Good! That's comforting. I'm just surprised that that level or coordination and dedication to a public good still exists in university IT departments and amongst the bean counters. May it long continue!

An Xkcd comic showing how dependency works, with an illustration where a small block is holding up a ton of other blocks, with the note that the one small block represents (in the sense of the comic) a passion project of a random coder in Nebraska upon which all modern technology depends to operate.

Why is ex-British PM Tony Blair involved in Trump's Gaza recovery plan? US President Donald Trump has unveiled his proposed peace plan for Gaza β€” pitching the return of a former British prime minister as its coordinator.

ADS has given astronomy THE BEST literature tools available anywhere. I almost never have to use the garbage that other academics have to suffer through (GoogleScholar, JSTOR, LexisNexis, WoS, PubMed...)

She basically invented astrophysics.
She proved the laws of chemistry, quantum mechanics, and statistical mechanics, not just gravity, applied universally.
She determined the composition of the sun and primacy of hydrogen in the universe.
She advised the PhDs of Frank Drake and Frank Kameny.

Finland ends homelessness and provides shelter for all in need - scoop.me In Finland, the number of homeless people has fallen sharply. Why? The country applies the "Housing First" concept agains homelessness.

β€œIn Finland, the number of homeless people has fallen sharply. Those affected receive a small apartment & counselling with no preconditions. 4 out of 5 people affected make their way back into a stable life. And all this is CHEAPER than accepting homelessness.”

It costs a lot less to house people.

Make fossil fuel exporters pay for the damage they are causing, not ordinary Australians Climate change is making natural disasters like fires, floods, heatwaves and drought worse, costing Australians billions every year. Make fossil fuel producers pay a climate disaster levy to help pay...

We’re calling on the government to introduce a National Climate Disaster Levy. A Levy like this would force the fossil fuel exporters, the companies that are causing this damage, to pay their fair share – not everyday Australians.

Sign the petition.

Another "climate wake-up call". Government says it's bad. Real bad.

That's funny, I remember reading something about the same people approving the expansion of Woodside's North West Shelf gas export project out to 2070.

The Loeb Scale: Astronomical Classification of Interstellar Objects 

Omer Eldadi, Gershon Tenenbaum, Abraham Loeb The Vera C. Rubin Observatory is expected to increase interstellar object (ISO) detections from a few over the past decade to potentially one per few months, demanding a systematic classification scheme. We present the Loeb Scale, formally the Interstellar Object Significance Scale (IOSS), a 0-10 classification system extending the proven Torino Scale framework, to address ISOs' unique anomalies, including potential technosignatures. The scale provides quantitative thresholds for natural phenomena (Levels 0-3) and graduated protocols for increasingly anomalous characteristics (Levels 4-7), with Levels 8-10 reserved for confirmed artificial origin. Each level specifies observable criteria and response protocols. We demonstrate the scale's application using 1l/'Oumuamua (Level 4), 21/Borisov (Level 0), and 3I/ATLAS (Level 4) as test cases. The Loeb Scale provides the astronomical community with a standardized framework for consistent, evidence-based and dynamic evaluation while maintaining scientific rigor across the full spectrum of possibilities as we enter an era of routine ISO encounters.
