lot the work that happens is how people deal with the rfcs. i remember reading about frustrations of the offlineimap author with different servers, and clients. but basically imaplib itself is just a basic protocol implementation, everything else happens on top of it.

and while you can indeed easily store your terabytes of data in postgresql and you can easily setup full text search, it's still much more portable and easily to handle backup and syncing purposes in different formats. Archiveopteryx looks interesting though, so thanks for the hint. if i never write a service to handle mails for other people i'll revisit it.

At any rate it seems like a more viable (for me option) than eg hacking on prayer (because, I think it's just silly to try and work with something exposed to so much bad user input/data as email -- in C):

Is it bad that I'm just as insulted by the so-called "spider trap"? It's so technologically simple as to be useless against anyone who could deploy a web scraper in the first place.

I mean, it's marked by comment tags that say "spider trap" right on them! Its the worst type of disambiguation system: likely to generate false positives, unlikely to catch real violators.

Reporting the content since site is down:

Tl;dr: researcher is browsing source code of a research paper's web page and finds a strange link (but same domain). She clicks and is informed that her IP is banned for automated spidering.

Apparently, this research site is meant to be open-access...

-------

Pandora is a researcher (wont say where, wont say when). I dont know her field she may be a scientist or a librarian. She has been scanning the spreadsheet of the Open Access publications paid for by Wellcome Trust. Its got 2200 papers that Wellcome has paid 3 million GBP for. For the sole reason to make them available to everyone in the world. She found a paper in the journal Biochemistry (thats an American Chemical Society publication) and looked at http://pubs.acs.org/doi/abs/10.1021/bi300674e . She got that OK looked to see if they could get the PDF - http://pubs.acs.org/doi/pdf/10.1021/bi300674e - yes that worked OK.

What else can we download? After all this is Open Access, isnt it? And Wellcome have paid 666 GBP for this hybrid version (i.e. they get subscription income as well. So we arent going to break any laws

The text contains various other links and our researcher follows some of them. Remember shes a scientist and scientists are curious. Its their job. She finds:<span id="hide"><a href="/doi/pdf/10.1046/9999-9999.99999"><!-- Spider trap link --></a></span>Since it's a bioscience paper she assumes it's about spiders and how to trap them.

She clicks it. Pandora opens the box...Wham!

The whole university got cut off immediately from the whole of ACS publications. "Thank you", ACS

The ACS is stopping people spidering their site. EVEN FOR OPEN ACCESS. It wasn't a biological spider. It was a web trap based on the assumption that readers are, in some way, basically evil..Now I have seen this message before. About 7 years ago one of my graduate students was browsing 20 publications from ACS to create a vocabulary. Suddenly we were cut off with this awful message. Dead. The whole of Cambridge University. I felt really awful.

I had committed a crime.And we hadn't done anything wrong. Nor has my correspondent.If you create Open Access publications you expect - even hope - that people will dig into them. So, ACS, remove your spider traps. We really are in Orwellian territory where the point of Publishers is to stop people reading science.

I think we are close to the tipping point where publishers have no value except to their shareholders and a sick, broken, vision of what academia is about.

UPDATE:See comment from Ross Mounce:The society (closed access) journal Copeia also has these spider trap links in its HTML, e.g. on this contents page:http://www.asihcopeiaonline.org/toc/cope/2013/4

you can find

<span id="hide"><a href="/doi/pdf/10.1046/9999-9999.99999"><!-- Spider trap link --></a></span>

I may have accidentally cut-off access for all at the Natural History Museum, London once when I innocently tried this link, out of curiosity. Why do publishers booby-trap their websites? Dont they know us researchers are an inquisitive bunch? Id be very interested to read a PDF that has a 9999-9999.9999 DOI string if only to see what it contained they cant rationally justify cutting-off access to everyone, just because ONE person clicked an interesting link?PMR: Note - it's the SAME link as the ACS uses. So I surmise that both society's outsource their web pages to some third-party hackshop. Maybe 10.1046 is a universal anti-publisher.

PMR: It's incredibly irresponsible to leave spider traps in HTML. It's a human reaction to explore.

