conductor
Conductor is an event driven agentic workflow engine providing durable and highly resilient execution engine for applications and AI Agents
Project mention: Conductor, an orchestration engine for microservices and event-driven workflows | news.ycombinator.com | 2025-10-05 -
ANTLR
ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files.
Project mention: RCParsing VS ANTLR - a user suggested alternative | libhunt.com/r/RCParsing | 2025-09-19ANTLR is a lexer-based, powerful tool for creating own DSL and analyzing them. But it's and overkill for simple languages (JSON, for example), while RCParsing is good for both complex and simple languages, allows you to choose: work with AST or immediately calculate value while parsing.

QR-Code-generator
High-quality QR Code generator library in Java, TypeScript/JavaScript, Python, Rust, C++, C.
Project mention: Fully vector QR codes with an SVG logo in React (download as scalable SVG) | dev.to | 2026-06-08That's what react-quick-response does. It renders the QR code as SVG (the encoding is handled by Project Nayuki's well-known QR Code generator library, bundled in — no extra runtime dependency), and it lets you pass an SVG logo as a child that stays vector too.

Is this reasoning, or measurement? If measurement, push it to a deterministic tool. Sonar, Spotless, Ruff, ESLint, coverage gates, pre-commit hooks, complexity calculators. Write a script if no tool exists. That's how just lint got built, and that's the Unix-philosophy move for agentic coding. Hooks fire on tool calls; CI fires on PRs; pre-commit fires on commit. Pick the cheapest layer that catches the failure and run it there.

fory
A blazingly fast multi-language serialization framework for idiomatic domain objects, schema IDL, and cross-language data exchange.
Project mention: Extend Protobuf/FlatBuffers Schema IDL with Shared/Circular Reference Support | news.ycombinator.com | 2026-03-11If you already have .proto or .fbs schemas and you want shared/circular reference support, with the Fory compiler you can keep those schemas, add a small set of Fory options, then foryc generates idiomatic native models across Fory-supported languages
With fory first-class object graph serialziation support, you can serialize object graphs without manual *_id link reconstruction or rewriting your entire schema into Fory Schema.

Well, for Java it's actually a separate compiler that targets Wasm and integrates with WasmGC: https://github.com/google/j2cl The Google Sheets team used it for their calc engine: https://v8.dev/blog/wasm-gc-porting
For Kotlin it's similar but the compiler backend is from Jetbrains themselves, targets Wasm and adapts the Kotlin runtime to use WasmGC: https://kotlinlang.org/docs/wasm-overview.html. https://seb.deleuze.fr/introducing-kotlin-wasm/ has some low level detail on how Kotlin works with WasmGC.
A bit more on Kotlin/Wasm here, seems like also Dart/Flutter uses WasmGC: https://developer.chrome.com/blog/wasmgc#kotlin_wasm
https://github.com/dotnet/runtime/issues/94420 has some notes on why C# can't use WasmGC (yet?).
