A few days ago, I was invited to "SefroYek" a technical TV show that discusses with experts. That was second session and I've been there to talk about “Open Source operation systems”. I opened the discussion with GNU/Linux. Next, I answered the questions. There were many questions about equivalent windows softwares in GNU/Linux. I uploaded the first part. It’s in Persian language.
I've wrote more information about this TV show in my Persian blog.
Have a good time ;)
