Ask HN: 80s electronics book club; anyone remember this illustrator?

news.ycombinator.com Unknown 2026-03-10 21:46:18

In the early 80's in the US, a popular DIY electronics magazine had a book of the month club that I loved. Most were small and leather bound hardback with topics like: make your own hydrophone; augmented reality (required a full room and a boom arm, sadly); an LCD model rocket launcher ignition; computer vision; lots and lots of robots. One book I remember (large, softcover, yellow cover) featured black and white, pen and ink illustrations of fantastically complex robots and machines. One that

Entropy of a Mixture

Creating fair dice from random objects

What if you could make your dice any shape at all—not just boxes and polyhedra, but dragons or other game-relevant shapes? Most people are familiar with conventional cubical six-sided dice, but there are also polyhedral versions like the 20-sided dice used in ancient Rome and to play Dungeons and Dragons. Researchers have figured out how to design dice with even more exotic shapes, like a kitten, a dragon, or an armadillo. And they are "fair" dice: Experiments with 3D-printed versions produced

End of an Era

news.ycombinator.com Chris Crawford 2026-03-13 14:17:11

I recall saying to one of my colleagues at Atari way back in 1982 that I wanted to make a game that would be genuine art. A year later I built a game that was my first experiment in that direction: Gossip. It was a ridiculously simple game in which a player attempted to win favor in a group by calling people and telling them how much you liked or disliked some third party. The underlying concept was that “people like people who like people they like.” For some reason, many players had problems a

The hidden JTAG in a Qualcomm/Snapdragon device’s USB port

news.ycombinator.com Unknown 2026-03-13 13:34:27

Back in February of this year, Qualcomm quietly published the source code for interacting with EUD. This is perhaps one of the most exciting things they’ve done lately - especially if you spend a lot of time debugging the kernel or U-Boot - let’s talk about it. EUD stands for Embedded USB Debug: essentially, this is a debug interface built right into almost every Qualcomm SoC since ~2018. Internally it hooks deep into the SoC, providing debug facilities for not just the CPUs but also the myriad

The New Skill in AI Is Not Prompting, It's Context Engineering

June 30, 2025 5 minute read Context Engineering is new term gaining traction in the AI world. The conversation is shifting from "prompt engineering" to a broader, more powerful concept: Context Engineering. Tobi Lutke describes it as "the art of providing all the context for the task to be plausibly solvable by the LLM.” and he is right.

This Survey Asked Neuroscientists If Memories Can Be Extracted From the Dead. Here’s What They Said

gizmodo.com Natalia Mesa 2026-03-13 16:20:54

The allure and terror of transferring your consciousness to a computer has long been fodder for cyberpunk novels and billionaire-backed immortality startups. But a substantial chunk of neuroscientists think it might be possible to extract memories from a preserved brain and store those memories inside a computer, according to a new study. The study, published in the journal PLOS One, suggests that most neuroscientists believe that memory has a physical basis and, on average, give a 40% probabil

A boomerang carved from a mammoth tusk is one of the oldest in the world, and it may be even older than archaeologists originally thought, according to a recent round of radiocarbon dating. Archaeologists unearthed the mammoth-tusk boomerang in Poland’s Oblazowa Cave in the 1990s, and they originally dated it to around 18,000 years old, which made it one of the world’s oldest intact boomerangs.
