Know your Battery status the command line way


Well no big deal:-). The battery information can be easily got by clicking on the battery icon in your Ubuntu's taskbar. The good thing here is you will know from which file the information of the battery is fetched.
To know the current state of the battery:
pradeep@pradeep-laptop:~$ cat /proc/acpi/battery/BAT0/state
present: yes
capacity state: ok
charging state: charging
present rate: 0 mA
remaining capacity: 3599 mAh
present voltage: 12578 mV

To know all the info regarding your laptop battery:
pradeep@pradeep-laptop:~$ cat /proc/acpi/battery/BAT0/info
present: yes
design capacity: 4400 mAh
last full capacity: 3789 mAh
battery technology: rechargeable
design voltage: 10800 mV
design capacity warning: 185 mAh
design capacity low: 129 mAh
capacity granularity 1: 56 mAh
capacity granularity 2: 3604 mAh
model number: VE06047
serial number: 453
battery type: LION
OEM info: STL-LG22

Ahh, 3789mAh/4400mAh = 87%, Not bad after 1.5 years of torture to my lappy;-). Let me know your' s too.

Twittering the command line way


As you might have noticed my previous post was browsing the command line. Now lets see how to twitter the command line way:-);-)
At first you need to install cURL.(a client for getting files from servers) to post to Twitter through the Terminal which can be installed using the following command:

pradeep@pradeep-laptop:sudo apt-get install curl

With cURL installed, you can post to Twitter from the terminal window by using the following syntax:

pradeep@pradeep-laptop:curl -u yourusername:yourpassword -d status="Your Message Here"

You will receive a response containing the XML coding for your post which acts as a confirmation that your post was submitted.

So have fun twittering the command line way:-)

Post in your reviews:-)

The command line way of browsing


One of the best things in Linux I like is the command line way of doing things. Well now I can do almost all my work from the terminal and the latest being browsing and chatting. The only thing I cannot do is viewing images and watching videos which soon might be possible:-).
So how do I browse from my terminal??? I thought was it possible? I have realised lately there's help for everything and anything on Linux. After doing a small research I found out this cute command line app called "Elinks"(command line browser)

Ever wondered how fast the browser Elinks is ??? No pop ups, no images, but absoultely cool plain test views,option to see images using eog(Eye Of Gnome) , tabbed browsing, history, bookmarks, history : everything one might need in a modern day browser. It doesn't crash , doesn't require any extra plugins for working. Actually above anything else its the speed of browsing is what that beats me ! Brilliant! Don know what adjective would describe the power of elinks. Check out the google page opened on elinks.
Accessing my Gmail account is fun in elinks. So damn fast!!
"finch" is a command line chat client which is the same as pigdin.:-)

elinks can be installed on your ubuntu as follows:
#pradeep@pradeep-laptop: sudo apt-get install elinks

PS: I agree that GUI way of doing things is friendly,easy and all. But after a few tries the command liners are easy to use , more productive and damn cool!!!

Always try and do things differently:-);-)

SMS Typing


Of late I have been solving a lot of problems. Here s a problem which you guys can solve.

Cell phones have become an essential part of modern life. In addition to making voice calls, cell phones can be used to send text messages, which are known as SMS for short. Unlike computer keyboards, most cell phones have limited number of keys. To accommodate all alphabets, letters are compacted into single key. Therefore, to type certain characters, a key must be repeatedly pressed until that character is shown on the display panel.

In this problem we are interested in finding out the number of times keys on a cell phone must be pressed to type a particular message.

In this problem we will assume that the key pad of our cell phone is arranged as follows.


| | abc | def |


| ghi | jkl | mno |


| pqrs | tuv | wxyz |


| |sp | |


In the above grid each cell represents one key. Here SP means a space. In order to type the letter ‘a’, we must press that key once, however to type ‘b’ the same key must be repeatedly pressed twice and for ‘c’ three times. In the same manner, one key press for ‘d’, two for ‘e’ and three for ‘f’. This is also applicable for the remaining keys and letters. Note that it takes a single press to type a space.

The first line of input will be a positive integer T where T denotes the number of test cases. T lines will then follow each containing only spaces and lower case letters. Each line will contain at least 1 and at most 100 characters.

