We previously posted about the clock app’s new look and today we are getting to know one of the developers behind the clock ( as well as other community apps.)  Bartosz Kosiorek gives us a glimpse into developing for Ubuntu and how he got started.

1) First, can you give us a bit of background about yourself and tell us how you started developing for Ubuntu?

My name is Bartosz and I’m from Poland. Currently I’m the developer for the Ubuntu Clock and Ubuntu Calculator. I started contributing to Ubuntu in 2008, by submitting bug reports into launchpad and fixing translations. Later I participated in the One Hundred Papercuts project. I made SRU verifications and eventually started developing.

My adventure with Ubuntu started from Ubuntu 8.10 (Interpid Idex). Previously I tried many different distributions (Debian, Fedora, SuSE etc.). I chose Ubuntu because it is easy to use and after installation, I have fully functional system. I like that after Ubuntu is installed, there are no duplicate applications and those already installed work perfectly with the system.

2) How long have you been working on the Clock and Calculator? How did you get involved in these projects?

I started to develop for Ubuntu about two years ago when I first heard about Ubuntu Touch and convergence. I started by contributing to Ubuntu Core Apps by testing, submitting bug reports and patches. Most commits were done for Ubuntu Calculator and Ubuntu Clock by fixing bugs which were approved by Riccardo Padovani, Mihir Soni and Nekhelesh Ramananthan. After some time, I became member of Ubuntu Core Apps. It’s very fun to work with these guys and the Ubuntu community. I’ve learned a lot about Qt/QML and user experience design.

3) How do you approach implementing a design in your apps?

Generally I follow the design document during implementation and sometimes find parts that need to be improved. After speaking with the Ubuntu UX team, we discuss various issues and agree on a final design solution. Sometimes the UX team gives us freehand, so we could design some parts by ourselves (eg. Stopwatch, Welcome Wizard, Landscape View). It’s really fun to work with such awesome guys.

4) What feature would you like to see in the future?

I think from user perspective, longer battery life is a very important topic. The power usage is higher with white background: https://www.quora.com/Does-a-white-background-use-more-energy-on-a-LCD-than-if-it-was-set-to-black especially with OLED screen. I wish that Ubuntu Touch came with a darker theme, to save battery on OLED screens.
