Kubuntu Install Fest in Salvador, Brazil

ENG:

Continuing the efforts to make a great and userful ( not only for documentation writting ) opensource community in brazil, the C.A ( Academic Center ) of my university is promoting withthe help of a great colleage of mine, André Brasil Wyzykowski. There will be mini-courses and talks, and for something different, not all talks will be for those that already know what OSS, but also for the side of society, like Psichologists, Lawyers and Administers that are not on the IT area. with 2 mini courses ( Using Kubuntuu for the non initiates ) andother, probably Qt or Python, and 3 open slots for talks.

It’s good to see the community growing.

Live Blue techbase & userbase sprint

“To compile kde from trunk (soon to be kde4.1) the latest Qt4.4 snapshot must be compiled from source.”
taken from one link on ‘building from trunk’ on techbase.kde.org, aparently it needs a bit of love.
tomorrow the people from live blue ( Me, Sandro Andrade, Henrique Watt, Vito, Cibele Vasconcelos and a few more ) will unite forces and remove do a big cleanup of old information, write about new things and do more translations to pt_BR.

I will, also, add a section on the techbase for the kdesvn-build, since it’s really easier to start building kde-trunk with it.
if anybody has any comments of places on techbase and userbase that needs improvements, please, state it on the comments and I will take a look carefully.
there will be 8 persons writing documentation from 1p.m to 5:30 p.m
and probably many more to come.

Kde Open Talk, Pictures o/

Success, if one word can describe it. It was the room fullest of geeks, nerds, opensource evangelists and a cute girl. that`s also an open source evangelist.

the talk started late, the room was being used for a normal class, so we waitedd outside for about 30 min ( sorry, no pics of this ).

so we moved inside the room, and things started.

This is Sandro Andrade, talking about Qt development. the one behind him is me. ( hello me. o/ )

almost impossible to see the slideshow, bad camera flash, bad camera flash. thow are a good person but this kind of behavior is not accepted by mankind.

me, in all my glory, talking about how to help kde if you don`t want to program, and who you should be afraid on #kde-cafe.

keep talking tomaz, nobody is hearing you, blablablá.

It was almost 50 people in the room. in a event that was not even well – advertised. neat.

Yes, I sit on the table. and no, I don`t care.

Rato and Cibele, the cute-couple of the FOSS movement in Bahia. ( hello hato, cibele, you are now on planet. o/ )

Remember the logo? it`s now on tshirts ;D

Thanks for your suporte Xande. ( that`s shandee )

that`s all folks. =D

… but live happly

Today I’m annoucing a new KDE-users ( and also coders and documentation writers) group.

Since my university killed the OSS movement inside it 1 year ago, like a phoenix it’s comming from the ashes.

In portuguese ‘blue’ has a completely different meaning from English, it means ‘Nice’ and ‘Cool’,

So, with no more round ups, I present you the new KDE-Users, Coders, Artists and Documentation Team from Bahia, Brazil, ‘Live Blue’.

Initially it has 9 members from more than one university, and 2 projects. Armina ( a code-visualization tool ) and Rocs ( that one day I will finish it… )

The logo was made by Alexandre Freitas,  ( xandolino at gmail.com ), and I encorage everyone to send him a ‘thanks’ and a ‘come on, and meet the artists team’, this is not his first job for kde-related stuff, but mostly I poke him to help me with graphics ;D

Cyao people, tomorrow is calling me to bed.

Qt/KDE openTalk on UFBA, Brazil.

EN:

Next friday there will be a open talk about kde development shedule, kde technologies and qt on the Federal University of Bahia ( UFBA ) with me ( Tomaz Canabrava , undergraduated bachelor in computer science student) and Sandro Andrade ( soon-to-be-PHD ). It’s good to see the number of open-conferences growing in Brazil.  ( the pt_br text is not a translation of this one, since they need more information if they want to go ;D )

PT_BR:

Próxima sexta feira, eu ( Tomaz Canabrava, bacharelando em Ciência da Computação  ) e Sandro Andrade ( Doutorando em Projetos de Software ) iremos fazer uma apresentação aberta na UFBA, no campus de ondina ( pavilhão de aulas da federação, que não sei porquê fica em ondina) estaremos apresentando uma palestra aberta sobre Qt e KDE. será no IM ( Instituto de matemática ) a partir das 3:30 da tarde, dia três. ( 03/abril )

Apareçam.

Win. (Thanks people) – Linux in the labs. ;D

So, After my frustration post I got around 2.000 visits, a record for my humble blog.

gathered some comments,  and mailed the university that plus a bit of research.

the result: I got a working lab with linux machines on it, running KDE 4.2 – no matter what distro

and My coordinator told me that the university will try this year a program of capacitation in FOSS including (but not just) courses for OSS API’s such Qt and KDELibs and a few more surprises that will come in time.

seriously, thank you.

KDE in nearly all public schools in brazil.

