Oscar Toledo G. just released a boot sector real-time animated ray tracer, based on the BBC BASIC one, which can be run from a floppy disc boot sector with no OS #small-is-beautiful #3D #graphics #raytracer #asm
Explanation and movie of the #3D #graphics #raytracer in 10 lines of #BASIC (in the family of the BBC BASIC one, but for an Atari). #small-is-beautiful
Johan de Jong’s #Stacks-Project is a single-maintainer Wiki (?) of 7300 pages about #algebraic-geometry (including #3D), of proofs, theorems, lemmas, etc., looking like “a traditional textbook”, winning de Jong the AMS’s Steele Prize #math
Jacob Lurie’s "Kerodon" is “an online textbook on categorical homotopy theory and related mathematics” modeled on the #Stacks-Project
Gerby, used by #Kerodon and originally intended for the #Stacks-project, lets you write a large hypertext in #aTeX and navigate it in the browser
the "Stacks Project" is “an open source textbook and reference work on #algebraic-geometry” including #3D and accepts third-party contributions

"Reko Decompiler" is written in C# and supports #disassembling 68k, ARM, MIPS, PowerPC, Risc-V, Sparc, x86, Z80, etc., code (and even decompiling to C), with a GUI and command-line interface, mostly targeted at #retrocomputing I think

#Agner Fog has written a GPL utility called objconv useful for, among other things, #disassembling an ELF or COFF/PE file into assemblable assembly (in NASM, FASM, gas, or MASM syntax) with useful labels, but it only supports Intel/AMD architectures. Faced with a RISC-V ELF executable it disassembles it as amd64!
