Dyalog APL is fast : ¯1↑5e6↑{(⊂⍋⍵)⌷⍵}10e6?⍤⍴100 This finds the median of 10 million "ages" in just under 50 milliseconds. Granted, with this randomly generated data it's probably doing something smart to avoid a ful

My company basically affords us the freedom to choose how much or how little we work. The ideal target we discuss is 3-day work weeks. Surprisingly, this still affords each of us around 70th percentile salary. Grated, we're not a &quot

Looks like this is the page of designs: https://freesewing.org/designs/ I see three different hoodies on there, with the Hugo looking most conventional.

Somewhat tangential, but I'm curious how big the bootstrap seed for Nix is. That is, if you wanted to build the entire world, what's a minimum set of binaries you'd need? Guix has put quite a bit of work into this, AFAIU, and

Sometimes it's fun to bask in the unimaginable largeness of really big numbers: a googolplex, power towers, Knuth's up-arrow notation. How big can we go? There's something called the Fast-growing hierarchy[0] that quickly mak

This kind of discussion is when I think the "real person inside" intuitive model of human psychology really breaks down. Philosophers have been arguing (circularly?) for thousands of years over the "true nature" of human

As a Guix user who also dabbles in Nix, I am still confused by how to use flakes as a "package consumer". I have a flake (non-declaritively) added to my nix-profile, along with some packages that came from my nixpkgs/config.n

Individualistically, you're completely on point. However, what does your intuition say when you try to think systemically? There is some percentage of people who get screwed by loans due to unforseen circumstances and no fault of their

This reminds me of what a BASIC programmer friend of mine said about C when he first tried it. After many (mostly senseless) debates, I eventually convinced him to try C after showing some bodged-together flashy graphics demo. He got me to

This is a natural response, but I think it also misses a good opportunity. Philosophy setups like this are always massively unrealistic, but the same is true for almost all physics problems, especially so for first year undergrads. We usual

From my reading, the point is that the glass of water doesn't really "have a temperature" any more, since the cooling transition means it's no longer in thermal equilibrium. That is, you could perhaps model the bulk of w

While we're on a tangent. Here's a quick way to list all man pages available on your system: $ man -k '' And if you just want to see the ones for high-level documentation (i.e. section 7), then $ man -s 7

@davidbauer Ugh. These commenters stress me out. In fact, there's potentially an argument that filtering out such personalities actually helps cultivate a good/healthy environment for you personally. To my eyes the comments read l

Interesting bug you found! It sounds our sensibilities are similar regarding cli and tool usage. This is a side note, but as someone who used to use "Bash strict mode" in all my scripts, I'm now a bit bearish on `set -e`, mai
