Puffy Cloud Mattress Review: Soft but Supportive

wired.com Julia Forbes 2025-10-20 02:35:00

I will admit that, once upon a time, I was not the Puffy Cloud’s biggest supporter. I’ve tested this memory foam mattress multiple times over my five-year mattress testing career and believed it simply wasn’t for me—too soft, not enough spinal support. Well, times change, don’t they? Granted, during my previous tests, I didn’t spend a whole week sleeping on the Cloud in my own bedroom, as I did this time. I now also consider myself a side sleeper, which has a whole other set of requirements than

Indices, not Pointers

news.ycombinator.com Unknown 2025-10-20 01:21:30

Indices, not Pointers There is a pattern I’ve learned while using Zig which I’ve never seen used in any other language. It’s an extremely simple trick which - when applied to a data structure - reduces memory usage, reduces memory allocations, speeds up accesses, makes freeing instantaneous, and generally makes everything much, much faster. The trick is to use indices, not pointers. This is something I learned from a talk by Andrew Kelley (Zig’s creator) on data-oriented design. It’s used in Z

Memory is slow, Disk is fast – Part 1

news.ycombinator.com Unknown 2025-10-17 21:50:01

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

Why the Pixel 10’s UFS 4.0 storage upgrade won’t actually speed things up

androidauthority.com Unknown 2025-10-22 00:30:28

Robert Triggs / Android Authority Our Pixel 10 AMA was filled with great questions, but a couple of them stood out to me regarding the upgrade to UFS 4.0 storage. If you missed the news, Google has finally ditched the aging UFS 3.1 flash storage type for the far more impressive data speeds of UFS 4.0 and Zoned UFS (ZUFS) technology to improve age-related wear and tear. That is, as long as your new phone has 256GB of storage or more. The 128GB Pixel 10 and 10 Pro still have UFS 3.1 memory, just

How is Ultrassembler so fast? Ultrassembler is a superfast and complete RISC-V assembler library that I'm writing as a component of the bigger Chata signal processing project.

Emulating aarch64 in software using JIT compilation and Rust by Manos Pitsidianakis on 2025-08-25 I was able to write a simple just-in-time compiled emulator for the aarch64 ISA (Arm A-profile A64 Instruction Set Architecture). The Armv8-A/Armv9-A specs are massive in size, so the initial scope is for basic functionality and almost no optional architectural features such as SIMD.
