  • I’m not sure I would call the humidification passive given the action of the fan, but yes, in the limit it will push to 100% humidity. One thing to note with that kind of setup is that mildew/mold can quickly build up in the unit and, if it keeps the ambient humidity high enough, in the dwelling. So, it can just trade one air quality issue for another. Buildup in the unit can be prevented by adding a small amount of biocide to the water (formulations for humidifiers are usually alkonium salts). However, it well eventually encrust the wick and force replacement or washing (wear gloves).

    Warum würden die Softwareunternehmen ihre Software optimieren? Sie alle verwenden heuzutage KI-Modelle um sie zu “verfassen”, und weder die Modelle noch die Software und Tests selbst werden üblicherweise auf den eigenen Computers ausgeführt. Jeder wird gezwungen, die Hardware immer noch zu mieten und nichts reichendes besitzen zu dürfen.

    Ah, voluntoldment. We just had a big round at my workplace, but at least no one only a couple people up the chain are engaging with the autofellatory fiction that AI will pick up the slack. Even still, they canned the hypercompetent plant engineer that everyone liked, so half his team left and a couple of our projects are dead in the water because of it. /vent

  • Huh, didn’t know that gardeners were essentially doing silica sol-gel syntheses. A note of caution: contact with TEOS and other organosilicates can and will cause permanent eye and lung damage (converts to silica, and, broadly, rocks in lungs bad). Make sure your work area is well ventilated and ideally use some kind of eye protection against splashing, don’t touch your face, and wash up when done. TEOS is less reactive once in contact with water (it hydrolyzes to silicic acids and eventually silica, with rates depending strongly on pH).

    Also note that adding TEOS to water does slightly lower pH due to this hydrolysis reaction, but it is much less severe of an adjustment than potassium silicate.







  • I was on arch as a vestige from my school days, having never quite found the time to switch to something more stable. When I saw the news over the weekend, I checked and found 1 would-be-infected package on my machine that was thankfully months out of date. I’m well past the point of wanting to examine PKGBUILDs every time (hence the out of date package). But, instead of just removing AUR packages and sticking to arch repos, I decided to sweep up the technical debt by wiping and installing Fedora. I’m liking it so far, minus the absolute pain in the ass that is Nvidia on Linux. Fuck academics and their insistence on writing everything targeting CUDA; otherwise, I’d have saved a good bit of money a few years ago with a much more compatible AMD card.






  • Alkylation is any reaction that attaches a saturated hydrocarbon group through one of its carbons to something else (more loosely, the hydrocarbon group may contain atoms besides H and C and only be saturated at the point of attachment). It’s pretty common in organic chemistry. The meme is portraying a humorous obsession with alkylation by listing alkylation agents and things the author wants to alkylate, including some unconventional or inadvisable targets.

    Incidentally, a lot of alkylation agents are carcinogenic because they alkylate DNA.
