  • not sure what they were alluding to, but my guess from first look was all the double bonds (represented by 2 lines parallel) on a single carbon, and those 2 double bonds being bent (i am not getting into sp carbon hybridisation, and specifically double double bond sp), but that is basically not possible (alost no amount of streic hinderance can do that).



  • the for most parts and intents is not really a good distinctintion. i did not go into details, mostly because it is a unrelated thing, but for most things, you can gradually transition from liquid phase to gas phase, without a proper transition. this is called a super critical fluid. consider like this, ice in solid form is not really “miscible” in liquid form. gasses and liquids of same stuff can mix. a






  • the unexpected. when i did some lab work in a course to study how different chain lengths travel at different speeds, that is what we got (shorter ones are slower iirc, because they interact more with surroundings, or maybe that is just true for chemical chromatography stuff). That was very interesting, cause i did that one with my seniors batch just because i was interested, and when it was time for my batch covid happened. also my first (major) exposure to carcinogen (we used some dye which is banned in eu i think)


  • fun fact, days have actually been getting longer pretty much since formation of earth (well moon to be correct). reason iirc is that moon is slowly moving away from earth, and this results in some dynamics changing and as a result earth spins slower. like billions of years ago, it was closer to 23 hours.

    ps - very rusty memory right now, should have skipped writing instead of half borked fact



  • From the reports that i have read (am indian), 20+ generics are expected, within roughly 2 months or so, with previous price being something along 10k INR (roughly 100USD) a month to about 3-4k INR (30-40 USD) a month. Drugs have always been kinda cheap here (as an example, a simple paracetamol (tylenol) tablet costs 1 INR (~1cent US)), so it is still expensive (for vast majority, it is more than 2-3 days of work), but much better. hope people use this cautiously though with reasonable expectations.

    it does. I have snap shotting set for every hour, so every hour my file system creates a copy my main canonical file tree, and if some files changed in that hour, other than those files, all files are mapped to canonical file entries (same block data). for changed files, it points to their original blocks, so essentially changed files have copies. now you can write a command to delete certain amount of old backups, or oldest or however many, and there are multiple graphical implementations as well.

    some example of snap shotting file systems are zfs and btrfs. in linux latter is better supported in general. zfs is a bsd project which has a openzfs implementation for linux and many distros support it too.

    how about a snapshot based system? snapshots treat all changes (inode level or in some deduplicating cases, block level) from some starting point, each snapshots only saves changes.

    I know every one will say snapshots are not backups, and i fully agree, but you can also implement a full mirror of relevant dirs in some external snapshot-ting file system on some other media, and like once a day or week or month, keep making snapshots.





  • for cookies, you can try to open devtools, and then go to network tab, and there find the pdf file, and then right click, and you will find an option something in lines of ‘copy as/for cURL’, copy that, and paste somewhere. repeat exercise for some other file. this should give you some pattern as for how to make a query. it most likely just needs a bearerauth/token in header cookie, or something alike that.
