There's this concept in game theory that it's sometimes worth it to hurt yourself in order to hurt an uncooperative player. If you are always thinking "how do I minimize harm to myself" you get salamied to death. Same as in a poker game, you can't fold every time someone raises big, just because you don't know which times he actually has good cards. If you do he ends up with all your chips.

Other thing is about MAD. At some point this hypothesis needs to be tested. Yes, as a child of the cold war I am well aware of the stories about there being a warhead with my city's name in Cyrillic painted on it, and the same with every city in Russia, in English. We're conditioned to think that as soon as the missiles are launched, countermissiles will also launch, and then we're all doomed, planet is handed over to cockroaches.

I'm not sure it's true. For one, it's actually happened that missiles looked like they were in the air, and a Soviet guy decided it was best not to send missiles back, and we're all still here. I also get the feeling, from introspecting, that a lot of people would not actually press the button if they saw that radar picture. Would you make the world unlivable for little Russian kids? I'm not sure I would, and though I don't know how many people are making these decisions, my guess is it would be really freaking hard.

Which bring me to my next point, and this will cause some consternation. How bad is it if a nuke or two goes off? We care that the whole world isn't turned to dust, but if we get another Hiroshima somewhere, apart from the enormous shock it would cause, it might stand a reasonable chance of ending whatever conflict it happened in, just like the actual two nuclear attacks in Japan. Is that totally crazy, or is MAD literally coded into the machines now? Maybe someone can enlighten me.

Pardon my ignorance, is the spectrum of a graph something more than simply the set of it's eigenvalues?
It would't be the first time... ISS spun out of control before and the Russian jets couldn't be started because the Russian control centre was out for the weekend.
Not only that, but the reports of a huge chunk of the Russian military moving towards the border is pretty much all the info you needed to know. I doubt the Russians can afford to mobilize their military to have it pull back as a bluff.
I think the author is mostly correct, however has one big blind spot.

US policy towards Ukraine is not incorrect, it’s working as designed from the start. They knew how Russia would react, they were just willing to throw them under the bus so they can force Russia’s hand.
Sure, but that’s not universal. Certainly the best approach is to offer remote to those who prefer that. But for those who live close enough to the office, and are positive to agnostic about going in, maybe a half day is a good way to feel not trapped in the office, and to beat the traffic.
It used to be possible to flash a new OS on Samsung devices that are bought directly from Samsung, don't know if that's still the case
MAD was only really feasible when just three countries had nukes. It was abandoned a while back. Russia chose to pursue nuclear supremacy over conventional defense. They have the biggest arsenal, as well as super-nuclear and super-sonic ICBMs to deliver them. Russia is the only country I know that thinks it might actually be able to win a nuclear war.
LA also does spend money just booking rooms at for profit hotels for homeless people vs constructing shelters at cost too, so not everything they are doing is totally productive and efficient.
This really can't be taken seriously if they don't even bother addressing the BANAL-52 or RmYN02 sequences which very nearly have a functioning FCS:

https://ibb.co/T1YtShy

There is a QTQTN deletion in circulating SARS-CoV-2 at the flanking region at 675-679 which has been observed in circulating human strains at the level of a few percent along with mouse-adapted strains. RmYN02 is closer in nucleotide sequences to those variants of SARS-CoV-2 than to ancestral (the SARS-CoV-2 variants carrying that deletion not show in that figure).

If there are variants of RmYNO2 which retain the QTQT sequence at 675-679 then that virus would be one amino acid insertion away from a functioning QTQTNSPRAAR FCS sequence. Then flipping another amino acid would give the SARS-CoV-2 sequence. The relative probably would be discovered with a higher level of surveillance and sequencing of sarbecoviruses in wildlife.

And the rest of the argument in this paper is some weird genetic numerology.
This is sarcasm, right? (the part about Iraq and Afghanistan)

The abstraction hasn’t hindered me much and I work on a monolith.

One problem I have faced is when the amount of database queries on a page explodes it becomes hard to optimize without caching. I would prefer to avoid caching but that doesn’t appear to be the rails way (and for obvious reasons).

Also, at a company with a Rails app you do sometimes get other sources and processes polluting your Rails app. And when that happens you can’t utilize the efficiencies that rails provides.

This is a helpful comment, thank you. Prioritizing sociological factors in the design of educational systems seems common, but balancing the differences within an educational population with policy requirements makes it so that only some students get the resources they need.

In my life, I have been lucky to have a sticky brain, which has gotten me through for a long time. The problem is that I cannot pinpoint any significant moment in my education where some tactic or teaching influenced the way I study. I remember lectures about Cornell notes and other strategies, but I never needed them, and then once educational challenges became too great for me to handle with my habits, that's when I REALLY needed them. I've taken the project to heart and prioritize my exploration and implementation of better learning strategies. It took me years.

