Senate GOP budget bill has little-noticed provision that could hurt your Wi-Fi

arstechnica.com Unknown 2026-02-20 22:37:32

Sen. Ted Cruz (R-Texas) has a plan for spectrum auctions that could take frequencies away from Wi-Fi and reallocate them for the exclusive use of wireless carriers. The plan would benefit AT&T, which is based in Cruz's home state, along with Verizon and T-Mobile. Cruz's proposal revives a years-old controversy over whether the entire 6 GHz band should be devoted to Wi-Fi, which can use the large spectrum band for faster speeds than networks that rely solely on the 2.4 and 5 GHz bands.

Buyers should keep an eye on the possibility of rate cuts in the next few months. Tharon Green/CNET Mortgage market predictions have been clouded by economic uncertainty caused by the Trump administration's trade measures, deficit spending and geopolitical maneuvering. The big question hanging over the housing market is whether rates will rise due to tariff-induced inflation or fall due to a recession.

Asynchronous Error Handling Is Hard

news.ycombinator.com Nicholas Wilt 2026-02-20 06:35:17

(Ed. note: This article was originally published on The CUDA Handbook blog on November 2, 2023.) Every API designer has struggled with the question of how best to propagate errors to their callers, since before the term “API” was invented. Even decades ago (say 30+ years), interface designers knew to separate the error return from the payload, in functions that return other results to their caller. Since it is sometimes useful to know what not to do: My favorite example of an antipattern in th

The Project Hail Mary trailer looks like The Martian all over again (in a great way)

Andy Weir's sci-fi books are practically built to be turned into movies, especially in the hands of great writers and directors. That's what happened with The Martian, which was a delightfully nerdy self-published novel that was transformed into a thrilling film adaptation — thanks to Drew Goddard's script and Ridley Scott's bold direction. And I have a feeling the same will be true for the latest Weir adaptation, Project Hail Mary, judging from the first trailer released today. It's got everyt

Error handling in Rust

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
