I believe coinbase holds a lot of crypto - in the robinhood analogy, coinbase is their own clearing house. So they don't have to post collateral to themselves, but if crypto movement was all in one direction on a given day, they might rely on the market instead of the liquidity they themselves provide. Maybe in such a scenario they would be clever enough to NOT resolve all the trades instantly.
The upside is much smaller though. There are lot more drivers than pilots, and crashes are so less common.

Alphabet’s Waymo CEO John Krafcik to Step Down, Will Be Adviser
SHARD | PORTLAND, OR | PARTIALLY REMOTE

Shard is a scrappy, boutique web development agency based out of Oregon – we build focused, market-ready prototypes for venture-backed startups and Fortune 100 companies (JPMorgan Chase, MetLife, KPMG) alike. Last year was our best year to date and 2021 is starting off very strong.

We're looking for an opinionated engineer who doesn't like being trapped in a single codebase and enjoys being able to context-switch between projects. Tech preference isn't important for this role, but bonus points if you're dangerous across the whole stack.

Salary: $100-160k

Great news! France gets 70% of its electricity from nuclear power, and it's a very plausible part of the solution.

Relatedly I've been thinking about how to compare the moral culpability of anti-nuclear activists for climate change to that of oil companies. Are sins of preventing beneficial action comparable to sins of taking harmful action? Do intentions offset effects?

What happens after another century of dumping 45+ billion tons of CO2 and other GHGs into the air?

The question is whether it's better to use nuclear power or fossil fuel power. There's little difference, practically speaking, between hemming and hawing about statistically small events happening re: nuclear power, or what we do a lifetime from now, and actively advocating for increased fossil fuel usage.

If nuclear can be replaced with something even cleaner and even safer then I'm all for it. But it's short sighted in the extreme to actively tear nuclear down when the only realistic alternative at that scale is fossil fuel.

Article is about stocks, so the fact that governments aren't consistent in protections compared to other areas seems a bit off topic.

That said, whenever the failure to protect carries a very high cost one would hope those things would get weighted more heavily when protections are considered. Supplements in particular are interesting in that they appear increasingly _designed_ to skirt existing regulations. And as more and more are found doing significant harm the governments of various states have starting paying more attention.

People making self driving cars are basically putting infants in the drivers seat.

I think the condition for having this sort of software is that people do it on purpose. The condition for having jobs where people are paid to make such software is that companies focus on areas without competition (otherwise the whole blitzscaling thing applies and they will go out of business). Competition is for losers, right?

Referring to scientific theory as science fiction is a bit strong. The extinction of the dinosaurs isn’t Star Wars. Can we ever know exactly what caused that extinction event? No. Did a massive meteor hit the earth that likely could have done it? Yes. Could some other coincident event also contributed? Sure. There is, however, pretty strong modeling-based evidence that the meteor strike alone could have caused the mass extinction.

My point is that we are talking about an event that happened 70 million years ago. Think about how long ago that was. The amount of evidence that is leftover after 70 million years of time passing is infinitesimally minute.

To think we can come to any conclusion with the tiny amounts of evidence that remains or to clue together all the remaining bits and pieces of residual evidence is extremely arrogant.

It makes for a decent story and hypothesis, and it sounds plausible. But to teach people that this is basically fact is absurd, which is my point. It should be taught as a theory.
They are picked before they are ripe and they are artificially ripened, like bananas. They are cultivated for fast growth and maximum size, and not given time to mature.

If you grow your own tomatoes, the results can be amazing.

30 years ago, my grandmother grew the most amazing tomatoes in her vegetable garden on the farm. When she died my uncles sold off the farm and a developer split it into 5 or 6 plots that are now mostly horse pastures with huge McMansions on them. So it goes.
Well, in part due to the nuclear weapons programs, the US and Soviet governments told a lot of lies about nuclear energy in the 01940s, 01950s, 01960s, and 01970s. A lot of the science on things like nuclear fuel enrichment isn't actually available publicly, even today, only to people whose families have been interviewed to make sure they will lie if the government orders to.

So the US Secretary of the Navy is in a position to make an informed decision about nuclear reactors—and he's chosen to run a significant part of the US Navy on them—but the voting public is not.

Maybe get your iron checked out? I have iron issues (overload) and noticed the spike after Covid was really intense. If your 'heaviness' is on the right side it could be liver swelling. All cold/flu will give you a spike like this because your body absorbs all the iron from the cells that died. It throws off your balance of circulating/stored iron for a while. Normal people won't notice it but if you have iron issues you will. But this is just a guess too, I am also not a doctor.

