  • can you do some tests?

    I hope you have some other machine (for example a phone).

    now download the same file on both devices (ideally do it for more than 1 file, and pick something which is static)(static here means file does not change. if for example you download a video from a site, and they encode all their streams live, there is possibility that file result is slightly different).

    now find hashes for both the files. i am not going to explain what is a hash here, but if you want a brief, imagine it being a unique id for each file.

    to find it, go to terminal and type

    md5sum <path> where path is the file path (to know the path, you can often just drag a file from your graphical file man manager into terminal and it should auto fill the path).

    this will produce a strange looking string.

    do this for file on both devices (if you are on a phone, this is hard. instead, you can try to copy to your linux desktop, preferably with a wired connection to reduce variables).

    if both hashes are same, the files are same. in this situation, your file viewer/player is broken. there are possibilities of your memory being bad or drivers being bad but these are miniscule.

    there is another possibility that your drive is either out of space, or out of inodes (something fancy, related to filesystem, not explaining that here). input/output error can often happen from such things. in this situation, best course of action is boot a live iso, and clean the disk (for example, if it is a btrfs partition, and it keeps making snapshots which are not cleaned properly, or some bad program keeps creating extremely tiny files, extremely fast).

    we need a lot more information if this is the case.

    if file hash is different, then it is simpler - either your downloader is borked (use a different browser, or use command line downloader, like wget/curl/aria2), or your disk is broken, or your file system is borked (something similar to above but more pronounced).

    changing browser/downloader fixes the problem - you are golden. if not, try swapping out the ssd, and reformat a fresh install.




  • ideally, os should not affect power supply. there is a potential that your os (well not os, but os having poor drivers causing hardware) drawing a lot of power, or possibly your system is unstable (in sense of frequently fluctuating power draw). If you think the os is to blame, find some stable taxxing benchmark (lets say ffmpeg transcode and run something for hours take a video, and then take some taxxing codec like av1 and write to /dev/null (so storage is not filled)). if the performance is stable (for ffmpeg transcode, it shows a speed parameter) and your power supply is not die-ing (i have at this moment forgotten how to spell present continous of die), then your power supply is fine, and your memory is fine too (another thing that shows abrupt behaviour). if performance is fluctuating or severely throttling, or something exotic, then maybe your setup has something broken. now swap some hardware or os, and replicate. you will likely find the problem.


  • i beg your pardon for following rudeness, but did you read the above message? I completely trust you that you tasted a mushroom and spat it, to live and tell the story to me, but what you are saying is that a certain mushroom requires a certain amount to kill a person. firstly i do not know how was that number found (as in ingestion or directly shooting it’s extract to blood). when you ingest, you do not absorb anything, and there is a potential that directly exposed will require a lesser critical dose. and beyond that - toxins do not require digestive pathways.

    the number is most likely calculated by measuring the amount present in a failed organ (in a dead patient mostly) and scaling to whole body and asking from surrounding folks how much they ate, and then matching with toxin concentration in mushroom. this lethal amount is not same for direct blood stream exposure.

    you possibly want to say something like - mushrooms do not have enough to kill you just from touch or chew/spit, but not will. will suggests that there is some specific reason that either mushrooms can not produce enoug toxin to kill you from touch.

    I would still stand by my original statment that it is stupid to expose contact or chew/spit. I am not saying you are stupid, I hav willingly tasted/sniffed many chemicals (not safe ones), but that is more of a decision (as in for learning purposes like you did for taste or for fun(that i do mostly)). It does not make that activity safe.

    sure, but was anything wrong in second paragraph?

    (following comment is long, so natural guess would be that i used a llm to write it - i did not. my poor structure sentence, grammar and spellings should indicate that. So please read it - if you are uninterested, skip the middle section and jump mostly from 3rd last para).

    since i clearly do not know mushrooms (or botany for that matter, i have studied biochem moostly at intro level, so that is about it), i looked up mushroom toxicity, and most websites roughly say ‘“generally safe” to touch, but don’t ingest and wash hands’. thing is, these guidelines are said for pretty much anything, since ingestion is the easiest way to go beyond our primary defense (skin). so i tried to look up mechanisms, and found the following article

    https://pmc.ncbi.nlm.nih.gov/articles/PMC11333700/

    so i am trying to find mechanisms of toxicity which do not specifically require digestion metabolic pathways (you have metabolic processes happening in all cells, so general oxidation and reduction do not count as ingestion specific, as that can happen from topical contact only).

    gyromitrin - ‘Toxicosis can result from oral and inhalation exposure.’ so likely getting into bloodstream from lungs. further processes require hydrolysis at low ph, so not happening in blood as is. but if we consider a small amount of hydrolysis, it can still form formaldehyde on oxidation.

    also

    ‘enzyme that is directly inhibited by gyromitrin is the pyridoxal phosphokinase. This enzyme is responsible for dietary vitamin B6 (pyridoxine) conversion into active pyridoxal 5-phosphate (Horowitz et al., 2024[53]). Moreover, in vitro and in vivo, MMH may generate hydrazones with pyridoxal-5-phosphate (Barceloux, 2008[8]). Pyridoxal-5-phosphate is a cofactor for glutamic acid decarboxylase and GABA transaminase in the gamma-aminobutyric acid (GABA) synthetic pathway, which results in decreased GABA synthesis (Barceloux, 2008[8]). MMH can directly block glutamic acid decarboxylase when given intraperitoneally to rats at a concentration of 0.8 mM/kg, resulting in a further decrease in GABA levels (Medina 1963[71]).’

    so gaba (for now, just consider it something required in brain for optimal signalling)(signalling refers to neuron activation here) is disturbed. this is a direct effect, no metabolic activity required.

    moving onto - ‘Orellanine is a potent nephrotoxin found in some species of the genus Cortinarius’. nephro means kidney here.

