  • I have 2 lines of though to explain this, both going totally different ways.

    I am not a chemist, and polymeric science is arguably my worst. so take everything with lots of salt

    I do not know your sex (yes), but for the first one it maybe matters.

    Humans basiccaly have best perception of greens. we have 3 kinds of cones (color detecting cells) and it is basically blue and green and a little redder green (it effectively works as red detector), and we percieve much better granularity in green color spectrum. also those who are female at birth are better at this (some source that i remeber said something in line of 10x more colors observable by females than males). so it is possible all kinds of dyes degrade, and wwith greens you are better able to percieve it. this is in theory testable by perfectly caliberated camera and lighting and displays, and measuring the pl response (doable in a lab setup).

    more likely reason is dyes degrade. dyes are often organic (organic in sense of carbon containing) aromatic or more generally resonant structures designed to have absorption in specific ranges. the wavelengths they absorb the most, or reflect or transmit (as in allow it to pass) determines their colors. for example, our sun has peak emmision around green wavelengths, and life on earth evolved too roughly reject that (they absorb lower and higher wavelengths, if they absorb the most common, they probably die faster). if i remember correctly, organic dyes in paint often absorb the wavelength and then emit (resonance, the color being the resonant frequency) the light, so green dyes get the most common light (assuming the paint is applied on a surface recieving sunlight, if not, with leds for example, it is a bit bluer), and hence has a higher degradation rate. dyes degrade by general oxidation or any other chemical reaction, and that could also be possibly more likely on certain pigments as compared to others, and thegreen one just might be more reactive one. If pigment is inorganic, then it is whole different can of worms - whatstarting compound - lets say FeO (II), which may oxidise further (green -> brown) or something else.

    Without much to go by, there are just so many possibilities.

    basically any amount of energy conversion is lossy - a loose fabric stretching and pulling on frame in a “wider fashion”, and any deformation of frame will require a lot energy - all subracting from your fall. and fame up in your tushie is at worst a life long pain in sitting or in bowel moments, a direct fall is iinsta death from basically anything above, lets say, 10th floor (pulled number out of thin air, but assuming a roughly flat contact, and human not falling like a diver reducing the direct load o spine(by crushing their arms))









  • reason for them not appearing is that xmpp is a largely relaxed platform, that is, all implementations are not equally strict. some may implement certain extensions, others may implement other. encryption (omemo) is a common one that most implement, but then client (the user apps like gajim) may or may not implement them correctly, or they may have a fallback (first communication between 2 clients maybe is not encrypted), and other different problems with encryption being flaky (firstly, it is not perfect forward secrecy, it is a bit prone to failure (messages unable to decrypt), etc.), hence it is not recommended much.




  • If i am not wrong, it is the amount of time a piefed tab stays in focus. I tried to find it in cookies, but could not find it, but it is stored only on the user’s end (not on server). I have a few problemss with it (i can go do something else, while pifed tab stays focus (and browser does not unload it), it is still counting usage, but since they are not invasive, and not tracking when and how i am interacting, they can not do any better.








  • I seemingly have a rverse take - I much prefer the latter. i just do not use threadiverse, i use places where !/@ means something totally else (for example in programming ! is not and @ can be used for different purposes, but in my shell, @ sigil is used for arrays). the latter is very clear to me - /c/ is comm and /u/ is user. a bit more verbose (3 characters vs 1) but not that much but much more readable for someone comming from outside or who context switches.
