This shows us, that company valuations are ridiculous and actually mean nothing.

Is SoundCloud worth a billion dollars? Well, it might be on paper or in the imaginations of the founders, but what does it really mean? To me, it's worth nothing.

The real problem is: these companies start to operate from the perspective of "having" those millions of dollars. This is why they hire too many people for too much money. They spent hundreds of thousands on marketing.

But in the end, you know what? They need to beg for money to pay their debts. They need to lay off dozens of employees because they don't have the money to pay them.

What if SoundCloud would have kept a small, yet highly skilled engineering team of maybe ~20 people, some marketing and sales, and try to not outgrow themselves? Probably they'd be having a huge surplus each year because their costs would be small and sustained.

When I read stories like these, I actually feel good about my bootstrapped, down-to-earth startup. We don't make millions, we don't "disrupt" the industry, yet we solve our customers' problems and delight them. We won't ever run out of money, as we carefully check each and every expenditure, and have growing savings in the bank.

If anybody else is also put off by the writing style: There is some actual content there. One just needs to get through the first third which basically just repeats the headline.

TL;DR (without my opinion added): Top Management started too late to think about making actual money. They also hired an asshole for their US offices. When they got an opportunity to be bought by Twitter they asked for way too much money. And the CEO is bascially on a constant holidays trip since 2014, while not failing to rub it in everybody's face via Instagram photos.

Personal opinion: I don't understand these CEOs who start cashing out before either selling their business or making it a viable paid service, while being so close to a lifetime solution to the problem of money. I mean he already went 80% of the way, much further than most.

SoundCloud could have been a nice business if they hadn't got greedy. From the beginning (or close to it) there have been various paid accounts for artists which a lot of people used. SoundCloud was the best place to discover new music from unsigned artists. There were unsigned artists with tracks on it that blew up and eventually got picked up by major labels.

But:

- SoundCloud neglected the platform.

- Then they did one of the worst redesigns of any site I've seen (try reordering a track in your spotlight [paid feature] in Chrome. Crashes the tab and has done for years. I need to open another browser to do that.).

- Then it became overrun with major label artists.

- Then they started offering features just to the big artists - various UI/branding options - (forgetting about the artists that got them to where they were).

- Then they did the whole paid streaming mess which they were never going to succeed in. Anybody could have told them that, I really don't believe anyone in that company thought 'Go' would work. I think they just needed to do something.

I'm not sure if they've taken so much money now that this isn't possible anymore but if I were CEO I would take it back to it's roots. Focus on the unsigned artists. Fix the site. Offer a distribution system (like CDBaby/TuneCore) so that SoundCloud can be a one-stop show for unsigned artists. Now you've got paid accounts (for stats/spotlight/unlimited upload space) and a small cut of distribution on all paid platforms.

I don't understand how in a world where more artists are getting big without label help nobody is offering a great platform for them. SoundCloud got very close in the past. BandCamp has gotten close too (although it lacks the social/sharing/viral aspect of SoundCloud). If SoundCloud does end up shutting down it's due to greed and poor management. Instead of focusing on what they do well and what people use them for they've tried to go after the money and they were much too late making that move to get any of it.

Never do a music industry startup unless you have a billion dollars, can raise a billion dollars, or plan to be acquired by a company with a billion dollars to spare. That's the table stakes for going toe-to-toe with the big three.

They'll bleed you to death with licensing fees, deputise you into their copyright enforcement police, upload their songs to your platform on one hand while suing you with the other, and all the while cry about how extracting monopoly profits is so much harder than in the old days.

Just go disrupt something safer, like organised crime or the international diamond trade. At least with those the law probably won't change out from under you.

Contrarian here:

Soundcloud is an incredibly valuable property. They have obviously had a few managerial cock-ups, but in reality they have massive user buyin, huge network effect, and anyone who can get some equity in them during this current time of massive negative sentiment is going to do VERY WELL. I wish I had a way to buy in at this point.

I read this article few hours earlier when crawling through the new section. It's a surprisingly interesting piece from Buzzfeed but there's a lot of bashing of the CEO, the CTO and one recently hired senior for label relations (who seem to be really odd).

