Re: [julia-users] High memory consumption with loops

I don't have any suggestions about the performance, but I do have a code correctness suggestion. It appears from your code snippet that you are using dictionaries called "effectiveness" and "resource_fines", and that the keys to these dictionaries are a mutable type. This can lead to subtle

Tim Holy, I am watching your keynote speech at JuliaCon 2016 where you mention the best optimization is not doing the computation at all. Domingos talks about that in his book, where an efficient kind of learning is by analogy, with no model at all, and how numerous scientific discoveries

Re: [julia-users] Differential Equations Package

This has already been done. As of last night we have JuliaDiffEq where we have moved Sundials and ODE. DifferentialEquations will follow soon, and I am talking with the owner of ODEInterface to see if that should go there as well (and if it should be expanded).

A bit. Sparse matrices with stored zeros were mostly an "I know what I'm doing" feature until recently. If you're familiar with the CSC data structure you can also call the low-level SparseMatrixCSC constructor directly: julia> SparseMatrixCSC(1, 1, [1,2], [1], [0]) 1x1 sparse matrix with 1

Whilst people do it successfully, it's probably a bad idea to have a git repo on Dropbox (corruption could occur if it gets modified from several machines). You'd have to clone it from the file system though: Pkg.clone("/path/to/drobox-folder/repo"). Cloning over https means that there needs to
