One area that I have always found lacking on Linux is a good Dictionary software. I have tired quite a few free and 
opensource dictionary software for linux, some very good, but non had the WOW factor to keep me using them again and again. Well that was until I stumbled (no pun intended) on Artha (yeah I know free software apps and their funny names 
)

Saturday, February 27th, 2010An easy way to Spilt or Merge PDF Files in Linux
Friday, April 17th, 2009I work as the IT guy of a school that runs free software on all our computers. So far majority of our computing needs has been met by free software. ( all of them if we exclude matlab and some freedom hating multimedia codecs.) One area that has been quite shaky is a good tool that can be used for merging different pdf files into one. There is a tool called pdftk but its command-line and while i don’t have a problem using it, its hardly the tool i want to recommend for our staffs and students, so when this morning i saw a dent on identi.ca about a tool called PDF-Shuffler which among other things provide an easy way to merge PDF files i decided to to Investigate.
PDF-Shuffler is a small python-gtk application, which helps the user to merge or split PDF documents. You can also rotate, crop and rearrange their pages using an interactive and intuitive graphical interface.
