This is wonderful! I can't help but to be reminded of the book (and excellent movie) The Hunt For Red October, where a [edit] "caterpillar" drive on The Red October sounds like seismic activity, but when sped up is clearly mechanical. This is not he same, I know, but it has the same vibe.

Whoever thought to do this... Kudos to you! (And I... was never here...)

Russia’s ruling party suggests nationalization of foreign businesses
I think these projects are less about making money directly. Mostly these projects are only profitable/feasible with the help of lots of government funding. I assume they have secured some of that.

The reason that the British government is interested in subsidizing nuclear is that they want to maintain their nuclear capability and want to stay credible as a nuclear power. That, and the French are also investing. Either way, that makes it interesting for the likes of Rolls Royce to get involved. There's government money to be had. And maybe Rolls Royce stumbles on something useful; like a cost reduction that makes nuclear a bit less expensive. I wouldn't count on that happening quickly though or in any amounts that really matter.
Solar + big batteries can provide electricity when the grid is down.

If you need a backup plan, then a regular gas station and perhaps hybrid emergency fire trucks seems to make more sense. Since all the infrastructure is available for that right now.

It's a worthwhile specialization, but I have no idea how broken your recruiting pipeline would have to be to consider a layout designer for a "EE generalist who lays out his own circuit boards" sort of position. The typical layout designer does not have a BSEE or a resume that would indicate proficiency at circuit design - let alone project and customer management skills - it has historically tended to be a technician or draftsman level career path.

A previous version of the post used true/false, but I think color is easier to understand after revision (e.g. "left always points to an element corresponding to true" -> "left always points to a green element").
This article implies the opposite of the claims in this study.

https://www.bulletproof.com/diet/healthy-eating/good-fats/

"Saturated fat got some negative press back in the 1960s, when a scientist named Ancel Keys published research that claimed it caused heart disease. You’re probably familiar with the theory — that the saturated fat in butter, red meat, and egg yolks drives up cholesterol, which builds up in the arteries, blocking the flow of blood to the heart. The study was later debunked — it turned out Keys had manipulated the research to demonize fat. Later studies showed that saturated fat doesn’t raise levels of bad cholesterol (LDL) in the body.[15][16] Yet saturated fat is still shaking off its reputation as an artery-clogger.

The fact is, saturated fat is the most stable fat that there is. A stable fat is the least likely to be damaged by oxygen (aka oxidized). Oxidized fats accelerate aging, cause inflammation in the body, and make weaker cell membranes."

I open up a Python shell window probably 20 times a day to do simple maths…
I'm really wary of this. House wiring would be more useful than Shakespeare. That's not to knock house wiring, or statistics. I'd love to know more about both.

But don't deny yourself an understanding of the meaning of limits. Almost all mathematics before calculus leaves you with a misimpression that neat formulas exist to solve problems. In reality, you've learned to draw straight lines with a ruler, and maybe a few curves with a compass. Before Calculus, you might actually believe that numbers that can be expressed as the ratio of two integers are typical, and that numbers like pi and the square root of two are "irrational" rarities (and until calculus, you probably don't know about Euler's constant unless it was introduced in precalc as another one of those odd and rare numbers).

Look out at nature, where are the triangles, rectangles, and circles? Maybe a wasp nest? Nah, not really. Try to draw a cloud, a tree, a tiger, or a human face. How useful is that straight line or compass? How useful is a line at all, other than to hint at something you can't actually draw, maybe by implying it exists as an ever vanishing limit from above and below? Math required calculus the instant humans decided to describe the world as it is, rather than by the limits of what we impose on it.

Also - in stats, how do you know what the area is under the probability density function?
I... put politely, don't understand how manufacturers can make that claim, it depends on exogenous factors. That said, you're right, the newest turbines are impressive structures and more consistent at their job.

Also that said, andy_ppp is right, or will be soon. If you want to make a dent in our fossil fuel needs on a cold windless day, you'll have giant globs of excess energy on warm windy days, that is simply orders of magnitude more than any practically-costed battery can store. At that point, who cares if electrolysis is only 30% efficient?
Why hypothetical? The famously least regulated grid of all is heading straight into battery based storage without a subsidy in sight. Nothing hypothetical about it.

