New Mainframes from Sun and Fujitsu
Sun in collaboration with Fujitsu has launched a line of SPARC/Solaris machines targeting very high scale computing environments.
The machines are general purpose, run Solaris without modification, but offer features and scale that were historically the stuff only mainframe customers could love (because no other computers offered them).
The new line will be called M-class, M for Mainframe - says Jonathan Schwartz from Sun.
According to Sun’s official announcement from their website key features are:
- Up to 64 dual core SPARC64 VI processors
- The Sun SPARC Enterprise M9000 can be expanded from 32 CPUs to 64 CPUs by adding an expansion cabinet
- Up to 24 dynamic domains
- Up to 2 TB of memory and 288 PCIe or PCI-X slots with the optional External I/O Expansion Unit
- Thousands of Solaris Containers per system
This monster will cost you from $511,385 (US) and onwards depending on your configuration.
I believe Sun is directly competing with IBM’s P Series and HP’s Integrity Servers.

Linux Desktop for old PCs
Continuing my post on how to use old PCs this post is about how you can use your old PC as a spare Desktop. You can use it for listening music, do some text processing and surf the internet.
In my case I chose a Dell box with Pentium II, 399Mhz CPU, 64MB RAM and 4GB HDD. I am quite sure you can find one of these at home or at your working place just lying idle.

my new phone
Yes I am a happy owner of a new phone pda phone - HP iPAQ rw6828

- Better music/media player
If you are a PDA phone user please do share your experiences and softwares used.
Do and Don’ts in setting up WiFi Access Point
Sometimes I can see my neighbours use WiFi Access Points with no encryption at all. This is very dangerous! Not only will they have access to your home network, but they can also misuse the internet connection if you have one. So I came up with a very basic check lists of what you should and should not do:
- When you setup you WiFi device, ensure that all the default informations have been changed. Like password and admin username if possible.
- If you can restrict WiFi access by MAC addresses would be an extra precaution.
- Encrypt your WiFi connection with at least WEP encryption. If you use WEP then use 128bit key.
- If you can try to use WPA encryption. It is said to be more secure then WEP.
- Put your WiFi Access Point away from kids, TV or power cables. It is a good idea to mount it to the wall or something.
- If your ADSL modem is not built-in the WiFi router then try to keep them together. Neatly arranging the cables between them.
