The case for sans-io

Feb 07, 2025

26 min #zip · #rust · #async

The most popular option to decompress ZIP files from the Rust programming language is a crate simply named zip — At the time of this writing, it has 48 million downloads. It’s fully-featured, supporting various compression methods, encryption, and even supports writing zip files.

However, that’s not the crate everyone uses to read ZIP files. Some applications benefit from using asynchronous I/O, especially if they decompress archives that they download from the network.

rock 0.9.8 is out

Nov 18, 2013

A little less than two months after the previous release, I’m happy to announce that the ooc compiler rock 0.9.8, codename columbia is now out.

The impatients can readily skip to the release notes, but for those who prefer a narrative, let me tell you why I’m excited about this release.

We’ve thrown around this idea a lot since the early versions of rock since we have a few rubyists in our ranks, but only recently Alexandros Naskos took matters into his own hands and just implemented the fuck out of it.

Day 5 (Advent of Code 2022)

Part 1

The day 5 challenge actually looks fun!

Our input looks like this:

    [D]
[N] [C]
[Z] [M] [P]
 1   2   3

move 1 from 2 to 1
move 3 from 1 to 3
move 2 from 2 to 1
move 1 from 1 to 2

Which is a visual representation of stacks, and so, for once, we have some serious parsing to do, and that means I finally have a good reason to bust out the nom crate.

Updating fasterthanli.me for 2022

In 2020, I switched from a static site generator to something homemade.

And, as tradition commands, I did a whole write-up about it.

Since writing articles and making videos is now my full-time occupation, I took some time to upgrade futile, my server software, to the latest and greatest the Rust ecosystem has to offer.

Experiments in happiness

May 19, 2013

3 min #life

If you’re a regular, you might’ve noticed the place has changed around a little. Thing is, I’ve been spending time playing around with a radical new concept: happiness.

The year and a few months that I’ve spent working for a start-up were actually a pretty gloomy time for me, both for professional and personal reasons. It took me a while to get out of this hole and start thinking positive again.

Setting up a local Ubuntu Server VM

Mar 05, 2023

10 min #ubuntu · #virtualbox

The first step to using Nix to build Rust is to do so without Nix, so that when we finally do, we can feel the difference.

There’s many ways to go about this: everyone has their favorite code editor, base Linux distribution (there’s even a NixOS distribution, which I won’t cover). Some folks like to develop on macOS first, and then build for Linux.

Day 3 (Advent of Code 2020)

Hello all, and welcome back to Advent of Code 2020, featuring Cool Bear.

Hey y’all!

Let’s get right to it.

The problem statement for Day 3 is as follows: we’re given a map, that looks like this:

..##.......
#...#...#..
.#....#..#.
..#.#...#.#
.#...##..#.
..#.##.....
.#.#.#....#
.#........#
#.##...#...
#...##....#
.#..#...#.#

And we imagine that it repeats infinitely to the right, like so:

An ooc quine

While preparing my next post about ooc documentation yet again, I stumbled upon an old ooc quine of mine. Here it is in integrality for your pleasure:

q := 34 as Char
l := [
"q := 34 as Char"
"l := ["
"]"
"for (i in 0..2) {"
"    l[i] println()"
"}"
"for (i in 0..12) {"
"    q print(); l[i] print(); q println()"
"}"
"for (i in 2..12) {"
"    l[i] println()"
"}"
]
for (i in 0..2) {
    l[i] println()
}
for (i in 0..12) {
    q print(); l[i] print(); q println()
}
for (i in 2..12) {
    l[i] println()
}
