GNU Plotting
gnuplot homepage
On advice from several friends, I've decided to learn gnuplot to produce graphics for my work.
Demos
Windows installation:
1 - Download Windows package (e.g. gp440win32.zip)
2 - Unzip to a folder (e.g. C:\Program Files\gnuplot)
3 - Define environment variables:
3.1 - (optional) GNUPLOT_HOME = C:\Program Files\gnuplot
Add %GNUPLOT_HOME%\binary to your PATH environment variable
3.2 - GNUPLOT_LIB=
3.3 - (fonts for PNG output) GDFONTPATH=%windir%\FONTS
3.3 - (fonts for PNG output) GNUPLOT_FONTPATH=%windir%\FONTS
4 - Open a new console window and type gnuplot.exe or wgnuplot.exe.
(see README.Windows for more information)

Java regular expressions testbed
Regular expressions are one of the most useful programming tools, particularly for text processing. Java has a nice implementation, stored in the java.util.regex package.
The following page by David Matuszek contains a Java Applet to test regular expressions. I use it a lot and recommend it!
http://www.cis.upenn.edu/~matuszek/General/RegexTester/regex-tester.html
Have fun!

Privacy policy for the social web
Let me make a point first: "Anything you post on the Internet is out of your control. Forever." This includes anything you search on Google, you post on Facebook, etc. Even if you use privacy settings, or even if you control the Web Server (which you usually don't), someone who reads your data can copy and share it, without your knowledge or consent.
However, there is great benefit in having a presence on the Web. You can let people know more about you and your work.
Just be aware that it is a public presence. So, don't say anything that you would not say in a public place for anyone to hear, for example, in a plaza or in national television.
My current social web policy is the following. I'm using:
- Email as a messaging service;
- Skype as a quick messaging service (sometimes with voice too);
- my personal web page as a "live" business card and CV;
- Facebook as a "live" address book;
- LinkedIn as a "live" business address book;
- Twitter as a quick sharing service;
- Blogger as a sharing service.
So, now you know what to expect from me online. See you around in a "plaza" somewhere ;-)
