The GMP model of the Go scheduler: the roles of G, M, and P, and the G state transitions and scheduling flow.

A self-hosted Gitea was flooded by scrapers, draining the monthly traffic allowance quickly. A Caddy UA blacklist, rate limiting on heavy pages, and Gitea origin gzip brought the traffic down noticeably.

Gitea 1.27 requires a nonce for inline scripts; add nonce="{{ctx.CspScriptNonce}}" to script tags in custom templates.

A step-by-step guide on applying the Goldberg/GSE patch to Steam games manually — DLL replacement, interface generation, exe DRM removal, and common pitfalls.

vnStat continuously records traffic per network interface, while picosnitch attributes it to processes; together they narrow an anomaly to its time window and the service responsible.

A note on fixing newuidmap: Could not set caps when building images with rootless Podman on WSL2 Arch Linux.

Windows executables like powershell.exe fail to run inside Arch Linux WSL2 — fix it with a single config file.

Configure Fail2Ban on an Arch Linux host with a rootless Podman mail server, then use UFW to manage bans for SSH, Postfix, and SASL brute-force sources.

Use a VBS script to launch WSL2 with a hidden window, so auto-start at login doesn’t pop up a console window.

Enabling mihomo TUN mode causes a total network outage because system ip_forward is disabled, UFW’s forward policy is DROP, and kernel rp_filter drops TCP handshake packets returning from the TUN interface. Three steps to fix.
