I've worked in security for decades and nobody has ever asked me about certifications. I know a guy with CISSP and he said it has been useful sometimes, but basically I wouldn't worry too much. Getting more involved with the security stuff where you work will give real experience which is likely more valuable.
This seems to be different and is geared towards directly looking after other humans. Hactivism as I'm used to the term, can often be technocratic.
It's nice as a dimmable bedside night light. I also used the Anduril flickery candle mode at a birthday event recently.
If this is for live disks or mirrors (not backup), LUKS is reasonable. Backup is different from mirroring since one of the things it protects you from is accidentally deleting files. If you delete a file from your main drive, it also disappears from the mirror drive, so mirrors are not backup. For encrypted backup, I've been using Borg backup which is quite well thought out, though confusing at first. The backups go on a remote server which is ok since they are all encrypted.
Voip call quality is terrible, it is near unusable over mobile data IME, it adds latency etc.
I guess an intermediate measure might be to make all your phone calls through a forwarding proxy (e.g. implemented with Twilio API) so that all the mobile carrier sees is that your phone calls all go to the same number. Similarly you'd give out a VOIP DID number that forwards to your mobile, so all your incoming calls would appear to come from the same number.
About a year ago I found Osmand near unusable. Maybe I should try it again. I currently use Organic Maps and it's pretty good, though it's missing a few basic features that are probably on a todo list. Also, some of its data is wrong. I expect Osmand uses the same wrong data. Unfortunately last time I hit an error, I had no internet, but will try again next time I'm there.
Usenet still exists, but needs revitalization. It might as well be us.
Find some interesting blogs and subscribe to those. The ones that don't try to churn out content every day are the best. They only post when they have something interesting.
I have altered the deal. Pray I do not alter it again. /Darthvader