Today I was in a public school near where I live for a interview with Nazareth, the coordinator of a social-inclusion project for the less afortunate kids in brazil, that live in 2 poor-communities: Alto do Coqueirinho and Bairro da paz.

What do you plan to accomplish with your project?

The students here have many needs that their family cannot provide, there’s a lack of love, lack of knowledge and everything that is happening to them is weird, they don’t talk about it at home, and the school should provide some shelter.

But what has linux to do with this kind of thing?

I Feel in love with linux the first time I heard about it. all kids that live near hear doesn’t have the money to buy computers, and nowdays it’s really important to be part of the digital-inclusion for jobs and such. they usually uses the computer for playing, but some are already trying to make their homework using it. The government send us those machines, they had linux pre-installed, we have 20 machines here. it’s a small lab, but each windows copy is almost half of what a teaher gets per month, so it’s a lot for us. with linux, we are free to install and teach.

What about the Teachers, how is getting used to linux fells to them?

They hated at first. they are teachers that doesn’t like to learn new things, they don’t take advantage of the teaching tools ( and, to be fair, they don’t take advantage of the natural curiosity of the kids neither ). so it’s being rougth, we have asked some people from the government to came here and give a crash course for the teachers, but that wasn’t enougth. dealing with teachers that don’t wanna learn is hard.

How many students are going to use those desktops?

about a hundred.

And are all other public schools using desktops with linux?

Yes. it’s a big program. nearly all public schools got a lab with 20 computers and this linux preinstalled.

Can I take a look at the machines?

sure.

about the machines: to be fair, this was not so nice… the machines are a modification of Debian linux, named Educacional Linux ( linux for education), running 2.6.18 kernel and KDE 3.5.5, the /etc/apt/sources.lst was empty, and the aptitude and apt commands removed. I don’t know why the government did that, since the hability to upgarde is good in any system. But it’s really great to see that the government is doing what they promissed: digital inclusion in every school.

Usability ( or why my app is not ready yet.)

For those that don’t know me yet, I’m trying to make a good app for Graph Theory study. it has few goals, like the ability to draw graphs and the ability to program the graphs with algorithms and execute the algorithms to see the results. I’v managed to do a working ( but very ugly ) app in ~ 2weeks, and people in my university used it, I was kinda happy. ;D

Rocs first Version

but as you see, this version was ugly as hell. so I start porting it to Qt only to KDE libs, and my first version was like this:

that time I was trying to use Kross. my original implementation was in QtScript and I wanted more languages than just ECMAscript running on it. Now the program has this looks:

But it’s still QtScript only. I Know that Kross should be easyer to use and stuff, but I think I’m a kinda retarded, I couldn’t make it work no matter how I tried ( and I think I almost drove Apol crazy on irc. ;D ) Goals for this year: Finish the JavaScript implementation and after that try to help kross guys.

Frustrating

A bit frustrated by my  university this year.  Last year 100% of the computers where running windows, but since I got elected for representing the Computer Science students, I did a meeting with the principal and he allowed me to have 4 labs with Linux  running. I did another meeting with the students, choose a distribution (  between fedora, kubuntu, mandriva and suse) and  some programs that we needed, burned the CD,  and did a small shell script to  install everything that we choose, and mailed to the computer management section. this was last november.

Last friday I went there to see how was going the installation of the 4 labs, and they just had one machine installed,
without  all programs that I’v asked ( there’s no point in having a linux installed for computer science classes without a compiler ). so I tryed to use firefox to send an e-mail with a few nasty words to them, but I couldn’t. The internet for linux was blocked. I was in shock. the excuse was “it’s easyer to hack the system with linux, so we decided that linux labs will not have net access”. Way to go.

the machines where running unecessarily slow, they had formatted everything in FAT32. argh.

Another  reunion with the principal, I manage to get networking on the linux labs, asked them to reinstall everything right using an ext3 partition ( for some reason I dislike raiserfs. ) and installing  my needed software.
One thing that I really  don’t got it, is that the university has 11 computer labs, and *every* semester they reinstall ALL windows,  but they didn’t have time to  install 4 labs with linux?

Ps. There’s a lab with 4 windows in each machine.
Frustrating.

Latex file for Kde-Qt code coloring

Hey all. 

I was lost a few days on the land of the strange latex files, trying to do some code coloring on it. the thing that I`v seen that worked almost, but not quite I was expecting was lstlistings using c++ as the default language. after a bit more of a research, I found a `C coloring in latex with tango` and a few other projects that translated the code into a non-compreensible-to-humans format that could output color to latex generate pdf.

 

Well, Suffer no more. I humbly give you all my modification of the C++ language on the lstlistings package that pretty colours your code.

OBS:. the file is .tex, I just changed the extension to .png so WordPress will let me upload it. please, rename it to .tex  

The file: 

(remember to rename it kdetex.tex)

and a PDF that I used this thingy.:

livro

to test it, just put the code into a lstlisting block.

Comments, Tougths?
