Last week from 29-Sep to 01-Oct we had the amazing 7th PythonBrasil conference, for the first time in São Paulo.

Since I’ve start to use Python in 2002 I loved the language, but after getting introduced to the PythonBrasil community in 2004 I’ve boosted my development skills, got some friends and even my first job (INdT-Recife) was a kind recommendation from Osvaldo Santana in 2005.

By 2005 we had the 1st PythonBrasil Conference, then called PyConBrasil, here in Campinas with the help of UNICAMP and our amazing non-stop contributor Rodrigo Senra. It was very cool, I even presented a talk there… and it motivated me to go to following conferences in 2006 and 2007 as well.

However if starting to work at INdT reduced my spare time since late 2006, after ProFUSION was born in 2008 I had no time to participate in the lists or even go to conferences. What a shame!

I couldn’t see how shameful it was until I did this PythonBrasil in 2011. I’ m yet to see a conference with so kind people. People still remembered me and I was ashamed when I couldn’t remind their names… although they did remember mine (NOTE TO CONFERENCE: bigger names next year!) Some would even let me know they still use Eagle-Py, something that I already forgot about. And people I had closer contact before were willing to talk as if we had met last week. Amazing.

During these talks I’ve catch up with Rodrigo Senra, Luciano, Osvaldo, Erico, Marco André, Sidnei, Fernando and many more I couldn’t remember. However one of the talks was very special: talked to Gustavo Niemeyer about Go programming language. That’s right, people were so kind and open we had a keynote about Go, and we talked a lot afterwards without problems!  Gustavo showed me some nice details about the language and my mind is now burning! I must do Enlightenment Foundation Libraries (EFL) + Go = EGO, a perfect GUI tool.

But I was of use… not just a leecher! I went there to present 3 talks (slides in Portuguese!):

• Tudo que você sempre quis saber sobre Bindings
• Python em sistemas embarcados: Sim ou Não?
• Canvas-2D extremamente rápido usando EFL

Last but not least, I’d like to thank everyone that did this amazing conference possible!

Lots of systems do not support multi-window on their own, consider standard Linux Frame Buffer (FB) or the PlayStation3. This makes it cumbersome as you’re restricted to a single window,  likely you’ll have to rewrite your apps to behave well in this scenario.

While most projects praises portability with fancy things like “gchar” (Gtk), fancy names like “LightHouse” (Qt) or completely new abstraction concepts, The Enlightenment Project always choose a simple approach to use POSIX and fill the gaps as required. This requires much less work and yields the same or better results, as we could see in the past and now being the first toolkit to be ported to PlayStation3 (native, no Linux)!

As announced by the the developer, KaKaRoTo, in our official news the port was done on top of our existing SDL backend in a couple of days, then being migrated to native PlayStation3 using unofficial SDK PSL1GHT for jailbroken systems. There is still no hardware acceleration, yet it runs fine a physics game at Full HD.

Right now we have port to MacOS and Windows, including WinCE. Given our scarce resources we do not lag behind Qt or Gtk in portability front. Basically what we have is one brave developer called Vincent Torri that is a Math professor and do it on his spare time!

Vincent could do it by keeping our approach: use POSIX and fill the gaps. He created “Evil”, a library to provide missing functions to Windows. Kakaroto then created “Escape” to do the same for PSL1GHT. Seems this approach works fine

I had the pleasure to attend the DesktopSummit 2011, a great event that happened in Berlin from 5-12 of August 2011. As I’ve mentioned in an earlier blogpost my focus was to highlight Enlightenment’s opinion that performance matters and that we need broader standards in freedesktop.org. Of course I explained a bit about our history and the current status of E17. The presentation file can be downloaded here.

I’m proud to announce LightMediaScanner 0.4.4 was released and I’d like to take some time to remind you of this awesome project

Hi all,

After a while not even opening my blog, yesterday I did two posts. While the administrator interface seemed fine, readers quickly notified that it was showing lots of spam in the regular view which I confirmed using Chromium’s private browsing. Investigations led to dozen administrator accounts in WordPress database, then I decided to reinstall from scratch. Unfortunately yesterday was a busy day and I could barely stay at the computer to do so.

Anyway, this morning I restored my blog and I’ll try to keep it updated I also changed the comments rule, instead of requiring people to register, I instead opted to close comments after 14 days, since most spammers seems to look for pages with reasonable pagerank and new pages do not have them that soon.

The first Embedded Systems Conference Brazil was held at São Paulo on 24 to May 25 2011 and ProFUSION was there to do a technical talk.

Hi all,

Hello people, as most of open source lovers I’m still trying to digest Nokia’s move to WP7. But although many are worried about the future of Meego or the Linux on mobiles, I’m quite confident.

First, as said before MeeGo is not just about Nokia or phones, it’s also being pushed as In-Vehicle Infotainment (IVI) and is already adopted by BMW, which you can see daily contributions on projects such as ConnMan. So let’s not assume it is the end of the world given Nokia’s action.

Second, although Android and WebOS are indeed Linux since they use this kernel, we often want more traditional user-space stack, like MeeGo would be. For those,  don’t loose hope! Today (Feb14, 2011) we got a major announcement at MWC by LiMo: LiMo Foundation Unveils LiMo 4. It’s based on X11, WebKit, GNOME and… EFL!

Wait? Where do you see EFL in that announcement? You’ll have to check What is the LiMo 4 Platform? block diagram and see EFL is now a first class component at it, together with GNOME that was there since first release. Yeah, we surely could use better publicity at EFL side

The release is still just text and no code, which should be available by July2011, however you can get code straight from EFL SVN.

ProFUSION team is happy due our contributions to make this possible, after all we help with EFL and WebKit-EFL developments!
