Stupid default setting in SQL Server 2008...

I've created a table in SQL server 2008, then decided to change one of the column size from varchar(10) to varchar(50). When I try to save the changes I'm getting the error below:

"Saving changes is not permitted. The changes you have made require the following tables to be dropped and re-created. You have either made changes to a table that can't be re-created or enabled the option Prevent saving changes that require the table to be re-created."

In Management Studio, go to Tools -> Options then go to the Designer Page and uncheck "Prevent saving changes that require table re-creation".

Installing latest ATI display driver on Ubuntu...

Before start, please uninstall the previous version driver if there's any because the installer doesn't have the capability to auto uninstall. Otherwise proceed to installation step.

To uninstall, open terminal and run this command:
$ cd /usr/share/ati
    $ sudo sh ./fglrx-uninstall.sh
Then restart your machine.

To install, open terminal, go to the installer location and run this command:
$ sudo sh ./ati-driver-installer-.run
Follow the instruction. Once completed run this command:
$ sudo /usr/bin/aticonfig --initial
Restart your machine.

I did the installation process in "recovery mode". That's the only way the correct driver will get install. Otherwise it'll use the previous existing driver (sucks!!!).

Honestly, I hate ATI graphic card. The only reason I'm using it is because I urgently need a laptop and Dell doesn't have an option other than Mobility Radeon HD 4xxx series for it Studio XPS product line.

It's a shame that my ATI card with 1 GB memory can't even get the effects below to work but my NVidia 7600 GS with 256 MB memory perfectly can. ATI driver for Linux really sucks!!!!

1) Win 7 virtual machine on VMWare Player with Accelerate 3D graphics option on, is not working in fullscreen mode
2) Compiz Blur effect not working
3) Compiz Water effect not working
4) Compiz Fire effect not working

Update (28/03/2011)
I've been using CCC version 10.10 with driver packaging version 8.783 on Linux Mint 10 64-bit. So far it's the best driver. All the effect mentioned above working as expected (especially Gaussian blur). For VMWare machine with Aero effect to work on fullscreen, need to disable Compiz.

Update (11/10/2011)
For 64-bit installer to work, you must install the 32-bit library (ia32-libs).

Installing Subversion server on Ubuntu...

I need a source control in my local network. No need for fancy http or https. Custom svn protocol should be sufficient.

1) Install Subversion
    $ sudo apt-get install subversion
2) Create directory for my repository
    $ mkdir /home/dirn/svn
    $ cd /home/dirn/svn
    $ mkdir my-repo
3) Create repository by using svnadmin command
    $ sudo svnadmin create /home/dirn/svn/my-repo
4) Create a new group called subversion
    $ sudo groupadd subversion
5) Add your username and www-data into the group
    $ sudo usermod -a -G subversion www-data
    $ sudo usermod -a -G subversion user_name
6) Set permission
    $ cd /home/dirn/svn
    $ sudo chown -R www-data:subversion my-repo
    $ sudo chmod -R g+rws my-repo
7) Edit svnserve.conf file
    $ nano /home/dirn/svn/my-repo/conf/svnserve.conf
8) Uncomment the following line and save the file
    # [general]
# password-db = passwd
9) Edit passwd file
    $ nano /home/dirn/svn/my-repo/conf/passwd
10) Add your svn username and password and save the file
    username = password
11) Run svnserve service
    $ svnserve -d --foreground -r /home/dirn/svn
