President Donald Trump said Monday that he expects to put 25% tariffs on Canada and Mexico starting on Feb. 1, while declining to flesh out his plans for taxing Chinese imports. Trump made the announcement in response to reporters’ questions while signing executive actions in the Oval Office on his first day back in the White House. Trump threatened tariffs of as much as 60% on China during his campaign, but appeared to temper his plans after a phone call last week with Chinese President Xi Jinping.

A report from Mark Gurman in Bloomberg makes the very reasonable suggestion that automatic email categorization in Apple Mail, already present since iOS 18 arrived on the iPhone, is coming to Macs and iPads in a few months. The feature should arrive with macOS 15.4 and possibly iPadOS 18.4, both due in April. Similar to Google's server-side Gmail sorting, which debuted in May 2013, Apple's Mail app on iOS sorts email into categories: "Primary," "Transactions," "Updates," and "Promotions." Moving an email manually from one category to another generally fixes the categorization for that sender from then on.

For decades, we have been imaging the surface of Mars with ever-finer resolution, cataloging a huge range of features on its surface, studying their composition, and, in a few cases, dispatching rovers to make on-the-ground readings.

Veterinarians in the Washington, DC region have been put on alert for any unusual illnesses in their non-human patients amid today's presidential inauguration—a nod to the significance of potential zoonotic bioterror threats.

"As with any large-scale public event, there will be heightened security, and the region will be on alert or signs of bioterrorism or other potential threats," the letter read.

But expert musicians often experience a "ceiling effect," in which their skill level plateaus after extensive training.

I have one standard rack appliance in my home: a Unifi Dream Machine Pro. It is mounted horizontally in a coat closet, putting it close to my home's fiber input and also incidentally keeping our jackets gently warm. I can fit juuuuuust about one more standard rack-size device in there (maybe a rack-mount UPS?) before I have to choose between outer-wear and overly ambitious networking.