I work for a (non profit) journal publisher and we do indeed cut off robot downloading but not after one click of a link. We analyze traffic to determine robot downloads. I suspect though that the whole entire university did not get cut off in this incident. Usually it is on a per IP basis and unless the University proxies all of their journal traffic through a single IP which is not common I think saying the whole university being blocked may be an exaggeration. I personally wish we had no robot monitor but then again we would get heavy spidering then of large files.

Sigh, did no one notice that the link is in a <span id="hide"> ? Look at the style sheet and note that class 'hide' sets the link to be the same color as the background (it makes it invisible to humans) and yet it got clicked on anyway.

There are bad actors out there, they exploit services, and one of the ways the services detect them is to create situations that a script would follow but that a human would not. When they do something bad you've got a couple of choices, cut them off or lie to them (some of the Bing markov generated search pages for robots are pretty fun))

So she sends an email to the address provided, they talk to her, she gets educated and they re-enable access. If it happens again the issue gets escalated. Its the circle of fraud.

Michael Lewis: shilling for the buyside? scottlocklin.wordpress.com

drcode 2 days ago 5 replies      
Yeah, Michael Lewis' recent interviews do seem a bit suspect. He is yelling "Hey joe sixpack, Wall Street is eating your lunch!" and then when you hear the details of the supposed "fraud" it all revolves around companies like Goldman Sachs (who work with Katsuyama) whining that they're not getting a fair shake in the world. (Oh right, Goldman Sachs is managing Joe Sixpack's pension fund via two levels of indirection- Oh noes, poor Goldman Sachs!)

Plus, the interviews he's given on 60 minutes and Fresh Air never once mention the terms "market order" or "limit order". If you don't explain those two basic terms at the heart of the HFT controversy, you're not giving people information, you're only giving them disinformation.

That said, there's obviously lots of shady ass shit happening on Wall Street every day, but Michael Lewis is not helping the situation one iota, from the looks of it.

elecengin 2 days ago 10 replies      
I think "shilling for the buyside" is a bit strong. Lewis aggressively pursued a compelling and simple narrative in a market that doesnt have an easy story. I get the impression he didnt even recognize that the field he decided to plow was a minefield. The HFT debate is complicated and has serious implications: his treatment didn't respect it.

From acquaintances that knew Katsuyama personally, he was described as a genius marketer, not a technologist. Before even Lewis came along, he had crafted a large part of this narrative: the Thor matching technology succeeded on a compelling story. Lewis got sucked in.

The personal reactions you may have seen (William O'Brian on CNBC) are authentic: HFT participants (and those who deal with them) have been villified in an industry already viewed in a negative light. There are some bad apples, but there are also many who genuinely believe that they are doing a service for the market.

I don't blame Lewis for this. I just hope that there is an author that can create a compelling story that doesnt fall for the tired trope of the evil HFT trader. The story exists - it is just very technical and nuanced at times. Unfortunately, many HFT participants have been shamed away from standing for what they believe in so there are very few left to tell the story.

If you want to read a rebuttal and learn more about the markets at the same time, check out this analysis by Larry Tabb - a market research consultant prominent in the US execution technology market:http://www.scribd.com/doc/215693938/No-Michael-Lewis

The market exists the benefit for the 'buyside' e.g. people who own stock, not for the benefit of the middlemen like exchanges and HFT marketmakers.

You may not like homeowners and think some of them are or should be convicted, but it's ridiculous to say someone is 'shilling for homeowners' when they point out that real estate brokers are overpaid and skimming.

http://blogs.hbr.org/2014/04/high-frequency-trading-threat-o...

In a nutshell, people who run big portfolios don't want to give away information about what they're doing, and they don't want HFT types to be able to pay exchanges to get first crack at front-running them.

On the other hand there is a legitimate market-making function, and there's a tradeoff between transparent markets and forcing people to share info that lets other people trade against them.

matthewmcg 2 days ago 2 replies      
I am still reading the book, but it seems like Lewis' main criticism in the book (vs. interviews) is against the so-called HFT front-running of orders that get routed to multiple exchanges. He is careful to distinguish market-making/liquidity providing functions from the multi-market latency arbitrage and spends a good part of Chapter 4 exploring this distinction.

Perhaps his public statements in interviews haven't been so nuanced.

Also, these rebuttals to the book don't really address the front-running issue. Is it simply an unavoidable consequence of the physical reality of separate markets? Should anything be done about it? Is it even still occurring or has competition among HFTs and savvier buy-side order routing eliminated it? I would like to read a rebuttal that discusses this.

