Memory is slow, Disk is fast – Part 1

TL;DR Hardware got wider, not faster. More cores, more bandwidth, huge vector units — but clocks, IPC, and latency flatlined. Old rules like “memory is faster than disk” are breaking. To go fast today, you have to play the new game. “CPUs keep getting faster every generation” Over the past 20 years or so computer hardware has evolved such that some facts we “know” about computers are wrong. Even among computer scientists, or perhaps especially among computer scientists, intuitions are off tar

Japan's Creepiest Station

However, if travelling northbound in the direction of Niigata, the station takes on a vastly different character. The northbound platform is a 15 minute walk away from the main station building. A majority of this walk consists of a 70m descent down almost 500 steps into the Shin-Shimizu tunnel. The descent is terrifying, with little vision of what awaits you at the end as you venture further and further into the depths. Water from the nearby rivers can also be heard trickling into the tunnel at

White Noise Makes Beer Brew Faster, Scientists Claim

Music can make people do things faster, with running, dancing, and doing chores being good examples. It seems, however, that we’re not alone in picking up the pace at the sound of a good tune. Researchers have discovered that playing a sound commonly known as white noise can shorten fermentation—arguably the most important step in brewing beer—by 21 to 31 hours, without markedly changing the flavor. This could help breweries increase beer production without diminishing quality. How sound chang

Faster animations on iOS 26 makes even older iPhones feel like new

The design revamp brought about with iOS 26 brings all sorts of new animations along with the Liquid Glass visual treatments. With beta 6, Apple overhauled Springboard’s app launch animations for the first time in years. Apps now launch to full-screen much faster than before, accompanied a minor warp effect that is reminiscent of how Mac windows minimise to the dock. The faster animation speed makes a big difference. It really feels like iOS 26 made your iPhone faster, even several-year old mod

Earth Is Spinning Weirdly Faster, Making Tuesday One of the Shortest Days Ever

Earth's rotation is randomly speeding up, and nobody is quite sure why. These speedups, which have occurred several times over the last few years, haven't had any effect on daily life, but they also haven't gone unnoticed by science. Tuesday, Aug. 5 is the next date when Earth's rotation is expected to speed up, shortening the day by between 1.25 and 1.51 milliseconds. According to Time and Date, the current prediction is set by the International Earth Rotation and Reference Systems Service and

What to read this weekend: When the world spins out of control

I'm still chipping away at my summer reading backlog over here, and this week finally made it to Alex Foster's Circular Motion, which came out in May. And, wow, I wasn't quite ready for the emotional journey this one took me on. It's set in a near future — people ride OneWheels and going viral on social media is still a thing some strive for — where the megacompany CWC has created an extreme form of high-speed travel that allows people to zip across the world in no time flat. But, it soon become

Netflix admits it used generative AI in a big sci-fi hit to cut costs

is a news writer who covers the streaming wars, consumer tech, crypto, social media, and much more. Previously, she was a writer and editor at MUO. Netflix used generative AI to create a scene in the sci-fi series The Eternaut — a first for one of the streamer’s original shows or films. During an earnings call on Thursday, Netflix co-CEO Ted Sarandos said the use of AI was faster than using traditional visual effects tools and helped cut costs. “That VFX sequence was completed 10 times faster

Perplexity Comet

The Web Should Work For You We believe curiosity is a superpower. It’s the spark that propels humanity forward. Yet, the web—our greatest source of information—was never designed to nurture curiosity; instead we’ve been asked to “browse” it through a one-way lens. That’s why we made Comet. Comet gives curious minds a thought partner for every aspect of online life. Comet moves every tab or task into a simple space for asking more of the world. With Comet, the web becomes a tool of curiosity, h

Frequent Nightmares Linked to Faster Aging and Premature Death

If you often have nightmares, you may need to worry a bit more about your health. New research presented today at the European Academy of Neurology (EAN) Congress 2025 links frequent nightmares to faster biological aging and an over three times higher risk of premature death, even when taking into account other medical conditions. The researchers claim to be the first to demonstrate this association, which could have significant implications for how seriously one should consider persistent nigh

AMD claims Ryzen Threadripper 9000 is up to 145% faster than Intel Xeon

The big picture: AMD announced its Ryzen Threadripper 9000-series "Shimada Peak" processors at Computex but didn't provide any benchmarks to compare them against Intel's latest Xeon CPUs. This week, the company finally released official benchmarks for the new chips, claiming they are up to 145 percent faster than their Intel counterparts. According to AMD, the Threadripper 9980X HEDT processor is up to 108 percent faster than the Xeon W9-3595X in Corona Render, up to 41 percent faster in Autode

Rust compiler performance

Perhaps the most often repeated complaint about Rust is its slow feedback loop and long compilation times. I hear about it all the time; in Rust podcasts, blog posts, surveys, conference talks or offline discussions. I also regularly complain about it, being a Rust user myself! Recently, in addition to the usual compile times complaints, I also started noticing the following sentiments being expressed by frustrated Rust developers: “Why doesn’t the Rust Project care more about this pressing and
