Hacker News with Generative AI: JSON

Fast columnar JSON decoding with arrow-rs (arroyo.dev)
JSON is the most common serialization format used in streaming pipelines, so it pays to be able to deserialize it fast. This post covers in detail how the arrow-json library works to perform very efficient columnar JSON decoding, and the additions we've made for streaming use cases.

Decoding JSON sum types in Go without panicking (nicolashery.com)
The Go programming language doesn't have native support for sum types, but we'll see how we can emulate them, how to decode and encode them into JSON, and how in some cases they can help avoid runtime panic exceptions.

Matching Regexps 200 Times Faster (eregon.me)
You might have seen @byroot’s excellent blog post series on optimizing the json gem. From the first blog post it’s clear most of the time for generating JSON is spent in generate_json_string() and specifically in convert_UTF8_to_JSON(), i.e., in converting Ruby Strings to JSON Strings.

Parsing JSON in 500 lines of Rust (krish.gg)
Last semester at university, I took a course called "Syntax-Based Tools and Compilers". It focused on building a scanner, parser, compiler, and so on for a language called PL0. We used Python in the course, but I was really interested in learning Rust at the time.

How (not) to sign a JSON object (2019) (latacora.com)
Last year we did a blog post on interservice auth. This post is mostly about authenticating consumers to an API. That’s a related but subtly different problem: you can probably impose more requirements on your internal users than your customers. The idea is the same though: you’re trying to differentiate between a legitimate user and an attacker, usually by getting the legitimate user to prove that they know a credential that the attacker doesn’t.

Optimizing Ruby's JSON, Part 5 (byroot.github.io)

Optimizing Ruby's JSON, Part 4 (byroot.github.io)
In the previous post, we established that as long as ruby/json wasn’t competitive on micro-benchmarks, public perception wouldn’t change. Since what made ruby/json appear so bad on micro-benchmarks was its setup cost, we had to find ways to reduce it further.

Optimizing Ruby's JSON, Part 1 (byroot.github.io)
I was recently made maintainer of the json gem, and aside from fixing some old bugs, I focused quite a bit on its performance, so that it is now the fastest JSON parser and generator for Ruby on most benchmarks.

Nobody gets fired for picking JSON, but maybe they should? (mcyoung.xyz)
JSON is extremely popular but deeply flawed. This article discusses the details of JSON’s design, how it’s used (and misused), and how seemingly helpful “human readability” features cause headaches instead. Crucially, you rarely find JSON-based tools (except dedicated tools like jq) that can safely handle arbitrary JSON documents without a schema—common corner cases can lead to data corruption!

JSON5 – JSON for Humans (json5.org)
JSON5 is an extension to the popular JSON file format that aims to be easier to write and maintain by hand (e.g. for config files). It is not intended to be used for machine-to-machine communication. (Keep using JSON or other file formats for that. 🙂)

A new JSON data type for ClickHouse (clickhouse.com)
JSON has become the lingua franca for handling semi-structured and unstructured data in modern data systems. Whether it’s in logging and observability scenarios, real-time data streaming, mobile app storage, or machine learning pipelines, JSON’s flexible structure makes it the go-to format for capturing and transmitting data across distributed systems.
