Julia

FIRST-HAND READS

What people reported, in their own words. Every line links to where it was said.

• “The Julia code that processed the whole dataset and built the database took 5 hours, which made iterative development much more pleasant”

• “the core part (redefining Julia functions), already works in Julia Base”

• “My biggest problem with Julia is that they decided to use column-major indexing for multi-dimensional arrays (i.e. FORTRAN/MATLAB style). This makes interoperability with C/C++ and python numpy a real pain, since you can't do zero-copy array sharing between the two without one side being forced into strided-access. For that reason alone I haven't adopted it in any of my work-flows.”

• “Julia with some initial patience does deliver a better developer experience in this scenario than the equivalent Python experience for me partly because I do not need to play vectorizarion games, and I can do everything in one integrated environment”

• “tried installing julia on termux a few times with no success”

• “Julia tells the two operations (vector sum and outer sum) apart very elegantly: one is `S - T` and the other is `S .- T`: the dot here is very idiomatic and consistent with the rest of the syntax.”

• “Julia simply has become so much more productive and pleasant to work with”

• “julia is still clunky for these purposes! you can't even plot two things at the same time without it being weird and there's still a ton of textual noise when expressing linear algebra in it.”