This is typical: SoundCloud was an iconic company, its founders worshiped and idealized. Once money runs out, people but especially former employees start to backstab, blaspheme and blame loud and clearly. Why not before? Now when everybody is hitting SoundCloud it's easy and risk-free to join the hate. All the NDAs they once signed seem to be gone? To be fired also means fire and forget for them.

I never believed in SoundCloud. The founders did a great job building a huge brand and DNA out of nothing but the business model is by design broken or to put it simply, you just can't do business with music labels.

Btw, where is Fred Wilson? The biggest proponent and investor of SoundCloud who didn't miss an opportunity to tell us that sound is the future stays silent and hasn't commented this tragedy once. A VC just for good times?

EDIT: Why the downvotes? Mind to share your view?

I think a few things are needed in order for SoundCloud to restore some of its value:

- They need to evaluate how their (IMHO) only competitor HypeMachine does its things, and if possible consider an acquisition

- While probably very costly they need to redesign their website (and app), their latest redesign was received very negativly

This seemed to me a very sad story. The time during which SoundCloud as it was known and loved really existed was the era before they were really worrying about their "business model". As soon as they contemplated how they could exist long term, they started copying mainstream music services in a way that no-one loved. The real question is: given how much amazing free content there is, how are we going to nurture valuable cultural ecosystems like soundcloud, and create a meaningful and stable niche for them and their employees in our economies?

I used to live in Saguache County as a kid. We left in 2000 but this article does not surprise me. it is hard to adequately get across how desolate it was up there but i'll try.

We had 40 acres of land and were considered city slickers because 40 acres was enough for 1-2 cows. We were friends with people with 25k acres.

The ground was sand. 10 foot down was sand. You could water plants 3 times a day and they would still run out of water. (My mom fixed this with lots of silca gel for her garden.)

We lived on a county road and the postal service would not deliver mail closer that 2 miles away. We never did put up a mailbox and instead just had a PO box in Moffat which was about 8 miles of gravel roads away.

Annual rainfall is less than the Sahara dessert and temps would hit -40F in the winter. Some days would see 70F difference between day and night.

Walmart was 40 miles away (Alamosa in one direction and Salida in the other.)

In parts there are no trees for miles. We had ~30 trees by our house. The next ones were at another house 1/4 mile away and I believe the next were 2 miles away.

Our phone system used an antenna that looked like the old tv arials and was solar with a battery on it. (96/97 era.) We had that for about a year before the phone company decided they needed the system more in alaska and would lay phone line for free rather than charging us $6k to run the lines half a mile. Then they waited a year to come get out system. The battery on it would routinely run out in the middle of a call.

This is the worst internet in america? Wow. That is amazing! I'm incredibly impressed at how fast the worst place for internet in america is.

In highschool (Class of 2011) I dealt with 5 mbps just because my parents didn't want to pay for more. It was tolerable as long as you didn't want to watch youtube in HD. Honestly, I have little sympathy for people with 12mbps.

>This would be less of an issue if the internet werent so central to modern life. But taxes, job applications, payroll operations, banking, newspapers, shopping, college courses

All low bandwidth things. Really, you can get by fine with 5mbs. HD youtube is not a right. It's a luxury.

I live in Melbourne, AU.. 4km from city centre, in a brand new high-rise building. I pay AUD$80/mth for 8mbps down and 0.5mbps up over shitty copper that dies every time it rains.

Pings are so bad lots of services like Netflix, YouTube, etc think I can't connect and just give me "Check your internet" errors when I load, until I refresh multiple times and get it to load.

Funnily enough, our rural areas have better net than us here. I own a farm in the absolute middle of nowhere (region population of around 500) and it gets solid 24/4 and some farms nearby who face a better direction for fixed wireless get 50/8 (or something like that).

That page has a bad case of terrible website design. When I scroll down, I expect bits of image not to zoom in from the left. I nearly closed the page before even getting to the headline. They've also somehow made space bar not scroll as far as it does on other websites (in Safari), so every time I scroll down I spend a second searching for where I ended up.

