WASM 3.0 Completed

news.ycombinator.com Unknown 2025-09-18 19:16:53

Published on September 17, 2025 by Andreas Rossberg. Three years ago, version 2.0 of the Wasm standard was (essentially) finished, which brought a number of new features, such as vector instructions, bulk memory operations, multiple return values, and simple reference types. In the meantime, the Wasm W3C Community Group and Working Group have not been lazy. Today, we are happy to announce the release of Wasm 3.0 as the new “live” standard.

I got the highest score on ARC-AGI again swapping Python for English

news.ycombinator.com Jeremy Berman 2025-09-20 09:53:47

I think ARC-AGI is still the most important benchmark we have today. It’s surprising that LLMs can win the math olympiad but struggle with simple puzzles that humans can solve easily. This highlights a core limitation of current LLMs: they struggle to reason about things they weren't trained on. They struggle to generalize. But they are getting better, fast. Last December, I got first place on ARC-AGI v1 with a score of 53.6%. A lot has changed since then. Thinking models had just come out and

Memory is slow, Disk is fast – Part 1

news.ycombinator.com Unknown 2025-10-11 00:50:01

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

Intel Patents 'Software Defined Supercore'

news.ycombinator.com Anton Shilov 2025-10-17 12:44:56

Intel has patented a technology it calls 'Software Defined Supercore' (SDC) that enables software to fuse the capabilities of multiple cores to assemble a virtual ultra-wide 'supercore' capable of improving single-thread performance, provided that it has enough parallel work. If the technology works as it is designed to, then Intel's future CPUs could offer faster single-thread performance in select applications that can use SDC. For now, this is just a patent which may or may not become a reali

How is Ultrassembler so fast?

news.ycombinator.com Unknown 2025-10-17 14:42:43

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. Assemblers take in a platform-dependent assembly language and output that platform's native machine code which runs directly on the processor. "Why would you want to do this?" you might ask. First, existing RISC-V assemblers that conform the the entirety of the specification, as and llvm-mc , ship as binaries that you r

Performance Speed Limits (2019)

news.ycombinator.com Travis Downs 2025-10-16 14:06:10

How fast can it go? Sometimes you just want to know how fast your code can go, without benchmarking it. Sometimes you have benchmarked it and want to know how close you are to the maximum speed. Often you just need to know what the current limiting factor is, to guide your optimization decisions. Well this post is about that determining that speed limit. It’s not a comprehensive performance evaluation methodology, but for many small pieces of code it will work very well. Table of Contents Th

How to slow down a program and why it can be useful

news.ycombinator.com Unknown 2025-10-22 22:38:35

Most research on programming language performance asks a variation of a single question: how can we make some specific program faster? Sometimes we may even investigate how we can use less memory. This means a lot of research focuses solely on reducing the amount of resources needed to achieve some computational goal. So, why on earth might we be interested in slowing down programs then?

OpenAI is improving ChatGPT voice mode

bleepingcomputer.com Unknown 2025-11-10 03:15:42

ChatGPT's Voice mode is already pretty good, but OpenAI is working on a new feature that will allow you to control how Voice mode actually works. As you can see in the screenshot below, OpenAI has added "Voice speed" to the ChatGPT web app settings for voice mode. This means you can control how fast ChatGPT can speak. You can lower it to 0.5x or make it as far as 2.0x. There is a slider that allows you to specify the ChatGPT pace. These options are currently hidden. Also, OpenAI has added "c

Crawling into a warm bed after a long, hard day is hard to beat, but it isn't always a given. As we work our way towards the fall, you're probably already looking forward to getting your electric heated blanket out of the closet. And if you don't already own one, now is the time to start shopping for one. But like other blankets, they do need some upkeep -- and things get more complicated when there is electricity involved.

Hackers Are Finding New Ways to Hide Malware in DNS Records

wired.com Dan Goodin 2026-01-09 04:30:00

Hackers are stashing malware in a place that’s largely out of the reach of most defenses—inside domain name system (DNS) records that map domain names to their corresponding numerical IP addresses. The practice allows malicious scripts and early-stage malware to fetch binary files without having to download them from suspicious sites or attach them to emails, where they frequently get quarantined by antivirus software. That’s because traffic for DNS lookups often goes largely unmonitored by man

Species at 30 makes for a great guilty pleasure

Earlier this month, Hollywood mourned the passing of Michael Madsen, a gifted actor best known for his critically acclaimed roles in Reservoir Dogs, Kill Bill, and Donnie Brasco, among others. Few obituaries have mentioned one of his lesser-known roles: a black ops mercenary hired to help hunt down an escaped human/alien hybrid in 1995's Species. The sci-fi thriller turns 30 this year and while it garnered decidedly mixed reviews upon release, the film holds up quite well as a not-quite-campy B
