Ethan Zuckerman wants to release a tool that would allow Facebook users to control what appears in their newsfeeds. His privacy-friendly browser extension, Unfollow Everything 2.0, is designed to essentially give users a switch to turn the newsfeed on and off whenever they want, providing a way to eliminate or curate the feed.

Ethan Zuckerman, a professor at University of Massachusetts Amherst, is suing Meta to release a tool allowing users to "unfollow everything" on Facebook.

The tool is nearly ready to be released, Zuckerman told Ars, but the University of Massachusetts Amherst associate professor is afraid that Facebook owner Meta might threaten legal action if he goes ahead. And his fears appear well-founded. In 2021, Meta sent a cease-and-desist letter to the creator of the original Unfollow Everything, Louis Barclay, leading that developer to shut down his tool after thousands of Facebook users had eagerly downloaded it.

Zuckerman is suing Meta, asking a US district court in California to invalidate Meta's past arguments against developers like Barclay and rule that Meta would have no grounds to sue if he released his tool.

Apple has a brand-new lineup of iPad Pro and Air models for the first time in well over a year. Most people would probably be hard-pressed to tell the new ones from the old ones just by looking at them, but after hands-on sessions with both sizes of both tablets, the small details (especially for the Pros) all add up to a noticeably refined iPad experience.

iPad Airs: Bigger is better

But let's begin with the new Airs, since there's a bit less to talk about. The 11-inch iPad Air (technically the 6th-generation model) is mostly the same as the previous-generation A14 and M1 models, design-wise, with identical physical dimensions and weight. It's still the same slim-bezel design Apple introduced with the 2018 iPad Pro, just with a 60 Hz LCD display panel and Touch ID on the power button rather than Face ID.

So when Apple says the device has been "redesigned," the company is mainly referring to the fact that the webcam is now mounted on the long edge of the tablet rather than the short edge. This makes its positioning more laptop-y when it's docked to the Magic Keyboard or some other keyboard.

NASA's senior leaders in human spaceflight gathered for a momentous meeting at the agency's headquarters in Washington, DC, almost exactly ten years ago.

These were the people who, for decades, had developed and flown the Space Shuttle. They oversaw the construction of the International Space Station. Now, with the shuttle's retirement, these princely figures in the human spaceflight community were tasked with selecting a replacement vehicle to send astronauts to the orbiting laboratory.

Boeing was the easy favorite. The majority of engineers and other participants in the meeting argued that Boeing alone should win a contract worth billions of dollars to develop a crew capsule. Only toward the end did a few voices speak up in favor of a second contender, SpaceX. At the meeting's conclusion, NASA's chief of human spaceflight at the time, William Gerstenmaier, decided to hold off on making a final decision.

No car company in recent years has been able to generate more news headlines than Tesla. Its original founders were among the very first to realize that lithium-ion laptop cells were just about good enough to power a car, assuming you put enough of them in a pack, and with critical funding from current CEO Elon Musk, the company was able to kick-start an electric vehicle revolution. But those headlines of late have been painting a picture of a company in chaos. Sales are down, the cars are barely profitable , and now the CEO is culling vast swaths of the company . Just what is going on?

Tesla had some good times

Always erratic , Musk's leadership has nevertheless seen the company sell electric cars in volume , profitably . What's more, Musk has at times been able to inspire faith in and devotion to his company's products in a way that makes the late Steve Jobs look like a neophyte—after the Model 3 debuted in 2016 , 450,000 people gave $1,000 deposits to Tesla for a product that wouldn't go into production for at least 18 months .

Of course, that example also illustrates a long-running concern with the company and Musk's investment-attracting pitches: overhyping and underdelivering. By 2018, more than one in five reservation holders wanted a refund after cheaper models were delayed and delayed .

Telecom provider CenturyLink left a couple in Oregon without landline phone service for two months, then sent a bill for $239.

CenturyLink customer Kirstin Appel and her husband live in Banks, a city with fewer than 2,000 residents in Oregon's Tualatin Valley. They keep a landline for emergencies because their only Internet service is satellite, and cellular service in the area is poor. Appel said they pay $41 a month for CenturyLink phone service.

