tmux is one of the most popular Terminal Multiplexer (never used it? If you’e a heavy terminal user, then probably you need it) . The latest release is v1.8.
Recently I wrote an article on managing multiple terminals with Terminator, tmux is a very similar program but I feel – tmux is more efficeint/faster, specially with vim (or any command line editor such as Emacs). So, whether you already use a similar program or not, you should try tmux.
Installing tmux on Ubuntu
sudo apt-get install tmux
Here is a screenshot (designing my personal blog with jekyll, I’ll launch in next few weeks) using tmux with vim editor.

There are lot of dictionary application for Ubuntu / Linux Mint but most of them works only online. A lot of people prefer to have offline dictionary – because they can use it without any internet connectivity or may be because they have a slow Internet connection (which may results in slower look-up).

Although, Goldendict has lots of features and many of them depends on Internet connectivity but you can easily install wordnet dictionary database to make it work offline.
Install Godendict on Ubuntu 12.04/12.10/ Linux Mint!

Tesseract is the best program for converting image to text, on Ubuntu/Linux. I’ve tried several OCR (Optical Character Recognition) applications but its accuracy is certainly higher than any other applications.
Tesseract is a simple and easy to use command line utility. It’s cross-platform application, and of course – it’s a free and open source software! You can supply various input formats and it can convert into 60+ languages.
Installing Tesseract in Ubuntu / Linux
sudo apt-get install tesseract-ocr
Further, you can install any language packages if required.
Now, before you start using Tesseract, you need to convert the files (png/jpg) to tif format (input format supported by tesseract). Use the following command (you may need to install imagemagick package) –
convert file_name.png out_file_name.tif
Now, you can try reading the content using Tesseract.
tesseract your_scanned_file.tif output_content
The results will be saved to output_content.txt file. If you want to OCR for other languages then pass it as the additional parameter, specified by
-l. (and of course, you would have to first install that language pack)
e.g For scanning images that contains Hindi, Sanskrit text, you can use this command :
tesseract your_scanned_page.tif output_content -l hin
