I guess it's time for a #introduction. 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 #ScienceMastodon, 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 #TwitterMigration, 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.
Reddit signed a deal with Google to use its data to train LLMs. To celebrate, we made a firefox extension that lets you replace all your comments with any text of your choosing. All we ask is that you not choose something copyrighted. The New York Times is currently suing OpenAI for training ChatGPT on its copyrighted material, and we wouldn't want Reddit's uniquely valuable data to become hopelessly intermingled with that of litigious copyright-holders.
Wow, this could be a huge boon to competition and for worker piece of mind (I say as someone who has gotten lawsuit threats as a result of a non-compete clause). Gift link below.
"FTC bans contracts that keep workers from jumping to rival employers"
Well fascinating. "Gender concealment gap."
I wonder if this shows up in the disclosure of failures inside of workplaces. The part of me that did a dissertation on disclosure will NEVER shut up.
Considering women also get far steeper penalties FOR the disclosure of negative grades*, this is even more amazing because you'd think that would be extra incentive to conceal.

🎉 New preprint! 🎉
A short technical note—of interest to folks working on black hole perturbation theory. I give conditions for a handy gauge choice to also freeze the location of the event horizon of a black hole.
"Can a radiation gauge be horizon-locking?"

An #OTD thread from last year, about the scientific contributions of Julius Oppenheimer.
A lot of "common knowledge" about black holes – infinite redshift, the slow progress of an infalling observer from the point of view of a distant spectator – can be traced back to an influential paper Oppenheimer wrote in 1939.

Malik's 2020 paper identified 4 essential elements of successful iterated #PrisonersDilema:
1.Nice - never the first to defect
2. Retaliatory - cannot be exploited
3. Forgiving - willing to cooperate despite being defected on earlier
4. Clear - predictability makes it easier to cooperate
It's #4. that I fail at in my personal life. Wonder what a maverick strategy is good for in society? or why it persists in memes and genes? Hopefully it's not maladaptive.

We at WIRED reported 6 weeks ago that the hackers behind the Change Healthcare ransomware debacle received a $22 million payment. Only now has Change Healthcare confirmed that it paid—while also noting that stolen patient data is still at risk of leaking. https://www.wired.com/story/change-healthcare-admits-it-paid-ransomware-hackers/
In a society where privacy had any meaning at all, the top executives at UnitedHealth would be fired -- with no golden parachutes -- or, better yet, indicted for their incompetence and indifference. https://techcrunch.com/2024/04/22/unitedhealth-change-healthcare-hackers-substantial-proportion-americans/

The "Pillars of Creation", as seen from my driveway. This is the central structure in Messier 16, the Eagle Nebula which is now rising very early in the morning.
There is a newly discovered zero-day being used in the wild in yet another file transfer application -- in CrushFTP. It doesn't appear there is a CVE yet for this flaw.

Find out what that "#SeaLevelRise is 3.5 feet" means for where you live:
Adjust the level on the map to view the level of flooding for other values of SLR.
The link directs to the Boston area. At SLR = 5 feet, Cambridge is done. The Back Bay is a bay.
From worlds where stars do not twinkle, to lands where you must outrun the sun-rise to survive, "Alien Earths" by Lisa Kaltenegger is packed with truly delicious visuals of what we might find on the surface of an exoplanet.
Kaltenegger gives a personal account of what it's like working at the cutting edge of uncovering the nature of these alien worlds, with many amusing anecdotes such the perils of interdisciplinary work!
