I guess it's time for a . I'm a theoretical physicist by training (PhD in quantum open systems/quantum information) and currently paying the bills as an engineer working in free-space optical communication (implementation) and quantum communication (concepts). I'm interested in physics and math, of course, but I enjoy learning about really any area of science, philosophy, and many other academic areas as well. My biggest other interest is hiking and generally enjoying nature.

I'm definitely interested in following , but I'm also just curious to see the mix of interesting photos and thoughts on myriad topics that may show up here.

I'm sort of part of the , but I honestly haven't used the bird site all that much in recent times, and as a FOSS/Linux geek I've been interested in federated services like Mastodon for quite a while.

@mekkaokereke

"people that choose other social networks are just evil, lazy, shiftless people who love to lick VCs boots"

This kind of absolutism really makes me despair. People will go where they feel comfortable. That is just a fundamental reality. And demeaning them for doing so is tragically self-defeating for Mastodon.

@mekkaokereke @james the VC rug pull is coming, but the Mastodon rug pull is present and perpetual. This post is only exemplary of, not particularly special:

- small instances are perpetually being fucked by the big ones.
- your social graph exists at the whim of every damn site it touches
- and we get a "you're doing mastodon wrong" for using it the way that even the algorithm averse ex twitter person wants to use it

I'm looking for some good resources on navigating conflict and difficult conversations in academia/science/the workplace for grad students and other early career researchers. Does that exist?

Hi all, I'm a french physicist from Marseille.

I work at the interface between statistical physics, network science and sociology (sometimes labelled #sociophysics or #ComputationalSocialScience). I'm basically interested in universal properties in human behaviour, and the mechanisms responsible for these properties.

I also teach maths, network science and Python in Aix-Marseille Univ.

a PSA since a lot of folks have been surprised to learn this: terminal programs often support the mouse! Try:

- opening `htop` and clicking a column header to sort
- opening `nano` (or vim, or micro) and clicking and dragging to select text
- using the scroll wheel in `mc` & clicking on the menus

it's really helpful if I forget a keyboard shortcut

Some friends are asking if I'll go to Bluesky. I don't want to, for reasons I'll explain. But people there can follow me at

And if you're on Bluesky and follow @ap.brid.gy and let me know, I should be able to follow you from here. Details to follow, including my problems with Bluesky.

One of my favorite things to do with students in the late fall is to take them outside and point first to the Orion nebula, then to the Pleiades, and finally to the Hyades cluster, saying, “These are snapshots in the evolution of open clusters.” Each of these systems is the home of young stars, but while the Orion nebula is very much a stellar nursery, with stars just 10 million years old or younger, the Pleiades, is more like a daycare center with stars 100 million years old or younger. At the same time, Hyades is more like an afterschool program for stars 730 million years old or younger. All these systems are filled with celestial children. In their youth, these stars still gather in clumps. But, as they age, the stars will drift apart until, as adults, they have no memory of the place they were born. Our Sun is one of these solitary stars and every time I introduce my students to these three open clusters, they ask what happened to the open cluster where our Sun was born.

The truth is, the cluster and our Sun had a falling out.

I think it's ok to tell you now that @anthrocypher and I have been collaborating on a scientific paper, that might also be a the-beacons-are-lit-Gondor-calls-for-aid thesis, might be the boldest thing I've written in developer science so far, might be something that only could've been written out of the liminal spaces that Ana and I both inhabit, and out of the joy of deciding we wanted to try to articulate science & community of practice wisdom together in one place and see where it took us

Over the past 24 hrs while Mastodon was discoursing about whether or not starter packs are OK, and if slow progress is more due to lack of funding or different priorities, and if people that choose other social networks are just evil, lazy, shiftless people who love to lick VCs boots or are people that just want a better UX...

If you're on BlueSky and want to bridge to Mastodon, follow @ap.brid.gy

That's it. Nothing to install, no terms of service to sign, no complicated garbage. If you want to stop, just block @ap.brid.gy

Details here: fed.brid.gy/docs

If you want to bridge your account to BlueSky, simply follow this account: @bsky.brid.gy

Why am I encouraging this? Because when BlueSky inevitably goes bad, people there will have friends in the Fediverse to help them move here.