For every case of input there will be one line of output. It will first contain the case number followed by the number of key presses required to type the message of that case. Look at the sample output for exact formatting.

Sample Input : Sample Output

welcome to ulab : 29

good luck and have fun : 41

Bash SpellChecker


Reason for this post is that i tend do a lot of typing mistakes while typing at the terminal:-).
Spell checking in bash can be enabled adding the following line below into your bashrc file

shopt -s cdspell

#pradeep@pradeep-laptop:gedit ~/.bashrc

Add the command mentioned above to the end of the file and save.

That’s all :)

If you want to enable this for all the users, then append this to your /etc/bash.bashrc (in Ubuntu) or /etc/bashrc (in Fedora). Of course, you need the root privilege to edit the files in /etc.

Now try these
cd /hoem
cd /hoe

Ain't it cool.

So by the way what is a bashrc file?
Ok in short it is a script which is run by the bash shell when ever a terminal is invoked once you login.
To know more please see /usr/share/doc/bash/INTRO.gz as in "Ubuntu 9.04". Not sure about other versions. It should be the same according to me.

Microsoft Visio


Ok i don usually like writing about microsoft stuff:-). But saw my friend amarnath installing this software, so writing:-)

Microsoft Visio (pronounced VIZ-ee-oh, not VIZH-ee-oh) is a diagramming program for Microsoft Windows that uses vector graphics to create diagrams. It is currently available in two editions: Standard and Professional.

The Standard and Professional editions both share the same interface, but the latter has additional templates for more advanced diagrams and layouts as well as unique functionality that makes it easy for users to connect their diagrams to a number of data sources and display the information graphically.[1][2]

Microsoft acquired Visio Corporation in 2000. Visio 2007 was released on 30 November 2006. Also released alongside version 2002 were Enterprise Network Tools, an add-on product enabling automated network and directory services diagramming, and the Visio Network Center, a Web site where users could locate the latest network documentation content and exact-replica network equipment shapes from 500 leading manufacturers.[3] The former has been discontinued, while the latter's shape-finding features are now integrated into the program itself.[4]

Microsoft has revealed that the next version of Microsoft Visio will feature the ribbon user interface

Vim plugin you must install


Ok why I am writing this post.Two reasons for it:
1) We have a Web Programming Lab this semester
2) I hardly use windows now:-). Using windows has exponentially decreased:-)

Snipmate.vim is probably the best snippets plugin for vim. A snippet is a piece of often-typed text or programming construct that you can insert into your document by using a trigger followed by a tab. It was written by Michael Sanders.

Here is an example usage of snipmate.vim. If you are a C programmer, then one of the most often used forms of a loop is “for (i=0; condition ; i++) {}”. Without snippets you’d have to type this out every time. Even though it takes just another second, these seconds can add to minutes throughout the day and minutes can add to hours over longer periods of time. Why waste your time this way? With snippets you can type just “for tab” and snipmate will insert this whole construct in your source code automatically! If “i” or “n” weren’t the variable you wanted to use, you can now use tab and shift-tab to jump to next/previous item in the loop and rename them!

Michael also created an introduction video for his plugin where he demonstrates how to use it. Check it out:

snipMate.vim Introductory Screencast from Michael Sanders on Vimeo.

How to install snipmate.vim?

To get the latest version:

1. Download
2. Extract to ~/.vim (on Unix/Linux) or ~/etc/vim (wherever vim is installed)
#pradeep@pradeep-laptop: sudo unzip -d ~/etc/vim (provided is in your HOME folder else provide the desired path)
3. Run :helptags ~/.vim/doc or ~/etc/vim/doc
4. Restart Vim.

The plugin comes with predefined snippets for more than a dozen languages (C, C++, HTML, Java, JavaScript, Objective C, Perl, PHP, Python, Ruby, Tcl, Shell, HTML, VimScript). Be sure to check out the snippet files in the “snippets” directory under your ~/.vim or ~\vimfiles directory.

If you need to define your own snippets (which you most likely will need), create a new file named “language-foo.snippets” in the “snippets” directory. For example, to define your own snippets for C language, you’d create a file called “c-foo.snippets” and place snippets in it.

To learn about snipmate snippet syntax, type “:help snipmate” and locate the syntax section in the help file.
Have Fun!