Great info in the article.

Had something similar. The firmware update of my sse4200 NAS has stopped and its NetBios version is badly outdated. I was looking for an inexpensive way to reuse the disks to build another NAS. After looking around a bit, ended up getting a RAID capable DAS enclosure for the disks, repurposed an old Chromebox to connect to it via usb, installed Linux, and shared over SAMBA. It works well.
In a competent society, yes.
They received a report of it being exploited? Hopefully not too widespread

Here’s the thing - if it relies on a central authority to say “this is the genuine article” why do you even need a blockchain? A PGP certificate or X.509 is arguably “a cryptographic representation of something unique”

EDIT even something like a domain name - which is arguably a better example as only one of such a thing can actually exist in that only one owner can derive the value from it.
You’re missing the last bit, though. It’s “believe the science, when the science agrees with my ideas”. The truth is, a lot of those people claiming IPCC should be listened to conveniently ignore the bits in the IPCC reports that don’t align with their opinions. Also, nobody has time to read the reports and spend years training to actually understanding them.

We are overall woefully uninformed about these things, to the point that the majority of people in some recent opinion polls in Europe believe that nuclear power plants emit greenhouse gases.

Sigh. Yes, ANYTHING can be one line... if you're allowed to call tens of thousands of lines of code compiled in a different library.

Yes, and the methodology I've described (whole brain emulation/WBE) is the worst-case, brute-force, but guaranteed approach. The following diagram captures the expected growth rate of computing power, and contrasts it with several thresholds (in blue) for emulation fidelity ultimately required: https://en.wikipedia.org/wiki/Mind_uploading#/media/File:Who...

The human brain works, therefore this technique will work, it's just a matter of having enough computing power.

I will re-iterate though, we are pursuing various alternative pathways to artificial intelligence, and modern machine learning has already demonstrated super-human performance within constrained domains. It's my personal belief that we will achieve human-level general intelligence long before WBE becomes practical.
More context on the -no safety driver- issue.

"Eliminating the safety driver is an important step toward making Waymo's service profitable. But it may not be enough on its own because Waymo says the cars still have remote overseers.

These Waymo staffers never steer the vehicles directly, but they do send high-level instructions to help vehicles get out of tricky situations. For example, a Waymo spokeswoman told me, "if a Waymo vehicle detects that a road ahead may be closed due to construction, it can pull over and request a second set of eyes from our fleet response specialists." The fleet response specialist can then confirm that the road is closed and instruct the vehicle to take another route."

Or the discussion is about nuclear versus other forms of "green" energy.
I support including nuclear here too, simply because nuclear is only useful in a culture war.

New nuclear is a complete financial boondoggle. I'm always surprised to find any libertarian support for it however, as nuclear is the project of big government. It requires massive financial insurance that only governments are willing to provide. And in the US, it has been such a financial disaster that utilities run far away from nuclear for fear of bankruptcy. The only way that we started two new nuclear construction projects in the mid 2000s was because the state legislature was bought off, and allowed utility monopolies to charge customers for the construction of the project whether or not it finished, completly socializing the financial risks of construction through government force. And in South Carolina, the after spending $9B of utility rate payer money, the project was abandoned as in feasible to complete.

So the libertarian support for nuclear always has me completely puzzled. Without government coercion, it would never get built again. But then, I'm the complete opposite of a libertarian, so I'm probably misunderstanding something of the motivation. I would be interested to hear how a libertarian could support a new nuclear project.

Surely the Belgian government is free to decide how to enforce copyright law within Belgium? It's not like copyright is the same the world over. I'm from Canada for instance, and we have very different fair use (fair dealing) laws from the US, different copyright terms, etc.
I got reasonable offers from 2/3 companies I went on-site with from Triblebyte. I found that their stable of companies had too many tiny startups with questionable (read: boring/dumb) product ideas. I wanted a company with 100-300 employees so not many of their partners met my criteria. I found their recruiting partner that works with you kind of annoying... I didn't appreciate them texting me/"checking in" all the time. It's bad enough to deal with the company recruiters doing this, I don't need another cook in the kitchen. Overall, I didn't think it was a waste of time but I don't think I'd use it again now that I know that they mostly represent smaller companies with advertising/fintech aspirations.
I think it's a pretty mediocre language because of the compiler intrinsic data structures and functions like maps and slices that cannot be created by the language proper. It can be verbose and tedious, some of the std lib stuff like "context" ends up "infecting" everything (ala async/await), variable shadowing sucks, still has "nil" instead of something more modern and safe like Rust's Result<T>, etc, etc.

