Last night I went to DigitalOcean and spun up a tiny new, $4/month droplet – on my own dime! It sounds crazy, but I’ve never actually wanted to pay for hosting myself before. But I have a fun little web app cooking up, one that might eventually pay that $4/month back with interests, and I decided, why not, it’s time to finally put some of my own skin in the game with this whole sysadmin thing....
Poking around in a fresh VM in Vagrant, I see bash dash, a POSIX compliant shell linked under sh python3, 3.11.2 at the time of writing awk, specifically mawk sed, if you count that (I do) perl, specifically Perl 5 There may be others I missed. Why I’m curious: Knowing that a language is installed by default on the most popular Linux distribution can simplify certain concerns considerably, which are of special interest to people who don’t work on Internet-connected boxes....

Two ways around this problem: Bite the bullet, and install the timers into /etc/systemd/. This means giving up chezmoi version control, making the overall system more snowflake-y. I’m not crazy about it. Remote in with tmux, instead of ever logging out, just use C-b d to detach from the session. I’m going with #2....
1 2 # ⚠️: Reboots your VM. su -c "$(whereis adduser | awk '{print $2}') $(whoami) sudo && $(whereis reboot | awk '{print $2}')" In all its glory! For Debian 10 and up, because Debian 10 is where the sysv to systemd conversion became totalizing. Let’s break down quickly why each part of this is needed: Since we are trying to add ourselves to the sudo group right now, we obviously can’t use sudo....
