I'm non-plussed. Their "Hello World" example in C is essentially unparseable for anyone who doesn't already know what's going on. Anyone care to explain it? I don't know how much of this example is written in js and how much in C, how much is boilerplate or anything. It's awful.
Ask HN: Has open-sourcing every killed a company?
A common fear I hear from people who don't want to open-source their projects is that a competitor might steal their code. I've personally never heard of this happening, but I'd be interested to hear any stories about it.
That's not nihilism, but a correct free market response to over-investment in a particular asset type.

The fact that this didn't happen is due to regulation and other market distortions.
> Just because that memory is reserved at boot doesn't mean it suddenly has no lifecycle of any kind.

Yes it does. The "lifecycle" is: allocate at boot, machine halts.

All of the memory you describe for other purposes is allocated at user level and booked to processes. This is how you make a kernel immune to DoS.

> Nobody said anything about C++ throw/catch exceptions.

That's the only meaningful difference in error handling between C and C++. Since you mentioned error handling as a reason to choose C++, what else could you possibly mean?

> If you want to avoid C++ that's great, but to argue for C over it is insanity rooted in nostalgia.

Sure, you keep believing that. It's clear you're not familiar with microkernel design. The advantages C++ has for application-level programming are useless in this domain.
The car cannot drive itself

It seems like Tesla is careful not to dispel the illusion it can. Like how alcohol does not get you women- but all the adverts deftly imply it can, without actually saying it can.
I don't get it. Doesn't autopilot mean that the car is steering itself? "Perfect" or not, if the car is steering itself, what is the point of having your hands on the wheel? I get the point about being alert, and needing to take over if you see an issue, but I would fear that I'd be overcompensating autopilot by having my hands on the wheel while cruising along.

Can somebody explain?

Software Engineers are the easiest to outsource. A manufacturing company would have a hard time convincing people from the other side of the country to move to work. A company can easily get a software developer who is willing to work remotely.
The assumption there is a feasible application of something in a location to remediate a world wide problem is attractive but I think built on faulty logic. To try an analogy, gluing a broken cup back together doesn't make it never have broken.

Yes, we probably can re-salinate a flow to attempt to alter its dynamics. We'd also have altered its salinity profile in ways which have repercussions on e.g. cod fisheries, or krill, or other things. Thats the problem with complex biological systems with lots of interrelated parts: they don't reverse with simple tweaks because once you change one part, you change lots of parts in unexpected ways.

(I did once study this stuff back in the 80s and was very bad at it, but what I recall of even two-actor predator-prey relationships is that they are remarkably complex, cyclical, and do not just return to the same stable place if you alter them trivially. I believe this is probably even more true for physical systems like weather and climate)
Minecraft's Far Lands aren't actually related to floating point precision, although movement near the Far Lands is affected.

My understanding of what causes the Far Lands isn't that great, but I think it's caused by one of six or eight shorts overflowing in the generation algorithm.

If you’re only realizing now that climate change will end civilization, you haven’t been paying attention.
I had similar thoughts some time ago but came to a very different conclusion: anything the shell can do a programming language could do just as well, given the right interface. The fact that languages don't make it easy to spawn subprocesses safely doesn't mean that they couldn't do so. The right solution is making it both convenient and safe to do shell-like things from within a real programming language. So I made sure that Julia does this right:

> Supposedly qualified, intelligent engineers who were no doubt aware of these points

Are they aware of them? That's not so clear. There's a lot of literature in microkernel design. Lots of things have been tried which sound good but haven't worked out, and some things didn't work out well before would work well now. As usual, security also rarely gets the attention it deserves and it's doubly important at the kernel level.
>There's so much money involved here and so much initial traction that it is indeed reasonable to think that tech can surpass a "normal" driver.

I don't think it is reasonable at all to reach that conclusion based on the money involved...You just can't force progress/breakthrough just by throwing money at all problem..

>I'm also biased against human drivers, plenty of whom should not be behind the wheel.

So I think it would be quite trivial to drastically increase the punishment of dangerous practices if caught. I mean, suspend license or ban for life if you are caught texting while driving or drunk driving.

LOC is not a good way to measure the "bloatness" of a software. There is a significant amount of device driver code in linux kernel. With the number of devices exponentially increasing, it is inevitable, but it does not make the kernel more complex.

A truck is not more complex than a car. A truck is bigger because it is designed to carry more load.

Well that's a shame! Unless we're missing something in the control path leading to these points, this kernel has trivially exploitable DoS problems. Creating threads doesn't require a capability, so at least the thread allocation is a clear DoS.

Because the shell is a generalized engine for executing things, and because magic defines textfiles as candidate executables nominating either the shell or a shell-exec binary to interpret them, and because system() jacks all of this to say you can invoke a shell with all its awesome to invoke scripts which invoke a binary to parse them.

