Here’s my attempt at creating a useful Python script: a static site generator that converts a folder of Markdown files into HTML. This project uses Python 3.12, uv for managing external dependencies, and supports either TOML or YAML front matter. We'll rely on mistletoe for Markdown conversion and jinja2 for HTML templating.
The script makes use of the following:

python: how to check if a line is an empty line - Stack Overflow
If you want to ignore lines with only whitespace:
if line.strip():
... do something
The empty string is a False value.
Or if you really want only empty lines:
if line in ['\n', '\r\n']:
... do something

Search for executable files using find command
answered by GreenGiant - Stack Overflow
On GNU versions of find you can use -executable:
find . -type f -executable -print
For BSD (and MacOS) versions of find, you can use -perm with + and an octal mask:
find . -type f -perm +111 -print
In this context "+" means "any of these bits are set" and 111 is the execute bits. Note that this is not identical to the -executable predicate in GNU find. In particular, -executable tests that the file can be executed by the current user, while -perm +111 just tests if any execute permissions are set.
Create a new user who is a member of the same groups as the current user.
$ groups
users lp wheel dialout video audio render docker autologin
$ printf "%s\n" $(groups) | sort
audio
autologin
dialout
docker
lp
render
users
video
wheel
tr '\n' ',' translates the newlines into commas, converting the list of groups into a comma-separated string
sed 's/.$//' uses sed (stream editor) to remove the last character (which will be the trailing comma from the previous step)
$ printf "%s\n" $(groups) | sort | tr '\n' ',' | sed 's/.$//'
audio,autologin,dialout,docker,lp,render,video,wheel
$ my_groups=$(printf "%s\n" $(groups) | sort | tr '\n' ',' | sed 's/.$//')
$ sudo useradd \
--comment "Hullo" \
--gid sudo \
--groups $my_groups \
--create-home \
--no-user-group \
newuser
# using short options
$ sudo useradd -g users -G $groups -m -N newuser

CORDIC is an algorithm for computing trig functions like sin, cos, tan etc on low powered hardware, without an FPU (i.e. no floating point) or expensive lookup tables. In fact, it reduces these complex functions to simple additions and bit shifts.

On April 5th, xkcd released Machine, the 15th annual April Fools project I’ve made with them.
It’s a game we’d been dreaming of for years: a giant rube goldberg machine builder in the style of the classic Incredible Machine games, made of a patchwork of machines created by individual xkcd readers
From Caveman to Chinaman - Cremieux Recueil
Briefly, seasonality is primarily dependent on three factors. The first is the Earth’s tilt, or obliquity, which determines how hemispheres will be tilted towards the Sun in summer and away in winter. The other two factors are lesser-known, but they are nevertheless important. They are the eccentricity of Earth’s orbit, which is how elliptical it is, and the precession, which is about whether the Earth’s closest approach to the Sun happens in the northern or southern hemisphere’s summer season

Creating Isometric RPG Game Backgrounds - using Stable Diffusion techniques to create 2D game environments
Great game development is actively harmed by this assumption. Pre-allocating resources at an early stage interrupts the exploratory iteration needed to find the fun in a game. A written plan that stretches months into the future is like a stake through the heart of a good game process. Instead of quickly pivoting to amplify a delightful opportunity found during play testing, you end up blindly barreling towards completion on a some ineffectual paper fantasy.

Development notes from xkcd's Gravity and Escape Speed #gamedev
Escape Seed is a large space exploration game created and drawn by Randall Munroe.
This was one of the most ambitious — and most delayed — April Fools comics we’ve ever shipped. The art, physics, story, game logic, and render performance all needed to work together to pull this off. We decided to take the time to get it right.
The game is a spiritual successor to last year’s Gravity space exploration comic. Our goal was to deepen the game with a bigger map and more orbital mechanics challenges to play with.

The meditative empathy of Susanna Clarke’s Piranesi - Vox by Constance Grady
There is something meditative about watching Piranesi live, the purity of his life and the kindness of it. And Piranesi’s kindness is possible in part because he lives in such communion with the House, which is his world. He respects the House and knows how to live within it, and in turn the House blesses him with its bounties.

Joan Didion: Only Disconnect Off Center: Essays by Barbara Grizzutti Harrison (1980).
I am disinclined to find endearing a chronicler of the 1960s who is beset by migraines that can be triggered by her decorator's having pleated instead of gathered her new diningroom curtains. These, and other assorted facts -- such as the fact that Didion chose to buy the dress Linda Kasabian wore at the Manson trial at I. Magnin in Beverly Hills -- put me more in mind of a neurasthenic Cher than of a writer who has been called America's finest woman prose stylist.

The World According to Peter Thiel - Erik Torenberg's Thoughts
His claim is that we've had this narrow cone of progress around the world of bits—around software & IT — but not atoms. The iPhones that distract us from our environment also distract us from how strangely old & unchanged our current environment is. If you were to be in any room in 1973, everything would look the same except for our phones. This explains his old Founders Fund tagline: “We wanted flying cars, instead we got 140 characters.”
Zooming out, people don’t understand how important economic growth is. It’s the only thing sustaining the planet. Without it, we go into a malthusian war. Indeed: The only way our societies have worked for at least 250 years is by economic growth. Parliamentary democracies are built on an ever-expanding pie that they can continue subdividing. Once the pie is no longer expanding, everything turns zero-sum.
Cyberdecks For High-Tech Low-Lifes - The Dork Web
The term “Cyberdeck” was first coined in Gibson’s 1984 literary masterpiece, Neuromancer. He rewrote parts of Neuromancer several times after the release of Ridley Scott’s Blade Runner. Blade Runner was based on Philip K. Dick’s 1968 novel Do Androids Dream of Electric Sheep. Scott, Dick, Brunner’s The Shockwave Rider, Goddard’s Alphaville and work by futurists such as Syd Mead and Moebius make the title of “father of Cyberpunk” hard to hang on Gibson alone. But he’s clearly a very important character in the development of Cyberpunk culture.
Just as Shakespeare brought in new words to describe new worlds, 1980s Gibson is Cyberpunk’s Great Bard. The Cyberdeck is just one of Gibson’s literary gifts. It’s the tool that lets Console Cowboys jack into the Matrix of Cyberspace and start hacking.
The anthropologist in an economist world - Altered States of Monetary Consciousness
Anthropology starts from the recognition that a person - in the first instance at least - cannot exist apart from a group. Put differently, anthropology assumes that a human network always precedes its individual members, and that care and reproduction precede any form of solo heroics. Human babies don’t survive long if they are left to fend for themselves, and - even if they miraculously survived without others - they would not be able to speak language, which would make all future social interaction, relationships and trade near-impossible.

Why You Should Use Component-Based Design in Unity
Let’s say that any weapon will have a component for damage, range, and projectiles (optional). Using Unity’s UI, you could create a weapon by dragging these components onto any GameObject and customizing the values of each one. Then, if the way projectiles are handled changes further into development, all you need to do is change one script, and all your weapons’ functionalities will be updated instead of just those defined at one level of a tree.
