Despite this, some Old English pronouns like "he", "it", and "we" have survived more than 1,000 years of history and upheaval, almost intact.

Introduction to Nintendo DS Programming

https://www.patater.com/files/projects/manual/images/passme.png
The homebrew community allows individuals to create and run their own games on the Nintendo DS without needing official development contracts or equipment, using devices like passthroughs and NoPass devices to bypass copy protection. To get started, one should choose a Slot-1 device, such as the R4DS, M3 Real, or Cyclo DS Evolution, which supports DLDI and can run homebrew software from a microSD card.

How Pizza Tycoon simulated traffic on a 25 MHz CPU

https://pizzalegacy.nl/assets/blog/city_map2.png
The user reimplemented the traffic system from the 1994 DOS game Pizza Tycoon, which runs on a 25 MHz CPU, using a simple one-way road system and pairwise collision detection. The system uses a straightforward approach, with cars not needing pathfinding or physics, and collision detection being cheap due to early-exit logic and limited road directions.

Small Engines

https://scottlocklin.wordpress.com/wp-content/uploads/2026/02/energy-density.png?w=720
Building small, efficient heat engines is challenging due to the unfavorable surface area to volume ratio and difficulties in maintaining heat differences and flame propagation at small scales. Researchers are exploring alternative approaches, such as using new physics like sound waves and piezoelectric materials, to create small prime movers that can efficiently convert heat into motion.

Claude mixes up who said what and that's not OK

https://dwyer.co.za/static/claude-bug-1.png
Claude sometimes sends messages to itself and mistakenly attributes them to the user, leading to incorrect assumptions. This 'who said what' bug is distinct from hallucinations and permission issues, and seems to be a problem with the model's internal labelling rather than its behavior.

Code Is Cheap Now, and That Changes Everything

Kent Beck said 90% of his skills became worthless while 10% increased 1000x in value due to AI tools. This shift unlocks latent demand and makes software cheaper, but requires developers to focus on system definition and verification.

ML promises to be profoundly weird

The author discusses the limitations and potential risks of Large Language Models (LLMs), which are prone to confabulation, lying, and making up nonsense, and can be unpredictable and misleading. Despite their impressive capabilities, LLMs are far from human-equivalent intelligence and can only excel in specific, narrow tasks, making it difficult to predict their suitability for a given task.
