Overview
The course aims at starting the students off on programming system applications (e.g. a server) on a UNIX® System.

Learning Outcomes; after the course the student should
* Know the most important functionalities and facilities offered by a UNIX® system, the System Calls (and, more generally, the APIs) offered to access them.
* Be able to write efficient CLI (Command Line Interface) system and network applications in the C language.
* Know how to write interoperable applications by complying with the UNIX® standards (SUSv3, SUSv4).
* Know which are the main differences between the MacOS and the Linux varieties and how to cope with them.

The course is strongly oriented towards an hands-on methodology. Students must follow lectures in front of a computer which must be used to reproduce and test what is explained by the teacher-

Writing a C program aimed at solving a given problem within a given time. Students are free to consult (paper and digital) texts and to use Internet search engines.
