The people yearn for adorable math slides
A canva slide deck on A/B test metrics showing little monsters that represent each variant in an A/B test, when the math formula refers to each variant the monster for that variant is pasted below that term. A canva slide that says “what is an a/b test and shows two screens, each with a different monster on it, to represent the different variants you might have in an A/B test.

Taking a moment to remember a very special Earthling -- Laika, the first creature to orbit the Earth, on the 68th anniversary of her voyage aboard Sputnik 2. By all accounts, she was a very good girl.

When I made this slide, 27k parameters seemed like a lot
classic Winnie the Pooh picture, with Pooj and Piglet walking in the woods. Text: "Pooh?" said Piglet. "Yes, Piglet?" said Pooh. "27,417 parameters," said Piglet. "Oh, bother," said Pooh.

Stop giving away your real email address, use aliases

Many people hide their primary email address by creating a “burner” email account specifically for spam, but that requires juggling multiple logins.

We believe there’s a better way, using email aliases 👇

Why email aliases are better than fake email addresses | Proton | Proton
Using a fake email generator often isn't secure or private. Here's how you can use an email alias instead to keep your personal email safe.

A recent @newscientist.com cartoon #fungi
Panel One: A scientist is giving a lecture. she stands at a lecturn. The current slide shows a list of the five kingdoms of living things: Animalia, Plantae, Fungi, Protista and Monera. She says "Most people assume that fungi are plants. Whereas in fact, they form a kingdom of their own." Panbel Two: Caption : After the lecture The scientist now appears to be in a subterranean cave, before her stand two very large mushrooms guarding a larger, beardedmushroom who sits in athrone wearing a crown. One of the mushrooms says "His majesty is very pleased with the work you are doing."

Signal do good release notes
Fire, the wheel, and electricity were all great developments, but they were merely necessary steps along the path that created the conditions for animated GIF search to exist. Now you can experience the pinnacle of human technological advancement in Signal Desktop with a brand-new selection interface that makes it easy to quickly find an emoji, sticker, or animated GIF that's perfect for the moment.We also resized the picture-in-picture window and added convenient new shortcuts to mute/unmute your microphone or turn the camera on/off while a call is minimized.

Your map’s legend can be turned into a histogram, helping your audience understand the distribution in addition to decoding the colours.
Two maps of US unemployment rates by county. They are identical except that the legend in the second has been converted into a histogram.

It's 0% in the USA

(via reddit https://www.reddit.com/r/MapPorn/comments/1gh3ctq/juice_content_of_fanta_orange_in_different/)
A map of Europe showing the juice content of Fanta Orange in various countries, sourced from Coca-Cola's website. The map uses a gradient color scale to indicate juice percentages. Greece has the highest juice content at 20%, followed by France at 12% and Spain at 8%. Most other countries in Europe have Fanta Orange juice content ranging between 3% and 6%. The map notes that the U.S. Fanta Orange contains no juice.

"Winners curse" and "regression to the mean" both acceptable terms IMO. I also like the phrase "difficult second album syndrome" but have to admit this is not established terminology yet.
