 Been exploring linear allocators (arenas) and I am converted! Quietly putting together a C base layer library (lovingly named badlib.h) with my most commonly used data structures and simple but powerful logging functions based on this. In ~1.3kloc I already have a lot of powerful options with very pleasant ergonomics. Arenas are great, they can be self freeing without RAII or bundle allocations together and are compatible with fixed memory systems like game consoles. Hope to share more soon! Here is my belated end of the year retrospective. An interesting year no doubt, full of ups and downs. I ended the year very sick but I'm almost fully recovered now. Onwards, to a brighter 2024! And thanks for those who take the time to read this :)  @bd Ups and downs but certainly a lot of ups! You've built yourself a couple of rolling assets that will live on with you as you maintain then, and I hope as you build a catalogue of these things people adore, you'll get financially independant. Looking forward to see what you do in 2024, thanks again SO MUCH for your help with uxn this year :tealheart: Finished mastering all current 28 entries for the Elmet Brae compilation. Can't wait to hear what y'all think of it!

 @bd you're amazing! thanks for handling it, I'm sure it'll sound great :) Need a second opinion? :flonshed: My glasses broke and glue wasn’t cutting it so I reached for my favorite tool: thermo retractile tubing "It's true what they say, now pages quickly become then pages"... Anyway, I finally updated my /now page after 5 months, so if you are curious about what have I been up to you can find it here: Finished optimizing the main drawing functions for uxn-playdate getting speedups ranging from 1.98x to 4.38x. Only screen_fill missing and then it's time to do audio and filesystem stuff. At this point the playdate should be able to handle pretty much any rom you throw at it (within reason). I think there is full speed parity for Oquonie compared with uxnemu. More testing is needed of course, and I could make things faster but not worth it until I can test on hardware. :uxn:  @bd that's sick! I was looking at the uxn core, and I think it could be to run faster. Many times you increment the stack pointer each push and pop, I was wondering if it'd be faster to move it once, and write the values with an offset, so something like PUSH(a) PUSH(b) wouldn't load the ptr twice, just once and write a at -1 and b at -2. Hey fedi, is there someone out there that would like to part ways with a Playdate console? I would like to do some more development for it but don’t feel like waiting 6 months to get a new unit. I could borrow or buy it. Boosts appreciated! Finally was able to test my theory and to my surprise it works! I can control 4 data pins from a link cable to output a 3.3V signal with the press of a button. The trick is that link cable connectors can be quite different. The GBA one has 4 pins/cables, but there is a difference between the big/small connector. A GBC link cable has 6 pin outputs and in my case an extra ground connector corresponding to the outer plate. Either way this is very promising!  @bd I must’ve missed earlier posts about this, what exactly is this project? Wow my partner made such an amazing sweet potato, chickpeas and spinach meal, topped with a drizzle of home made tahini sauce. Beautiful and delicious! #theGalley   12

@bd yes! for #uxn i find arenas to be a really nice compromise between heavyweight memory management and totally naive buffers.
