Apricot 2007

Apricot is Asia Pacific Regional Internet Conference on Operational Technologies event. This annual event now being held in Bali, Indonesia. You can read the program of Apricot 2007 on http://www.apricot207.net. It's the first time for Indonesia become Apricot host. Apricot is important event for not only for network engineer in ISPs or companies but also for Internet community in Asia-Pacific. It's become place to study new Internet technology and new Internet operation directly from the expert. Many tutorial and workshop sessions in Apricot, such as IPv6 (Internet Protocol version 6), DNS, Internet routing, VoIP (Voice over IP) and Network security. Everyone can choose the tutorial and workshop on their interest.
From my experience when I was on Apricot 2004 at Kuala Lumpur Malaysia, this event is very usefull, beside getting new knowledge you can also get contact persons from other regions. So you can expand your business and skill to other regions.

Minix 3

I read about Minix 3 on ;login February 2007 volume 32 number 1.
As you know it wrote by Prof Andrew Tanenbaum with his colleagues and his students.
The title: Roadmap to a failure-resilent operating system.
Here's I rewrite the abstract:
-----------------------------------------
In recent years, dependability and security have become prime concerns for computer users. nervertheless, commodity operating systems, such as Windows and Linux, fail to deliver a dependable and secure computing platform. The lack of proper fault isolation in the monolithic kernel of commodity systems means that a local failure can easily spread and corrupt other components. A single bug, say, a buffer overrun in a network driver, can overwrite crucial data structures, causing a subsequent, but unrelated, action to trigger a fatal exception. Recovery is usually not possible except by rebooting the computer.
--------------------------------------------

In this article Prof Andrew Tanenbaum, describe about Minix 3 operating system development and tentative roadmap for future work.
I rewrire The author's statement to achieve fault resilent:
--------------------------------------------
The key principles we used to make Minix 3 failure resilent are fault isolation, defect detection, and run time recovery. Fault isolation is required to prevent problems from spreading and limit the damage bugs can do. When a bug is properly caged it becomes easier to pinpoint the defect, and rocovery may be possible. In the following we briefly discuess how we realized each principles in Minix 3.
