It has been a while since my last post here but I’m willing to put this blog back to life and write some stuff here.

To restart it I’d like to tell that I’ve attended Akademy 2010 conference in Tampere-Finland from july 2th to july 4th and it was simply great.
It is always good to met people that you don’t know and put faces on the irc nicknames. Talking about people, Here are the group photo.
It was also good to meet other Collaborans and old friends there, which presented good stuff:
* George talked about telephaty
* Fleury came up with great new ideas for Qt and KDE styles
* Artur presented the Plasma mobile

There were other great presentations there as well.

So, what is next here in this blog?

Well, I know that we are far away from the new year’s day when people do lots of promises for next year but it is time to promise some posts here in this blog.
Some of these promises are in my todo list for a while and I hope that after promising it will force myself to write them soon.

You can wait to read here on next days/weeks about:

* linuxcon Brasil that is comming soon (Aug 31/Sep 01, where I’ve just confirmed my participation with a presentation.
* tip for N900 users to save the battery.
* Garmin Navigator impression.
* MeeGo
* Syplifying memory measurement

Not exactly on this order, but to be honest I’ve already started to write most of them while I’m in an Iberia flight to London through Madri.

“MeeGo is an open source, Linux project which brings together the Moblin project, headed up by Intel, and Maemo, by Nokia, into a single open source activity.”

Ari Jaaksi has written a very informative announcement. Read it.

Some Highlights:

  • “The development and integration will be open, too. Everybody can invest in MeeGo and participate. It is a genuine open source project.” (Ari Jaaksi)

So, I hope to see the build system open also…

This is a quick post to announce that I left INdT and joined Collabora.

These 3 last years at INdT was simply fantastic. Thank you (INdT) guys for everything. I wish the best for all of you guys.

Now it is time to move on. I joined Collabora today. Thank you (Collabora) guys for the good reception. Let’s rock.

I intend to write more technical posts related to the work at Collabora. (latter/in the future)

GVT is definitely coming to Recife: I took this photo here in my street (Mamanguape – here in Recife) this morning when they were installing this optical cable.

For those that don’t know: Here in Recife, the fastest internet is provided by Oi (1 Mb)… No, I’m not kidding: 1 (one) Mb only.

This week we were talking about GVT and someone asked: “how much does GVT 1Mb plan cost?” Everybody else start laughing because GVT has plans from 3Mb to 100Mb.

We,ll have fast internet in Recife, finally.

I’m from Platform team and I’m not working directly with Qt here at INdT, but it is amazing to see other people here engaged with Qt and doing an amazing work:

Recently, Qt Labs Americas was created. It is an openBossa initiative aiming the growth of local Qt and KDE communities all over America, starting in Brazil.

It was cool to see our Python team working hard on PySide which is a project that provides LGPL-licensed Python bindings for the Qt cross-platform application and UI framework.

Congratulations guys.

* English Version below *

Versão em Português:

Este será meu primeiro “post” escrito em Português e em Inglês ao mesmo tempo, a fim de atingir o maior número de leitores para esta minha crítica. Os usuários desse “Fenix Systems” provavelmente se sentirão mais confortáveis lendo em Português e talvez alguns donos de empresas ou investidores prefiram em Inglês.

Minha namorada estava procurando um notebook para comprar e eu como um computeiro devia ajuda-la. Nesta procura eu fiquei feliz de ver que havia muitas marcas vendendo notebooks com Linux. Não que isso fosse uma novidade para mim, mas é legal ver de perto uma quantidade imensa de notebooks com Linux nas prateleiras. Fiquei ainda mais feliz ao ver que ela estava disposta a comprar e usar o notebook com Linux. No final, ela comprou um Notebook Intelbras com Linux.

Ao liga-lo vi que o sistema era um tal de “Fenix Systems” e achei q fosse mais uma distribuição Linux. Antes fosse. “Fenix Systems” é uma gambiarra completa. Eles pegam uma distro qualquer e enchem de tranqueiras deles que não funcionam direito e inserem muitos erros e problemas. Neste caso, era baseado em um Ubuntu, mas ouvi dizer que antes disso eles se baseavam no Kurumin.

Eu irei enumerar os erros encontrados:

1 – Tudo é muito feio, desde o primeira imagem de “splash screen” até o fundo de tela.

2 – Durante o boot várias mensagens de erros exibidas.

3 – Video mal configurado. Não usava a resolução indicada e fazia com que as letras ficassem embaçadas.

4 – Ambiente muito poluído com uma mistura dos ícones de desktop do MS Windows com uma mesa do MacOS X

5 – E o mais tosco de tudo: Um HD de 120Gb com apenas 12Gb acessíveis, decorrente de um particionamento mal feito.

Pelo amor de Deus, quem é que me vende um produto sem estar configurado a 100% da sua capacidade?  Uma empresa que não liga para seu consumidor ou uma empresa que acredita que 100% dos usuários só irão comprar o notebook com Linux pelo preço e depois instalar um MS Windows pirata nele?

Além disso as empresas contratadas para colocar o Linux deviam se preocupar mais em entregar o produto a 100% do que a colocar seus gráficos feios. E isso seria bem simples: Instalar o Ubuntu/Kubuntu como eles são.

