Erlang is a fast growing language and is used in many key applications. Being concurrent and fast..it is used in many applications where multiple service are required simultaneously.  It can be installed on linux via it package  or  simply from the terminal using : sudo apt-get install erlang I did using the source file from the erlang site. The following steps made me complete the installation: 1>download the tar file. 2> cd to the folder and unzip it. 3> go the unzipped folder. 4> Now, Erlang needs some other files to fully complete installations and generate documentations.   So the following steps needs to be done: sudo apt­-get install fop  sudo apt­-get install libncurses-5­-dev sudo apt­-get install openjdk­6­-jdk sudo apt­-get install unixodbc-­dev sudo apt­-get install g++ sudo apt­-get install libssl­-dev Still, Erlang requires wx libraries so we will do the following: sudo apt­-get install libwxbase2.8 sudo apt­-ge...

I had been using Ubuntu for quite a long time. Sometimes, problems arise as such like:  Windows cannot boot. or Ubuntu cannot boot. Solving this problem is easy: however it requires you to have: Internet connection. Ubuntu live cd or bootable pendrive. Now lets go through how we could solve this using a software: Boot from the pendrive or cd. Use the Try Ubuntu mode on first page. Connect to the net Open the terminal using ctrl+alt+t and do the following steps: sudo add-apt-repository ppa:yannubuntu/boot-repair sudo apt-get update sudo apt-get install -y boot-repair && (boot-repair &) Now a window will pop up after installation and it will give you the options. Choose whichever is appropriate and it will solve the problem. It also provides link to the error log file from where you can know more of the problem or ask the community about it. .......So don't worry next time...just do the steps listed above...If it does not solve ...leave a com...

If it was windows, it would be much easier ...for we have the universal USB installer. In Linux, we can't use that: however, we need not worry, guys have done a great job by creating a much easier tool to do the work. The tool is called gparted. It is a nice GUI tool to do our work. So lets see how we shall do it. >Open the terminal . >Now type: sudo apt-get install gparted ......This will install the tool ...well and good if you had it from before. >Now type: sudo apt-get install-3g ( gparted installed this as default for me...just see if it did for you). >Now open the tool via: System>Administration>Gparted Partition Tool >Now you are almost done....Click the File and choose the drive for the particular USB. >Right click on the drive when it is enlisted. See Manage Flag menu and click to enable boot. >Now go to Partition menu at the top panel and format the drive as ntfs . This will keep the work as pending operation ...click the cor...

Well I was just wondering how could I see the difference between two files in windows. Searching the net, I saw some softwares  that would do the job for me..But I wanted simple and fast not so sophisticated ... I found out we could do using a simple tool...fc..from the DOS prompt. FC is a command to view the difference of two files or set of files.. So the steps are: 1> go the directory where the files are.. 2>type  fc first-filename second-filename ....and there you go..You will get the result each different section divided by line of stars.. ...Its simple ...right?? I love it....The following explains the full usage method ------------------------------------------------------------------------------------------- Syntax: FC [d:][path]filename [d:][path]filename [/A][/C][/L][/Lb n] [/N][/T][/W][/(number)] for binary comparisons FC [d:][path]filename [d:][path]filename [/B][/number]  FC reports differences between the two files you specify. FC firs...

I have been using Linux on my PC using dual boot. This time I was using Ubuntu 11.10 ultimate edition.  As like many windows users ..I have been tempted my Mac-OS..and I have been using Mac theme for my PC too.. Recently I got too ambitious and I went on to install Macbuntu theme for my Linux ...(I thought I could be satisfied than I did on my windows)...Lo....During installation ...It got too complex...many downloads...and that too ...unverified..... After it was half way through ..the system tray could be seen...but it was not functioning at all... .....It was going too frustrating ...so I did a force shut down...(It was the last time I could see my GUI ...)...After this, I could never go back to the gui...All it was left was the tty..(and what much could we do in there..??).. I am careful now..I won't install any theme again...  

Well, we all know what and how JQuery has revolutionized the UI design and development of websites and web applications. Given its robustness for browser support, familiar syntax ,built-in animations and  not impact content gives it immense credibility and avenues for use in many great applications.. In its development novice developers sometimes makes the mistake of linking the lib from their own local site..However this is wrong ..which I can say confidently at least for the case of deployment of your app. The reason is: Using Cloud Scripts Keeps Your Pages Fast Linking to script libraries such as jQuery from an internet location  (such as http:/ /code.jquery.com/jquery-1.5.2.min.js in the HTML here) is a way of using a content  delivery network (CDN). When many developers link to the same location for a script, that script is more likely to be cached by your readers and load more quickly. Also, your browser may have a limit of as few as two connections to...

