I spent the weekend teaching the new Cybersecurity merit badge to 30 eager scouts. My thoughts:

- Good overview of the technology without going too deep
- Kids already understand some of this a basic level thanks to living the technology
- Always a couple of advanced students!

Context Is Expensive When it comes to learning and understanding, facts are easy. If I ask you how many bits are in an IPv4 address it's a single answer. People memorize facts and figures like this all the time. It's easy to recall them for tests and to prove you understand the material. Where things start getting interesting is when you need to provide context around the answer.

Space Data Centers Are Dumb.
Space Data Centers Are Dumb. YouTube video by Kyle Hill

Thank you @khill.bsky.social for making a video that I’ve been talking about on the @techfieldday.com Rundown for weeks. Space data centers are dumb because space isn’t cold. Among other reasons. youtu.be/-w6G7VEwNq0

I didn't want to have to do it, but I see no other choice.

IPv6 is the "AI IP Address". If you aren't using IPv6 you're already behind in the AI race.

Sam Altman at the Cisco AI Summit:

"I would like for AI to listen in on things and provide value."

What value? How? That's the thing no one is answering. What value is being provided?

Watching the Cisco AI Summit and Jeetu Patel says (paraphrased): "We are running out of human data, synthetic and machine generated data are continuing to train models"

Am I the only one that sees issues with training models on made up data and hoping they don't hallucinate?

Yeah, it has been. People take the first bin they find, especially the old C group. Now that they charge to check a bag it's just going to get worse.

Did you have any issues with the overhead bins? I've heard the first 6 rows are having issues with people filling them up before those passengers can board.

52 years later, only known copy of Unix v4 recovered from randomly found tape, now up and running on a system β€” first OS version with kernel and core utilities written in C A heart-warming story for cold, stony sysadmin hearts.

The next time some tells you tape is dead.
