KDE Accomplishments - Google Summer of Code 2013
Google Summer of Code 2013 (GSoC) brought fifty budding new shoots and branches to the mighty KDE family tree, and the canopy of warmth and love offered by the community helped them blossom and bloom in the three months of the program. With a few snips, a little trimming and pruning, they have learned, innovated, created and contributed to one of the largest free and open source communities in the world, and have developed software that will touch many people around the world. They now have their roots firmly planted in the KDE community with the successful completion of their projects and are ready to shelter budding shoots to come!
GSoC students and mentors shared thoughts about their awesome experiences:
- Matěj Laitl (who is working on Amarok) joked that what he loved most about GSoC was that he got to spend his summer flipping bits instead of burgers!
- Akshay Ratan (Plasma Media Center) shared, "The satisfaction of working on a real life project and writing code for software which would perhaps be used by millions of people is indescribable. The entire journey was truly remarkable and cannot be forgotten."
- Lukas Appelhans (Muon) said, "It's refreshing to see that one is able to create a fixed project in a set timeframe, something which I always felt being hard to achieve!"
- Albert Vaca (KDE Connect) felt that he learned a lot throughout GSoC and was happy to work with such awesome mentors and believed that without their help and advice the project wouldn't have been possible.
- Yiou Wang (DigiKam) said, "I first saw the GSoC poster in 2012 but at that time I didn't believe myself to be qualified enough to participate in it. But this year, my final year in college, I had made up my mind and this entire journey was a great learning experience for me!"
- Andrei Duma (Marble) said, "It has been an amazing summer during which I've learnt so much. I have evolved from a web newbie to a web enthusiast and had the chance to meet great people."
- Claudio Desideri working on Gluon as a part of GSoC said, "I should be glue to the great work done in all these years by the Gluon team in various parts of the project." This along with "the possibility to learn new things, work on so many parts of a project, with so many technologies" kept him motivated!
- Utku Aydın discovered something interesting during GSoC, "...that one can have a love–hate relationship with C++."
- Lydia Pintscher, KDE's main driving force behind GSoC, said, "I'm thrilled to see our community take such a large number of young bright people by the hand. Google Summer of Code and KDE have made such a profound difference in the lives of the students of previous years. I am looking forward to seeing where this year's students are going and how the projects they worked on are going to turn out."
Proud Accomplishments
Artikulate Oindrila Gupta worked on Artikulate, the KDE pronunciation trainer. Artikulate is still under development, but she, along with an OPW (Outreach Program for Women) student, has already accumulated recordings and translations including support for Polish and French languages, and is also implementing GHNS (Get Hot New Stuff) in the program. Artikulate is intended to revolutionize the learning process for new languages. These two students plan to introduce this addition to the KDE umbrella of projects that will be released as a part of KDE Edu.