Após passar algum tempo brigando com o  “Fenix Systems” eu desisti e instalei o Kubuntu com a instalação padrão e magicamente tudo estava funcionando a 100%. Mais simples, não?!

English version:

This is the first time that I use Portuguese and English at the same time in order to get lots of readers. Probably the Fenix Systems users will fell comfortable reading it in Portuguese and maybe some company owners or investors prefer English.

My girlfriend was looking for a notebook to buy and I as a computer guy should help her. I got happy when I saw lots of brands selling their notebooks with Linux on it. Ok, there is nothing new on it (at least here in Brazil), but it is cool to see by yourself a huge quantity of notebooks running Linux on the shelves anyway. I got happier when I noticed that she was willing to buy and use a notebook running Linux. In the end she bought one.

When I turned it on I noticed that Fenix Systems was running on it. I thought it was yet another Linux distribution. I’d prefer that. Fenix Systems is a complete workaround. They get any Linux distributions and put their trash that doesn’t work properly and add lots of errors and problems to this system. In this case it was based on Ubuntu. I heard they used Kurumin in the past.

I’m going to enumerate the problems I faced:

1 – Everything is very ugly, since the first splash screen image up to the background image.
2 – Lots of error messages during boot.

3 – Video was not properly configured. It wasn’t using the best resolutions and the letters was blurry.

4 – Polluted environment using a mix of MS Windows desktop icons with MacOS X table

5 – And the worst thing ever: A 120Gb HD with only 12Gb accessible due to a bad partitioning.

For the God’s sake who the hell sells a product without being at 100% of its capacity? A company that doesn’t care for its clients or a company that believes that 100% of them will buy the notebook running Linux by the price and will illegally replace Linux by MS Windows?

Besides the companies hired to put Linux on it should worry about delivery a 100% functional product instead of put their ugly images. It would be simple: Install Ubuntu/Kubuntu as they are.

After spend some time fighting against  Fenix Systems I gave up and installed Kubuntu using its default installation and magically everything was working at 100%. Simple, isn’t it?

Marcelo has recently posted a Canola portrait test video on his blog.

The most impressive thing it that almost of Canola fits on rotated screen without any extra efforts by Canola team. These guys are doing a great work and I believe that as soon as possible they will release full support for vertical screens.

You can test it installing Canola and following Jott instructions to install xrandr and Xomap screen rotation support.

Have fun.

Impressions and INdT13 Mar 2008 09:29 pm

It is great when you can contribute to others work. It is amazing to have access to the code, read and improve it.

But it is amazing when you see that there are other people improving your own work.

Jott has improved my Linux patch for Xomap Rotation and created an applet to make our lives easy when rotating. Take a look at his install instructions.

I hadn’t published my compiled kernel and .deb packages for chinook yet because I found a bug when switch screen on after automatically switch off, but Jott’s patch has fixed it. :)

Thank’s Jott.

$ cd `pwd`

Birunko saw I typing this command and asked me: “Are you crazy?”

I believe that the best answer for that question is: “not yet”, because in a single day I used:

  • gcc to compile gcc
  • wget to donwload the wget (source package)
  • find to find the findutils package
  • tar to unzip the tar package

(hmm it remembered me that another day I used apt-get to reinstall apt package that was corrupted)

So, what is the problem about to use the ‘cd’ command to “change” my current directory to my current directory?

ok, let me try to explain that. I was using 2 terminals. In the first one I had OpenEmbedded building Mamona packages and in the second one I was seeing the files generated on work directory. During the build my directory was deleted and recreated by OpenEmbedded, but my second terminal couldn’t know about that. The ‘pwd’ command still returns the full link correctly, but ‘ls’ and other commands tries to access something in memory that doesn’t exist anymore, so ‘cd `pwd`’ command takes me to the right current directory in memory.

But, if you thought that my strange day had a happy end you were wrong, I finished my day finding a bug on a bug tracker.

So the current question that is driving me crazy is: “how can I report a bug tracker bug in a bug tracker that has a blocker bug?

I couldn’t have a better end, could you?

Today I read an email from Quim Gil where he was saying that a distro is a lot more than code, there are humans around it.

I completely agree with him. But I’d like to add that in a distro there are human believes, human expectations and human sweat.

There is no distro without believe. When someone decide to make a new distro he believes that it will be someway useful and somehow better than others that already exists. So this guy (or company) expects to do something with his distro. He expects to fill a need. After this job was started people start to believe (or not) and to expect something of his work.

I’ve already heard “Why there are too many Linux distributions? It is so complex, why don’t you join efforts and code just one distro?”, but the answer for that is quite simple: Humans are complex. We have different needs, different expectations and different believes so we code different distributions. It is completely normal.

But, there is no free lunch. Code a new and different distribution isn’t a very easy job. You need to work hard, and every help are welcome. Mainly from those who believes.

What I want and need to say is that if you believe and expect something of this new distribution, please, contribute. This kind of contribution that makes the free software community even better.

Finaly I’d like to say that I believe in Mamona, I expect that mamona will be used by community as a completely Open Source alternative and I’m working hard to code Mamona.

For those that don’t know yet:

Mamona is a completely open source distribution for arm that intends to be an useful and open SDK for Maemo platform. Running a simple chroot command you will easily have a complete arm distribution running in your pc emulated by QEMU (user-mode emulation).
