I don't know of any HPC facility that aims for/achieves anything beyond 99% uptime, most well-run ones are probably 98%-ish.

And that is just raw uptime, as an end-user you also have to live with you jobs waiting for the scheduler to fit them into the queue. A day or two waiting time is pretty common on larger jobs.

Our vervet monkeys in South Africa will often do this but not always. When they steal fruit from our kitchens, they seem to take bites out of each item in their haul, then run off, sometimes with their favorite one.

I'm guessing abundance is one reason, similar to how predators in a glut will eat the liver, and other high value meat before moving on to new prey.
> It’s not relevant. Is anyone expecting him to be the CEO?

The article quotes a shareholder rallying behind Musk's offer as justifying his support for Mr Musk's personal involvement.

The article includes quotes from shareholders such as “He has an established track record at Tesla,” and “He is the catalyst to deliver strong operating performance at Twitter.”

I'm not aware of a single instance where shareholders were excited by the prospects of the new owner delegating managent to a random unknown employee.

How to Quiet Your Mind Chatter (2021)
For GPUs, very well I would say. If you have an NVIDIA GPU, all that's needed to use the proprietary driver is:

{
nixpkgs.config.allowUnfree = true;
services.xserver.videoDrivers = [ "nvidia" ];
}

(see also https://nixos.wiki/wiki/Nvidia)

For embedded systems the roads are certainly less traveled. There is decent support for several popular ARM SBCs (https://nixos.wiki/wiki/NixOS_on_ARM), and you can get it onto others with some elbow grease. The official binary cache only provides binaries for aarch64, so you will have to compile everything yourself for 32-bit ARM.

Calling somebody a pedo because they insulted your work on TV is unstable behaviour. So is repeating the claim to journalists and saying explicitly you really literally meant it, throwing more insults in, settling the libel case and then repeating the claims again. Actually, unstable is one of the nicest adjectives you could use about this abhorrent behaviour.

Your defences and explanations are all irrelevant and rely on minimising it as "saying something bad" and "on Twitter". That isn't adding anything to the conversation.

I find that a lot of things are really DAGs or full on graphs but are easier to reason about as roughly trees. Website structures, for example. All knowledge, even. For some reason, trees are so much easier to hold in the head.
Previous downturns like the 2000 dot-com bust led to layoffs, reduced bonuses and other perks. More people looking for jobs after layoffs or the former employer going bust meant more competition for fewer jobs and lower offers. Some companies cut salaries across the board.

Layoffs often come down to managers working with a budget goal and choosing who to let go. Anyone with a really high salary may find themselves more vulnerable at such times, especially if projects get scaled back at the same time. Surviving rounds of layoffs means having indispensable skills and a salary not so high that replacing you looks feasible.
UK's first driverless buses take to the road
But the Landauer limit, even at 300K, for a first preimage of even a completely secure hash is essentially zero. Define:

f(s, n, h) = 1 if there exists an n-bit preimage of h that starts with s, else 0

Computing f by brute force costs one bit erasure to prepare room for the answer. (And takes 2^(n - len(s)) operations, but we’re imagining a civilization that can build Dyson spheres and has quantum, and hence at least somewhat reversible, computers. We’re talking about the Landauer limit in particular.)

Now choose an appropriate n (slightly greater than the length of the hash) and compute f for s=[0] and s=[1]. After at most two tries, you’ll get a match, assuming a preimage exists. Call the first match s_1. Now repeat for s_1||0 and s_1||1. Call the first match s_2. Repeat this up to s_n. Now s_n is the lexicographically first n-bit preimage!

This costs O(n) energy at the Landauer limit. All crypto is broken! Never mind that the actual computation involved exceeds 2^n.

I've had a terrible experience with lsp-mode, gopls and Emacs 27. Minor issues like inconsistencies and CPU/RAM hogging that requires manual restarts, and the major one that made me stop using it is that Emacs would frequently crash when editing Go files.

I reported this to lsp-mode, but they kicked the can over to Emacs[1], which I never bothered reporting. The fact this is now a combination of tools with no clear reporting path when something goes wrong is awful UX.

Every few months I update the entire setup with hopes things improve, but eventually I always get the crashes. I would really like for this to work, as the DX when it does is great, but for me it's just not there yet.

