Metadata schema choices for content libraries

Structured metadata only works when it matches how people actually retrieve content. I have seen neat schemas fail as soon as the library meets real records, and tarot makes the problem obvious. If the fields do not support search, filters, and odd edge cases, the catalogue stops being useful.

Federation trade-offs in self-hosted social feeds

Federation looks tidy until you let it touch the edges, and then the odd cases arrive fast. I prefer self-hosted social feeds that stay explicit about...

FireAvert Z-Wave stove shutoffs for offline safety

FireAvert’s setup does the part that matters without asking Home Assistant to babysit it, which is exactly how I want stove protection to behave. The...

Tool boundaries in incident response for AI agents

When an autonomous AI intrusion lands, I care less about the model’s output and more about whether my tools still work. If a hosted service refuses the forensic workload, your response path is already...

Flatpak pipewire escape through module loading

Founder-led startups and the cost of replacing generalists

AI can make founder-led startups look busier than they are, which is exactly why I distrust it when the team is already thin. The easy wins are real, but once you remove the generalist, you often...

RCU and refcount faults in Linux kernel net/sched

RCU and refcount faults in the Linux kernel net/sched path are the sort of bug I like least, because the refcount check arrives after the damage is already done. On a busy CentOS 9 box, the race is...

Simple Caddy access rules for cgit

I keep cgit behind Caddy access rules because the decision belongs at the front door, not buried in the app. It is a blunt setup, but it keeps browser noise out, leaves Git clients alone, and avoids...

Skipping fenced code blocks in Neovim Markdown outline

Neovim Markdown outline navigation gets ugly fast if you let fenced examples count as headings. I fixed that with a small state flag, a blunt scan, and no ceremony; the sort of change that quietly...

LLM-assisted pull requests and CLA friction

LLM-assisted pull requests tend to look harmless until the CLA, provenance, or disclosure rules kick in. I have seen good fixes stall there, not because the code was bad, but because the project had...

CVE-2020-8561 and DNS proxy TOCTOU risk

CVE-2020-8561 is the sort of Kubernetes CVE records problem I trust least, because the bug is in the behaviour, not a neat patched release. If your tooling only reads version fields, it can miss the...
