State of Julia | Jeff Bezanson & Stefan Karpinski | JuliaCon 2020

Abstract: We take stock of Julia and its ecosystem. The releases since 1.0 have been less major and non-breaking—which has been a relief—but nevertheless, a significant number of major new functionality has been added. We'll highlight some of the biggest developments in the language (can anyone say "multithreading"?), infrastructure (BB, Pkg3, Artifacts), and ecosystem (the Dataverse, DiffEqs, differentiable programming) and beyond. And finally, we look ahead to Julia 2.0. Contents 00:00 Welcome! 00:15 Introduction by Stefan Karpinski 00:58 Multithreading 02:39 Latency: "I think about it every day, I worry about it every day." 04:54 Debugger for Julia 07:50 Pkg3, Julia package manager 10:51 Package ecosystem 15:21 JuliaMono, Julia typeface 16:16 Where are we now: v1.5 16:48 Multithreading in v1.5 17:49 Why is Julia sometimes slower than C++? 18:11 Heap allocation in Julia 19:49 What are watershed moments in the development of language? 20:32 Scope of variable 24:25 Pkg protocol 26:42 PkgServer.jl package and servers infrastructure 27:46 Latency still is a problem 28:30 Tasks and threads system 29:47 Compiler: the next generation 31:32 Pkg features coming with Julia v1.6 33:11 The king is dead: Julia 1.0 will stop being LTS version 33:54 Long live the king: Julia 1.6 will be the new LTS 35:37 Amazing progress & bright future 36:17 Thank you! 37:32 Q&A: Does the work plan for latency include working on tasks and threads? 38:14 Q&A: What is the best-case scenario for Julia's compiler latency?
