View in browser Issue #353 Sunday, June 29, 2025 Why the $25,000 car is going extinct Can’t find an affordable car anywhere? You’re not the only one. BY MARK DENT In late 2021, Ford released the Maverick, a compact pickup truck. At roughly half the cost and half the weight of the popular F-150, it was meant to be an antidote for excess, and it worked. With a manufacturer’s suggested retail price (MSRP) of $19,995 for the base level, the Maverick drew rave reviews from critics and a rush of inte

In the middle of March 1931, Virginia Woolf wrote a polite letter to a woman sixteen years her junior. The recipient, a feminist writer named Winifred Holtby, was embarking on a book-length study of Woolf’s work. ‘I should much prefer that the book should be, as you say written impersonally, from material in the British Museum,’ Woolf wrote. ‘My feeling is that when people are alive, so much personality is bound to creep in, that it is better for the critic to keep aloof as far as possible.’ By

In Brief With Meta successfully poaching a number of its senior researchers, an OpenAI executive reportedly reassured team members Saturday that company leadership has not “been standing idly by.” “I feel a visceral feeling right now, as if someone has broken into our home and stolen something,” Chief Research Officer Mark Chen wrote in a Slack memo obtained by Wired.

Over the years we, as a family, have been moving our purchases away from Amazon, except in one single place: Kindle ebooks. For me it's that I'm incapable of reading physical books (but my kindle unlocked my reading), and with a Kindle, I was limited as to where I buy my books. When I read that it was relatively easy to jailbreak all the Kindle models I used this as my opportunity to move to buying epub books and hopefully more of that money goes to the authors (in an ideal world…).

Error handling in Rust

news.ycombinator.com Felix Knorr 2025-09-27 20:28:25

On Error Handling in Rust The current standard for error handling, when writing a crate, is to define one error enum per module, or one for the whole crate that covers all error cases that the module or crate can possibly produce, and each public function that returns a Result will use said error enum. This means, that a function will return an error enum, containing error variants that the function cannot even produce. If you match on this error enum, you will have to manually distinguish whi

The news comes from researchers at Algoma University in Ontario, who found evidence that the human brain, of all things, possesses luminescent properties.
