It’s interesting how the totalitarian crackdown worked so well for the first two years but now the dirty free societies have everyone immunized by infections. As for China - I’m not sure they can crack down on omnicron as well since it’s so much more infectious and they can’t afford anymore economic shutdowns.

> To me it seems absolutely physically plausible that cooling a hard drive to absolute zero would destroy its contents.

Cool, cool. It doesn't, but enjoy.

Why would you imagine this would happen? The magnetic domain is not affected thus, and neither are MOSFETs.

You're a mathematical physicist? You're the single least likely person on Earth in my imagine to say "oh, you reduced the speed of some atoms? That must mean magic happens."

What could possibly wipe a hard drive from the action of cooling it down?

.

> Why would heating it back up restore the information?

In short form "it doesn't."

You may be confusing that some heating processes create damage with the idea that warming something up will harm it.

As any schoolchild can tell you, DNA has survived billions of years on this planet, being heated and cooled somewhat rapidly throughout.

&nbsp;

> And by the way, thermodynamic irreversibility is related to entropy change, which is a measure of information lost.

This is a very "consider a spherical cow" approach to physics.

The reason physicists are made fun of on those grounds is that the abstractions they bring to the discussion are frequently so far divorced from the real world situation that by the time you start bringing the real world back to the discussion, their abstractions fall apart.

Real world objects that were not designed for durability have not suffered this damage on the timescale of a fifth of the length of the universe.

That things are irreversible and related to one another isn't much use when you look at the real world and the things you're describing aren't actually happening at large scale, even in uncontrolled natural conditions.

An insect that's been in amber for 500 million years typically has DNA loss on the order of ~5%. It has been exposed to a wild range of temperatures.

If you genuinely believe that exposing a hard drive to absolute zero would destroy it, help us understand why Voyager is still running.

Maybe it's because it's still a tenth of a degree kelvin above absolute, or something?
I dislike linking the official youtube domain. It is filled with trackers, ads, requires running various scripts, has bad privacy policy etc.

'yewtube' is one of the invidious instances. Invidious is an youtube proxy service through which a user can watch youtube videos without touching official youtube.
Source? I heard of this trick from Schneier, but I have not seen any documents saying the US government is using it. In my experience, 90% of the things people say were in Snowden's documents weren't, so I'm skeptical. https://www.schneier.com/blog/archives/2008/04/tracking_vehi...
Not GP, but I suspect that increased emotional maturity would prevent one from lashing out, overreacting, underreacting, being unable to emotionally support one's child, etc.

There never was a civil war in Ukraine. In 2014 - that was still Russian forces both in Crimea and in eastern part of Ukraine.

Russia got sanctioned since 2014 exactly for that.
Makes me wonder how many other cool projects out there never get discovered because they can’t get by the search engine gate?
While I don’t have enough knowledge of the wider implications of this, it does impact something I was experimenting with last year.

The FoundationDB rewrite would introduce a size limit on document attachments, there currently isn’t one. Arguably the attachments are a rarely used feature but I found a useful use case for them.

I combined the CRDT Yjs toolkit with CouchDB (PouchDB on the client) to automatically handle sync conflicts. Each couch document was an export of the current state of the Yjs Doc (for indexing and search), all changes done via Yjs. The Yjs doc was then attached to the Couch document as an attachment. When there was a sync conflict the Yjs documents would be merged and re-exported to create a new version. The issue being that the FoundationDB rewrite would limit the size and that makes this architecture more difficult. It’s partly why I ultimately put the project on hold.

(Slight aside, a CouchDB like DB with native support for a CRDT toolkit such as Yjs or Automerge would be awesome, when syncing mirrors you would be able to just exchange the document state vectors - the changes to it - rather than the whole document)
I could be reading this wrong, but the entire country of Sweeden seems to be using less power than New York (16mw vs 18mw).
For China, Russian oil price goes down, because Russia got no other buyers. And even before war Russia was selling that oil at loss. The more they sell to China, the better to the west.
On the other hand, this observation must be qualified as not necessarily generalizable to all teenagers and parents.

