PSA to newcomers, crossposting
#PSA: to newcomers!
Some of you might be tempted to #crosspost between 🐦 and 🐘. As a general rule of thumb, crossposting is frowned upon.
🐦 ➡️ 🐘: try not to do this, but if you really want to, avoid RTs & limit to personal tweets. Set post visibility on 🐘 as "unlisted", so the local timeline is less noisy.
🐘 ➡️ 🐦: usually fine, but don't crosspost replies or boosts, respect privacy of others.
Welcome again & hope you are here to stay.
If you weren't aware, astronomers don't have a great relationship with Musk. A big issue for us is the Starlink satellites, which due to their low altitude and high number, already regularly interfere with ground-based observations. #starlinked on Twitter has endless examples.
We get told it's the "price of progress" and that SpaceX will make space telescopes cheap anyway. But that's BS: development of advanced space tech is much more expensive than the launch.
Hey there Fediverse video fans!
The European Union has just set up its own official #PeerTube instance at:
Here are some of the video accounts you can follow:

Here's one of the videos by the EU Space Programme about climate change in the arctic:
#Introduction time - I’m 25 years old, living in LA, getting my PhD in Earth & Planetary Science. Prior to this, I received my bachelor’s degree in biology, and then went on to start doing research in #astrobiology at #NASA ‘s Goddard Space Flight Center. I specifically study potentially Earth-like planets that orbit stars smaller than our Sun. I work with computer models and data from #Hubble and the Keck Observatory!
Hi folks, thanks for the follows, I'm very slow to notice interactions on Mastodon still, sorry about that! I'm a Gen-Xer completing a PhD in information science in Canada. I tweet a bit about everything, my research, science and tech topics, media theory, art, archaeology, animals, etc. I'm kind of annoying, but hopefully in at least an entertaining way. I'm autistic, physically disabled, and she or they pronouns are just fine. Thanks y'all for being so welcoming, I tried to get into Mastodon before, but kept falling back to use Twitter. Now I plan to stay and get the hang of it. Oh, also I'm a metalsmith and make mixed media art (including music and games). So I post about those topics sometimes, too. Cheers, everyone! - Leah
Hello! I’m an #academic interested in how tech firms impact our social, political, economic & environmental world. I’m currently researching digital vulnerabilities surrounding unsecured consumer credit (i.e. buy now pay later platforms), & the political implications of #bigtech practices . Very concerned re #sustainability and #data & #surveillance #capitalism. New to Mastodon, come say hi & talk irresponsible business 🤓
I'll also hop on the #introduction train:
Hi, I'm Kendra! I am a librarian at a transportation research institute. I like to talk about transportation, environmental justice, climate change (collapse), unions, labor, scholarly publishing, neoliberalism, cargo bikes, and coffee.
Born in 1832, Jonathan is expected to turn 190 years old this year year, he is the oldest living land animal in the world, from #Seychelles
Last week a dozen scientists caused criminal damage to the UK headquarters of fossil fuel company Shell as part of our global #ScientistRebellion
We pasted scientific papers and poured fake oil, resulting in one arrest
how many scientists DOES it take to change a lightbulb?
one to change the lightbulb
and nine to co-author the paper
Did you know over 1000 scientists engaged in civil disobedience yesterday all over the world? This was massive: scientists are trained to be cautious, so getting this many to act should have been a top story.
Media coverage? Zero. An utter disgrace.
The answer may vary depending on users and communities, but let's discuss where the new follow-recommendation tool of Mastodon 3.5 leads us (https://github.com/mastodon/mastodon/pull/15945).
The evolution of a network where new users preferentially follow existing influencers can be modeled as a Price/BA network.
You end up with few large influencers.
Honestly, I'm not a fan...
Also, that carbon neutrality is mostly achieved by buying carbon offsets which is at best a very limited resource and at worst a total scam:
* Even if it would work as well as possible, the earth’s land ecosystems can only hold enough additional vegetation to absorb 40 - 100 GtCO₂e from the atmosphere.
* Once this additional growth is achieved (and that takes decades), there is no capacity for additional carbon storage on land.
* The world emits 55 GtCO₂e into the atmosphere per year. So all we can offset is 2 year’s emissions at most.
So even if it would work (but zero evidence so far), offsetting is not a sustainable solution: it is too little and too late because we need to cut emissions dramatically (by 40 GtCO₂e per year) in the next 20 years.
I'm starting to think that Machine Learning shouldn't be used for anything other than hard science. Use ML to create some scientific results (think protein folding or mathematical theorem proving) that can then be checked by first-principles based algorithms.
