[$] An alternate pattern-matching conditional for Elisp

Par : jake
1 mars 2024 à 16:30
One of the outcomes of the (extremely) lengthy discussion about using Common Lisp features in Emacs Lisp (Elisp), which we looked at back in November, was an effort to start removing some of those uses from Emacs. The rewrite of some of the Elisp in Emacs that uses the Common Lisp library (cl-lib) was started by Richard Stallman as a way to reduce the cognitive load needed for maintaining Emacs itself. Since then, he has broadened his efforts to simplify Elisp by adding a new pattern-matching conditional that would be a competitor to pcase, which is a longstanding macro that he finds overly complex.

[$] Vale: enforcing style guidelines for text

Par : jake
7 mars 2024 à 15:46
While programmers are used to having tools to check their code for stylistic problems, writers often limit automatic checks of their texts to spelling and, sometimes, grammar, because there are not a lot of options for further checking. If that is the case, Vale, an open-source, command-line tool to enforce editorial-style guidelines, would make a useful addition to their toolbox. The recent release of Vale 3.0 warrants a look at this versatile tool, which assists writers by identifying common errors and helping them maintain a consistent voice in their prose.

[$] "Real" anonymous functions for Python

Par : jake
19 mars 2024 à 21:18
There are a number of different language-enhancement ideas that crop up with some regularity in the Python community; many of them have been debated and shot down multiple times over the years. When one inevitably arises anew, it can sometimes be difficult to tamp it down, even if it is unlikely that the idea will go any further than the last N times it cropped up. A recent discussion about "real" anonymous functions follows a somewhat predictable path, but there are still reasons to participate in vetting these "new" ideas, despite the tiresome, repetitive nature of the exercise—examples of recurring feature ideas that were eventually adopted definitely exist.

Kernel prepatch 6.9-rc1

Par : jake
24 mars 2024 à 23:10
The 6.9-rc1 kernel prepatch is out for testing. Linus Torvalds described some rather large updates to the core kernel code that are coming for 6.9:
The timer subsystem had a fairly big rewrite, to have per-cpu timer wheels to improve performance of timers, which can be a big deal particularly for networking. The other fairly notable core update is to the workqueue subsystem, where one notable addition is for BH workqueue support. That's notable mainly because it means we finally have a way away from tasklets. The tasklet interface has basically been deprecated for a long while, but we've never really had any good alternatives (with threaded interrupt handlers being one suggested use-case, but not realistic in many cases).

[$] Book review: Practical Julia

Par : jake
10 avril 2024 à 14:31
A recent book by LWN guest author Lee Phillips provides a nice introduction to the Julia programming language. Practical Julia does more than that, however. As its subtitle ("A Hands-On Introduction for Scientific Minds") implies, the book focuses on bringing Julia to scientists, rather than programmers, which gives it something of a different feel from most other books of this sort.
