after a month i tried to use backtrack 5, i found out that my disk space allocated for backtrack 5 was nearly empty, 10 GB was too small. So i’d like to add new disk space, but i haven’t found the way to do it. I came up with uncool steps.
1. Remove old backtrack installation
2. Reinstall backtrack with new disk space allocation
to remove backtrack installation, which is dual booted with windows 7, i have to make sure my windows 7 can still work well. after googling, i got the message to do fixmbr to recover windows 7 boot manager. so here are the steps.
A. Fixing windows 7 boot manager
1. prepare your win7 installation disk (dvd/usb), plug it in.
2. start your computer, set the boot priority from bios setting (first boot usb, or cd/dvd room)
3. when windows 7 installation comes up, choose repair
4. choose repair this computer with recovery tool, click next
5. choose command prompt
6. enter this command
[php]bootRec.exe /fixmbr[/php]
7. reboot your computer
B. Remove backtrack
1. now your computer should start the win 7 automatically
2. go to control panel > System and Security > Administrative Tools > Computer Management > choose Disk Management (under storage properties)
3. u will see clearly your computer partitions, delete your backtrack partition by right click > delete Volume
4. after it is deleted you will have new disk space and u can expand your other windows partition.
that’s all
when i added new user in my ubuntu hosting and try to access the site, i got the message. i spent some time searching for the problem and solution. my first guess, there is problem with file permission in the home directory. read about unix/linux file permission on my site here.
i use this step to solve the problem. Continue reading You don’t have permission to access / on this server.
in unix/linux sistem it is easy for us to define directory or file permission. there are 3 options : read, write, execute. these options are represented with binary number rwx, respectively for read, write, execute. there are also 3 user type/level exist : user, group, other. user means the specific user logged in the system which is also the owner of the file / directory, group mean several user that has been defined on one group name, and other represent any user exist or the whole world.
each file/directory in unix/linux will be labeled by specific permission, such as drwxrwxrwx. Continue reading File Permission on UNIX/Linux
After i use wordpress plugin for mobile web application “WordPress Mobile Pack” i found that it caused duplicate meta description. Each of my link/permalink will be appended “?wpmp_switcher=desktop”, which indicates that instead of using the web mode display, we will use desktop mode display.
since it created miss configuration to meta description tag, i prefer to remove the plugin. but the affected links seem still the same. trying to understand this thing, i did these 2 things.
1. Clear the dns cache and browser history just to make sure these aren’t the thing that causes the problem.
2. Deleting completely any “WordPress Mobile Pack” in folder wp-include>>themes.
It seems working on my website, u can try to do it with yours too. hope this helpful for you.

Some of the problems sometimes arise with Mysql database and WordPress. One problem that sometimes arises is the web displays the error Establish a database connection, this problem usually occurs because we haven’t started yet our mysql-server program, or already started but not run well. The solution is simply to check whether or not our mysql running and try to run it.

service mysql start
