Z should be inverted in the top picture.

I don't get why these kind of post crop up so often.

The answer to them doesn't matter and these aren't really math questions, because there is no context given. This is just endless discussions about different people having different assumptions on notation used there...

In real math, where the numbers mean something, good and consistent notation is important, but not necessary, because the order of operations or what those operations are exactly would be clear through the context of these formulas. Good notation just makes it easier to spot errors, work with formulas or to avoid confusion.

Here is what I would assume this formula could mean. Someone has 2 apples and 5 bags of apples that initially came with 8 apples each inside, but someone else ate 5 apples from each of these bags.

With this context it is pretty clear what the answer would be.

SELinux protects systems from bugs in software. Not against users with full root privileges using their own hardware.

As long as Valve is committed to an open system, without locked down bootloader like on mobile phones, it is unlikely that kernel-level anti-cheat can be implemented.

But that also means Steam Machines are unlikely to support 4K streaming from Nextflix and co. because also DRM will also only be on the level of other Linux systems.

True. But most good stuff isn't a solution for everyone. It takes real effort to escape vendor-lockin. Bigtech made sure of that.

If something is too simple to set up or requires no set up, or comes from a for-profit company, but doesn't cost anything, then it always suspicious.

I am just saying that the issue is not with passkey itself, but the individual implementations and that google/twitter/etc. is pushed towards regular users.

Critiquing passkey because vendor-lockin is like critiquing HTML for allowing ads.

True. But I would say that this isn't an issue intrinsic with passkey. Many people don't have time/energy or the attitude to think critically about technology and are herded towards Google/X-corp/etc with offers of convenience and because they are often the only offered choice on the web sites. But from the POV of passkey they just act as a password manager.

I use them with bitwarden and a self hosted vaultwarden. If my phone breaks, no issue. If my server breaks, I got local backups.... Keys are stored encrypted in a postgres database for which I have access, if I need to restore it. No lock-in issue or risk of loosing access when one or two devices break.

A better, well defined API for password managers to insert login information to the site compared to text boxes.

I self host vaultwarden, and use bitwarden clients everywhere. Passkeys are stored there

Passkeys to me, are a better way to insert login information. Some developers don't think of passwords getting automatically filled in, so this autofill sometimes breaks. Passkeys might be a improved interface to integrate password managers. Also, sometimes 2FA keys from my bitwarden client gets copied into the clipboard, which sometimes overwrites the stuff I wanted to preserve in there. This does not happen with passkeys.

I store the passkeys in my self hosted vaultwarden, they are a good replacement for auto inserting random passwords via text boxes.

You can? At least I do that. I host vaultwarden myself and store the passkeys there.

Passkeys to me are just a better way to autofill in login data.

Na. Even privatly traded companies can enshittify when it gets inherited to people not sharing the same vision as the one that made the company successful.

If you want to prevent enshittification more long term, convert it to a non-profit cooperative, with a work ethic that promotes providing the best service over short term profit.
