Mathpump is a simplistic remote collaboration tool. It could be useful for those researchers who tend to think by drawing pictures (e.g. theoretical physics). Bob uses Inkscape to draw a picture, which is incrementally transmitted to the Alice's computer so she can look at it. She answers by drawing her own picture, which is transmitted to Bob. Transmission happens every time the SVG file is saved. The transmission is incremental; what is actually transmitted is the difference between the old version of the SVG file and the new one.
This program is especially useful when the main difference between the two LaTeX files is in permutation of sections, moved equations, etc. Given 2 LaTeX files, it prepares 2 annotated LaTeX files showing which equations of the 1st file are identical, or close, or similar, to which equations of the 2nd file. It does the same with the pieces of text. It also saves the snippets of text and equations from each text into separate files in 2 new folders, allowing the user to see the difference using a diff program.
IDLE is an academic learning management system. It is an interactive learning environment. It was first developed to improve the learning environment of database courses. The main purpose of IDLE is to make the learning environment as interactive as possible to benefit both student and teacher. Teachers can use IDLE to provide exercises, guidelines for the exercises, necessary materials for that particular course, and so on. Students can go through the exercises and their guidelines and upload their answers in this system.
