Introduction to Julia for Pythonistas
summary
Claims Julia solves the two‑language problem by giving near‑C speed with high‑level syntax, demonstrates REPL workflows, arrays, broadcasting, and that slicing defaults to copies (use views to avoid copies). Shows concrete numbers: version 0.4.6 moving to 0.5, a claimed ~10× speedup on one port, 171 add methods counted, and an automatic forward autodiff via dual numbers in ~30 lines that composes with linear algebra and works. Notes easy C interop and PyCall availability.
