Rubio orders return to Times New Roman font over ‘wasteful’ Calibri
US Secretary of State Marco Rubio has ordered diplomats to return to using Times New Roman font instead of Calibri, reversing a change made under the Biden administration. Rubio’s predecessor Antony Blinken had adopted Calibri in 2023, saying it was more accessible for people with visual disabilities. But Rubio said this was a “wasteful” diversity […]
When Would You Ever Want Bubblesort?
There are very few universal rules in software engineering, but there are are a lot of near-universal principles. Things like “prefer composition to inheritance” is near-universal. I love finding the rare situations where these principles don’t hold, like where you do want inheritance over composition. A similar near-universal principle is “don’t use bubblesort“. Some would […]
Getting a Gemini API key is an exercise in frustration
Last week, I started working on a new side-project. It’s a standard React app partly made up of run-of-the-mill CRUD views—a perfect fit for LLM-assisted programming. I reasoned that if I could get an LLM to quickly write the boring code for me, I’d have more time to focus on the interesting problems I wanted […]

Terrain Diffusion: A Diffusion-Based Successor to Perlin Noise
Abstract:For decades, procedural worlds have been built on procedural noise functions such as Perlin noise, which are fast and infinite, yet fundamentally limited in realism and large-scale coherence. We introduce Terrain Diffusion, an AI-era successor to Perlin noise that bridges the fidelity of diffusion models with the properties that made procedural noise indispensable: seamless infinite […]

Launch HN: InspectMind (YC W24) – AI agent for reviewing construction drawings
Hi HN, we’re Aakash and Shuangling of InspectMind (https://www.inspectmind.ai/), an AI “plan checker” that finds issues in construction drawings, details, and specs. Construction drawings quietly go out with lots of errors: dimension conflicts, co-ordination gaps, material mismatches, missing details and more. These errors turn into delays and hundreds of thousands of dollars of rework during […]
