perl-depends is a tool that roughly determines the modules a Perl program uses. Perl evaluates "use" commands at compile time and stores the loaded module information into the %INC variable. By examining the loaded modules and comparing them against the standard Perl modules, the external module dependencies can be roughly estimated.
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.
Apilator is a high-performance, self-contained clustered server for building data APIs over HTTP. Its components and algorithms have been carefully selected for high performance, and it is especially suitable for systems with a large number of low-activity clients, such as mobile or Web-based applications. It does not need an external application server, and features automated session cookies, automatically synchronised session storage across multiple instances, and unique dynamically adjusted session storage that gives you the flexibility to add or remove servers from the cluster without configuration or restarting.
