Food and exercise

Note to the organizers: thank you for providing lunch, this helps us keep focused on the event and not having to roam around to get something to it. And a special thanks to the cookers: we are getting home-cooked Jamaican stuff, which is great and very similar to Brazilian (rice and beans, and a lot of fruit.)

Till’s second part of training is starting right now, and he will cover QConcurrent. At the end of the room, Jos seems to be practicing some sort of writer’s yoga, from what I can tell:

@ Jamaica

Camp KDE is going well, and Jamaica is amazing. Lots of action yesterday, and today I am going to share a presentation slot with Marcus to talk about KDE Edu and KDE Games. Everything is prepared, hope it goes out well. Videos will be available later at the web, according to the organizers.
I did not have time yet to go to the beach, but today I woke up before the sunrise, and took some photos there, including a failed attempt to do a Camp KDE logo at the sand ­čÖé

Anyway, it will be interesting to share ideas about KDE Edu and Games with people that know much more than I do about the project! I am hoping to get a lot of feedback that we can use in 4.3 and for the future, and maybe do a BoF tomorrow to learn a bit more.

2008 in review

While reviewing my involvement with KDE in 2008 I realized that 2009 is starting in a similar way: I spent the last week or so making sure we had kdegames translated 100% to pt_BR, much like in the first days of 2008. Of course, not all things are equal. We now have several new games, and the pt_BR translation team is stronger than ever, with huge efforts driven by Boaglio mostly, and epic commit logs by Luiz Fernando Ranghetti. So we are still maintaining 100% for releases, even with several new games available, among them Kapman, bomber, Kblocks and some big ones, like KsirK!
Speaking of KBlocks, this is the first application I wrote from scratch for KDE. It is a nice exercise in using the newer kdegames API and QGV as well, and it is shaping up nicely. It still does not replace everything ksirtet had, but it is more customizable, and hopefully ready for additional expansion. It made its debut in 4.1.
At the beginning of the year I was also contacted by the guys at LTIA, at the state university (UNESP) headquartered at Bauru. They did a wonderful job in KBruch, remodeling the application almost entirely, after attending Akademy. Results are now part of the kdeedu package in KDE 4.2, and I hope this will mark only the beginning of this collaboration.
In Akademy it was great to finally meet Niels Slot, which is keeping the KTurtle app afloat while I am very busy and Cies is doing his world tour. Still we all managed to collaborate a bit and incrementally improve the application: I think the version shipped in 4.2 is better than the one in 4.1, which was better than the one in 4.0, and so on. I think this is the beauty of having a team that can take turns developing the same code, and sharing ideas.
Speaking of Akademy, in 2008 I traveled a lot representing KDE, kdegames and kdeedu. In February I had a presentation at Campus Party Brazil, which ended up putting me in contact with Fausto from the Brazilian Ministry of Education. This contact was reinforced during the first Brazilian KDE Meeting at FISL, which generated several initiatives. I also got interested in the ProInfo effort by MEC, and ended up visiting their team in Brasilia in May. Recently I have not heard much from them directly in the last couple of months, but apparently they have a new release and the project is on track. I will keep you guys posted.
Continuing the trip summary, I went to Akademy to talk about ProInfo, and then also did a talk at Bauru concerning KDE graphics and designers. To close the year we had our first Latin American KDE Forum, at LatinoWare. KDE had a huge presence there, with Helio Castro, Boaglio, Frederico, Tomaz, Sandro, Cristiano, Roberto and Alvaro. We are looking forward for the second edition! Huge thanks to the organizers for sponsoring the travel and accommodations for all involved.
Speaking of sponsorship, I also want to thank the KDE e.V., which sponsored partially my Akademy air ticket. For the oher trips I took during 2008 I was able to fund my expenses, but without their help I would not be able to be there. They will also help me go to Camp KDE, where I will co-host a talk slot with Marcus Hanwell. We will try to step in Eugene’s shoes and cover KDE Games and Edu, mixing Avogadro, graphics, community and development in a 1 hour slot. Let us see
Development-wise I did not do so much this year, other than KBlocks. I helped polishing a lot of games and kturtle for 4.1 and now in the final 4.2 sprint, and even managed to do some simple artwork for kapman at the end. I hope I will have more time in 2009 to continue working on the project. The 4.2 release is really inspiring, I am using it as my main desktop for a while now and all of the rough edges have been trimmed significantly.
So, to finish this long post, I hope to see some of you guys and girls tomorrow in Negril. After all…

First Latin American KDE Forum

KDE will have a strong presence next week, at LatinoWare 2008, Foz do Iguaçu, Brazil. We will have 7 presentation slots, as part the First Latin American KDE Forum.

