Their plan for profitability so far has been "invent a ground breaking technology that will change the world before we run out of money in a couple years". That sounds more like delusions of grandeur than unstoppable juggernaut. Hopefully that changes under Khosrowshahi.

Uber may well yet become an unstoppable juggernaut, but they could just as easily flame in spectacular fashion.

And if you think GDPR is a toothless joke, let's take a look at the defined fine stucture.

It is pretty simple, only 3 levels (strikes for the fellow Americans):

Strike 1 - Stern warning letter

Strike 2 - 2% of your TOTAL GLOBAL REVENUE

Strike 3 - 4% of your TOTAL GLOBAL REVENUE (or 20mil EUR, whichever is higher)

And now you know why GDPR is a board level topic. Keep in mind that the EU/US Safe Harbor agreement got axed due to a lawsuit of a single student from Vienna against Facebook. So all you need is a single pissed off German customer you ignored when asking for their data report card and you're fucked.

For startups - GDPR is like Y2K at the time, a GOLDMINE. So much opportunity to sell solutions, from real to snake oil. GDPR compliance is already and will continue to trigger a massive wave of investment.

Enjoy :)

Fun fact, the Mono Linker project started 10 years ago during the second edition of the Google Summer of Code!

It was originally used to reshape the entire Mono class library into a subset to expose the Silverlight class library API surface for Moonlight.

It was then used to link iOS and Android applications in MonoTouch and Mono for Android, and Xamarin continued to use and improve it.

The Mono Linker has an open architecture making it reasonably easy to customize how it processes code , and detect patterns specific to each platform to link them away. Xamarin added linker steps to do more than tree-shaking, and remove dead code inside methods. For instance:

if (TargetPlatform.Architecture == Architecture.X64) {
// ..
}

The entire if body can be removed if the linker knows that TargetPlatform.Architecture will not be X64.

And now, it's the base for the .NET Core linker. Quite a journey!
You can still get close to that today, even outside of tech. Tradespeople make plenty of dough.

The problem though is survivorship bias: plenty of people in the '50s and '60s were poor, or didn't buy their own house, or etc... and likewise plenty of "kids today" are doing well.

I would imagine that such a device would be difficult to build so that it works correctly the majority of times it is used. Even if the "reverse printing" idea could be done (I like the idea, btw), it would have to be extremely exact to line up the "pixels" of the images with the individual lenses. Perhaps a print-head with some kind of camera on it to see where it is printing as the head passes over the lens could be done?

Recall that these kinds of "motion picture cards" have been around for decades; at least 40 or 50 years, maybe longer. If such a camera (or even a home-based process) could have been built for consumer use, it probably would have been sold. The fact that it wasn't, and the fact that even during all these years there haven't been many manufacturers of such images, should give you an idea of how difficult registration of the image stripes with the lens can be. A purely mechanical process (printing the image onto some kind of paper, then laminating the lens over the top) probably can't be easily (or cheaply) done - otherwise it likely would have been.

That's just my take on things, of course; maybe I'm completely wrong, or there's some method or such I am missing that could make the system easier to build today? I do think the idea of "reverse printing" might be a step toward it. I can't think of how you'd build such a thing to be hand-held, but I can imagine a desktop-sized machine being potentially possible (again, using some kind of close-imaging camera or some other method to register the printing of the images with the individual lenses on the plastic).

If reducing violent crime is the goal, there are of course many ways you can accomplish that. We should also weigh it against other goals like freedom from excessive tax rates.

But as far as solving violent crime through egalitarianism, focusing on executive pay (which is a tiny fraction of the population) seems misguided. Its too small a number of people to have a noticeable affect on violent crime.

This seems to mostly solve jealousy more than anything else.

Except that there are many examples now of human scale 4, 6, and 8 rotor craft. So perhaps the litmus test is 'efficient enough'. And the article did point out the need for improved batteries.

From the standpoint of the concurrency scheme I'm proposing, it's OK to move the cell in the GC. Then it becomes a standard GC moving problem.

In JSC we don't move cells for other reasons, and the point of saying that they don't move is that the object model itself does not require the cell to ever move.

It's slower, but not much slower. The baud rate can be set up to 4,000,000, where a megabyte would transfer in 2 seconds. These "gifs" don't seem to be more than 10 seconds long, so they should be less than 1 MB, judging from random Giphy mp4s.

I can't find the citation right now, but I remember reading that a European country required all gas stations to report their price to a government database, so that consumers could easily price compare.

It caused prices to go up, since now the gas station can easily see he doesn't really need to compete much, so they just barely went lower then their neighbor. After a few cycles of that prices ended up higher.
Strike 3 - 4% of your TOTAL GLOBAL REVENUE (or 20mil EUR, whichever is higher)

Why would they impose a 20M limit and not stick to 4% revenue irregardless of it...

edit: I'm not sure that the down voting is about.. it's still a limit, a limit that means a company turning over 0-500M will pay up to a 20M fine.. not so bad the closer you get to 500M but not so great if you're a small company, especially so as the regulation is so open to the "law of unintended consequences" right now and only larger companies will have the funds / man power to navigate it.

It's weird in a larger historical sense, but in a contemporary sense not so much. The US has moved radically rightward since the 1980s, and that only got kicked into higher gear since 9/11/2001 once 'patriotism' or 'security' could be tapped any time to shut down critics. It's not just a difference of opinion when you can claim it's some sort of existential threat.

