Windows 11 ARM64 unattended QEMU/HVF qcow2 installer for Apple Silicon

Windows 11 ARM64 on QEMU/HVF, unattended qcow2 install

This gist contains the reproducible scripts used to create and boot a Windows 11 ARM64 VM on Apple Silicon macOS with QEMU, HVF, EDK2, TPM, NVMe storage, and VirtIO networking.

Files

  • reinstall-win11-arm64-qcow2.sh: downloads the Windows 11 ARM64 ISO from Microsoft, verifies SHA256, downloads ARM64 VirtIO drivers, patches the installer with autounattend.xml, creates one 50 GiB qcow2 disk, installs Windows unattended, switches from installer media to disk-only boot when EDK2 stalls after the first Windows setup phase, and tests VirtIO networking by waiting for real RDP authentication on 127.0.0.1:3390.
  • run-win11.sh: boots the installed qcow2 with fresh EDK2 vars, QEMU/HVF, and host 127.0.0.1:3390 forwarded to guest RDP 3389.

MSYS2-on-ReactOS cross-toolchain build log: patches, flags, rationale per stage

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: 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.

Parse GitHub Copilot Agent Actions logs into a complete AST. Indentation-based scoping, nothing discarded — filter at render time, not parse time.

Copilot Agent Log Parser

Parse GitHub Copilot Agent CI log output into a structured AST. Every line in the log becomes a node — nothing is discarded. Filtering happens at render time.

Architecture

  • AST-based parsing — no regex keyword matching on content for block boundaries. Indentation defines scope. Result lines are never misinterpreted as tokens even if they contain copilot: or function: strings.

How to bootstrap pascal?
fpc source has this commit eb6b7943a946247878b908ec8937c66d5a7f83ae which is a freepascal from 28 YEARS ago.. this is a very barebones pascal program, maybe try from here?
in github all toy compilers are self-hostable which is annoying as they are not bootrstrapable
https://github.com/Kreijstal/Pascal-Compiler an attempt of another toy language to bootrstap pascal compilers.. it is extremely barebones. but it does a hello world
https://github.com/samiam95124/Pascal-P5/tree/master might work?
