How to install

  1. Install a user scripts extension for your browser:
  2. Install this user script: http://goo.gl/H3RKQA - ignore the "invalid header" error - it's because I'm using the RAW output from the gist, without using the revision (so that it stays current)
  3. ???

How to make Windows 7 USB flash install media from Linux?

How to make Windows 7 USB flash install media from Linux?

StackOverflow

  • Install ms-sys - if it is not in your repositories, get it here. Or alternatively, make sure lilo is installed (but do not run the liloconfig step on your local box if e.g. Grub is installed there!)
  • Check what device your USB media is assigned - here we will assume it is /dev/sdb. Delete all partitions, create a new one taking up all the space, set type to NTFS (7), and remember to set it bootable:
# cfdisk /dev/sdb
or fdisk /dev/sdb (partition type 7, and bootable flag)

Transliterating english to Kannada
<?php
/**
Trasliterate method takes 5 , seaparated english words and transliterates them into Kannada,
The result is an array of words in the same order. This uses Non public Google online transliteration API for this.
When you run this method give a 10ms seconds gap between each call to be on the safer side.
