Collabora and Impressions and Intel and Maemo27 Jul 2011 07:11 am

During the last 2 years I worked for Collabora having Nokia as my client. There I was part of the Harmattan Product Performance Team working with Maemo/MeeGo for N9 and N950.


The N9 and N950 has been announced. They are just perfect. An amazing design with a great system. Now that I’m sending my proto back I’m already looking forward to receive my N950 dev kit to continue working with it.

I’m also praying for Nokia giving up on M$ and continue working with MeeGo! ;)


Collabora was one of the greatest things that ever happened in my life. It is the biggest open source consultancy company based in Cambridge-UK with developers spread all over the world. They are well prepared and organized to have developers doing their best from any part of the world, mainly from their home offices.

Thanks for everything collabora family. I’m going to miss you.

But now it is time for change.


Next Monday – Aug 1st I’m starting at Intel being part of graphics development team. I promise that I’ll continue posting on this blog some news about my work there.

No, it wont be necessary to leave São Paulo. I’ll continue living on this huge city going everyday to Intel’s office here located at Market Place.

I’m here in San Francisco attending the MeeGo Conference. As always it is good to meet and keep in touch with old friends and also meet new interesting people.

Unfortunately no mobile phone running meego was released as expected. But anyway I’m sure that MeeGo has a great future. By Now I’m installing the just released MeeGo Developer Edition in my N900.

If you are here come to Collabora Booth see our demos and drink some coke with us. Follow us in twitter @collaborameego and/or #collaborameego.

But if you aren’t here you can see some presentations at Enjoy it.

For the very first time the Linux Foundation is organizing the Linuxcon Brazil. It will happen on August 31th and Seeptember 01 in São Paulo city at WTC.

I’m already confirmed to do a presentation in Portuguese-br: A Maturidade do Linux no Mercado dos Celulares e de Serviços: Rumo ao Domínio!

I was also invited by Klaus Kiwi to participate of a mini-sumit to discuss about Linux development as a professional activity, which I’m not sure if it is already confirmed.

Helio Castro will  be there as well doing a presentation about Meego!

Ok ok, maybe you don’t want to hear what we have to tell there, but what about listen to Linus Torvalds at this keynote ;)

I’m pretty sure that there will be other good presentations and talks over there.

See you there?

To whom didn’t know I’ living in São Paulo city now. When I was looking to apartment here I was using the Nokia maps at my N900 to guide me trough the streets that I didn’t know.

Well I cannot blame Nokia maps hard because it really helped me to find lots of places in this huge city.
However, last month I bought a simple Garmin Navigator (Nuvi 1053T) and I have to write that developers have a lot to learn with Garmin, regarding to the usability.

The usability was the main reason that I’ve chosen this brand instead of the other one available in the market. At this point you must be willing to ask me:

“if Nokia Maps at your N900 helped you to find all places you wanted when looking for a new apartment, why the hell did you spend money in a navigator?”

Well, for some reasons:

* Due to the Murph law, always during a decision taken the phone rings and I got lost :(
* After get lost my Nokia Maps didn’t recalculate the route by itself
* When the 3G internet was slow it was a pain to wait to see the maps and the path (Ok I know that there is solution/workaround for this issue)
* It doesn’t warn me when there is speed camera

and the main reason:

* My wife didn’t like the Nokia Maps usability and couldn’t use it very well and since I work at home she will use more the Navigator than me.

Well, due to this reason I’ve started to take a look to different brands and models.

The first one that I’ve played with was a Tom Tom of a friend. I didn’t agree with
the most of path it took and I saw that this friend and I had some difficulties to use it even been computer engineers.

Later,  I played with a my cousin’s garmin. Well, he is a smart and intelligent doctor but he admit that he can’t use computer and other electronic devices so well.
Although he got his garmin and use it so easily that I couldn’t believe. I had also agreed with most of the paths and than I was almost decided to buy one of this.

When I was in a store in Finland looking for a Garmin to buy I found a demo device on the shelve but it was in Russian and even in a complete strange language I could with few taps
to change the language to Portuguese and use it very well.

Then, obviously I bought it.

So most of my problems I had with my N900 in São Paulo streets have already been solved. But this is not the main reason that I decided to write about it.

I believe that all developers should learn a little bit about its interface.

= Developers in general

* Leave the interface as clean as possible. On the map screen there is few information; next step with street name, distance and directions and the map itself. It also doesn’t show the small streets when it is not really necessary.
* Use few buttons as possible. On the main screen there is only two buttons: “Where to go” and “Settings”
* is it touch screen? So prepare it for fingers. Really. Use big icons. If you have to get a pen to touch it is simple wrong. As a friend of mine would say: It is so 5 years ago.
* Use meaningful buttons so people can use even in strange languages.

= To the Navigator developers

* Recalculate route is essential
* Talk and speed cameras are not easy but important
* If the device is for multiple usages, add an option that allows it to ignore automatically incomming calls or other service when you really need the navigator.

The N900 is the cellphone that I’m using since last December and I simply love it. No I’m not a Nokia fun boy, I let this kind of behavior for those who loves design despite of usability, connectivity, reliability, etc..

Well, but as the title suggests this post is just for the N900 users ;)

As you should know the weakness of this device is the battery when you use so much 3G, wifi, bluetooth and GPS. I have to recharge my device every single night to be sure that I’ll have enough power for the whole next day.

At least I had, before to find out the Autodisconnect tool. You configure it to disconnect everything that is not really being used and is saves battery.

Well it doesn’t do any miracle but at least nowadays I can forget to recharge one night without being worried during the next day.

OBS: I’m not a Autodisconnect tool developer and to be honest I’ve never seen its code. This is just a tip for the users.

“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…

It has passed a while since my last post here, but nothing better than great news to get back to write.

I’m so proud to announce the Mamona 0.2 release.

The entire team has been doing a great job spending efforts to make it usable and stable, providing new installer scripts and new packages; supporting new machines; writing a better documentation and many other features.

Please, read the complete feature list at Mamona 0.2 Release Notes.
