According to Ubuntu official release note, Ubuntu 9.10 has changed the input method from SCIM to iBUS.
New input method framework
Ubuntu has switched to IBus as preferred input method framework. Unlike the previously used SCIM, IBus is under active development and fixes a number of SCIM’s design limitations.
The language selector tool now gives the user the possibility to select the preferred input method framework.
That was why I got the error message “no configuration file “scim-bridge” exists.” below when I tried to switch on SCIM package based on the old instruction.

I have never tried installing Ubuntu on the Microsoft Virtual PC before, I did successfully on VM ware though. If you don’t know what Ubuntu is, please Google it, basically it is a Linux operating system with pretty desktop features. In the Thanksgiving holiday, I used my DELL Dimension 4600i (Windows XP sp3) to explore this option which turned out a good experiment, even Microsoft officially says its Virtual PC does not support Ubuntu.
The following is what I used to install Ubuntu.
Virtual PC 2007, (get it here).
Ubuntu iso image, (get it here).

Today I was asked to come up a solution to a simple request: a co-worker needs to show a form screen to the customer on a secondary monitor after she completed the entries on her primary monitor; after the customer verifies the form fields, my co-worker should be able to move that screen back to the primary monitor.
It sounds easier, but the problem is that the secondary monitor and the primary monitor are sitting back to back. It is impossible for the co-worker to position her cursor on the secondary monitor to drag any windows back without seeing them.
Cloning the two monitors could work, but the co-worker does not want the customer to see every steps during her work afterwards.

Just gave up my favorite Blackberry Curve 8330 and upgraded to the new Tour 9630. With excitement of having a new gadget, I had to go through some tweaks, customizations to make sure my same device use experience as the old “toy”. Here write down some useful tips and links for the future reference.
First of first, I need to backup the data from the Curve 8330. Even I have BES (Blackberry Enterprise Services) on it, I still used cable and Blackberry Desktop Manager (version 5.0.1 see the link below for the downloading) to backup all to my desktop in case the BES did not sync everything last time.
Then I need to wipe clean everything from the old one since I do not want some one else to read my funny, private or business related emails. For how-to wipe data from Curve 8330, please refer my previous post.

Just helped a friend to upgrade her secondary DVD burner. And the installation was the easier part but made it recognize all medias was a harder one.
Since there was another Pioneer DVD burner in the machine already with Master jumper on the secondary IDE channel, I installed the new SONY one with Slaver jumper. After that, it can play any DVD disk (DVD+/-R, DVD+/-RW), but could not detect any blank DVD+/-R disks. Whenever any such disks were put within it, and you click the disk driver a “error access” message was prompt. Well, stranger enough the DVD+RW disk was OK though.

Recently I tried to boost up the performance for one of my Joomla powered web site. So I enabled the System Cache plug-in through Plug-in Manager which is a separate tool from the regular Cache setting in Global Configuration. What does this cache plug-in do? In one simple sentence, this plug-in creates page-level cache files which can serve to the afterwards visitors to reduce the burden of calling database each time.
At the first few days, everything was working fine with some kind of performance gains on this Joomla site. Even at some times it caused mirror inconveniences when I was updating the contents or modules. I had to delete the cached pages to see my new changes. But I was still happy.
Till last week, some of my other web sites started to act weird. I could not upload new pictures, some of web sites threw the 500 Server error (see the below of an example):
“Error 500 – Internal server error
An internal server error has occured!
Please try again later.

Just read the hacker quarterly magazine 2600 while I am in the SQL training. And I found out the information on the Page 19 is very interesting. Within it, the author taught how to generate the valid credit card numbers to fool some free trial web sites since these web site will not verify the credit card is real, but only to check these numbers are valid.
I think it will be a good point for us, as developer, to use these formula to do some simple credit card numbers validation as well in our code. Or just simply to generate some fake-real credit card to do the application testing.

I was thinking to update some of my ASP.net applications which are sending alerts to subscribers via emails. The update will allow them to send out alerts as SMS (Short Message System) or text messages to users’ mobile phones.
I believe we need some third-party add-ons in the ASP.NET code to accomplish the above. But in North America, there is a work-around to do so since most of the cellular providers have a email-like system for their phone numbers.

It has been a while since Microsoft’s new OS Windows 7 released on Oct. 22, and it got a lot of positive reviews from the beginning. As an IT guy who always likes new stuffs, I of course could not miss any opportunities to touch this new baby. From what I read and what I hands-on, overall I like the new OS a lot, especially the nice, sleek style, candy looking.
But do you need to upgrade your OS just for that? Or do you need to upgrade your operation system at all? Again, that depends. For me, I will not have any plan in the near future to upgrade Windows 7 on my home machine. Reasons are:
1), I just re-installed my home machine with Windows XP due to a crashed hard disk, so I really do not want to go into the same hassle again since you can not simple upgrade to Windows7 from Windows XP (but you can try PC Mover if you want);