This was a great article. I started reading the book. Early on, one of the examples given was "Brad talked to a friend of his at SAC Capital" about how HFT firms were taking advantage of information in the markets.

That is the kind of unintentionally ridiculous anecdote which undermines the moral center of this book. SAC Capital, after all, is the same fund which ran into one of the largest insider trading cases in history, which is also about taking advantage of information in a, let's say, special kind of way.

I know a lot about this subject, probably too much to let the judgment fall cleanly in one camp or another on HFT, but with all the hubub right now, I find it might be useful to get biblical for a second - let the person who is without sin cast the first stone.

tpeng 2 days ago 1 reply      
People ITT are not making a distinction between different types of HFT. Katsuyama and Lewis do not criticize all forms of computerized trading, but specifically computerized scalping that is aided and abetted by exchanges. Their chief complaint is that HFT uses more current prices than the exchanges themselves and they use this to scalp other traders.

http://www.zerohedge.com/news/2014-04-03/bats-admits-ceo-lie...

This is actually very simple. Natural buyers and sellers do not need intermediaries, but intermediaries do need the natural traders. So if the natural traders can coordinate, they should be able to set rules that favor themselves and disfavor intermediaries. I won't say that what HFT does is "unfair" (capitalism does not contemplate fairness), but I think it's highly ironic that HFT and their supporters are complaining how "unfair" it is that natural traders are working together, and yes, marketing their new exchange.

You don't have to agree with Michael Lewis' views or buy into the story line 100% in order to enjoy the book. The fact is that this is a well-written book that is full of mini-stories and anecdotes that present very realistic descriptions of how electronic markets and Wall Street in general work. Statements like "the market is rigged" are obviously over the top but that doesn't mean that the book on average is not true to reality. Most books about electronic trading suffer from extreme sensationalism, poor writing, and the inability of the authors to understand the subject matter that they are writing about. Michael Lewis does a better job than everyone else. He is a great writer and he is a smart guy who has some financial background and has a pretty good understanding of financial markets. Yes, there is some sensationalism here (he has to sell a good story after all) and there are many errors in the book, and, yes, the author's biases are quite evident, he's picked a side and he's sticking to his story. On aggregate, though, this is probably the best book about the world of electronic trading that I've read.

(Some people mentioned "Dark Pools" by Scott Patterson. Although also interesting, that books was often quite painful to read because it was quite clear that the author did not understand basic financial and programming concepts. "Flash Boys" is much better, in my opinion. Although if you are really interested in the subject, you should read both.)

I was thinking the intra-day gains Federal tax rate would be 50% and sub-second capital gains Federal rate would be 90%, but these values are arbitrary.

For both new types of capital gains, LIFO trade accounting would be used.

I haven't read the book, but I've followed the chatter and have been listening to Lewis on Bloomberg. I get the impression that many justify HFT by comparing current or past alternatives, however his argument is that HFT is corrupting an otherwise fairer market place. In other words the market should improve and lessen these side businesses that victimize participants and add to the discredit of the exchanges.

If anyone thinks that these side business do not victimize participants you should look back to examples like Knight Capitals glitch that most certainly caused retail investors to lose trust and pull their money from the market, taking a loss. The introduction of non-relevant code is an unnecessary risk that does corrupt the system and does victimize your average investor.

This is the only way that permissions should be implemented by any mobile platform. Without it, users are forced to decide at install time whether the payoff of having the app installed is worth the associated risk of granting ALL permissions the app requests. It's a hard choice to make before you've even installed the app.

This is great, more developers should think this way. When I worked on Google+ Developer Relations this summer there was no way to do incremental permissions, but it has since been added and makes Sign-In With Google way less scary for a lot of use cases.

Android needs this desperately. One of my apps has ~15% of users never updating because I added an additional permission and when you do that you can't auto-update. I wish I could just ask for it at runtime, since it's a Camera permission and I added picture-taking to my app. I'm sure 100% of users would say yes at that time.

Part of me worries that an app could use this in a bad way as well. If an app asks a user for a permission, and the user says no, the current expectation is that they won't be asked again. However, with this pattern, the app could bother the user until they finally gave up and granted permissions. Of course, this could also backfire and cause the user to uninstall the app.

