00:31 < EmmyNoether> New evidence shows that the key assumption made in the discovery of dark energy is in error
00:31 < maaku> TL;DR dark energy isn't real

00:59 < faceface> fenn: it's NMN everywhere these days
00:59 < faceface> thanks kanzure
00:59 < faceface> LeoTal: actually I'm more about the NMN NR than the nootropics

01:26 < fenn> faceface: why "mononucleotide" instead of "riboside"
01:27 < faceface> Sorry fenn there are two different products nicotinamide ribonucleotide (NR) and nicotinamide mononucleotide. They work differently
01:27 < faceface> I proabably got them confused before
01:27 < fenn> and why not just NAD?
01:28 < faceface> That's a different metabolite
01:28 < fenn> and why is this just now a thing? we've known about NAD for ages
01:29 < faceface> New studies of large doses in mice
01:29 < faceface> And probably just fasion
01:38 < fenn> ok so apparently nicotinamide riboside is patented and nicotinamid mononucleotide is (similar? equivalent?) but not patentable
01:39 < fenn> and something something "turns on sirtuin genes"
01:39 < fenn> i'm sure we all remember how that worked out with resveratrol

03:37 < adlai> maaku: thank you for that link! your tl;dr is possibly overconfident; i'd summarize the finding more cautiously, as: estimating locations of galaxies, distant both across space and through time, on the sole basis of one kind of standard candle, risks outputting garbage when the standard candle's behavior depends on an additional uncontrolled variable
03:42 < adlai> fenn: nicotine, often considered a nootropic, is probably addictive enough to count as dangerous; iiuc, nicotine is more addictive than the other common focus boosting substaces (caffeine, amphetamine, methylphenidate), although this is hearsay since i seem constitutionally immune to nicotine addiction (likely due to conditioning at a young age by anti-smoker parents)

03:52 < faceface> fenn I think the method of production is patented, not the compound
03:52 < faceface> (not sure though)

06:24 < maaku> adlai: the only evidence for accelerating expansion, dark energy, is the standard candle
06:25 < maaku> if it turns out that analysis was wrong, and the acceleration goes away if you correct the analysis, then there is absolutely no reason to think expansion of the universe is accelerating

09:18 < kanzure> why don't libraries have hard drives in their catalogs next to their books?
09:18 < kanzure> can a hard drive be given an ISBN
09:20 < kanzure> can you check out sdcards?

09:26 < kanzure> i guess i'll go ask the #code4lib people
09:33 < kanzure> first sale doctrine breaks this.
09:34 < nsh> ISBNs are canonical. who's going to assign the number to some random hdd
09:35 < nsh> whose contents could change arbitrarily
09:35 < nsh> i think i don't understand the question
09:35 < nsh> but you should definitely be able to check out 10,000 books on an SD card within seconds
09:35 < nsh> otherwise what's the point
09:36 < nsh> and by 10,000 books i mean of course anything
09:36 < nsh> (created specifically for common consumption)
09:36 < kanzure> the #code4lib people are telling me since digital books are not covered by the first sale doctrine, ebooks on an sdcard are considered illegal by US courts and libraries would be hosting stolen materials and thus be liable
09:37 < nsh> fuck2courts
09:37 < nsh> what was the last thing useful a court did for me, except save my life
