Just some long over due update.... I have upgraded to Kubuntu Jaunty 9.04 This time, they have finally got it rt73usb wireless drivers right. I have disabled my own complied driver before upgrade. Now I am using default driver. I have been using it for a few weeks and so far no connection dropping and download speed is good. One little surprise after upgrade was that my display was corrupted when it enters KDM, I can't even go to console mode with Ctrl-Alt-F1. I had to SSH into my machine from another computer and type: aticonfig --initial This configures a default set of display settings into my xorg.conf. After this, everything is working great. The only slight disappointment is that lm-sensors module for my phenom processor is still not available. I can only monitor using mobo sensors. Perhaps I'll try to compile my own module when I have some time later. Now I am just too busy at work and also all the wedding preparation.. sigh..

Recently, my wireless connection seems unreliable. It keeps dropping from time to time unpredictably. I cannot just reconnect it with network-manager. I had to unplug my Linksys WUSB54GC usb stick and plug it again to work. After getting frustrated with this, I finally did a quick google search and found out that this is somewhat a know issue with as describe in https://bugs.launchpad.net/ubuntu/+bug/283759 The suggested solution is to install linux-backports-modules-generic package. I am trying it out now and I'll update this later if it works out well. UPDATE: Nope, not working for my current intrepid kernel: $ uname -rv 2.6.27-9-generic #1 SMP Thu Nov 20 22:15:32 UTC 2008 The kernel module won't even load due to some "unknown symbols" error in the syslog Next, I have also tried compiling the compat-wireless from http://linuxwireless.org/en/users/Download but also could not work. This time, the kernel modules could load, but could not connect at all due due to time...

Recently I have upgrade my machine to a Phenom 9650 with 4GB RAM. So I decided to use install Kubuntu 64-bit. However, I had to install the 32-bit libraries and nspluginwrapper for Adobe Flash Player to work as it previously only 32-bit binaries was release. Now, Adobe has released an Alpha "refresh" version of native 64-bit Flash Player to enable pure 64-bit web surfing experience! To install, first uninstall currently installed flashplayer with the following commands: sudo apt-get purge flashplayer-nonfree nswrapperplugin Then download Flash Player 10 for Linux 64-bit from here . and extract libflashplayer.so to the following directories: ~/.mozilla/plugins/ /usr/lib/firefox/plugins/ /usr/lib/mozilla/plugins/ Restart firefox and go to your favourite flash site. For me, youtube.com and various flash site works well! The only problem is that konqueror doesn't seems to like it and does not display properly and it has been reported as bug 169626 .

Recently discovered that I could enable nested paging for Virtualbox 2.1. Nested paging is a new hardware virtualization extension on AMD K10 Barcelona/Phenom and Intel Core i7 Nehalem processors that allows processor to offload memory paging required by the guest OS that is traditionally done by the VM with shadow paging. Since it is a new feature, it is not available in the configuration UI yet. First, you will have to enable hardware virtualization (VT-x/AMD-V) in Settings -> Advanced. Then, nested paging can be enabled as described in the VirtualBox User Manual with the following command: VBoxManage modifyvm -nestedpaging on The performance boost is quite noticeable. The boot up time for my virtual Windows XP has drop from about 25 seconds to 18 seconds. Super PI Mod has dropped from 39.159s to 36.016s Various benchmarks on the net show performance boost up to 30%. I'll run more benchmarks next time.

I was curious to figure out what is the carbon footprint of my car and a 500km journey. A bit of googling, I figure out from US EPA that 1 US gallon of gasoline produces about 8.788 kg of CO 2 or 2.321544 kg of CO 2 per litre . My car's mileage is about 0.065 litres/km or 15.4 km/litre. So, for a 500km journey from Melaka to Penang should consume about: 500 km x 0.065 l/km = 32.5 litres of petrol. So, the CO 2 released for burning 32.5 litres of petrol: 32.5 litres x 2.3215 kg/l = 75.45 kg of CO 2 Finally for my journey from Penang - Malacca - Penang: 2 x 75.45 = 150.90 kg of CO 2 for this weekend holiday trip. Bad bad boy... Anyway, Happy Diwali to my Indian... :-)

Ok, make a guess. Which of the two following DIMMs are fake. Now, recently, I bought a Corsair Ultra Performance XMS 512MB DDR400 RAM from lelong.com.my (a local ebay clone) because I already have an existing Corsair RAM and getting another one should give my aging machine a performance boost with more memory and faster dual channel memory bandwidth. I was pretty excited when I receive the parcel a few days ago. I plugged it into the mainboard and it seems to work. It passes the memtest86+. However, I notice something fishy when the memory speed shows 333MHz when it should be 400MHz. I booted into the old rusty WinXP (linux lshw does seems to show much useful info), and I ran PC Wizard . The following is part of the report from PC Wizard. >> Information EEPROM (DIMM1) Manufacturer : Unspecified Part Number : CMX512-3200C2 >> Serial Number Type : DDR-SDRAM PC3200 (200 MHz) Size : 512 Mb (2 rows, 4 banks) Module Buffered : No Module Registered : No Width : 64 bits Er...

Just installed updated to KDE 4.1.1 from Kubuntu Member's KDE4 PPA. The server seems rather slow. It took me quite a few nights to download all the over 70 packages. I wonder if there are any Asian mirrors for the Launchpad PPA. Anyway, here's my desktop screen capture.
