2010-04-28T13:03:23.603-03:00Last Monday, Google announced the list of accepted projects for the Summer of Code Program. Like last year, Maemo has got 10 slots. As Valério said in a previous post, we received about 90 submissions this year, which made the task of selecting the best proposals much more difficult. Many thanks to all people involved on the selection process. :)Enough talk. Here is the list (in no particular order, just copied and pasted the contents of the wiki page):Porting Canola to Maemo 5 and beyondStudent: Andrei Mirestean (andrei1089)Mentor: Eduardo Lima (etrunko)FaceBrick - a facebook client for Maemo / the N900Student: Kamilla Bremeraunet (brik)Mentor: Robin Burchell (w00t)UPnP Remote AccessStudent: Sunil Kumar GhaiMentor: Zeeshan AliThe Tablet of Adventure: a location-based social adventureStudent: Susanna HuhtanenMentor: Henri Bergius (bergie)Extending ShepherdStudent: Linus Wallgren (ecksun)Mentor: Attila Csipa (achipa)eBook reader for Maemo 5Student: Juhana JauhiainenMentor: Valerio Valerio (VDVsx)Gtk+ Input Method for the Harmattan Input Method UI FrameworkStudent: Javier De San Pedro MartinMentor: Mohammad Dhani AnwariTransifex mobileStudent: Lauri Vosandi (v6sa)Mentor: Thomas Perl (Thp)Optical Page Reader for the N900Student: David JordanMentor: Florian Boor (Florian)MeeGo Cloud Storage IntegrationStudent: Eli FoleyMentor: Yan LiCongratulations to all accepted students! Some of them already had worked on projects related to Maemo on GSoC last year. In either case would be really cool to post a small introduction about yourself and the project you will work on during the next months. If you have a blog, request it to be syndicated on Planet Maemo.For those whose projects were not accepted, and still think it is worth to work on it, you are be more than welcome. Although there won't be any assigned mentor, I am sure you can find help on the mailing lists.[...]
2009-09-02T10:52:46.989-03:00Hey there. I've been extremely busy working on a very important project which is driving me and almost half of our crew mad. :P
2009-06-19T00:36:02.673-03:00Warning! Long long post ahead!Well, I was supposed to post news here more often, but it's been quite impossible to do it due to the day to day work. Bullet point to the rescue!!!Google Summer of CodeThanks to Valério who arranged everything, Maemo has got 10 slots in this year edition of Google Summer of Code. We received very good proposals for projects, but I never expected as much interest in Canola as we got in the end: 5 out of 10 projects are related to Canola. We'll surely have great results by the end of the program in August.Mozilla/Maemo Danish WeekendThe hackfest was really great. The idea of gathering together the main Firefox add-ons developers to get them ported to Fennec and the developers of Fremantle Stars at first seemed a bit weird in my point of view, but in the end it proved its worth. My travel was ok, but I felt really confused because of the jetlag. I only managed to get used to the timezone in Lisbon, during my trip back to Brazil.The IT University is a wonderful place, and the architecture of the building is just stunning.The opening party on Friday was a great opportunity to meet the already known and new faces. I could take part on some good discussions about Free Software, mobile devices, traveling, and many other things I can't remeber by now.In the way back to the hotel we realized how fun can it be to get a train in Copenhagen after having drunk some beers.It felt like we were traveling through time. Niels could express it better :D.Saturday morning after a quick kick-off by Quim and William, we had a track with presentations related to Mozilla. Time for the Maemo guys, myself included, to start working on their projects. I managed to get together with 3 of the 5 students that are participating in this year edition of Google Summer of Code: Andrey Popelo (Remember the Milk plugin), Andrei Mirestean (Picasa plugin), Lauri Võsandi (Bittorrent plugin).In the afternoon it was time of the Maemo track. We had very interesting talks: The first one about the new version of the platform and device. Quim showed us a development prototype unit and it seems really promising. Can't wait to see the final product. After that, quick presentations about the Fremantle Stars and a presentation about Canola, where I made the announcement about the exception in the GPLv3 that we adopted targeting new opportunities of adoption of our software.During my presentation I also demoed the new version of Canola, yet to be released, and the students working on the GSoC projects introduced themselves and their projects to the attendees. In the end of the talk, I presented some rough plans of the points we expect to work on for the near future.After my talk, we had the last two presentations about the awesome Mer project. :)On Sunday we were able to hack almost all day long. It was quite productive and I could help the students a bit and fix some nasty bugs in Canola and plugins. I also kicked off the work of porting the EFL packages to Fremantle, thanks to Jeremiah's valuable tips. It was a great event, thanks to everyone who worked to make it happen and also to Nokia/Mozilla for sponsoring my travel and accommodation. I really hope to be able to attend the Maemo Summit later this year in Amsterdam. :)FISLThat's what has keeping me busy lately. There are about 15 people from INdT going to Porto Alegre to attend the tenth edition of the Fórum Internacional de Software Livre (FISL). I'll give a talk about Canola and how it can be extended to bring new experiences to the users. Some guys from Qt Software are coming to FISL as well, and we're helping them to arrange everything with their booth.We are also organizing a challenge where the winner will receive a N810 Internet Tablet, Nokia Bluetooth Speakers and one week stay in Recife for a training on the latest Qt technologies which we're helping to develop.CanolaAfter the Mozilla/Maemo hackfest I started to work on the new release of Canola and consequently, EFL. At the moment we already h[...]