Sometimes a person may grow up and realize that their parents were indeed quite lacking, and be right in that assessment. I think this other circumstance is important to at least mention because children of objectively lacking parents can have doubts in their mind about their own judgment. In part because of this common trope of teenagers growing up and reflecting that they were foolish and their parents were wiser than they expected, in part because familial norms are so private that it's difficult for one to know what's abnormal for families in a harmful way.

Sometimes, what underlies painful experiences for children aren't parents actually making a wise decision, but plain bad judgment on their part.
"Exposure to stocks" is not the problem. Thinking you know which stocks to pick is the problem. Robots and random chance are better than human intuition, partly because of institutional manipulation of markets.
I don't think this article is right on the cause. China's biggest problem is, imo, the continued slow motion train wreck of evergrande and its real estate market collapsing. So much of China's growth was money sloshing around due to things getting built. But that seems to be harshly falling. There's hundreds of billions of debt hovering around default and the best these companies can do seems to be to double down on building and selling more buildings, which I sort of expect people don't particularly want to buy. General supply chain issues and covid affect this too. Food availability due to lower exports of wheat from russia and ukraine could cause an issue too.
The most common cases I run into are:

PDF by a mile. Copy / paste is usually an option, but not always. Sometimes I see embedded font tricks to prevent this. The copy goes well, but the paste is garbage due to the glyphs being indexed differently in the embedded font. For anything more than a trivial copy paste, the pasted text will include various extras that require some additional massage before the whole thing could be considered plain text.

Text contained in images. Early in computing I had a neighbor who would use low bit depth bitmaps to communicate with their family living in Asia. That solved all the common encoding problems from that time nicely. Thought it was clever.

These days, scanned documents and or people using images for more control over presentation are two common sources for plain text that just isn't.

For that matter, text on paper comes up a lot too. One has to run a program on it to recognize the text optically, or just type it in again.

These cases generally happen on a GUI too. Command line may be possible, but considerable skill and experience are required to make it happen without also investing more time and effort than the task seems worth.

All that said, my two preferred "general purpose" formats are plain text, like we are using here, and simple bitmap images.

Markdown is a format that can transport via plain text and that's great, but can get in the way depending. Same goes for CSV and the like. Normally, those are high value however. It all more or less survives a trip through, say Notepad or vi.

Same goes for the bitmaps making it through something like paint and it all being useful and displayable in a human readable form on most devices.

The moment it ends up in some application, the use value in that context may go way up because more things can be done and or done more quickly. The requirement for other parties to have the same software can and often does end up being a reason to render whatever it is into these two things.

For me, it boils down to whether it's read only, reference material, or if there is a need to extract parts of it, or process any of it in some fashion.
Just be careful in mixing the "best one at teaching" with the "best one at the level of detail and correctness". One is good for aha moments, the other for going into research. Depends on your needs. Similar to the question of "what is the best language to learn?". Depends on your needs.
Yea, from our huge perspective it's a bit strange to think about. Heating a pan means you're giving kinetic energy to the pan itself, the pan molecules are then smashing into the water molecules
My own anecdote:

I used to attend a nearby hackerspace. One day, out behind the building, we see a desktop tower machine thrown in there. Obviously, we're curious.

We power it up, and it actually boots Win98. We do a cursory look around, and see on the desktop that this is a local general practitioner's machine with LOADS of medical records. All unencrypted, naturally.

I try to call an insurance company of an insurance that this doctor took. I got confusion, initially. So the next day, I took it to the police station. Transferred custody of the machine, or so I thought.

Maybe 10m after that, I got a call from the security team at the insurance company, asking where the machine was and thanking me for reporting it. I told them the officer and the station I delivered it to.

Turns out, that pig stole the machine, never put it into custody, and was going to keep it for himself. I found out later that the insurance company pressed charges against the pig, and finally got it back.

That was an example of me trying to be ethical and upstanding, and seeing how cops really run their day to day business.

There are a few ffmpeg filters you can use with mpv to get this effect, though you may have to fiddle with their options to get what you want. acompressor or dynaudnorm might be what you're looking for.

https://ffmpeg.org/ffmpeg-filters.html#acompressor

https://ffmpeg.org/ffmpeg-filters.html#dynaudnorm

To use them with mpv you'd do something like `mpv --af=lavfi="[dynaudnorm=param1=value1:param2=value2:param3=value3]" ...`

(make sure the first parameter is preceded by a '=', not a ':' because reasons)
> Memorization is not going to help you solve math problems.