Well..It has been almost fascinating to try the new IntelliJ IDEA  based android IDE on my windows machine. It has been not been working since I installed it. I followed all the Stackoverflow and other blogs....regarding my problem... My problem was:  >I was using JDK 1.6.21...which probably was too old for the studio to get up with. >I did not add the JDK_HOME... ............I downloaded the new latest version of JDK and finally got the nice new thing running.. So,,update your system and don't forget to add the JDK _HOME directory to the system path....Its gonna be all ok then.. way to goo...                

Lets talk about some starting points of the mongoDB.. First..installation is easy as easiest: >Just go to the Mongo site and download the whichever package is needed for your system. Though it is recommended to work with th 64 bit version for production ..fear not you can do with any package that suits your system..remember...the version with the even no. in the middle means the stable release for the time. > Now extract the compressed filed and create a folder in a location of your choice. In the uncompressed folder..there will be bin folder..copy all its content to the folder you just created...And there it is the starting point for working on  mongodb. > When you have done all the above ...just open the command shell and go to the directory and type mongod...the mongo shell daemon. and it will start the mongo server. > You can type db( It is the command which you will use in every operation for it starting point for every command). This will print test...whi...

I just signed up for 10gen free class on MongoDB...and wow..its so easy and interesting to follow. I wondered what was all this buzz about NoSQL...but seeing it and coding it on my own has really made me believe that it is going to grow larger and more effective over the years to come. One thing that sets this new trend apart from others is its ability integrate easily with the client code: It can be just accessed from the code using the OOP approach that we are all accustomed to( I mean if you had been programming!).. Its schemaless ..meaning it does away with all those CRUD statements that we all use for RDBMS..though it has an adequate means of addressing all of that through a simple syntax and various APIs it provide for the same. One thing that it is critical about is the lack of: >Transactions >and Joins Still it has enough for all the uses it is meant for..where you would really have to do a big maintenance of bank accounts spanning over many countries...say in...

Last saturday, I went for the movie of the year: The Great Gatsby. It was such a nice movie...Leonardo and Tobey has done a tremendous acting together. The struggle of a man  trying to reconquer his love..."trying to change the past for his present"... I really love this movie..for it portrays a man trying all his ways to get his love and doing everything for the sake of his love.. The movie also portrays a materialistic mindset of the woman he loves who fails to appreciate his love and reciprocate or say understand whats beyond the truth and what odds her lover has taken for her. All and all ..It was a nice one...definitely worth watching

I have always been a firefox fan...right from the start...It always kept me wondering what makes this good piece of software work so well until I downloaded the source code and built it on my own.. I required the following: 1> Visual Studia 2010 2> Directx 3> Msys 4> Windows SDK You can download the source code from the mozilla website..Once you are done with that .. You can get all the detatils from the website on how to build the code . I had a simple problem...the Python path problem.. I had installed Python earlier and the build tool uses the Python embedded in the Msys... Once I removed the original Python path from my environment variables and replaced with that of the Msys ..It was all done.. The final part of build process gives you a firefox nightly .although it takes about 4 hours in my core 2 duo machine...Its such a neat and nice ..you would love it.. Thanks to the firefox team ...and all the supporters :)) 

I have just recovered from the usual blue screen problem with my laptop. I just thought it was going to be an "All Over Thing" for my hard drive...So I went to hp repair store-(www.laptopstore.in) ...man..they are stupid peoples ...commercials...having no knowledge nor commitment to solve problems. I came back ...and did these simple things . >Sanitized my hard drive through BIOS screen.. >Self tested the hard drive...aha...now it was working for me ...(probably those guys don't know about). Then I reinstalled my OS both Windows and Linux..as I usually do.. Now Its working..all fine...only thing I miss are those files I lost... I saved me huge..Those guys had told me to change my hard drive ... Thank God...I didn't .. Always test hard drive for error constantly and keep up the anti virus.... Adieu..

I installed Google Chrome today. Its easy, I just followed the following steps: 1> Download the .rpm package from the google chrome site. 2> Once that is done ...cd to the directory where it is located. 3> Now, type: sudo dpkg -i google_chrome.rpm( replace google_chrome with the actual file name) 4> It may not be done...due to lack of certain files...so do the following:     type: sudo apt-get install -f 5> There you go...you can get the chrome via Unity...so launch it and do the nice works.. /> Cheers...

I had a problem in Ubuntu of not being able to install a software. It gave me the following errors: E: Encountered a section with no Package: header E: Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_natty_main_binary-i386_Packages E: The package lists or status file could not be parsed or opened.   or like this one:   E: Malformed Description-md5 line; includes invalid character 'fc1f7600accbcc"07ef9954ba3306c14' E: The package lists or status file could not be parsed or opened But it was an easy problem to solve: The reasons for the problem arise from failed update attempt or may be when you try mess around with /var/lib/dpkg/status     Or may be you have too many sources in your repo,,,,that could also be a problem. To solve this is simple,,just do the following steps:   1> Open the terminal with ctrl+alt+t; 2> Type: sudo rm /var/lib/apt/lists/* -vf  3> Now type: sudo apt-get ...
