Volunteering at Devoxx

Updated the command line prompt to ⚓ Starship.rs due to an ⚓ issue with Powerline10k.

Starship works very well and is fairly simple to configure using a ~/.config/starship.toml file. There is a 🌐 Catppuccin Powerline Preset (theme) that was customised to move some information onto the right-hand side of the prompt and tweaked some of the default Catppuccin Mocha colors.

Practicalli Customisation of catppuccin-powerline preset

MkDocs is used for all Practicalli websites and something has changed so that ⚓ running a local website fails to build. This does make using MkDocs a little more fiddly to use. If I dont use embedded files in a code block then everything seems okay again.

This week I have been volunteering at ⚓ Devoxx UK in London. Tuesday was setting up activates for the event, such as building video game cabinets. Wednesday and Thursday was room monitor, ensuring the speakers and attendees are taken care of. The room monitor also captures feedback about the event back to the conference organisers (so they can continue optimising the conference for next year).

Linux shell hangingλ︎

After a package upgrade on Debian Linux today the shell was hanging when running both Gnome terminal and Kitty terminal.

A little searching and thinking the root cause was the nordvpn package conflicting with the Powerline10k shell prompt theme.

Removing the ~/.zshrc symbolic link removed the conflict as it was no longer loading the Powerline10k theme. Unfortunately that also stopped all the other Zsh features I used from Prezto

The 🎫 issue was reported via the Powerline10k repository.

As I no longer use NordVPN service, I removed the nordvpn package.

apt remove --purge nordvpn

Starship command prompt themeλ︎

A notice was added to the Powerline10k repository saying that the project is no longer actively maintained. As there is also an issue with NordVPN, then its time to try another theme.

A good friend suggested 🌐 Starship as an alternative.

The default theme was a little simplistic for me although there are several alternative 'presets'. As I am now using the Catppuccin theme for the Kitty terminal and was using Powerline10k as the command prompt, then 🌐 Catppuccin Powerline Preset seems to be the ideal choice.

Starship Debian Linux package install

apt install starship

The powerline10k theme was removed from the Prezto configuration, not setting any theme (otherwise starship does not show).

Add the starship init script at the end of the .zshrc file

Starship init script for zsh

shell title=`~/.zshrc` eval "$(starship init zsh)"

There is a configuration to generate the .toml configuration file for the catppuccin-powerline preset, but this didnt not find the theme (perhaps the Debian Linux package is not new enough).

Generate Starship config file using catppuccin-powerline preset

starship preset catppuccin-powerline -o ~/.config/starship.toml

Output: generate starship config file

❯ starship preset catppuccin-powerline -o ~/.config/starship.toml
error: invalid value 'catppuccin-powerline' for '[NAME]'
  [possible values: bracketed-segments, gruvbox-rainbow, jetpack, nerd-font-symbols, no-empty-icons, no-nerd-font, no-runtime-versions, pastel-powerline, plain-text-symbols, pure-preset, tokyo-night]

For more information, try '--help'.

NOTE:
    passed arguments: ["preset", "catppuccin-powerline", "-o", "/home/practicalli/.config/starship.toml"]

The web page has a link to the .toml file for the catppuccin-powerline preset, but the link is broken 🔗

A search on the GitHub repo found the catppuccin-powerline.toml file. This was copied to ~/.config/starship.toml file.

Opening a new terminal session in Kitty used the catppuccin-powerline preset and it looks quite nice.

Starship command line theme with catppuccin-powerline preset

Customise catppuccin themeλ︎

Unlike powerline10k which splits less important information to the right-hand side of the prompt, Starship has all the elements from the left-hand side. This makes for potentially quite long prompt.

format controls the layout of the prompt. right_format was added, moving the command duration, time, username and operating system details here from the left-hand side.

Custom Command Line prompt layout 
"$schema" = 'https://starship.rs/config-schema.json'

format = """

continuation_prompt = '▶▶ '

Component styles had the colors tweaked using the existing definitions in [palettes.catppuccin_mocha]

MkDocs issuesλ︎

After a package update apt update && apt upgrade I have some issues when running a local server for this journal, created with Material for MkDocs.

The same issue occurred once during the Continuous Integration workflow to build the site.

The issue seems to be intermittent and could be a simple issue of the local server being hammered too much.

I will keep testing to see if this is a short-term blip or a more serious issue. I didn't see relative issues or pull requests on the mkdocs-material repository.

Update on Error 429

Several embedded files were causing errors in the Journal website when using mkdocs serve. This is happening on other computers so the actual cause is not that easy to track.

The short-team solution is to replace any of those embedded file code blocks with the actual content of the files.

Updating the footer in 3rd Feb post fixed that issue. Updating %practicalli to #practicalli fixed the link.

I assume that MkDocs local server is better and finding issues in the text now and picking up on issues that I have not noticed previously.

After fixing those issues, I experienced a further issue

Devoxx UKλ︎

Devoxx UK 2025 banner

It was very rewarding and enjoyable to volunteer for Devoxx UK this year. It has been many years since I was involved due to my health challenges, but it felt very natural and familiar.

On Tuesday I helped build the cabinets for video arcade games although I didnt get chance to play as there were many other setup tasks.

Wednesday and Thursday afternoons I was a room monitor, ensuring the speakers had everything they needed and that attendees were in the right talks.

In the mornings I took the opportunity to watch some great talks and catch up with friends I had not seen face to face in a long time.

On Friday afternoon I was on registration desk and since it was almost the end of the conference it was mainly reprinting or fixing badges and collecting lanyards for recycling for those leaving a little early. I also packed up the registration desk and actually started planning that straight away so it took very little time to do at the end of the day. I have almost everything packed a couple of hours before the end of my shift.

Before I left I helped out with packing up the sponsor area and arranged space in the loading bay for one of the sponsors who had been let down by the courier.

Favourite talksλ︎

  • Disney Driven Development
  • Beyond Inspiration: Turning Learning into Action
  • The history of Computer Art
  • Demoscene: The Golden Years showing graphic demos made on early home computers
  • Reading Code
  • Understanding probabilistic data structures with 112,092 UFO Sightings
  • Application Security - Consistency is everything
  • Writing Greener Software Even When You Are Stuck On-Prem

There were more on Friday but I havent had time to add them.

Thank you.