On the contrary, memorization is the way most people I know got through most of their math classes, at least through calculus and linear algebra. You memorize the steps by rote repetition without really learning why they work, then the test is mostly an exercise in guessing which steps and formulas you should apply to the given problem.
This is an incredibly biased article from Guardian journalists who are themselves unionized.

Describing mandatory benefits, as "rights", is an entirely ideological position, that good journalism would not pass off as fact.

Journalists using their platform to advance an ideological framework that advances their own narrow interests is a major cultural threat and deserves more attention.

Here is one example of the perverse incentives in effect:

Vox writers, who eventually unionized, spent years publishing articles arguing for laws limiting the gig economy, like this one:

"The gig economy has grown big, fast — and that’s a problem for workers" [1]

Three years after the above article was published, its agenda succeeded, and a new anti-gig-economy law, that was heavily supported by major unions, was passed in California. That law in turn forced Vox to let go of hundreds of gig economy freelancers, thus reducing competition to the full-time journalists who had, in articles like the above, used their media platform to lobby for the law:

"Vox Media to cut hundreds of freelance jobs ahead of changes in California gig economy laws" [2]

Circling back to my original point: the media being fully unionized means that it is extremely biased in its coverage of these kinds of stories.

Thanks, I saw them mentioned elsewhere here as well. How was the setup experience? Is it something I can set up if I'm not a BSD or networking expert? Do you use a wireless AP with it?
GET doesn’t typically have a body, and many services ignore it even if you include one. An API I once worked on simply truncated the body of all GET requests at the front door, because we knew we’d never use it. Less to worry about.
PG has expressed on Twitter multiple times he loathes the HN culture and always angry Californians. Probably that is why he stopped posting here as well, at least under his name.
That might be true, but I think there is a threshold called "good enough" that every parent can reach with some effort.
> That's not really different from care outside of insurance coverage that exists today, e.g., elective plastic surgery.

It is different, because in most countries where there is universal healthcare you can still cover that "private" care with a health insurance plan if you choose (e.g. BUPA or Nuffield in the UK)

And then you can do the extra electives on top of that.

So there are three tiers, rather than two.

(In the UK there are a few situations where we effectively almost have only the US two tiers; opticians, dentistry, nutrition, physiotherapy all have much less NHS provision coverage, largely because the elective stuff is so easily upsold; professionals can leave the public sector for the private money. The worst being opticians; the idea that the market can provide that more cheaply has been proved wrong.)
Not really. If that were to happen we'd be at the point of nukes anyway.
So I've taught a lot at the university level, and reading this and the original blog post they were responding to I realized that I gradually shifted in how I saw exams.

The traditional model, the one implicitly adopted in the posts, is one where the instructor presents material, maybe with some discussion or engagement with the material in the form of activities or assignments, and then evaluates understanding on an exam of some sort. In this model, the exam is a measurement. It makes sense from this standpoint that all you really need is some megaexam that measures your comprehension of the material, and if you pass it, you pass. There is something to be said for this in all sorts of areas of life.

There's another model, though, where the teacher is a sort of coach. In this paradigm, your role as instructor isn't just to present material and then measure it, but to provide incentives along the way for the student to engage with the material and process it. In this model, the exam is activity. You present a series of quizzes or exams for the student to problem solve, and you incentivize this by giving credit or not giving credit. It's the equivalent of training drills in sport. All those assignments and midterm exams are incentives for staying engaged with the material along the way, to practice.

I suppose you could say something like "well taking the final exam repeatedly could serve that role, and you can't literally give the same exam over and over again due to cheating and learning to the test, so what you'd really be doing is giving multiple exams, which is kinda like assignments" but then at that point you've redefined things so much it's a moot point. There's also little point in assigning material the student doesn't understand yet, so what you end up with is what usually is done, which is units, with assignments or interim exams that are graded along the way.

Ideally you'd have tailored material, activities, and exams that are tailored to specific students and their specific progress, but in practice at universities there's just not enough resources to do that. It's too expensive, if you include social components as part of the learning process. There are also general trends that are too hard to ignore (most students whereever you are will be in some peak of a bell curve of some sort), and so you end up with what usually happens (which is sort of the point of the author).