I'd be interested if anybody also analyzed the permissions for social accounts (Facebook, Twitter).

Our experience at Theneeds is kind of strange in this regard. We have the "classical" initial join page with social buttons, and we ask for permissions when the user tap one of them. Surprisingly, we realized that many users click on Facebook icon, but next they "Don't allow" permissions. This forced us to implement a web fallback to still be able to authenticate the users (without forcing them to go to the iphone settings).

If you can make your users feel more comfortable about the legitimacy of your app and help them to feel more at ease with giving away those permissions, then you're doing a good job.

It should have a prominent link to the latest changeset     with a date or age.   * Project wide search: issues, code, wiki, discussions   * In fact, remove discussions completely, everything should be an issue.

I haven't looked closely -- my assumption is that despite this string of announcements we are not really any closer to simply running pkg_add or apt-get to install a real MS development environment (i.e. not Mono). I could be wrong though, of course.

Part of the confusion is the confusing terminology. "Shader" is a bad name. How do you "shade" a vertex? That implies color, when in fact vertex "shading" is really about deforming the position of vertices. It has nothing to do with color!

"Vertex program" is a better term.

That brings us to "pixel shader." That's actually a good name in order for beginners to learn the concept, but it's imprecise. OpenGL insists on calling it a "fragment program" because with certain forms of antialiasing, there are multiple "fragments" per pixel. "Program" is also a better name than "shader" because there are things you can do per-pixel other than change the color. For example you could change the depth written to the Z-buffer, or you could cause the pixel to be skipped based on some criteria, like whether the texture color is pink.

Anyway, it's just a tiny program that executes either per-vertex or per-pixel. For example you could write a vertex program which moves each vertex in a sinewave pattern based on time. Or you could write a fragment program to change the color of each pixel from red to green and back based on time.

Then there are more advanced/recent concepts like a "geometry program," which lets you generate triangles based on vertices or edges.

Sometimes I wonder if it's overly complicated, or if the problem domain is just complicated. It took me years as a kid to finally grok this, but once I learned it, it turned out to be very simple. Honestly it wasn't until I got up enough courage to sit down with the OpenGL specs and read through them that everything clicked. They're dry reading but not difficult.

Nice, thanks a lot. Great animations.

"Shader" was a term I was confused about at first when I was learning WebGL. In fact, in the WebGL world, it seems like one is expected to come from an OpenGL background and be familiar with whatever popular 3rd party libraries are en vogue. I never found a thorough guide that didn't presume one of those two things, so I built one:

To me, the thing with shaders always is: I need them at some stage in a project. I have used them before, but too long ago to remember, so I need to look up most it. I work with it a for a few weeks. That part of the project is done and I move on.

A year later, a new project comes along. It requires shaders. I don't remember how to use then and have to look it up again...

Repeat.

While I appreciate the effort, I think this primer is lacking what most other shader tutorials also lack: any information on how to actually do something useful. Shaders are used because they are faster than the cpu. So why isn't everything done with shaders? Because of limitations. So what are those? Most GPU tutorials only include examples of the form

FragColor = <some algebraic expression containing x & y>

That's nice, but hardly useful. To do anything of worth, I would need data from the CPU. How do I do that? What are the most common bottlenecks? What are some ways around the limitation of working with one fragment at a time? Those are the sort of questions I would like to see answered in a primer. A sort of "GPU introduction for competent CPU devs" - any recommendations?

This reminds me of a very tangible shortcoming in the OSI model that <https://en.wikipedia.org/wiki/Host_Identity_Protocol> is trying to address and which is, in my opinion, far more important that exchanging value.

It is the fact that we always talk of machine addresses, and never of machine identities (except through DNS, but DNS is also about giving human-readable identifiers, so it cannot be decentralized <https://en.wikipedia.org/wiki/Zooko%27s_triangle>).

However, now that everyone is using public-key crypto, we should understand that a machine can be referenced by a public key, and that it can prove ownership of it to anyone who asks. (This can also be used to encrypt traffic, but this is not what I am thinking of.)

Hence, why do we connect to IP addresses, rather than connecting to public key hashes? Granted, public key hashes are not routable, but there could be a service to provide the mapping from hashes to addresses -- not DNS, because it doesn't have to give human-readable names (so doesn't have to be centralized), and because there is little penalty for receiving a wrong answer (as long as you always check the identity of who you are talking to.

