FASTJSON 2

FlatBuffers is a cross-platform serialization library and interface definition system developed by Google. It uses schemas written in `.fbs` files and the `flatc` compiler to generate language-specific code, which constructs and accesses serialized buffers directly without first parsing or unpacking them. The shared buffer layout supports reading data across languages and schema versions, and is designed for memory-efficient transmission, storage, and access. The project provides code-generation and runtime support for languages including C, C++, C#, Dart, Go, Java, JavaScript, Kotlin, Lua, PHP, Python, Rust, Swift, TypeScript, and others. It runs on Windows, macOS, Linux, Android, and other systems with a recent C++ compiler, and is licensed under the Apache License 2.0.

Apache DataFusion is an extensible query engine written in Rust that uses Apache Arrow as its in-memory format. It provides SQL and DataFrame APIs, a query planner, and a columnar, streaming, multithreaded, vectorized execution engine for partitioned data sources. It supports CSV, Parquet, JSON, and Avro out of the box, and can be extended with custom data sources, query languages, functions, operators, and other workload-specific components. DataFusion is developed as an Apache Software Foundation project and is available as libraries and binaries for building database and analytics systems.

Fastino Labs is an AI company that builds open-weight language models for agentic AI. Its models are intended for fast type decisions such as intent routing, fact-checking, hallucination checks, and browser-agent tasks, and the video describes them as available for local use and through an inference API. The company’s site identifies GLiNER, GLiGuard, and the Fastino fine-tuning agent among its research and models.

Kotlin is a concise, multiplatform programming language developed by JetBrains. It is used to build backend, mobile, web, and desktop applications, including native Android applications, and supports object-oriented and functional programming, asynchronous code, and null safety. Kotlin Multiplatform lets developers share code across platforms such as Android, iOS, macOS, Windows, Linux, and watchOS while retaining platform-specific code where needed. Kotlin is included with current versions of IntelliJ IDEA and Android Studio.

jc-rs is a command-line parser that converts command output, file formats, and strings into JSON from a single static Rust binary with no runtime dependency. It provides 237 parsers and follows jc's JSON schemas, with the repository reporting 100% compatibility across 934 of 934 oracle-valid fixture pairs. It supports both ordinary JSON output and line-by-line NDJSON streaming as input arrives, including for growing logs. The project is distributed as static binaries for five targets, as five Rust crates, through npm and Homebrew, and as a scratch Docker image. Its compatibility tests compare against fixtures from jc and fail CI if compatibility falls below 100%; the repository also documents a published startup comparison of 4 ms for jc-rs versus 109 ms for jc.
