Today, I read the newspaper, and found that there were a lot of people discussing this questions. You can read it from Yahoo! Answer. And there are a lot of people answering this expression equal to 9:

6/2(1+2) = 9

I really don’t understand the possibility of answering it as 9. Some of them said based on PEMDAS, it must be 9; also other said based on distributive property, it is 1.

Looking at the OpenOffice Impress default templates, they are too dull for me. Then, I am looking for the better template, but cannot find a better one. The main problem is the background. So, I decide to create my own template. I am using the background from deviantART user, PL0. Thanks to his design. Then using the GIMP, to edit the image, then make it as the OpenOffice Impress template. Have a look.

This is not an easy work for me.

1. Firstly, I download the Ubuntu 10.10 alternative CD ISO.
2. Then, following upgrade using the shell script by following this article.
3. Restart

No wireless device detected, cannot connect internet through WiFi. What the X?! I used this method before by upgrading from 9.10 to 10.4, but this time fail.

1. Then use the broadband connect to the internet
2. System > Administration > Additional Drivers
3. Download and update certain things, I don’t know what are they
4. Found “Broadcom STA wireless driver”
5. Activate
6. Failed! Ask me to check /var/log/jockey.log

Then I think I need to update everything, so I run System > Administration > Update Manager. Then I asked for “Partial Upgrade”, and needs to download about 200Mb data. Not the good solution. Search solution online. Then I found this.

My laptop has a built-in webcam. I was doing video capturing using webcam. Suddenly, the webcam could not function. Then I tried to restart, hopefully fix the problem. After restart, there was a taskbar notification mention that there is an unrecognized malfunction USB device. (I am using Windows 7)

So, how to solve this problem? This was not a driver problem. And I thought that maybe the webcam was broken or some hardware problem.

I was using Huawei E220, a very old USB Modem. Yet, running on Ubuntu does not have any problem.

Then I tried the new Huawei E1552 on Windows. Nicer interface. Newer is better. But when I tried it on Ubuntu, yes, Huawei Mobile Partner icon is on the desktop. Can open it. But I cannot connect to internet.

So, in order to solve this problem, I tried to search from Internet. Right, I need USB_ModeSwitch to solve this problem. Reading the page, you will find a lot of steps need to follow.

Finally, I wrote a Greasemonkey script. The script is target on a Chinese comic website. You can download the script here. I wrote the script because the links are not named in sequence. To offline read the comic, I would like to download the comic first. Then I can read the comic offline. After that, I can delete the comic.

But the name are not in sequence, I cannot download the comic using batch downloading. Thus, writing this script to produce the link, then from the link, I can download the comic with any download manager.

I need to add some text to a lot of text files. Previously, I used jEdit to perform regular expression for several files. But currently, I need to add the text for about 120 files. In order to do this, I tried using Unix tools, “sed”, “grep”, and “xargs”.

Firstly, I tried MSYS, yet it fails. Because the “sed” version was too old. Then, I used Cygwin.

My problem was to add the following text to the text files:

I found the following message when I was trying to install CVS on Ubuntu 10.04 with synaptic,

Please insert the disk labeled: Ubuntu 10.04 LTS _Lucid Lynx_ - Release i386 (20100427.1) in drive /cdrom/

I am not sure why is this message appears. But my Ubuntu 10.04 was upgraded from Ubuntu 9.10 with the alternative CD. Fortunately, I got the CD image. Thus, to solve this problem, I mount the alternative CD to the “/cdrom/” drive. Then, there is no problem for the installation.

Huawei Mobile Broadband, which I bought about 2 years ago, is failed to run properly on my HP Mini 1000 series with Ubuntu 10.04. It will keep trying to connect to internet, yet failed. And I also found a “MOBILE_CONNECT” icon on the desktop. If I tried to click it, it will immediately missing.

So, to solve this problem,

1. I right-click the NetworkManager Applet,
2. Edit Connections…
3. Goto Mobile Broadband tab
4. Click Add button
5. Then it will show the Huawei broadband device
6. Continue the steps for my service provider, which is Celcom
7. Can connect to internet properly.

I do this whenever I cannot connect to internet properly using the Huawei Mobile Broadband.

I tried to install Flash in Ubuntu. But there is a problem when installing “flashplugin-installer”. I cannot finish download the installation file from Ubuntu server. So, I tried alternative way to install Flash plugin.

I go to Adobe website, and download the Debian package. Then
sudo dpkg –install [filename].deb

Right, now can view Flash in web browser.
