The two versions of Parquet

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.

Everything I know about good API design

news.ycombinator.com Unknown 2025-11-06 04:10:09

Most of what modern software engineers do involves APIs: public interfaces for communicating with a program, like this one from Twilio. I’ve spent a lot of time working with APIs, both building and using them. I’ve written public APIs for third-party developers, private APIs for internal use (or consumption by a single frontend page), REST and GraphQL APIs, and even non-network interfaces like the ones for command-line tools. Like designing good software systems, I think much of the advice floa

STARBASE, Texas—A beehive of aerospace technicians, construction workers, and spaceflight fans descended on South Texas this weekend in advance of the next test flight of SpaceX's gigantic Starship rocket, the largest vehicle of its kind ever built.

Marshal madness: A brief history of Ruby deserialization exploits

Serious badminton players are constantly exploring different techniques to give them an edge over opponents. One of the latest innovations is the spin serve, a devastatingly effective method in which a player adds a pre-spin just before the racket contacts the shuttlecock (aka the birdie). It's so effective—some have called it "impossible to return"—that the Badminton World Federation (BWF) banned the spin serve in 2023, at least until after the 2024 Paralympic Games in Paris.