> The odds of a cohabiting couple with children breaking up was more than seven times as high as for a married couple who had not lived together before marriage, and more than four times as high as for those who had lived together but went on to marry.

I wonder how the researchers control for the effects of external factors, like the family's economic wellbeing?

After all, a family that is struggling financially might be less able to afford a wedding; might have more to get into arguments about; and might have less money to spend on their children. But I'm not sure how easy it would be to control for that.

Founders are CMU students; presumably the rest of the schools on the list are various name-brand private schools (plus Berkeley). Texas (and Illinois, Michigan, etc.) are notably missing from this first round list; that's the founders' loss.
The understanding of the original real-world problem, the very idea of a solution, and the language-agnostic mapping of that solution to program architecture (making good use of existing patterns and algorithms[0]) is the genius, the core value of high-level programmer’s work.

These ideas, as well as the appropriate external context, can be captured using any medium, be it analog or digital, since no one came up with a better way to convey it than text and possibly some diagrams.

It is part of the reason I consider well-written and well-structured high-level documentation more critical than tests or even functioning program itself. The latter are lossy, narrower representations.

[0] If there is anything novel as far as specific patterns and algorithms involved, they can be appropriately formalized and documented in isolation of the larger program and also in a language-agnostic way.

UK notionally comes up as an example, but it really isn’t. There are 5-10 parties in the House of Commons, but only two that count for anything in terms of seat count.

the apps i work on don't collect "behavioural data", so i don't have a strong opinion about it. however i think there are some crucial differences here.

1. sentry.io breadcrumbs are just a nicer interface to one's own log messages, and log messages are useful and necessary to have a well functioning app. where do log messages end and profiling/behaviour data begin? that's a rather fuzzy line.

2. even if one "logs" every breath the user takes (probably covered in the ToS), it's still only limited to one app and one service, while cookies are trivial to abuse for cross-site/cross-app tracking both inside and outside a company.

> As for examine: I know how j.u.c works down the OS calls and generated assembly.

And here's the big reveal. It's actually calling the OS for "setting the current thread to sleep and being awaken" ie it's just using the OS locks and those are hidden from you so that you can't garbage collect them.

> Unsafe is a class (not an interface), albeit mostly resulting in compiler magic.

Unfortunate choice of language, I didn't mean a Java interface, but an interface in the broader sense. I assure you that "setting the current thread to sleep" is not "compiler magic", it's just using the OS locks, on a modern system it will presumably use a lightweight lock but on older systems it'll be something more heavyweight like the semaphores we saw earlier.

The claim that LockSupport, which is calling the OS is not a wrapper is bogus.

But all this is a distraction, even on systems where old semaphore APIs are now rarely needed they still exist and if you hold one you are still responsible for cleaning it up properly even if you think you know better.

"China" didn't do that. The Chinese people did that after Deng Xiaoping got into a position where he could stop the government actively destroying all progress in the country.

And whilst I used to be impressed by this "lifted a billion people" take, the reality is that lots of countries industrialized, modernized and huge numbers of people left behind agrarian poverty. This isn't unique or special and in fact when ranked against other countries like Taiwan, Korea, Japan - let alone countries like the USA or UK - China has turned in one of the worst performances. China still has widespread poverty and in many ways is still a developing country, 80 years after Europe utterly destroyed itself in WW2 and Japan had two of its major cities leveled by atomic bombs.

There's really nothing impressive about China beyond the sheer number of people the government has managed to hold back. If your foot is constantly on the brake of a very large vehicle, lifting your foot even half way will cause a lot of mass to start moving. That doesn't mean you get credit for it.

This is the key phrase from the entire thread. PAR2 will enable the user to create recovery files, if (actually, when) part of the original data will be corrupted. The recovery files (by default 5% the size of the original files) should be stored alongside the original files in each location.

Yes if you ignore all the times when it doesn't work, then lockdown works. It's an irrelevant tautology with no intellectual or scientific merit.

There is no Shanghai exception for lockdown as a scientific policy, just like there is no Swedish exception. To decide if a policy advertised as based on universal biology is working you need to evaluate all the evidence, and cases where it doesn't work either disprove the theory or require refinement. As nobody can come up with a plausible refinement that means it's disproven.