2009-04-03T00:35:00.784-03:00This is just to remember the students interested in participating in this year edition of Google Summer of Code that the deadline for submitting new proposals is today (Friday, April 3rd) at 19:00 UTC. If you want to develop a project related to the best software platform for mobile devices out there ;), becoming part of this exciting community and after all earn some money with it, this is your last chance. (At least until next edition of GSoc).
2009-04-01T18:14:45.114-03:00As seen on Engadget Mobile:
2009-02-13T00:50:33.434-02:00(image) If you've been following the updates in extras-devel repository you might have already noticed that we've been working on the new releases of the Maemo EFL stack together with Canola and Carman. Important to say, now that we have more applications (FTW!) depending on the core Enlightenment libraries we need to ensure that the upgrade won't break anything.
2009-01-27T02:17:27.350-02:00As part of my job at INdT, I was responsible for providing a unified solution for hosting the source code for our open source projects, such as QEdje, Carman and the yet to become free, Canola, amongst others.There was only one major requirement: Git as our VCS. Of course we could simply provide a server with access for writing restricted for a few selected users and running gitweb for anyone interested in following the development of the projects.We had already tried this approach with our projects internally, but it had proven to become visually a mess as the number of projects and users grow along time. Also, the amount of time spent with the server administration was really bothering many of us.Enter GitoriousBack in September, when some of our colleagues came back from a trip to Oslo, Norway, where they worked for a couple in collaboration with Qt Software guys, they brought with them lots of fresh and great ideas on how to improve our own processes.One of these ideas was to make use of Gitorious as a tool for managing our git repositories. I had already used gitorious before, during the 2008 edition of Google Summer of Code, when I co-mentored a student in the implementation of bluez-python. One thing I didn't know though is that Gitorious itself is a Free Software project and its source code is available in the very own website.Artur and Caio worked hard to setup an instance of Gitorious running on our internal server. We started using it for a few selected projects experimentally, and in a couple of months all of them had been moved to the brand new host. In time, this is just one the countless advantages of Git (and maybe others DVCS) over a centralized VCS. It was just a matter of adding a new remote and pushing the repository to it.With Gitorious I was able to have contact with a completely new world in the Computer Science universe (at least for me): Web development. It is written in Ruby over the Rails Framework. At a first glance, everything looked awfully weird, from the language syntax to the Rails ways of doing things. It took me considerable time to get used to them, but I could successfully adapt the code to our needs.You can see the final result in http://code.openbossa.org. As it can be easily noticed, we have created just a few projects there, but the idea, as already stated, is to move all of our Free and Open Source Software projects to this new server as soon as possible. Notice that the site is not meant for openBossa/INdT employees exclusively. If you want to contribute to one of the existing projects over there, it is just a matter of getting in contact with the owner of the project and try to convince him you deserve an account. Even better, if you have a developed something related to one of our own projects, such as a Canola plugin, we are more than happy to host it. :)[...]
2008-05-20T23:03:52.439-03:00With Canola2 beta9 finally out, people have asked about the ogg support for Canola. Well, let me first try to clarify things a bit: ogg support actually has not much to do with Canola itself, but more with lightmediascanner.In our architecture, the component responsible for scanning the media, amongst other things, is canola deamon (canolad for short). Canola daemon is Free software, released under the GPL license since its very first version. You can get the source with a simple apt-get source command.When the user marks a folder as "scannable" on the "Media Folder" section in canola settings, it will call canola daemon to add that folder to the list of folders it will have to scan. Canolad then invokes ligthmediascanner (lms for short) which will scan for media on those folders.LMS makes use of a very clever plugin architecture implementation, where each plugin is responsible for gathering metadata from that specific type of file it was developed for. So far there are implementations for asf, flac, id3, jpeg, m3u, mp4, ogg, pls, png and rm files. Dummy implementations for audio and video files will index files of given file extensions.The ogg plugin was making use of libvorbis, which provides the reference implementation for the standard, but it was not being installed by Tuomas' packages. At this moment I sent him an email asking if it would be possible to have the package installed on the device. He then said it was perfectly feasible, but not advisable, as the implementation makes heavily use of floating point operations. Everybody knows how floating point operations perform on our target platform. And it doesn't really fit our purposes. Tuomas suggested that LMS ogg plugin should make use of libvorbisidec, also known as Tremor, which was specially implemented taking into account those performance problems of floating point operations on embedded devices. It provides a fixed-point implementation for the Vorbis decoder.At first glance, I thought it would be a really trivial task. With a few modifications in the configure.ac file, the ogg plugin would link against libvorbisidec and everything should just work! And of course I was so very wrong... I first spotted some severe bugs in the lms ogg plugin which were causing segfaults. Having those fixed was the easiest part.The most difficult thing was to find out after some time digging that libvorbis and libvorbisidec implementations are not compatible at all. Only after that I could be able to end up with the final solution for the problem. You can now build lightmediascanner with ogg support using either the regular vorbis or tremor implementations.With LMS now being able to scan and index ogg files, I came back to Tuomas and provided the patch that creates ogg-support-lightmediascanner meta package, which will install both ogg-support and lms ogg plugin as dependencies.No change in the canola side was needed, since the whole work of decoding and playing ogg files was already being done by ogg-support packages provided by Tuomas. Big kudos to Tuomas and his hard work and as well to Gustavo for reviewing and pushing my patches for LMS to mainstream.Install it now and enjoy![...]
