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 you’re 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’m at a loss to explain the stability of those cumulenes… hehehe

In the simplest case, absolutely. I ran into black screens and wayland issues due to a combination of needing to enable simpledrm in the command line and working with secure boot. Not too much extra once you figure it out, though.

Regarding the wait time, maybe I just got lucky, but just waited for my CPU usage to come back down and spammed modinfo -F version nvidia or some such until it stopped erroring. My actual hang-up was getting simpledrm working and then secure boot.

Yep, checklist of basically everything I went through over the weekend. Sorted now, thankfully

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saw the news over the weekend, I checked and found 1 would-be-infected package on my machine that was thankfully months out of date. I’m well past the point of wanting to examine PKGBUILDs every time (hence the out of date package).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.

False it’s a torus. I think. Resolution is a bit low to say for sure.

I was told there would be dopamine, but all I got was apparently ethylbenzene with some unspecified functional groups. Where’s the dopamine, Lois?

Edit: ironically, the last example (“alkylating agent itself”), despite sounding the most absurd, is actually probably the most feasible example to alkylate

The position of the drawn alkyl group seems to imply a bromonium, though, which is decidedly less easy to make.

Living things, on the other hand, conveniently have a bunch of cytosine and N-terminal proteins…

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.

Looks suburban; I don’t suppose the local law enforcement is supported by traffic and parking tickets? Just sayin, your incentives may align…

Obsidian is pretty good. I currently use Logseq, which has a slightly different model that clicked a bit better for me. As a bonus, it’s open-source.

Wasn’t also /r/ich_iel a big part of the reddit exodus at one point?

This one got me giggling. And now I’m trying to explain to my MBA colleague what’s so funny about a pun from an (admittedly less and less) obscure niche of the programming community.

Yep, sorry for going between terms. Also, if the confusion stems from just calling it “alcohol” at one point, I was using the word in the more general chemical sense (molecules containing a C-OH group), a class to which isopropanol and ethanol belong.

No dunking, and make sure what you’re buying is mostly alcohol (> 95%) and not water/alcohol mixtures often used for disinfection. Using in combination with e.g., a toothbrush is probably your best bet. IPA (and acetone) can strip some adhesives and cause certain kinds of electrical insulation to swell or dissolve, so a targeted approach is better. IPA is flammable (though less so than acetone), so be careful/well ventilated when allowing parts to dry, and ensure parts are fully dried before reconnecting to power.

IPA itself is only about twice as toxic as ethanol and certainly less problematic by inhalation than tar in the long run. I wouldn’t bother with a mask mostly because it won’t do shit unless it’s a cartridge respirator. However, IPA can sometimes facilitate skin absorption. IDK specifically about tar buildup but recommend wearing gloves (disposable nitrile is fine).

don’t forget to make the space non-breaking :D

I think the framing as “myths” also helped the show. The experimental result was generally either wonder (“oh wow, it’s really true!”) or self-satisfaction (“we proved wrong something that Other People actually think!”); good outcomes either way. It helped keep the audience happy regardless and made them feel like something was actually accomplished that they could relate to. Sure, you can get some of that with other popsci shows, but the demos/experiments are often presented as a known answer with low stakes, leaving it harder to connect to a “so, what?”