It's like, the world of knowledge is a huge cavern, and I adjusted and mastered navigating by touch. Once I reached a larger opening, the cave was much too large to navigate in the same way, and I found myself stuck many times. If only I had realized that by opening my eyes I would have noticed the torches lining the walls above my head. I think I would have been able to contribute much more in the time I've been around so far.

I don't feel sorry for myself. I live a good life. I have taken responsibility for my own advancement and learning. I empathize with others who struggle with what I've struggled (and continue to contend with) in terms of learning methodology. I hope that throwing my little anecdote into the mix counts as a drop in the bucket.

I bought Radeon RX 5700 XT in 2019, roughly a month after it's release. It didn't work for me with the latest kernel at the time. I was so disappointed, I wanted to give my money to AMD, but had to go with Nvidia instead. So Nvidia's driver, hated as it is, does have advantages.

Very exciting. As this works on Fuchsia, a capabilities-based OS with a security-first design goal, is there any writeup on the security architecture for this project?

Is it correct to say that a convergent desktop environment exposes a large surface area via monolithic access to the underlying OS? It seems that the desktop environment is one of the hardest things to build securely, if embarking on such a journey.

Also, somewhat related: In light of forthcoming capabilities-based hardware (see: ARM Morello), is it a bit hasty to embark on a security-first rewrite of the entrenched Von Neumann / Harvard basis for incumbent OS environments?
It did, and a decade later it launched an all out attack on the whole of Ukraine to "protect" the newly recognized DNR/LNR. A paper thin excuse, something a HOIIV player or a deranged dictator would come up with.

With no strong opposition to that, drunk on success, ~~Hitler~~ Putin can go further.
Or conversely, when you have a flappy monitoring system that constantly complains about non-problems and half-problems, it gets very hard to notice when an actually serious alert is firing.

I think MAD is only half the equation. Even if Putin didn't possess a single nuke, (EDIT:) Nato might very well have stood by watching today, as the conventional force deployed by Putin is pretty significant in itself.

Similarly, had NATO deployed 500k soldiers fully armed with modern weaponry in Poland, Lithuania and Rumania as Putin was building up his forces, and added a warning that Ukraine would be granted instant membership to NATO if he didn't pull back from the border, he probably would have pulled back from the border.

But NATO doesn't have those forces, primarily because most European countries have neglected their armed forces over the past 30 years. In reality, a conventional confrontation with Putin would be very difficult. Eventually NATO might win, but it would take years.

Given the fact that the EU alone has around 10x the GDP of Russia, the EU could relatively easily have had an army that is 2x to 5x more powerful than Russia's, even without assistance from the Anglosphere (which would have left the Anglosphere able to focus on China).

One may hope that the EU learns from this. Otherwise, I fear the result of today's events will be a massive level of nuclear proliferation. If NATO cannot even keep their neighbours safe, what confidence can more remote countries have that they will be protected if attacked by a nuclear power, such as Russia or China?

And once virtually every country has nukes, they WILL see use.
Ultimately, you have to trust some photographer or organisation.

The camera sensor is not a trusted input. Nothing can prevent somebody pointing their camera at a high resolution screen displaying a manipulated image. Or a staged scene. No image signing mechanism can prevent this kind of attack.

There are manipulation detection techniques, but they are imperfect. And even if you verify the image is an unmodified camera original, you still have to analyse the context surrounding the image (what is portrayed in the image, does it line up with other reports, who is the photographer etc.) to determine if it is actually a true.

It is trivial to digitally sign text, but a signature on a string doesn't mean that string is telling the truth. It just means someone signed it.

Also when you were 8, you didnt have about 1 million developers making 500k per year trying to extract(and sell) every single bit of your attention in any possible way. From roblox to netflix to tiktok to supercell.

It took us like 300 years to learn how to teach math, and we are still improving, we are getting new tools every day, just look at https://www.youtube.com/3blue1brown can you imagine how many people he himself has reached and inspired? People that previously thought: "math is not for me".

No, it's not, quite. I don't know if I can describe the difference without getting into politics which is apparently as unwelcome here as humour, but here goes. I am trying to be apolitical here.

Baghdad Bob and Sean Spicer were really quite different.

OK so you are partly right on two fronts.

One, there was a Baghdad Bob moment right at the beginning, the whole "largest crowd ever PERIOD" rant, but even the presentation and the sentiment of that were rather different. It had no humour, it was an angry, hectoring, nasty, shouted attempt to bully and control.

Two, he failed at it in spectacular fashion, which did lead to him being car-crash television in kind of the same way BB was, except he'd so severely soured his relationship with the press corps that you were watching a man slowly shrinking, rather than a man in control of the limelight.