2008-04-24T15:58:57.407-03:00Yesterday I uploaded a new version of the Canola2 Youtube plugin to maemo extras repository. Youtube has changed the way it references the .flv file, breaking the way we were dealing with it. Kudos to Adriano who's been doing an excelent job maintaining the plugin.
2008-04-09T10:37:51.408-03:00Really exciting news!! This wiki page on eLinux.org describes with details the instructions for running Google's Android on OMAP based platforms, such as the Nokia Internet Tablets. There are also threads on Android Internals and Linux OMAP mailing lists.
2008-03-25T14:22:31.648-03:00It's been quite a long time with not even a update in my blog. Shame on me!!! Since last December, lots of things happened and if I tried to tell everything, you would be surely bored to death. So here goes some highlights of the last 3 1/2 months:Canola2We're now on the version 7 of the beta series and we're working really hard to release the final version, which should come really soon. Besides the name "beta" it is pretty much stable and in each new version released it becomes better and better. Many thanks to the users who provided useful feedback (specially on ITT forums) and to Marcelo, who is being patient enough to provide the answers to almost all users questions.I have been maintaining the packages for both Canola2 and the Maemo port of the Enlightenment Foundation Libraries for each and every one of the Nokia Internet Tabled devices and ITOS releases, not including ITOS2005 here. It has been a very time consuming task and I have not been able to code much since then.We've opened the gates for 3rd part plugins releasing the youtube plugin for Canola2. It's only in its very first version and users seems to like it a lot. The source code is availabe under the GPLv3 and can be used as base for development on new plugins. The next one in the line is the last.fm plugin.New themes were released and the source code for them are going to be released as well.ToysFound a 1GB iPod shuffle *inside* an ice cream. Literally.Sold my old car, a Fiat Palio (1998 year) and bough a Peugeot 307 (2002 year), previously owned by Renato Filho. All I can say is it was a great acquisition. I'm very happy with it. By the way, Renato bought a newer Fiat Palio (2004 year) but I'm not pretty sure if Renato can tell the same though. :)Got a Nokia N95 phone and gave my N73 to my girlfirend. Another huge improvement here. How could I live until now with a phone without WiFi and GPS integrated?Bought my Nokia N810 with the discount code I got back in November. Many thanks to Hallyson and Tapani who brought me the device from Finland straight to Brazil.Bossa Conference '08It was a really great conference this year. If last year was good, this one was even better! We had some high level talks and lots of free time to meet and talk to the guys about problems of using new technologies in mobile devices and possible solutions for them. I really enjoyed Clutter, Webkit and PulseAudio talks among others. Congratulations to the organization crew who worked hard to make it happen. I took some pictures with my N95 and uploaded them to my flickr account. The photos are basically from the after hours parties and can be seen on this set.Google Summer of Code 2008I'm willing to help the BlueZ and Enlightenment guys by mentoring projects in this edition of GSoC. More details on this subject later.[...]
2007-12-10T15:09:31.099-02:00We're running against the clock to get the Canola 2 release ready by the 12th. It has been a week since I'm working on providing the proper debian packages for all the dependencies, so the installation process can be as smooth as possible. After having coded a
2007-11-29T17:11:47.862-02:00A while ago we were curious about how would be the performance of the new version of Canola running on a Nokia 770 device. After a whole day building packages and compiling stuff, our mate Renato Chencarek was finally able to make it run on the device. We thought it also deserved a video, just like others we posted.
2007-11-15T01:34:02.455-02:00It seems lots of people got interested in Reinteract. Owen Taylor has started a new project page and integrated the patches people sent him. Guess what? The maemo patch was integrated to the branch master as well. It was slightly different from the first patch I provided in my previous post since I had forgotten to add support for hildon file chooser dialogs. We also agreed provide a way for the user to select which UI to run, the standard or the hildon one.
2007-11-11T15:59:25.257-02:00I followed a couple of posts today in Planet Gnome and read about Reinteract. This project is freaking awesome!!! Watch the screencast. It worths every minute. Reinteract is something that fits like a glove in Maemo. I've started playing with it a bit and a few minutes later I got something really interesting:
2007-11-11T13:12:05.469-02:00It seems the OS wars has been reaching new levels. After Windows Vista soft drink, we have also Ubuntu Cola.
2007-11-09T16:24:09.647-02:00I've just read in the Maemo site news The final Chinook SDK has been released, what means the N810 device is shopping in the next weeks. I haven't noticed it in the moment I received the email about the N810 discount program. Great news!!! I have already downloaded and installed the rootstraps which can be found here.