What a giant fucking waste of effort.

That waste is fuel, and in human history, zero people have been harmed by nuclear waste.

This obsession with nuclear waste is ridiculous. We produce less of it than any other kind of energy waste by four orders of magnitude, and it's far less radioactive than the waste that's being belched into the atmosphere to cause global warming.

This ridiculous hand-wringing is why we're shutting nuclear reactors down during a fuel shortage crisis in the middle of climate change.

We have *got* to stop pretending this is real work.
> I think the West have several escalation steps more they can get away with if they are careful.

If so, these escalation steps should be kept in reserve as much as possible, and not deployed carelessly. The Russians have not exactly been restraining themselves thus far, but they could nonetheless be doing a lot worse and being able to deter them without triggering WWIII in the process is kinda important.
> You can also note a parallel with female villains. Yeah they're bad, but you know, it's not their fault. They had such a tough life. And really are they that bad?

Popular Hollywood female villains, maybe.

My favorite female villains are Granny Goodness and Amanda Waller from DC Comics.

Granny Goodness runs an orphanage for Apokolips. On the surface, she's a sweet old lady who recruits superheroines into Darkseid's machinations. But when the going gets tough, she pulls out her super-powers to punish any orphan who goes against her will.

There's no "terrible backstory" or "not her fault" going on here. Granny Goodness is 100% loyal to the "evil new gods" of Apokolips and is incredibly competent at her role in raising new villains for the evil gods.

--------

Amanda Waller is gonna plant a bomb in your head and force you to do what she wants. Why? Cause that's what she does. She's the official government's response to counteract the rise of superheroes / metahumans (Superman / Flash / etc. etc.), and feverishly works to blackmail any prisoner into building her super team.
ISS has many components with different drag ratios and would break up unpredictably upon entering the atmosphere, making it impossible to aim reliably.

This is a big part of the difficulty in decommission planning for the ISS in general.
Sorry, have to disagree. His repeated "Putin is a brilliant strategist" is right out of right wing orthodoxy. Putin is a nascissist and a ruthless bully. His will to power is generally worshipped on the right, and mistaken for strategic brilliance, but it is not. For instance the endemic corruption in the regime is virtually absent from Mearsheimer analyses, but is critically important from a realist assessment.

Putin also sees everything in individual people terms, not structures and systems- unlike, for instance, China. This is also misunderstood on the right- the individual will to power takes precedence over structures and systems. Russia- as a system- has been weakening, not strengthening, acting only in asymmetric contexts like a jackal, a guerrilla terrorist. Mearsheimer has missed this.

Cheers.

> since we believe investing is not gambling

All investing is betting. Day-trading and forex "investing" are certainly gambling, and there is a lot of addiction among day-traders.

Stock-picking is more controversial in terms of whether to call it gambling, but if we know that nearly 100% of individual investors won't beat the market in the long-run, then it seems a lot like a casino, where the house always wins.

I have only used Apollo for GraphQL, and I found a few things about it offputting (e.g. I need a 3rd-party library to figure out what fields the client actually requested). What GraphQL server do you use? Or is Apollo + Express generally a good "default" option for basic setups?
After WWI Germany's government was overhauled and yet the allies still forced them to pay punitive reparations, so it's not exactly the same. But presumably Russia would negotiate some easing of sanctions before they withdraw; they're certainly not just going to admit defeat and withdraw unconditionally.

>If no solution is found, we're already stuck with some 22,000 cubic meters of long-lasting hazardous waste.

Not trying to be glib, but 20,000 cubic meters isn't a significant amount of space. Obviously this isn't the same as storing paper plates or pillows, but the physical size of it all is something that would fit in a small grocery store. 2,000 m^3 or 2,000,000 m^3, the size of it really isn't the attribute that's the problem.
Putin is obviously a point of failure.

But so are the hungry and scared soldiers in the field. Putin is not able to supply almost 200k soldiers, most of whom are already tens of kilometers away from the border. There will be some supply trucks coming, but if it's only 80% of what's needed rather than 100% (or better yet 120%), then soon, very soon, people on the front line will start running out of stuff that keeps them in fighting condition. And here you have so many points of failure: water, food, munitions, fuel come to mind. You run out of one of these, you stop fighting, simple as that.
