We don't really have to guess: as jet engines became more fuel-efficient, inflation-adjusted prices for air tickets dropped. And as oil prices fluctuate, so do ticket prices. There…

But are you willing to pay 10-20% more for that joy? I personally would rather pay less money to fly, not get to see out the window, and spend those dollars on, say, a fancier meal…

Yes, exactly this -- it's a fast and convenient way for my code to just write the pixels into a spot in RAM (the CPU's RAM, not VRAM) and have those pixels end up on screen. On mod…

I went through this a few months ago in Rust. I wrote all the code by hand, no LLMs. Then I went ahead and added a small "game" on top, plus some special effects like pixelization …

That's technically correct but consider the following: You're implementing quicksort. The actual algorithm is a conceptual piece of math. You write the code. But sometimes the code…

Hey! Thank you for posting. This a great project and an excellent illustration of progress in technology: commodity hardware and open source software got good enough that you could…

What do you mean not serious? He’s developing visual aids to teach students and to accompany his mathematical research papers. Also, not in this post, he’s been actively using LLMs…

Thank you and yes, I agree! It's neat to use the binomial theorem to see this, because that's the tool the article uses for the main trick/insight it's explaining.

I love complex analysis, and that's the branch of calculus that is most associated with number theory. For example, it was critical in the original proof of the prime number theore…

I've had a similar experience with Apple Store employees many, many times: I walk in and vaguely describe what I want, and they steer me to the cheapest item they sell that could p…

Maybe you mean it's a crime to professionally provide advice of this nature without a license? It is generally not a crime to casually provide advice of this nature without a licen…

As you say, "the fundamental theorem of algebra relies on complex numbers" gets to the heart of the view that complex numbers are the algebraic closure of R. But also, the most sli…

You can think of it as returning an equivalence class if you like. Then it's single-valued. More explicitly, it returns an equivalence class whose members are complex numbers that …

One technical point about resonance: the fourth-power law only applies when the driving frequency (i.e., the frequency of visible light) is far below the resonant frequency (which …

For those who don’t know: the film City of God is based on this, and it’s a great movie. One of my all-time favorites. The directing, acting photography and storytelling are all ve…

> The money goes to the investors who sell. The investors who sell are wealthier by amount $X because now they have fewer shares and more dollars. The investors who don't sell are …

Three things: 1. From the perspective of shareholders, and for the moment ignoring taxes, buybacks and dividends are exactly economically equivalent. If a dividend happens, you get…

This is great! Lovely to see a clean new codebase implementing quantum chemistry algorithms like Hartree-Fock. I remember using Molpro at my fist job. Venerable and comprehensive i…

I actually visited that link, and the answer seems to be "If you've seen my socials lately, you might have seen me talking about Ralph and wondering what Ralph is. Ralph is a techn…

Thanks dang, you’re right, I apologize and will keep this in mind in the future.

This is so poorly written. What is "Ralph"? What is its purpose? How does it work? A single sentence at the top would help. The writer imagines that the reader cares enough to have…

Many tools offer offline file browsing and full text search. Anything from midnight commander to Alfred to ripgrep. I think the valuable and difficult thing is high quality, fast, …

Won’t this only work when connected to the internet? So I can’t use it on a flight. Or if I work in finance, or healthcare, or law, or government, or a hardware design company, I d…

I don't think it's that silly. BusyBox packages a bunch of utilities in a single binary. It amortizes fixed costs: a single binary takes less space than 30 binaries that each do on…

Thanks, I’ll take a look. I love obsidian for the same basic reason you do: it’s just a bunch of text files, so I can use terminal tools and write programs to do stuff with them. S…