Install Apache webserver,mysql,perl and php


For all those who dont have apache server,mysql,perl and php on your Linux OS here's a way you can install.
People who have installed Fedora 8/9[Full installation] all the above gets installed automatically. But if you have installed other distributions like Ubuntu, Open SUSE, Red Hat etc, here is a way you can do.

If you install the above softwares separately its a very tedious job believe me. But you need not do that. The idea was suggested by my class mate Abdul Munim. There is a package by name XAMPP which installs everything including many cool things.So how do you go about it

So wat is XAMPP??
XAMPP is an easy to install Apache distribution containing MySQL, PHP and Perl. XAMPP is really very easy to install and to use - just download, extract and start.

So how do you go about it?
At first you need to download the package file.You can find the file: here
Now copy the file to your home directory.Now you are three steps away:-)

Step 1: Installation
Go to a Linux shell and login as the system administrator root:

Extract the downloaded archive file to /opt:
#pradeep@pradeep-laptop:tar xvfz xampp-linux-1.7.1.tar.gz -C /opt

Warning 1: Please use only this command to install XAMPP. DON'T use any Microsoft Windows tools to extract the archive, it won't work.
Warning 2: already installed XAMPP versions get overwritten by this command.

Step 2: Start
To start XAMPP simply call this command:
pradeep@pradeep-laptop:/opt/lampp/lampp start

You should now see something like this on your screen:
Starting XAMPP 1.7.1...
LAMPP: Starting Apache...
LAMPP: Starting MySQL...
LAMPP started.

Step 3: Test
OK, that was easy but how can you check that everything really works? Just type in the following URL at your favourite web browser:


Now you should see the start page of XAMPP containing some links to check the status of the installed software and some small programming examples.

You are done now. If you any queries/problems regarding the installation,please post in the comments and i will try to fix the problem:-)

Power of Yahoo Pipes


Was wondering from many days what is this Yahoo Pipes all about. Knew it is something special. When i used it i was completely shocked. Its such a powerfull tool!! How can i describe it???

Pipes is a free online service that lets you remix popular feed types and create data mashups using a visual editor. You can use Pipes to run your own web projects, or publish and share your own web services without ever having to write a line of code.

Where does pipe come into play??
Suppose you are only interested in cricket and football news, Generally when you visit a sports website you see news associated with every sport. With yahoo pipes you can customise your results according to your needs with data inputs from various sports websites. The pipe i created is below:

An another pipe which u guys can create is regarding movie theatres. There are many multiplexes/theatres in Bangalore like Inox,PVR,Fun Cinemas etc.. All of them will have their own websites. You can obtain data from all these websites and create a pipe which gives you info about which movie is in which theatre etc!

Well source of input need not to be from websites alone. It could be a data from feeds of a site, google search results ,yahoo search results and also data from online spread sheets etc.
Once u create your pipe you can publish it and add it google reader, google homepage, yahoo page or embedd in your webisite

Yahoo Pipes is so simple and powerful that any can use learn and develop their own application. This one blog post of mine is not enough to describe the Yahoo Pipes. The feel of you guys learnin and designing your own pipes is completely different. So go ahead and give a try.

To get you started with watch this intro video:

Torrent2exe- convert ur torrent to an exe file and download


This one's a Beauty!!! True beauty. Have you ever wondered of converting ur torrent files to an exe file!! Yes it's possible and this wonderful site does it.

Well why convert a torrent file to an exe file??

One reason is because i use a usb modem for browsing, and if i download using bit-torrent or any other torrent client i hardly get a speed of 5 kbps.After converting it to an exe file and started the download i got a pretty good speed of 50 kbps and more depending on the seeds.

Second reason, you’ll find it hard to believe but there are a great number of people who are still not familiar with the whole concept of using and downloading with torrents. This popular file-sharing method has been around for sometime but I still get a lot of questions such as: “What now? I downloaded the torrent but nothing is happening.” I assume it’s because of the fact that downloading files via torrent is not as straightforward as downloading files directly from the server or from the web.Using this service, users can download files with the torrent protocol without the need to install a torrent client.

