Searching for your Open Source code

This can be something that can make you proud in the morning :-) Basically, try searching on different code search engines for your name, and see the results! I’m sure you will be impressed with the results… Here are my results: Google Code Search: <a href="http://www.google.com/codesearch?hl=en&lr=&q=%22ruben+fonseca%22&sbtn=Search">Search public source code for Ruben Fonseca</a> Koders Search: <a href="http://www.koders.com/default.aspx?s=%22ruben+fonseca%22">Search public source code for Ruben Fonseca</a> Krugle Code Search: <a href="http://www.krugle.org/kse/files?query=%22ruben%20fonseca%22">Search public source code for Ruben Fonseca</a> Show me your results :-) (idea stoled from <a href="http://coreygoldberg.blogspot.com/2008/07/searching-for-your-open-source-code.html">Corey Goldberg blog</a>) 109 searching-for-your-open-source-code

Searching for your Open Source code Something like 2-3 years ago, I started a small project with my friends called <a href="http://cshare.sourceforge.net/">CShare</a>. From the site you can read: <blockquote> cshare (from console share) lets you share any directory through a HTTP server. it’s simply to use (just launch it from the terminal), fast (multi-threaded POSIX), personalizable (XSLT themes), and client plataform independent (you just need a browser). </blockquote> We started the project because we wanted to write some elegant code with a modern C style, and do some experimentations on bleeding performance under the Linux environment. Although we wrote tons of code (it’s still available on the SVN repository), the application never saw the light of the day, mainly because we felt a lack of motivation due to the slow development speed with C. So we’ve completely abandon the project. I’ve also tried 2 or 3 times to completely remove the project from <a href="http://sf.net">SourceForge</a> with no success: the process is beyond bureaucratic… However, the reason I’m writing this post is because I found today a simple way of getting the same functionality of CShare, with a <a href="http://www.debianpt.org/node/1693">single line of Python</a>: <pre> python -c "import SimpleHTTPServer;SimpleHTTPServer.test()" </pre> Even tough you will not get the same performance and concurrent access like CShare would (eventually) deliver, it’s simply enough to sit at your <code>.bashrc</code>, and it really gets the job done! 108 cshare-in-one-line

CShare in one line My current laptop has a beautiful piece of crap of an <a href="http://ati.amd.com/products/radeonx1600/index.html">ATI Mobility Radeon X1600</a>. At first I installed <a href="http://www.ubuntu.com">Ubuntu 8.04</a> on it and immediately switched to the proprietary ATI driver (to get more features and better support for multi-head). However, the display always seemed sluggish.. I never use 3D or Composite, it all seemed related to 2D rendering. For instance, when I switched workspaces I often had to wait 10 seconds for windows to be redrawn. Still, I managed to work like this for a while. One day however, I decided to try the <a href="http://dri.freedesktop.org/wiki/ATIRadeon">open source drivers</a> (it seems they have initial support for the R500 chip on this graphics board). The good news is that is supports multi-head profiles far better than the proprietary driver (<a href="http://www.x.org/wiki/Projects/XRandR">XRandR</a> 1.2 FTW!). Still, the 2D sucked, got no 3D nor XVideo overlay… I even thought “oh this must be an Ubuntu thing”... At the beginning of this week I managed to install <a href="http://www.debian.org">Debian</a> Unstable on this laptop, but had the same problems using the open source “radeon” driver…. On a desperate move, I’ve tried the latest and bleeding edge ATI proprietary driver. For my surprise, all my problems were solved and the card is working properly! So I decided to log here the steps I took to get the things properly (remember, I’m running Debian unstable). <h3>Instructions</h3> First, we have to download the latest drivers from ATI from <a href="http://ati.amd.com/support/drivers/linux/linux-radeon.html">their website</a> Then as root run: <pre> ./ati-driver-installer* --extract fglrx cd fglrx ./packages/Debian/ati-packager.sh --buildpkg sid cd .. dpkg -i *.deb </pre> This will build <code>deb's</code> from the ATI distribution file and install them or your system. The next step is to build the actual driver, and for that you can use module-assistant like this: <pre> m-a prepare m-a update m-a a-i fglrx </pre> This will build and install the <code>fglrx</code> driver for your current installed kernel. Then you must configure Xorg. I followed this steps: <pre> aticonfig --initial=dual-head --screen-layout=horizontal </pre> After this I just started X and it worked perfectly. I mean, I had horizontal BigDesktop, fast 2D rendering, 3D, XVideo overlay on both displays and suspend is working like a charm. The only problem left is that my second display has a bigger resolution that the main one. However, the ATI driver sets the second display to the same resolution as the first. To work around this problem I just had to manually edit <code>/etc/X11/xorg.conf</code> and add at the <code>Section "Device"</code> this: <pre> Option "Mode2" "1680x1050" </pre> Replace the resolution with the native resolution of your second display. Restart X and BANG, it should work :) Hope that this instructions can help you somehow. 107 solving-2d-rendering-problems-on-an-ati-x1600