At least there's only two locations of awful design during the adventure that is scrolling. Once you reach the headline, there's only one really unintuitive bit further down the page (a map of the USA), and that bit is short.

dispo001 35 minutes ago 0 replies      
I applaud the comparison with electricity. This is almost exactly how I look at it. I would compare Internet providers with utilities providing water, roads, sewage and even the post.

To think at one time we had telegraph data lines that were little more than a mud battery and a pole. The wire would run up the pole, go though a relay switched by the previous pole and continue to the next pole where it would switch its own relay. The mud battery provided very little power, just enough to switch a relay but the technology was good enough to bridge almost unlimited distance.

Without comparison with other services I would be tempted to argue my ISP provides really great services. Its 75 Euro for 300 Mbit and the package comes with a phone line and hundreds of channels of something called television.

However, when compared honestly with similar services their service is terrible. People working there told me the entire network is ready to provide 1 Gbit to everyone and the employees don't know why they didn't make the switch. I can easily guess why, I'm not willing to pay much more than 75 Euro, 3 times the speed wont bring in 3 times the money. What it will do is reveal glitches in the network that would require fixing. If I remember correctly the people who created the ISP were very passionate about the technology but ended up selling the business. Not sure if that was related but if I was passionate about my business but couldn't upgrade because of a hunger for money I would get bored fast.

Using more of this rather ignorant guess work I started to ponder how an ideal ISP should be implemented. What would it really cost? Which type of contract is best for the network rather than the user or the provider?

Surprisingly, in some areas where big money hungry ISPs refused to deliver services people had to rethink and do it themselves.

Like this one here!

http://www.buergerbreitbandnetz.de/fernsehen-ueber-glasfaser...

The "Glasfaser fr nur 9,95 im Monat" translates to fiber optic for 10 Euro (?!?)

My German almost isn't but from reading around I gathered they needed 65% adoption but got 94%, each end user had to pay 1000 Euro in advance. 900 in the form of a lone and 100 worth of shares.

To guess some numbers with that... 7 and a half years worth of 10 Euro/month does seem to add up to 900 Euro while profit made after that should increase the value of the investment. IOW, if it takes 20 years to repay the debt it would work out just fine for the investor/customer.

Some quote from speedtest: "With an average Q2-Q3 2016 download speed comparable to that in Bulgaria and Moldova, Germanys fixed broadband is slower than you might expect from Europes largest economy. At 40.38 Mbps, Germany ranks 29th in the world for average fixed broadband download speed and 72nd for average upload."

A different page mentions: "Expect a 35 bill on average for a broad-brand connection"

Most important to keep in mind, the big ISPs refused to service the area. It makes a great proof of concept. (Assuming buergerbreitbandnetz delivers 1 Gbps) in this worse case scenario 10/35 buys 1000/40.38 times the bandwidth. Or 29% of the cost for 2476% of the service. Or the 2 figured combined their service is 8438% better than the conventional urban offering.

Rural UK ISP https://b4rn.org.uk happened when big business "could" only provide crappy services at crazy rates. B4RN charges 30 pounds for 1 Gbps.

speedtest writes: "according to the Connected Nations 2015 report from the UKs communications regulator, Office of Communications (Ofcom), 48% of rural areas dont have access to broadband speeds of 10Mbps or higher."

Of course our germans and these brits had money to make their own ISP happen.

My Spanish and my Greek are even worse than my German but from reading around, apparently Guifi is the worlds largest Mesh network in Greece that originally started in Spain.

http://guifi.net/en/what_is_guifinet

Trying to make sense of this document...

https://translate.googleusercontent.com/translate_c?depth=1&...

...it seems they are actively fighting a tax per meter that guberment is trying to inflict on their fiber optic cables. If I understood correctly they are mainly offended by established businesses putting their cable in before the tax was invented. It seems big business did more than seal the ground after digging in their cables.

How different this is from the mundane consumer perspective where we all pay some corp as much as we can for as little as we would accept. We live in a world that is a bit like: when one asks why a carton of milk costs 200 Dollars the answer would be that if they charge 300 USD for it they wouldn't sell enough milk to justify the higher price.

