> We don't recommend oh-my-fish for various reasons Care to elaborate a bit on those? Or is it the kind of thing that's impolite to discuss?

If b is negative, define c = -b, and use the linked result to show that a^2 - b^2 = a^2 - (-c)^2 = a^2 - c^2 = (a + c)(a - c) = (a + b)(a - b)

> Then you've just skipped the case when a^2 - b^2 is negative. Not really. If b > a, then swap them to conclude that b^2 - a^2 = (b + a)(b - a), which is what the visual proof dem…

Steve Jobs would have agreed with you at one point. I'm not sure what changed his mind (or if he ever even really did), but he also thought that aside from the native apps that cam…

Huh, is this what Nix users mean by “impure”? If so, then it makes so much more sense to me now.

> Anyone could just change username/organization and break thousands/millions of build. GitHub redirects you to the new name in the event of a rename and you look up the old one.

> even package managers like pip This reminds me of a blog post [1] I read before. Pertinent quote: > Unbeknownst to me, even with --dry-run pip will execute arbitrary code found i…

I was going to say that the title reminded me of these notes I skimmed through ages ago called “Street-fighting mathematics” [1]. Sure enough, the end of the article indicates [1] …

Interesting problems! It’s not hard to intuit the truth values of the conjectures in the first two questions. I don’t have proofs, though. No idea about the third one.

David Williams’ Probability with Martingales is a personal favourite. And I’m not the only one.

Almost everything here is an unmitigated disaster. However, > the secret exemption of Alameda from certain aspects of FTX.com’s auto-liquidation protocol — barring the part where t…

Same. My requirements are very basic, so the switch to colima was basically seamless. I also appreciated being able to avoid Docker Desktop constantly trying to update itself (whic…

> just banging out definitions and theorems This is pretty standard for graduate-level math texts, though. That might say something about their intended audience.

Judging from the TOC, everything in Part I of Boyd and Vandenberghe appears in some form in the monograph, so I don't think that's it.

I'm really impressed at how this article uses exactly the right amount of detail to illustrate the points it's trying to make. I've read too many that either have too much or (more…

I think you can just do `tmux new -A`. IIRC this is equivalent to `tmux attach || tmux`.

Prefixing `arch -arm64` is pretty solid advice still, I think. It's really easy to inadvertently run your terminal in Rosetta, and not notice that you're running a non-native versi…

Note that the argument you've called ridiculous is a response to someone who does not want a > closed source, walled garden product from a company with business practices I don't l…

The claims I made are not solely about China: they're true about very many other developing countries as well. See, for example, India. That said, I would dispute the claim that Ch…

I encountered code like this in a C99 project recently. I still don't understand it, but I believe it's supposed to be possible.

Usually you can disable this by passing `--disable-silent-rules` to `configure` and/or `V=1` to `make`.

`export MAKEFLAGS="-j$(nproc)"` (or `sysctl -a hw.ncpu` for Mac users). That way you neither need to install Ninja nor remember to pass `-j` to `make`.

`HOMEBREW_NO_INSTALL_CLEANUP` used to be the default. Many users complained about how much space Homebrew used, and were shocked by how much they saved by doing `brew cleanup`, so …
