On MacOS is UMT/Qemu.

Not so smart afterall, eh?

SELinux doesn’t help much when it comes to desktop apps. AFAIK it’s more geared towards server apps and its configuration is complicated. At least that’s my impression.

You are right, GPG signing is good as well. But in both cases you still have unsigned apps.

What security problems do you think package managers are vulnerable to? If the upstream repo is compromised all bets are off regardless of the system.

Yep. And in such case an antivirus software might come handy.

Even package managers are vulnerable to many security problems - can they guarantee that apps are not infected either directly or indirectly (through a library)? There is also flathub. Windows have also an option to verify apps through certificates which isn’t the case with Linux AFAIK. If you want to stay safe on Windows to some degree you can, but the real problem IMO is that Windows is hugely more used and run by less technical persons. 🤷‍♂️

Security: Linux doesn’t need antivirus, just don’t install infected software. Riiiight? Sorry, but this is silly.

From what I read so far, hardware key is just another way to decrypting, not the required. So it’s just a convenient method to avoid typing a (long) password and instead just few PIN chars. So, if somebody gets hold of password, can still decrypt the disk even without the hardware key. Not perfect, but still better than only password.

Yes, currently I’m using my brain for that and was thinking a security key such as Yubikey with touch requirement + PIN. But at least on Linux there is no support for that, or is it?

Edit: Ha, there actually is - https://mhdez.com/posts/unlocking-encrypted-linux-with-a-yubikey/

Where would you store it then?

Get off Android to … Android 🤪

There are some (many is really a stretch) but not available in many countries nor supported by many merchants.

We need Digital Euro yesterday.

You have some valid points. Yes, economical aspect is crap, countries should push laws demanding that producers guarantee recycling and/or state clear lifecycle of the battery (actually it should be applied to all products). Even still, there are companies that do recycle batteries for profit, so it’s not that absurd. But you miss the whole other aspect with different chemistries, many even harmless to the environment. You are focused only on current li-ion it seems which are not very network storage friendly anyway.

I think you are wrong then. First, even Li-ion batteries are recyclable to a huge amount, usually the problem is that different manufacturers pack them differently without any blueprint and then it’s much harder to recycle them. Then there are a ton of different chemistries with ones really harmless (i.e. using sodium instead of lithium) but they come with less energy density. Which isn’t that important when it comes to energy storage for the network purpose but it’s important when it comes to cars and portable electronic devices. Also different chemistries have different lifetime, i.e. LFP batteries have better durability and are less fire prone than the standard li-ion.

Sure, but even then we don’t have a solution today. It’s all in the fuzzy future.

Where do you have TWhs of batteries? As you said, both quantity and capacity matters, when lower capacity you need bigger battery which is harder to put somewhere.

Are you talking about batteries?

Yeah, that’s a step in correct direction, but can you guarantee that everybody can be powered 24/7 through renewables/batteries, specially during winter? Unless that’s the case you still need a shit-ton of non-renewable energy that’s coming either from fossil fuels or nuclear. And if you want to avoid (co2) emissions, then you need nuclear to cover everybody, and if you have nuclear then it has to run 100% 24/7. OTOH if you don’t have nuclear, you’ll emit all sort or crap during those periods. And so on. Also, it’s not just that batteries are sort of expensive, they are big. Also you are talking houses, but masses live in apartments where placing solar panels or batteries isn’t possible (at least in quantity).

What batteries exactly? The capacity required is huge.