From my perspective, it looks like we're in some respects in a similar situation as we were 100 years ago. Huge advances in technology have made individual workers radically more productive. Assembly-line manufacturing then, computers and Internet now. And just like back then, while everyone predicted a future of shorter work weeks and less work, employers drive employees harder, and pay them less, while society says "the machines do the real work." There is one big difference though. Back then it got solved by the New Deal stepping forward and forcing companies to essentially give their workers a 600% raise basically overnight. Going from employing a whole family, children included, 16 hours a day 6 days a week and paying them barely enough to feed themselves... to 1 person working only 40 hours a week and being paid enough that the entire family could be comfortable on just that one income. Suggesting such a socialist solution back then would elicit discussion. Nothing of the sort can be discussed today. One whisper of the word 'socialism' is followed by 'communism' and all discussion is aggressively ended.

Show HN: An API to provision custom hostnames with SSL
We launched an API for custom hostnames today. A simple HTTP post with a hostname gets a temp hostname with CNAME/a record instructions, as soon as DNS is setup we issue SSL and start accepting traffic for that hostname. It's the quickest way we know of to provision custom hostnames: https://fly.io/mix/custom-hostnames/

When we started building Fly, we figured it was too late to "make SSL easy and the customers will come". Lets Encrypt changed the world, and we knew many companies rolling their own SSL support with nginx, Traefik, etc, etc. It seemed like a solved problem.

It turns out that SSL is still a pain, particularly companies with lots of hostnames pointed at them ... anyone hosting apps/content on behalf of their own customers. Distributing certificates, keeping them renewed, and — most of all‚ making https fast is still hard. Devs can solve the basic problem in a week or so with a proxy, but then it sits, and no one feels very comfy with untouched infrastructure. And it's usually something distracting devs from more important work that's core to their own customers.

So this is our way of solving that problem. We can handle any number of hostnames for applications, devs can spend more timeon what makes their apps special. It's a relatively "simple" use of what we've built, but solves a really fundamental problem for a many companies. It's the most fun thing we've discovered this year.

So, if you're building an app, and serve stuff on behalf of your users, we can make your life easier:

Bernie Sanders and the Nordic countries are Social Democrats. https://en.wikipedia.org/wiki/Social_democracy

Social democracy is a political, social and economic ideology that supports
economic and social interventions to promote social justice within the
framework of a capitalist economy, as well as a policy regime involving a
commitment to representative democracy, measures for income redistribution,
and regulation of the economy in the general interest and welfare state
provisions.

The "democracy everywhere" which you describe sounds like Democratic Socialism, which is a bit further to the left. https://en.wikipedia.org/wiki/Democratic_socialism

Democratic socialism is a political ideology that advocates political
democracy alongside social ownership of the means of production, often with
an emphasis on democratic management of enterprises within a socialist
economic system. Democratic socialists see capitalism as inherently
incompatible with the democratic values of liberty, equality and solidarity;
and believe that the issues inherent to capitalism can only be solved by
superseding private ownership with some form of social ownership [in the
form of democracy].

Relevant: "Why haven't quadcopters been scaled up yet?"[1]

The gist is, scaling up multi-rotor systems isn't as simple as making things bigger - the size adds many issues that the small models don't face (models having nearly impossible performance characteristics compared to full scale versions). Also, there's safety issues regarding controlling such as system when one or more rotors/motors fail.

It's not to say it cannot be done, because obviously it can. It's a question of "why?", when there's clearly better, more simple and efficient ways to get around.

Also, battery power density (and weight) has a long way to go before it will match Kerosene, or even regular AvGas - "Could an electric engine provide the same performance as jet engines on current aircraft?"[2].

Learning how to draw pixel art in Adobe Photoshop is a fun process as it challenges the artist to focus on a minimalistic way of thinking. It can be quite the process, but the rewards are worth it!

In this tutorial we will be using Adobe Photoshop CS6. There are other programs (paid and free) that have similar options. This tutorial works with many of them. Photoshop has a lot of readily available features for pixel art, and utilizing these features makes the creation process highly suitable for the art process.

Thank you for sharing your experience and practical perspective. That was really insightful - especially the part about how your successful projects start out as rough sketches, quicker to start the better; then mature over time, migrating to other types of databases as needed.

Such a pragmatic approach, to use the right tool for the job, while keeping the advantage of having a range of tools at hand.
Well played! (Though I would argue that the parent is still technically correct about multirotors / quadcopters being very inefficient compared to other flight methods)

That said, I am really curious at actual lifetime costs of a system like this, and if it makes up for lack of efficiency by being simpler mechanically (leading to lighter weight, less maintenance costs, etc.) I think thats going to be the big thing that determines if this is a viable commuting option vs. rich person's toy.
ah thanks for letting me know! I was just working off images of the camera I found online, I guess I could have actually used it to control exposure on the piCam

One purpose of _source is to make the namedtuple self-documenting -- that has been a considerable benefit over the years and has resulted in many fewer questions and issues than we usually get about our other tools.

Another purpose of _source is so that you can write it out to a module. This lets you pre-compute the named tuple for speed and it makes it possible to easily Cythonize it or to customize it (in particular, people like to take out the error checking).

Since the namedtuple() factory function was already creating the source string as part of its operation, just storing it and exposing the attribute had nearly zero additional cost.

That said, don't worry about it, next week I plan to make this a lazily generated attribute so you all can sleep soundly at night :-)