> "Battery storage. In the next two years, power plant developers and operators expect to add 10 GW of battery storage capacity; more than 60% of this capacity will be paired with solar facilities. In 2021, 3.1 GW of battery storage capacity was added in the United States, a 200% increase. Declining costs for battery storage applications, along with favorable economics when deployed with renewable energy (predominantly wind and solar PV), have driven the expansion of battery storage."

Fair enough. In that case the policy should not be changed because the crimes involved are low-value and should not be a target of scarce (by the department's estimation) police resources, particularly with respect to the crimes being committed by the stores themselves.
Russia’s ruling party has come up with the idea of nationalizing the production of companies announcing their departure from the Russian market during the military offensive in Ukraine.

Since the launch of the military operation, dozens of international enterprises have revealed their intention to cease operations in Russia, and the list is constantly growing. The secretary of United Russia’s general council, Andrey Turchak, called these actions “stabs in the back,” and warned of “tough retaliatory measures.”

“United Russia proposes to nationalize the production of those companies which announce their departure and the closure of production in Russia during a special operation in Ukraine. This is an extreme measure, but we will not tolerate stabs in the back, and we will protect our people,” Turchak said in a statement.

He called the companies’ decision to leave Russia “a premeditated bankruptcy,” “a purely political decision,” and part of a “sanction war against Russia.” Therefore, he argued, the main task of the Russian authorities is to “to preserve jobs” and not let the economy “be destroyed from within.”

“This is a real war, and not against Russia as a whole, but against citizens. We will not look at it indifferently. We will take tough retaliatory measures, acting in accordance with the laws of war,” Turchak said.
I had not caught that bit before, either:

> The main incident occurred on 14 November 2004, but several days earlier, radar operators on the USS Princeton were detecting UAPs appearing on radar at about 80,000+ feet altitude to the north of CSG11 in the vicinity of Santa Catalina and San Clemente Islands. Senior Chief Kevin Day informed us that the Ballistic Missile Defense (BMD) radar systems had detected the UAPs in low Earth orbit before they dropped down to 80,000 feet. The objects would arrive in groups of 10 to 20 and subsequently drop down to 28,000 feet with a several hundred foot variation, and track south at a speed of about 100 knots.
what about google then ;)
At least with the CAs we've worked with, the EV certs are required to either be issued in a CA-provided hardware token or you have to demonstrate positively that you have the key in an Hardware Security Module. That's the piece of validation that's really meaningful to me at the EV layer for code signing, and I think it's most of the reason that those are afforded better reputation as well.
If by "responsive layout" one means adapting to the size of the browser window, and not specifically adapting to mobile screens, then it was fairly common in 2009. And even earlier - we just did it with tables in late 90s and early 00s.

It is also true that the vast majority of web pages done in Flash did not do it.

Nope, I have essentially zero spatial abilities. I get left and right confused constantly, and frequently write letters backwards(In addition to writing totally unrelated letters if I don't stop and think about each one)

I also can't really rotate something. When I spent a few hours with a driving simulator game to see if it was at all possible one big issue I had was not being able to figure out which side was the right side of the road, relative to the new perspective after a turn. So I turned straight into traffic more than once.
Agreed.Though I'd say that UK has uniquely(amongst EU at least) been proven as a good supporter and ally with EE through NATO for military purposes.Indeed, if only 50 visas have been given that's a pretty low number, but I'd be curious to know if rejections for visas are because of immigration policies[which I respect,from both a democratic prism and from my personal ideology] or security concerns.
Seems like it was a legacy mod_perl code base that was difficult to maintain. https://web.archive.org/web/20220225082909/http://ars.userfr...
That is still very technical work however - and I bet you are decent at scripting in a language or two. Still plenty to test with that (theoretically).
I would have no problem with this as a 45min screen after having talking with a hiring manager. I’m going to invest that time anyway and it’s nicer to not have to “do it live”. There does need to be humans for the later rounds though - because I’m assessing the company as much as they’re assessing me!

