The WordPress.com stats helper monkeys prepared a 2013 annual report for this blog.
Here’s an excerpt:
A San Francisco cable car holds 60 people. This blog was viewed about 2,300 times in 2013. If it were a cable car, it would take about 38 trips to carry that many people.
If you had linux installed and later thought of installing Windows, it will overwrite your grub boot loader by default.
The fix is quick and easy. So, I would like to document the easy steps for reference.
Previously, I wrote for similar fixing but in Bangla উবুন্তু ৯.১০ : কারমিকে আপগ্রেড করায় সৃষ্ট সমস্যা এবং প্রতিকার
For this solution you gotta have a live CD or USB bootable through which you can Run Ubuntu/Lubuntu (or Mint etc debian distros).
1. Boot up your machine with the LiveCD/USB, you can run the installer just to see the device on HDD containing your linux installation.
It would be something like /dev/sda1 and in ext4.
2. If you haven’t run the installer, you can see the partition table using gparted. Press Alt-F2 and type gparted and hit Enter.
If it tells you that gparted needs root permission then, instead of just ‘gparted’ type in ‘gksu gparted’ and hit enter. If you wanna know about gksu. Now if you have identified your linux’s / folder partition go to next step.
3. On your terminal (hit Ctrl+Alt+T to pop open) type: sudo mount /dev/sdXY /mnt here, replace X with a,b,h etc as you found above. Y is the number. For mine it was: sudo mount /dev/sda1 /mnt
4. You haven’t done anything destructive or permanent in the above steps. At this step you will try to revive the old grub. If your ‘/’ (root) folder’s location was /dev/sda1, now you will use it as /dev/sda to refer to the device as a whole. NOT WITH NUMBER
So, at the terminal you will type: sudo grub-install –root-directory=/mnt/ /dev/sdX
It it showed success. You are done. Reboot machine and you will see your old grub2 boot loader. But, Windows might not appear there. Dont panic! Go to next step to fix. 🙂
5. Boot up in your good old Ubuntu. And fire up your terminal again. Type: sudo update-grub
It will fetch your windows to the boot loader as well. Cheers!
You just installed Windows over your Ubuntu box and that ruined your boot menu leaving Windows as your only option. So, you are forced to use Windows.
Now, every time that happens you gotta find a reliable link that actually works. So, I decided to blog it instead of just sharing on twitter or FB, which I do millions and I never would go browse them while I am at office or with quality company (I wont like someone stalk behind me or let them think I am wasting time at facebook!).
Enough talks, the only valuable input to this post is, I have used “Universal USB Installer” and that actually work! Others should work too at this HowToGeek article.
I was having a some sort of hell trying to install Doctrine via PEAR lately.
$sudo pear channel-discover pear.doctrine-project.org
$sudo pear install -o pear.doctrine-project.org/DoctrineORM
Was giving me errors like:
Package "pear.doctrine-project.org/DoctrineORM" dependency "pear.symfony.com/Console" has no releases
Package "pear.doctrine-project.org/DoctrineDBAL" dependency "pear.symfony.com/Console" has no releases
doctrine/DoctrineORM requires package "pear.symfony.com/Console" (version >= 2.0.0)
doctrine/DoctrineORM requires package "pear.symfony.com/Yaml" (version >= 2.0.0), installed version is 1.0.6
doctrine/DoctrineDBAL requires package "pear.symfony.com/Console" (version >= 2.0.0)
No valid packages found
install failed
See, for some unknown reason the versions are not correct for the dependencies. Tried the solutions as stated in this StackOverflow topic for updating PEAR, but didn’t help!
Tried to remove/purge pear. But it didn’t help. Tried to install the Console, Yaml etc separately, also didn’t help.
Then when I tried to purge pear again I got the following error:
Removing php-pear …
Purging configuration files for php-pear ...
dpkg: warning: while removing php-pear, directory '/usr/share/doc/php5-common/PEAR' not empty so not removed
dpkg: warning: while removing php-pear, directory '/usr/share/php/.channels' not empty so not removed
There were some other folders which was reported to be not empty:
/usr/share/php/.registry/
/usr/share/php/.channels/.alias
/usr/share/php/data
/usr/share/doc/php5-common/PEAR/Archive_Tar/docs
/usr/share/doc/php5-common/PEAR
So, I removed them all!
Now, I again installed pear.
sudo apt-get install php-pear
Fingers crossed…
Added Doctrine channel: sudo pear channel-discover pear.doctrine-project.org
And it didn’t say this time that channel is already in registry. Smiling…
Now to fire up doctrine installation, hope this time it works…
sudo pear install -o pear.doctrine-project.org/DoctrineORM
et viola! it did!

So, thats it.
কালীগঞ্জ, গাজীপুর এবং নারায়ণগঞ্জ ভ্রমণ, a set on Flickr.
This visit was mainly to Kaligonj upazilla of Gazipur (btw dont get confused that if I am from Gazipur because my name is Ghazi [notice the spelling!] 😉 ). I am in fact descendant of Ghazi family of Dohar upazilla of Dhaka.
While returning we decided that we’d take different route and will not come back through Uttara. Rather we traveled via Dhaka bypass road and Kanchan bridge then we visited historical Murapara College of Narayangonj. In total it was a 100km round trip to Gazipur.
We visited 4/5 chapels and churches of Kaligonj upazilla.
My escort was Pervez Robin of Joypara, Dohar. Who actually initiated this travel idea. So, all thanks goes to him.
