The two versions of Parquet

news.ycombinator.com Jerónimo López 2025-12-14 08:34:32

A few days ago, the creators of DuckDB wrote the article: Query Engines: Gatekeepers of the Parquet File Format, which explained how the engines that process Parquet files as SQL tables are blocking the evolution of the format. This is because those engines are not fully supporting the latest specification, and without this support, the rest of the ecosystem has no incentive to adopt it. In my experience, this issue is not limited to Query Engines but extends to the tools within the ecosystem.

OpenAI says GPT-6 is coming and it'll be better than GPT-5 (obviously)

bleepingcomputer.com Unknown 2025-12-23 20:56:15

OpenAI's CEO Sam Altman told reporters that GPT-6 is already in the works, and it’ll not take as long as GPT-5. The GPT-6 announcement doesn't surprise me because OpenAI is slowly becoming a product-first company rather than research-focused. There's no denying that OpenAI's CEO Sam Altman overhyped GPT-5 and underdelivered. While GPT-5 isn't exactly bad and actually offers significant improvements over GPT-4 or o3 for coding, the rollout wasn't smooth and some people were expecting more than

A simple pixel physics simulator in Rust using Macroquad

news.ycombinator.com Unknown 2026-01-09 06:21:39

Sbixel Sbixel is a very simple pixel physics simulator I made to learn Rust. It uses macroquad for drawing — and I was pleasantly surprised by how simple and awesome it is! Quick demo (click for youtube link): ⚠️ This project is very basilar and doesn't have much ambition to go anywhere — it's mainly a learning sandbox. How It Works The simulation uses a "sector" system to reduce unnecessary processing by only simulating active areas of pixels. All settings related to simulation and perfo

Tracking source locations in the Futhark compiler

Posted on July 29, 2025 Futhark is a programming language meant for writing fast programs, but as is the case for every programming language meant for writing fast programs, it inevitably happens that a programmer will use it to write a program that is not fast. When this happens, the programmer will likely want to know why their program is not fast, and how to make it faster. A useful tool for answering such questions is a profiler - a tool that tells you how long the different parts of your p

World Curling tightens sweeping rules, bans firmer broom foams ahead of Olympics

news.ycombinator.com The Canadian Press 2026-04-05 21:00:29

World Curling has tightened its sweeping equipment rules heading into the Olympic season. The move, announced Friday, follows concern over firmer broom foams that many players said gave sweepers too much control. Several high-profile models — including some from Goldline, BalancePlus and Hardline — are now banned. Only brushes with less-firm foam are approved for competition, effective immediately.
