The story of debugging a mysterious Julia segfault.
Within private companies, it can be difficult to smoothly transition internal code into high quality open-source contributions. At JuliaCon 2020, industry Julia users came together to discuss how to maximize their impact in the Julia ecosystem.
GSoC & JSoC 2020 Wrap-Up.
Julia runs fast, but suffers from latency due to compilation. This post analyzes one source of excess compilation, tools for detecting and eliminating its causes, and the impact this effort has had on latency.
This year, 2,565 Julia users and developers participated in the second annual Julia User and Developer Survey.
Julia version 1.5 has been released, featuring many performance improvements and new capabilities.
R-devel-win.exe is an experimental installer of R, set up to download experimental binary builds of CRAN packages. It sets UTF-8 as the current default encoding on Windows (Windows 10 November 2019 release or newer). 92% of CRAN packages are sup[…]
Support for gradient fills, pattern fills, clipping paths and masks has been added to the R graphics engine (in the development version of R, which will probably become R version 4.1.0).
An R-level interface for these new features has been added[…]
The first release of Lua 5.4 is now ready
The Lua Workshop 2021 will be held in Freiburg, Germany.
UPDATE (2020-11-18): canClip = NA_LOGICAL has been replaced by deviceClip = TRUE
The R graphics engine performs some clipping of output regardless of whether the graphics device it is sending output to can perform clipping itself. For example, o[…]
Sometimes it is useful to test R on unusual platforms, even when the expected number of users is not large at the moment. It is better to be ready when a new platform arrives or becomes more widely used, it may be easier to find some bugs on one[…]

Julia 1.5 is gaining a cool new bug reporting capability, leveraging mozilla's rr project to automatically create fully-reproducible bug reports
R internally allows strings to be represented in the current native encoding, in UTF-8 and in Latin 1. When interacting with the operating system or external libraries, all these representations have to be converted to native encoding. On Linux […]
The symbol font When drawing text in R graphics, we can specify the font “family” to use, e.g., a generic family like "sans" or a specific family like "Helvetica", and we can specify the font “face” to use, e.g., plain, bold, or italic. […]
One of the main downsides to the ‘grid’ graphics package is that it is slow. And that makes some important packages that depend on ‘grid’, like ‘ggplot2’, slow. For example, the scatterplots shown below are roughly equivalent, but on[…]
Starting up a PSOCK cluster is not fast. In R 3.6 on just a few years old laptop with 8 logical cores, running Windows, it takes about 1.7s to start a cluster with 8 nodes:
library(parallel); system.time(cl <- makePSOCKcluster(8)) A good desi[…]
Since its inception, R has, at least by default, converted (character) strings to factors when creating data frames directly with data.frame() or as the result of using read.table() variants to read in tabular data. Quite likely, this will soon […]
Over the last couple of months, 212 young people have completed over 690 tasks using Julia as part of the Google Code-In program.

从事软件开发的行家里手们对版本发布流程与节奏如此了若指掌，以至于他们将其精髓内化（internalize）并以为人人都懂得这些“浅显的道理”。可是事实恰好相反，外行一眼望去如同雾里看花。所以为了整个Julia社区，乃至于其它编程语言社区，我觉得有必要将Julia的开发过程白纸黑字地写下来。在本文中，我将阐述...
