Britain’s state-owned electricity system operator has awarded Palantir a £21mn contract without inviting rival bids, arguing critical processes are too reliant on its tech to run a competitive procurement process Latest for @financialtimes.com: as.ft.com/r/7fe6c0b7-2...

Britain’s grid operator gave Palantir contract without inviting rival bids

Neso cited a legal exemption that removes the requirement to consider other suppliers if dependencies leave no alternative

I am sorry, I may have said this before, but there really are moments when British politics are astonishingly naive, and I really think this may have something to do with the fact that the British have not experienced occupation, tyranny, displacemen within living memory.

WTF - first BBC question to Pat McFadden "Are you focusing too much on the protestors, and not on the issue that millions care about: small boats?"

I've probably moaned about this before. Cross validation doesn't control overfitting (your model is still just as overfit). It (tries to) estimates predictive performance without being tricked by overfitting. Big difference.

Say I've got a train dataset and a test data set. I fit a linear model to the train set and evaluate within-sample error. Then I fit the linear model to the train set and evaluate with the test set (i.e. cross validation). The 2 models are identical and equally overfit. The metric is different.

Over on X, the far-right British Patriots have launched a hate campaign against the RNLI They are recording RNLI volunteers in order to dox them, reveal their identities and publish details of where they and their families live These men are dangerous

80 year-olds with pro-Palestine signs: arrested as terrorists. Greens planning to block a road, to highlight an existential crisis: sent down for years. Masked far-right thugs blocking roads and ports, using intimidation, obstruction & threatening behaviour: no arrests. The real two-tier policing.

College students’ increasing reliance on AI, John Paul Rollert argues, is teaching them a “knack for cutting corners, a disdain for community rules, and an assumption that a spirit of integrity, and the sacrifices it assumes, is the reserve of suckers and wimps”:

I actually got an inquiry from a prospective graduate student today that says “I have been following your work on [insert topic here] and it aligns closely with my background.” 🙏🏼 please please please stop using AI to draft your emails to grad school advisors. It’s not a good look. 👀

"So in summary: using AI for coding led to depression, apathy, existential dread, and worse software. Not good. Add on top of that the negative environmental, community, and economic impacts of AI, and it became extremely apparent to me that something's gotta change." brettcodes.com/im-done-usin...

I'm done using AI

Why I'm stopping using AI for coding (and anything else) after using it earnestly for a year and coming to understand the harms it causes on personal, societal, and environmental levels.

Unfortunately, at least in my field, we've reached a point where your academic patron cannot get you a job but they *can* blackball you in the field. Which is the worst of all possible worlds when it comes to abusive advisors.

Your academic future should not be dependent on a bizarre patronage model that doesn’t even give the benefits it once did (your patron calls someone in their network and gets you a job)
