  • How do you add webassembly support?
    Are you affiliated with https://flatassembler.net/? Source: about 1 year ago
  • Ask HN: What are some excellent pieces of software written by a single person?
    Https://flatassembler.net Unfortunately it won't run on recent Macs since it's written in 32-bit assembly, so some modifications are needed. - Source: Hacker News / over 1 year ago
  • macOS Subsystem for Linux
    Running 32-bit apps, for example. I sometimes code in assembly for fun (my professional work is mobile app developer, though). One of my favorite assemblers is FASM: https://flatassembler.net/ It's still written in 32-bit assembly, which means it won't run on any macOS since Catalina. On the other side, Linux still provide 32-bit compatibility mode. - Source: Hacker News / over 1 year ago
  • Announcing: MiniRust
    Since you mentioned Zig, I'd like to ask a tangential question in case someone could chime in. Is there any way to have Zig output a flat binary? I am looking for a higher level FlatAssembler. [0] [0] https://flatassembler.net/. - Source: Hacker News / over 1 year ago

  • How to improve at x86/C?
    Try https://nasm.us/ as a modern way to use assembly. Source: about 1 year ago
  • Help needed for asm related project
    Assembly is machine specific, have a look at NASM for a more generic assembly language. https://nasm.us/. Source: about 1 year ago
  • vcpkg now (finally) has site with search functionality
    I have a weird problem: when I try using vcpkg on my work laptop, it cannot download nasm. Instead of nasm, I get an HTML page that explains that I am kept safe and secure by CSIS who blocked downloads from this dangerous domain. Vcpkg barfs on the HTML file (as it should).
