My open source journey: From Pong to microservices
In 1990, I was a 9th grader living in Vietnam. I had never had access to a computer. One day my mother returned from a trip and gave me a book titled "How to program with Turbo Pascal." I was delighted—everything I read in that book made sense, and I started to write code on paper.
When the local university opened a computer lab that offered rentals, I spent all of my allowances for weeks, trying to write the classic Pong game in Pascal.

I used what was known as a "TV-out" card, which had an extra output to connect to a standard television set. The onscreen result didn't look very nice and there was no audio output. And it was ugly: I had an S-Video cable running across my living room floor to my 19" Sony Trinitron CRT TV set.
How to test your network with PerfSONAR
PerfSONAR is a network measurement toolkit collection for testing and sharing data on end-to-end network perfomance.
