He are some links to software I have made and that I find useful.
Software I Use
- Julia – easy to use like MATLAB, and runs fast like C. I have made (minor) contributions to several packages.
    
- JuliaLang – the git repo
 - GaussianProcesses.jl – simple GP toolbox
 - Mocha.jl – neural network toolbox (similar to caffe)
 - Graphs.jl – toolbox for building, visualizing, and creating graphs
 - LightGraphs.jl – another graphs toolbox, when you don’t need all of the fancy stuff
