Avro Keyboard 4.5.3 and UniBijoy

Avro Keyboard

Avro Keyboard is the most popular Bangla typing software. It is used world-wide by Bangla speaking people. Avro Keyboard project is developed and maintained by OmicronLab which they deliver free. Another software named Bijoy Keyboard exists on the market. Bijoy is losing because of it’s owner’s harsh business policies. There are several allegations against the proprietor of closed source Bijoy software. He issued a lawsuit against Avro Keyboard along with making abusive comments against Avro Keyboard and its developers in public.

People who are used to Bijoy Keyboard layout use Unibijoy, a fixed tradional keyboard layout with Avro. There are many differences between Bijoy Keyboard Layout and UniBijoy layout. Nobody finds a reason to patent keyboard layouts since these keyboard layouts aren’t productions of neither creativity nor merit! A patent should always protect a unique work of merit.

Because of his (proprietor of Bijoy) desperate attempts to remove UniBijoy from Avro software he succeeded to slap the pride of Bangla speaking people’s right to choose their desired keyboard layouts. Bangla speaking people are disappointed on this kind of business with Bangla language. Bangla is the only language for the love of which many Bangla speaking people were martyred in 1952. They are remembered with great honors, respects and love every year on 21st February which is also founded as International Mother Language day. Hence this is never expected that software for writing Bangla will be a part of Business.

Avro Keyboard has a new release 4.5.3. UniBijoy adopters are worrying about the removed keyboard layout. But there’s a way out! Download the new software from the below links.

Avro keyboard is available at the following URL:

Because omicron-lab server is down (till 31st August, 2010) because of bandwidth limit (sign of popularity, huh!) exceed you have to download avro keyboard from the following links:

How to use UniBijoy in Avro
There’s a component in Avro Keyboard called Keyboard Layout Editor. You can create your own keyboard layout in Avro. Also you can save the keyboard as a file and share with others.

Be careful. If it looks like Bijoy Keyboard the uncle may mind.

Hence it’s your responsibility if you are a victim of new lawsuit by using a keyboard layout like mine!

Here’s a Unibijoy like keyboard layout you can download and use for writing Bangla.
After downloading the keyboard layout copy it to avro’s keyboard layout folder:
C:\Program Files\Avro Keyboard\Keyboard Layouts
If your installation directory is different it will be different too.

Now exit avro keyboard and start again. Select UniBijoy from Keyboard Layout menu.

You’re done. Now you can start typing Bangla with any application that supports Unicode.

Booting Solaris Operating System using Windows Boot Loader - redirect

Cannot boot Ubuntu 10.04 after installation of Ubuntu or after installation of Windows Seven

You have just installed Ubuntu 10.04 but you cannot boot to it. System boot straights to Windows Seven and you are feeling deceived. I also faced this issue.

May be there’s a problem with Ubuntu 10.04 distro that’s happening with some PCs having Windows Seven. Well here’s a fix. Follow the steps.

Ø Boot the system using Live CD.

Ø Press Alt+F2 and enter gnome-terminal command. And continue by entering:

$ sudo fdisk -l

It shows partition table. Here’s mine.

/dev/sda1 29 8369 66999082+ 83 Linux
/dev/sda2 * 8370 13995 45190845 7 HPFS/NTFS
/dev/sda3 13996 14593 4803435 5 Extended
/dev/sda5 13996 14593 4803403+ 82 Linux swap / Solaris

Now mount Linux boot partition. As you can see from the output of previous command it was sda1 for my system.

$ sudo mount /dev/sda1 /mnt
$ sudo mount --bind /dev /mnt/dev
$ sudo mount --bind /proc /mnt/proc

Now chroot into the enviroment:

$ sudo chroot /mnt

After chrooting, we need not add sudo before commands.
You may want to edit /etc/default/grub file to fit your system (timeout options etc)

# vi /etc/default/grub

After edition press ESC & then :wq to store and exit. Now install/recover Grub2 via command:

# grub-install --recheck /dev/sda

Now you can exit the chroot, umount the system and reboot your system:

# exit
$ sudo umount /mnt/dev
$ sudo umount /mnt/proc
$ sudo umount /mnt
$ sudo reboot

How to concatenate/merge Solaris 10 DVD image segments

Here's an example how to merge segments in Unix or Unix like systems:

[ ]$ cat sol-10-u8-ga-sparc-dvd-iso-a sol-10-u8-ga-sparc-dvd-iso-b > \

In Windows system, concatenate the files using the following command:

D:\> copy /b sol-10-u8-ga-x86-dvd-iso-a + sol-10-u8-ga-x86-dvd-iso-b \

The result is a true ISO image that you can use to burn a DVD.
Use software like Nero or MagicISO to burn the DVD in Windows.
