Every time someone from the Other Place pops up over here, it's like sitting in a country pub in a snowstorm and seeing someone you really like coming in through the door.

For those making the #twittermigration : the Debirdify tool has been helpful in locating and re-following your community across the fediverse https://pruvisto.org/debirdify/

i reckon we will quickly face moderation related challenges with mastodon, as people (including griefers and trolls) decide to join, but because it's an open platform we have the potential to experiment with and pioneer moderation approaches ourselves, instead of relegating it to a black box in a birdsite

Censorship and Suppression of Covid-19 Heterodoxy: Tactics and Counter-Tactics

Controverses sur les connaissances et les politiques liées au COVID.
Pour contrer la menace que représentent les médecins et les scientifiques qui contestent la position officielle des autorités sanitaires gouvernementales et intergouvernementales, des partisans de cette orthodoxie ont entrepris de censurer ceux qui défendent des points de vue divergents.

More evidence of ancient ocean on Mars. https://www.universetoday.com/158429/scientists-piece-together-the-shoreline-of-an-ancient-ocean-on-mars/

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.
