More on Peter Sunde, Stallman and Lula

Pablo Lorenzoni on his blog, Nardol, has two good posts on Brazilian President's visit to FISL.

The first, explaining the preparatives for the presidential visit on

FISL10 day 21

And the second telling about the visit itself, on:

FISL10 day3 - the day I met the Presidento

This one, specially, had two good parts which deserves note, the first is the picture which shows what I had told on "Stallman and Pirate meet Brazilian President":

At the front layer, you can clearly see, from left to rigth, Peter Sunde (green jacket), Richard Stallman (red shirt) and Mr. Luiz Inacio Lula da Silva, the Brazilian President.

And the second part from Nardol, is the transcription of part of the President's speech, which I do reproduce here:

“I remember the first meeting we had at Granja do Torto [which is the presidential country residence – similar to Camp David, but less aristocratic], in which I understood absolutely nothing about what these people were discussing, and there was an enormous tension between those defending the adoption of Free Software by Brazil and those defending we should just do what we always did – remain the same, buying and paying for others’ intelligence. Thanks God, in our country, the decision to adopt Free Software prevailed.”

This was one of the most important parts, IMHO also.

uSleep on windows (win32)

I am facing a terrible issue regarding timing on windows. Googling arround, I've found those infos: Using QueryPerformanceCounter and QueryPerformanceFrequency APIs in Dev-C++ ( http://yeohhs.blogspot.com/2005/08/using -queryperformancecounter-and_13.html ) QueryPerformanceCounter() vs. GetTickCount() http://www.delphifaq.com/faq/delphi_windows_API/f345.shtml How to time a block of code http://www.cryer.co.uk/brian/delphi/howto_time_code.htm And Results of some quick research on timing in Win32 http://www.geisswerks.com/ryan/FAQS/timing.html With that I'm trying to write something like a uSleep function for windows: # include<windows.h> void uSleep ( int waitTime){ __int64 time1 = 0, time2 = 0, sysFreq = 0; QueryPerformanceCounter((LARGE_INTEGER *)&time1); QueryPerformanceFrequency((LARGE_INTEGER *)&freq); do { QueryPerformanceCounter((LARGE_INTEGER *)&time2); // }while((((time2-time1)*1.0)/sysFreq)<waitTime); } while ( (time2-time1) <waitTime); } T

More trickery with gnuplot dumb terminal

In my post " Plotting memory usage on console " the chart doesn't pan the data. Now, using a named pipe, the effect got a little bit nicer. First, we have to run the memUsage.sh script to get a file filled with memory usage info: ./memUsage.sh > memUsage.dat & Then we have to create a named pipe: mkfifo pipe Now we have to run another process to tail only the last 64 lines from the memUsage.dat while [ 1 ]; do tail -64 memUsage.dat> pipe; done & And now we just have to plot the data from the pipe: watch -n 1 'gnuplot -e "set terminal dumb;p \"pipe\" with lines"' And that is it!

The prefuse visualization toolkit

Navigating on the silk icons web site , I've found an interesting use of the Prefuse Visualization Tool Kit. “Prefuse is a set of software tools for creating rich interactive data visualizations. The original prefuse toolkit provides a visualization framework for the Java programming language. The prefuse flare toolkit provides visualization and animation tools for ActionScript and the Adobe Flash Player.” They have some nice visualizations on their gallery. I hope to soon use this tool kit on some projects on my job. Bellow is the screenshot of one of the projects which had used Prefuse: This particular screenshot is from the project: Voyagers and Voyeurs: Supporting Asynchronous Collaborative Information Visualization by ( Jeffrey Heer , Fernanda B. Viégas , Martin Wattenberg ) . Following Fernanda B. Viégas and Martin Wattenberg web sites, I've discovered that both worked on the Many Eyes project for IBM . Perhaps, Prefuse is the ancestral of Many Eyes... ;-) As is i
