Bandit was experimenting with a new combat technique 😆

She spent several minutes following Minnie around like this.

Not sure how much credence to give the fact that Polymarket seems to indicate that Israel is attacking/has attacked Iran: https://polymarket.com/event/israel-strikes-iran-by-february-28-2026
Israel strikes Iran by February 28, 2026?

Polymarket

There is a hotel I have stayed at several times that continues to make me think it's actually a stealth escape room. There is art all over the hotel that seems to be puzzles, but I've never spent the time to actually solve them.

Note that the hard to see top left image here is a street map of a city, divided into diamonds, where very other diamond is transposed with another somewhere else on the map. Faint red cursive text appears to have been written on the map before the transposition.

I'm not sure what to make of the braille guide and the "Row" graphic, but it does strike me that "row" is almost a visual palindrome in braille.

Elsewhere in the hotel other art is paired with Morse code guides. The presence of the "standard ciphers" really triggers my puzzle hunt / escape room instincts.

I may have said this before, but it keeps being more true:

A vital skill to develop as a hacker is the ability to doubt the competence of others.

Humans are terrible at security. We mostly lack the mindset for it.