I don't really know why people study astronomy in such great detail - except that it's fun. I think it's important to understand how the universe as we know it began about 14 billion years ago, and understand how the Earth was formed about 4.5 billion years ago, and how evolution brought us here. My life fits into this frame. But is it important to know the various dramatic ways that stars can die?

I don't think so... but it's sure fun!

Here's a tiny white dwarf star called a 'polar' sucking hot gas from its much larger but lighter companion. It's called a 'polar' because its magnetic field is so strong that the gas falling in is forced to move along the field lines, rather than forming the usual pancake-shaped 'accretion disk' and slowly spiralling in.

This means the ionized gas falling onto this white dwarf lands only on its north and south magnetic poles. It's like how ions from the Sun hit our Earth near its poles, producing auroras there. But it's vastly more intense! The magnetic field of a 'polar' is about 100 million times stronger than the Earth's magnetic field. And a lot more stuff is falling in. Now and then a *huge* amount.

So, polars are considered 'cataclysmic variable stars': now and then they blast out huge amounts of radiation, as a clump of infalling gas hits their surface. There are different kinds of cataclysmic variable stars. This is just one!

Now, why is it so fun to think about this... instead of, say, politics, or ecology? I guess the question answers itself. So now I'm wondering how much we can justify science based on escapism. Maybe a bit is okay. We need to have some fun, after all.

If you were chased here from Twitter, it's just possible that you won't be aware that a lot of people are now leaving Twitter (or X if you must) for BlueSky. I mention this because I personally very much valued having a thriving maths community on Twitter while still being part of the wider world, so to speak. My experience here, which may be as much my fault as Mastodon's, is that there are lots of interesting people but not quite the atmosphere that I liked on Twitter. It would be a bit cheeky of me to suggest deserting Mastodon, but perhaps you might like to consider trying out BlueSky -- I would be very happy if we could use it to recover what Musk stole from us.

saw someone describe LLMs as "an encyclopedia on steroids" and i think that's basically incorrect in every way, isn't it? i would have gone for something more like "a thesaurus on acid"

What does the income look like for a local newspaper?

The Halifax Examiner, a truly superb daily (@philmoscovitch writes for it) posted its tax return online here: halifaxexaminer.ca/morning-fil

... along with a summary

Nearly all the money comes from subscribers

It's a tight, tight ship!

(I subscribe myself, because the online daily blog is *amazing*)

The lesson for us all: If you have the money free, subscribe to support your smaller, truly local media

Mozilla has a survey open to the public about their future, and thoughts on tech. Who knows if responses will actually matter, but maybe add your own thoughts to balance out the inevitable flood of crypto and tech bros?

Remember, they just fired a giant chunk of their advocacy team, and they are abandoning the #fediverse. Their CEO's salary is $7MM. It was just over $2MM in 2018. Has Mozilla's value to you tripled in 6 years? Has YOUR salary tripled in that same time frame?

Mastodon, it's really simple.

You want everyone to leave the dodgy car salesman's X-hole?

You want a future where social media is community-owned and decentralised, instead of a corporate surveillance sphere?

Well, those things won't happen until Black Twitter migrates here.

And Black Twitter won't touch this place until there's proper moderation in place.

The issues raised by Mekka, Timnit, Kim, Sam, and others are not a peripheral issue.

Fixing moderation is absolutely central, core work that is mission critical for the Fedi being successful.

And if you don't do it, then please don't complain when (not if) everyone leaves for BlueSky.

EDIT: In terms of the kind of moderation tools that are needed, take a look at this post by Mekka: hachyderm.io/@mekkaokereke/112

Childhood mortality -- death before age 15 or so -- used to run at about 50%.

Every second child born, died before becoming an adult, all over the world, for as far back as we've been able to track.

We didn't turn the corner until about 1900, when science got us the germ theory. That sparked sanitation and vaccination.

A cabinet nominee (RFK Jr) who questions vaccines is frightening. A nominee who brags about not washing his hands (Hegseth) is terrifying.
