2020 Retrospective
Against all odds, it looks like the year 2020 will actually come to an end - in less than a day now. I know! Hard to believe for me too.
A lot of things have happened for me personally, and professionally. It’s been a big year in many ways, and I feel like, to get some closure, I need to highlight some of them.
From “looking at graphs” to “driving to the hospital”
From Inkscape to poppler
What’s next? Well… poppler is the library Inkscape uses to import PDFs.
Yes, the name comes from Futurama.
Turns out, poppler comes with a bunch of CLI tools, including pdftocairo!
Halfway through this article, I realized the “regular weight” on my system was in fact Iosevka SS01 (Andale Mono Style) (see Releases), but the “bold weight” was the default Iosevka.
AOT vs JIT: Why don't we do both?
I wanted to take some time to write about a piece of software I’ve been working on lately, just so you know how I’ve been spending the last few weeks.
Rationale
A few years ago, I designed a programming language: ooc. Even though I’ve done my fair share of Java, C, Ruby, JavaScript, and even some Perl, Scala, Python, PHP, etc., I still find myself going back to ooc because it gives me access to C libs, relatively high-level constructs, and it forces me to write code that’s not too smart.
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()
}
Ludum Dare #25 Post-mortem
Last week-end, I participated to Ludum Dare for the fourth time in a row!

Story
So here is our entry: Legithief. The backstory is simple, yet cunning: you are an ordinary thief practicing ordinary acts of thievery in the houses of ordinary people to make a living. But one day.. you are quietly robbing yet another home, when you are suddenly smashed in the head with a bat.
Cleaning up and upgrading third-party crates
The bleeding edge of rustc and clippy
Typically, you’d want a production application to use a stable version of Rust. At the time of this writing, that’s Rust 1.65.0, which stabilizes a bunch of long-awaited features (GATs, let-else, MIR inlining, split debug info, etc.).
For every Rust release, Mara makes a wonderful recap thread on Twitter, on top of the official announcement.
Day 18 (Advent of Code 2022)
This time around, we’re porting a solution from C++ to Rust and seeing how it feels, how it performs, and what we can learn about both languages by doing that.
See Day 17 for the rationale re: porting solutions rather than writing my own from scratch. TL;DR is: it’s better than nothing, and we can still focus about learning Rust rather than spending entire days fighting off-by-one errors.
Windows dynamic libraries, calling conventions, and transmute
So, how does ping.exe actually send a ping? It seems unrealistic that
ping.exe itself implements all the protocols involved in sending a ping.
So it must be calling some sort of library. Also, since it ends up
talking to the outside world via a NIC (network interface controller),
the kernel is probably involved at some point.
In reading files the hard way - part 2, we learned about dynamic libraries (like libc), and the Linux kernel, and how syscalls allowed us to ask the Linux kernel to do our bidding. For this series, we’re going to have to look at the Windows equivalents.
Deploying at the edge
Disclaimer:
Although I no longer work for the company my website is hosted on, and this article is written in way that mentions neither my previous or current hosting provider: at the time of this writing, I don’t pay for hosting.
One thing I didn’t really announce (because I wanted to make sure it worked before I did), is that I’ve migrated my website over completely from a CDN (Content Delivery Network) to an ADN (Application Delivery Network), and that required some architectural changes.
Day 15 (Advent of Code 2022)
The day 15 puzzle falls into the “math puzzle” territory more than “let’s learn something new about Rust”, but since several folks asked if I was going to continue… let’s continue.
The sample input is as follows:
Sensor at x=2, y=18: closest beacon is at x=-2, y=15
Sensor at x=9, y=16: closest beacon is at x=10, y=16
Sensor at x=13, y=2: closest beacon is at x=15, y=3
Sensor at x=12, y=14: closest beacon is at x=10, y=16
Sensor at x=10, y=20: closest beacon is at x=10, y=16
Sensor at x=14, y=17: closest beacon is at x=10, y=16
Sensor at x=8, y=7: closest beacon is at x=2, y=10
Sensor at x=2, y=0: closest beacon is at x=2, y=10
Sensor at x=0, y=11: closest beacon is at x=2, y=10
Sensor at x=20, y=14: closest beacon is at x=25, y=17
Sensor at x=17, y=20: closest beacon is at x=21, y=22
Sensor at x=16, y=7: closest beacon is at x=15, y=3
Sensor at x=14, y=3: closest beacon is at x=15, y=3
Sensor at x=20, y=1: closest beacon is at x=15, y=3
