Today I found myself replacing enums + LUTs with pointers to static structs. The main benefit I found (other than being way more ergonomic to read and write) is that you can construct arbitrary variants at runtime as needed - surprisingly useful! The downside is memory usage and non-serializability.

Since BSS memory is allocated virtually, you can pre-allocate huge amounts of memory for free without dealing with mmap!
char virtual_mem[10ULL << 30];
You need to set `-mcmodel=medium` for BSS larger than 2GB. Interestingly, it starts segfaulting for me at around ~20GB. I wonder why that is?

I might be missing something but I feel like the idea of a texture atlas is kind of silly. You're representing an array of bytes as a rectangle (the atlas) and allocating a rectangle inside to store an array of bytes (the texture). Just put the small array in the big array, no? Keep it all 1D.

I thought the release would have quite a bit less in it, glad to have to show off than I thought!

Cool method of handling GPU allocations - Create a combined CPU/GPU linear allocator struct with both cpu and gpu buffers, then take an allocator pointer to everything! No need for reference counting or tracking. Cleanup is just a buffer destroy and a couple pointer resets.

Anytime anyone in the future mentions git even in passing I am going to evangelize about git reflog. This has saved my ass so many times since I learned about it.

Hated making icons by code in my app, so I wrote a whole ass separate panel for making them lmao.
Only took a few hours to make, surprisingly time efficient!

figured out that literally any api can be immediate mode with good caches behind it

Goddamn it, why is modding tooling always exclusive to windows. We had cross-platform development in the 80s!

IMO it's totally valid (and in some cases better) to use a big flat string as the backing for a text editor. You can easily memmove for inserts in under a millisecond on multi-megabyte text files.
And while people may open and look through larger files (e.g. logs) it's unlikely they will edit them.

Just finished rewriting two ubiquitous ssbm tools in like a week to be faster, simpler, easier to use, more correct, and cross platform. I love my job.

It's so fun learning a field that's adjacent to your main expertise. You constantly think "yep, I'm gonna look back at this and cringe". But this feeling isn't negative for me, it's instead looking forward to the enjoyment of drastic improvement over the next few months.

I really like bsky because there's no one here. I don't want people seeing my lowest behaviour of shouting into the void.

Never thought I'd be saying this but damn, webdev is kinda fun.
At least if you don't do anything crazy. Got a simple server read/writing to a db and from a site working in a few hours. Gonna turn it into a simple forum / chat for fun.
Used sqlite, mongoose, and htmx and it works great.

I really like doing commissions for tournaments. Being self-employed means I don't have any deadlines, which makes my efforts often meandering and unfocused. Having that hard deadline is nice as it forces me to get my shit together. Reminds me of uni, except now people actually care.
