Need for phonetic editing has its roots in different keyboard layouts developed and used by different users and multiple fonts which in combination failed to produce unique easy to use compatible typing/editing solution. The problem is more in the area of software solutions being developed for different Indic Languages. Web based Direct editing or phonetic editing is an implementation which allows user to type in the context using phonetic key patterns across different keyboards, browsers and different Indic scripts.

What is gamabhana?

gamabhana is an open source implementation that uses purely client side java script to enable phonetics in editable html tags such as div (not editable in mozilla firefox) , iframe, input, textarea, document so that you can type in the context phonetically in the selected Indic script with transliteration capabilities that support unicode fonts with the help of  pre-designed gamabhana maps.

With gamabhana library and gamabhana phonetic maps you can:

  • Attach phonetics to editable html tags such as iframe and/or input (single line) and/or textarea and/or document.
  • Design your own transliteration maps for any language/script.
  • Achieve Unicode support across browsers, applications, platforms.
  • Type in the context phonetically ( direct input method) in IE ( V 5 above) and Firefox Mozilla.

गामाभाना is now available @ drupal.org

PXE : making your admins life easier

Need to setup a lab/office with 200+ computers, very tiring job but look if you have machines identical in configuration why are you installing each of them why not install one and replicate it to others this will save a lot of time, But how will i do this?????????? Its very very simple you can do a dd of the source to all destination but this would be even difficult and a bit geeky, hey dont worry we have a solution for it use PXE. 

Now what is this PXE??

Wikipedia "The Preboot eXecution Environment (PXE, also known as Pre-Execution Environment, or 'pixie') is an environment to boot computers using a network interface independently of available data storage devices (like hard disks) or installed operating systems."

But how does it help?? :)

there can be different situations of installation for eg u only need to install one operating system on a machine this can be easily dome by using an image which is already stored on PXE server as i call it. or u might have a whole list of OS and other softwares which are  required to be installed/configured on every machine in the environment now how do i achieve this. The solution is configure once machine with all the required softwares into it and replicate this using pxe. its very simple just setup a PXE server which provides a sender-receiver mechanism i.e which can make once machine as sender and others receiver once its done you can relax and have your whole environment setup within 30mins or so, time would very on various issues including Network and Disk Size.

But how to design a PXE Server??

I would not write a how to as its already available on Internet i just don't want to duplicate things so you can now move to http://udpcast.linux.lu (this is really a gr8 open-source project) or https://wiki.koeln.ccc.de/index.php/Ubuntu_PXE_Install and configure your own PXE server just for an hint u need to install the following on services 1) tftp-hpa 2) dhcp3-server (u can use another machine as a dhcp server as well) 3) netkit-inetd 4) You might need to recompile the kernel to suit your requirements in case of any problems you can write to me :) this PXE system has helped me a lot many times, i have configured one such system today which worked on fine so i strongly recommend this but use it on your own risk a single mistake can wipe out your entire data or do something which you have never expected so it on your own risk
