Using Typst as a general-purpose evaluator (no PDF involved)

Typst has no typst eval subcommand, but typst query is one in practice. It runs the full compiler and emits JSON instead of a document, which is enough to use the language as a scripting runtime — map/filter, regex, dictionaries, recursion, date formatting.

Everything below is verified against Typst 0.14.0 on Linux.

Salvaged Wine macOS display-mode experiment

This gist preserves the only unpublished source change left by the inactive Codex task "Investigate QEMU slowdown". The original worktree no longer exists.

The patch is based on Wine fork commit ba1088155ce8cb332d2f04a703cc8df36d060423 (macos: enable ARM64 GDI text build) from Kreijstal/wine-kreijstal, branch kreijstal-fixes.

It experiments with:

Subject: [PATCH 1/7] build: recognize the AArch64 MSYS target

Teach the top-level, newlib, and winsup build logic to configure aarch64-pc-msys. Select the ARM64 runtime sources and direct linker path while retaining the existing x86_64 link rule.

MSYS2-on-ReactOS cross-toolchain build log

Linux-hosted cross toolchain targeting x86_64-pc-cygwin (validation phase) before morphing to x86_64-pc-msys. Goal is bringing the full MSYS2 environment up on ReactOS; ReactOS will gain whatever Win32/NT API surface MSYS2 needs (we do not fork the runtime to paper over ReactOS gaps).

Recipe transcribed from NixOS/nixpkgs PR #444470 (pkgsCross.x86_64-cygwin, head e098bea39d) into plain shell scripts (no nix on host).

Workspace: ~/git/msys-cross/{src,build,prefix,patches,scripts,logs}.

Reentrant radare2: auto-resume your project per binary (no -p, no wrapper)

Reentrant radare2: never lose your renames again

By default, radare2 forgets everything the moment you q. Every rename, comment, and flag evaporates. This is the 5-minute setup that makes r2 remember per-binary: you just run r2 /path/to/binary and your previous session comes back automatically — no -p projectname to remember, no wrapper function to type.

• Open r2 ./foo.exe → previous analysis, renames, comments, flags all restored.
• Quit with q → prompt "save project?" so you can't lose work by accident.
