Hi everyone,im a young boy who recently discover this web, and i want to test if it works fine.

As i can see there are some topics like Chat Room, Corrections,etc.

I would like to write about my university,it is very cool,it have three floors conected by a elevator,there are a lot of laboratories, and computer rooms for researching about robotics and mind control (haha).

Today i made a test about low level programing,at first sight it seemed easy,translate some functions from C (a programming language) to assembler,but the last exercise was a litle dificult that i tought,my code doesnt works correctly, i feel bad about it.

thanks for read.
