Assign keyboard shortcut for Terminal in Fedora

Ctrl + Alt + T was not working as a shortcut for terminal in my fedora 17, I was used to gnome so here is the way to assign a shortcut for terminal in fedora.

Search for "shortcuts" in your launcher you should find the keyboard settings application.

Now click on the add new shortcut button.

 Enter name as Terminal and command as gnome-terminal.

Now the command is created to assign a shortcut double click  the created shortcut in custom shortcut, you can now press the desired shortcut keys to assign it to terminal 

You can assign any number of shortcuts in this manner.

Battery details using Terminal

Recently I installed Xubuntu which being awesome and far better than Ubuntu' s Gnome lacks some of the features like showing estimated battery time remaining.

I tried a lot to  find out a solution for this recently came across a ask Ubuntu thread which describes a way to obtain battery details using Terminal.

Using upower you can get all the battery details.

To view all the details you can use

upower -i /org/freedesktop/UPower/devices/battery_BAT0

Use grep to remove the unwanted details from the above result

upower -i /org/freedesktop/UPower/devices/battery_BAT0 | grep -E "state|time|per"

You can create alias for the same command so that you can run it using just the alias that you gave

alias bat='upower -i /org/freedesktop/UPower/devices/battery_BAT0 | grep -E "state|time|per"'

To permanently add this to your system terminal just copy paste the same command to .bashrc or /etc/rc.local

Permanently adjust screen brightness in Ubuntu 12.04 / Linux Mint 13

This tutorial will help you to adjust the screen brightness in Ubuntu 12.04 / Linux Mint 13 during each boot automatically.

Tested in Intel i7 laptop with Nvidia Graphics Card, this idea will work only if you have a file named brightness in /sys/class/backlight/acpi_video0

To know your systems current brightness level.

cat /sys/class/backlight/acpi_video0/brightness

Change brightness by changing the value 

echo 0 > /sys/class/backlight/acpi_video0/brightness

To permanently set the brightness you can use the rc.loacal script file to change brightness which is executed at each reboot

sudo gedit /etc/rc.local

add the following line above "exit 0" seen at the bottom of the document 

echo 0 > /sys/class/backlight/acpi_video0/brightness

save the file and restart your system.

Proper Nvidia Optimus Drivers for Ubuntu / Linux MInt

Note : These setting where tested @ Asus K53SV ( Nvidia 540M ) , but it should be working for any Nvidia graphics card with Optimus.

I have been using Linux for past two years, I was never satisfied with the battery life and graphics quality of Linux even though I had i7 processor and Nvidia 540M graphics tried lot of Nvidia Installations either they crashed or they crashed my entire system.Now I tried out bumblebee which works perfectly just like a switchable graphics.

Okay lets Install Bumblebee

1. Get rid of all Default driver you already have in your system
   sudo apt-get purge xserver-xorg-video-nouveau
2. Install Bumblebee ppa
   sudo apt-add-repository ppa:bumblebee/stable
3. Update and Install Bumblebee
   sudo apt-get update && sudo apt-get install bumblebee

In case of an error (I got an error related to users addition to group) use these two commands
     sudo usermod -a -G bumblebee $USER
     sudo apt-get install virtualgl-libs:i386 libgl1-mesa-glx:i386 libc6:i386


To run application using Nvidia drivers you can use Optirun command in terminal it takes application name as parameter for example 
To run Vlc 
          optirun vlc & 
Firefox 
          optirun firefox &
I was able to achieve a increase of about 1 hour in my battery life. I have also heard that this can decrease the heating in Dell Laptops,but its a fact that we all done a mistake by selecting a optimus laptop for Linux use even after installing bumblebee you wont to be able to use HDMI output and some other functions that windows provide, I'm not sure may be I haven't come across such solutions yet.

You can Install the Bumblebee UI too!

Cowon iAudio E2 Review

Here is the review for one of the best screen less mp3 player ( ipod shuffle like device).

Sound Quality

Its more or less better than Apple Ipod shuffles music quality. It has better clarity but lacks in maximum sound ( Though the sound will be enough for most people ). This device come with some preset equalizers which can be toggled using a button ( Ipod shuffle lacks this feature ) .
Overall the sound quality GREAT!

Build

Made with plastic kinda material but its really strong ( not as strong as Ipod its metal body).

Formats Supported

1. Mp3
2. Wma
3. Wav
4. Ogg
5. FLAC

Apple shuffle doesnt support most of these formats.


