I have only just recently started digging into data centres and water, and the way companies are hiding vital information is beyond belief. It is so, so dodgy.

The entire project to widely popularise the idea these concerns are "fake" makes so much sense in this context

Here’s a piece I wrote in 2007 about how an over-reliance on militarized drug war tactics has basically thinned out the herd and ensured only the most efficient and adaptive operations survived. We’ve been selectively breeding highly evolved supertraffickers for decades. Sit this one out, Stephen.

"Daniel" is about to suit up to remove thorns from the date. The fronds are lined w/2-6 inch needle-sharp thorns - sharp enough to puncture tractor tires. Workers wear thick, puncture resistant gloves & eye protection as thorns can cause severe injury or infections. #WeFeedYou

Species Slowdown: Is Nature’s Ability to Self-Repair Stalling? When scientists recently analyzed hundreds of studies of ecosystems, they were surprised to see a marked slowing in the rate of species turnover. If new species don’t replace old ones, they say, ecosystems may have less flexibility to respond to habitat loss and climate change.

Scientists have long predicted ecosystems would shift in response to warming, with some species moving out and others moving in. But a major new study has found the rate of turnover is declining, suggesting nature may be losing its ability to self-repair.

"Her office is also investigating federal agents’ shooting deaths of 37-year-old US citizens Renee Good and Alex Pretti on 7 and 24 January. And she is “confident” they will be able to pursue charges. Moriarty’s office set up a portal where photos, videos & eyewitness accounts can be uploaded."

Gotta love how academic books don't earn you money, but LLMs can make money off of stealing them in the aggregate and if you write enough, they can also profit from stealing your personality after you are dead.

According to PEW, teens in households making under $75K are more likely to use chatbots for help with all or most schoolwork. I read a comment on another platform that said this is amazing news because we are "finally going to close the achievement gap." That is not how I would interpret this data.
