Juan Vazquez and Cameron Cunning rejoin the show to discuss how we fared with the 2025 Advent of Code competition.

#dlang
So thinking about asyncronous programming again and how I probably need to ditch #dlang's GC if I want performance and then it hit me:
Why tf is std.socket.Socket an heap-allocated, gc'd class to begin with?!?!
It dosn't uses syncronized that would require a classes monitor, nor does it hold any significant amount of data.
- a
socket_t(fancy 32-bit fd) - a
ushort-enum for the address family (16-bit) - and an bool under windows, which in an asyncronous context we could remove since all will always be non-blocking
So in sum it holds 48-bit of data, while an pointer on modern systems will always be 64-bit (classes are always pointers / by ref in dlang).
Sure, it "uses" inheritance for 2 wrapper types TCPSocket and UDPSocket, which dont actually do anything other than pre-filling the type/protocol arguments in the constructor, which dont even survive after the call to socket(2)...
Is the std really that badly engineered at times or am I going crazy???

Currently working (again) on my async framework in #dlang
I need to say coming back to #dlang after a extensive while of #rust coding, I do miss a lot of features of rust already (tho it's nice for once not fighting against the borrow checker or some strange tokio bugs), like choice-types, pattern matching and traits.
Tho it's nice to just have an decent gc and not the need of wrapping everything in `Arc<RefCell<Box<T>>>` /s
Got plenty of ideas for my async framework after working with tokio (and reading parts of it and mio).

I spent a year of my life making an ASN.1 compiler in D

#HackerNews #ASN1Compiler #DLang #Programming #YearOfCode #TechJourney
#introduction Heyo, I'm Luna, the lead developer of the open source Inochi2D character animation format, lead maintainer of DKOS; the DLang SDK for the SEGA Dreamcast, DLang compiler infrastructure contributor, DSP programmer, and hobbyist gamedev.
I also run my own business, Kitsunebi Games (https://foxgirls.gay) to manage all of my work on game dev tooling.
I maintain a lot of #dlang libraries aimed at multimedia development.
About 8 years ago I tried to convert Titanion (a 2.5D shooter game by Kenta Cho) from #dlang to #rust as a means to learn Rust and make the game open to more developers. The porting effort was also done in part as a live coding session at @OpenLabAugsburg. After about three month of intense head scratching I gave up because the Rust borrow checker does not like spaghetti code and I was a beginner. Now I tried again but with C++. I succeeded. So here it is: https://github.com/mwarning/titanion
Spent some time today updating and expanding my #notes on #DLang: https://felix.plesoianu.ro/languages/notes.html#D
It's online! ⚔️
Samerion: The Hunt — out NOW ↙️
huh... tried to compile #dub from source (a build system for #dlang) on #openbsd but the compiler (using #dmd from the package) segfaults while processing "semantic3 json"? the core dump's backtrace is like 30 layers deep and incomprehensible (to me)... 😰
succeeded in building dmd with debug symbols, but when i try to use that to compile dub, it complains i havent installed object.d or something.. guess i need to figure out how to do that to have recognizable symbols in gdb...
It's nice to step back and reflect every now and then.
After spending most of the week buried deep in the game code and getting my game to run on Windows for the first time in 2 years, Linux is my daily driver and my windows PC built circa 2016 has been in storage.
I thought I'd run #MultiMall through gorce.
Enjoy.
Forgot to put up the ./lines.sh result again.
Day 1200 of #MultiMall as been a productive one, lots of systems finally coming together.
I've actually been able to 'play' the game and I've discovered a few more bugs to squash but progress is progress.
Here's to several more weeks of work.
