UnitedHealth uses AI model with 90% error rate to deny care, lawsuit alleges
For the largest health insurer in the US, AI's error rate is like a feature, not a bug.

IMPORTANT: It appears there’s a chance that the Trump-Vance White House is going to defy a federal court order to allow Pope Leo’s top ally Chicago Cardinal Blase Cupich and Catholic clergy to enter the facility for Ash Wednesday Mass.
This would be a historic confrontation between Trump and Leo.

Yeah, this. But also, I will soon need a replacement laptop. I want to be sure I can afford one.
I can’t believe you lefty Luddites hate tech so much that you embrace mRNA vaccines, heat pumps, electric bikes, hybrid work, renewable power (and awesome advancements in storage), space telescopes, and hot/cold running water but reject the planet destroying plagiarism enrich the worst people bots!

Better cash in those Best Buy gift cards soon!
“.. ‘many system vendors will go bankrupt or exit product lines due to a lack of memory. Mobile phone production will be reduced by 200-250 million units, and PC and TV production will be significantly reduced.’ Yikes.”

It's the old adage that a scientist can bring dinosaurs back to life but it takes a social scientist to tell you that's a bad idea.
People with liberal arts degrees learned how to think critically and with clarity. We’re the Cons’ worst nightmare. 😂

Are there still stories of Canadians being detained at the US border, or of Canadians unexpectedly denied entry?
That seemed to be a big thing in early and mid 2025 but not seeing news articles about that lately.

The more this project fails, the less bitter I am about the name Doug Ford gave it.
Mobilinx has completed only 45% of the track work for the Hazel McCallion LRT, which was supposed to be finished by fall 2024. A year ago the P3 consortium’s credit rating was downgraded (again) to BBB-, the lowest before junk status #p3fail globalnews.ca/news/1166970... #onpoli
Large portions of Hurontario LRT track still not laid, intersections unfinished | Globalnews.ca
Construction on the 18-kilometre, 19-stop light rail route between Port Credit and Steeles Avenue began in 2020 and was originally scheduled to be completed in 2024.

Some thoughts on Line 5, a week after opening.
It’s a strange feeling to feel optimistic – even if it’s cautious optimism – about Toronto’s transit future.

Lowell Green was a racist demagogue who used his CFRA radio show as a soapbox to rant about immigrants and target racialized communities in Ottawa
Contrary to Ottawa Mayor Mark Sutcliffe's eulogy here, Lowell wasn't proud of Canada – he wrote an entire book about how it wasn't white enough for him

One of the things I’d like to see is a wider north-south MUP from Queen & Strachan that’s clearly a cycling route.
It’s not great walking along that path sharing it with cyclists, even though most cyclists are aware and courteous in the park.

May this be as successful as that First Lady doc.
Warner Bros. Discovery streaming chief J.B. Perrette calls the upcoming ‘HARRY POTTER’ series “the biggest streaming event in the history of HBO Max and arguably in streaming, period.”
He added it will be “the streaming event of the decade,” promising deeper book adaptations.
