this website covers heat and cold pretty well in my opinion: https://www.jameswebbdiscovery.com/satellite-technology/heat-management-in-satellites-techniques-for-dissipating-heat-in-space

since radiating heat is the only real way of getting rid of heat, the main solutions are limited size and power combined with insulation. quite opposite to what datacenters do.

most people can get behind parental control. that is why bad actors are pushing for age verification everywhere nowadays.

i think the issue many people have with that field is, that it enables bad actors to do things. all the while, it does not really do the thing it is supposed to do: if i trust my kid with sudo, the field can easily be altered. if i do not trust my kid with sudo, it cannot install anything either way.

with your last paragraph i (and probably most people) agree. but we already have those tools, right? at least until i knew computers better than my parents, there was no way i could install anything without them being OK with it. even when i was admin on my very own desktop, i was heavily reliant on the parents for everything costing money. yes, even my dumb ass figured out how to pirate stuff. but to do that while being afraid to brick your precious device with some virus - you need some tech literacy, which is for sure beyond changing one value.

who and what is your threat model? as @[email protected] pointed out this article was probably rather accurate.

if you just want to browse anonymously - it is likely, that even the biggest tech corpos can’t de-anonymise you.

if you do small time crime, like buying and selling contraband - likely law enforcement would try to catch you in the real world. you have more vertices and vulnerabilities there, different enforcement agencies are experienced exploiting these.

if you paint a big ass target on your back and get the interest of the CIA or similar - you are probably fucked one way or the other. they may have the ability to de-anonymise you. but if you listen to people that did get caught or do the catching (e.g: darknet diaries), most of the times it is a small mistake. if you only ever play defence, that is enough to loose the game. but what are your options if your adversary is a national agency?

why would anyone spend time to disprove mediums (if not for the fun of it)? like anything in science I have to prove MY hypothesis. so if a medium wants to claim what they are doing is actually ghosts, the burden of prove is on them.

i would claim, that a reasonable person would attribute the medium (not a ghost summoned by the medium), if they are seeing things, hearing things, whatever a medium does… while they are in the room with that medium person. again, the medium needs to prove anything happening is not just them messing around. i guess they could put some LSD into my coffee before leaving and make me see things alone. but i am pretty sure the LSD would be detectable and the person responsible for drugging me arrested.

a medium and other trickery cannot be used as explanation for those people who experienced the third man factor. while it is totally OK for you or anybody to say “{…}, and that’s where I would stop, I can’t explain it, I don’t know what this is.”. the scientific approach would be to form a hypothesis, and start doing experiments to either prove or disprove the hypothesis. the problem is, that i cannot think of an ethical way to do such experiments. which is why, i don’t believe we will be able to prove or disprove such a thing. so let’s go with Occam’s razor and prefer the explanation where people hallucinate things, due to body and mind being pushed beyond limits.

mediums are a completely different thing, as they peddle a ‘wonder product’. claiming things without proof and asking for money. but that modus operandi is not restricted to non-science. radioactive underware was a thing…

i am talking about people who did experience something and how they choose to interprete that experience for themselves. if you ask me, it was most likely their body and mind being pushed across certain borders - which made them feel things that where not actually there. if you asked me about my grandfather, i would tell you that he is most likely not here or there and it is just my imagination. but it gives me a little bit of comfort to at least allow the possibility that he is somewhere.

those are all personal choices about personal experiences, which do not affect anybody. but if someone start selling a product or even a religion. they crossed a line and are (trying) to affect other people.

it is not irrational, to observe (or experience) something and not being able to explain it.

i do not have any reason to assume my friend is a liar. so she heard her fathers voice. how or why she heard it we will never know, as she was not hooked up to a brainwave scanner or similar.

