I'm sorry, what do you mean by this comment? If they use MIT licensed software there's no obligation for them to contribute back anything, not that it's good or bad, but it's the terms of the license.

Also there's no way to know if they have contributed or not, and even if there's no direct contribution (pull reqs) we can't know if they haven't reported bugs or supported employees that wanted to collaborate to the projects on their free time.
I had similar thinking about how alien that would be in a previous discussion around service culture in the US vs. Germany.

In the US, it is expected that employees in service businesses (think coffee shops, grocery stores, etc.) put on a smiling face and pretend to love their jobs. In Germany, I was told that is unheard of because it is thought of as inhumane to force someone to pretend they love their job like that. So as a result you get some less-than-enthusiastic responses from those employees.

I encountered this a bit in a coffee shop in Vienna and it was stark to say the least.
> In general I find that the speakers from Asia have to try harder to be understood because of the reduced shared vocabulary and different phonetics. It seems much easier for a speaker of Spanish or Italian.

That's because esperanto is pretty much latin + german + russian. That's the roots of the esperanto.

Esperanto was a silly attempt to "unify" europe via a single language.

The article was rather silly. But I guess it was written by esperanto fanatic who wants to spread esperanto. It'll never happen - lest of all in asia, but the best of luck to him.

I worked in edtech for 3 years (left job last November). Spoke to many others at events (ISTE, etc). The main struggle was how to move content from one platform to another. Every product had its own proprietary format and most didnt have a way to export. I worked on a solution with a publisher but abandoned the idea the moment they mentioned not wanting to do an open format.

I also had some issues with student data being different across all SIS. Had to implement my own solution to normalize the data and serve it to my own production systems (eventually was sold to clients). This was never truly solved because the moment I left the company focused on another product (it wasnt a "data" company like Clever).

It's sort of silly but it's sort of not. The evidence suggests that a few really big hits doesn't do it, it's repeated medium sized head traumas that does. (ie: it happens to line men more frequently out of footballers) Quantifying the size of that head trauma is really key. Does it have to be a "hit?" I mean repeatedly hitting mogul runs put shock on your whole body, you may not hit your head but you're absorbing that up and down shock and moving side to side fairly abruptly; more so that you do just running around and your brain absolutely experiences some amount of that. Age might have a factor too, age when this trauma or shock happen.

I ski and snowboard and I'm not planning on stopping, I think the benefits outweigh the risks. I'd say that about most sports but I'm not about to let either of my kids play football or box.

We need to study this stuff a lot more.

I had a response all typed up, but I wiped it, because I'm being unproductive by trying to argue. I should be trying to understand.

My viewpoint is that the only reason to oppose gay marriage is because you believe that gay relationships are inferior to straight relationships. Can you please explain to me a reason to oppose gay marriage other than that? You listed a few earlier:

> People who didn't like the Foucauldian agenda behind the whole thing, or the judicial overreach, or mayors like Newsom overreaching, supported Prop 8.

I don't know what "Foucauldian agenda" means. Sorry.

"Judicial/Newsom overreach" don't make sense to me in the context of a public referendum. These people voted against something they wanted just to prove a point about something else(?); and then what, they were going to vote in favor of it again sometime in the future? Okay, but that's pretty baffling behavior.

I just have a hard time believing anyone in support of gay rights would choose to vote against gay rights and support anti-gay organizations. Maybe you can explain this more for me.

Hi Manishearth! I know you work at Mozilla.

If you see this: Do you have anything to share WRT the possibility of having extensions like tree-style-tabs in future versions of FF?

This is probably the one thing that leaves most Chrome users awe-struck and also is really really really useful to many of us.
You can create a "to read later" folder in your bookmarks, then right click the tab bar in each window and select "Bookmark All Tabs". That's fairly close to what you're describing, and also works with Firefox Sync (though in my experience it's best to keep the number of bookmarks below 5000 for Sync to work well).
Depends on what the definition of production is. Sourcing all the components for 10,000 units and building a reasonable BOM that business will accept is a typical type of production I see... not something that you can do with a Pi.