Pros

• Can skip folders using volume buttons ( switch off shuffle press volume button twice within 2 seconds ) this feature is really good for screen less players
• Equalizers
• Can be used as a Key chain or Can be attached to your jean / Shirt buttons 
• Compact design 
• 10 hours of battery life + takes just 90 minutes to charge Full
• This device doesnt require any particular software to transfer data .As a result it can be used with any os through USB connection unlike Apple shuffle which requires iTunes.
• In India E2 comes with one year warranty.

Overall this is a great equipment which is very small good for those who do jogging / gym. Better than Apple shuffle in most of the features. I really recommend this product really satisfied with the quality.

You Can Buy this product in India from these online vendors.

Cat and Terminal

Here's a spiffy little command that can be used to combine files, look at the contents of a file and do limited text editing.

The Linux cat command at first seems so simple as to be unnecessary. In actuality, it is an excellent example of the Unix philosophy: create programs which do one thing and do it well. The thing cat does well is display the contents of a file or files. Many other utilities can handle this task, but none have all the options cat does. First, let's look at the simplest case:

cat /etc/motd

This command will display the contents of the motd (messages of the day) file to your screen. Unlike more (or less), cat will not stop when the screen is full. This is a feature, not a bug. You don't want pauses when redirecting (using the > operator) cat's output to a device, e.g., a printer or modem:

cat /etc/motd > /dev/modem

cat comes from the word conCATenate, which describes one of its best uses: to concatenate or “glue together” two or more files. If you have several individual files about animals you would like to collect together into one file, cat will do the work for you. For example:

cat tiger lion cougar > bigcats

would redirect the concatenation output, containing the three feline files in the specified order, into a new file named bigcats. If you find another file, panther, that needs to be added to the bigcats file, use cat with the append (>>) operator in the following way:

cat panther >> bigcats

Using >> ensures any prior content of bigcats is preserved. The content of panther is appended to bigcats. If you were to use the > operator here, you would replace the contents of bigcats with the contents of panther. Always use >> when you wish to add to the end of an existing file.

Be careful not to use the same file name when redirecting the output of the cat command, or you could lose one of the files. For example, don't do the following:

cat myfile yourfile > yourfile

In this case yourfile gets overwritten by myfile.

Another surprisingly handy use for cat is to redirect standard input like this:

cat > newfile
some notes I want to save in newfile.
CTRL-D

This creates a new file (named newfile). You type as much text as you wish, then type ctrl-D to save the file. You can backspace over mistakes, but you cannot go to a previous line after you press the enter key. I often teach this particular option of cat to novice Unix users, who occasionally need to create simple files, but don't want to learn vi or other simple editors. There may be Unix systems without vi or your favorite editor, but cat is always there.

The operator >> can also be used to append notes to the end of newfile:

cat >> newfile
Adding another note to newfile.
CTRL-D

cat Switches

Like most Unix commands, the behavior of cat can be modified by command line switches. If you use the diff command to compare files, it will show you the numbers of lines that differ between the files. However, most files don't have line numbers. Use cat with the -n switch to number each line of a file:

cat -n kittens > num_kittens

The file num_kittens is kittens with a number in front of each line, including blank lines. Use the -b switch to number only lines that are not blank.

One last cat trick: using the -v switch will show you “hidden” characters, such as control characters that may not show up in your editor. Try this experiment:

cat > catestv
CTRL-v testing CTRL-O Testing esc-b
CTRL-D

If we use cat to view the file, we see only the normal text:

cat catestv
Testing Testing

To see what's actually in the file, use the -v option:

cat -v catestv
^V Testing ^O Testing ^[b

Here, a ^ in front of a character signifies a control character. (CTRL-[ is the same as ESC).

Finding files in Linux system using terminal

Terminal Rocks !

You can find any find of files in your Linux system using the terminal, which to me is much faster and easier than slow nautilus search which lacks usability.

$ locate search-term 

Locate ( slocate in some distribution instead of locate ) is the command used to search files inside a Linux system, which finds any kind of file to match the given keyword. You can also update the search index by using the command
 
$ sudo updatedb

Asus K53SM SX016D

Asus K53SM-SX016D

Review

Case

K53SM comes with tough aluminium case which is lighter and satin in finish.Its not of some kind material which can attract dust or finger prints.I'm personally satisfied with its case and design.Its better than Dell XPS casing and moreover similar to that of HPs casing.Also, K53SM was designed according to the IceCool technology. This is responsible for the cool palm resting area. The components, which release a lot of heat, were positioned in such a way that the heat is able to dissipate.