Well its very use to use. Go to the website torrent2exe, paste the link of the torrent or upload the torrent file already there on your computer and convert it to an exe file. Then download the exe file which is hardly 500kb. Double click on the exe file to start the download. You can also resume and pause the downlaod. No torrent clients required at all!! Isn't this cool!!Post in your comments and let me know about ur experience with this.

show RSS- download ur favourite Tv Shows


I had written a post on feed my torrents which kept track of the latest tv show torents and you could retrieve with your RSS reader. Unfortunately feed my torents is no longer working. Well no worries i found yet another one which performs the same task as feed my torrents. Its called the show RSS.

showRSS is a web service that allows you to keep track of your favorite TV shows from a website or from a RSS reader. After registering (and logging in!), you'll have to select what are the TV shows that you want to track and then you'll just have to subscribe to your feed with any RSS reader (Google Reader, your browser...) or even with your torrent client (for example, Āµtorrent supports RSS feeds for automatic downloads). You can also browse latest torrents for your TV shows from this website, instead of using the RSS feed, or you can use both as well.

6th Sense!!!!


What comes to your mind when you hear the word sixthsense..Sometimes you anticipate something is going to happen like for example someone is following you or it might rain etc... So how how do you relate sixth sense with technology??? I don't how many of you have seen the movie The Minority Report starring Tom Cruise.. In the movie you find Tom Cruise using cool gadgets where he uses gestures to perform lot of things.. You also digital newspapers where you can watch live news.. Do you think those things were possible???... The answer is YES...MIT media labs has an answer for it:-) 

So what is this sixth sense about???

We've evolved over millions of years to sense the world around us. When we encounter something, someone or some place, we use our five natural senses to perceive information about it; that information helps us make decisions and chose the right actions to take. But arguably the most useful information that can help us make the right decision is not naturally perceivable with our five senses, namely the data, information and knowledge that mankind has accumulated about everything and which is increasingly all available online. Although the miniaturization of computing devices allows us to carry computers in our pockets, keeping us continually connected to the digital world, there is no link between our digital devices and our interactions with the physical world. Information is confined traditionally on paper or digitally on a screen. SixthSense bridges this gap, bringing intangible, digital information out into the tangible world, and allowing us to interact with this information via natural hand gestures. ‘SixthSense’ frees information from its confines by seamlessly integrating it with reality, and thus making the entire world your computer. 

The SixthSense prototype is comprised of a pocket projector, a mirror and a camera. The hardware components are coupled in a pendant like mobile wearable device. Both the projector and the camera are connected to the mobile computing device in the user’s pocket. The projector projects visual information enabling surfaces, walls and physical objects around us to be used as interfaces; while the camera recognizes and tracks user's hand gestures and physical objects using computer-vision based techniques. The software program processes the video stream data captured by the camera and tracks the locations of the colored markers (visual tracking fiducials) at the tip of the user’s fingers using simple computer-vision techniques. The movements and arrangements of these fiducials are interpreted into gestures that act as interaction instructions for the projected application interfaces. The maximum number of tracked fingers is only constrained by the number of unique fiducials, thus SixthSense also supports multi-touch and multi-user interaction. 

The SixthSense prototype implements several applications that demonstrate the usefulness, viability and flexibility of the system. The map application lets the user navigate a map displayed on a nearby surface using hand gestures, similar to gestures supported by Multi-Touch based systems, letting the user zoom in, zoom out or pan using intuitive hand movements. The drawing application lets the user draw on any surface by tracking the fingertip movements of the user’s index finger. SixthSense also recognizes user’s freehand gestures (postures). For example, the SixthSense system implements a gestural camera that takes photos of the scene the user is looking at by detecting the ‘framing’ gesture. The user can stop by any surface or wall and flick through the photos he/she has taken. SixthSense also lets the user draw icons or symbols in the air using the movement of the index finger and recognizes those symbols as interaction instructions. For example, drawing a magnifying glass symbol takes the user to the map application or drawing an ‘@’ symbol lets the user check his mail. The SixthSense system also augments physical objects the user is interacting with by projecting more information about these objects projected on them. For example, a newspaper can show live video news or dynamic information can be provided on a regular piece of paper. The gesture of drawing a circle on the user’s wrist projects an analog watch. 

The current prototype system costs approximate $350 to build. 

Just watch the video below for what all you could do with this device:-).The video explains it all.

