I've updated my one stop system update script to remove unused Flatpaks. #linux #projects
RAM Usage Nerdery

Sander August 25, 2023 at 11:49 am
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.

Workaround for when poetry cannot find pyenv managed python

Sander June 16, 2023 at 11:23 am
I use pyenv to manage python versions for my projects, and use poetry to manage project dependencies. Poetry was unable to find the latest python version, and insisted on creating virtual envs with system python.

Setting poetry config virtualenvs.prefer-active-python true did not work for me, and neither did poetry env use whatever-version:
```
$ poetry env use 3.11
Could not find the python executable python3.11
```
However pyenv can list the the full path to the currently active python, which can be used as a parameter to poetry, so the following worked:
```
$ poetry env use $(pyenv which python)
$ poetry install; poetry run python --version
```
Update: double check that pyenv is configuring the shell correctly -- $HOME/.pyenv/shims should be in your PATH variable, and your shell runtime configuration file (such as .bashrc / .zshrc) should contain eval "$(pyenv init -)"

Hope this helps!

Ubuntu's minimal installation appears to be the standard installation plus the removal of some packages! That's unexpected as I was trying to save installation time. #ubuntu #technology #linux
Map Eject to Multitasking View

Sander April 4, 2023 at 1:55 pm

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.
