Build Python on musl

Docker error

Context: Working with python-build-standalone project on Manjaro Linux, attempting to build Python for x86_64-unknown-linux-musl target. The Docker build process was failing during package installation phase in Debian-based containers.

Problem/Need:

• Docker build failing with "Unable to locate package" errors for essential build tools
• Outdated Debian Jessie snapshot repositories from March 2023 were no longer accessible
• Multiple packages (bzip2, ca-certificates, curl, gcc, make, etc.) could not be installed in Docker containers

OpenTabletDriver Autostart

Context: Setting up OpenTabletDriver daemon auto-launch on a systemd-based Linux system where the service failed to start automatically due to unmet display server conditions.

Problem/Need: The opentabletdriver.service failed to start because it required DISPLAY or WAYLAND_DISPLAY environment variables that weren't available when the systemd user service initialized.

Solution/Approach: Created a systemd service override to explicitly set environment variables and remove restrictive conditions:

# Create override directory and config
mkdir -p ~/.config/systemd/user/opentabletdriver.service.d/
cat <<EOF > ~/.config/systemd/user/opentabletdriver.service.d/override.conf

Certbot: SSL Auto-renewal

Context: Managing HTTPS certificates for multiple domains via Certbot, previously done manually. The system lacked default renewal tasks.

Problem/Need: Automate certificate renewal monthly via cron while preserving custom Nginx paths (/usr/local/nginx/conf), ensuring zero downtime.

Solution/Approach:

1. Create cron job (run as root):

   sudo crontab -e

Cursor: Bypass model region-blocking

Context: Cursor’s AI models are region-locked, requiring a proxy for access in unsupported regions.

Problem/Need:

• While a system-wide TUN proxy works, it’s not an elegant solution.
• Attempting to use proxychains caused crashes (zygote_host_impl_linux.cc errors) and network timeouts.
• Needed a native proxy solution to avoid Electron compatibility issues.

Git: Modify author information

Context: In a Git - based project, there were multiple commits made with an incorrect author. To ensure proper attribution, it was necessary to change the author of these commits to Chen Yichi <trswnca@yeah.net>.

Problem/Need: Change the author information of six specific commits in the Git repository to Chen Yichi <trswnca@yeah.net>.

Solution/Approach:

1. Start an interactive rebase:

git rebase -i 2028312c0e4325e5eccbc72f12fe47adbce2df98^
