Renewed iPad Pros pair nicely with iPadOS 26, and they’re quite affordable right now

9to5mac.com Michael Burkhardt 2025-07-20 04:01:30

A short while ago, I was browsing Apple deals on Amazon (as one does) – and something stuck out to me. High-end iPad Pros, particularly 12.9-inch models, are surprisingly cheap. I saw M1 models with 1TB and cellular for nearly $600. Given the recent iPadOS 26 overhaul that makes the iPad much more Mac-like, I figured these deals would be worth a share. While renewed iPad deals are the focus here because of their affordability, new iPad deals are also mentioned at the end. Renewed M1 iPad Pro d

When to make LODs: Understanding model costs

news.ycombinator.com Jason Booth 2025-07-17 18:56:35

When to make LODs Jason Booth 3 min read · Dec 26, 2021 -- Listen Share Understanding model costs I’m always amazed at how often I hear people talk about “poly counts” in modern rendering, as if that’s even a thing. But lore has a way of sticking around forever, far past its point of being useful. And quite frankly, I’m constantly seeing artwork created in substandard ways because of this lore. First, the cost of rendering something doesn’t really have much relation to how many polygons it ha

Local cuisine was on the menu at Cafe Neanderthal

Sixty thousand years ago, two groups of Neanderthals lived just a stone’s throw apart in what’s now northern Israel. But they had very different cultures when it came to food, according to a recent study. Archaeologist Anaëlle Jallon of Hebrew University of Jerusalem and her colleagues examined dozens of animal bones from both sites, looking for clues about Neanderthal meal prep. It turns out that something as mundane as the cut marks left by butchering an animal can reveal differences in ancien

A brief history of “three-parent babies”

technologyreview.com Jessica Hamzelou 2025-07-22 13:00:00

I can’t go any further without talking about the term we use to describe these children. Journalists, myself included, have called them “three-parent babies” because they are created using DNA from three people. Briefly, the approach typically involves using the DNA from the nuclei of the intended parents’ egg and sperm cells. That’s where most of the DNA in a cell is found. But it also makes use of mitochondrial DNA (mtDNA)—the DNA found in the energy-producing organelles of a cell—from a thir

Extending That XOR Trick to Billions of Rows

news.ycombinator.com Unknown 2025-07-19 06:15:41

Can we extend the XOR trick for finding one or two missing numbers in a list to finding thousands of missing IDs in a billion-row table? Yes, we can! This is possible using a data structure called an Invertible Bloom Filter (IBF) that compares two sets with space complexity based only on the size of the difference. Using a generalization of the XOR trick [1], all the values that are identical cancel out, so the size of this data structure depends only on the size of the difference. Most explan
