Good evening everyone!
I hope your skies tonight are clear and full of wonder.

Initial impression of Mastodon…

My wife and I signed up for a week of Hello Fresh delivery meals. The first one came. It was Pork Burgers with a sriracha sauce.

Instructions for cooking the burger was to put a heat up a good amount of olive oil in a pan then toss in the patties

Reader, even my oil burns got oil burns. Hot oil was flying out of the pan like a come to life Jackson Pollock unfolding on my stove. The cats huddled fearfully in a far corner of the house. Burger tasted good tho

You liked it a lot, so here’s more old computers

It’s only a toot if it comes from the Mastodón region of France. Otherwise it’s just a sparkling fart.

You have set up an extraordinary server. And an ecosystem that can enable people to do and write good science on #fediverse
Qoto.org is like #arxiv of fediverse.

If you've ever wondered why Tesla's FSD has gotten nowhere over the years, this provides a big clue. Managing complexity is the biggest challenge of large software projects. That's why good engineers care about software architecture, tests and documentation. Neglect those, and you'll sooner or later find yourself running just to stay still.

Made a cool little animation of particle in a box. Learning quantum is an interesting ride..

Holy hell the twitter exodus is **still** accelerating. The influx of new users is up about 33% from yesterday, our biggest day so far. We are now seeing over 1,300 new users every day on QOTO!

Interesting fact of the day: The same effect that cuased light in a prism to split up into different colors is what ultimately caused the first transatlantic telegraphic wire in 1858 to fail.

Morse code is transmitted as on-off signals, effectively square waves. Square waves are in fact made up of many different frequencies. Like in a prism different frequencies move at different speeds through a wire. Therefore as the on-off pulses traveled through the transatlantic telegraph wire the signal spread out like it does in a prism and ultimately the pulses would overlap and be indistinguishable.

The effect was so extreme that it took a message of only 98 words (the first message sent) over 67 minutes to send one way and a whopping 16 hours to confirm the message.

Whitehouse, a doctor with little mathematical understanding, thought he could solve the problem by increasing voltage, which we now know was a futile effort. He increased the voltage to the point he managed to short out the cable entirely and made it useless. However Lord Kelvin had already warned of the problem as was ignored and he came up with the law of squares to describe the problem which later was refined to give us the telegraphers equation. The telegraphers equation is still used today to model feedlines in radio transmitters and receivers.
