dex is a small and easy to use text editor:

LIOS (Linux Intelligent OCR Solution) is a one-stop OCR solution. It interfaces with a scanner, camera, PDF or image file, runs an OCR using the Tesseract or Cuneiform OCR engines, and saves the text in multiple formats, including reading it aloud in a robot voice. It sounded good, and there's a .deb package (there's also rpm packages), so I installed easily it in my Mint 17.1 by clicking on the downloaded package.

The OCR engine worked fine on whatever I threw at it with few errors, except for a 30 year old dot matrix print. Unfortunately, the program itself tends to be a "work in progress"; I haven't been able to export to PDF or text, except by highlighting text and cut-and-paste. Some of the other buttons will simply crash it.

The version I tried, 1.9.2, was released December 8, 2014, and version 2 will be releaased "soon", so this bears watching because it shows promise.

Thanks a lot for this list of Linux software.
Yesterday, using probably the wrong application, I was taking hours to sync two folders, then after reading here I learned about FreeFileSync, that finished the job in a few minutes, awesome.

By the way, I see that Truecrypt is still listed, with a link pointing to http://www[dot]truecrypt[dot]org/downloads [Mod: bad link obfuscated], which is currently considered suspicious. Looking for alternatives, so far I tried tcplay, not very user friendly being text only, but it works well with Truecrypt archives.

Welcome your comment Need3. TrueCrypt has now been delisted and replaced with AES Crypt. Give it a try and see how it goes.
