Open source updates

Apps, Javascript, Linux, SenCSs, Web, 27 September 2010, 3 minute read

It’s been a while since I’ve written about a bunch of my open source projects, but that doesn’t mean they’re not still being maintained. Trimage, Grafico, F.lux and SenCSs are all still actively worked on. Read on to find out what’s been happening with them.


When last written about, SenCSs was at version 0.7. We’re currently at version 0.8.1, with a bunch of vertical rhythm fixes, mostly for form elements, and added support for HTML5 elements. You can now add it to the list of “HTML5 CSS frameworks”. ;) Though, “framework” it is not, so I decided to just rename it to what it is: a Baseline.

F.lux for Ubuntu

After releasing F.lux for Ubuntu this summer, It went from 1.1.1 to 1.1.8 mostly improving stability and making different parts of the application (such as the preview button) work more like users expect. I’ve also been working on KDE/XFCE support, which was kind of finnicky due to the way I select the indicator applet icon. Version 1.1.9, which will be released soon, will hopefully bring this support. After that, it’s onward to 1.2, which will include the ‘turn off for an hour’ functionality.

After announcing Trimage in March of this year, I’ve gone from 1.0.0-beta to 1.0.5, with a slew of added functionality in between. I’ve gotten a lot of help from people such as Tarnay Kálmán and Thomas Lété in adding cool new functions. Here’s what has changed since 1.0.0:

A while ago I tried getting Trimage into Debian via debian-mentors. This was unfortunately a very opaque process and in the end no-one wanted to sponsor Trimage despite numerous changes to the build system. I’d still like to get Trimage into the main repositories, so if anyone wants to help me out, that would be greatly appreciated.

For 1.1, Paul is going to update the command line options and generally use his python-fu to improve stuff.

Announced at the beginning of this year, Grafico has seen a bunch of cool improvements. Within a week, Jan Paul Posma implemented stream graph functionality (after I mentioned the math was much too hard for me, ahem…). Since then, David Parry added stacked bar charts, Rémy Coutable greatly improved my hover code while Jaap van der Meer improved the control of text in the hovers, Menno van der Sman implemented an awesome axis-value algorithm and a lot of options have become much more customizable. Most charts now support negative values as well as positive values, and I’ve done a whole slew of bug fixes and speed improvements.

All in all, a whole bunch of work by a whole bunch of awesome people!
