TL;DR Sourcing data directly from disk IS faster than caching in memory. I brought receipts. Because hardware got wider but not faster, the old methods don't get you there. You need new tools to use what is scaling and avoid what isn't. Introduction In part 1 I showed how some computer performance factors are scaling exponentially while others have been stagnant for decades. I then asserted, without proof, that sourcing data from disk can be faster than from memory. What follows is the proof.
A second lawsuit filed by an artificial intelligence company alleging a former employee stole trade secrets has been filed in California, just days after Elon Musk’s xAI alleged it had recently experienced corporate espionage. In this case, Scale AI, a leading AI data-labeling firm, sued competitor Mercor Inc. in federal court Wednesday, accusing the startup and a former employee of misappropriating trade secrets to win new business. Scale is valued at approximately $29 billion following a mas

Open AI CEO Sam Altman speaks at the annual Snowflake Summit in San Francisco, California on June 02, 2025. OpenAI is rapidly expanding its presence in India — one of the key markets for its flagship ChatGPT product. India is an appealing destination for U.S. tech giants, with companies ranging from Google to Meta betting on its huge — and young — population over recent years. OpenAI CEO Sam Altman visited the country in February this year and met with the country's IT Minister Ashwini Vaishn
Donald Trump Snubs Elon Musk Yet Again, Invites All of His Biggest Competitors to the White House Musk's biggest competitors were invited to the White House — but he wasn't. President Donald Trump is throwing a major party in the White House's recently paved-over Rose Garden for some of the biggest names in tech — but billionaire Elon Musk's name isn't on the list. As The Hill first reported, the upcoming event will see high-profile tech executives swing by for a visit, including Microsoft co
We're now less than week away from the Apple's September 9 event, where the company is all but certain to unveil the iPhone 17 line. This year's theme of "Awe dropping," which was featured in Apple's invitations to the media sent on August 26 doesn't reveal much by way of clues, though some think the heat-mapped Apple logo is indicative of better thermal cooling in the new models. But more importantly, we already know how to watch the Apple iPhone 17 event itself: The keynote will be livestreame

3D QR Codes Erik Demaine & Martin Demaine, 2025 In this exhibit, we're experimenting with the limits of QR (Quick Response) codes, in particular new ways to construct QR codes from physical material. Most of our QR codes are built from several layers of material (wood, paper, or acrylic), where each layer is a single color. Building in this way has an interesting constraint: each layer must be a connected piece of material. We use a greedy algorithm to find the most white pixels that can appea
For years, I relied on Spotify like millions of others. The convenience was undeniable stream anything, anywhere, discover new music through algorithms, and share playlists with friends. But over time, several issues became impossible to ignore: artists getting paid fractions of pennies per stream, fake Artists and ghost Tracks, AI music and impersonation, creepy age verification complicity and the fact that despite paying monthly, I never actually owned anything. So I decided to take back contr
[ITS] According to a conspiracy theory long popular among ITS and TOPS-20 fans, Unix's growth is the result of a plot, hatched during the 1970s at Bell Labs, whose intent was to hobble AT&T's competitors by making them dependent upon a system whose future evolution was to be under AT&T's control. This would be accomplished by disseminating an operating system that is apparently inexpensive and easily portable, but also relatively unreliable and insecure (so as to require continuing upgrades from
Just yesterday, IO Interactive revealed its first gameplay from its James Bond game, 007 First Light. While it’s set in its own continuity, it’ll still have some ties to the films and books—in fact, those ties are how IO got the reins of Bond in the first place. Press like IGN got to visit the studio prior to the recent unveiling, and it was there game director Hakan Abrak revealed part of IO’s pitch for the game was sculpting Daniel Craig’s face onto Agent 47, the star of its stealth-action fr