If the shell was only rsh, and if the set of binaries you can invoke was constrained, and if the network and system calls were accessed through strace() barriers which limited what you could do.. We might have less problems. Except that in the end, people don't code or script for secure execution so the context of 'what harm can I do from here' turns out to be a lot wider than many people think.
Not following you here. What do you mean by "The map is not the territory."..

What I mean is that. Do not "teach" the thing in real time. Instead collect the sensor data from the cars a human is driving (and also collect the human input also), and train the thing on it, safely inside the lab.

You say, they have done it already. But I am asking if they have done it enough. And if that is so, how come the accidents such as these are possible, when the situation is pretty out of a text book in basic driving?
So, you want high engineering salaries, and the inability to get fired?

I'm not strongly for / against unions either way, but something here doesn't seem like it's compatible. Is it completely crazy that a company doesn't want their high paid employees to be hard to fire when they perform their jobs in a way they don't like?

From the story, it doesn't sound like fundamental rights were being violated. People's wages weren't being stolen, their healthcare wasn't being shut off.

The employee starting the whole thing could've been combative, uncooperative, etc. Who knows what it was -- those things are totally within the rights of a company to fire someone over in CA. And using outside messaging clients on company equipment, so is that. So what you're advocating for is to be allowed to do things that are honestly, privileges, and within the rights of a company to object to, but not face any consequences?

I would also pose the following larger question: Silicon Valley / this environment for investment and technology incubation exists because companies are allowed to decide who they want to employ or not, what ideas they want to try or not. Would you have found employment in this sector, if companies were forced to hire and fire using union rules?

And how would working under a union work? Would you initiate a grievance process for every gripe? Would companies have to build up a case about your poor coding quality to be able to fire you?

I don't see it working.

I apologize for somewhat conservative views in this area, but my thought is, you live in one of the highest paid areas, with the chance to hit it big as an employee of a company like this, you accept the risk that it won't work out.

If there were some golden company that paid well, couldn't fire people, and worked on everything you liked, well, wouldn't we all be there?

If all the steps are done at the same time and one of the steps fails 5% of the way through you have only wasted 5%.

I get that they are measuring the spacing and loudness of his drumming, specifically how he hits the hi-hat instrument. As expected with any human player, there are fluctuations. He speeds up and slows down. He hits harder or softer.

It sounds like they have found a pattern, and that's the part I don't get. These phrases seem central:

1. long-range correlated (LRC) fluctuations

2. detrended fluctuation analysis (DFA)

Yet I can't figure out what these mean, even after reading about them in Wikipedia too.

Right, but your original statement was about clock_gettime, hence my confusion.

Something like sleep() is an operation on your own schedule, not an operation on a global system clock. That's not nearly as problematic.

Consider if you wanted to virtualize a process, say to deterministically replay it to trigger a fault or something. sleep(100 ticks) doesn't require additional kernel support for virtualization, but an ambient clock requires a lot of extra kernel support.

If the clock were only accessible via a handle, then you could proxy invocations on the handle without any extra support in the kernel. See my other comment for more details: https://news.ycombinator.com/item?id=16817462
I suspect that like most “magic” solutions to environmental problems, this would cost significantly more than just reducing CO2 emissions.
All lossy compression algorithms hallucinate. That's the whole point: reducing image size by dropping some information and then hallucinating a plausible replacement to decompress.

The only difference is that this compression is better at hallucinating, so you don't get ringing artifacts or blocks, but some internally consistent alternate reality.

If you don't want to lose data you should not use lossy compression at all. JPEG can erase the distinction between digits as well.
That's a very naive comment. What if there's no emergency lane? Should it just crash towards whatever is on the right side of the car? :)

Tesla's autopilot already slows down then stops moving if the user doesn't touch the steering wheel for a period time, but it gives plenty of warning to the user before that happens, as it should be.
People don't really understand what the terms 'up' or 'down' mean, in general. Down is the direction of the sum of the gravitation forces. That's why things fall down.
The brain doesn't care about up or down location of nerves, because it is not affected much by gravity, it is held in place. If a nerve is above or below another, the brain doesn't care.
On a side note, you should also realize that the direction 'down' is dependent on your location, unless you are on the discworld.

Kindof an interesting legal question - what would make peepeth more liable for such data more-so than etherscan.io for example? If both sites have the feature to hide or prevent download of the data, whereas etherscan may not even bother?

It kinda makes you wonder if the Ether wallet itself that can sync and download such data is also at risk of being called illegal.

Are FBI raids now going to focus on targeting people that have a copy of the block chain to put them away?
It looks like the actual data is stored in IPFS; who is responsible for pinning this data so it sticks around? Is the centralized peepeth.com service also a de facto centralized host?
Cool, that sounds like a reasonable approach. I like the idea of a series of cheap buttons that can connect to a central hub in the home. Couple of questions though:

1. Do these buttons have their own power supply? If so how long does a battery last?

2. Is their a secure radio channel of communication?

3. Is their any feedback on the button that the computer received that button press. (To avoid multiple presses)
