It hasn't because the Flight Computer represents a single point of failure in a system with a catastrophic consequence of failure. This is not allowed. If it's even possible in theory but unlikely, it doesn't matter, it has to be redesigned. That redesign alone is likely enough to violate the little or no training required that was the original intent of the resign.

Note, these weren't "newly stringent" as if they've never been done before now. Worst case scenario bit flips by cosmic rays are textbook test cases in aerospace projects. That they weren't considered before then is a marked demonstration of lack of due-diligence or follow-through in enumerating the fault-tree.
What is the best argument for why this intervention is necessary? If workers don't like the pay, they can quit. Given that workers can always quit whenever they want for whatever reason (with the exception of certain high level jobs) how much regulation of the business/worker relationship is really necessary? Safety regulations, sure, but regulating hours and pay rates etc etc? Does this actually benefit anyone?

The indigenous Australians used to start fires at a specific time of year for the particular area, and on a particular cycle of n years for a particular area. Some of these cycles and times are known. This meant that, for thousands of years, the fuel load in the eucalypt forests were reset on a regular schedule.

Not only do we not do this anymore, the schedules that worked for millennia probably wouldn't work any more due to the change of rainfall patterns, temperatures and moisture content.

Indigenous Australians certainly would have seen some huge fires, but according to soil / sediment and tree sampling, probably nothing like the ones going on right now.
The EU is increasingly fining and cracking down on tax avoidance. Seems like things are headed in a good direction, if slowly.

You can live a car-free life in Austin (as I do), but that does not make it a good city to do so in.

Austin as a whole consistently ranks low in terms of walkability and the public transit here pales in comparison to other major cities. Just because a small slice of the city occupied by the upper-middle class have the luxury of living next door to work does not a good city make.

Subjective guidelines lead to subjective outcomes.

“Responsibility” and “respect” are vague ideas with no objective measure of what is allowed or not allowed. If society agrees we must stop something, the only way to do this is with specific, written law. Not shifting, vague moral platitudes.

Over-regulation is just another way to say “poorly constructed law.” We need to write better laws (or change the process for writing them if they are consistently mis-representing our intentions), not less laws.
Yeah, this sort of thing is far from unique to Facebook, and is why it's been my practice for many years to never just click on a link. Instead, I copy it so I can strip out all of the unnecessary decorations and trackers before browsing to it.
If they got paid an hourly minimum, I don't see why someone would want to drive for other platforms. The only reason people drive for multiple platforms is because it's needed in order to consistently make money. Other than maybe to slightly optimize the max amount of money they make, I can't imagine why someone would continue wanting to drive for multiple platforms if they were w2.
Ask HN: Why is there so much hate for Google?
Long question: Ask HN: Why is there so much hate for Google (yet, lot of folks want to work for Google or one of the FAANG companies)

I see lot of hate for google and it was very evident when google acquired Fitbit. Lot of us wanted to just rid of pebble. Yet, I see lot of people trying to get into Google (or one of the FAANG companies). I saw it from Blind app posts but I understand demographics of Blind vs HN is different.
This doesn't work like that. Containers (like docker, LXC and other based on cgroups etc) are isolated by the kernel but they share the same kernel. This means that kernel exploit will make all those containers insecure by your definition. If you go further and try to embed containers in hardware virtualization layer (so basically mini VMs) you still don't have any guarantees because from time to time new exploit emerges that allows to break out from guest OS to hypervisor.
Then you have hardware layer and exploits based on speculative execution (Spectre, Meltdown and friends).
Truly secure container doesn't exist. You would need some kind of mathematical proof for whole hardware stack and all communications between different hardware subsystems + whole kernel + container runtime.

You might want to look into trying an elimination diet. There are quite a few resources online for this and gist of it is that you cut out a whole bunch of food types that have been known to cause issues with some people. After a few weeks of that you add back in a single group of food every few days and check if any symptoms return.

Some people have had luck using this method to find issues that doctor visits weren't able to surface.

Ottofield ( https://www.ottofield.io/ )- Conversational Scheduling for Home Service businesses.

The idea came from being in the trades in my previous career. Companies in the trades spend a ton of money on advertising but fail to capitalize on a lot of their incoming leads. We use humans to answer incoming text, fb messenger, and webchat questions for people like electricians, hvac techs, plumbers, etc.

Long term idea is that as we get more data on how these conversations typically occur, we can build some ML systems to lower the cost of answering the questions.

It's still MVP stage right now. Got a few customers and planning on ramping up marketing in January.
But replacing "corporations are supposed to maximize profits" with "corporations are supposed to fund the president's trips to his private golf resort" hardly seems like a step in the right direction.

Without contextual detail, paying more than the minimum taxes required by law is not necessarily the moral choice.
My point is basically that at minimum 50% of the taxes foregone to support the 401k system[SEE EDIT] is going to people who definitely would have had an awesome—not just OK, not good, awesome—retirement no matter what. Not the poor or middle class. Functionally no-one in the middle class is getting five figures of contributed funds per year from their employer, let alone the ~$36k it'd take to max it out. Who are? Top-end professionals who can be self-employed in such a fashion that they own their "employer" (and again, LLC or partnership won't cut it, because reasons) and very well compensated corporate folks (chiefly management-tier). Plus family of rich people who're just (legally, but clearly via Some Real Bullshit) dodging taxes.

