One of the best rubik Timer with lot of inbuilt options. I took an attempt of using Prisma Puzzle Timer in Ubuntu 14.04.

We can download the jar from this website
Prisma Puzzle Timer

After downloading we can run the timer from terminal using the following command

Move to the downloaded jar file location

cd /home/user/Downloads

and run the jar file by

java -jar PrismaPuzzleTimer0.6.jar

which will invoke the timer .

But everytime , we need to type this command in the terminal to invoke it .

Instead we can create a laucher file which will invoke this timer. For that we need a simple software .


We can download the software using the command

sudo apt-get install alacarte

Once downloaded invoke alacarte from the terminal by typing its name


and click on new item button to create a new launcher.

In the command type java -jar PathToTheJarFile

in my case its java -jar /home/user/Software/PrismaPuzzleTimer.jar

Save and close . With the given Name (in my case its “RubikTimer”) it will be added to the main menu.

You can search for the work RubikTimer in the menu search tab and launch the software by clicking on the file .

Please refer to the images below .

I had Ubuntu 12.04 and Windows 7 running in my system and Ubuntu 12.04 got Crashed .I tried debugging it but couldnt succeed.

I decided to do a fresh install of latest version of Ubuntu and that was Ubuntu 14.04. I created a live USB and installed it in my system .

Installation was quick and easy. But , since i created a new Ubuntu install rather than overridding the existing one , Only 9 GB of space was left with me in the system Where ubuntu 14.04 got installed.

I had access to Ubuntu 12.04 Files as a separate drive, which i doesnt needed. I was looking for some application like Disk Management in windows which would help me to resize my partitions and i edned up with Gparted.

It looked pretty complex stuff for me to delete the partition and free up the space . Luckily , dual boot helped me to do it via Disk Management utitility in windows. I had free space ready with me .

Follow the steps below

1. Open Gparted and authorize it.
2. Right click on the partition which you want to increase
3. Select Resize/Move
4. Enter correct value in New size (It should be less then total unallocated space)
5. Click on start button to complete the action.

I was trying to resize my ubuntu 14.04 partion space using Gparted , where i deleted a partition which had my previous ubuntu install.

Unfortunately, the grub was loading from that partition and after my restart the computer went to the promt with grub rescue menu.

If you face the simillar situation , you can recover your OS grub loader as below.

This link was really helpful for me to boot my ubuntu installation .

Follow the steps given by Amr Amyan.

For me the commands were

set root=(hd0,msdos6)
set prefix=(hd0,msdos6)/boot/grub
insmod normal

where msmod6 is the partition where ubuntu resides. That can be found by ls command .
Try ls(hd0,msdosX) and hit enter. you should be a valid partition . (ext2 partition)

But its not the end. You have just booted up the OS. When you restart you will be back to your grub rescue menu.

So here we have 2 options.

1. Using Live CD or Live USB
2. Using Existing Ubuntu

Since my Ubuntu 14.04 got booted up , i installed boot-repair from terminal by following these commands

sudo add-apt-repository ppa:kranich/cubuntu
sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair

Once its done , open boot repair and select “Recommended Repair” Menu . System will recover Grub and give you a link as well.
NOte down the link and restart your computer.

Bingo !!!!

Even after boot repair you are not getting the boot menu, paste the link to the corresponding email id. Ubuntu support team will help you out !!!.

For developing applications in Django, i needed a good IDE for writing code in python and Pycharm is the IDE that works like a charm.

I downloaded the pycharm tar ball package from here.

Download Pycharm from here

and extract the package as

tar xvf Pycharm*.tar.gz

You got the package untarred but, we gotta check one more stuff.

Pycharm will look for JAVA HOME . Check if java is installed .

java -version

if not , install it with

sudo apt-get install default-jre

And run the script from bin folder.

Ubuntu 12.04 Lts Wifi Issue

Yesterday did a fresh install of ubuntu 12.04 LTS in my dell Laptop. As usual, got into a big trouble .

Previously, when i installed linux mint i got the same issue .. Wifi was not getting connected properly .

This time it was more than that. There was no sign of the word “wireless” over there. But i could recognize that it is because of some driver issue .

Then i tried googling it up and came to know that the issue is quite common and i need to install Broadcom Wireless STA Driver. Then i went to Additional Drivers option and tried to install it .. Again a bad luck . There was some error saying check ‘/var/logs/jockey.log’ . Being a beginner i was not able to crack the issue .

At last , these three commands helped me out ..

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree
sudo modprobe -r b43 && sudo modprobe b43

Issue got resolved . But , even for doing this we need internet. Thats the worst part. Thank god i had wired internet with me .
