KSim
Developed to aid the research activity, its design includes an ad hoc language that makes it simple to build certain type of simulations. It includes a compiler to machine code, a submission engine and visualization tools.
Odexi CAS
This Computer Algebra System is a stub, which was developed mainly for practice with certain algorithms.
It is far from being complete, but it can do some staff and I have been using it from time to time
for very simple tasks. You can try it here using a guest account.
Login is 'guest', as for the password you will have to guess it but it is straightforward.
Please note that, as a guest, all your coding will be lost once your session expires.

Crawler
A gentle web crawler, that does not annoy site owners. It can be tuned towards breadth-first crawls, which renders the crawling very gentle to the target websites. It powers internal searches on a few, personal, websites.
DeryaSE
A research tool developed to explore the dynamics of infectious diseases. It can build and execute massive simulations of spread at the individual level on large computer clusters. Its key features include the possibility to explore geographic spread in high spatial resolution, easiness of implementation of epidemiological models, possibility to attach specific information to individuals, and a high level of control of the simulation.
