How can 'more' take 100 percent CPU?

The command was grep -i start */* | more

I recently tested MariaDB's plugin architecture to add functions for UUIDs. My friend Daniël took a look at the GitHub repo and left me some insightful comments, which I addressed in issue #1. If you know me, you may know that while my daughters are practicing basketball, I'm waiting coding… As I've always been very […]

I've been reading Drupal Core commits for more than 15 years. My workflow hasn't changed much over time. I subscribe to the Drupal Core commits RSS feed, and every morning, over coffee, I scan the new entries. For many of them, I click through to the issue on Drupal.org and read the summary and comments.

That workflow served me well for a long time. But when Drupal Starshot expanded my focus beyond Drupal Core to include Drupal CMS, Drupal Canvas, and the Drupal AI initiative, it became much harder to keep track of everything. All of this work happens in the open, but that doesn't make it easy to follow.

So I built a small tool I'm calling Drupal Digests. It watches the Drupal.org issue queues for Drupal Core, Drupal CMS, Drupal Canvas, and the Drupal AI initiative. When something noteworthy gets committed, it feeds the discussion and diff to AI, which writes me a summary: what changed, why it matters, and whether you need to do anything. You can see an example summary to get a feel for the format.

Each issue summary currently lives as its own Markdown file in a GitHub repository. Since I still like my morning coffee and RSS routine, I also generate RSS feeds that you can subscribe to in your favorite reader.

I built this to scratch my own itch, but realized it could help with something bigger. Staying informed is one of the hardest parts of contributing to a large Open Source project. These digests can help new contributors ramp up faster, help experienced module maintainers catch API changes, and make collaboration across the project easier.

I'm still tuning the prompts. Right now it costs me less than $2 a day in tokens, so I'm committed to running it for at least a year to see whether it's genuinely useful. If it proves valuable, I could imagine giving it a proper home, with search, filtering, and custom feeds.

For now, subscribe to a feed and tell me what you think.

Version 0.3.0 of the fnmatch-regex Rust crate is now available. The major new addition is the glob_to_regex_pattern function that only converts the glob pattern to a regular expression one without building a regular expression matcher. Two new features - regex and std - are also added, both enabled by default.

For more information, see the changelog at the homepage.

If you have a unary function F, you can compose it with function G, H = F ∘ G, which means H(x) = F(G(x)). Instead of running x through F directly, you run it through G first and then run the output of G through F.

If F is a binary function, then you either compose it with a unary function G on the left input: H = F ∘_left G, which means H(x, y) = F(G(x), y) or you compose it with a unary function G on the right input: H = F ∘_right G, which means H(x, y) = F(x, G(y)).

(binary-compose-left f g)  = (λ (x y) (f (g x) y))
(binary-compose-right f g) = (λ (x y) (f x (g y)))

We could extend this to trinary functions and beyond, but it is less common to want to compose functions with more than two inputs.

binary-compose-right comes in handy when combined with fold-left. This identity holds

 (fold-left (binary-compose-right f g) acc lst) <=>
   (fold-left f acc (map g lst))

but the right-hand side is less efficient because it requires an extra pass through the list to map g over it before folding. The left-hand side is more efficient because it composes g with f on the fly as it folds, so it only requires one pass through the list.

I released a hopefully inspiring gallery:

lisp-screenshots.org

We divide the showcase under the categories Music, Games, Graphics and CAD, Science and industry, Web applications, Editors and Utilities.

Of course:

"Please don't assume Lisp is only useful for...

thank you ;)

For more example of companies using CL in production, see this list (contributions welcome, of course).

Don't hesitate to share a screenshot of your app! It can be closed source and yourself as the sole user, as long as it as some sort of a GUI, and you use it. Historical success stories are for another collection.

The criteria are:

• built in Common Lisp
• with some sort of a graphical interface
• targeted at end users
• a clear reference, anywhere on the web, by email to me or simply as a comment here, that it is built in CL.

Details:

• it can be web applications whose server side is CL, even if the JS/HTML is classical web tech.
• no CLI interfaces. A readline app is OK but hey, we can do better.
• it can be closed-source or open-source, commercial, research or a personal software
• regarding "end users": I don't see how to include a tool like CEPL, but I did include a screen of LispWorks.
• bonus point if it is developed in a company (we want it on https://github.com/azzamsa/awesome-lisp-companies/), be it a commercial product or an internal tool.

You can reach us on GitHub discussions, by email at (reverse "gro.zliam@stohsneercs+leradniv") and in the comments.

Best,

Mark Friedman just released his Scheme-JS interpreter which is a Scheme with transparent JavaScript interoperability. See his blog post at furious ideas.

This interpreter apparently uses the techniques of lightweight stack inspection - Mark consulted me a bit about that hack works. I'm looking forward to seeing the vibe coded architecture.

Are you ready for another challenge? We're excited to host the second yearly edition of our treasure hunt at FOSDEM! Participants must solve five sequential challenges to uncover the final answer. Update: the treasure hunt has been successfully solved by multiple participants, and the main prizes have now been claimed. But the fun doesn't stop here. If you still manage to find the correct final answer and go to Infodesk K, you will receive a small consolation prize as a reward for your effort. If you're still looking for a challenge, the 2025 treasure hunt is still unsolved, so舰

If your non-geek partner and/or kids are joining you to FOSDEM, they may be interested in spending some time exploring Brussels while you attend the conference. Like previous years, FOSDEM is organising sightseeing tours.

With FOSDEM just a few days away, it is time for us to enlist your help. Every year, an enthusiastic band of volunteers make FOSDEM happen and make it a fun and safe place for all our attendees. We could not do this without you. This year we again need as many hands as possible, especially for heralding during the conference, during the buildup (starting Friday at noon) and teardown (Sunday evening). No need to worry about missing lunch at the weekend, food will be provided. Would you like to be part of the team that makes FOSDEM tick?舰
