FFmpeg devs boast of another 100x leap thanks to handwritten assembly code

news.ycombinator.com Mark Tyson 2026-02-02 17:51:41

The developers behind the FFmpeg project are again claiming major performance uplifts delivered by wielding the art of handwritten assembly code. With the latest patch applied, users should see a “100x speedup” in the cross-platform open-source media transcoding application. However, the developers were soon to clarify that the 100x claim applies to just a single function, “not the whole of FFmpeg.” BREAKING: FFmpeg 100x speedup from handwritten assembly13:55:30 <•haasn> rangedetect8_avx512: 12

Why Cartken pivoted its focus from last-mile delivery to industrial robots

techcrunch.com Rebecca Szkutak 2026-02-02 14:00:00

Autonomous robotics startup Cartken, known for its four-wheeled robots that deliver food on college campuses and through Tokyo’s bustling streets, has found a new area of focus: industrials. Cartken co-founder and CEO Christian Bersch told TechCrunch that applying its delivery robots to industrial settings was always in the back of his mind as they built the startup. When companies started reaching out about using their robots in factories and labs, Cartken took a closer look. “What we found i

Former Tesla president discloses the secret to scaling a company

Few companies have grown as quickly as Tesla, especially just before and after the company launched the Model 3, its first affordable EV. “We scaled Tesla in 30 months from $2 billion in revenue to $20 billion in revenue,” Jon McNeil, the former president of Tesla who is now co-founder and CEO of DVx Ventures, told the crowd at TechCrunch’s All Stage event in Boston. It wasn’t McNeil’s first time scaling companies, nor would it be his last. Previously, he founded six different companies, and a

Scientists Find Evidence of Grim Long-Term Effects of Fad Diets

Image by Getty Images Studies The way Westerners diet — often alternating dubious and restrictive food regimens with binge eating, in a phenomenon known as "yo-yo dieting" — may be messing with their gut flora and their brains.

I'm betting against AI agents, despite building them

Everyone says 2025 is the year of AI agents. The headlines are everywhere: "Autonomous AI will transform work," "Agents are the next frontier," "The future is agentic." Meanwhile, I've spent the last year building many different agent systems that actually work in production. And that's exactly why I'm betting against the current hype.

Larq Bottle PureVis 2 Review: Drinking Water as a Video Game Isn’t as Dumb as It Sounds

There’s something I learned about hydration that I can never forget: if you are thirsty, you are already dehydrated. It’s a rule of thumb that can come in handy if you are out on a long hike or on the beach in the middle of summer when the risk of becoming dehydrated is pretty high. But day-to-day, I rarely pay attention to how much water I drink or how dehydrated my body could be.

James Gunn Talks Future Superman Plans, Dropping Henry Cavill

James Gunn’s spent the past few weeks talking about why he agreed to do Superman, and he’s also taking time to address the awkward part: agreeing to do it at the apparent expense of Henry Cavill’s superhero comeback. In 2022, the mid-credits scene for Black Adam none too subtly declared Cavill’s return and his team up (or fight) with Dwayne Johnson’s thunderous antihero. Nothing came of that, however, because as Gunn explained in a recent Happy Sad Confused episode, it was “never part of the eq

The Hunt for a Fundamental Theory of Quantum Gravity

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally interwoven threads of space and time seem to stop short. These mysterious points are known as singularities. Singularities are predictions of Albert Einstein’s general theory of relativity. According to this theory, clumps of matter o

One of the best things about the Nintendo Switch 2 is its versatility.

That variety makes for several ways to play. From the upgraded Joy-Con 2 grips that introduce point-and-click mouse controls alongside the familiar motion tracking features, to the dedicated Swit

Will the Fear of Being Confused for AI Mean That We Will Now Write Differently?

by David Beer Could there be anything more insulting for a writer than someone assuming that their writing is an output of generative artificial intelligence? The mere possibility of being confused for a neural network is enough to make any creative shudder. When it happens, and it will happen, it will inevitably sting. By implication, being mistaken for AI is to be told that your writing is so basic, so predictable, so formulaic, so replicable, so obvious, so neat, so staid, so emotionless, s
