Holographic ribbon aims to oust magnetic tape with 50-year life span and 200TB

news.ycombinator.com Mark Tyson 2026-01-30 12:58:24

Details behind HoloMem’s holographic tape innovations are beginning to come into clearer view. The UK-based startup recently chatted with Blocks & Files about its potentially disruptive technology for long-term cold storage. HoloMem is another emerging storage idea which relies on optical technology - to enable holographic storage. However, it cleverly melds the durability and density advantage of optical formats with a flexible polymer ribbon-loaded cartridge, so it can usurp entrenched LTO mag

How to scale RL to 10^26 FLOPs

news.ycombinator.com Jack Morris 2026-01-26 23:47:34

TLDR: Reinforcement learning (RL) is the next training technique for building frontier-level AI models. To make it better, we need to train on more data. The current approach of scaling many environments simultaneously is messy and complicated. Instead, I propose we find a way to do next-token prediction on the Web using RL. This way, we learn to reason from general web data, instead of just math and code. I’ve spent a good part of the past year in denial. I was in denial because when OpenAI r

Five companies now control over 90% of the restaurant food delivery market

While reading the latest results from Prosus, I realized there seems to be a trend that nobody is talking about. There is an obvious wave of consolidation in the food delivery market happening right before our eyes. The once-hot food delivery sector has gone cold faster than your DoorDash order. New entrants have disappeared as most of the VC money chases the cool and hip AI startups. Alongside a wave of acquisitions, the world's food delivery market is consolidating in the hands of 5 companies.

A Technical Look at Iran’s Internet Shutdowns Every time mass protests erupt in Iran, a familiar pattern follows: the flow of information stops. The internet slows to a crawl or disappears entirely. But how does a modern country survive cutting itself off from the internet? Wouldn’t that break everything?

LG Gram Pro 16 (2025) Review: Thin Is Still In

Last year’s LG Gram Pro 17 was a classic study in laptop compromise. Incredibly thin and light, it was a veritable marvel of engineering that weighed in at half the heft of a typical 17-inch notebook. On the other hand, it was an unstable performance dud that ran so hot it nearly burnt the hair off my legs. The compromise scales ultimately tipped against the Gram Pro in 2024, but I’ll give credit to LG for staying the course and continuing to iterate on this design, and fixing many of the flaws

Why GM’s CEO is still betting on electric vehicles (and racing)

GM was the first major US automaker to make the promise to go all-electric by 2035, just four years ago. Those promises have since turned into rough estimates under the second Donald Trump presidency, with the company softening language about its electrification goals. But GM is riding high on EV sales, and as CEO Mary Barra puts it, EVs are still the future — just on a delayed (and very flexible) timeline. “We still believe in an all-electric future,” Barra told The Verge in an exclusive inter