I think that, had asymetric crypto been in widespread use before the OSI model came about, this would have been the natural way to do things. Now the problem is unsatisfactorily solved both in DNS (which is not the right solution, as I already explained), and in an ad-hoc way with TLS, in SSH, etc.; but this is still too high in the hierarchy, machines should be addressed with public key fingerprints unless we are concerned about actual routing.

Interesting read. I'm all for decentralized systems but one important consideration which will likely be different for each scenario: is whether distributed consensus in x (ie. traffic lights, water, power) is more valuable to the participants than a statistical machine-learning based approach. The latter is optimized towards some predefined metrics (minimizing total average wait times in traffic), whereas a cryptocurrency approach is distributed to the whims/needs of independent actors ("I want to cross the street now").

The benefits of distributed independent actors is clear in some areas such as economics, where the system is so massive and chaotic attempts to control it via machine or human intervention often fail. Even when they continually adapt their models over time, they will never be a full replacement for the consensus of a market.

While markets are efficient they famously at times have a habit of acting irrational and counter-productive to participants needs. This is where in the present times human intervention (occasionally) out-performs pure markets. In the future, most of us expect machine-optimized models to out-perform both markets and centralized systems.

That may be the differentiation in the long term for which is better, which can provide the best value? Human consensus -> human consensus via machines -> machine consensus. We'll likely keep moving farther to the right of that flow as machine learning (AI) becomes better.

This new definition means, the more spam received The more my email host can raise the tariff. It can hold my incoming mail hostage.

I am very amused that people in this thread assume that this ethernet port allows tinkering with the automotive systems.

Automotive systems communicate over a CAN [1] bus, not ethernet. In fact, this bus is usually physically separated between drive-critical bus (which controls things like ABS) and "comfort" bus (such as electric window controls, central door locks, wheel-mounted audio controls). Ethernet has none of the industrial strength qualities that make CAN a valid automotive control bus, such as signal hardening and real-time guarantees.

As far as these users have found, this ethernet port is connected to the infotainment system: the 17" display.

I would be deeply disappointed in Tesla if the infotainment system can modify drive-control devices with anything less than signed binaries and commands. As an aside, I wonder what the legal requirements of such safeties are.

The cool things: Tesla is running Linux (!) and standard technologies/protocols such as SSH, NFS, X11, HTTP, etc. to do things in the car. That is cool, and probably highly efficient since developer test labs can probably just be basic Ubuntu-like virtual machines.

The sketchy things: Jailbreaking a car seems pretty dangerous, especially since as far as I'm aware, the electronic systems control things including the brake. I know this only because Tesla recently released a software update that added "hill assist" which will hold the brake in place for 1 second when at a certain incline to avoid rolling back. Imagine a malicious software update that disabled the brake! Personally, I would jailbreak a phone, but not a car. :) HOPEFULLY the system the ethernet port provides access to is firewalled out of being able to update any software (i.e. the software update mechanism is some other device), but who knows.

The phone home can also be considered sketchy, but any Tesla owner is well aware the car pings home and relays diagnostic data to Tesla. At the very least, Tesla owners know it must ping home to check for updates periodically.

If anything, I thought it was kind of cool that Tesla engineers detected it and reached out so quickly. Imagine if you weren't tampering with your car and it WAS a high-tech attacker. It is good to know that they can detect the basics.

Nice to see the Mortimer Adler recommendation as well, but I think his How to Read a Book should be a prerequisite for serious reading.

I had better jump in here right away, because the last thread about depression on Hacker News basically got swallowed up by an n=1 anecdote, and while anecdotes are wonderful (we all prefer to make decisions based on anecdotes we feel we can relate to rather than based on statistics), it takes a lot more than one anecdote to represent a complicated subject.

