Chemical process produces critical battery metals with no waste

news.ycombinator.com Laurie Winkless 2026-01-03 20:35:33

Olivine is a rather unassuming rock. Olive brown to yellow green in color, this hard yet brittle mineral is thought to be the most abundant in Earth’s upper mantle. Chemically, olivine is magnesium iron silicate, though it contains other elements too. Economically, it’s close to worthless. Its limited industrial utility stretches to gemstones, metalworking, ceramics, and occasionally, as a gravel for road construction. At some mining sites, olivine is a waste product, stored in piles on the surf

Teach Yourself Programming in Ten Years (1998)

news.ycombinator.com Unknown 2026-01-03 17:24:51

Why is everyone in such a rush? The conclusion is that either people are in a big rush to learn about programming, or that programming is somehow fabulously easier to learn than anything else. Felleisen et al. give a nod to this trend in their book How to Design Programs, when they say "Bad programming is easy. Idiots can learn it in 21 days, even if they are dummies." The Abtruse Goose comic also had their take. Let's analyze what a title like Teach Yourself C++ in 24 Hours could mean: Teach

Innovation demands processors that can keep up. Readily available processors are built on technology that is over 70 years old. This limits innovation. To meet modern demands, processors must be entirely reimagined, breaking free from the constraints that have plagued computing for decades. This spatial dataflow architecture supports general-purpose computing, without being bound by the constraints of traditional processor designs or limited by fixed-purpose accelerators.

Implicit parameters are always integers, and they must appear first before any other parameters in the function type signature. The first argument can then just be omitted when calling the function, like so: Functions may also have implicit parameters, e.g. we can implement a zero extension function that implicitly picks up its result length from the calling context as follows: Sail will also ensure that the output of our function has precisely the length bits('n * 'm) for all possible inputs

s.p.l.i.t is the most badass typing game I’ve ever played. It’s actually more of a hacking simulator, cyberpunk thriller and puzzle experience than a typing game, but its core loop is bookended by sequences of high-intensity letter pecking with gruesome consequences — think Mavis Beacon as designed by Ted Kaczynski — and the final scenes have a way of searing themselves into your psyche. Not to mention, the whole thing takes place on a keyboard, no mouse or gamepad. So I guess it’s technically o

This piece was inspired by this post by Aaron Boodman. I remember myself as a calm, quiet kid, happiest when I had a bunch of wires in my hands. My parents used to give them to me as toys along with a screwdriver and an old cassette player I could take apart and try to put back together. I was three years old. I didn’t know what I was doing, but I loved the feeling of exploring the insides of a machine, trying to understand how it works. In first grade, I was introduced to MS-DOS and Logo with

Ageing accelerates around age 50 ― some organs faster than others

Ageing of many tissues accelerates around age 50, according to an analysis of tissues in people ranging from teenagers to individuals in their sixties.Credit: Karen Haibara/AFP/Getty It is a warning that middle-aged people have long offered the young: ageing is not a smooth process. Now, an exhaustive analysis of how proteins change over time in different organs backs up that idea, finding that people experience an inflection point at around 50 years old, after which ageing seems to accelerate.

In sledgehammer every operation is encoded as a sequence of bytes packed into an array. Every operation takes 1 byte plus whatever data is required for it. Each operation is encoded in a batch of four as a u32. Getting a number from an array buffer has a high constant cost, but getting a u32 instead of a u8 is not more expensive. Sledgehammer bindgen reads the u32 and then splits it into the 4 individual bytes. It will shuffle and pack the bytes into as few buckets as possible and try to inline