Festival Software Livre

UPDATE: The Festival was cancelled, unfortunately. LatinoWare is coming up in October 30th, though.

[en]
I will be in Brasilia for a free software event, the "Festival de Software Livre". We are planning to have a games arena with KDE Games in all computers, and I will talk about the techniques we use to create games in KDE, and how to participate in the project. It will also be a good chance to meet other KDE contributors in Brazil, including Fernando Boaglio, who is one of the leaders of the pt_BR localization team and will also host a talk at the festival.

KDE and LatinoWare 2008

Last year I blogged about LatinoWare and the possibility of organizing a KDE Latino meeting in 2008, with the help of the organizers. You can find more about this at:

http://piacentini.livejournal.com/4777.html

LatinoWare’s website for this year’s conference is still in constructions, at

http://www.latinoware.org

It will be a big event, from Oct 30th to November 1st, 5000 people are expected. The geographical location is perfect for the intended audience, in the middle of the triple frontier between Brazil, Argentina and Paraguay.

We (Helio Castro and me) are going ahead with the plan for a KDE event there to promote the KDE community in Latin America. There is a possibility that we can get a 250 person auditory for a full day of KDE talks, and also a computer lab for one full day as well for tutorials and workshops. Some help for transportation and accommodation can probably also be arranged for speakers that live in the Latin American region.

The idea we discussed last year was to also have a Gnome Latino event going on in parallel, same infrastructure, and at the end of the day we could do one shared panel. I still do not know if the Gnomes are going ahead with their side of the plan, but if it happens it can be a small preview of next year’s co-hosted Akademy/GUADEC event, and will help forge stronger ties between our communities.

So, this is a call for action. We need volunteers for the talks and tutorials, and there is not much time left if we want to make it happen. Please send me a proposal for a talk or workshop if you are interested in coming until August 27th, to piacentini (at) kde.org

Building software together

I want to talk a little bit about the ongoing collaboration between KDE and Ltia, the  Applied Information Technology Lab – Laborat├│rio de Tecnologia da Informa├ž├úo Aplicada  (http://www.ltia.fc.unesp.br). Ltia is connected to UNESP – a state university in Sao Paulo, Brazil. Currently there are about 30 people working at several projects in the lab, in different areas like User Experience, Embedded Development, Software Development and Information Technology.
Ltia has just started a 6-month project with several stages involving five people: Paulo Cattai and Roberto Cunha will work with usability, user experience and pedagogical evaluation of applications, while Danilo Balzaque, Tadeu Ara├║jo and Tiago Porangaba will do the actual coding implementation. For this project they have selected four applications: Kbruch, Kpercentage, Kalzium and Ksudoku. They will work on usability enhancements and some new features related to the usage of these programs in the educational environment, of course always in close cooperation with the existing maintainers and the KDE Edu and KDE Games community. Work has already started on Kbruch, and we can expect the initial results in a few weeks. Of course, the goals of this project are to improve the educational applications and foster collaboration between our community and other institutions, so we can learn from each other. Ltia uses a more formal development structure for their internal projects, and it should be interesting to see how well this can work in association with KDE’s more informal development processes.
Things seem to have started well: Paulo and Tiago are here in Belgium for Akademy. Celeste Paul and Ellen Reitmayr have already exchanged usability advice and some guidelines with them, and the guys seem right at home in the hacking labs and sessions. According to Paulo, “this is an opportunity to push ourselves and learn more about user experience in a large scale project, and share this experience with the lab team and with the academic community.”
I hope collaborations like this one can become more common in the future, and I would like to help it happen. In other words, this is a call for other universities in Brazil with computer science and design labs to contact me and see how we (you and KDE) can work together on building better open source educational software and games in the future.

BTW, I am taking a Nokia 810 tablet with me back to Sao Paulo. These nice little gadgets were distributed at Akademy to encourage development for smaller form factors, and I think they can help us learn how to test and adapt our interfaces to this new class of devices. This is something that will be useful for delivery to netbooks and other small screen laptops (OLPC, Classmate) as well. As I know it is very difficult to get one in Brazil, I am going to make this one available for people who want to play with it, so if you are involved in an educational or game project and need to lend it for some time, please let me know, ok?
