A few months ago, demoscene was inscribed in the national intangible cultural heritage in France. #AtariST computers appear often in this French video youtu.be/_skK8JU1CPQ #atari #demoscene

What can robotics learn from watch design?
- Hundreds of parts packed into a coin-sized case,
- keeping time within ±20 seconds daily
- enduring decades of use
Mechanical design at its most optimal.
Let's explore the mechanisms that make watches tick ⬇️

I recently had the honor of interviewing Zen’s chief architect Mike Clark! I tried to fit in as many microarchitecture questions as I could, including x64 vs ARM ISA power efficiency, 4k vs larger page sizes, 64-byte cache lines, scatter/gather and more:

We JUST solved a hard open math problem— the moving sofa problem!
"What is the area of the largest shape that can be manuevered through an L corner of width 1?"
On Dec 2, 2024, Korean Jineon Baek proved the answer is the 18 curve section Gerver's sofa with area 2.2195..!

Have you ever wondered what ‘occupancy’ means? Or how to identify occupancy-limited workloads?
Our new post gives an overview of occupancy, how to measure it with tools, and ways to improve it.

How 6502 Illegal Opcodes Really Work
The 6502 is known for its illegal opcodes. Out of 256 possible opcodes, only 151 are defined by the architecture.
This article explains where the remaining 105 undefined opcodes come from:

The Intel 8086 processor (1978) started the x86 architecture still used today. This chip only had 40 pins, so the address pins needed to be reused for data or status. (The pins are connected to the pads around the edge.) It took some tricky circuitry to make this work. 🧵

This is absolutely insane. Any pattern in Conway's Game Of Life can be constructed by a starting pattern of just 15 gliders. Which pattern you build all depends on how far apart you space them out.

I am happy to say goodbye to all the plotly and other less beautiful and less functional alternatives. Great color theme as well. Thank you @iquilezles !