Our entire western society works like this (I almost called it a civilization) one delivers 12 Dollars worth of labor that is sold for 40 Dollars, etc, and eventually it becomes 1000 dollars as part of a mortgage or infinite dollars as part of someones rent.

If that is the mentality or indoctrination that comes over these roads, in these letters and though this internet tube it might just be not worth having any of it.

The version of non-interactive Schnorr presented here is called "weak Fiat-Shamir" and it has led to things getting broken. While there are edge cases when it's ok to use, I would strongly discourage it.

In step 2, e = H(Q || M) should be e = H(Q || M || P). That binds the signature to the public key, if you don't have that then the scheme is not sound in the usual models (UF-CMA +ROM etc.).

EDIT: see "How not to prove yourself", Asiacrypt 2012, eprint 2016/771.

One thing that worried me a bit about confidential transactions: Bitcoin seems fairly securely-designed, but even it had an integer overflow bug: https://en.bitcoin.it/wiki/Value_overflow_incident

That particular bug seems explicitly covered by this cryptography, using the rangeproofs. But if there were ever some other subtle bug that created money out of thin air, would you be ever able to detect it? The schemes mentioned all seem to sanity-check individual transactions, and not accounts or the money supply as a whole.

The article mentions Monero and CryptoNote, for example: https://getmonero.org/2017/05/17/disclosure-of-a-major-bug-i...

And that page says: "This effectively allows someone to create an infinite amount of coins in a way that is impossible to detect without knowing about the exploit and explicitly writing code to check for it."

It seems like a formal correctness proof would be very important for cryptocurrencies with such strong privacy guarantees.

Netboot Linux over the internet netboot.xyz

I wrote Bootrino - an entire cross platform/cross cloud netboot over the Internet desktop application that supports AWS, Google Cloud, Digital Ocean. It did also support Rackspace but Rackspace is effectively dead as a cloud hosting platform and Bootrino also supported SoftLayer but I found after alot of work that SoftLayer is a very locked down environment that does not permit total control over what you run on your VMs.

Kinda takes this core concept and pushes it alot further and lets you boot from your own web servers - you just publish the (simple) bootrino config file plus the OS image and off you go, bootrino configures the instance and builds it from your own web infrastructure, be it internal or public.

You can see a demo of bootrino here:

https://www.youtube.com/watch?v=zJhxmVlR46c

The purpose of Bootrino is that it allows you to boot ANYTHING on the cloud - i.e. Unikernels and a whole zoo of other tiny operating systems, run-in-RAM operating systems, embedded operating systems etc. You are no longer restricted to running only the operating systems permitted by the cloud vendors.

Lets you do things like make RAM only Postgres databases servers, or run your web server applications purely from RAM without any login, for speed and security.

Edit: and this would be a great way to build trust, your paying customers would support the public service and distribution maintainers could get official accounts on your service to distribute to their users.

You can't do the stuff described at this site universally on any cloud due to various technical restrictions. There's certainly no standard way to do it. I even found it to be problematic on the cloud for which it was intended - Rackspace.

HOWEVER - there IS a way to boot anything at all you want on any cloud.

It's a little bit tricky.

The solution depends on the fact that EVERY cloud runs just about exactly the same version of Ubuntu. And every cloud provides a way to run Ubuntu with a boot script. What this means is in effect that every cloud has a highly standardised boot process.

So what you do, is boot Ubuntu with a script that drops the operating system, formats the hard disk and installs a new OS, i.e. a Unikernel, Alpine Linux, TinyCore Linux, Windows even, whatever you want.

I built Bootrino around this concept (see the other message in this thread about Bootrino). Bootrino is essentially a front end that boots an instance, passes in a boot script that it gets from your web server, the boot script does the job of dropping the OS, reformatting and then reconfiguring it to be whatever you want. It pulls in the OS files from any URL so it's super flexible. True net boot for the cloud.

Sounds a bit odd but it is highly reliable and works very nicely. I got a whole nunch of stuff running including Unikernels, Alpine Linux, TinyCore Linux and a few even more tiny exotic operating systems.

