One of my advisors is considering transitioning towards Julia from a traditional HPC background using C++ and Python. After a couple days playing around, he seems quite impressed by the flexibility of Julia’s type system. But, he hasn’t done any “serious numerical work” (his words), and he is wonder…

[image] Amval: Letting PyCall install packages has resulted on some unreproducible builds for me. Brief aside: you might want to look into PythonCall.jl , which gives you more control over your Conda environment.

Can’t generate small libraries to be used in production code (Integrated into C / C++ like I can do with MATLAB Coder). The design of the data structure in Julia’s image processing eco system. In my opinion it causes performance degradation and it is not intuitive. Once (1) will be achievable I wi…

This is just an idea (might be a completely stupid one). Just would like to have the view of a more experienced developer. I might be wrong but the C language is made of ~32 key words. How difficult would it be to give Julia the ability to compile binary from these equivalent 32 julia key words? O…

It’s not so much about the number of keywords but about garbage collection, dynamic code generation, and other things requiring runtime support. For sufficiently restricted subsets of Julia it is already possible (but not very polished) to do static compilation to small binaries. See e.g. Successful…

[image] GunnarFarneback: possible (but not very polished) It and StaticTools.jl is getting better, e.g. with adding Bumper.jl as a dependency for fewer memory-handling limitations. I think it might be very usable for many situations already if you can live with the stated limitations. One of …

Coming back to the original question: What I don’t like about the Julia ecosystem is the lack of stability of key packages: Both StaticArrays and Sundials were braking my code twice each in the last years when there was a minor update of the package version number. And Makie has braking changes all …

[image] ufechner7: Both StaticArrays and Sundials were braking my code twice each in the last years when there was a minor update of the package version number. Since the wrapper’s inception around 2014 and all of the things written about it, it has been noted that Sundials.jl only works with…

[image] ChrisRackauckas: Now change your code to Vector{Float64} if you want to be calling a C library to mutate that object. I tried that in the past and it caused a 10x slowdown of my code.

@adamslc , I am curious. Did your advisor transition to Julia at the end? In either case what was the reasons (pro/cons)?
