The GPL v. 3 is Here

June 30, 2007

The new version of the GNU GPL (General Purpose License) was unveiled on Friday June 29, 2007. The complete text is available at the GNU GPL site. How many projects will switch to use the new license? That is a question that only time can answer …

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.

Is Canada a Land of Mediocrity?

June 17, 2007

The Globe and Mail reports:

Canada’s failure to innovate is spilling over into the economy, environmental protection, health care, education, and poverty eradication – turning the country into a land of stifling mediocrity, according to a harsh new report card from the Conference Board of Canada.

Even though I do not agree with the title of the article, I completely agree that we (specially our Government) need to do something to move forward our beautiful country. We have the people and the talent, we just need the support of our government to create an environment in which innovation could flourish.

Generating cool fractals

June 16, 2007

This one is from the Free Software Magazine. Xavier Calbet wrote:

Whether you are a professional or amateur scientist, engineer or mathematician, if you need to make numerical calculations and plots quickly and easily, then PDL (Perl Data Language) is certainly one of the best free software tools to use. PDL has everything that similar high-level, proprietary, numerical calculation languages (like IDL or MATLAB) have. And it certainly comes with all the features you would expect to have in a numerical calculation package.

Machine Learning Made Easy with Perl

June 15, 2007

That is the title of a session I am giving on July 25, 2007 at OSCON. Here is the abstract:

Machine learning is concerned with the development of algorithms and techniques that allow computers to “learn” from large data sets. This talk presents an overview of a number of machine learning techniques and the main configuration issues the participants need to understand to successfully deploy machine learning applications. The talk also covers three case studies in which we will use Perl scripts to solve real life problems:

  1. Medical decision support systems using support vector machines
  2. Exploratory financial data analysis using fuzzy clustering
  3. Pattern recognition in weather data using neural networks

This talk offers an intensive presentation of machine learning terminology, best practices, standard process, and strategy. Participants will get to know the techniques but more important, they will learn when to use them and why to use them. The talk is appropriate for educators and programmers who want to use machine learning in their own problem domains.

I will be posting more details about the session as we get closer to OSCON.

Cheers!

Microsoft Signs Patent Agreement with Another Linux Distributor. Is this the beginning of a trend?

June 14, 2007

Last year, it was Novell. Early this month, it was Xandros. Early this week, it was Linspire. Who will be next? And more importantly: Is this the beginning of a trend?