There's some real challenges to do with the differing ways that the clouds implement networking but I worked all that out with only just enough pain to make me tear out my eyes.

A genuine breakthrough in the narrow realm of reverse mathematics. (The article exagerates that into a breakthrough in general, par for the course for science journalism.)

Here's the actual paper: https://arxiv.org/pdf/1601.00050.pdf

The quantamagazine article puts a lot of emphasis on the youth (34 and 27) of the researchers. I guess the journalist overlooked a more surprising age. Lu "Jiayi" Liu (whom the article briefly mentions for a preliminary result) was I think 20 years old when he made his discovery in 2012 which was a tentative step toward the stronger result in this article. I saw Liu give a talk and it was remarkable. It was in a conference where all the other speakers were very well-established logicians with many decades in the field, and then this Chinese undergrad who was probably the youngest person in the whole building... and all these well-established logicians were humbled by him.

There is no such thing as Infinite outside your heads. This is actually a pattern - a false dichotomy with a pure abstraction produced as an abstract opposite or an abstract result of negation of some other concept or a named entity. Applied Hegelian nonsense if you wish.

Infinity is a pure abstraction, like zero, but ill-defined (zero is an symbol for a concept of an empty slot, absence or nothing, while infinite is mere a negation of finite). Like many other concepts it might be useful, but usability does not imply existence.

> The colorable, divisible infinite sets in RT22 are abstractions that have no analogue in the real world. And yet, Yokoyama and Pateys proof shows that mathematicians are free to use this infinite apparatus to prove statements in finitistic mathematics including the rules of numbers and arithmetic, which arguably underlie all the math that is required in science without fear that the resulting theorems rest upon the logically shaky notion of infinity. Thats because all the finitistic consequences of RT22 are true with or without infinity; they are guaranteed to be provable in some other, purely finitistic way. RT22s infinite structures may make the proof easier to find, explained Slaman, but in the end you didnt need them. You could give a kind of native proof a [finitistic] proof.

I'm not a mathematician, but this sounds a lot like proof by induction VS proof by anything except induction.

however, wouldnt applying bayesian priors ("how often do i see speed limits at intersections?") presumably negate misclassifications?

rather than chase the elusive ~100% accuracy from a single model, why not take a layered, ensemble approach?

Yes, 36 bits or even more I would think.

It seems like they are suggesting that it's feasible to make fiber optics which transmit a picture with extremely low distortion. So a single fiber could carry an optical image instead of a serial bit stream while maintaining nearly perfect clarity.

So you could potentially encode a lot of data (I would think a lot more than 36 bits) into a 2D pattern (like a QR code, essentially) which would enable the transfer of large blocks of data in each frame of visual information.

Of course encoding & decoding the data would incur some overhead...

I don't think PHP's main problem is speed. It's generally used for websites, and a few milliseconds aren't going to make a difference when pages are so bloated by JavaScript libraries to often be 5-10MB.

PHP's problem IMHO is that I wouldn't be able to use it if it wasn't for autocomplete: inconsistent function names, inconsistent parameter order.

The ecosystem is fine, there's Composer, PSR, Laravel. The problem is PHP's legacy.

I wish someone created a PHP class one could use to namespace sane function names and parameter order:

 \PHP\html_entities() \PHP\url_encode()

Honest, sincere, question here:

How is programming in PHP these days? I haven't used the language since 4.x-5.2 or so. I wrote it off completely when Hack and HHVM came out due to the nuances between it and PHP proper (not to say either is bad, it was just another barrier, and set of choices I didn't care to deal with). I typically write Ruby, Elixir, and some JVM based languages these days. Any new features or language changes that make it more pleasant or any good use cases compared to my usual languages? I will add using it anywhere, while a valid use case, isn't something particularly attractive to me.

I fundamentally disagree with this article. Automation hits some places earlier than others, but I think "marketing" isn't as far away as they think. We're starting to develop bots that can make puns, text to speech that sounds human, etc. What happens when bots can pass the Turing Test? When they know everything about the trends you follow, finances you have, products you've bought, shows you watch, places you go, jokes you enjoy? Marketing will start becoming "personalised", and I don't think humans will be behind the controls for long after that.

