Busy day 2

Huh? I can't install Oracle free edition in lab? Yeah it's true coz it will break the policy. Now I understand. Dr. Janet instructed me not to do it. But the student can install it at home. She wanted to discuss this issue further with her colleagues back in Australia on how to get Oracle free or with discounted price for educational institution. She said that Oracle Malaysia is nasty. huh?

Day 2 meeting revolved around various subjects will be taught and softwares required. I was surprised to hear that for Computer Graphics subject, Java Swing Package will be used throughout the course. Students are expected to develop Computer Graphics applications with it. I have learned it for quite some time and it is quite difficult. They have to remember many Swing APIs and the RAM should be higher than 256 MB to run it smoothly as Java programs will chew up your memory in an instant.

A busy day for a lazy man

Today is so full of meeting from nine to 5. meeting packed day. I have a meeting with Flinders University regarding courses ShahPutra want to offered here. They have strict requirements regarding students intake, softwares and technology that we have here. "We are very Java" - said Dr. Janet, the IT Head The course will be offered is Bac. Of Comp. Sc And IT. I, as an system administrator should provide them with softwares required to run the program such as Java, C/C++, A web server (Apache), JDK 1.4, J2EE, Linux OS, Oracle and also MySQL. Thank god I can download the free edition of Oracle on Oracle website. That will save cost as our boss like. Students can run Oracle server on their own PCs and do their work.

Last night I read the RAID manual for the 10th times. I realized that for RAID 5, I should make RAID 1 first and booting can be done from it. I have three disks that I could make RAID 5. It is no automatic process for this as many installers do not support configuring…

Williams F1 gives green light to Linux

HP Linux supercomputer aids aerodynamics modelling for team cars
Peter Williams, vnunet.com 02 Oct 2003

The BMW Williams Formula 1 (F1) team has dramatically improved its high-resolution aerodynamic modelling of team cars by introducing an HP Linux supercomputer cluster.

The company, which currently lies second in this year's F1 Constructors' Championship, has added "several hundred" HP ProLiant Intel-based servers to its Oxfordshire headquarters.

Apart from driver skill, competitive advantage can be achieved through tyres, engine power, chassis and aerodynamics, with the latter the most difficult to control.

"Last year showed us that our chassis was a model of reliability but that there's still room for improvement, particularly on the aerodynamic front," said Patrick Head, technical director at Williams.

"[This] has given us the necessary technological leadership and expertise to design the revolutionary FW25 [this year's F1 car] rather than a modi…

Linux revs up Renault F1 testing

Linux revs up Renault F1 testing

IBM e1350 Linux cluster cuts simulation time from three weeks to 18 hours
Robert Jaques, vnunet.com 15 Mar 2005

Linux has helped the Renault Formula 1 team to slash its engine and chassis computational analysis time by 90 per cent.

The team dramatically cut the time it spends performing computational analysis, and ultimately reduced development costs, by deploying an IBM e1350 cluster running Linux. The system is based on IBM eServer e325 and e326 servers with AMD Opteron processors.

In addition, Renault Formula 1 has deployed two IBM eServer pSeries 630s running AIX, and one TotalStorage DS 4300 storage server, to capture and store the computational data generated by the e1350 cluster.

Christophe Verdier, Renault F1 Team IT director, said: "The performance of this system has enabled Renault F1 to fully optimise its V10 engine capability. This has given the team a considerable advantage, since a race is as much won in the factory as it is on the track.

Firefox Browser Adoption Rates Slow

Open-source Web browser Firefox is continuing its spread across Europe, although the pace of adoption has slowed somewhat, according to a recently released report. French Web metrics company XiTi noted that Firefox now accounts for about 14 percent of browsers in Europe, up from 13 percent in April and 11 percent in March. The numbers fall in line with U.S. usage, which is approximately 13 percent. Finland shows the largest Firefox use, with over 30 percent of Web users employing the browser. The country is followed by Germany, with over 24 percent, and Hungary, with about 22 percent. At the bottom of the adoption list were Luxembourg, with 10 percent, Lithuania, at 7 percent, and Monaco, with 6 percent.

Slow Down
Mirroring a trend seen in the U.S., Europe's Firefox adoption rate appears to be slowing. Analysts point to several possible factors for the trend, including recent security flaws involving cross-site scripting and remote system access vulnerabilities. The flaws were rated…

RAID - Revisited

I'm still researching about RAID. I have done software RAID before and am looking for some hints on hardware RAID and the advantageous over software-based RAID. Let's get some basic picture of RAID and beyond.

What does RAID stands for ?
In 1987, Patterson, Gibson and Katz at the University of California Berkeley, published a paper entitled "A Case for Redundant Arrays of Inexpensive Disks (RAID)" . This paper described various types of disk arrays, referred to by the acronym RAID. The basic idea of RAID was to combine multiple small, inexpensive disk drives into an array of disk drives which yields performance exceeding that of a Single Large Expensive Drive (SLED). Additionally, this array of drives appears to the computer as a single logical storage unit or drive.

The Mean Time Between Failure (MTBF) of the array will be equal to the MTBF of an individual drive, divided by the number of drives in the array. Because of this, the MTBF of an array of drives would be to…

RSS

If you are lazy to update your website, there's an alternative to it. It is called RSS feeder. With it, you have no need to update your website with latest news from other sites. If the sites provide RSS, you can feed your website with their news with RSS feeder and it's done automatically. But before that, you should know how to setup one. There are many RSS feeders in the market and I personally use MagPieRSS.

Add RSS feeds to your Web site using MagpieRSS
Syndication of material from other sites is a good way to get fresh content on your site. As visitors arrive at your site they can see a teaser for the syndicated content and a link to the publisher. If they are interested in an item they can follow the link to the original location. You can add syndicated content to your site using the Really Simple Syndication (RSS) protocol and a bit of PHP code in the form of an application called MagpieRSS. Here's how.

MagpieRSS is an RSS parser written in PHP. It supports RSS 0.9 a…

Do your softwares suit your business or are you trying to fit your business to your softwares?

When I was reading Linux Format magazine yesterday, I came across this statement of an advertisement. This mag is hard to find in Kuantan (only at a bookshop in MegaMall which I think I'm the only one who buy it :) ). Other mags I have on my bookshelf is Linux Users And Developers and Linux Magazine which my friend sent me from London. Thanks Mark.

It's good to read Linux mags every night before going to bed. You will fall asleep when you start reading it. :-)
