My latest hobby: bossing Codex to try and come up with interesting Ruby code golfing solutions and (not so) novel algorithms rubyinside.com/romangolf/
What Happens When You Get Codex to Golf Ruby
How an hour prompting OpenAI Codex to keep making a piece of Ruby code smaller revealed some neat code golfing tricks and reimplemented an obscure trick from 1976. My dad was always bemused by the inv...

@tflangkaas.bsky.social Been reading your post about Roman numeral algorithms! What do you think about this? bsky.app/profile/coop...
Peter Cooper@cooperx86.bsky.social · 2w agoThe funniest Roman numeral generator (in Ruby) I've seen yet: def r(n)=n<1?'':r(n/10).tr('IVXLC','XLCDM')+(n%=10;n<4??I*n:n<5?'IV':n<9??V+?I*(n-5):'IX')

Nice to see Ruby being represented at the World Cup final.
The kids' school spent years rolling out wifi to every classroom, giving out money for every kid a tablet, moving schedules and elements of classwork to the devices, etc. Now the government's new ban on "smart technology" unwinds all of it 😂
TIL up until the mid 1900s, artists could buy a paint made out of ground up flesh from Egyptian mummies and it was used in numerous famous artworks: en.wikipedia.org/wiki/Mummy_b...

Midjourney getting into body scanning is fine and dandy, but will you only be able to view your results on a public Discord channel?
Back in 1987, Apple released an album called "The Apple Boogie" and handed it out at conferences. You can listen to it in all its glory here, including a weird parody of the Ghost Busters theme.. www.youtube.com/watch?v=chJH...

I love finding clearly AI-generated "tech news" sites so I can block them in future. $1m for a company that just received $12.5m in funding.. sure! 😂
Hot take, but while Layla is a good song, the instrumental second movement is 100x better than the rest of it.
I have a pure Ruby implementation of Doom (to be released soon). You *can* play it, but it's really for benching Ruby implementations and JITs (ala Optcarrot). Initial results: Ruby 4.0.2 without YJIT: 73 fps Ruby 4.0.2 with YJIT: 207 fps TruffleRuby 34: 235 fps
Rubyists! I am reviving Ruby Inside after 12 years of hiatus. I have too many Ruby things I want to blog about :-) So far I've got the archive up and running at rubyinside.com/archives/ - it's a bit of a Ruby time capsule..

I was asking Claude about what animal has the worst life, and this sentence out of context feels like peak horror: "he bites into her flank and his body literally dissolves into hers, losing his eyes, fins, and organs until he's just a pair of gonads attached to her bloodstream"
You might be old, but are you "radio stations have a helicopter flying around to look at traffic jams" old?
Got experimenting with Matplotlib and GeoPandas. So here's countries colored by the colors hiding in their names:
Rubyists: want to generate embeddings of text with a 25MB model that punches far above its weight and runs on CPU wherever you want? `gem install informers` and then this is it.
A huge collection of classic text mode fonts in modern formats (TTF, WOFF): int10h.org/oldschool-pc... .. think EGA, VGA, Tandy, Acorn, all the 80s computers, etc.
Looking through an SD card of photos from 2006. The same product now is 5x more expensive than then 😂
I'm looking through a SIMTEL CD from 1992. I see a (rare for then) open source C compiler called Small-C. I Google to see if anyone has ported it to modern systems. A dude made his latest commit to one an HOUR ago. What are the odds.
Discovered the source code for QBasic. First step in the build notes: "1. Make sure you've got a lot of memory (around 570 K)"
Had a funny "Scunthorpe problem" on a social site I run today. A legit looking post kept getting rejected. Turns out the word "specialist" contains "𝒄𝒊𝒂𝒍𝒊𝒔"...
Just had a heck of a 30 year flash back: Borland Resource Workshop! It let you open EXEs/DLLs and edit their resources, text, and sometimes even the form layouts. I used to customize Windows 3.1 apps with it for fun. Any fellow oldies remember it?
I love how Wikipedia covers hiphop beefs the same way they cover armed conflicts
Rare moment: I have three full days to myself. Let's see what carnage I can produce 😂
Went from MacBook Pro M1 Max to MacBook Air M5 two weeks ago. Faster, form factor better, 15" way better than 14". Love it. Only complaint: it needs a USB-C on the right side!
I've only just learnt macOS has /usr/bin/time (NOT the shell one!) which has a -l option for showing memory/resource usage of whatever you ran!
