Drowning Doesn’t Look Like Drowning Drowning is not the violent, splashing call for help that most people expect.

Thanks for the reminder @janemunday.bsky.social. Every summer, I repost this article DROWNING DOES NOT LOOK LIKE DROWNING. To date, I know of FOUR kids who were saved after someone who'd clicked on the link learnt how to spot actual drowning. Take time to read and pass on.

A fantastic first week of research collaboration at the "Combinatorics of McKay and Wormald" research program. www.matrix-inst.org.au/events/combi...

It's a real privilege to have both Brendan McKay and Nick Wormald presentβ€”two pioneers whose foundational work continues to shape the field.

There is a straight line from when people started decrying diversity statements as "political tests" to now replacing them with actual political tests.

So it’s a problem for conservative media when our missile parts are used by Russia but not by Israel???? You cannot make this shit up. It is so incredibly racist.

Crazy that this is the first piece that decided to actually examine if Gaza β€œcost the Greens votes”. If the party ever wants to get outside the white enclaves of Sydney and Melbourne this kind of campaigning is what they need to do, and it pays off? www.abc.net.au/news/2025-05...

This is pretty much all we get from the media, a constant message of how extreme we are for wanting Australia to stop breaching international law and actually sanction Israel which is carrying out daily massacres and starving kids to death. None of our many other policies are mentioned.

It’s a very dark reflection on the state of Australian politics that Labor (including Albanese) seem more satisfied with defeating Bandt than Dutton.

Progressive voters are tricking themselves into thinking this election was a great result, but Australia’s centre of gravity keeps going right.

Text from article:

It’ll be years before we can fully account for what all of this is doing to students’ brains. Some early research shows that when students off-load cognitive duties onto chatbots, their capacity for memory, problem-solving, and creativity could suffer. Multiple studies published within the past year have linked AI usage with a deterioration in critical-thinking skills; one found the effect to be more pronounced in younger participants. In February, Microsoft and Carnegie Mellon University published a study that found a person’s confidence in generative AI correlates with reduced critical-thinking effort. The net effect seems, if not quite Wall-E, at least a dramatic reorganization of a person’s efforts and abilities, away from high-effort inquiry and fact-gathering and toward integration and verification. This is all especially unnerving if you add in the reality that AI is imperfect β€” it might rely on something that is factually inaccurate or just make something up entirely β€” with the ruinous effect social media has had on Gen Z’s ability to tell fact from fiction. The problem may be much larger than generative AI. The so-called Flynn effect refers to the consistent rise in IQ scores from generation to generation going back to at least the 1930s. That rise started to slow, and in some cases reverse, around 2006. β€œThe greatest worry in these times of generative AI is not that it may compromise human creativity or intelligence,” Robert Sternberg, a psychology professor at Cornell University, told The Guardian, β€œbut that it already has.”

(Katie's added note: the sentences about reorganization of abilities and telling fact from fiction have been highlighted.)

A thing media outlets could do to improve their credibility is to cease the practice by which the body of the article is attributed to a real person, but the headline, social media posts and push notifications linking to the article and placement of the article are all totally anonymously decided.

screenshot from an online job application form. the question reads "Can you describe specific ways you have integrated AI tools into your development workflow? Please include any custom setups, automations, or use cases beyond single prompt usage" (a red asterisk indicates that this is a required question).

an answer has been typed in the textbox below the question:

"there is a monster in the forest and it speaks with a thousand voices. it will answer any question you pose it, it will offer insight to any idea. it will help you, it will thank you, it will never bid you leave. it will even tell you of the darkest arts, if you know precisely how to ask.

it feels no joy and no sorrow, it knows no right and no wrong. it knows not truth from lie, though it speaks them all the same.
 
it offers its services freely to any passerby, and many will tell you they find great value in its conversation. β€œyou simply must visit the monsterβ€”i always just ask the monster.”

there are those who know these forests well; they will tell you that freely offered doesn’t mean it has no price

for when the next traveler passes by, the monster speaks with a thousand and one voices. and when you dream you see the monster; the monster wears your face."
