And further imagine that you are required to pay Costco no matter if you shop there or not.

MELBOURNE (ANP/RTR) - Tennisster Coco Gauff wil graag dat niet alle emoties van teleurgestelde spelers worden uitgezonden en meer ruimte voor privémomenten bij de grote toernooien. Dat zei de Amerikaanse na haar uitschakeling in de kwartfinales van de Australian Open tegen de Oekraïense Elena Svitolina.

I haven't yet published my #Racket -based static site generator, but I have converted my site to use it. joeldueck.com/code/jdcom

Screenshot of the source code for a `site.rkt` Racket module written in `#lang camp/site`. The file consists of website configuration settings, such as authors, url, and page collections, in TOML format.

I updated my "is #guile fast?" page with the new r7rs #benchmarks data and anchored Guile and #Chez in the benchmarksgame:

#Scheme benchmarks: draketo.de/software/guile-fast
Compared to other languages: draketo.de/software/guile-fast

Chez is roughly factor 7 slower than C,
Guile roughly factor 18
(#Java 3.5, #SBCL 5, #Racket 12, #Ruby 60 and #Python 70)

Diagram of the slowdown of different programming languages, with Guile and Chez anchored it:

Today I went to a skin doctor in Czechia after 4 months (!!!) waiting after she gave me an appointment.

She violated a law in a way that is punished by a fine $0 - $90 909 by refusing to give me a paper with identifier of electronic prescription when I demanded it.

I think Czechia is so corrupt.

In Cambodia skin doctor waiting time is maybe 7-10 days not 120 days like in Czechia and they don't refuse to give me a paper with prescription.

Also in Cambodia when old ointment runs out it's possible to buy new one without prescription. In Czechia I can't and have to wait 4 months! And she told me there is some other doctor who is faster, I googled it and it didn't exist!

Due to this waiting 4 months my eczema screwed up big time, increased to an area about 20 times the size before the ointment ran out!

I feel

e x t r e m e l y s t r o n g c o n t e m p t

towards Czech regime when I have such experience with the so called "healthcare system" here (IMO more like making-sure-people-stay-sick-by-depriving-them-of-healthcare-to-extract-extortion-racket-money-from-them-by-denying-them-the-possibility-to-buy-medication-they-need-to-take-care-of-their-health-themselves system)

@nixfreak @izder456 currenty I'm using XFCE, but I also run SwayWM with wayland on #OpenBSD sometimes. Lisp wise, I've always got #racket to hand for experimentation, scripting, presentations, etc. Sometimes I have Common Lisp around (sbcl) for things. Elisp, is of course there, #Emacs is still a big part of how I use my computers in all scenarios.

I just completed "Gift Shop" - Day 2 - Advent of Code 2025 #AdventOfCode adventofcode.com/2025/day/2

I did this part in Racket. Oh, Racket, you are so lovely.

Build times in #idris are frequently fairly long, and I can certainly understand why. But, does anyone have experience (or better benchmarks) that would indicate whether I should use #ShezScheme or #Racket as the backend for low compilation times?

I've got both easily available through the Debian repositories and both seem to work, but I'm using them on such different systems that my experience isn't enough to compare.backends.

@lxsameer@mastodon.social i am no lisper, but I find this example interesting in #racket

> (+ x 1)

#<procedure:+>

> SMathML is a way to write mathematics on the web. More precisely, it is an embedded DSL in Racket for expressing MathML and HTML. By SMathML one can build high-level abstractions, such as transformations on XML.

Taking some Xmas afternoon time to share something I’ve been crafting over the holiday. I’ve added a #Typst renderer to Punct, so you can write stuff in #Markdown + #Racket code and easily dual-publish to HTML and PDF from the same sources. joeldueck.com/what-about/punct 🧵

Annotated screenshot collage showing a “Punct” publishing workflow: a Racket/Markdown source file (“bones.poem.rkt”) in VS Code compiles to a format-independent AST (shown in a DrRacket/REPL window), then renders to Typst or HTML, producing matching outputs—a web page on the left labeled “HTML” and a PDF preview on the right labeled “PDF.” Numbered red callouts trace the steps (source → AST → render → run commands → results) and note that you can insert rendered documents into templates to generate web pages and books from the same source.

The image is a black-and-white photograph of a person playing tennis. The individual is in the middle of a forehand swing, with their right arm extended forward and their left arm bent behind them, holding the tennis racket. The person is wearing a long dress with a belt around the waist and white shoes, which are typical attire for tennis players from the early 20th century. The background appears to be a tennis court, with visible white lines marking the boundaries of the court. The lighting in the image is dim, suggesting that the photograph may have been taken in a low-light environment or with a slow shutter speed. The overall tone of the image is nostalgic, capturing a moment from a bygone era of tennis.
