Pinned toot

Hey everyone! I juggle roles being a Postdoc at MISU (Stockholm University), research software developer, blogger and a person. Scientifically, I am trained in , fresh out of PhD a few months ago. I study geophysical flows and turbulence.

I also maintain a:

It dawned on me (only now) that I can follow artists on Pixelfed even if they post on Mastodon instances. 🙃

Do you know ? A group of scientists fighting fake news on climate change and health. They review viral "news" stories: make detailed comments with web annotations, a summary and a quantitative assessment.

High temperatures in widespread parts of Europe today.
Please heed advice from national meteorological services and stay cool and safe.

The northernmost inhabited #Arctic town, Longyearbyen on #Svalbard, Norway, just had 4 days with temperatures above 20°C, incl new record of 21.7°C on 25.7. Normal for July is 5.9°C.

(Yesterday cooler at “only" 11.2°C)

Etter fire dager med temperatur over 20 grader i #Longyearbyen, er det ikke riktig like varmt i dag. Likevel er det fortsatt varme luftmasser i nord. Men vestavind gjør at Longyearbyen ligger på 11,2 grader i dag kl 15 (normalen for juli er 5,9 grader).

Earth has blue skies and red sunsets. Mars has red skies and blue sunsets.

The sky on Earth is blue because gas molecules reflect blue light. Earth sunsets look red because all the blue light has already been filtered out.

The sky on Mars is red because dust particles reflect red light. Martian sunsets look blue because all the red light has already been filtered out.

Two planets. Opposite skies.

Also, fun fact, the word green probably derives from the (reconstructed) proto-indo-european language root "ghre–".

That same word eventually evolved into the word grow.

The colour green is named after things that grow! 🌱

Red was one of the first colours humans ever used in prehistoric art, made from red ochre, dating back thousands of years.

The colour orange had no name in Europe until the 15th century, when it was named after the fruit.

The colour pink had no name in Europe until the 17th century, when it was named after a flower.

the heat-death of mastodon is when we've all got our own single-user instances which have been defederated from everyone else

Posting on fedi is like collecting pebbles or crafting beads and then throwing them on a beach at low tide in the hope someone will like them

Elizabeth Warren wants answers on Facebook’s fact-checking loophole Hill.vox.com/recode/2020/7/16/21327049/facebook-factchecking-climate-science-elizabeth-warren-opinion

Facebook pretends opinion articles cannot be fact checked to appease Republicans & their donors.

Warren calls Facebook out. The first example was a fact check I did for Climate Feedback. One of the dumb arguments was that global warming had "paused". In 2019 (!) when warming was exploding! We need better climate stooges.

I am extraordinarily pleased to announce a new release of my refactoring source-to-source compiler for FORTRAN 77! So happy!

Reminder that (now) Professor Katherine L. Bouman led the development of the algorithm that captured our first picture of a black hole. She wrote a dissertation on taking pictures of black holes, she wrote software to take pictures of black holes, she was the person who named the algorithm based on her work, her name was first on the paper that described the algorithm, and then her software took a picture of a black hole.

She's not an astronomer, she's a computer scientist and electrical engineer, and she isn't a lone genius doing this in a garage, she's part of a global team of people from many different disciplines. There was a dozen people contributing code to the project. But she isn't a random team member that got attention because she was cute, she is in a very direct sense responsible for creating that picture, more than Elon Musk has ever sent a rocket to space or created an electrical car.
