racket-nonogram can now show you any mistakes you’ve made, in case you can’t figure out what the issue was and don’t want to have to completely start over

racket-nonogram now supports automatically generating “mega nonogram” puzzles from standard puzzles

while working on this I have begun to understand why there are no mega picross implementations on the internet

racket-nonogram now supports networked co-op multiplayer (and has a README) github.com/lexi-lambda/...

it also supports mega picross-style puzzles now (I have not seen any other implementation of this in existence outside of the switch picross games)

mflatt: let’s ditch s-exps to make our language more accessible :) also mflatt: rhombus defines eight different ways an identifier can have a binding in the core language and the standard library adds several more. here is the documentation for how to define a basic datatype. do you like this

really cool that stackoverflow-the-company is making such terrible choices that it’s gotten a wine mom with a radio and film degree to start fedposting in their moderator-only chatroom

who else up experiencing some sort of "new-year" mind vacancy

it turns out to be a pretty big problem for internet “communities” how many people absolutely love feeling righteous anger and like to find as many opportunities as possible to be as mean and uncharitable as they want without feeling guilty

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

DFB7-2278 is a SNES Game Genie code to make it so that enemy HP always shows up in Chrono Trigger regardless of whether you have the Sight Scope equipped. just in case anyone was wondering

just wrote 2,300 words about register allocation langdev.stackexchange.com/a/4326/861

I’ve been thinking about this a lot lately, and I would add something: we must believe in something good. We must allow ourselves to believe that there are things in the world that are good and beautiful and true, and that they are worth defending and fighting for, without compromise.

update: someone has posted a remarkably extensive answer to this english.stackexchange.com/a/628758/17950

@briangoetz.bsky.social would be lovely if you could write an answer to this question on langdev :) langdev.stackexchange.com/q/4265/861

does anyone know the origin of the variant usage of “grovel” to mean “to rummage” or “to exhaustively search” commonly used in computing circles? if so, please answer my question on English Stack Exchange about this! english.stackexchange.com/q/628648/17950

wrote an extremely lengthy answer to an interesting question about typechecking matching on polymorphic variants in a language with a sufficiently global type inference scheme, which I think illustrates just how challenging even “simple” things can easily become langdev.stackexchange.com/a/4250/861

got to write this extremely fun answer on langdev stack exchange this evening and man I love Daan Leijen so much langdev.stackexchange.com/a/4242/861

learning that the iOS app for this website does not allow me to receive push notifications for replies but not follows. cool cool

I guess I will try posting here: I’ve finally given in and published a small mountain of random bits of racket code I’ve had sitting on my hard drive for ages but haven’t had a good place to put it (and this is not even all of it, as I’m documenting it as I go) github.com/lexi-lambda/...

ok can someone explain to me why like 15 people have followed me here in the past 36 hours despite this account never having made a single post. which one of you ratted me out