If I had designed this language in a "design a new programming language" college class, I'd probably have gotten a C+ for my efforts at best.

What Go is, is a great tool more than a great language. I like to use it because my output from it is usually reliable, is on time, is light on resources, is easy to deploy, and allows me to get kudos at my job and more $$$. It's wonderful screwdriver for today's screws.

But I don't think it's a great language the way a LISP is a great language, or Smalltalk, or Haskell, or OCaml. It won't really open your eyes to a new way of thinking about problems that you didn't already know from your C days. You still have too much interface{} stuff everywhere, or reflection (which is extremely tedious) or pretty-awful code generation compared to LISP macros.
Yes, it's as much of a choice as when I put a gun against your head and ask you to do me a favour.

The "choice" is based on literal state violence. Both in internationally enforcing intellectual property laws (with your military) to force you from buying medicine and other crucial supplies from the US, and from using violence to prevent those from being sold.
I would hazard a guess that fork is nowadays implemented by the clone(2) system call, which does use copy-on-write depending on its arguments.

It's possible that there are deep assumptions in the Linux code that some fundamental software or hardware memory handling capabilities are present.
Even cooler is that this has apparently and unsurprisingly already been explored.
No, the physics of that don't work at all. Trains for example cannot handle gradients that cars manage with ease.
The difference is, regardless of political divisions, everyone in Egypt totally understands that they are doomed without water. so the mentality there is slowly shifting towards "well, if we are dying anyway...."

mnm is not mail – a legitimate email replacement
I know the MMU doesn't make eviction decisions, but it does mark the "dirty" and "accessed" bits for pages.

The GP was suggesting keeping track of the scheduling priorities of tasks that were "accessing its[the page's] contents", not just keeping track of the highest priority task mapping a given page. This would require the MMU, as it's setting the dirty and accessed bits, to also keep track of the maximum priority that has set either the dirty or accessed bit.

Edit: from the GP's reply, it sounds like by "accessing" they really just meant mapping, not accessing is the sense of the accessed and dirty bits.

> Garmin Autoland will take a plane which is otherwise working and is in the sky and put it back on the ground because the pilot has a problem...

Indeed. For reasonable values of "land" and "on the ground." It's better than a non-trained pilot, but it also relies heavily on the concept of "emergency" in aviation, in which everything else is put on hold and everyone else gets out of the way.

It has basically nothing to do with driving a car.

First, the sky is large - "Big Sky Theory" is the term for it, and it generally means that you can fly around however and wherever you want without hitting anyone. Yes, there are controlled airspace segments, various levels for flying around, but the reality is that if you just ignored all of that and flew a plane from A to B, you wouldn't hit anyone (almost always). It breaks down a bit around airports, and there have been the occasional "plane A not talking to anyone and plane B not talking to anyone colliding" events, but they are exceedingly rare.

Second, large airports are going to be (almost by definition) controlled airspace, with ground response crews. And there are common airbands for radio communication. The Garmin system relies on these things.

If you hit the "Oh Crap!" button, yes. It will control an otherwise operational plane down to landing at some airport (I believe it prefers controlled airspace and emergency services, though I don't know details), and it will clear the road in front of it by setting the appropriate emergency transponder code and broadcasting prerecorded messages on the appropriate frequency that basically amount to "Get out of my way, I'm coming in for a landing at this airport on this runway." Which, for an incapacitated pilot, is absolutely the right thing to do. I'm fairly sure it won't clear the active runway, though. That's a problem for the humans on the ground.

But - literally everyone else in the sky will get out of their way, and ATC will ensure that. If there's an A380 on approach and this system is triggered near the airport, if ATC needs the A380 to get out of the way, they'll tell them to go around and go hold somewhere until the Cirrus is dealt with.

It's really a very, very different class of problem than self driving cars.
> hundreds die for unnecessary elevator deaths yearly

Elevator deaths are extremely rare in industrialized countries (a couple dozen per year in the USA), and most are of people working on the elevator (e.g. accidentally falling down the elevator shaft), not passengers riding in an elevator. I think construction elevators are also quite a bit less safe than ordinary passenger elevators.

Typical elevators are one of the safest forms of transportation, substantially safer than stairs or ladders.
