Notepad++ is a fabulous software program that had no complete alternatives on Linux. I used it for scripting, text manipulation, note taking, dumping and editing thoughts. Scintilla-based equivalents Geany, SciTE exist, but do not come close.
Really? No alternatives on Linux? Have you tried Emacs? I think Emacs with Org mode blows Notepad++ out of the water in all the uses you just mentioned.
I self-host everything from my home network including my website. I like to keep all my data local. 😁
It's a simple setup: just a static site made with Lume, and served with Caddy. The attack surface is pretty small since it's just HTML and CSS files (no JavaScript).
First of all, doesn't Navidrome have authentication? So, I don't see why exposing it to the public is a problem.
Second, some reverse proxies support basic auth. This way, you can password-protect some services and is useful if the service does not have its own authentication. Here as an example snippet for Caddy:
Probably or probably not. The only way to find out is to try. I've installed RetroPie on a number of old laptops; the oldest one being a 2002 Toshiba laptop. I got to play GBA games just fine with it.
You can try turning it into a retro gaming station by installing RetroPie. Some have got it working on as little as a Pi Zero. Of course, that laptop won't be able to run the more demanding emulators.
If you need S3-compliant storage for testing and development, you can use an S3 mock server. I've tried the following for use in web development and CI environments, they are lightweight and configurable:
If you want a similar editor on Linux, then I suggest Kate. If Vim and Emacs didn't exist, I'd be using Kate.