But Spicer also was just plain bad at his job, ignorant of history, incompetent, indifferent or unkind on screen to the people he spoke to, had terrible presentation, no theatrics, no presence, and he told humdrum, lazy, formulaic lies among his charmless distribution of the day-to-day humdrum stuff. Not comparable to BB. No one believed in him, but the press corps went there expecting to -- needing to -- be told the truth.

Apolitically: a really bad press secretary, in short. Out of his depth.

Trump's own press conferences were much more like Baghdad Bob in tone and approach; Trump inflated the truth, told huge, flowery, dramatic lies, timed press conferences to distract, and used one ridiculous hoax claim to distract from the fallout from another. Theatrics, performance. A weird amount of car-crash TV control from sheer, unprepared brinksmanship and BS (in the specific sense of indifference to the distinction between truth and lies). Like with Baghdad Bob, the truth was never being approached; it's not what the Trump press conferences were even for.

I often felt a little sorry for Sarah Huckabee-Sanders, who to be clear told the same sort of lies as Spicer, but at least you could tell it made her uncomfortable to do it, and you could tell she cared about the press corps as people. She especially hated clearing up after a Trump press conference.

In the interest of shameless self promotion :), my own experimentations are :

https://github.com/auxym/nim-on-samd21

And I've used and contributed to picostdlib (https://github.com/beef331/picostdlib), the rp2040 support library.

All just as a hobby, but it's interesting to learn that some companies are actually looking into Nim for firmware! Embedded seems like such a slow moving industry. I believe the author of Nesper and Nephyr also developed them for professional work.
I'm very skeptical of the following question, but I found from a reputable reporter on Twitter, and seems like at least not an obvious fake website. But I don't see how this can be true... Anyone smarter than me care to alleviate the following concerns:

I'm reading Eric Schlosser's Command and Control right now (1). Housing becomes quite elastic in the face of bombing. Fred Iklé actually developed a formula based on WW2 Germany for RAND:

Fully compensating increase in housing density = (P1 - F) / (H2) - (P1 / H1)

* P1 = Population of city before destruction

* P2 = Population of city after destruction

* H1 = Housing units before destruction

* H2 = Housing units after destruction

* F = Fatalities

The tipping point seemed to be reached when about 70% of a city's homes were destroyed. That's when people began to leave en masse and seek shelter in the countryside.

10% of what? Semiconductors? Sure, that's easy, and already done; US semiconductors are 13% of the global market, so presumably they're about that share of the domestic market and probably more.

The components necessary to manufacture them? Much more difficult. And remember, any encumbrance you put on Intel provides a competitive advantage for TSMC.

The other issue is if you require 10% of semiconductors to be made in the US, and 10% of their components likewise, that only leaves you with 1% of the semiconductor capacity you need if you really need to become autarkic. And that's only considering first order dependencies; what about the components needed for the components you need?

Now, even ignoring that, consider if Intel has to make 10% of its chips using machines and components made in America. Say ASML makes the best photolithography machines in the world. Some other foreign company makes the best of another machine in the world. And so on. So Intel has to manufacture 10% of its chips using subpar equipment. Who's going to buy those chips? If electronics need better chips, can you replace them with these in a pinch?

You either need to fully commit, or else it's pointless to begin with.
> Perhaps I was wrong to expect mention of explicit discsussion of spectral graph theory?

I mean, this is a link to a pdf titled "chapter 3" buried deep in the directories of someone's academic homepage. There's no context about who the author is (is it a student project from a course? Part of a dissertation? notes for a draft of a book?), except that I think I can extract their name from the URL. It's pretty hard to tell, thus, who the desired audience is or what the aim of it is.

So whether one should expect one thing or another from this random pdf... I mean, without knowing more, what is there to reasonably expect?

For instance (and I can imagine this because I've taught an undergraduate course on graph theory, among other undergrad math courses), if these are notes from a course, then the instructor may have some good, context specific reasons for focusing on some topics while not going into details on others. But, as I said above, it's really impossible to know because this has just been plunked on HN with no context, as if that is somehow valuable.
Yeah, the Pi would definitely be a better choice for this but even the Pi Zero would be 2x the price of the ESP32CAM I'm using (which in the country I live isn't as cheap as in the US).

Mostly, yes, unfortunately. Avocado oil is also quite highly processed but is the lesser among the evils. Extra virgin olive oil and unprocessed coconut oil are good. I've come to understand that reducing fat intake via cooking oils but increasing it via healthier raw/unprocessed fats are better (olive oil, dietary fats from fish, eggs, etc).

Also note that, oils can oxidize fairly easily. I still don't know how to procure oils from supermarkets that I'm sure are not already oxidized. Then comes the matter of storing it in ways to prevent oils from oxidizing.