Humans won't be marketing, they will be marketed. Humans will be a novelty, like a hand-carved chair or a horse-drawn carriage. Probably worse than the human-free product, but worth paying a bit extra for the idea of it.

"but but there is NO job humans can do that a robot cannot do"

this is the gist of the reactions i got to a comment i made on an article on a similar topic here a few days ago.

this article better articulated what i was trying to say there:

But machines are not effective at persuading, at developing advertising campaigns, at branding products or corporations, or at greeting you at the door in a charming manner, as is done so often in restaurants, even if you order on an iPad. Those activities will remain the province of human beings for a long time to come.

people here seem to forget that all this automation is being done to serve us better, the people (i guess you could argue it's really being done to better serve shareholders, but that's another discussion).

we're still weird, unpredictable creatures who eat, sleep, poop, and work in a 4-dimensional world...so there will ALWAYS be a human component to delivering products and services.

even if a good bit of the designing, building, and distribution of these services may be automated.

The bit everybody misses is that people still need something to do with their day.

The problem is the wrong conception of what work actually is. Work is what you do with your day that you find enjoyable and that others consider useful. When that gets paid we call it a job.

And that's it.

Work is leisure you get paid to do. It's a social activity that furthers the cause of the group of humans engaged in it.

If it isn't, then perhaps the system we've chosen to allocate work is broken rather than the concept of work.

Perhaps we need a system that ensures there are always more jobs than people that want them, and that creates work and jobs based upon agreed social value. Which then forces the market sector to compete, which in turn forces market value to align properly with the social value we're after.

You can generalize this to: Someone still has to understand everything in order to make it actually useful for humans. You can build a robot to do work previously done by a human, but you can't make it actually understand when it needs to be working and on what. That would be an exponentially harder problem to make a computer solve.

Making computers want interesting things is perhaps THE problem in artificial intelligence. If you can solve it, you've got AGI. You can hand a machine learning algorithm a very constrained environment and it can work out some basic goals, like making a high score go up.

But increase the complexity of the environment and all of a sudden, the algorithm needs to learn how to simulate it, significantly ramping up the difficulty of what it has to do.

Humans are going to start getting inexorably shifted out of things that humans really shouldn't be doing in the first place, to be replaced by the just-as-difficult task of commanding our new robot slaves. Maybe for a little while it'll be difficult for humans to find purchase in the brave new world, but the limitations of machines to literally read our brains and tell us what we want is going to quickly make themselves known and humans all over the world will take on the role of specifying the behavior of machines that are getting increasingly smarter.

You're going to see the same sort of stratification of haves and have-nots you have now, I see little about the new production modes that's going to change the fundamentals of economics. But everybody is going to have more of it, because making things is going to get much, much easier, even easier than it is now, and it's already really easy.

The robot economy is not a jobs issue. It is a wealth issue.

An entrepreneur's primary function is to create jobs. Every job ever created that wasn't made by the government was a direct or indirect consequence of an entrepreneur. Entrepreneurship is thriving.

A business's primary function is to hire people. Any large business that isn't firing is hiring. And public businesses need to grow to stay in business. 75% of Google's income is from ads. There couldn't be an easier service to automate and robotize than an ad system. Yet, not only are they hiring, but they're looking to spend this money in completely unrelated areas. They're literally starting from "A" and going down the alphabet.

Entrepreneurs and businesses will always look to automate. But they will also always look to hire. Elon Musk is partially responsible for this AI job paranoia, but not only is Tesla not fully robotized they have a shortage of workers and they're hiring like mad [1].

Jobs are about skills, and yes, if you're doing a job that is a candidate for new methods of automation - like driving - your job is in danger. But unless you're only capable of doing one job, all you'll do is find another. You're not a "robot".

And even if humanoids begin to take over more human work, entrepreneurs and businesses will simply hire more and hire them all. We will work alongside our robotic co-workers, and the economy (should) just expand to meet our collective output.

But herein lies the real issue.

Robots will not be owned by robots. They will be owned by people. And if robots are productive, they'll become the new real estate. A robot with a job will be like a house that pays rent.

