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).

… this sounds absurd to me, at least as stated wrt the enzymes “dissolving” the floaters. Your body does not like foreign proteases floating around. I am also skeptical that the enzymes would survive denaturing and pepsin et al. in the stomach and duodenum (empty stomach or not), get absorbed intact, and somehow not get inactivated by the immune system (again, rogue protease = bad). Not to say that your floaters weren’t reduced (though the brain sometimes will just learn to ignore them) or even that the supplement wasn’t responsible via metabolites. Just, action of an intact enzyme itself seems unlikely. Corrections welcome; I’m going off my gut here and am not a biologist.

Do not power law fit your process data for predictive models. No. Stop. Put the keyboard down. Your model will almost certainly fail to extrapolate beyond the training range. Instead, think for at least two seconds about the chemistry and the process, maybe review your kinetics textbook, and only then may you fit to a physics-based model for which you will determine proper statistical significance. Poor fit? Too bad, revise your assumptions or reconsider whether your “data” are really just noise.

Always run qNMR with an internal standard if you are using it to determine purity. And, as a corollary, do not ignore unidentified peaks. Yes, even if it “has always been that way”.

DOE models almost certainly tell you less than you think they do, especially when cross-terms are involved, or when the effects are categorical, or when running a fractional factorial design…

Maybe incorrect rebracketing? It’s supposed to be be-inhalten, not bein-halten. Otherwise maybe a writing style thing…

Me: you’ve been in the freezer for hours now, please freeze Supercooled water: how bout nah

Roughly a truncated cone with diameters ~7 nuts and ~9 nuts, and the cup is ~12 nuts high (loose guesses, it is hard to tell due perspective and nuts of different sizes). Throw in an extra layer to account for the heap at the top (which is a dome taller than 1 hazelnut, but treating it as a shorter but full layer should give some error cancellation) to give a height of 13. The volume of a truncated cone of those dimensions is ~657 cubic hazelnut diameters. Random sphere packing is 64% space-efficient (though wall effects should decrease this number) giving a total of 420 nuts (nice).

to management: Gonna give me $100K for a new GCMS compatible with a shiny new win11 workstation that MS will obsolete in a year or two? How about paying for a new license (subscription!) and a marked up PC and a technician visit to recalibrate everything for the $2MM NMR spectrometer? And then have IT come in to install their mandatory security software that bricks the instrument anyway? No? Then enough griping about your compliance numbers. If it bothers you that much, pitch a proper ask for capital to the business and get IT to allow us to just airgap the sucker instead of trying to debug some corporate security vendor’s rootkit.

Yes and no. No surface tension implies vanishing intermolecular forces, so the liquid would not be cohesive and would expand in all directions to the volume of the room… which is pretty much the definition of a gas. Not quite though: supercritical fluids also do this as long as temperature and pressure remain high enough, and are indeed useful in niche applications industrially.

Just think about all the shit you had to do to get from then to now, and then imagine that you have to do all of it all over again.

Pretty sure I just got anti-bribery ethics and compliance training that said no one in my company is allowed to accept such gifts lol

I’m not sure I’d call US sunscreens way worse (they are still very effective at blocking UVB, just not UVA as effectively), but there are definitely better options abroad. There definitely aren’t many options; that’s part of why Hawaii banning two common sunscreen ingredients for marine toxicity reasons was such a big deal.

Not saying that it’s necessarily a bad option, but my biggest issue with delta chat is that it does not offer forward secrecy (if a user’s private key is compromised, past messages can be revealed); Signal does. Delta no question beats signal in decentralization, though email is less decentralized than it seems–how many people do you know who still use gmail? Delta also inherently leaks metadata on whom you’re communicating with to the email host (that’s just imap/smtp). Signal can mitigate this somewhat with Sealed Sender (which gives one-way anonymity), though it can be broken with statistical analysis, and signal metadata is more identifying due to requiring a phone number.

FYI, while Threema front-end clients (apps) are open-source (and offer reproducible builds, which is surprisingly uncommon in open-source land), the server component, though supposedly audited, remains closed-source.

EDIT: for comparison, the Signal server code is mostly open source, but things like the spam filter are closed.

Back in my day there was an element called unununium until some nuclear scientists bismuth-munching paper-pushers with nickel allergies decided in 2004 that they liked Röntgen more than Regirock.

And before anyone checks, R/S were released in 2002 in Japan and 2003 internationally.

My vigour returned and in truth I thrived, and to think I take up sugar now! Banting and co shared a Nobel Prize and their work saved north’ard of a million lives, Nobel them all!

I was lost to cruel disease when a miracle cure saved mother her son. Dried her tears, now I’m a croakin’ man but I’ll never more fear the last of Banting’s imparted years!

For those who did a search only to get back pages of less-than-useless SEO slop that just recites the number line, here is something that better describes some of the grammatical insanity.

also, czterydzieści cztery is imo one of the less pronounceable words (well, two of them) in Polish.
