I have a bad news. Due to the limited time I have, the project was drop as my initial plan. But something was change; I was planning to make a UI-less utility to make it simpler to develop. I don't need to care the about UI design issues, the feel and look. This project will be changing its development tools from MFC to STL. I was planning to make it executable in both window and Linux OS since I am switch my development environment to Linux.
Currently I was busy in setting up my Linux box on my machine. I have facing some troubleshooting issues during setup. (I am newbie in Linux.) Not the installation of Linux but the driver itself. It is pretty hard to find a driver in Linux. But I enjoy the process.

WHAT is Winmodem
WHAT is Winmodem
These few days working on Linux modem and been struggling in installing the driver. Winmodem and Linmodem are a new term which I see frequently during my searching process. I was curious about these and did a search from the Internet. This is what I got.
Another resource which talks more on this is available from this link.

"A Winmodem is a software modem designed to work with the Microsoft Windows
operating system. A traditional modem uses hardware to perform its tasks, but
Winmodems perform their key tasks with software. This makes them smaller and
cheaper to produce, but it also means they cannot be easily used on other
operating systems because the driver support requires far more effort to
produce." - en.wikipedia.org/wiki/Winmodem

Disable XGL on MANDRIVA 2007
Well! I got the NVIDIA ready on my PC now. I have two options to turn into 3D mode. One is AIGLX and the other is XGL. What was that actually? Have a quick search at Google, but I still couldn’t find one solution.
First I try on AIGLX; this seems no different with the previous setting which is using the generic driver. Then I try on XGL, the whole desktop was turn into white screen with a black box at the middle (I think that must be the splash screen). I am still able to see the splash box at the initial stage of the loading process just before the window manager was loaded. I still can hear the startup sound but I get a white screen after the window manager was loaded.
Did some search on the forum found out that using XGL on NVIDIA is still buggies. Some will say need to do some hacking stuff. I spent around one week to figure out the way to disable XGL in console.
Here is how I did it. Boot in failsafe mode. Change to root user. The reason for this is to let the ls command to show files in color mode. I have tried this without login in as root user. The ls command doesn’t show files in color mode. Go to the directory etc/sysconfig to look for xgl file. Edit it by using vi command. You will see just one line in that file. Xgl=yes. Change this to Xgl=no. Save and reboot again.
I have found a very good resource for vi command. You can get it from here.

Install NVIDIA on Mandriva 2007
I have installed the display card driver on Mandriva 2007 successfully. Cheers!! There was a long story in order to get the work done and due to the lack of knowledge in Linux, I have been hitting the wall for so many times. You know what; I have spent up to three days to install this driver. This is so ridiculous.
First day:
I get the driver from NVIDIA website. There was a file with RUN extension. I think this must be EXE file for the setup. Unfortunately I am not able to execute this file under my user account. Why? In order to execute this file I must have the administrator privilege.
How can I gain the administrator privilege? I think that must be the root user. But how can I switch to root user?
I spent a few hours to search in my Linux book. Frankly, I have learned this shell command during my school time. I have totally forgotten my learning due to the reason of I never use Linux in my daily work as it can not play my favorite games. I just learn for fun. By the way the driver is quite hard to find too.
Second day:
I continue my searching. Finally I found it. It is su command. But I get this from Internet, not from the book.
Although I have successfully switch to root user but I am still not able to execute the program. This is because it require me to log out from X window then only I can continue the installation.
Well. This seems a bit tricky for me as the distribution which install on my machine is automatically start X window after boot up. I have no clue on how to exit the X window. As I mention earlier I have totally forgotten what I have learn.
I did a search on the help to look up how can I logout to the console mode. Frankly I had never trying to logout to Linux console on this distribution since the installation. I have spent few hours on this issue. Fortunately I have find out how to do that.
Now what? This is the real time for me to install the driver at the initial though. It failed again during the installation process; an error showing that the driver is not able to find the source tree.
What the source tree exactly is? I spent some time on Internet to dig out this.
Luckily this is not a big issue. It is actually referring to the kernel source tree. Wow, this really a bit surprise for me. This is my first installation experience that requires the source tree to compile the driver. I had never done it on Windows. This is so interesting...
Third day:
The source tree needs to be installed manually in my machine. It is not in the default list of the installation. This can be done under the control center.
Well. Everything is ready. Guess what? After the installation, first thing I am going to do is to turn on the 3D mode. But I don’t see any 3D after the configuration. I do log out and back again in order for the new setting to take effect. Does the installation completely done? Do I need to make some configuration to the X config file? One thing for sure is the desktop alignment was correct (before this the desktop alignment is shift at the right side) and during the boot up process I can see the NVIDIA logo shown up.
Does this means that I have successfully install the driver?

