Neither closed or open software is safer than the other in my opinion. If someone wants to find a vulnerability they will find a vulnerability. The only advantage open source maybe has that it’s harder to hide vulnerabilities for years and it’s more obvious if they don’t fix it. But personally I wouldn’t use open source just for safety reasons.

Even if you don’t buy a lottery ticket an infinite of you wins

For me it sounds like more like a PR move. It sounds like they just want people to adopt Oracle Linux because now it’s the good thing and when they’ll have the chance they’ll do the same thing. Not necessarily exactly what Red Hat (and IBM) did but something that won’t benefit the community but them. But maybe this is just my superstition or something and it won’t come to this. I hope it won’t come to this but I doubt it

Maybe check if your phone is stopping apps that are in the background. If I’m not mistaken it’s an Android feature and most of the time you can disable it in settings per app. On my Huawei phone it’s Settings > Apps > the app > power usage > launch settings.

I was using the ubuntu-drivers utility that this page mentions too but it turns out it isn’t working very much. Now I installed with the manual method from this page using apt install linux-modules-nvidia-${DRIVER_BRANCH}${SERVER}-${LINUX_FLAVOUR} and it’s working. Thank you for the suggestion!

Shows up in lspci. Booting a live OS would be a little bit tricky because it’s in a wall mounted rack but I will try that if nothing else works. Thank you.

Started with Bitwarden years ago, then I used 1password for a few months and now I’m using Keepassxc (Keepass2Android on my phone).

And I recommend everyone to use one. Not necessarily Keepass if they are not very tech savy (database synchronization can be a little bit tricky but not hard). Bitwarden was good too but Keepassxc supports adding ssh keys which is a big plus for me.
