The concern for performance in time sensitive financial environments is very real when the London Stock Exchange (LSE) had a system fault in Sept 2008. The TradElect system in place was MS Windows based and may be considered to be replaced as interviewed by Computerweekly and finextra.com.
During the recent visit by Redhat to Malaysia, the New York Stock Exchange (NYSE) was mentioned as an example of financial systems using Linux. The trading speed of 0.4 milliseconds have been mentioned in the same article. This is almost double the speed of the TradElect but will the investment of billion of Pounds justify replacing it with another new system like Linux? Anyone knows what KLSE is using?
Financial systems world wide looking at the future of their architecture might learn a lesson or two with how the LSE takes charge of their investment and business needs.

[kubuntu] Rename FAT label
The Kubuntu Jaunty did not allow me to change the USB diskdrive label. This I found was because it is FAT32 formated. Why would I want to change the label and maintain it as FAT32 format?
Step 1: Install mtools if not already done.
$ sudo apt-get install mtools
Step 2: Identify the USB diskdrive (or partition) to be formatted.
Plug in the USB diskdrive. Then identify the USB device in a terminal, type:
$ tail /var/log.messages
I found mine as /dev/sdb1
Step 3: Rename the label with 11 characters maximum
$ sudo mlabel -i /dev/sdb1 ::0161234567
Test the results by unplugging the device, then plug back in to see the difference. Thank to the reference at Ubuntu.com website.
- If someone finds my disk and would care to return it, they can mount it and find my phone num ber as the label.
- The FAT32 allows me to plug the USB diskdrive to MS Windows and Linux operating system interchangeably.
- I backup to this disk for both operating system.
