If you want to make sure that your site can be manipulated agentically by Meta's Muse, do not block traffic from ASN AS32934, because if you did that, it might make it impossible for the Muse agents to reach your site. 🤡

MORAL
The moral is obvious. You can't trust code that you did
not totally create yourself. (Especially code from com-
panies that employ people like me.) No amount of
source-level verification or scrutiny will protect you
from using untrusted code. In demonstrating the possi-
bility of this kind of attack, I picked on the C compiler.
I could have picked on any program-handling program
such as an assembler, a loader, or even hardware mi-
crocode. As the level of program gets lower, these bugs
will be harder and harder to detect. A well-installed
microcode bug will be almost impossible to detect.

Getting Started Learning Morse
Morse code is suprisingly (to me!) fun. Want to learn? ### How to get started **HAVE FUN.** If you think Morse is easy to learn, it will be easy. If you decide that it’s hard, it will be hard. I thought I just needed to “grind” through frustration, and it probably set me back half a year or more. Relaxing and having fun was the best change I made! **Listen, don’t look.** Morse is a heard language. **Start Morse Machine early,** as soon as you know a small handful of characters. Don’t wait until you have learned all the characters. ### How to keep going When you miss a character, practice just **mentally dropping it** and moving on to the next one, don’t spend effort trying to recall the one you missed. (This will really pay dividends later!) Are you a fast typist? Are you learning with a keyboard? Early in your learning, some days, for maybe two minutes of daily drill, practice **saying the character out loud as you type it.** This is so that you don’t wire yourself to know where that sound lives on the keyboard but miss its meaning. The better you type, the more this is likely. Sometimes, just focus on intently hearing the Morse characters without attempting to decode them. I have found this surprisingly helpful. Talk about your learning process, including what challenges you encounter, as you do it. No minor challenge is too trivial to bring up, and nothing will be unique to you. Whether you use the `#MorseCode` tag on the fediverse, Reddit’s r/morsecode, your local club, Long Island CW Club, or CWops Academy, find mentors or learning partners and talk about it. Want more? I wrote a summary of what I wished I knew getting started after about a year that has lots of tips, tools, and topics.

Puzzle solving as an endurance sport and performance art piece!
The optimal solution to the classic "Tower of Hanoi" puzzle doubles
in length for every disc added to the tower. Drop by and watch
Ayliean attempt a SIXTEEN DISC tower!! It's going to take all day, so
don't watch the whole thing, but the base disc will only move once
at the half way point - what a highlight to be present for! This is
likely the longest Tower of Hanoi solve that any human has ever
done, but we'll never know and nobody really cares!