The case of our tested device is very stable. The surface can only be dented marginally. Even the area around the optical drive, which is often the biggest weak spot as far as stability is concerned, can withstand localized pressure. This is valid for the bottom as well as the top of the notebook. Additionally the case is also not bendable.
The display lid in comparison can be dented considerably in the middle, which is within limits though. The hinges hold the display firmly in place. When adjusting the opening angle the display only wobbles a small amount.

The notebook itself stays completely still on the desktop, which is amongst other things due to the considerable weight of 2.7 kilograms. Altogether the manufacturing quality leaves a high quality impression.

Proccessor 

K53SM series comes with I5 or I7 processor which is quiet fast for normal computing purpose.
Regarding K53SV-SX016D I have core-i7 2670qm processor with 2.2Ghz clock and turbo boosts upto 3.4Ghz.The 2670qm is about 10% better than 2630qm which is cheaper with 2.0Ghz clock speed.


Graphics Card

K53SV series come with Nvidia Geforce graphics card with optimus technology.In SX016 it comes with 630M Geforce with 2GB of dedicated graphics memory which is listed in the class 2 graphics card in notebookcheck website.This is a rollover version to 540M .This card can handle most of the currently available games in the market without any lag.Personally I tried Assasins Revelations, Fifa 12, Akraman city with higher graphics settings all of them worked without any problem.While playing crysis I was able to notice some lags when graphics settings are set to ultra.

Ram and Hard-Disk 

The HDD that Asus supply with this series is 5400rpm Western Digital made with 500 or 750 GB of space.But this one lacks the response of the 7200rpm one which is available in Dell Xps.I have noticed in my laptop it responds too slowly at times when I tries to copy or move some files.

In SX016 model you will get 750GB HDD and 8GB  RAM.


                              
Connectivity 

K53SV has all the modern connectivity technologies within it namely the Bluetooth and WiFi.It comes with  Bluetooth 3.0 version in selected models.In my model ie SX016 it comes with Bluetooth V3.0.

In order to enjoy watching HD movies on an external monitor, there are a VGA output as well as an HDMI interface available.

Communication

The possibilities to connect to a network or to communicate with other devices are more on the sparse side. The Realtek PCIe GBE Family Controller (Gigabyte LAN) makes it possible to connect a LAN cable, while wireless LAN is made possible by the Atheros AR9285 Wireless Network Adapter (bgn).

Accessories

When it comes to the included accessories the Taiwanese manufacturer has made some savings. Along with the notebook and the AC adapter, there is merely some printed documents such as the handbook in the box

Input Devices

Keyboard

The chiclet keyboard has a complete alpha-numeric keypad. The somewhat smaller keys have a generous distance between them, but are a little slippery. To make up for this the pressure point is nicely crisp though. The keys have a rather hard end stop, and a medium key travel. Frequent typers should be able to get used to the included chiclet keyboard over time.

Touchpad

The touchpad is below the space bar, and is ideally suited to the design of the notebook. The PalmProof technology is supposed to interpret unintended contact with the sensitive surface as accidental, and does not process this. The cursor is therefore only supposed to move when a finger operates the touchpad. The PalmProof technology was also able to prove itself in practice, and there were no empty promises. Nevertheless, vertical and horizontal scroll bars are missing. The two mouse buttons unfortunately only have a very short key travel.

Display

The 15.6 inch display has a model description of CPT14C7. The HD panel has a maximum resolution of 1366 x 768 pixels. Higher resolutions are possible with an external display. The panel has a 16:9 aspect ratio, and has a reflective surface. The contrast of the glare-type display lies at a mere 181:1, and thus makes it into the average range of comparable devices at the best of times.

Is the Asus K53SV equipped for outdoor use with its 15.6 inch display? The answer to this question is rather on the disillusioning side: Within limits. Those that want to use the K53SV outdoors in the open, will at the very least have to find a place in the shade. Under direct sunlight users will see themselves on the display more than anything else.

The viewing angle stability doesn't live up to expectations either. 

Temperature

As already mentioned the Asus K53SV makes use of the IceCool technology. This is supposed to keep the surfaces, and particularly the palm resting area, cool at all times. In an idle state the case does indeed stay relatively cool on the top surface with an average of 25.2 degrees Celsius, as well as the bottom surface with an average of 25.1 degrees Celsius.

Warranty

Asus provides a 24 month warranty with pickup & return (battery 1 year) for this model in the K-series.