This Is Water: Some Thoughts, Delivered on a Significant Occasion, about Living a Compassionate Life
OT but what I found most astonishing about this article it's how the author takes for granted that kids would be involved in drugs and games and other vices.

Honestly, what kind of society is this? I would be scared to raise kids in a place where these things were common.
> 20 consecutive headers in 10 minutes is astronomically rare occurrence in soccer

For what it's worth, this is a completely reasonable number. In a game situation, sure, headers aren't that common. But during my youth soccer days, we practiced at least twice as often as we played and practice with headers was quite common. Ironically, they were trying to teach us the proper technique so that we wouldn't hurt ourselves. I can easily imagine practice sessions in which we headed the ball at least 3 times as often as that 20 per 10 min number.

> Marketing: The worst. I’m bad at it and it just does not interest me.

This resonates with me, and I am sure a whole lot of other engineers working on side projects out here.

What's the solution? How do you find a "Marketing" person on a side-hustle budget? Without any network.

Like OP, I know my side-projects need to be marketed, but I also don't enjoy cold emailing or cold-calling and would really leave it to an expert in that domain, as long as I can pay him/her by output and not on a full-time salary or a contractor rate...
I don't think this comparison stands up, at least not for most reasonable interpretations of "aggressive skiing". It might not involve any crashes at all.

I think there's a fair distinction to be drawn between sports that might cause head trauma if you make a mistake, and sports in which head trauma is practically the defining characteristic (see also: boxing). I am three weeks away from having a son, and while I've got some years, I'll eventually have to make some decisions about what activities I want to encourage and discourage. It at least seems possible to learn to ski without repeatedly bashing your head. Not so for football.
There's a difference between at least attempting to be unbiased, and knowingly exaggerating.
If people use tabs as bookmarks, perhaps it is because something is wrong with bookmarks.
Or the fact that an overwhelming majority of football players don't ever collect a paycheck. It isn't like all of these NFL players just started receiving brain damage once they reached the NFL at the age of 22. They probably started playing football in their early teens. Odds are no one else on that player's middle or high school teams and only a hand full of people on their college team made the NFL. Yet they were all subject to the same type of head trauma.

I would like to think that no, my spending tends to be largely on things that do not tend to be advertised (craft beer and bills, mainly). But no doubt you are right. Still, if its so passive that I can barely detect it happening, all power to them.
Yes, but that's why I have a backup; if recovery fails, I'll just restore my Firefox config files. I've done it before.

I also fail to see how preemptively closing my tabs so that they don't accidentally get lost helps me any.
That's the modern risk, right? Taking into account all the things those professions do to mitigate the risk? If you've seen someone remove asbestos in the past 20 years, it's obviously not as if they're just wearing jeans and a t-shirt and hauling armloads of the stuff.
But Trump is a coastal, city elite who thinks their religion is hogwash, their values are garbage, and that they're ignorant. OK, he probably doesn't have a problem with racism or whiteness, but it seems like the rest are close enough. And he absolutely is part of the same system. To believe differently you'd have to be, well, an idiot.
Wouldn't be sure about that. Plenty of companies will catch up quickly especially ones like Palantir.
I feel like it boils down to options a bit.

If I don't take the opportunity to work in Australian mines, will I have a reasonable opportunity to find work and provide a comfortable living for my family?

If that answer would change whether or not I'd work in a mine, I'd consider that the work may be exploitative of a regional work shortage. At that point someone might feel as though sacrificing their health is their only option, and an informed decision is much harder to make.

Like many ethical questions, it warrants discussion even though there may not be a "right" answer either way.
Yes on both. I work in tech that services the trucking industry. Getting drivers, (and dispatchers, actually), to truly trust a computer is difficult. They use a lot of apps, but trucking's got a strong culture of self-reliance, and people working in trucking probably care more about single points-of-failure than DevOps do, relying on Convoy would be a pretty big single point of failure, so they'll have to prove themselves worthy of the trust.