What makes you think the Federal Reserve would just give all the data to, say, the FBI without a warrant?

You talking about "the government" as a unified entity seems odd to me here. The various bank regulators (FDIC, OCC, and yes, that same Federal Reserve) already have access to huge data flows. If they are already misusing it, it doesn't sound like this would be worse. And if they aren't, then I'm not seeing why that lack of misuse would change.

I'm pretty dependent on the ability to deduplicate files in place without massive overhead. The built in defrag on BTRFS is unfortunate but I think you can defragment and re-deduplicate.

I don't know, I'm just hoping for a filesystem that can get these features right to come along...

If we're talking online, WolframAlpha is amazing. Used to use it all the time. Now I use Emacs Calc, since it's built right into Emacs (a keybind away), and it's pretty nice and featureful.
In a former life I ran a web site with a co-founder. We needed to upgrade our main system (we only had 2), and had mirrored RAID1 hard drives, some backup but not great. We tested the new system, it appeared to work fine, so the plan was to take it to the colo, rsync the old system to the new one, make sure everything ran okay, then bring the old system home.

We did the rsync, started the new system, it seemed to be working okay, but then we started seeing some weird errors. After some investigation, it looked like the rsync didn't work right. We were tired, it was getting late, so we decided to put one of the original mirrors in the new system since we knew it worked.

Started up the new system with the old mirror, it ran for a while, then started acted weird too. At that point we only had 1 mirror left, were beat, and decided to pack the old and new system up and bring it all back to the office (my co-founder's house!) and figure out what was going on. We couldn't afford to lose the last mirror.

After making another mirror in the old system, we started testing the new system. It seemed to work fine with 1 disk in either bay (it had 2). But when we put them in together and started doing I/O from A to B, it corrupted drive A. We weren't even writing to drive A!

For the next test, I put both drives on 1 IDE controller instead of each on its own controller. (Motherboards had 2 IDE controllers, each supported 2 drives). That worked fine.

It turns out there was a defect on the MB and if both IDE ports were active, it got confused and sent data to the wrong drive. We needed the CPU upgrade so ended up running both drives on 1 IDE port and it worked fine until we replaced it a year later.

But we learned a valuable lesson: never ever use your production data when doing any kind of upgrade. Make copies, trash them, but don't use the originals. I think that lesson applies to the idea of doing an inplace conversion from NTFS to Btrfs, even if it says it keeps a backup. Do yourself a favor and copy the whole drive first, then mess around with the copy.
We've been working on a condensed version, it has been almost complete (all 440+ glyphs) since last year but it has a few wrinkles that need to be ironed out. This will also enable a Width ('wdth') axis on variable fonts so if your editor supports, can smoothly go from Regular ---> Condensed ---> Compressed versions.

There is also a complete Extended version but it has many issues, we won't be releasing that anytime soon.

If by worse electric trains you mean electric trains that can solve the last mile problem all in one mode of transit, then yes.

Visual a bus that picks you up at its regular stops, but when it enters the highway of uses a long stretch of overhead wire to use nil battery.

You get the benefits of scale and flexibility of a bus, but at a reduced cost than train infrastructure while still moving many, many more people than a car.
Are you talking about non-US banks that have dollar-denominated accounts? Because US banks are insured by the same federal government, making the credit/liquidity risk the same.
I recommend https://insect.sh (you can install it through NPM to use it locally). Does simple maths well, does functions, does units, does conversions... pretty cool shell calculator.
I’m slightly confused on why that would be useful within the rsync.net context. Is bouncing traffic a new intended use case?
Sounds like you are in one of the camps.

If you are going to call out "the science" and speak disparagingly, you'd better provide references. Preferably comprehensive analysis, and not a few cherry picked studies. Otherwise you are just adding to the noise.
Looks like flightradar24 to me.
You are right. There's a paper analyzing the situation "Fantasy Counterfactual: A Nuclear-Armed Ukraine" [1] and they identified numerous barriers.

* The nukes were actually Soviet, and when the USSR dissolved they came under the control of Russia in practice. They were physically in Ukraine but Ukraine did not have custody of the warheads, nor did they have access to the command systems and codes to fire them. (Kazakhstan and Belarus were in the same situation.)

