These are particular interesting to me (if I were a student, or not already more than full-time working using Julia), I'd jump on one of these two: https://github.com/JuliaLang/julialang.github.com/blob/master/gsoc/2015/index.md#project-simple-persistent-distributed-storage https://github.com/JuliaLang/julialang.github.com/blob/master/gsoc/2015/index.md#project-fast-bignums-in-julia
The second also ties in with my interest in have fast decimal numbers in Julia, both fixed size (32,64,128), and arbitrary like bignums.