[EDIT] OK so 50% is not necessarily right, obvious, I realized as soon as I posted, but the benefits are very disproportionately in the favor of people who aren't exactly the ones one might hope a government-supported retirement system would be mainly designed to help, and the best possible benefits aren't practically available at all to middle-class people even if they do somehow manage to put the actual total contribution limit away for retirement (they'll lose out on probably at least half the max benefit of the system, since they can only put ~$19k or $20k in tax-free themselves and probably only get low-thousands contribution from their employer at best, so the rest is getting taxed before being invested, and IIRC you can't even stack an IRA on top of a maxed-out 401k contribution)
I'm interested in IPv4 in IPv6 and vice versa, TCP in UDP and so on for the data-plane. Imagine something like TailScale.com [0] but managed and not P2P, or maybe running something like Wireguard from within a unikernel. I'm not even sure if it is a valid use-case to have long-running unikernels? Also, does that count as NFV/SDN? Currently, I run the data-plane workload isolated via VMs and they are always-on, even when the traffic is non-existent.

The requirement for HTTP workloads is mostly for control-plane APIs, and imo, Workers will work really well, for that.

I think what you are missing is that "greed" is in the eye of the beholder. Of course a business magazine never worships the "greed" of a great businessperson, but they do worship a person's ability to make huge deals.

America definitely worships actions that many would consider to fall under the "greed" term, even if you don't. A great example is that Donald Trump's main qualification for being President was his wealth and business acumen. I think half the country would consider him a poster child for "greed" while the other half think his actions fit in on a resume.
When I had hair, I just rinsed it under water. Water is already a pretty good sovent, but isn't nearly as aggressive as detergents in shampoo.

Nobody I knew realized that I didn't use shampoo. I told lots of people that I didn't use it and they were shocked that it was even possible. My hair was fine. They weren't just being nice. I also discovered that a few other people in my social circle also didn't use shampoo, including some women with longer hair. I'd have never guessed.

The scientific method demands replication, and we've talked an awful lot about papers being published that can't be reproduced.

When it has been replicated it's theoretical science. But it's still a variant on the XKCD joke about how everything (including guns) kills cancer in vitro but that doesn't mean you can use it to cure cancer.

Lab-only experiment might clue the next person into a phenomenon that can make it out of the lab. But making it news when it hits the scientific journals has been a sore subject for a lot of people, and seems like it always will be, and that it might even get worse before it gets better. We call a lot of things 'science' that haven't followed the scientific method, and it's exasperating.

This is not the first time materials sciences people at UIUC have looked at self-healing materials. Twenty+ years ago they were looking at lacing concrete to repair small cracks. Really cool stuff... that has not made it out of the lab as far as I'm aware.
I'm not sure this is in fact true. We have experiments going on at the state level. People have a higher standard of living in states with less regulation.

IMO I would argue California's new law is not about protecting workers, who are actually able to earn more money as independent contractors, but about protecting higher tax revenues collected on employees.

In San Francisco where I live, we have almost no middle class primarily because it's so expensive to live. Thats right no middle class. We have effectively outlawed housing with 7 year approval cycles, and exclusionary zoning. It's nearly impossible to develop in California.

What does the data show? People are leaving California to move to states like Texas. Half of Californias are thinking of leaving the state. Poverty is shrinking everywhere except California where 18% of the population is living in poverty.
The "gig economy", aka the "income inequality economy", or the "we need multiple jobs to get by economy", or the "human labor as commodity economy".
> there's no exclusivity

If there were a middle ground between independent contractors and employees, where such "dependent contractors" e.g. worked exclusively for one client, I'd bet some drivers would pick teams.

A middle ground for contractors makes sense. It makes more sense than the status quo, where ersatz employees get no benefits. And it makes more sense than the Californian law, which effectively outlaws freelancing and part-time contracting.

Such a middle ground relationship would involve some obligations of employment (e.g. re-imbursement for expenses, paid sick leave and time off, basic health benefits) but not all (e.g. no retirement accounts, limited dismissal recourse, no training), just as it would entail some of the restrictions of employment (e.g. exclusivity), but not all of them (e.g. no gardening leaves, corporate NDAs, time management, et cetera).

Luck manipulation is only possible in more recent entries by exploiting game-external factors like the system clock. But, in any case, when it comes to comparing games implemented in software (like Pokemon) with games that aren't, you have to distinguish between "the game" and "the software". The Pokemon game is designed to be non-deterministic from the player's perspective, regardless of the fact that the Pokemon software may be deterministic in some detectable or manipulable way. Just like craps would still be a game of chance even if you figure out how to fix your rolls.
We once went hiking in a newly opened area close to Mt. Kosciuszko, which had previously been decimated by fire. The new growth was so thick and high, it took us 6 hours to walk 5km (3mi), all the while hunting for the pink tags left by the rangers that showed the "path".

Thermoelectrics have terrible efficiency, that's why they're hardly used despite the fact that waste heat is literally everywhere.

In theory, any heat-based powerplant could use them, but instead they all boil water and drive steam through turbines, which is much more efficient.
> AFAIK DMCA notices don't go through the courts. They're just sent to the site owner, who must comply or file a counter notice.

I think you're mixing two things:

* if a site owner receives a DMCA notice and believes the content is not infringing they can just do nothing and / or tell whoever sent it to get bent, sender may escalate to the courts

* service providers which want to be protected under safe harbour must "act expeditiously to remove purported infringing content" regardless of counter-notices, this is not an either/or situation

Content should be restored 10 to 14 days after the counter-notice is sent to the original claimant unless they engage in legal action, but it must be taken down either way:

Idea for HN: the balance of downvotes and upvotes on an article is a useful piece of information in and of itself. It might not be a good idea to show that on each particular article, but an end-of-year analysis of what words in an article title often corresponded to lots of downvotes (relative to the upvotes), would be an interesting way to measure which topics are currently hot-button issues.

You're ignoring the point I was making about capturing the infrared waste heat. It seems counterintuitive for a civilization to go to the effort of encasing their star in a shell of satellites while dumping energy as waste heat. Surely there must be some way of utilizing that energy and my conjecture was that advances in the efficiency of the Seebeck effect might lead to a way to fully utilize that waste.
