The Metaverse Will Need 1,000x More Computing Power, Says Intel

Posted by in categories: computing, mobile phones

“We will constantly be ‘within’ the internet, rather than have access to it, and within the billions of interconnected computers around us,” Ball wrote in his Metaverse Primer. Mark Zuckerberg described the metaverse similarly, calling it “an even more immersive and embodied internet.” Picture this: you strap on a headset or pair of goggles, flick a switch, and boom—you’re still standing in your living room, but you’re also walking through a 3D world as an avatar of yourself, and you can interact with other people who are doing the same thing from their living rooms.

Being constantly within the internet doesn’t sound all that appealing to me personally—in fact, it sounds pretty terrible—but the good news for those with a similar sentiment is that the “full vision” of the metaverse, according to Ball, is still decades away, primarily because of the advances in computing power, networking, and hardware necessary to enable and support it.

The Universe Might Be a Self-Learning Computer. Here’s What That Means

Posted by in categories: computing, particle physics, space

Albert Einstein and Stephen Hawking – the most famous physicists of the twentieth century — both spent decades trying to find a single law that could explain how the world works on the scale of the atom and on the scale of galaxies. In short, the Standard Model describes the physics of the very small. General relativity describes the physics of the very large. The problem? The two theories tell different stories about the fundamental nature of reality. Einstein described the problem nearly a century ago in his 1923 Nobel lecture 0, telling the audience that a physicist who searches for, “an integrated theory cannot rest content with the assumption that there exist two distinct fields totally independent of each other by their nature.” Even while on his deathbed, Einstein worked on a way to unite all the laws of physics under one unifying theory.

We toured Intel’s advanced chip making site in Oregon. Here’s how it works

Posted by in categories: business, computing, space

Yet despite the chip giant’s manufacturing struggles, it still maintains nearly 90% market share in data-center chips, compared with AMD’s 10%, according to data from Mercury Research. Intel has lost more ground in desktop and laptop computers, holding onto 83% market share and 78% share respectively, with the remainder going mostly to AMD, according to Mercury data.

After years of hearing about these problems, Wall Street had largely written off the company’s manufacturing prowess. Investors expected the company to move to a hybrid approach to chip making, contracting more of its chip manufacturing to TSMC and potentially to Samsung. Some analysts suggested the company go as far as spinning out the manufacturing business, as AMD did with what is now known as GlobalFoundries years ago.

But weeks after Gelsinger took over, he announced that the company planned to double down on its manufacturing business in an effort to return Intel to its roots, including a bid to compete with TSMC as a contract manufacturer. Since his return to Intel after nearly nine years as chief executive of VMware, he has shaken up the company’s executive team. That includes re-hiring several notable Intel staffers, including Natarajan.

Mathematician Hurls Structure and Disorder Into Century-Old Problem

Posted by in categories: computing, mathematics

The mathematician Ben Green of the University of Oxford has made a major stride toward understanding a nearly 100-year-old combinatorics problem, showing that a well-known recent conjecture is “not only wrong but spectacularly wrong,” as Andrew Granville of the University of Montreal put it. The new paper shows how to create much longer disordered strings of colored beads than mathematicians had thought possible, extending a line of work from the 1940s that has found applications in many areas of computer science.

The conjecture, formulated about 17 years ago by Ron Graham, one of the leading discrete mathematicians of the past half-century, concerns how many red and blue beads you can string together without creating any long sequences of evenly spaced beads of a single color. (You get to decide what “long” means for each color.)

This problem is one of the oldest in Ramsey theory, which asks how large various mathematical objects can grow before pockets of order must emerge. The bead-stringing question is easy to state but deceptively difficult: For long strings there are just too many bead arrangements to try one by one.

Microsoft has blocked all default browser workarounds in Windows 10 and Windows 11

Posted by in category: computing

When Patch Tuesday rolls around, we can usually expect a series of Windows problems to be fixed (and perhaps to see some new ones introduced), as well as new features added. But Microsoft also uses such updates to take things away — and this is precisely what has happened with the latest updates for Windows 10 and 11.

Microsoft, quite understandably, would like everyone to use its Edge browser, and has taken endless steps to ensure that it stays the default browser on as many computers as possible. With the latest operating system updates — specifically the KB5008212 and KB5008215 updates — the company has implemented a block on workarounds used by the likes of EdgeDeflector and Firefox to force links to open in a browser other than Edge.

A Man Accidentally Threw Out a Hard Drive Worth $357 Million in Bitcoin

Posted by in categories: bitcoin, computing, cryptocurrencies, transportation

And he’s been searching for it for a decade.

It’s a nightmare scenario that might become increasingly common in a world of digital currency. A man threw away an old PC hard drive while doing a quick spring clean of his home in Newport Wales, U.K., in 2013. Fast-forward almost a decade and he’s still desperately petitioning to be allowed to go through his local landfill.

The reason the man, 35-year-old IT engineer James Howells, wants to trawl through his local trash site is that the hard drive he threw out included a wallet with 7,500 Bitcoin.

Can Mushrooms replace EVERYTHING? | Concrete, Plastic, Meat, Leather

Posted by in categories: biotech/medical, computing

One promising solution to plastic pollution is mycelium or mushroom packaging. It is made of 2 ingredients: mushrooms and hemp. Mycelium is the underground network of very durable, thread-like filaments called hyphae. It is mixed with agricultural waste like wood chips, oat hulls, cotton burrs or hemp hurds.

IBM and Samsung team up to design vertical transport field effect transistors

Posted by in category: computing

Officials from IBM and Samsung announced at this year’s IEDM conference in San Francisco a collaboration on a new chip design that adds transistors vertically on a chip. As part of their announcement, they suggested that their vertical transport field effect transistors (VTFET) could double the speed of processor chips, or alternatively, reduce the power they use by up to 85 percent.

Since the beginning of digital technology, processing chips have been made by placing tiny transistors on a chip and connecting them. Over time, engineers have placed increasingly more transistors on chips that have remained roughly the same size—adhering, generally, to Moore’s Law, which states that the number of transistors on a should double every year. Engineers have known for a long time that there are limits to Moore’s Law—eventually, it would become impossible to add even one more transistor, much less double the number that are there.

So researchers are looking for other ways to make chips. But in the meantime, engineers continue to look for ways to add more transistors to conventional chips. In their announcement, IBM and Samsung have explained that they are taking steps to begin designing chips that can expand vertically. In a practical sense, the move was inevitable. As an analogy, when towns grew too big to be efficient, engineers began making buildings taller, essentially turning 2D towns into 3D cities. Officials and engineers at IBM and Samsung (and doubtless other corporations, such as Intel) suggest that now is the time to begin doing the same with microprocessors.

This 8-bit processor built in Minecraft can run its own games

Posted by in categories: computing, entertainment, physics

The months-long project demonstrates the physics behind the CPUs we take for granted.


Computer chips have become so tiny and complex that it’s sometimes hard to remember that there are real physical principles behind them. They aren’t just a bunch of ever-increasing numbers. For a practical (well, virtual) example, check out the latest version of a computer processor built exclusively inside the Minecraft game engine.

Stacking transistors could be the next big thing in chips.


IBM and Samsung have announced their latest advance in semiconductor design: a new way to stack transistors vertically on a chip (instead of lying flat on the surface of the semiconductor).
