A tool that builds golden images and clones them into working VMs was written against vCenter, then forked for bare ESXi. Moving it to Proxmox looked like the expensive one — new vendor, new API, new vocabulary — and turned out to be two files, because Proxmox has a real cloud-init datasource and that deleted the most intricate code in the project. What actually cost time was underneath the API: a default CPU model that panics glibc on Enterprise Linux — at one baseline for EL9 and a different one for EL10, so the fix I set once was wrong within the afternoon — offline image edits that land with no SELinux label, and a clone that is instant until one innocuous dropdown makes it expensive.
macOS is a Unix, but it stopped being close enough the moment your production target became a Linux container. AppBox turns Apple's container tool into named, persistent Linux machines that boot systemd, share your home directory at the same path, and arrive with the thirty-odd command-line tools a base image forgot — all from an icon by the clock. If lxc launch is muscle memory, this is that reflex, on the laptop.
Every network answers three questions constantly: what is this machine called, what address does it get, and who is supposed to be using it. The enterprise world sells appliances for that; everyone else has a hosts file, a router tab, and a spreadsheet that was accurate in March. This is how two small self-hosted tools — Nexus IPAM and DNSMAQ-MGR — grow into most of what an Infoblox-class DDI suite does, and how a VM deployer on top turns the address plan into one-click provisioning.
A 25-gigabit QNAP switch with an excellent chassis and a miserable management story: a sluggish web GUI, no SSH, no Telnet, and not a page of documentation. But a web UI is just a program talking to the switch over the network — so I read its minified JavaScript, and one regex mapped the whole hidden REST API: 126 endpoints, before making a single call. This is how that turned into qsw.py, a tool that manages the switch from a text file instead of a spinner.
The ASUS ProArt PX13 (HN7306, "Strix Halo") plays audio over HDMI out of the box, but its internal speakers are dead silent — PipeWire shows only a "Dummy Output". Real, persistent sound turned out to require peeling back three independent bugs stacked on top of each other: a calibration firmware blob that ships only in ASUS's Windows driver, a missing (and separately broken) ALSA UCM profile, and an AMD ACP/SoundWire controller that doesn't survive boot or suspend/resume. A root-cause tour of each layer, and the fix for it.
