Multiplatform Matrix Multiplication Kernels

Few algorithmic problems are as central to modern computing as matrix multiplication. It is fundamental to AI, forming the basis of fully connected layers used throughout neural networks. In transformer architectures, most of the computation is spent performing matrix multiplication. And since compute largely determines capability, faster matrix multiplication algorithms directly translate into more powerful models [1 ]. NVIDIA probably deserves much of the credit for making matrix multiplicatio

AI CapEx Is Eating the Economy

AI capex is so big that it's affecting economic statistics, boosting the economy, and beginning to approach the railroad boom As ever, here is what's ahead: Updates on prior pieces My most recent Rough Notes essay A few things worth reading I previously wrote about the perils of building renovation as a Fed chair, especially given an administration bent on finding a reason to fire you "for cause."

James Gunn and DC Haven’t Started Casting Wonder Woman… Yet

The holy trilogy of James Gunn’s DC Universe is slowly coming together. Part one, of course, is Superman, which is now in theaters. A Batman movie is being written (in addition to Matt Reeves’ new Batman movie), and, of late, there’s been lots of talk about Wonder Woman too. As co-president of DC Studios, Gunn recently confirmed a Wonder Woman script is being written, and subsequent rumors suggested the film was being fast-tracked. Well, that’s partially true, Gunn said. “It’s a priority, but I

A huge fight looms over the NASA budget this fall

This has been a good week for the US space agency in terms of the federal budget. On Tuesday, a committee in the US House of Representatives passed a $24.8 billion budget bill for the coming fiscal year. Then, two days later a Senate committee passed a $24.9 billion budget for NASA. Both of these measures would keep funding more or less at the level of the current fiscal year and, for the most part, keep the space agency's programs going on their current trajectories. These bills are not final

This Dark and Atmospheric '90s Flick Is a Sci-Fi Classic, and It's Streaming Free on Tubi

The '90s were the heyday of techno-noir movies, flicks that combine the cynical atmosphere and jaded perspectives of film noir with the dystopian settings and altered reality of science fiction. Though movies like The Matrix may have exploded the popularity of the genre, there were also films that didn't get the attention they deserved on release. One of my overlooked favorites is Dark City, a mind-bending techno-noir thriller that explores the idea of identity against the backdrop of a city sw

Cursor snaps up enterprise startup Koala in challenge to GitHub Copilot

The startup behind the viral AI coding app Cursor is snapping up top talent from AI enterprise startups in a bid to bolster its competition with Microsoft’s GitHub Copilot and win over businesses looking to supercharge their employees with AI coding tools.

Subaru's third EV is the Uncharted (yep) with 300 miles of range and 338 horsepower

Subaru just screwed up our SEO with the launch of the Uncharted, an electric crossover with up to 300 miles of range that probably has nothing to do with the video game. It uses the same E-TNGA platform as Toyota's CH-R EV and strongly resembles that model. Due to arrive next year, the 2026 Uncharted will come in two versions, both with 74.7kWh batteries. The first is a front-wheel drive version with 228 horsepower and 300 miles of range, while the second is a much grunt-ier dual-motor four whe

A New Geometry for Einstein's Theory of Relativity

Kunzinger and Sämann wanted to use their new way of estimating curvature to determine whether these singularity theorems would still be valid if they no longer assumed space-time is smooth. Would singularities persist even in rougher, more realistic-looking spaces? It’s important to find out if the smoothness condition can be waived, Sämann said, because doing so would bring the theorems closer to physical reality. After all, he added, “we believe non-smoothness is an inescapable part of the nat

Experts lay into Tesla safety in federal autopilot trial

This week, a federal court in Miami started hearing a wrongful death case involving Tesla's crash-prone Autopilot driver assistance system. It's not the first time that Tesla Autopilot has been implicated in fatal traffic crashes, but it is the first time that a federal court has heard such a case. Until now, the most high-profile court case involving Tesla Autopilot was probably the California trial over the death of Walter Huang, who was killed in 2018 when his Tesla Model X steered itself in

If You Thought Your Life Was a Mess, Spare a Thought for Boeing's Massively Failed Starliner Spacecraft

Even after pouring $2 billion into its much-maligned Starliner spacecraft, NASA and Boeing remain committed to getting back off the ground. As Ars Technica reports, the head of NASA's commercial crew program, Steve Stich, revealed last week that Boeing and its propulsion supplier, Aerojet Rocketdyne, are making considerable changes to the astronaut shuttle following a disastrous first crewed mission to the International Space Station last year. The spacecraft experienced several "in-flight ano

Pixel Watch 4 pricing leak could mean good news for those fearing a hike

TL;DR A new Pixel Watch 4 leak has revealed that the pricing may remain unchanged from the Pixel Watch 3 in Europe. Unless there are any tariff impacts, this suggests US prices may also remain flat, starting at $349. With the upgrades to the specs of the Google wearable looking modest, it would be logical that there would be little to no price hike. It’s not too long now until we meet the Pixel Watch 4. While we’ve managed to get some insight into the specs and colors of the next Google weara

Gaming Laptops Have a Secret Weapon Against Desktop PCs, and It Looks a Lot Like the Switch 2

I want a future where we don’t need a desktop PC to get the best gaming graphics. Maybe I’m a dreamer who needs to keep on dreaming, but I think that that pie-in-the-sky wonderland is closer to reality than you may think, and all PC component makers need to do is hop on the eGPU train. Better yet, they need to make something that’s as easily dockable as a Switch 2, but with the added power of a discrete graphics card that could push a laptop or gaming handheld into a full desktop experience. Th

How China’s Patriotic ‘Honkers’ Became the Nation’s Elite Cyberspies

In the summer of 2005, Tan Dailin was a 20-year-old grad student at Sichuan University of Science and Engineering when he came to the attention of the People’s Liberation Army of China. Tan was part of a burgeoning hacker community known as the Honkers—teens and twentysomethings in late-’90s and early-’00s China who formed groups like the Green Army and Evil Octal and launched patriotic cyberattacks against Western targets they deemed disrespectful to China. The attacks were low-sophistication—

Garmin’s Morning and Evening Reports are so good that Fitbit should steal them

Kaitlyn Cimino / Android Authority I’ve always believed that more is better when it comes to health-tracking metrics. If I’m wearing a GPS watch all day and all night, I want to know what it’s picking up and how I can best use that to my advantage. And when I always have a Garmin on my wrist, I know exactly how much data I have to look forward to. I know that I can tap into a Morning and an Evening Report on my Forerunner 970, and I’ve noticed that it’s made a few of my colleagues jealous. The
