My linear algebra and multivariate calculous were not as good as I wanted them to be, so I was searching for books on the topic and those two were suggested. Then I saw that the author (Alan Macdonald) had additional material on his YouTube channel, took a peek and found them helpful.

I really enjoyed his writing style and found GA to have some very interesting abstractions but university took the best of me and I couldn't finish them. Perhaps this summer.
It is not just journalists, it is most of the people who shape culture including politicians and entertainers. That is why Twitter has a bigger multiplier effect than other social media platforms compared to their number of users. You may not consume Twitter directly, but odds are you still consume it filtered through the minds of the most powerful people in our culture.
I wouldn't describe those pop-science articles as the scientific "papers" I assumed was talked about.
Or, for the original model, 24K of the 16K of RAM, which I think gets more to the problem :)

A full 4bit graphics mode that used a 24K screenbuffer would probably have found use, even with the heavy RAM cost, though. The Spectrum's lack of graphics modes was probably important for cost from the point of view of keeping the video electronics simple and cheap, though.
I'm not sure, but from the last sentence, it seems as though they're talking about what would happen if you backed it up but didn't also back up the journal or WAL. I think the bit about SQLite being resistant to power failures assumes that the journal or WAL are present. This is supported by the next section on "Deleting a hot journal" which says "SQLite must see the journal files in order to recover from a crash or power failure."
The person who wrote that paper doesn't understand the basics of the field that he's talking about.

For example (from the blog post): "Consa gives an analogy wherein Indian mathematician Srinivasa Ramanujan has claimed that the sum of all positive integers is not infinite, but is instead -1/12. It’s wrong, it’s absurd, but renormalization has now been accepted, and is even sold as a virtue."

One when performs zeta function regularization, one gets -1/12. This isn't some mystery; it's a perfectly reasonable thing to do. Analytic continuation has been understood since the 1800s.

Edit: I read more of the linked paper. The claim that Karplus and Kroll committed "fraud" is basically libel, as can be seen by reading the complete account. The worst one can say is that people didn't publish full details of calculations due to page limitations or laziness, but this is hardly a special feature of QED. For instance, Onsager famously solved the 2-d Ising model exactly in 1944 but never provided details in print, just the final solution.
No problem. Sturdi's carriers are also really good. I took them to the bathroom to use the litter box. I'm sure you could place it on the floor though if they give you a row to yourself.

They have paid it out as a percentage of revenue over many years. They raised the offer to $5 million an episode for the 10th season (that he refused), so they only had been paying like $2 million an episode ($46 million a year) when it was on.

As far back as the 80’s there were means of distributing software without paying a retailer a commission on every sale. Shareware [1] was one such model. The software was distributed by users copying it from floppy to floppy, handing it out at user group meetings, conferences, even on the school playground. It was later included in large CD-ROM collections packaged with computer magazines.

The point is that you could distribute your software any way you wanted to without permission or license fees paid to the maker of the computer or its operating system.

That blog post author is mistaken. You can fire off async stuff outside of your handler just fine without AWS SDK v3 or top level await. Just run an async IIFE and assign it to a variable outside your handler. You can await that promise when you need it in your handler, but it kicked off running before your handler was invoked.

Humanity is like a plane at some point there is enough lift that unless somethnig traumatic happens the plane is in the air and would still be . The analogy is that people would still get interested in stuff on their own and they'd finance those things even without extorting them.

And it would be a much better distribution of capital and human resources.

This model where we extort people was valid maybe in the 1800s.

Lightening was first developed by Joseph Poon, a teenager who went on to work on Ethereum. He improved on his original idea with Plasma which was supposed to be deployed on Ethereum but was eventually abandoned for better more sophisticated scaling solutions.

The idea of lightening is literally just taking transactions off chain to reduce cost. That is it. So the solution to scaling the blockchain is not using the blockchain. I think this was invented already, it's called a (centralized) database.

The most amusing aspect of it is that Bitcoin supporters are trying to sell this as a big technological innovation when it's literally just circumventing the bloated chain.
If you want to write to an arbitrary file descriptor in Rust, you need to use unsafe code (std::os::unix::io::FromRawFd, unsafe fn from_raw_fd).

Personal takes on downvoting, or even rules, are... arbitrary? Up/downvotes cannot be controlled, it's individual opinions vs thousands of randos that each have their own reason to up/downvote. I can't think of a solution that helps rank the "best" and hides the "worst" comments, I'm used to lower-volume forums myself where replies would be in order of posting and unthreaded. An optional "upvote" system existed on the side, but I've ignored that for a long time now.

My guess is that the advertising industry has stratified and now the advertisers are rarely self-producing content. Now they just buy stock footage from content producers and add narration, text, music, done. All of these can be sourced from marketplaces and put together cheaply, a consistent process making for a steady stream of content with varying degrees of blandness.

