The front end of the pool

I’ve been interested in reactive JavaScript for a while. At memoways, we strive to build snappy user interfaces for clients who like to interact with their data with as little latency as possible.

In the past two years, I learned front-end development on-the-fly, as the needs of the clients required it. Two years ago, I was still using jQuery. Then, I discovered space-pen thanks to my colleague Nicolas. It was nice to have proper ‘view’ objects, and use jQuery’s event system to have messages propagate throughout a hierarchy.

The day 7 challenge talks about trees! File trees that is.

The temptation to solve it before starting to write this article so I don’t look silly is high, but I’m explicitly not doing so, so that we can bang our collective heads against any walls at the same time, and see how we can get out of it! Trees are serious business!

Part 1

The sample input looks like this:

Falling out of love with warp

Back when I wrote this codebase, warp was the best / only alternative for something relatively high-level on top of hyper.

I was never super fond of warp’s model — it’s a fine crate, just not for me.

The way routing works is essentially building a type that gets larger and larger. One route might look like:

 bye = warp warppath | | name

In hours, I have played more of The Binding of Isaac than any other game in my Steam library. Edmund McMillen said he wasn’t expecting it to be a hit, and has since proceeded to be proven thoroughly wrong.

It is kind of a big deal among a certain crowd: as I’m writing this, the second season of the Binding of Isaac Racing League, hosted and commented by Crumps, is in full swing - even though the game was certainly not designed for that!

In our last article, we managed to load and execute a PIE (position-independent executable) compiled from the following code:

; in `samples/hello-pie.asm` global _start section .text _start: mov rdi, 1 ; stdout fd lea rsi, [rel msg] mov rdx, 9 ; 8 chars + newline mov rax, 1 ; write syscall , , "hi there", 10

I know what you’re thinking: haven’t we strayed from the whole “content pipeline” theme in this series?

Well… fair. But compiling and distributing software is part of software engineering, and unless you’re in specific circles, I see that taught a lot less than the “just write code and stuff happens” part.

It’s time for some personal and professional news!

TL;DR: I started a podcast with James, I’m stable on antidepressants, I’m giving a P99 CONF about my Rust/io_uring/HTTP work, I’m trying on “they/them” as pronouns, I’m open-sourcing merde_json, rubicon and others, I got a divorce in 2023, I found a new business model.

Now that we’re on the same page: let’s unpack this a bit!

Long story short: a couple of my articles got really popular on a bunch of sites, and someone, somewhere, went “well, let’s see how much traffic that smart-ass can handle”, and suddenly I was on the receiving end of a couple DDoS attacks.

It really doesn’t matter what the articles were about — the attack is certainly not representative of how folks on either side of any number of debates generally behave.

I’d like to think that my understanding of “async Rust” has increased over the past year or so. I’m 100% onboard with the basic principle: I would like to handle thousands of concurrent tasks using a handful of threads. That sounds great!
