Are you a user of Astronoby, or you consider using it? I need your help to choose the next big feature to develop!
Here are 3 major features I’m considering:
- Earth satellite tracking and predictions
- Eclipses
- Comets and minor planets observation
Is there one that you’d love first?
Screenshot for Caelus' feature to set a custom time and date.
📣 New on Caelus: You can now use a custom time and use all the features for any date between 01/01/1900 and 01/01/2100.

Introducing Caelus, an open source astronomical dashboard dev.to/rhannequin/i...
"Il faut l’écrire en toutes lettres pour en réaliser la folie [...] : après trois défaites électorales, dont la dernière a mis ses soutiens en minorité à l’Assemblée nationale, et trois démissions gouvernementales, Macron a reconduit à Matignon l’homme qui venait d’en claquer la porte."
Check-out the release notes and stay tuned for new things soon!

It also adds multiple new attributes for solar system bodies like the phase angle, illuminated fraction, constellation or angular diameter.
Now a bit more about Astronoby v0.8.0.
It includes major performance improvements by introducing a LRU cache on expensive calculations. This enables to have calculations like rise and set or twilight much faster.
Astronoby v0.8.0 is out, and to celebrate it I wrote a blog post on how to calculate the best days for planetary observation!

With a few dozens lines my project is set up and with enough quality to go straight to production and receive early feedback. It's ready for features built on top with efficient CI and CD.
It didn't take long and it's super nice to be already sharable with the community.

- Want some easy styling helpers? Install TailwindCSS and it's ready for dev and prod.
- Presentation code duplication? Just use a helper.
- Code coverage? On a personal project?? Don't be that person, and with GitHub Actions set up by default it's so rewarding.
- Fast deployment? Use Kamal.
- Add a new sub-project to an existing application? Just use a namespace.
- Want to load something heavy only once for the entire app to access? Just use an initializer and a singleton.
- Want to support multiple locales? I18n is there and easy.
- Light/Dark mode toggle? Simple Stimulus controller.
Moment of appreciation of Rails yesterday as I started a new personal project.
Thanks to "omakase", it is easy and straightforward to start something with good practices by default.
🧵
Thanks to Guillaume Briday for this nice talk at Paris.rb that motivated me to deployed the latest Rails stack on a VPS with Kamal. www.youtube.com/watch?v=3-sS... 🇫🇷
Over the next few weeks I'm going to host more projects and content on a single server and domain. As usual, I'll do this in public and will try to document what I learn.

Tomorrow (or today depending on your time zone) is June's solstice. Did you know it's an instant and not a day? And did you know you can use this instant to find the Earth's axial tilt? Well, you can, in Ruby: dev.to/rhannequin/w...
Ephem v0.4.0 and it's all about performance!
Benchmarks show this new version is around 12 times faster than the previous one!
Using it alone is now incredibly performant, but it will also contribute to Astronoby's overall performance.

🚨 New Episode Alert 🚨
buff.ly/wRBddmV
A few days ago Stan and @rhannequin.bsky.social joined me to talk about working in legacy code.
What is legacy code?
How to work with legacy code?
Is legacy code inherently bad code?
Join us as they answer these questions and more!
@rhannequin.bsky.social talks about the Cosmos and using Ruby for Astronomy and Science!
Astronomy is often described as a visual science, but a purely visual approach to communicate it leaves out a significant part of the population. In this ESO blog post we talked with two experts to learn how we can do better with tactile activities.

Astronoby v0.7.0 is out! 🪐
I worked a lot on this new version that not only adds Solar System planets to the list of supported celestial bodies, but also introduces the use of ephemerides for outstanding precision.
I summarised the new features in this blog article: dev.to/rhannequin/a...
Ephem v0.3.0 is out!
It includes a huge improvement in the overall performance, better naming for the public API and some dependency bumps.

Le 7 avril dernier, la planète Uranus passait pile devant une étoile lointaine située à 400 années-lumière de nous

I shared some thoughts and ideas on how to deal with immutability and performance in Ruby.
The next version of Astronoby is coming soon and will have plenty of new features and objects. The documentation will live in the wiki and I already started to write the main pages.
Still some more work to do until the version is ready but you can already check on GitHub: github.com/rhannequin/a...
LLMs hallucinating nonexistent software packages with plausible names leads to a new malware vulnerability: "slopsquatting."
As always, any feedback is welcome!
The source code is on GitHub and the gem is downloadable using Bundler: gem install ephem
