**Log 06: August 18th, 2025 - Hacking. And More Hacking. 🧑‍💻**

As I mentioned in the last post, we are now mostly back to the world of software. At this stage, I realize the following will probably make sense to make:

- A package for OpenMeteo.jl – this is already started but hasn’t been polished yet
- A package for [timewarrior](https://timewarrior.net) – I have scraps of code for this, but nothing package worthy yet
- A package for [todo.txt](https://github.com/todotxt/todo.txt) – some small scraps here and there but nothing I am satisfied with as a package yet
- Definitely a JinkiesComponents.jl package; I’ll probably have JinkiesComponents depend entirely on extensions with some basic functionality

Otherwise, this dashboard is now rapidly becoming quite useful actually. I am in the process at my home to get this dashboard running 24/7 so I can start using it for regular check-ins. Some more things I am beginning to think about:

- How do I use DaemonMode.jl by @dmolina to trigger a script in the background of my Pi every hour? Does it work like a cron job?
- Does anybody know how to do 3D modeling on Linux? Can anyone suggest me some tools? Maybe @sjkelly ?
- What are good fonts for displaying on an eink display? Maybe @cormullion has some thoughts?

At some point, this hobby project switched from, “Oh this is just a little fun screwball code project” to “Oh, I’d quite like this up and running as soon as possible; I want it!” Pretty neat to see the feeling evolve. Finally, here is a photo of current progress:

The calendar is a bit garish so I am thinking about how to either make that more compact or… Something! Also the timewarrior plot (thanks for the help @sdanisch in [Time-Axis Linked Bar Plot with Gaps](https://discourse.julialang.org/t/time-axis-linked-bar-plot-with-gaps/131632) and inspiration James Howard) somehow lost the bottom line of the plot box. This is not a Makie.jl bug but an e-ink resolution issue… That I will fix. At some point.