However, 82 million should get them there. That's a ton of money to build a business with no capital costs. The big risk for them is the incumbents deciding to move quickly - most of them have the cash, so if they realize their business model is threatened by Convoy, they'll move quickly, and be supported by their existing cash flow.
Sports, as a fun hobby is one thing, but the article discusses the NFL; big business in and for the USA. Rather than say hey, this is hurting people, maybe we could change the rules some, the NFL is doubling down and is the one pushing the "all sports are dangerous" emotional narrative to mother's of children, in order to get them to play, all so they can pad their bottom line.

I agree partly, see my answer below.

However lamenting about this does not help anyone. Everyone has his own incentives.
I don't use most Google services, and when I do they're sandboxed, but Google cookies are omnipresent. I have no faith that my incognito efforts are all that incognito.
That was Brooks' reaction against the logic-based AI of the 1980s. Around 1990 I went to a talk where Brooks was plugging the Cog project he was starting.[1] Brooks had some success with purely reactive insect-level AI, and was trying to make the big jump to human-level AI. I asked him, why not try for mouse-level AI. That might be within reach. He said "Because I don't want to go down in history as the man who developed the world's greatest robot mouse."

This is a classic problem with AI researchers. Somebody gets a good result, and then they start thinking strong human-level AI is right around the corner. AI went through this with search, planning, the General Problem Solver, perceptrons, the first generation of neural networks, and expert systems. Then came the "AI winter", late 1980s to early 2000s, when almost all the AI startups went bust. We're seeing some of it again in the machine learning / deep neural net era.

This time looks more promising, partly because we can throw more compute power at the problem. Many of the ideas in machine learning and neural nets are old, and are so inefficient that they were hopeless until people could beat on them with racks of GPUs.

The big difference this time is that AI is profitable. The field used to be tiny - maybe 20-30 people at MIT, Stanford, and CMU, with a few small groups elsewhere. Now there are hundreds of thousands of researchers, and profitable applications.

(I went through Stanford just as the expert system boom was collapsing and the "AI winter" was beginning. I met most of the big names from the logic-based AI era. It was kind of sad.)

Don't get me wrong. I just found it weird as I thought if I personally wanted to quit tech I'd want to stop reading HN as well.
have you attempted to apply any formal methods (coq, isabelle, tla, whatever) to your code? or will you be content with mere auditing?

I can't stress how important that is. We have about 1.5k tests in our Phoenix app and they almost all hit the database - they run in 30 seconds. I compare this to a Rails app where 1k tests run 8 minutes. Having a fast test suite makes development so much easier and makes you rely more on tests.
Although what seems to be replacing malls, at least where I am, aren't revitalized public shopping areas but rather "lifestyle centers" which are areas that look like traditional downtown shopping areas with blocks of connected stores along streets, but which are as privately owned as the enclosed malls were.
Yes, I have. I would say it's pretty easy. Had it not been for rustler I wouldn't have touched NIFs since I'm not a C programmer. Also, rustler supplies elegant building blocks, which makes it a straightforward experience.

I've had a few issues with the version of rustler published on hex.pm not working with Erlang/OTP 20, and I've tried using the master repo as a dependency in my `mix.exs`, but that didn't work since rustler repo has an unusual directory structure which fails to compile. And then lo and behold, I've discovered how amazing the `mix` tool is and via `mix help deps` I've learned that you can actually check out a specific directory (via `sparse` option) from a remote repo as your dependency.

Now my dependency listed in `mix.exs` looks like this:

{:rustler, ">= 0.0.0", git: "https://github.com/hansihe/rustler.git",
tag: "0.15.1", sparse: "rustler_mix"}

... and problem solved. I guess peeking at rustler's tests helped me a lot.

All in all, the entire Elixir ecosystem is really elegant. Such a joy to write code now!

It makes complete sense too as FB makes bigger plays at pre/mid-roll ads in videos. Seems like this could be an effort to limit their liability from serving ads on top of work with copyright issues and then profiting from it (or paying out a revshare to the uploader who may not be the rights holder).

No, I just think it's paradoxical to free your mind of fixation only to fixate on something else (relentlessly helping others).

I don't think being happy, or contributing to society requires a fixation on giving - or for it to be uncomfortable. Bill Gates seems to be a pretty generous dude, but I don't think he makes being Jesus-like his identity. So in a certain sense, I think working smarter not harder is a healthier and more sustainable mentality.
I have to confess its not turing complete (yet) so technically I shouldn't go around calling it a programming language.

