Links from Julia Land

Julia 0.3 Release Candidate 1 has quietly appeared on the nightly builds page; release notes in the very active GitHub repository - improvements to the REPL (tab conversion of ‘latex maths’ to unicode), and a lot of interesting linear algebra improvements.

The inaugural JuliaCon has been held, and the presentation slidedecks are already online:; videos are coming but the upload date has been pushed back as they are edited and transcribed.

On the Julia users email list, there was a link published to a very interesting essay on the history of programming languages:!topic/julia-users/T6f9hCkDW6g. It ends on a very pro-Julia note!

I’ve personally just been using Julia ‘for real’ in preparing some data for a publication (rather than just using iJulia as a glorified unicode-capable calculator for physical identities). Here I used Julia to calculate the partition function on the fly (by Monte Carlo integration) for an arbitrary torsional potential in a polymer, then form a tight binding Hamiltonian & evaluate the density of states extremely quickly with the Sturm sequence method. If I hadn’t discovered Julia, I would have been trying to do this with Python, and though totally feasible I’m not sure I would have got here. You are perpetually operating at the absolute limit of your cognitive capacity in scientific theory (and for me, I’m pretty limited); the more powerful the tools you have the more you can achieve, and Julia does indeed seem a very well geared ‘bicycle for the mind’ in scientific computing.