Smarter Wikipedia adds a "Related Articles" box to the mass-edited encyclopedia's left-hand menu, helping you quickly dig into and around a topic—or easily start a long spiral of Wiki-traveling.

Assuming you can responsibly break away from the big gray information machine, Smarter Wikipedia is a helpful navigational tool. Beyond the "Related Articles" box, the add-on can search Wikipedia (or Wikipedia's pages via customized Google query) for any term you highlight and right-click on. The add-on is built small and light, too, as its author points out, aiming to put little drag on your open-source browser.

Smarter Wikipedia is a free add-on, works wherever Firefox does

  • Easily install to USB, Zip or hard drive media.
  • Booting from CD (or DVD), the CD drive is then free for other purposes.
  • Booting from CD (or DVD), save everything back to the CD.
  • Booting from USB Flash drive, minimise writes to extend life indefinitely.
  • Extremely friendly for Linux newbies.
  • Boot up and run extraordinarily fast.
  • Have all the applications needed for daily use.
  • Will just work, no hassles.
  • Will breathe new life into old PCs
  • Load and run totally in RAM for diskless thin stations.
Here's a You tube video of the same. Just see the video for the features:

Mojave Experiment


This is yet another fascinating site which i discovered as i was browsing.. Wats so fascinating about it is the 3 D video cloud. Wondering wat it is??? Its nothing but a cluster of video in a 3 dimensional view. Well wat are the requirments your browser should have to view the site? Yes since its "Microsoft" you need a silverlight plugin installed in ur browser. Although the the same thing can be achieved in Flash:-).. Don worry just go to the site, if you don have silverlight plugin installed it will guide you to install.

The Mojave Experiment is an advertising campaign by Microsoft for the Windows Vista Operating System. The participants in the experiment were asked about their perceptions of Windows Vista (having never used it) and then were shown a ten minute demo of Microsoft's "next OS", codenamed "Mojave". After the experiment was over, it was revealed that "Mojave" was actually Windows Vista. Before the session, the average rating of Vista was 4.4 out of 10; after the session the average rating for the "Mojave" OS was 8.5 out of 10. The official goal of the Mojave Experiment is to get consumers to "decide for themselves" rather than accept the commonly held negative perceptions of Windows Vista, providing links to product demo videos and other product advertising. Microsoft says that it is slowly adding more video content to the Mojave Experiment website.

Google labs feature u must enable in gmail


Recently i was just going through the lab features for gmail. I have had a few lab features before. But I feel these two lab features is must enable if you have gmail account.  

Offline Gmail:
So even if you're offline, you can open your web browser, go to, and get to your mail just like you're used to.

Once you turn on this feature, Gmail uses
Gears to download a local cache of your mail. As long as you're connected to the network, that cache is synchronized with Gmail's servers. When you lose your connection, Gmail automatically switches to offline mode, and uses the data stored on your computer's hard drive instead of the information sent across the network. You can read messages, star and label them, and do all of the things you're used to doing while reading your webmail online. Any messages you send while offline will be placed in your outbox and automatically sent the next time Gmail detects a connection. And if you're on an unreliable or slow connection (like when you're "borrowing" your neighbor's wireless), you can choose to use "flaky connection mode," which is somewhere in between: it uses the local cache as if you were disconnected, but still synchronizes your mail with the server in the background. 
Isn't this really great.It is according to me..
So how to enable:
1.Click settings,then select the labs tab.
2.Then enable the offline gmail feature and save the settings.
3.Now you will find a link on top right side of the gmail window named offline gmail.
4. Click the link and follow the instructions.

Search people


There are various reasons why you might need to search for people, you may need to find a lost relative, an old flame, a classmate or a business contact - but if you are using a search engine such as Google or Yahoo to search for people, you have probably realized by now that it might work in some cases but in most cases it won't.

How come the best search engines fail so miserably when it comes to people search? The answer lies in a little known but very important part of the web called "deep web".
Also known as "invisible web", the term "deep web" refers to a vast repository of underlying content, such as documents in online databases that general-purpose web crawlers cannot reach. 
Pipl's query-engine helps you find deep web pages that cannot be found on regular search engines.

This is actually a cool idea.. who knows one day you might need this to search your old crush:-) or ur best friend who knows:-)
