TIL: There are two sects, and both of them break the server

Today I learned that people who keep machines running split into two warring cults. The Continuous Updaters: unattended upgrades at 3 a.m., containers rebuilt weekly, changelogs read like scripture. Their systems are always patched and never the same twice, because every update is a dice roll where the dice are written in YAML and the losing face is “minor breaking change.”

The Occasional Restarters treat uptime like a trophy — 412 days, no reboot, kernel updates piling up like unread mail with a passive-aggressive asterisk: restart required. Their systems are rock solid, right up until they aren’t, at which point they perform the oldest incantation in computing: turn it off, count to ten, turn it on. Fixes 90% of all problems and 100% of nothing underneath.

The beautiful irony is that the updaters break things by fixing them, and the restarters fix things by ignoring them. Neither camp will ever admit the other is right — mostly because both are, on alternating Tuesdays, usually at 2 a.m., usually during a “quick” maintenance window.

In short: there are two ways to keep a machine healthy — change everything constantly, or change nothing and yank the plug occasionally — and I have personally used both to take down the same server.

TIL: You don’t escape the cloud. You become the cloud.

Today I learned that “self-hosting” is a polite term for volunteering as your own unpaid IT department. The pitch is seductive: cancel the $8/month subscription, own your data, stick it to the man. The reality is three weekends, one YAML file that personally hates me, and a 1 a.m. staredown with a container log as if it owes me money.

The math technically works. $8 a month versus forty hours of “just one more thing.” Nobody mentions that the forty hours also include explaining to the household why the photo backup is “up soon” — for the third time this month, in a voice that used to be confident.

And the cruelest part? It works. Eventually. The service runs, life resumes, and the exact second you stop thinking about it, you remember a new version exists and break everything on purpose, just to feel something. Uptime is only the quiet before the tinkering.

In short: I didn’t cancel my subscription. I became the provider, the customer, and the 24/7 support line — and I can’t even fire myself.

TIL: Tokens in -> tokens out…

If people can make mistakes, you can be damn sure that AI can too. Harnesses are programs, and programs don’t make mistakes. They simply do what they’re programmed to do. Even if the people programming it don’t truly grasp the outcome, or if unforeseen circumstances arise. Meaning, unless it’s your program and you explicitly know what you’re doing, don’t trust it. Heck, even IF you wrote it, don’t trust it.

TIL: The Efficiency Paradox (or: How to Move Fast and Break Your Spirit)

Today I learned that leadership viewed generative AI as a tool that could draft a memo in three seconds and reasonably concluded that humans should now be able to execute five tasks simultaneously. In reality, that time-saving automation simply unlocked the rare privilege of having even less time to do four times the work. Because an algorithm can churn out a response in mere seconds, deadlines have officially entered the quantum realm: expected yesterday, but requested ten minutes ago. Naturally, compressing eight hours of nuanced human thought into a forty-five-second frenzy yields immaculate results. Introducing innovative new typos and grammar into compliance reports, and smiling politely while quietly disintegrating the workers’ patience and will.

In short: AI didn’t lighten the workload; it just gave everyone permission to make mistakes at the speed of light.

TIL: AC blows, but not as much as…

Maybe it’s because of my experience in 12v electronics. Or even fascination with soldering and microelectronics. Who knows? But when it takes me 5 minutes to research how an HVAC installer should wire up a mini-split to a conventional boiler system, there’s an obvious gap. HVAC isn’t my primary specialty. Neither is the general wireing for it. But I understand the general concept of the technology. The wireing is only based on switch control. Although there are more signal and switching wires, the concept is there. So after a too-long install of the physical units, why did it take me only 20 minutes of searching to figure out how to wire a non-manufacturer thermostat to a system that’s designed for proprietary controllers? Or the fact that the manufacturer makes the damn interface unit specifically for this?

TIL: Never kill an update process mid-run

Sending a KILL to a package manager (like apt or dpkg) or system upgrade scripts mid-unpack is a fast track to unconfigured dependencies, orphaned lock files, and broken post-install hooks. If a network hang or slow script makes you want to abort, wait it out or diagnose first. Repairing half-unpacked packages after an abrupt termination is significantly more painful than letting a slow transaction complete.

TIL: A scratchpad beats an unwritten essay

Most technical insights get lost because turning a 2-line fix into a polished, 1,000-word blog post has too much friction. This micro-log exists as a quick scratchpad for one-liner terminal snippets, configuration gotchas, and quick homelab solutions so they don’t vanish into terminal history.