Verdict

The Asus K53SV multimedia notebook in its SX016 version left amixed impression. For a price of around 52000 rupees buyers receive a useful device, which does have its weaknesses though.

What was able to impress us was the stable case made of aluminum. The palm resting area never gets too warm thanks to the IceCool technology. The system noise is also a positive aspect. What dulls the good impression is the reflective display with a meager brightness, and narrow viewing angles. 

The performance of the mainstream model with an Intel Core i7 2670qm, as well as an Nvidia GeForce GT 630M, appears to be sufficient for most application scenarios.

Inorder Traversal of Binary Search Tree

 

To traverse a non-empty tree in inorder the following steps are followed recursively.

• Visit the Root
• Traverse the left subtree
• Traverse the right subtree

The inorder traversal of the tree shown below is as follows.

Algorithm



The algorithm for inorder traversal is as follows.


Struct node
{
struct node * lc;
int data;
struct node * rc;
};


void inorder(struct node * root);
{
if(root != NULL)
{
inorder(root-> lc);
printf("%d\t",root->data);
inorder(root->rc);
}
}


So the function calls itself recursively and carries on the traversal.

Binary search tree and its implementation

Binary tree

A tree is a finite set of nodes having a distinct node called root.

Binary Tree is a tree which is either empty or has at most two subtrees, each of the subtrees also being a binary tree. It means each node in a binary tree can have 0, 1 or 2 subtrees. A left or right subtree can be empty.

A binary tree is made of nodes, where each node contains a "left" pointer, a "right" pointer, and a data element. The "root" pointer points to the topmost node in the tree. The left and right pointers point to smaller "subtrees" on either side. A null pointer represents a binary tree with no elements -- the empty tree. The formal recursive definition is: a binary tree is either empty (represented by a null pointer), or is made of a single node, where the left and right pointers (recursive definition ahead) each point to a binary tree.

Representation of Binary Tree

The structure of each node of a binary tree contains one data field and two pointers, each for the right & left child. Each child being a node has also the same structure.

Struct node
{
struct node *lc ; /* points to the left child */
int data; /* data field */
struct node *rc; /* points to the right child */
}



1. Array Representation of Binary Tree: 

A single array can be used to represent a binary tree. 

For these nodes are numbered / indexed according to a scheme giving 0 to root. Then all the nodes are numbered from left to right level by level from top to bottom. Empty nodes are also numbered. Then each node having an index i is put into the array as its ith element. 

In the figure shown below the nodes of binary tree are numbered according to the given scheme. 

The figure shows how a binary tree is represented as an array. The root 3 is the 0 th element while its left child 5 is the 1 st element of the array. Node 6 does not have any child so its children ie 7 th & 8 th element of the array are shown as a Null value. 

It is found that if n is the number or index of a node, then its left child occurs at (2n + 1) th position & right child at (2n + 2) th position of the array. If any node does not have any child, then null value is stored at the corresponding index of the array.

/* Prorgram to implement the above array representation * /

Struct node
{
struct node * lc;
int data;
struct node * rc;
};
struct node * buildtree(int); /* builds the tree*/
void inorder(struct node *); /* Traverses the tree in inorder*/
int a[]={ 3,5,9,6,8,20,10,/0,/0,9,/0,/0,/0,/0,/0,/0,/0,/0,/0,/0,/0};


void main( )
{
struct node * root;
root= buildtree(0);
printf(“\n Inorder Traversal”);
inorder(root);
getch( );
}


struct node * buildtree(int n);
{
struct node * temp=NULL;
if( a[n] != NULL)
{
temp = (struct node *) malloc(sizeof(struct node));
temp-> lc=buildtree(2n + 1);
temp-> data= a[n];
temp-> rc=buildtree(2n + 2);
}
return temp;
}


void inorder(struct node * root);
{
if(root != NULL)
{
if(root!= NULL)
{
inorder(root-> lc);
printf(“%d\t”,root->data);
inorder(root->rc);
}
}

Asus K53SV SX520 Review

I bought my K53SV about a week back thought of writing a review as I didn't find any reviews from India for the specific model till now.

Transfer files between PC and Android device over WiFi

Transferring files between your Android and PC over wifi

To do this over WiFi I recommend you to download and use SwiFTP .

Connect to your PC using wifi (This may be using a router to a network where your PC is also connected or simply connect it ).

Install SwiFTP from the market

Open the SwiFTP application in your android.

Setup the settings for connections in SwiFTP

• Set a username.
• Set a password