Setup wireless network in my uncle house
On Wednesday, my uncle called me to help him to setup a wireless network. Unfortunately I don’t have this knowledge and I do tell him that I don’t know how to do that. But he keep persuading me to go as it is very easy to setup. But in fact it is not. The first thing I ask to myself is how am I going to connect my PC to the wireless router? There must be some setting for the IP address. But how am I going to do that? I spent a few hours there try and error. Base on the experience (just two months) that I have when I work as an IT support in past few years ago. I try my best to do it but it still wouldn’t work.
At last I sitting there look at the computer. How am I going to communicate with router from my PC? I do looking to the manual but it still wouldn’t work. I call for help rather than just sitting there searching my past experience regarding to wireless thing. Frankly, I have zero experience on wireless and little knowledge on networking like setting up a print server. That’s all. The person I call is the salesman where the wireless device is purchase from. He don’t seems really want to help me because he keep pointing out that he is a distributor and they don’t provide guidance support. Because I don’t have knowledge in wireless thing, even I am not able to find out which network I am connecting to. He feels that I am annoying. Then I let my uncle handle him and my uncle successfully persuades him to provide guidance to me.
At first he teaches me on how to setup the wireless security, and then he teaches me on how to connect to the wireless router and setup some configuration setting on the router. Due to some error during the setup, I need to restart my setup again. Thus the security setup was gone. I repeat the same steps again. Finally I have the wireless router working probably. And now I want to setup the security on the router. The salesman seem little busy and I feel that I have bother him for so long, thus we drop the line. I follow the steps that he teaches me few minutes ago.
Oh no! Something goes wrong. The Internet connection was down. I am not able to connect to the port. What was happened? Then I remove the password security. See whether this is cause by the security issue? It still wouldn’t work. No matter how hard I have tried, it still wouldn’t work.
On my way heading home, I feel that I am not a perfect IT guy. To survive in IT, I must take initiative to learn new thing. But somehow although learn the new thing but I don’t have a chances to show off my skill on my work as my work don’t need it, it were still useless.

Tedious Defect
Monday (16 July 2007)
This is a hard war. I am working on a defect which is having calculation error in report. At first I suspect there is a double entry error. This could be a new challenge on me as I never work this before. I am spending the whole day to look for the real problem in the source code, resource file and the work flow. Unfortunately all the effort are wasted in this day because nothing can be found.
Tuesday (17 July 2007)
There was no error in double entry because the calculation was a real time process during the "report making" process.
Today I dive into the code to see how double entry was created, how the journal entry is made and how the recap function work. Actually the error is not here. If this is an error, there must be an error in double entry. Since double entry is working fine. There must something wrong in other place. I stop my analysis work on double entry and request help from my senior. After the discussion, I suspect there must be some work need to be done in resource file.
Wednesday (18 July 2007)
I have found something in the resource file. This is very tricky. Every ID defines in resource file represent fields in the data file. This field may have some attribute apply on it to indicate how the field is 'work'. A few changes were made and it works finally. But I need to test other part of the report to ensure my work is complete.
Thursday (19 July 2007)
I am doing the wrong thing. All my works are gone. My effort was wasted. I am not yet clearly understand the real problem. I am not yet clearly understood the work flow. I though I have complete my work. But the fixed I have done will be reactivated in someday. I have no clue how this thing should be fix.
Friday (20 July 2007)
YES!! I have completed the fix. The report is showing the correct value in both invoice and purchase. I couldn't sleep well on yesterday night just because of thinking a 'real' solution for this problem. Now it is working fine here.
Anyhow I found an error during the crash test. I am almost complete my work. At this moment I need to calm down to check every test detail. It should be done in one day effort.

New Explore: MCNLive
On last weekend, I found a mini OS called MCNLive. MCNLive is base on the Mandriva 2007. It just cost me around 440MB and without the need to installed it into hard disk. Everything are load from the CD and execute from RAM when it is needed. Thus I did a test on it. I burn it into CD, and boot up from the CD with my PC which have Windows XP installed.
When it first boot, I see a series of boot option. The first boot option is default option. (I like this option.) Choose on it, wait for a few second and it is ready to be use. One thing I notice that the CD ROM was locked. When U load an application, I saw the CD ROM is spinning. I'll never eject the CD until I shutdown the OS.
I have try on other boot option like "some thing called boot from NTFS hard disk", I don't really remember the full name. With this option, I can eject the CD after the OS is bootup. This is the most interesting part. The other is called "boot from USB". I get stuck the middle during the boot process. I don really know what happen. May be I don have a USB ready during that moment.
At last, I can have an option to remaster the OS. This is really interesting. When I found something is not install in the OS. I can install it and remaster the CD. Something like customization. This is so great. But the OS size might increase depends on the application installed. I never try on this. Will make it one day.