> It is highly unlikely Putin will use tactical nukes or pre-emptively strike US/EU, no matter how grim the war looks.

I wouldn't be so sure about this. He has working hypersonics and this advantage would last very short time. Currently those hypersonics can't be even detected in time before they hit their targets and there is no real defense against them. He might just launch 100-200 of them with 100kT payload at military/strategic targets in Europe at the same time, level down parts of countries without any response outside submarines or US strategic nukes (their flight time is in minutes anywhere in Europe, insufficient time to react), and then given Europe would be written off for a century, he can try to negotiate terms with the US, assuming MAD is given if diplomacy fails and there is a proof already (destroyed Europe).

He perceives UA effectively in NATO (given heavy arm supplies) as an existential risk for Russia, so he might go all in.
The spectrum was way cheaper than a C64.

This made me laugh a little out loud as I was thinking about how poorly early mask policies were being set. It was the overconfidence of many experts that recommended against wearing masks because we had no (strong) evidence that they'd work. Only ensuring that N95 masks aren't hoarded by consumers is important.

Tell HN: People underestimate the effect of colleges in making lifelong friends

I'm learning unreal engine 5 to make vr games. I try to make stuff or find stuff online and then I put it in VR and I can look at it up close, or eventually fight it or team up with it. It's pretty hard but it's just nonstop fun.

VR is a new medium. We're in that stage now where people are sort of putting stuff from the old medium in without much consideration of what new concepts or ideas might be possible. Every UI in every game and application is terrible. Everything has to be reinvented, and can be reimagined in incredibly creative and strange ways.

Fairly often now I'll have an experience in real life and think "Someday, I'm going to put this in VR game."
If you read the history of zaplib they very much started this journey to solve their own problems.
This, absolutely. The moral failing of neoliberalism and neoliberal solutions (e.g., externality pricing) is that it requires an honest belief that a $1 delta means the same thing to everyone everywhere, which is just absurd.

Bit negative. I agree on some points (e.g. error checks on enums); other points, you simply have to learn to adapt to (initialization). The rest are (very) cosmetic preferences (overloading brackets; the compiler doesn't inform about typos).

The biggest negative for me the author overlooked is the lack of non-nullable types. The positive thing the author doesn't mention is that it's easy to write in, nor that threading is really easy.

"Mrs Kotrri said that since the letter from Zara's legal team, she had replied to 10 emails with information about her business, detailing invoices, stock, staffing and articles written about it."

Mrs Kotrri seems like a nice lady, but this was probably a mistake. She had no requirement to tell them anything, and this was never going to make their lawyers back down. The lawyers will just pull out any detail that might help them in their future case, and ignore any and all details that don't.

I expect it probably would have been best to just send back a letter from a lawyer-for-hire denying any hint of infringement, and then shut off communication.

I wouldn’t consider the rocketry code itself a good argument. The model rocketry code, frankly, is biased hard against any kind of liquid (especially non-hybrid) rocket engines, so there’s not even really a way he could follow it with a liquid in any reasonable way.

Very good article, but have few shortcomings.

1. Only first generations of "Soyuz" used H2O2 propellant, because it have very limited time before use (for "Soyuz", guaranteed 6 months), and because it have relatively high melting temperature.

First chose H2O2, because "Soyuz" planned as independent ship, to fly relatively short missions around Moon (it is near impossible to withstand even 6 months in so small volume).

When "Soyuz" primary role become companion ship for space station, it switched to hydrazine type propellant.

2. In pressure fed engines used almost all possible propellants and oxidizers.
This is not error just clarification.

3. Exists three-propellant engines. For example, exists soviet engine for "spiral" system, which used kerosene+LOX+LH. First it run on mostly kerosene+LOX, with small percent of LH, than switched to pure LOX+LH (sure, LOX share also other).

4. Exists simpler bipropellant engines than mentioned, unfortunately with worse efficiency. - First Britain satellite flown on H2O2+RP1 Black Arrow rocket.

Absolutely. Java Lambdas are often particularly bad in this respect; all the nice abstractions and class hierarchies seem to go out the window as soon as one “implements RequestHandler”.

Has anyone ever tried to capture outside air and mix it in the rocket exhaust? The reason would that more mass expelled at lower velocity can produce the same thrust with less energy.

I think you meant to say 'C Experience'.

No C++ coder I know (at least the true C++ coders, e.g. ones who have abandoned the 'Simplicity of C' mantra), find nothing of use in go besides a draconian single truth model of 'the best way to do things' similar to Python.

That is really opposite of the C++ experience, where you have millions of different patterns, techniques, and pitfalls at every corner. Those who enjoy this, are definitely not go enthusiasts.

Now I'm not saying ones better than the other, but I really doubt C++ core find Go attractive. Go was invented on the premise that 'We hate C++' or something to that regard.