Bill Gates recently came out with a robot tax video [2]. But taxes are not enough to equalize the wealth gap. It hasn't worked for humans, and it won't work for bots.

Not only money, but ownership needs to be redistributed. Unfortunately, we have yet to find a solution for this old problem either.

So what if you lost your job if you own two apartments that bring in a middle class wage? Replace apartments with robots.

The Robot Economy is not about jobs. It's about wealth.

I was under the impression that comments on news sites were mostly to divert the readership from directly contacting the author or the company through channels that are listened to; merely a solution to keep the wacko segment of the readership occupied and satiated. At least in practice, this is how it appears to function; they're almost exclusively 3rd party plugins and nobody that works for the news organizaion seems to ever engage with them.

I've often thought that those who make decisions for society should be required to pass a test to show they understand all sides of an issue. It is absurd to me that politicians are currently allowed to make the wide variety of decisions that they make. I don't think anybody really wants to vote for them to do that. (There was an old episode of Star Trek that had officer candidates use the holodeck to be exposed to a wide variety of situations and outcomes. I would think that whatever we could do to emulate that should be a requirement for making associated decisions.)

This looks like a brilliant tool! It's always annoyed me how slow copying stuff over the network using a GUI is -- especially folders with many files.

For example copying a 300MB folder from one Mac to another over Wifi took 10 minutes (using the Finder). Then I tried using rsync from the command line, and it took just 15 seconds.

I don't often use rsync, so I always have to look up the required flags every time I use it. A friendly GUI is greatly appreciated!

Beware, though. It's true that the war on drugs seems to do much more harm than the products they try to prevent people from consuming, but I would worry a bit about a world where big pharmaceutical could suddenly research recreational drugs as business opportunities.

Medicine is only for sick people. Recreational drugs would potentially be for everyone. Plus, they can be made extremely addictive. It's the perfect commercial product.

New drugs already exists that are more addictive and powerful than old ones. Like Fentanyl, for instance[1]. Who knows what research labs would come up with if they threw lots of money and brain power into it?

A global legalization of drugs would be quite a Pandora's box. I'll quote Noah Harari and say it would start what he calls "the chemical pursuit of happiness" [2].

In the end, the risk is that we end up like the woman with an orgasm button[3], or turn us into some kind of vegetative state, as described in "the metamorphosis of Prime intellect"[4].

The war on drugs policy is a disaster.

As someone who enjoys doing drugs I have put though into the stigmatization legality and health effects of drugs.

Much like healthcare this is an extremely complex subject.

Decriminalization:

Pros: helps treat addiction as a public health issue. Keeps people out of the prison industrial complex. Takes the taboo elements out of it for the youth.

Cons: supports the drug trafficking systems that kill people. Strips tax revenue from governments and money from 9companies who can help treat addiction. No quality control of drugs - look at tweekers and junkies who can't afford quality gear. Spread of infectious diseases.

Legalization:Pros: substances can be produced by companies who can compete to make good quality drugs. Generates tax revenue and stimulates the economy. Puts a wrench in the cog of the drug trafficking systems - less babies filled with dope and dead drug mules.

Cons: companies exploit addicts. Drugs get marketed to the wrong people. Drug revenues go to support more corrupt politicians. Drug addiction becomes normalized.

It also raises other questions such as what are the goals of our greater society? Living in a rigid corporate, industrialized society leaves little time for many people to have recreation time. Being strung out or twisted on meth can make it hard to keep up with the rigors of life.

I also don't want the construction crew down the street drunk or high on heroin working the tower crane... downers impare your motor skills. Stimulants go after your cognitive and social abilities.

Tough topic.

I don't think we are ever going to be able to move towards a perfectly-reasonable public stance towards intoxicants. My personal problem with marijuana is that I just don't want to smell the shit everywhere.

Your human right to ingest whatever substance you want is going to inevitably conflict with my right to choose whether I want to ingest it too or not. We've gone in one policy direction with marijuana, and another entirely with tobacco. Once you get to legalization, you're inevitably thrust back towards getting it the heck back out of the public sphere.

