KVM and Virtualbox rants
Redhat 6 used KVM(?) in virtualization but Rhel6 DVD doesnt have kvm rpms. You can't rum KVM on a virtualized environment in Virtualbox. Virtualized processor doesnt support hardware virtualization(VT-x and AMD-v). On that note, i might need new computer just to simulate KVM that i cant afford as of now..

Oracle Certified Sytem Admin for Solaris 10
Passing score:63
Your Score : 70
Result: PASS
Whoa i barely passed Oracle Certified System Admin for Solaris 10 (310-202) Part 2 exam. Caught off guard on LDAP and I just hate Jumpstart questions. Already convinced myself that i failed the exam because of the low percentile per topic, but what a relief when the examiner handed me the test printout with the word PASS.
Have to relax first this weekend before i go back to my labs.. hopefully RHCE eh :)

New AVG Internet Security 2011 update cause Windows 7 to crash
I just came from my night shift and found AVG was updated and needed for a computer reboot. To my amaze, the New AVG Internet Security 2011 update causes Windows 7 to crash. Even in Safe Mode, it wont boot at all. As of now, AVG haven't release a quick fix yet. Or in worst case scenario, reinstall Windows.
====
Update
How to fix your computer after AVG Internet Security 2011 update windows crash
1. download and burn AVG Rescue CD http://www.avg.com/ww-en/download-file-cd-arl-iso
2. Boot thru AVG rescue CD. Go to Utilities > File Manager then navigate to /mnt/sda(x) where x depends on the partition of your computer.
3. Rename the following files
\Program Files(x86)\AVG\AVG10\avgrs*.exe >> avgrs*.exe.bak
\Program Files(x86)\AVG\AVG10\avgchsv*.exe >> avgchsv*.exe.bak

Trendmico doesnt want you to buy other Antivirus software
I'm using Trendmicro Internet Security Pro for almost one year and my license will expire Jan 2011. Since it will be SITEX this coming weekend, its time for me to hunt and try other antivirus system. First choice is Kaspersky. When im trying to check the pricing online, i was amazed that Kaspersky's online store was tagged as Dangerous by Trendmicro's Web filter. Now thats what i call "killing the competition" :)
But i wont settle with Kaspersky as the review is not that quite good. Will try AVG or Nod32 or avast. Lets see..

Sony Ericsson Xperia X10 Unboxing
This is not unboxing post anyway since this is an overdue entry on my blog. Quite busy with work eh. Sony Ericsson Xperia X10, my 4month-old smartphone. The flagship of Sony in the Android-phone arena. At first im kinda angry with this phone because the battery life would not last for 24 hours of normal usage with no mp3's sound trip and movie. But since SE released the updated firmware version R2BA020, battery-life goes with 3 days of normal usage. Not bad for a smartphone if you ask me. Can't wait for the next update due Q4 of this year.
Package includes free pouch, phone, and headphone
Back of the phone






This is the old Firmware, new update is available now in Singapore and Australia thru SEUS (Sony Ericsson Update Service)

Bazooka Joe
[caption id="" align="alignleft" width="170" caption="Bazooka Joe"][/caption]
How i miss Bazooka Joe. Kung ikaw ay kabataan ng 80's at early 90's, malamang kilala mo si Bazooka Joe. Ito yung bubble gum na may free comics ng mga misadventures ni Bazooka and the gang. Nangungulekta ako nito, pero sa kadahilanang nakabalot sa bubble gum ang comics, madalas itong pagpyestahan ng mga langgam sa aking taguan.
May bago ng henerasyon ng Bazooka, pero wala pa akong nakikita dito sa Singapore o kaya sa Pinas na nagtitinda nito.. Sana maging available na ulit ito sa suking tindahan natin para maipakita ko ito sa magiging anak ko at para maikuwento ko na kay Bazooka ako natutong magblow.... ng bubble....