* Russia would almost certainly not have let them take the nukes! The most likely result of a Ukrainian seizure, or attempt at seizure, or basically anything but agreeing to hand them over in the early 90s, would have been Russia invading. They would probably have had European and American blessing to do so; the US was actively helping Russia track down and collect all their nukes and was, understandably, quite alarmed at the possibility of proliferation due to the USSR's break-up.

* Even if Ukraine somehow managed to seize the nukes, not get invaded, not become an international pariah, and override the Soviet command systems, they still would not have been able to maintain them. Nuclear weapons are an active system, not something you can just store in a warehouse somewhere should you need them one day. The nuclear materials decay and need to be cycled out with reprocessed materials on a regular schedule. Equipment needs maintenance, especially the rockets. None of the nukes or delivery systems would have been working within a few years. Ukraine did not have the facilities or resources to maintain them, nor was developing them a particularly realistic possibility. (They'd basically need cooperation from another nuclear power, or to do their version of a Manhattan project.)

Ask HN: Product Managers, what tools do you use to track non-dev focused work?
My team uses GitLab for repos + project management, but I find myself unsatisfied with it for larger product initiatives + vision, i.e. sketching emerging ideas or things like design initiatives, documentation, GTM roadmap, etc.

What are your go-to tools for tracking and managing the non-dev side of your work?

I've used an amalgam of tools in the past (Sheets + Asana + Confluence + Trello) but haven't found anything that makes me go "Aha!"
Hi HN! I frequently find myself needing to label small batches of images with class labels as well as bounding boxes and masks. Last year, I developed a Python library to do that sort of thing relatively quickly using a command line application that launched a web interface. But I often want to do it right inside the Jupyter instance that I'm already in. So I recently developed the functionality into a Jupyter Widget. To make it easy to try out, I've made a short Colab notebook that shows what it can do.
The capitalist mode of production relies on extracting the surplus value of the worker. Simply put, people have jobs because the company makes more money with the worker than without the worker. I have never heard any economist, heterodox or not, claim otherwise.

Deep learning also messed up the definition of tensor, and so they are the ones who should be careful with picking names.

(That you can represent a tensor by a multidimensional array does not mean that a tensor is a multidimensional array).

"the progenitor of known SARS-CoV-2 sequences likely contained three mutations relative to the market viruses that made it more similar to SARS-CoV-2’s bat coronavirus relatives."

So sort of. The virus existed somewhere before the versions sampled in the seafood market, yes. It's possible that it existed in the seafood market but was not sampled there.

There's no way to know where it first existed in humans without more information and the deletion of this early data is definitely suspicious.
Why can't that stuff just remain diesel? We can synthesize it, no problem.
My personal pet peeve with Flash websites was that all the text was usually non-selectable (and thus non-copyable) except for widgets such as text boxes. So e.g. in case of the menu, you couldn't copy the name of the dish to look it up. In other contexts, it could be a much bigger annoyance.
Your margins care, since those are a factor of installation cost, marginal cost and energy lost due to round trip efficiency.

That 70% loss defines the lowest possible price difference between buy cheap power and sell expensive. Therefore any other smart consumer or storage has that margin to work against, to compete you out of the market. This is why batteries can work, in some cases. But it is a pure inefficiency that will find a minimum equilibrium.
I do think you're right that at a certain size a company should be able to efficiently employ humans to solve human problems within a system. In practice, this turns out nightmarish. I think that's where governmental institutions can play a role in setting expectations for people interacting with large companies, especially ones that provide critical infrastructure (which admittedly, is a growing amount). We can't just declare them all public utilities, so in a way I think this sort of problem demonstrates a need for evolution in the way we govern people and corporations.
And in a wartime era in a world that is de-globalizing, how does that strategy play out for a country?
Definitely. Given how much smaller the Internet was at the time, a lot of the people actually making the Internet -- Linux developers, webmasters, hardware designers, network protocol authors, etc. -- were packed into that one amazing forum and debating what to do next. It was amazing in its heyday.