Tobacco seems to offer the perfect opportunity to examine the intersection of human rights way of looking at it with "plain ole'" regulation for greater social harmony. Tobacco, like it or not, is a mind-altering drug that people rely on for all sorts of really personal reasons. Our recent push to banish it is pure and simple classism.

But the people decrying the war on drugs also seem to often nurture a quiet bigotry against smokers. Smoking is legal, for now at least. But eventually you won't be able to light up without running afoul of some regulation, God forbid they start actually enforcing the now-common 50 foot rule from the entrance of businesses.

So yeah, maybe the focus on tax revenue is probably the best one. I like human rights as much as the next guy. But I'm gonna turn into a raving classist asshole the second my neighbor forces me to smell his damn weed through the shared wall. (yes it's happened) I'm already quietly cheering the slow banishment of tobacco, cognitive liberty be damned.

Sure, cannabis and tobacco are both smoked, and not all drugs are. But are we really prepared as a society for a world in which drug use is truly legal? Are people really forgetting that these things are well and truly dangerous? Cocaine makes a real mess out of people.

What about synthetic drugs? I don't think you're ever going to be able to convince a reasonable person that those things should be legal. So there you go, War on Drugs part 2.

To sum up, legalization isn't really a viable public option. It's a fantasy.

Here is a somewhat similar design, from 2016. It uses gimballed rotors at either end instead of modulating the angular velocity within a rotation cycle. Seems more sensible to me to do it that way, and it shows fully controlled flight (even flips it over at one point) instead of the little hop in TFA.

What is not proven for me is that this is more cost effective than the quadcopter. The unbalanced rotors look like they will need expensive bearings. The complex speed control looks like it is going to be very expensive by the time they have tackled the efficiency issues. This is vs using just two more identical motors. This brings economies of scale, plus you can use smaller motors. The efficiency issue alone may mean a quadcopter needs less battery capacity, allowing a lighter payload. Always interested in a novel design, but still lots to prove

Since the author is reading, a few small typos, followed by one slightly more substantial comment: 'simgoid' should be 'sigmoid' (S-shaped); `x y = log(x) + log(y)` should be `log(x y) = log(x) + log(y)`;'guarentee' should be 'guarantee'; 'recipricol' should be 'reciprocal'.

I would like to see some mention of the fact that the division by the gradient is a meaningless, purely formal motivation for the correct step (inverting the Hessian) that follows.

The author has far too little mathematical understanding to be teaching anybody (thats my impression at least). If you dont understand Newtons method before reading this, you wont understand it afterwards. A method for finding the roots of a polynomial. Why polynomials? Does it work, always? Is it fast? Why would following the tangent repeatedly be a good idea? We take the inverse instead of the reciprocal because its a matrix. Not impressed.

There is an important distinction between someone who doesn't misbehave for fear of being watched, and someone who wishes to be watched in fear of the perception of misbehavior.

There is no substitute for someone who's intent is to try and get away with things, and someone who's intent is to serve a cause, be of service, and not get away with anything.

So really, we should build a system where the intent of transparency is paramount, not just transparency itself.

Two things immediately come to mind.

1. Super-incentivize snitching. Reward whistle-blowers to the point where it becomes an easy decision. Not only monetary, but with honor and with medals. Make it the new "right thing to do" in public service. Fight corruption. Easy sell.

2. Super-disincentivize ulterior motives and their actions. Treat crimes by officers as far more severe and malicious than of non-officers. And they are. So if a police officer murders a civilian, punishment should be 10x or 100x. Same with stealing a slice of pizza or ignoring a stop sign.

The point isn't that we should punish officers more. The point is we should all raise them to higher standards, and the officers themselves should willingly accept that higher burden of responsibility.

It should be their responsibility to not profile or discriminate based on appearances of anyone or their car. It should be their responsibility to preserve life at all costs, even at a higher risk to themselves.

And this will deter crookedness and incompetence. If an officer cannot do their job, they shouldn't. And if an officer thinks they can get away with anything, they shouldn't. Being a cop or even buying a cop like in the movies should not pose any criminal opportunities.
