The JAWS shark is public domain

As we’re all celebrating the 50th anniversary of the movie Jaws, here’s something I bet you didn’t know: Due to a fluke of publishing and copyright law, the Jaws shark is public domain. It’s not the character of the shark that’s public domain – or someone would surely be making a low-budget horror prequel about how he became the Amity Island Killer. But I’m talking about the famous shark painting from the movie poster: Yep. That painting, the same one that appeared on the cover of the paperbac

Is Google secretly testing new AI voices in NotebookLM?

Andy Walker / Android Authority TL;DR NotebookLM users are hearing a mysterious third male voice during longer Audio Overviews. Google has confirmed that additional voices and dialects are coming, alongside APIs and video overviews, but it’s unclear if this third voice is a feature or a bug.

Study: Meta AI model can reproduce almost half of Harry Potter book

In recent years, numerous plaintiffs—including publishers of books, newspapers, computer code, and photographs—have sued AI companies for training models using copyrighted material. A key question in all of these lawsuits has been how easily AI models produce verbatim excerpts from the plaintiffs’ copyrighted content. For example, in its December 2023 lawsuit against OpenAI, The New York Times Company produced dozens of examples where GPT-4 exactly reproduced significant passages from Times sto

Meta is finally adding passkey support for Facebook and Messenger

Meta is finally adding passkey support for Facebook and Messenger on mobile devices. This should make for more seamless logins, as a passkey lets people sign in by using the same data they already use to verify their identities on a smartphone. This includes stuff like a PIN code, a fingerprint or a quick face scan. This is not only convenient, but more secure than traditional passwords. Passkeys are resistant to many types of malicious attacks, as they can’t be easily guessed or stolen. This w

Yes I Will Read Ulysses Yes

When Richard Ellmann’s James Joyce hit the shelves in 1959, the sheer size of the book (842 pages, 100 longer than Ulysses ) was as dazzling as the degree of detail. Joyce, who had been dead for 18 years, vividly inhabited its chapters, getting drunk, going blind, spending money, spiting enemies, cogitating, and, of course, creating a series of works that immediately made literary history. Moving briskly across the first half of the 20th century (not just a single day in Dublin), Ellmann spun a

Facebook will soon roll out support for passkeys on Android and iOS

Facebook is rolling out support for passkeys on both iOS and Android, the social network announced on Wednesday. Passkey logins make it harder for bad actors to remotely access your accounts because they require physical access to your phone. Unlike standard logins, passkeys use Face ID or Touch ID, a PIN, or a physical security authentication key to validate logins. Passkeys remove the need to rely on username and password combinations, which can be susceptible to phishing and other issues.

Meta is making all Facebook videos reels

is a news editor covering technology, gaming, and more. He joined The Verge in 2019 after nearly two years at Techmeme. Meta is making a change to how sharing videos works on Facebook. Right now, you can share videos as a video from the post composer or as a reel, and both have different sharing workflows. In “the coming months,” however, “all videos on Facebook will be shared as reels,” according to a blog post. “Facebook remains a home for all types of video – short, long, and Live,” Meta sa

Facebook announces that all videos on its platform will soon be shared as reels

Facebook announced on Tuesday that all videos on its platform will soon be shared as reels, regardless of their length or orientation.

Amazon Found a Way to Sell the MacBook Air 2025 at a Ridiculous Price, Much Cheaper Than on the Apple Store

Amazon and Walmart May Issue Their Own Company-Crypto

Retailers like Amazon and Walmart pay fees to credit card companies every time a customer uses their Visa or Mastercard. And it’s no secret that retailers are not happy with that chunk of change that gets siphoned off. But thanks to the emergence of digital money, these retailers are reportedly itching to get away from the big banks. In fact, they may even issue their own stablecoins, according to a new report from the Wall Street Journal. Amazon’s efforts to develop a stablecoin are still in t

How to download your information from Facebook

How to set up a WhatsApp account without Facebook or Instagram

There's no shortage of reasons to stay off the Meta ecosystem, which includes Facebook and Instagram, but there are some places where WhatsApp remains the main form of text-based communication. The app is a great alternative to SMS, since it offers end-to-end encryption and was one of the go-to methods to send uncompressed photos and videos between iPhone and Android users before Apple adopted RCS. Even though Facebook, which later rebranded to Meta, acquired WhatsApp in 2014, it doesn't require

I took my e-book library back from Amazon with this self-hosted app

Dhruv Bhutani / Android Authority If you’ve ever bought an e-book from Amazon, you already know you don’t really own it. Sure, it’s in your Kindle library and you can read it in the app. But try moving it to another device or archiving it somewhere else, and you’ll quickly run into walls. In fact, Amazon has been doubling down on its attempts to curtail access to the books you’ve bought from the Kindle store. Between DRM, proprietary file formats, and a complete lack of export tools, you are s
