GitHub to GitLab

I’ll shortly be moving the Gaia Sky repository from GitHub to GitLab (link here) due to the former being acquired by Microsoft. If you have cloned the repository and wonder how to update your remote reference, here’s what to do: $ cd path/to/gaiasky $ git remote set-url origin That’s all it takes. All pulls from now on should be directed to the gitlab repo.

Moving to Hugo

Bye bye paid web hosting + Drupal, hello GitLab + Hugo

Hugo SSG

The idea of ditching both my web hosting provider and Drupal has been at the back of my mind for a few months.

Bear with me. Since about 2011 I have been maintaining this website using the cheapest hosting tier my hosting offers – At least it was the cheapest at the time I got it. They call it The Essential and it costs over 300 bucks for 2 years. It is not a lot, but it is definitely too much for my purposes of hosting a small blog where I provide occasional updates on my projects, my portfolio and my CV.

Also, loading times are horribly long and the complexity of managing the Drupal installation (upgrades/updates) and also the database takes way too much of my time. Only the thought of updating to Drupal 8 sends shivers down my spine and ultimately got me searching for better options.

Review of Particle Physics Simulator

Physik in unserer Zeit reviews the Particle Physics Simulator

Turns out the German physics educational journal Physik in unserer Zeit (Physics in our time) published a thorough review of one of my Android apps, the Particle Physics Simulator back in January 2014. One of the authors of the article, Jan-Philipp Burde, contacted me a while back to let me know that he was preparing the article and to ask some information on how the code works, which I gladly provided. Then, he kindly contacted me again when the article was published in the January 2014 issue of the journal.

For what I could understand with my still basic German, the article talks about how the app can aid in the teaching of gas dynamics, providing some hints on the configuration set-up (no gravity, elastic collisions, etc.) in order to simulate a gas. For example, it teaches how to illustrate the concept of Brownian motion, removing the gravity and creating several small-sized particles along with one or two big-sized particles.

From Slick to Libgdx

A migration story

A couple of posts ago I mentioned I would write a few lines about my experience with the migration of my RTS engine from Slick to libgdx and that’s what I’ll do in this post. I’ll be talking very lightly on some issues such as the code structure, the rendering process, the camera, etc. If you need a starting tutorial please refer to the official documentation, this is not what you are looking for. I’m just trying to give my impressions in the migration process I had to undertake. But first I want to back up a little and give a quick overview of both libraries.

Old and new web designs

As you may have noted, I updated the look and feel of the website to a more sober, greenish and polished design. The moon in the header has been replaced by a jumping monkey, which is always likeable. Regarding performance, this new site has less and smaller CSS files and less images and therefore it loads faster. Additionally, it uses HTML5, which is good. I also took the opportunity to update to the latest version of drupal and make use of the newer ZEN base theme. Here there’s a side-by-side comparison between the old and the new styles.
