my chickens are producing. so cool! eggs are incredibly beautiful

Sunday edition of the New York Times cost $13 in Canada!

does that mean that some relays don't store any data?

Really into roasting and cracking and eating hazel and walnuts these days. Delicious, and reminds me of my grandparents

listening to nostr rising by nvk reminds me of listening to let's talk Bitcoin 10 years ago with Andrea's

SETI will never report finding a real alien signal, and it cannot. Its not possible because assumes an artificial signal will repeat. That's exactly the opposite of what they should assume.

A good starting assumption is a "dark forest" scenario. Even if there aren't berserker aliens out there hunting down signals, any civilization will have its own bad actors. Thus, secure communications will be a priority for any technical society. If you repeat a signal, or worse, repeat certain elements of it, then that repetition makes it stand out for scrutiny. As a society develops its encryption, it will find certain patterns in the never ending arms race of encryption and cracking.

The origin of the artificial signal has to worry about three things : their location being known ; their message being cracked by bad guys ; and their message being readable by good guys. All other details have to conform to fit in that.

How to satisfy all conditions? You know those TOTP tokens you save for authenticating stuff online? Something like that. The algorithm underneath is a black box, and the output is unguessable in the few seconds its needed. This would hint that the security of an alien signal is proportional to the duration of the broadcast. But more importantly, a one way algorithm allows you to hop frequencies, divide parts across the spectrum, compress data, and then alter all of these characteristics randomly and still be readable to the good guys.

Or more simply : good encryption will look like background noise.

The signal will never repeat. In fact, repetition of a signal should be automatic disqualification for an intelligent origin.

And this is why I'm calling BS on that signal that SETI is looking at. Just my opinion.

great post. finishing each broadcast with" Heil Hitler" was the repetition that allowed the Brits to crack the Nazi code

here's a little short that explains how starship will get to Mars and back! I had no idea it would involve two Starships! https://youtube.com/shorts/4nR718ryFnQ?si=IKCOozwOZUPQ4oo5

just finished reading The Road by Cormac McCarthy. A stunning work of art. I cried at the end. And at night I awoke and reminisced about all the beautiful and terrible adventures of the man and the boy.

now I'm going back to the classics and reading the Merry adventures of Robin Hood by Howard Pyle. this is after enjoying Peter Pan so much. I want to read older and older English books

that's a noble goal! I just finished The Road, by Cormac McCarthy. It's not a kids book and it's incredibly dark yet at the same time it's made me love life

applying to renew my wife's permanent residency status. the government has made it an absurd labyrinthine process. For example: after you pay the $50, you need to upload a receipt to them to prove that you paid

I just switched from amethyst to Primal. amethyst wasn't loading notes properly. so far Primal has been way better in my opinion. threads are easier to read, and I was even able to figure out how to put up a profile picture, lol

why does Primal wallet want my email address? #nostr #zaps
