Linux I LOVE Linux. Strange? Of course not. My favorite distribution is RedHat 6.1. For those of you who like programming I'd suggest to try Glade GUI builder for X Window with Gtk. Look at my Favorites.

Micro controllers Currently I experiment with Microchip's PIC16F84 and I'm delighted with the capabilities of this tiny controller. If you are interested, you can look at some of my  projects. If you are getting started with PIC16F84, find out how I do the job.

Packet Radio That's my favorite ham activity. I use mostly Eskay Packet SP 9.75, TstHost 1.43b, Yaesu FT-411E and 6-el yagi.

Optimization That is my basic interest at the University, especially following fields: Linear Programming, Nonlinear Programming with iterative procedures, Dynamic Programming, Estimation and Optimal Control. Most recently, I am researching application of genetic algorithm of optimization in training of backpropagation neural networks.