Solving 2D rendering problems on an ATI X1600 This is my side of the story about the <a href="http://fct.enses.org/barcamp/app/">BarCampFCT</a> event. First of all, congratulations to the organization for selecting a great place to make the Barcamp. I never went to the <a href="http://www.fct.unl.pt/">FCT UNL</a> before, but I loved the peace, the view and the weather. However, next time try not to do a Barcamp on a amphitheater.. it kills networking! The day began with a slow start… The poor guy talking about <a href="http://firehol.sourceforge.net/">FireHOL</a> had the duty of waking people and do the kick off. Next talk about technique presentations by João Rico started well, but quickly became boring. I had to get out of the room and search for some coffee… This was actually a good idea, because at the coffee break room, it was happening a lot of networking! Kudos for the cookies and the coffee, they were great! This happens to be the first time to know people and mingle around. Next it was the lunch… the lunch was perfect. Perfect. Perfect. Congratulations for this! <a href="http://wizi.com/">Wizi</a> arrived late, and managed twice to almost kill the barcamp. On their first talk, they asked for 5 minutes, and delivered some 20+ boring talk… Can’t help it… But then there was <a href="http://artofsystems.blogspot.com/2007/01/halfbakedcom-entrepreneurial-improv.html">halfbaked</a>! Lot’s of great ideas about creating a new company, and lots of laughing too. Great time! <a href="http://www.tarpipe.com">TarPipe’s</a> didn’t disappoint, although I was expecting a more practical talk about the service (/platform/product). After more coffee and cookies, it was time to IGNITE! First I have to say that ignite sessions should have been done earlier, and the organization should be more fair and respect the speakers. Some got 10 or 15 minutes, some got 5 with auto rotating slides (killing the presentation), and then Wizi destroyed all the ignite spirit. I managed to get 5 minutes auto-rotating slides and talked about “Debian Sucks” (it doesn’t, really!) and the OpenSSL fiasco. Overall it was a great day, the organization deserve a great applause! I’ve got some good conversations, new ideas, met new people, and learned how a company (Wizi) can easily generate some bad buzz at an event. 106 barcampfct-my-side-of-the-story

BarCampFCT, my side of the story Together with <a href="http://whythehype.com/">Tiago Pinto</a> I’ve completed a <a href="http://www.tarpipe.com">TarPipe</a> <a href="http://tarpipe.rubyforge.org">API for Ruby</a>. <blockquote> tarpipe is a publishing mediation and distribution platform that simplifies regular upload activities </blockquote> The gem is available <a href="http://tarpipe.rubyforge.net">here</a> and the sources are on <a href="http://github.com/rubenfonseca/tarpipe-ruby/tree/master">github</a>. It is my first released gem so feel free to send some tips and suggestions. TarPipe is currently evolving very fast so me and Tiago will make sure our library stays up to date.
