Please enjoy this inverse kinematics simulation I made with Bevy!
I'm building a robot arm as a toy project and was looking for a way of controlling it via translating x/y/z rather than changing angles directly.
This seems promising. Maybe with some CV I could make it e.g. grab stuff autonomously.

Every time I try a new thing and it works out ok it feels like I cracked another secret of the universe even if it's the silliest thing

I discovered Niri yesterday and I can't understand why this is not the de facto mandatory standard of interacting with computers already. This is SO GOOD

I engineed the enginee that was engineered today
it doesn't work, I haven't written the firmware yet and the front wheels are all wobbly as heck but ehhh it's still a zero-to-irl-thing in a handful of hours

I tried vibe coding for a couple hours today for the first time and boy do I have opinions.
First up, I made *significant* progress on a very uninteresting crud that I nonetheless wanted to do for ages (workout tracking app). How quickly that happened genuinely shocked me.

Logged back in to ~30 new followers all in one go, so now I feel compelled to say hello to yall and share a tip!
If you do data engineering, check out Apache Datafusion, Ballista, Parquet & Arrow.
It's an all-🦀 stack I've worked with for a couple months. A bit rough round the edges but promising!

How's your day today? Mine is like this: I was told "I struggled to find abstractions as elegant and streamlined as your project's implementation" in a GitHub issue. 🤗

Astrophysics? Ludicrous. The actual field is computer science. You see, monads, which are nothing but monoids in the category of endofunctors, are actually like burritos,
saw someone on this site talking about learning to make a burrito like it's getting a degree in astrophysics. what are we even doing here

I released a new version of both my Practice Tools!
Finally managed to carve some time to implement the radial shortcut menu, operated entirely via controller.
This way you can practice from the comfort of your t̶o̶i̶l̶e̶t̶ couch or portable device such as the Steam Deck.

My year is just now taking off after a very fun flu. Time to refresh yearly resolutions!
Nice things I did in 2024:
- Lifted weights
- Meditated
- Learned CAD and 3d printing
- Maintained hudhook & prac tools
- Adopted 2 cats
- Finished AoC
- Grew my twitch a little
Can't complain! 1/