Apple Music app customers woke up to a new feature last week, although not many know it exists yet. Apple Music subscribers can now grab songs or playlists from other music platforms, notably Spotify, and bring them to Apple. The ability to transfer music from other music services is buried in the Music App settings. Initially tested in Australia and New Zealand last year, this transfer option has now been rolled out to the US, UK, Brazil, Canada, France, Germany and several other countries. It
Catchy songs have been around as long as there's been music, but what makes a song stick in our minds is still a mystery. I recently chaperoned the all-night graduation party at my daughter's high school. After hanging out at an all-games-and-rides-free arcade until 2 a.m., we took the graduates on chartered buses to a private all-ages nightclub in downtown Seattle. It boasted free unlimited fountain soda and snacks, a photo booth with props, a trivia contest, glow necklaces and, best of all, a
Fitness tracking company Polar has launched the Loop, a $200 screenless wearable that it says will have no subscription fees. Preorders opened on Wednesday, and the Polar Loop will start shipping on Sept. 10. Like other fitness trackers, the Polar Loop will log steps, sleep patterns and daily activity patterns. But Polar is touting the lack of a screen as "unobtrusive" and "discreet." Don't miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source. The
If I got a nickel every time a major entertainment company sued AI image and video company Midjourney, I'd now have 15 cents. On Thursday, Warner Bros. Discovery filed a copyright infringement lawsuit against Midjourney, following Disney and Universal's similar lawsuit earlier this year. The recent lawsuit alleges the AI company violated the entertainment company's copyright protections by allowing users to create images with characters like Batman, Scooby Doo and Bugs Bunny. "Midjourney thinks
Roborock is one of the better-known companies if you’re looking to buy a robot vacuum. Options range from the capable Qrevo Curv to the innovative Saros Z70, which comes with a mechanical arm and a handsome price to match. So it shouldn’t be a surprise to hear that Roborock is entering the robot lawn mower market, a category we test that’s dominated by companies like Husqvarna, Eufy, Sunseeker, and others. There’s also a new set of stick vacuums, an ultra-thin robot vacuum and a self-santizing
There was a time in 2012 when NBA fans from all over were stricken with Linsanity. Jeremy Lin was a benchwarmer for the New York Knicks for much of that season, until he helped the team lock down a seven-game winning streak when he replaced a sidelined Carmelo Anthony in February of that year. Lin's popularity exploded, and though he was traded in the following offseason, his dazzling performance cemented a lasting legacy. Lin left the NBA in 2019 to play internationally, and he just announced
If you know someone who appreciates a good tech gadget, they’ll be a big fan of these smart glasses. CNET’s Scott Stein says the Meta Ray-Bans are practical and, oddly, transformative. He’s gotten so used to them that sometimes he’ll start talking to himself and tapping the glasses to take pictures before realizing he’s wearing his regular ones. “I suddenly miss the extra features like a phantom limb,” he says. He also loves that AI is a "whimsical bonus" with the Meta Ray-Bans. “These are glas
Fresh on the heels of August's black moon is September's full moon this weekend, which will be among the most interesting full moons of 2025. It's coming with a total lunar eclipse, making it a blood moon. If you're in the US, you won't be able to see the upcoming lunar eclipse, but the moon should still appear redder than usual. The total lunar eclipse, which takes place on Sunday, will be visible primarily in Asia, Australia, Eastern Europe and Eastern Africa. Most of the rest of Europe and A
Android's big UI overhaul, Material 3 Expressive, was announced earlier this year and is preinstalled on the new Pixel 10 series of smartphones.

Google's focus with the UI overhaul is to make Android more personalized, colorful and livelier overall. It's easier to identify actions you want to take with

Below, we'll outline the best live TV streaming services to use to watch the game as it happens, wherever you are in the world and how to use a VPN if the match isn't available where you are. Lionel Scaloni's defending world champs sealed their place in next summer's tournament back in March, but today's nevertheless remains significant
In Brief Rivian is laying off around 150 workers — its second small staff cut in a matter of months — as the company readies itself for the all-important launch of its more-affordable R2 SUV next year. The company confirmed to TechCrunch that the new cuts were mostly to its “commercial” team, which deals with sales and service operations, and that affected employees will be eligible for rehire and encouraged to apply for other open positions.
