Wine32 on elementaryOS 7 or Ubuntu 22.04
x86 games, like Championship Manager 01/02, might not install on this OS which cannot install wine32 due to system conflicts. This means apps like Bottles (Wine wrapper) cannot select a working Wine version.
To get around this, install the PlayOnLinux flatpak, which has an option to change the current Wine version. This will let you pick x86 versions, which install wine32 inside the flatpak. After which the installer will run.
If you get prompted to insert the CD use this trick to copy the the files into a virtual CDROM

Tried 1Password for SSH keys and Git management (keys in 1Password, authentication via agent + desktop prompt before access, and 1Password must be running) and not a fan of more red tape around the SSH keys. Non-interactive processes just fail to use the key first-time round, so I ended up having to commonly do operations twice. Easy restore from a BackInTime backup. #security #linux

RAM Usage Nerdery
I've been wondering how much RAM I used on my 32GB Ubuntu derivative workstation, mainly used for web development using docker containers and light vm experimentation. Yes when I spotcheck with htop
I have enough RAM free, but do I actually need 32GB, when I'm in the market for a new device or an upgrade?
It turns out, yes I do ideally.
The setup
On startup I've been running this script to save the memory stats into a csv file:
#!/usr/bin/env bash
while true
do free | grep Mem | tr --squeeze-repeats ' ' ',' | tee --append ~/memory.csv
sleep 10
done
Today (after 15 days) I pulled the stats into a database and browsed it:
sqlite-utils insert /tmp/mem.db memory-stats memory.csv --csv
datasette /tmp/mem.db
Sorting by the available column shows that the lowest value I get is 11.9GB available to be freed.
The available column is the sum of the Free column plus the portions of the Buffers and Cache columns (or the Buff/cache column) that can be relinquished immediately. The Available column is an estimate, not an exact figure. https://www.howtogeek.com/456943/how-to-use-the-free-command-on-linux/#the-available-column
I think it's a reasonable measure. This system does not have zram memory compression enabled, that would help probably.
It has 4GB swap, I did not measure it's usage.
Hopefully this review helps for people who want to measure their own usage.

Map Eject to Multitasking View
So I use ElementaryOS and in version 7 you are no longer able to map just the Eject key. I like to map this to the Multitasking View (something like the macOS Expose).
The solution is to use the DConf Editor application and search for show-desktop
. ElementaryOS repurposes the show desktop to the multitasking view. Simply set the value to ['Eject']
Alternatively you can set the left-super key (windows/command) to the Multitasking View. This seems better supported.
