Once upon a time, @Cinememer wrote some alternative lyrics to “Under The Sea”. I couldn’t resist singing them!

I unfortunately lost the audio files for this. Oh well.

The end of Advent of Code 2020 is fast approaching, and we’re nowhere near done. Time to do Day 6!

The problem statement here is a little contrived, as uh, as the days that came before it, but that won’t stop us.

Basically, the input looks like this:

abc a b c ab ac a a a a b

Each line represents one person, and “groups of persons” are separated by blank lines.

This is going to be a short one.

Basically, since February, both shamanas, fredreichbier and I have putting way too much work into the latest iteration of rock, an ooc compiler written in ooc.

I have the pleasure to announce that version 0.9.7, codename pacino is now out, as you can plainly see on the new website: https://ooc-lang.github.io

You can read the release notes to learn what has changed, but basically expect a lot of fixes, some new APIs, and awesome backtraces.

On September 8 2025, around 13:00 UTC, someone compromised Josh Junon’s npm account (qix) and started publishing backdoored versions of his package.

Someone noticed and let Josh know:

Josh confirmed he’d gotten pwned by a fake 2FA (two-factor authentication) reset e-mail:

The phishing e-mail came from npmsj.help (registered 3 days prior) and claimed users had to reset their 2FA:

As I’ve said before, I’m working on a book about lifetimes. Or maybe it’s just a long series - I haven’t decided the specifics yet. Like every one of my series/book things, it’s long, and it starts you off way in the periphery of the subject, and takes a lot of detours to get there.

In other words - it’s great if you want an adventure (which truly understanding Rust definitely is), but it’s not the best if you are currently on the puzzled end of a conversation with your neighborhood lifetime enforcer, the Rust compiler.

I love diagrams. I love them so much!

In fact, I have fairly poor visualization skills, so making a diagram is extremely helpful to me: I’ll have some vague idea of how different things are connected, and then I’ll make a diagram, and suddenly there’s a tangible thing I can look at and talk about.

Of course the diagram only represents a fraction of what I had in mind in the first place, but that’s okay: the point is to be able to talk about some aspect of a concept, and so I have to make choices about what to include in the diagram. And maybe make several diagrams.

So! Rust futures! Easy peasy lemon squeezy. Until it’s not. So let’s do the easy thing, and then instead of waiting for the hard thing to sneak up on us, we’ll go for it intentionally.

Cool Bear's hot tip

That’s all-around solid life advice.

Choo choo here comes the easy part 🚂💨

We make a new project:

$ cargo new waytoodeep Created binary (application) `waytoodeep` package

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.

And we’re back!

In the last article, we thanked our old code and bade it adieu, for it did not spark joy. And then we made a new, solid foundation, on which we planned to actually make an executable packer.

As part of this endeavor, we’ve made a crate called encore, which only depends on libcore, and provides some of the things libstd would give us, but which we cannot have, because we do not want to rely on a libc.
