Venezuelan researcher has set a new Wi-Fi distance record

June 19, 2007

A researcher from the Universidad de los Andes (ULA), Prof. Ermanno Pietrosemoli, has set a new record for the longest communication link with Wi-Fi: 382 kilometers (238 miles). Pietrosemoli, president of the Escuela Latinoamerica de Redes (or Networking School of Latin America), achieved the record by establishing a Wi-Fi link between two computers located in El Aguila and Platillon Mountain, Venezuela. Pietrosemoli gets about 3 megabits per second in each direction on his long-range connections.

It is important the creation of software, our software, free software…

November 12, 2006

With this words the Venezuelan President stressed the importance of the new National Centre for Research and Development on Free (as in Freedom) Technologies (CENDITEL). As the President puts it: “The centre will be key in achieving our scientific/technological independence”. Moreover, the centre is part of a National Initiative to create and guarantee access to knowledge because according to the Venezuelan President: “knowledge is universal. It is like the sunlight, nobody can say the sunlight is mine”. Knowledge does not belong to an individual (or group of individuals) it belongs to the entire human race.

The new Centre will focus, during the first year, on developing free and open source software for:

  • the public administration,
  • PDVSA, and
  • the groups for local development.

Starting on the second year of operations the Centre will expand his focus to include free and open hardware and bioinformatics.

Back from the IV World Forum on Free Knowledge

October 23, 2006

Yesterday, I got back from the IV World Forum on Free Knowledge. It was an amazing experience. I had a good time even though I was part of the organizing committee 😉


People were really interested in the democratization of knowledge. Besides my participation as an organizer, I gave a talk on Free Science: Utopia or Reality?, I gave a tutorial on Image Analysis and I chaired a Panel Discussion Session on Intelectual Property in the XXI Century. Some time in the next couple of weeks, I will comment on my experience in the Forum. For now, I just want to comment that Perl was well represented in the Forum with three out of the seven tutorials that were offered “free of charge” having something to do with Perl. The three tutorials were:

  • Introduction to Perl with Randal Schwartz
  • Image Analysis with Lino Ramirez, and
  • GUI Development with Perl with Alejandro Garrido



A Beginners Guide to Fuzzy Rules-Based Systems

October 12, 2006

I just finished writing an introductory tutorial on Fuzzy Rules-Based Systems with Perl. I posted it on the Perl Monks’ website. This tutorial is part of a larger tutorial I am giving at the 4th World Forum on Free Knowledge this coming week in Venezuela.



Perl Monks, Granular Computing, and World Forum on Free Knowledge

October 1, 2006

Some days ago, I attained level 3 (Acolyte) in the Perl Monks. It is nice to see how my opinions are getting good reviews 🙂 . These days, I am working on a Granular Computing tutorial for the Perl Monks community. I plan to divide it into two posts:

  1. General Introduction: from information granules to granular computing; applications: image processing, data mining, signals processing, etc.; common frameworks for Granular Computing: Interval Analysis, Fuzzy Sets, Rough Sets; and finding information granules in a Fuzzy Sets framework.

  2. Plan for a Granular Computing Module: here I present what modules are needed in Perl to write a Granular Computing Module. My idea is that we should create several (small?) modules and combine them to create the Granular Computing module. For instance, we could have a Fuzzy Sets Module (there are already some modules in CPAN related to Fuzzy Sets, so our task would be to chose one and improve it), a Rough Sets Module, an Interval Analysis Module, and a Clustering Module (I already wrote a Fuzzy C-Means script, I certainly would be happy writing all the scripts needed in this area). Our Granular Computing Module would call on these modules and add some additional functionalities. The advantage of doing it this way is that if someone is interested only on an individual module (Fuzzy Sets, Interval Analysis, etc.) that person would not need to use the whole Granular Computing Module. Moreover, I expect it to be easier to maintain smaller modules. The only problem I see with this idea is related to dependences. In any case, I guess that I will be writing a lot of Perl code this coming year 😉

The last point on this post is related to the 4th World Forum on Free Knowledge. This Forum will take place in Maturin, Venezuela from October 17 to October 21, 2006. In the Forum, I will be giving a talk titled: Open Science: Utopia or Reality? In this talk, I describes what is needed to have a truly open science, muse on whether Open Science is attainable, and present some guidelines to help us make it a reality. In the Forum, I will also give a tutorial on Image Analysis using Free and Open Source Software. The tutorial focus on my research in using Granular Computing for image analysis. I will describe my experience with the ITK and the Perl’s AI::FuzzyInference module in my quest for finding a way to help content experts in analyzing images. I will post more on that later.



OSCON Recap Part III

September 22, 2006

Here is the last part describing my first visit to OSCON. Before I start, I have to thank O’Reilly for giving us the opportunity to talk about the Venezuela’s quest to achieve technological independence. Second, I have to thank Jeff for the invitation and his hospitality. And of course, I have to thank Chris for letting me stay at his place.

On Friday we gave our talk to a group of social activists in Portland. It went quite well: Alejandro had plenty of time to give his portion of the talk 😉

People were quite engaged and we hope the message went across. The audio of the talk is available here thanks to Chris.

Finally, I leave you with the note inviting to our talk




OSCON Recap Part II

September 22, 2006

I have been so busy with my research and helping organize the 4th World Forum on Free Knowledge that I did not have the time to write down my thoughts about OSCON until now. Anyway, I will do my best to give you a short description of what our session was about.

Our session name was: Sofware Libre: FOSS in Venezuela. We had a decent number of attendants considering that we were targeting people interested in the social aspects of Free and Open Source Software in a conference where the business aspects were king.

Jeff gave a not so brief introduction to the Venezuela’s efforts to move to free and open source software and then I started my talk. Some how I got carried away and started talking for a longer time than we agreed to. This left little time to Alejandro to talk about the project he is working on to make more human-friendly the prisons in our country.

In short, we got some nice reviews, specially this one. We hope people enjoyed the talk while learning about what is happening in Venezuela and how that relates to the global Free and Open Source Software movement.

For those interested, I posted the slides of my talk here.
