inspired by CLAUDE.md, I’ve started putting markdown files named after coworkers into work code repos so I can remind them to stop doing shit to the codebase that annoys me

for some reason they’re all mad at me now, which means ill be adding commands to JEREMY.md for an attitude adjustment

I kinda like the `.or_panic()` name. In an ideal world where Rust has optional parameters and anonymous unions (still tagged), I'd even see a single `.or_panic(msg: &str | None = None)` method to reduce verbosity (but this is obviously fictional and subjective).

oh i just realized i was only thinking about the variance of type parameters, if we are talking about the variance of function parameters then i agree it is very much unsound and evil

by "by default", do you mean whenever a type parameter is unused? if so, does this often happen? i fail to see the problem tbh

Yay!

I have published my first new blog post in four years lexi-lambda.github.io/blog/2025/05...

I am disappointed in the AI discourse steveklabnik.com/writing/i-am...

Yah I used to check that sub somewhat regularly and I agree, I hope some non-Discord alternative will emerge in the future

All of that to say: do not abbreviate your "term" variable to "trm", it is not worth it.

Still, I am convinced there is objective truth in what is or is not good code. I swear one day I will make blog posts on how I personally write "good code".

While programming language theory is a formal science, I feel like "good code" is more like a social science. It is really hard to prove that a programming style or practice is better than another because the results are largely dependent on what the subjects are used to.

Broke: frontend vs backend
Woke: revenue generator vs cost center

I kinda believe using => as a shorthand for greater-or-equal ≥ was a mistake, now I can't use it as a shorthand for the double arrow ⇒ ! We should have used >= instead, which also looks more like the actual operator.

"to democratize art is not every person having a cute drawing made in seconds, to democratize art is every person having time and health to learn and make art if they chose to, and mainly to have the means to think and relate introspectively with art."

Also use PascalCase even for primitives types, use `Never` for the never type (why use a symbol for something so rare !), and a pronounceable keyword for functions (`fun`, `func`, `def`...).

On more controversial topics, I would use kebab-case for identifiers (IMO the most readable naming convention, although quite rare unfortunately), use `.` everywhere instead of `::` (so ugly !), and use indentation-sensitive grammar instead of braces.

Hhhhm, on the hot topic of language syntax, I would have a single expression for pattern matching (`is` or `let` expression, like the contentious RFC of last year) and use `[]` instead of `<>` for generics (byebye turbofish).

OMG my dumbass just realized that the pun is that "le chat" means "the cat" in French. That logo 🥹

Damn I thought the logo was pretty uninspired but now I really like it, nice.
