El último viernes de Julio se festeja el dia del administrador de sistemas (sysadmin).
La idea esta muy buena y aqui paso tambien a transcribir la definición de que es administrador:

What is a System Administrator
An individual responsible for maintaining a multi-user computer system, including a local-area network (LAN), wide-area network (WAN), Telephone system, or voice-mail system.

 See Figure 1.

Typical duties include:
Adding and configuring new workstations
Setting up user accounts
Installing system-wide software
Performing procedures to prevent the spread of viruses
Allocating mass storage space
Answering questions
The system administrator is most often called the sysadmin, or S.A., or just the systems administrator. Small organizations may have just one system administrator, whereas larger enterprises usually have a whole team of system administrators

Esta muy interesante el sitio oficial, si sos administrador o tenés un administrador conocido, hace pasar la bola.
