Walau telat 1 hari gue tetep mo ucapin  Happy  SysAdminDay  buat para  System  Administrator  Seluruh  Indonesia (27 Juli) emoticon

A sysadmin unpacked the server for this website from its box, installed an operating system, patched it for security, made sure the power and air conditioning was working in the server room, monitored it for stability, set up the software, and kept backups in case anything went wrong. All to serve this webpage.

A sysadmin installed the routers, laid the cables, configured the networks, set up the firewalls, and watched and guided the traffic for each hop of the network that runs over copper, fiber optic glass, and even the air itself to bring the Internet to your computer. All to make sure the webpage found its way from the server to your computer.

A sysadmin makes sure your network connection is safe, secure, open, and working. A sysadmin makes sure your computer is working in a healthy way on a healthy network. A sysadmin takes backups to guard against disaster both human and otherwise, holds the gates against security threats and crackers, and keeps the printers going no matter how many copies of the tax code someone from Accounting prints out.

A sysadmin worries about spam, viruses, spyware, but also power outages, fires and floods.

When the email server goes down at 2 AM on a Sunday, your sysadmin is paged, wakes up, and goes to work.

A sysadmin is a professional, who plans, worries, hacks, fixes, pushes, advocates, protects and creates good computer networks, to get you your data, to help you do work — to bring the potential of computing ever closer to reality.

What Is MINIX 3?

MINIX 3 is a new open-source operating system designed to be highly reliable, flexible, and secure. It is based somewhat on previous versions of MINIX, but is fundamentally different in many key ways. MINIX 1 and 2 were intended as teaching tools; MINIX 3 adds the new goal of being usable as a serious system on resource-limited and embedded computers and for applications requiring high reliability

This new OS is extremely small, with the part that runs in kernel mode under 4000 lines of executable code. The parts that run in user mode are divided into small modules, well insulated from one another. For example, each device driver runs as a separate user-mode process so a bug in a driver (by far the biggest source of bugs in any operating system), cannot bring down the entire OS. In fact, most of the time when a driver crashes it is automatically replaced without requiring any user intervention, without requiring rebooting, and without affecting running programs. These features, the tiny amount of kernel code, and other aspects greatly enhance system reliability.

MINIX 3 is initially targeted at the following areas:
  • Applications where very high reliability is required
  • Single-chip, small-RAM, low-power, $100 laptops for Third-World children
  • Embedded systems (e.g., cameras, DVD recorders, cell phones)
  • Applications where the GPL is too restrictive (MINIX 3 uses a BSD-type license)
  • Education (e.g., operating systems courses at universities)


MINIX 3 Features

  • POSIX compliant
  • Networking with TCP/IP
  • Two ANSI C compilers (ACK and gcc)
  • Over 400 UNIX programs
  • Many improvements since V2
  • Full multiuser and multiprogramming
  • Support for memory up to 4 GB
  • Device drivers run as user processes
  • Full C source code supplied
  • Runs on 386, 486, Pentium, etc.
