Installing Blender In Ubuntu 9.10

Blender is a 3D graphics application used for modelling and creating interactive 3D applications and games.

To install, download the correct package from the official Blender webpage. For Ubuntu (and all 32-bit Linux OS in general), do the following:

1. Download the package form here.

2. Save it anywhere, for example in a directory named Setup_Files in the home directory.

3. Open a terminal, and extract the .tar.bz2 file first.

varsha@varsha-laptop:~/Setup_Files$ tar -xvf blender-2.49b-linux-glibc236-py26-i386.tar.bz2

4. Now cd into the extracted folder, and run the blender executable file.

varsha@varsha-laptop:~/Setup_Files$ cd blender-2.49b-linux-glibc236-py26-i386/

varsha@varsha-laptop:~/Setup_Filesblender-2.49b-linux-glibc236-py26-i386$ ./blender


Another simple alternative is:

varsha@varsha-laptop:~$ sudo apt-get install blender

Replace apt-get with the package manager of the distro you are using and install as a superuser.

That's all. Now enjoy creating your 3D application!

Configuring LAN Connection

During my one-and-a-half-month stay at home I started using a local broadband connection for internet. But all of a sudden to my utter surprise, I saw that the default ethernet connection (named eth0) had vanished, without which, as evident, I won't be able to access internet on returning to college, because, the current broadband settings were manual and I couldn't think of automating everything, as this would interfere with my ease at home.

My fear quite turned true, back at college. A few initial attempts did fail, but the solution was simpler than thought.

1. On the top-panel, right-click the internet connection icon, and select Edit Connections....

2. Click Add.

3. Under the tab IPv4 Settings, select 'Method' Automatic (DHCP) and under IPv6 Settings, select 'Method' Ignore.

Note: For most users, method Automatic would have worked.

4. Connect automatically and Available to all users are optional. Give a suitable name (for example eth0).

5. Click Apply.

These automatic settings, unlike the manual ones, can be used inside any LAN network, as it automatically detects the addresses. If you know the Netmask, Gateway and IP addresses, then you can manually configure, but I prefer automatic settings for LAN.

Including Code Snippets In Blogger

Writing code snippets in Blogger is a real task, for which I found the following site extremely useful:

SimpleCode

Just copy the code and paste it in the first text area and click Process. Then paste the code from the lower text area into your Blogger post, wherever necessary. :)

Although the code, when pasted, may be maroon in colour, you can change it according to what you like.



Deactivating Password Request For Mounting Windows Partitions In Ubuntu 9.10

Mounting Windows partitions in Ubuntu 9.10 prompts for the administrator password by default, which can be deactivated by following the steps given below:

1. Open the concerned file by typing in the terminal the following command.

varsha@varsha-laptop:~$ sudo gedit /usr/share/polkit-1/actions/org.freedesktop.devicekit.disks.policy

2. In the file, search for the line (most probably 34th):

<allow_active>auth_admin_keep</allow_active>

3. Replace the above line with the following line:

<allow_active>yes</allow_active>

4. Save and close the file.

Next time you mount the partitions, they would mount automatically without prompting for the password.
