BTW, most of the machines from the book have been featured on @adriansdigitalbasement.com's YT channel. Just a few weeks ago he released a video on the Archimedes:

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

I just heard a new term I'm going to be using in the future: Slopsplaining:

When someone who doesn't know anything about a topic offers up unsolicited AI generated slop 'advice' to others.

It's Patch Tuesday and ASP.NET Core has a doozy, with a CVSS score of 9.9, our highest ever. Let's examine why.

The bug enables http request smuggling, which on its own for ASP.NET Core would be nowhere near that high, but that's not how we rate things...

Yeah, I think it's typically one or the other. There's one repeater in my area (though too far for me to reach) that's configured for DMR+ on one TS and BM on the other, but that really doesn't seem to be common.

Dennis "D.C." Dietrich @dcdietrich.bsky.social · Sep 29

BTW, lemme know if I need to get onto BrandMeister. Until now all my DMR QSOs have been on DMR+.

Very good. Gotta update the DMR ID DB on my radios. Are you going to use OpenGD77 (at least on one of them)?

Dennis "D.C." Dietrich @dcdietrich.bsky.social · Sep 28

Hey @guy.dev! Very delighted indeed! What radios did you buy? Are you going to hit a local repeater or did you also get a hotspot?

Tempting. Seriously considering getting one: "Looking at the internals, the Pi 500+ has a 2.4GHz quad-core Arm Cortex-A76 CPU and 16GB of LPDDR4X-4267 SDRAM inside it. It also has a 256GB M.2 SSD [...]."

"In this book I will not attempt to answer the question of whether or not computers can be programmed to think. I sometimes ask people if people can think. Human intelligence may also be an illusion.”

-Timothy J. O'Malley

A book cover that says "ARTIFICIAL INTELLIGENCE PROJECTS FOR THE COMMODORE 64." Author: Timothy J. O'Malley
On the cover is an abstract picture of a human head with lines going through it to represent AI, and below the head is a Commodore 64 keyboard.

Computer scientists believe that soon every home will be able to have their own artificial intelligence machine on their own desktops (Source.)

A book that reads in block sans serif font, "ARTIFICIAL INTELLIGENCE PROJECTS FOR THE COMMODORE 64." The text is red, switching to gold for the words 'Commodore 64'. Cover bottom, a Commodore 64 - a light brown all-in-one microcomputer with dark brown keys - appears. In the center, a gold PCB in the shape of a human head radiates gold wires in the way wires might radiate from a chip, creating the silhouette of a head; in the center and neck of the head-shaped PCB, chips appear.