CenturyLink phone service became spotty and intermittent around January 20 when winter storms hit the area and then went out completely on January 27, Appel told us. She contacted Ars nearly two months after the outage began, desperate for a fix because her various chats with CenturyLink customer service led nowhere.

People have been leaving public messages since the first artists painted hunting scenes on cave walls. But it was the invention of electricity that forever changed the way we talked to each other. In 1844, the first message was sent via telegraph. Samuel Morse, who created the binary Morse Code decades before electronic computers were even possible, tapped out , “What hath God wrought?” It was a prophetic first post.

World War II accelerated the invention of digital computers, but they were primarily single-use machines, designed to calculate artillery firing tables or solve scientific problems. As computers got more powerful, the idea of time-sharing became attractive. Computers were expensive, and they spent most of their time idle, waiting for a user to enter keystrokes at a terminal. Time-sharing allowed many people to interact with a single computer at the same time.

Part 0: The Precambrian era of digital communication (1969–1979)

Soon after time-sharing was invented, people started sending messages to other users. But since every computer spoke its own unique machine language and had its own way of storing and retrieving data, none of these machines could talk to each other. The solution to this problem came out of the Pentagon’s Advanced Research Projects Agency (ARPA), and was thus dubbed the “ARPANET.” When two different computers connected to each other through an “IMP” (Interface Message Processor, the first router) in 1969, it was a massive breakthrough .

War never changes , but Fallout 76 sure has. The online game that launched to a negative reception with no NPCs but plenty of bugs has mutated in new directions since its 2018 debut. Now it’s finding new life thanks to the wildly popular Fallout TV series that debuted a couple of weeks ago.

In truth, it never died, though it has stayed in decidedly niche territory for the past six years. Developer Bethesda Game Studios has released regular updates fixing (many of) the bugs, adding new ways to play, softening the game’s rough edges, and yes, introducing Fallout 3- or Fallout 4 -like, character-driven quest lines with fully voiced NPCs—something many players felt was missing in the early days.

It’s still not for everybody, but for a select few of us who’ve stuck with it, there’s nothing else quite like it.

“Gadgets aren’t fun anymore,” sighed my wife, watching me tap away on my Palm Zire 72 as she sat on the couch with her MacBook Air, an iPhone, and an Apple Watch.

And it’s true: The smartphone has all but eliminated entire classes of gadgets, from point-and-shoot cameras to MP3 players, GPS maps, and even flashlights. But arguably no style of gadget has been so thoroughly superseded as the personal digital assistant, the handheld computer that dominated the late '90s and early 2000s. The PDA even set the template for how its smartphone successors would render it obsolete, moving from simple personal information management to encompass games, messaging, music, and photos.

But just as smartphones would do, PDAs offered a dizzying array of operating systems and applications, and a great many of them ran Palm OS. (I bought my first Palm, an m505, new in 2001, upgrading from an HP 95LX.) Naturally, there’s no way we could enumerate every single such device in this article. So in this Ars retrospective, we’ll look back at some notable examples of the technical evolution of the Palm operating system and the devices that ran it—and how they paved the way for what we use now.

Signs point to Qualcomm’s Snapdragon X Elite processors showing up in actual, real-world, human-purchasable computers in the next couple of months after years of speculation and another year or so of hype.

For those who haven’t been following along, this will allegedly be Qualcomm’s first Arm processor for Windows PCs that does for PCs what Apple’s M-series chips did for Macs, promising both better battery life and better performance than equivalent Intel chips. This would be a departure from past Snapdragon chips for PCs, which have performed worse than (or, at best, similarly to) existing Intel options, barely improved battery life, and come with a bunch of software incompatibility problems to boot.

Early benchmarks that have trickled out look promising for the Snapdragon X. And there are other reasons to be optimistic—the Snapdragon X Elite’s design team is headed up by some of the same people who made Apple Silicon so successful in the first place.
