TikTok is officially challenging the law that could lead to a ban of the app in the United States. The company, which has long claimed that efforts to force a sale or ban of its app are unconstitutional, announced a lawsuit against the federal government.
In the lawsuit, TikTok claims that a divestiture of its business from ByteDance is "simply not possible," and that the "Protecting Americans from Foreign Adversary Controlled Applications Act" violates the First Amendment. "They claim that the Act is not a ban because it offers ByteDance a choice: divest TikTok's U.S. business or be shut down," the suit states. "But in reality, there is no choice. The ‘qualified divestiture' demanded by the Act to allow TikTok to continue operating in the United States is simply not possible: not commercially, not technologically, not legally."
The filing of the lawsuit is the first beat in what's expected to be a lengthy legal battle over the law, which

Why buy a Windows Hello webcam? Most laptops now include a webcam of some form or another, some with Windows Hello built in. Desktops don't, however. If you share an apartment with someone else (or just want to avoid typing in your password), Microsoft's biometric Windows Hello system uses a depth camera plus facial-recognition technology to log you in to Windows 10 or Windows 11 in a split second. And there's more: passkeys are hot, and they use Windows Hello as well.
Below, I've listed several Windows Hello webcams that I recommend. I start with 4K Windows Hello webcams first, if only because I really think that your appearance makes a difference in a video call. But the budget (and clearly the most popular) picks all use 1080p resolution instead. Want more information? I've included a buying guide and a FAQ after the best Windows Hello webcam picks. You can also review PCWorld's 1080p and 4K webcam buyer's guide for recommendations on webcams without Windows Hello support.
Why you should trust me: I've been a technology reporter and writer for 30 years, with 10 years covering consumer technology for PCWorld alone. I've written about Windows Hello and supported webcams since Windows Hello launched in 2015, and have authored a separate roundup of

Being faced with a near-dead phone and no way to recharge can be a little panic-inducing. A portable power bank can help keep that feeling at bay, giving your devices a quick charge no matter how far you stray from an outlet. Toss a small one in your pack for a partial refill on a smartphone, or grab a higher-capacity battery to take to the diner where you'll park it for the day to work on your laptop. We've tested dozens of battery packs for this guide over the past year to come up with our top picks and help you find the best portable charger to fit your needs.
What to look for in a portable battery pack
Battery type
Nearly every rechargeable power bank you can buy (and most portable devices) contain a lithium-ion battery. These beat other current battery types in terms of size-to-charge capacity, and have even increased in energy density by eight fold in the past 14 years. They also don't suffer from a memory effect (where battery life deteriorates due to partial charges).
One drawback you may have heard is the possibility of lithium ion batteries catching fire. To limit the danger, battery packs require internal mechanisms to limit things like voltage and pressure. While you should still make sure a battery isn't exposed to unnecessary stress like excessive heat, damage from drops or operating in freezing weather, battery packs are considered safe enough to bring on an airplane. According to the