As my last keystrokes about depression here on Hacker News pointed out, there isn't just one disease known as depression. Depression is a symptom pattern (prolonged low mood contrary to the patient's current life experience) found often in the broad category of illnesses known as mood disorders. Behavior genetic studies of whole family lineages, genome-wide association studies, and drug intervention studies have all shown that there are a variety of biological or psychological causes for mood disorders, and not all mood disorders are the same as all other mood disorders. I know a LOT of people of various ages who have these problems, so I have been prompted for more than two decades to dig into the serious medical literature[1] on this topic. (I am not a doctor, but I've discussed mood disorders with plenty of doctors and patients.) I've seen people who tried to self-medicate with street drugs end up with psychotic symptoms and prolonged unemployment, and I've seen people with standard medical treatment supervised by physicians thrive and enjoy well off family life. The best current treatment for depression is medically supervised medication combined with professionally administered talk therapy.[2]

The human mood system can go awry both by mood being too elevated (hypomania or mania) and by it being too low (depression), with depression being the more common symptom pattern. But plenty of people have bipolar mood disorders, with various mood patterns over time, and bipolar mood disorders are tricky to treat, because some treatments that lift mood simply move patients from depression into mania. And depression doesn't always look like being inactive, down, and blue, but sometimes looks like being very irritable (this is the classic sign of depression in teenage boys--extreme irritability--and often in adults too). Physicians use patient mood-self-rating scales (which have been carefully validated over the years for monitoring treatment)[3] as a reality check on their clinical impression of how patients are doing.

As the blog post kindly submitted here points out, a patient's mood disorder influences the patient's whole family. The more other family members know about depression, the better. Encouraging words (NO, not just "cheer up") are important to help the patient reframe thought patterns and aid professional cognitive talk therapy. Care in sleep schedules and eating and exercise patterns is also important. People can become much more healthy than they ever imagined possible even after years of untreated mood disorders, but it is often a whole-family effort that brings about the best results.

> They talked extensively about how brain chemicals work and how medications help to balance out those chemicals

The only problem with this is that it's essentially a PR line that both doctors and the general public have mistaken for science. We don't know all that many facts about how brain chemicals work with regard to mood disorders. We have empirical results from clinical trials and broad use of antidepressant and antipsychotic medications, but there is no basis to believe that medications "balancing out those chemicals" serve to repair mood disorders.

If the medications helped, then great, I know they have helped a great number of people, but they also fail to help a great number more and these success stories have an unfortunate tendency to marginalize people that do not get good results from medication. It often results in victim-blaming, to make sufferers of depression wrong for stopping their medications for legitimate reasons (let's face it, all of these results are highly subjective), and for overstating the ability of our current medications to cure all mental ills.

Damn, I know of a similar story, but very different ending. I had a family member with depression try to get help. He started on Lexapro, and ended up committing suicide a week later. I had to sit there and read testimonials of people that lost friends and family attributed to taking lexapro to the mother of the deceased while she was beside herself, yet in insistent that I read.

I self medicate with marijuana. And more than just using it to make me happy, smart, excited and hungry. I grow pot medicinally as well and that makes me feel really happy. There is loads of scientific evidence that points to having a garden and lessening depression. From my experience, I can say that growing marijuana really lends itself to a lot of the benefits of having a garden. Because you can harvest 5 to 6 times/year it makes it something you need to work on every day. Progress is relatively fast, and if you do a good job, you can take it to a shop and get enough spending cash for that new macbook apple just announced. And if you are a champion, you can find your nugs in magazines. (my ghost og kush is featured in culture this month...) But ultimately nothing feels better than smoking my own herbs on Friday night after a long week of gardening and programming.

Just throwing it out there as another alternative for someone that is struggling. Been there, you just gotta find the light.

The brain is an bodily system, just like any other. Disease can strike its workings and doctors can help with modern science.

That said, we're still understanding how the brain works. One recent study showed that depression often has an associated and underlying, undiagnosed, sleep disorder [1]. Treat the depression without treating the sleep disorder and the depression comes back. FYI: This work has not been published yet.

Given that scientists have just figured out that sleep clears the brain of toxins [2], similar to the lymphatic system clearing the rest of the body of waste, these results shouldn't be surprising. We don't know the exactly reasons why people get depressed, but the evidence is clear. Depression has a root physical cause just like any other illness.

I liked the post because it shows the other side of a couple living with depression. I suffer from chronic depression and it is not easy to depend on medication every day with no prospect of "cure". The hardest part is dealing with the stigma associated with it, with people insisting that you are not doing the right thing and finding a way to get over it and free your self from medication.