The project is still in its early stages, so expect some hiccups. All feedback is greatly appreciated :)
When Chrome crashes, or when I reboot my Mac, it reopens the previously existing tabs.
One of the safest sports I've seen is oddly flag football. Especially for youth. There's typically no blocking allowed at the youth level, and obviously no tackling.

Of the youth sports I'm involved with flag football and baseball are the two safest (especially if you're not a pitcher). Then basketball sits in the middle as pretty safe. The main worry in basketball is running into someone going for the ball. I'd put soccer and tackle football as the most dangerous (tackle football being more dangerous). If they eliminate heading out of youth soccer, it would move it into the basketball level of safety.

I'm not sure there is any way to change tackle football to make it reasonably safe for kids.
I completely agree. It should be way easier to "braindump" a window full of tabs into a folder of bookmarks. There are browser extensions for this.

Alternatively, browsers could start treating window + tab lists as less ephemeral, and make it easy to restore window + tab combinations at any time, regardless of whether the browser thinks it crashed recently.
Jack Ganssle wrote a much more thorough article on the same topic here, if anyone is interested in the EE nitty gritty.

I think that they're actually talking right at each other, but Zuckerberg is thinking of the possibilities, while Musk is thinking of the implementations.

"AI is the future" really means that Zuckerberg sees the massive potential of automation, and how it's going to change the face of the world.

"We should be worried about AI" really means that Musk has had to think long and hard about the fact that the software written by Tesla is navigating living human beings around obstacles at high speeds.

This isn't about some accidental super intelligence that becomes self-aware and murders all humans, it's about the consequences of applying today's standards of "let's ship this code" to technology that we're expected to entrust with our lives.

This is two things, combined: "AI" means that code will have more complex emergent behavior that's harder to debug than current code, which is already nearly impossible to completely debug. "AI" also means that this code will run very complex systems that often have powerful hardware components, unfortunately including weapons.

To put it another way: Both men agree that the code of the near future is going to make a massive leap in effectiveness and real-world applications. But Musk has to grapple with being held morally accountable for that code, while the only thing Zuckerberg's ever had to care about is performance. Say "AI" to Mark Zuckerberg and he sees all of the money in smarter data mining and fun home appliances. Say "AI" to Elon Musk and he has nightmares of deploying a wireless update that causes Teslas to confuse people wearing green clothing with green traffic lights.
So you would like to control the information people receive and push them into different directions based on whether the "facts" are correct or not according to some set of rules? I think we need less reliance on tech and more common sense and independence of our own free thought. We should do our own research and investigative work before we believe the clickbait headline of the article we did not read.

You're right, but a) you have comp efficiency issues with MCMC, and b) just empirically MCMC models don't work as well as gradient descent + NN for many tasks.
It usually does this.

Sometimes it fails, or Chrome crashes a second time after relaunching, but before you were able to restore the tabs, causing the next restore to open a blank window instead of your tabs from two crashes ago. This happens more often than I'm comfortable with.

It would be really nice if browsers kept a history of your last N window + tab sets and allowed you to restore them whenever you wanted, rather than only the last one, and only after it thinks it crashed. Because when it gets this wrong, you usually have no recourse.

> deterred from defaulting on their loans insofar as their future creditworthiness on the platform will be marred

Oooh, scary :-) You're not even threatening to half-assedly try to involve authorities if someone just runs with the money?

I think this is a very interesting engineering feat, but it does seem to suffer from the basic problem that there is no real connection between the real world and this fantasy world called "the blockchain".

Also, a small comment on the README:

> submitting to the contract any subset of the investors' bids whose total cash amount is equal to the desired principal

If you really mean "equal" here, you are looking at the NP-complete subset sum problem in general. Also, there might just not be solutions at all. Maybe you don't actually mean "equal", it should become more practical if you allowed some deviations from the borrower's initially specified amount.

I have to say, out of all the things the DoD pays for with its massive budget, things like paying the NFL to fly F16s over stadiums, or TV ads, or sponsoring college courses are what really grinds my gears.
