> You don't need "run as administrator" for that. This is what makes it so doable since you don't need any privilege escalation. The reason why this is a big deal for a lot of people is your ssh keys will give you access to your git repos and other servers unless you have them password protected or use gpg/sk ssh keys which I think a lot of people don't do. And of course if you can see the known hosts file/bash_histo…

Plenty of dangerous things stored in `~/`, they don't even need password for ssh-key if there is ssh-agent running (this is in case of dangerous process running, not just upload). This is why I store keys on a hardware key that requires me to touch it when used and manually start ssh-agent when doing a lot of `git push`.

Yeah gpg/sk ssh keys are definitely the way to go.

Windows Defender is a long standing bug in the Windows operating system. ;) My impression is that its invention was for the sole purpose of eradicating the idea that Windows is insecure and prone to viruses, which explains why it can be overzealous and CPU hungry. I would only enable it for family members who don't know what they are doing. For some reason, I haven't needed any form of active virus scanning in someth…

Defender was invented to remove the need for other third part anti virus scanners that would do even worse intrusions in the system than the example in TFA, giving windows a bad rep.

Originally it was a lot less hostile, over the years now itself became the villain it tried to fight.

I just ran a test at https://browserbench.org/Speedometer2.1/ Firefox scored 89.5 ±1.7 Chromium scored 87.3 ±2.9 I guess that means Firefox did faster for those tests. I don't use Chrome or Chromium based browsers in general so I don't know how they compare in "feel". I am on Linux.

That's interesting. M1 Pro 8 core Safari: 133 Firefox: 221 Chromium: 339

Weird - Firefox seems about what I get but Safari and Chrome have always been within ~10% of each other for me on this test with an M1 and M2 (both straddling 450 if I run them right now). Extensions or power save at play maybe?