I know that the "chemical imbalance" explanation is a poor excuse for "we don't know exactly how it works". But there are so many progresses done in our quality of living that were done because someone had a hunch and some practical, reproducible results showing that it worked. Think about the practice of washing hands when going from one patient to another in a hospital? When it was suggested, people couldn't see a connection with dirty hands and spreading diseases.

I lost a son that suffered from a mood disorder to suicide. It is heartbreaking and it happened when he was apparently getting over the hump of his darkest moments... I have other two children that also struggled with depression and what I found that worked the best for us so far is communication. Being opened about our struggles, talk therapy in conjunction with medication.

Unfortunately (and especially because of the evidence of the cycle that begins with "the doctor increased has dose" and "added another medication"), Wil has a pretty good chance of having a poor outcome. Especially because his medical advice seems to include the deeply problematic "chemical imbalance' theory.

Reading Whitaker's "The Anatomy of an Epidemic" (https://en.wikipedia.org/wiki/Anatomy_of_an_Epidemic) should be required for anyone considering long-term use of neuroleptics, benzodiazepines, or anti-depressants. And for those who care for them.

I cannot help but feel sorry for Will. It would be my worst nightmare to be processed by American psychologists to be placed on Big Pharma's latest medications.

The song Spaced by Beaver & Krause made this sound before THX, in 1970 on the album Wild Sanctuary

3:10 at http://www.youtube.com/watch?v=2xKO3KAtDZ0

Edit: additional wikipedia searching reveals this unsourced fact

"A variation of the end of their track "Spaced" from the Wild Sanctuary album became the inspiration for dual gliding synthesizer soundtrack for the copied THX Sound Logo in movie theaters, also for which neither Beaver or Krause were compensated."

I appreciate the level of detail the author goes to in describing the creation process. Very informative. I did this myself once, but using a patch I made in Max/MSP for drawing and listening to line segments on a pitch vs time plane. For this particular use case, I generated the input score with a Python script rather than drawing them manually. I found that detuning the sustained tones made the biggest difference in matching the original sound, which the article author mentions. Here's a video of my patch: https://www.youtube.com/watch?v=xl4C4zsy9LY

Skype as software has a lot of issues. Before they were bought by Microsoft the software worked quite well; on my Mac I'm still running an ancient version. Why ? - it got replaced by a version that takes up half your screen, I think they were trying to make a single version for desktop and iPad. After a public outcry they reduced the size somewhat. The latest version has about 3 extra options about the amount of data you will be sharing with Microsoft/associate companies. What ? I want a phone service, I don't want my personal info datamined. OK, they give you the option to disable this but it doesn't fill me with confidence.

If you want to use Windows 8 Metro version you must "link" to a Microsoft account and change your login to use that method. It's the first thing that it does, but the UI is very subtle about it. IIRC, it even wants to change your desktop login settings. Phone software should not be changing system settings. Also the latest version removes the option to hide the fact that you have a webcam. With Skype you absolutely must read all the fine print and dialogues.

I don't know, is this a problem? In some sense, it seems more honest to me than having a delete button that simply sets a "deleted" flag on you in a database.

Here's a question, would actually deleting the account lead to the possibility of someone later impersonating the original account holder? Especially since the "buddy" lists appear to be independent?

If you contact Skype's support, they can actually delete your account directly, but before they do that, they ask you to replace your profile information with gibberish.

I recently deleted my Linkedin account. But their junk emails continue to dirty my email even now. Next in the line is Skype, and then probably Facebook.

Thankfully, I never shared my genuine data with Facebook or opened an a/c on Instagram or Whatsapp ever so I'm good at a certain level when it comes to Facebook.

In my opinion Twitter is the only option that is sane at the moment.

The question I'm more interested in is why a sane delete option isn't built into the service. On the other hand, it's at least clear that your account exists forever, although it would be better if people were aware of that during sign up. Twitter claims to have deleted my account, but I cannot verify it.

As a side note, amazon affiliate accounts are equally bad.

You never put information online, delete stuff, use anonymous accounts and VPNs, yet everyone is a victim of device fingerprinting tecnhiques. That's one way the governments finds "anonymous" TOR users.

Check the online test https://panopticlick.eff.org/ and the paper https://panopticlick.eff.org/browser-uniqueness.pdf for a good read.

Maybe this is because of the way they store the data. It might be an expensive query (in their case) to search all contact lists with your skypeID, and remove it.