I guess you're right. Salmon isn't native to NZ and I believe we only have 1 species. However the way it's farmed in NZ vs the rest of the world is quite different as we use our fresh water rather than onland farms, and because plans to extend the freshwater farms were cancelled we are able to keep our water cleaner as we have fewer farms and no overpopulating.

Salmon is bloody expensive in Singapore.

https://songfish.com.sg/product/salmon-fillet-skin-on-fresh/

It's arguably the most important step -- the fluoride has antibacterial effects and it's that phase post-brushing where the fluoride becomes fluorapatite and bonds to your teeth. Using toothpastes like Biomin which are really neutral in flavor makes it significantly easier, the hyper-flavoured menthol toothpastes on the shelf are much, much harder to bear. Neutrally flavoured toothpastes, especially after spitting out the excess, would leave a texture in your mouth similar to what you would experience after drinking a bit of milk or something, so nothing you'd really notice immediately and you'd completely forget about it after 30 seconds.

I watched the videos about this, and compared against the videos of GoogleX Wing. I just don't get how they can be so different, or more precisely, how or why Wing is doing what it's doing.

This Zipline stuff is launching simple, low-cost vehicles, dropping very valuable (even life-saving) things from parachutes as simply as they can.

Google is launching very complex (part helicopter, part fixed wing) aircraft, lowering $5 coffee drinks to people so it doesn't spill.

How can it be so different? Do they just... have too much money and are over engineering something because they can? or have lost the plot? Or will they eventually get into delivery of some good that will justify the cost?

Or maybe I'm being a little harsh and it's just a reflection that in developed countries, life-saving needs are already taken care of quite well at the local level and all we have are coffee drinks to satisfy people's urgent desires nowadays.
The question remains. Do you think that the Western upper middle class are being willfully blind to some sort of domestic violence epidemic happening all around them, the way you describe previous generations as acting? You're relating isolated anecdata, that tell us nothing about whether some behaviors might have been common in the past.

> SSDs have a lot more aggressive error correction than most filesystems

Most filesystems do not do any error correction. ZFS, btrfs, ReFS, bcachefs are a few notable exceptions. And for the most part these schemes are for multiple device resilience - which is architected quite differently from the schemes used in an SSD or tape (yes, even tape).

> Tapes at rest don't have to worry about that though.

This isn't really true. Pretty much every physical medium at the densities used in modern time requires robust error correction because all physical media has flaws either manufactured or acquired from wear and degradation. For instance, modern LTO tapes use relatively robust 2D Reed-Solomon forward error correction similar to DVD/Blu-Ray.
The what now? They didn’t invade us in August ‘68, they definetly won’t do it now, with the Americans on our side. And I’d ease it down with the warmongering rhetoric (again, “orcs”, really?) if I were you, because last time we thought we were militarily better than them, the Russians, we had our grand-fathers and grand-grand-fathers die horrible deaths from Odessa all the way to Kazan.

This is a former-USSR internal kerfuffle, it’s the “Yugoslav” civil war translated to the former Soviet space. Thankfully we’re a not a former Soviet republic. I wouldn’t want to live in Estonia or Lithuania right now, though.
Read! Your writing skill will usually trail your reading proficiency.

If you mean business correspondence, find a nice book on professional communication (which may have to be adapted a little for modernity.)

Here’s the balance: less words more concise (unambiguous) meaning. Don’t meander. Use bullet point structure if you must. Try to supply necessary details you think others will require without round trips.

It’s okay to write an email, and come back in some time and reread it before sending. Self editing is like good hygiene!
I think the Option example (despite being the one the author thinks may actually be useful) is the worst one, since it really only replaces existing pointer syntax with named functions, but offers nothing else (well, maybe the Take() call?)

A better function to add to Optional[T] / *T would have been Map:

func Map[T any, V any] (o *T, foo func (T) V) *V {
if o == nil {
return nil
}
v := foo(*o)
return &v
}

or, with Optional:

func Map[T any, V any] (o Optional[T], foo func (T) V) Optional[V] {
if o.IsNone() {
return Optional[V]{}
}
return Optional[V]{foo(o.Yank())}
