Maybe try programming? It's incredibly exciting once you get the hang of it. It can be frustrating at times but it's really rewarding. Since becoming my hobby/job its given me an endless source of things to do at home. Plus it can open up new career paths :)

mpd + ncmpcpp

Yes! Awk is great, I use it all the time for text processing problems that are beyond the scope of normal filters but aren't worth writing a whole program for. It's pretty versatile, and you can split expressions up and chain them together when they get too complicated. Try piping the output into sh sometime. It can be messy though and my awk programs tend to be write-only

I usually use Awk to do the heavy lifting within my Bash scripts (e.g. arg parsing, filtering, stream transformation), or I'll embed a Node.JS script for anything more advanced. In some cases, I'll use eval to process generated bash syntax, or I'll pipe into sh (which can be a good way to set up multiprocessing). I've also wanted to try zx, but I generally just stick to inlining since it saves a dependency.

I use LUKS-encrypted LVM volumes to store everything (and transfer via SSH or HTTPS), but would use GPG if I needed to encrypt individual files.

I've been using it for years and I think it's great. Currently on a 6 Pro. It's true that some apps don't work without Google Play services, but GrapheneOS has the option to install the google stuff in a sandbox, so you shouldn't run into any issues if you do that. Personally, I don't use Play services unless I need to, and use Aurora store for any apps that aren't on F-Droid.

In any case, you can always revert to stock or try another OS

Edit: as faede has pointed out, it appears that Google Wallet has issues. Also, the usage docs mention issues with banking apps in general, so that's something to consider

For vegetables I throw everything into a big stew with a lot of different things (kale, broccoli, cauliflower, onion, potato, mushrooms, tofu, garlic, beans), lots of hot sauce, seasoning, olive oil, etc. and eat the same thing every day, for the most part. I don't eat enough fruit but I do have a handful of dried fruit with oats every day

I would look into Gentoo's Hardened + SELinux profile if you want good security in a standard system, but as others have mentioned QubesOS is probably the most secure option OOTB (but it is very limiting). SELinux is pretty difficult to use but it's really effective, and there is good information about it on the Gentoo wiki. Not sure what exactly goes into their hardened profile but I know it implements at least some of the suggestions listed on that site (like hardened compilation flags). Also it's probably more vulnerable to 0-day attacks than Qubes, since it uses up-to-date software. But it's really flexible, and learning SELinux is useful

I learned by watching a bunch of cppcon videos, reading cppreference, and writing a lot of programs. Learning how to understand the error messages is also really important

As a Vim/NeoVim user my number one reason is speed. There's a pretty steep learning curve, but it doesn't take long to see noticeable improvements.

Aside from terminal applications generally running faster than GUI ones, there is a tremendous amount of flexibility that it offers when it comes to actual text editing. For example, you learn how to type things like ~~_f(vi(cfoo~~ _f(ci(foo^†^ which goes to the beginning of the line, finds the first open parens, selects everything inside of the parens expression, then replaces that text with "foo". After a while these kinds of inputs become second nature, and you can start using them to construct macros on the fly that can be applied to different places in your code.

One major downside is that it can take some configuration to get working the way you want it, especially if you want an IDE-like environment. NeoVim comes with a built-in LSP interface, which I've been able to get working pretty well for all of the languages that I use the most, but it's still kind of a pain to configure.

I'm sure Emacs is similar, but I've never used it. I don't think many people use Nano unless they need to edit something in a terminal but don't know how to use Vim. On that note, being comfortable with a terminal editor means that you'll have no problem if you're SSH-ing into a server or using the TTY console.

^†^ _f(ci(foo avoids an unnecessary mode change, see comment below

Congrats! It's great software. OsmAnd~, Unexpected Keyboard, ~~OpenLauncher~~, Arcticons Dark, UntrackMe, and Mull are a few of my favorites. Aurora Store also, but I try not to use it unless I absoutely need to (I don't have sandboxed Google services/Play installed)

Edit: OpenLauncher might be a bit out of date. Will switch to Discreet Launcher for now, but the dev has stopped adding features and will only release bugfixes and Android compatibility updates moving forward

It's great for anything low bandwidth that isn't tied to your identity, and helps for peace of mind, despite its issues. You do run into captcha or DDOS protection issues occasionally, but the new tor circuit for this site button sometimes works. Also it uses letterboxing to prevent resolution-based fingerprinting, which isn't very pretty, but leaving it at its default size (or locking the size using the WM) works well and is good for privacy.
