Gaia Sky hits version 0.800b

Today I'm releasing version 0.800b of the Gaia Sky, probably the last beta version before version one, which will come in late summer with GDR1 (Gaia data release 1).

This time around we bring on loads of improvements, bug fixes and new features. Check the comprehensive change log out:

The Gaia Sky is Gaia Image of the Week

The Gaia Sky software, former Gaia Sandbox, (and in particular its WebGL ports) has been chosen by ESA to be Gaia Image of the Week. The WebGL version includes a spinoff -called A Window to Gaia: The Focal Plane- which displays in real time the Tycho-2 stars that are being observed by Gaia. The WebGL ports have problems with mobile browsers and also with Safari, but they should work well with Google Chrome and Firefox (the former is significantly faster than the latter).

Here is the video which showcases the web applications:

Released the first beta version of the Gaia Sandbox!

Today we have published the first public BETA version (v0.703b) of the Gaia Sandbox, a real-time, 3D, astronomy visualisation application that runs on Linux, Windows and MacOSX systems. Its main purpose is to serve as an outreach platform to ESA's Gaia mission, and it is free (as in freedom and gratis). It is also open source under the LGPL, so go try it out!

The Gaia Sandbox is a real time simulation of Gaia, the Solar System and the Galaxy with advanced graphics and more than 100.000 stars to observe and navigate through. Here are some of its main features:

Physik in unserer Zeit reviews the Particle Physics Simulator

Physik in unserer Zeit

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.

Messing around with HTML5

Snake js HTML5

Hi there! I have been messing around with a snake game written in HTML5+js. A great deal of parameters can be modified in real time using an input form in the same page, such as the width and length of canvas, cell shape, background colour, food colour, snake colour and the speed of the game. Also, I posted the full javascript code.

If you are interested, you can check the results here.

Some photos of Nepal

Today I'd like to drop some photos of my recent holidays to Nepal here. All of these were taken using a Canon 40D with the Canon 28-105 USM II f3.5-4.5. I decided to leave my other two lenses home (the wide angle lens Sigma 10-20 1:4-5.6 EX DC HSM and the standard Canon EF 50mm f/1.8 Mk II) because of the philosophy of the travel. We were mostly a backpacker group and we'd be moving around quite a lot, trekking the Himalayas and going to the jungle, so I figured the extra weight wasn't worth it. Looking backwards, I regret not taking the wide angle lens, for some of the landscapes we could behold were truly amazing.

Also, I took a good bunch of pictures using my phone, the LG Nexus 4, you'll find some in the Flickr set too.