apparently we have different people from different times having experienced similar things. thanks @[email protected] for pointing to the Third Man Factor! so i would say it is quite reasonable to believe something can happen to us humans in extreme situations. is it just our imagination? quite possible! especially considering the more extreme stories mentioned in the wikipedia page surely drove those people to or past their individual limits. but that brings me back to my last paragraph: it doesn’t change anything or even matter. those voices, or whatever they where helped those people survive extreme situations and live to tell the tale. whether it was a deceased loved one, a valkyrie from norse mythology, friendly tree spirit, their subconsciousness wanting to survive, … or just hallucination due to thirst/starvation/exhaustion.

the effects didn’t change. so whatever the cause is, shouldn’t change my, your, or anybody else’s life

thanks! didn’t know there is a name for it

ghosts are like religion: can neither be proven nor disprofen. what do you even consider a ghost? i do faintly believe in spirits:

when i am sitting at the grave of my grandfather, it does feel as he is around somehow. is that because i miss him and wish he is still with us? likely…

a friend of mine recently lost her father. they are both accomplished mountaineers. on a solo tour, she told me, she heared her father’s voice reminding her to be careful - while not paying attention during a dangerous passage. was it her father reaching out? was it her subconsciousness taking the persona of the father? we will never know…

in the end it doesn’t matter in the slightest, what these feelings of ghosts or spirits really are. if our ancestors keep watching out for us, that is great. if our subconsciousness keeps watching out for us, while taking on different personas, that is great. life goes on the same - even if it all was just imagination.

what is the reason to put that tool into a browser? if i use the thing on my private computer, it increases complexity compared to a local installation (not an issue for many ppl here, but for my grandma surely). if i use it on a corporate environment, wouldn’t more employees use it if it was the default PDF viewer on their managed device?

what did i miss?

clamAV has heuristic capabilities. just search through the documentation and see how many switches contain ‘heuristic’:

https://docs.clamav.net/manual/Development/libclamav.html

I like to consider myself part of the exclusive and oh so elite club of linux users. everyone here saying that AV is not needed, because the best security is not to be stupid, is right. but is your grandma tech literate enough to not do stupid things on her computer? your teenage son?

as the linux user base grows, the platform becomes more interesting of a target. even for stupid attacks. and lets be honnest: lots of legitimate open source projects still use an install script to curl and pipe into the terminal as a suggested method to install. which is just horrible!

while an anti malware is a patch. it is the last line of defense after a stupid mistake. so it would be great to have an actual desktop AV for linux. eset used to sell one but it is long out of service.

i use clamAV. but i maintain it for the family, so it is not as simple as telling them exactly what to install and run with default configs.

anyway, for those interested: here are two videos of malware attacks against lunux in rather different fashions:

• https://odysee.com/@AlphaNerd:8/desktop-linux-is-under-attack:a
• https://www.youtube.com/watch?v=fNWPODkEHSA

again displaying, that DRM only hurts legitimate users. a pirate has never had the problem of backing up, moving or sharing his library…

i guess there is pixelfed. but i would compare it more to instagram. many lemmy instances allow uploading pictures directly, so you dont necessarily need a separate host.

but where i see the biggest caveat, is costs. cloud storage is not cheap and pictures are extremely large compared to text. therefore some lemmy instances only keep uploaded pics for a certain amount of time.

I dont know whether imgur is keeping pictures for ever or not… so i am not sure if it federated imgur would solve the ‘amnesia issue’ of some lemmy instances.

exactly what i am talking about. age restriction at the physical store kept you away for a while, while not forcing an alternative/underground market. however, if you knew the only way to get it is on an alternative store - you would immediately have looked there.

if you can run a private server, you can get rid of all ‘phone home’ requirements.

so you just need a cracked copy of the game itself. luckily it is completely legal to remove digital locks on anything you bought in many countries (not the usa though).

age verification is just a BS strawman. do you remember when we where young? we would access stuff and find ways to buy stuff. but whenever there was a reasonable but fair gap, it would be much harder to get whatever we wanted: buying weed was so much easier, than buying alcohol (without the appropriate age).

pirating is easy (even i figured it out before having enough money to buy movies & games). so the kids will just pirate that stuff and get their way anyway. age verification at the store makes so much more sense. sure, there are ways to circumvent those. but it is a reasonable stop block.
