Today we have a whole batch of category errors, picked out from the rash of submissions and a few that have been festering on the shelf. Just for fun, I threw in an ironic off-by-some meta-error. See if you can spot it.

Adam R. "I'm looking for hotel rooms for the 2026 Winter Olympics in Milan-Cortina. Most hotels haven't opened up reservations yet, except for ridiculously overprice hospitality packages. This search query found NaN facilities available, which equates to one very expensive apartment. I guess one is not a number now?"

 

Intrepid traveler BJH had a tough time at the Intercontinental. I almost feel sympathy. Almost. "I stare at nulls at home all the time so it made me feel comfortable to see them at the hotel when traveling. And what is that 'INTERCONTINENTAL W...' at the top? I may never know!"

 

Hoping to find out, BJ clicked through the mystery menu and discovered... this. But even worse, "There was no exit: Clicking Exit did nothing and neither did any of the buttons on the remote. Since I'd received more entertainment than usual from a hotel screen I just turned everything off."

 

Striking out for some streaming entertainment Dmitry NoLastName was silently stymied by this double-decker from Frontier.com.

 

No streaming needed for Barry M. who can get a full dose of fun from those legacy broadcast channels! Whatever did they do before null null undefined null? "Hey, want to watch TV tonight? NaN."

 

Hah! "That's MISTER Null, to you," declared an anonymous contributor.

 

And finally, another entirely different anonymous contributor clarified that there are apparently NaN cellphone towers in Switzerland. Personally, I'm intrigued by the existence of that one little crumb of English on an otherwise entirely German page.

President Trump signed a long-expected executive action on Thursday calling on U.S. Education Secretary Linda McMahon to "take all necessary steps to facilitate the closure of the Department of Education and return authority over education to the States and local communities." From a report: "We're going to be returning education, very simply, back to the states where it belongs," Trump said. "And this is a very popular thing to do, but much more importantly, it's a common sense thing to do, and it's going to work, absolutely." The move has been expected since early February, when the White House revealed its intentions but withheld the action until after McMahon's Senate confirmation. It now arrives more than a week after the Trump administration has already begun sweeping layoffs at the Education Department. According to the administration's own numbers, Trump inherited a department with 4,133 employees. Nearly 600 workers have since chosen to leave, by resigning or retiring. And last week, 1,300 workers were told they would lose their jobs as part of a reduction in force. That leaves 2,183 staff at the department -- roughly half the size it was just a few weeks ago. The order instructs McMahon to act "to the maximum extent appropriate and permitted by law," an acknowledgement that the department and its signature responsibilities were created by Congress and cannot legally be ended without congressional approval. That would almost certainly require 60 votes in the U.S. Senate to overcome a Democratic filibuster.

LG is shutting down Art Lab, its NFT marketplace for TVs. From a report: In a notice posted to its website, LG says it has made the "difficult decision" to close the platform on June 17th. LG launched its Art Lab app during the NFT craze in 2022, billing it as a way to "buy, sell and enjoy high-quality digital artwork" from your TV. It added new digital art to the platform through "groundbreaking" NFT drops, which users could purchase by scanning a QR code to complete transactions through Wallypto, LG's crypto wallet app.

Scientists at Zhejiang University have created the world's smallest LED display, featuring pixels just 90 nanometers wide -- roughly the size of a typical virus and too tiny to be seen with optical microscopes. The breakthrough, described in Nature this week, uses perovskite semiconductors that maintain brightness even at microscopic scales, giving them an advantage over conventional LEDs. The research team, led by Baodan Zhao, also demonstrated a larger display with pixels measuring about 100 micrometers (human hair width) that successfully rendered images including a spinning globe.

A United States District Court judge has approved a settlement between HP and customers who sued the company for firmware updates that prevented printers from working with non-HP ink cartridges. The class-action lawsuit, filed in December 2020, alleged HP "wrongfully compels users" to buy only HP ink by issuing updates that block competitors' cartridges. Under the settlement, HP admits no wrongdoing and won't pay monetary damages to affected customers, though it will pay $5,000 each to the three plaintiffs and $725,000 in attorneys' fees. HP has agreed to allow users of specific printer models impacted by the November 2020 update to decline firmware updates containing "Dynamic Security" features -- HP's term for technology that blocks cartridges using non-HP chips. The settlement applies only to 21 specific printer models, leaving numerous other HP printers subject to Dynamic Security restrictions. HP has previously paid millions in similar cases in Europe, Australia, and California related to printer bricking.