    Orellanine toxic pathway is not clear, but none of the proposed methods suggest metabolic pathways, and mostly go like after ingestion of so many grams, so and so amount is found concentrated in kidneys (and since the same compund is found, it mostly got absorbed into blood from intestines, and then filtered by blood.

    also ‘Orellanine disrupts LLC-PK1 cell monolayers and inhibits membrane-bound alkaline phosphatase and cytosolic lactate dehydrogenase activity’

    moving to Cyclopeptides - Phallotoxins and Amatoxins.

    ‘Amatoxins are able to inhibit mainly the activity of the RNA polymerase II (RNAP II) and also polymerase III (RNAP III), through α-amanitin and β-amanitin (respectively) (Diaz 2018[27]), resulting in decreases in mRNA content, causing deficient protein synthesis and cell death (Garcia et al., 2015[42]) (Figure 7(Fig. 7)).’

    ‘α-Amanitin has been shown to act synergistically with cytokines such as tumor necrosis factor-alpha (TNF-α) and this may be the final cause of liver failure.’

    then the article goes into antidotes.

    point being - all the toxic things (except partly the first one, which would be much slower in one of its pathways) do not require digestive metabolic pathways, just have to reach blood, and then time and amount is key.

    Should i say on stuff that I do not have knowledge about - no, mostly. my first comment was mostly written in humor, the way the parent commenter wrote. but then the asked about it in followup, and they guessed it was a joke too. but i still replied and gave a plausible reasoning for my comment, mostly because that is kinda how i like my humor (be at least partially based on reality, and then change it). could i have done a better job? sure, but I do not think i did a gross injustice. most comments that are written are not refering or citing reearch articles. I had heard of how some mushroom toxins work ( i had heard of nephro one sspecifically), so based my response on that. as to where i got that - i dont know, probably some youtube video.

    And finally - can you please turn down the sass just a notch. you seemingly were unhappy with my comment (possibly a seasoned forager, or a mushroom toxicology researcher), unhappy enough to downvote both comments. and someone also agreed with you, so they likely have similar knowledge i presume. given these facts, would you like to revisit your comment, or voting. If nothing, at least respond to this comment. I think my ego is fragile enough to reply to a single line comment with 500+ words just so i can say i was write, but i do not like being wrong.


  • i was trying to be funny. fill redact with paralyse or kill.

    I would not recommend chewing (and subsequent spitting) mostly because you do not know (of the top of your head) about the toxic dosage, and it may enter your blood (where if it enters, game over i guess). think some amount of exposed area near your gums, or micro-scissions. Same with picking, maybe you cut your nails recently and have exposed skin (blood will likely help by clottong and blocking) or while foraging, you ran next to a sharp branch or bark and have a deep scratch exposing blood. not likely stuff.

    also i do not know much about mushrooms, and likely their toxic nature is completely different from stuff like ivies (poison ivy for example) where just contact on exposed skin can cause immune response (swelling, itching, etc), but maybe (possibly) some mushrooms would have some toxic thing on surface.



  • Well I do not collect anything because I am broke. But I had some old stuff (pirated cds from ye olde days before streaming was mainstream), and suggest to rip the cd contents to some modern storage (portable ssd or hard disk, or some other kind of storage), mostly because that way they do not take physical space (you can give the cd away to someone who may find it useful), and digital copy can have multiple backups and less likely to age poorly (think cd getting read errors as more scratches forms from usage).


  • Imo the best method is to make a detailed post, and have it pinned, and have a summary in sidebar linking to post. if community is on piefed, you can keep detailed in wiki, and have a pinned post and sidebar both have summaries. I am a rss feed user, and a pinned post helps there (it will likely be the oldest post that will always be served)







  • I played almost excusively on mobile back then (my parent’s or sister’s mobile, until I got big enough to get their phone as they switched)(that is how it should be imo).

    snake game on feature phones

    Clash of clans (when i left, third guardian was just added, and town hall 11/12 was the highest and I left around 9).

    subway surfers (played it a lot)

    paper toss (not that much, but i guess enough to remember)

    hill climb racing (1 and 2) (i think i completed 1 completely)(completed in sense of bought all vehicles and maps) and 2 a little. I recently reinstalled them, and 2 is just not it anymore, 1 is still fun if played offline.

    a lot of pokemon and rom hacks, for about 2-3 years
