Hi, I am writting document in spanish about UNIX programming because I have
found that south american universities are focused on Windows, The students
and teachers think the computer science is Windows, they dont know others
OSes, They dont motivate students to understand OSes internals, I dont
understand Why the degree is "system engienering" if they dont know about
memory manipulation, threads, procress, IO, debuggers, etc.
Why study 5 year of engineering if they will work doing clicks and running
'wizards' ? Where are the south american researcher?, Where is the curiosity?.

I read a documentain that describe signals and It says there are 4 types of
'signal handling enviroments': BSD, SysV unreliable, SysV reliable y POSIX.
What does that means? What are those 'enviroments'?
How can I know which enivorement use certain OS ?
What is "POSIX"?

Also, I am trying to cover all UNIX-like oses in my documentation (HPUX, aix,
sunos, DGUX, *bsd, sco, linux), I'd like to know What is the best computer
science-oriented way to call all those OSes? "Unix based OSes", "Unix like 
OSes" or just "UNIX" ?

bye friends!.
