KSON, a love-letter to the humans maintaining computer configuration
Hi friends, I'm really excited to introduce KSON, which just entered public beta! Anywhere a human is reading or editing YAML/JSON/TOML, KSON may be used as a more effective interface on that data. If you are such a human, we invite you to participate in this beta. tl;dr Check out the website [1], play with the online playground [2], install the library for your programming language [3], edit in your favorite editor [4], discuss and give feedback [5], contribute to the project [6]. (A personal note about this project: I love software. Machines made of words! Such a wonder. KSON…

In plain words
KSON is a configuration language designed as an alternative interface for reading and editing YAML, JSON, and TOML files. Now in public beta, it provides libraries for multiple programming languages and integrates with popular code editors. The project aims to offer a more effective approach to managing computer configuration data for developers and system administrators who work with these formats regularly.

From the sources
KSON - A love letter to the humans maintaining computer configurations. Robust and efficient like JSON, clean and readable like YAML.
Loading... KSON combines the strengths of YAML and JSON With KSON you can write files that are easy to read, edit, and debug—without worrying about invisible whitespace errors or missing commas. YAML promises human-friendly config , but in practice we struggle with whitespace sensitivity, poor error feedback, and opaque advanced features. JSON solves some of these problems but introduces its own: excessive quotes, no comments, strict comma rules, and nested structures that complicate diffs. KSON offers the best of both worlds: the readability of YAML with the robustness of JSON—and more. Loading... Kson is a superset of JSON Every valid JSON file is already valid KSON. Migration is instant…from kson.org

KodusOct 2025 · kodus.io · ▲145Hey everyone, Just wanted to share a quick update we just launched at Kodus. For those who don’t know it yet, Kodus is a code review agent that runs directly in your team’s Git workflow (GitHub, GitLab, Bitbucket… and now Azure DevOps as well). It helps maintain code quality and consistency by analyzing each PR based on your team’s own rules and repository standards. Support for Azure had been a common request — so if your team uses it, you can now plug Kodus right into your workflow and give it a try. Docs: https://docs.kodus.io/how_to_use/en/overview Repo:…

Visual flow-based programming for Erlang, inspired by Node-RED2025 · github.com · ▲243Hi There, Erlang-RED has been my project for the last couple of months and I would love to get some feedback from the HN community. The idea is to take advantage of Erlangs message passing and low overhead processes to have true concurrency in Node-RED flows. Plus also to bring low-code visual flow-based programming to Erlang.

eno [1] - A modern plaintext language w/ libraries [2] for JavaScript, Python, Ruby & soon more! We migrated a big relational research database to a file-based solution - requirements were: - Super fast and easy editability for users - Highest performance for parsing/validating >10K documents on every user change. Our trials with YAML/TOML showed us that we wanted something both faster [3][4] and easier [4], something tailored for file-based content management ... and after months of research & development it's now publicly available (under MIT license) for everyone!

I made a built-from scratch Wayland Compositor to display any GUI app* in the terminal! I think there is a lot of unexplored potential in custom Wayland compositors, a lot of really cool things you can embed existing applications into! So, I started with embedding apps into the terminal because that is the easiest input/output (output is just utf-8 and I use the great `chafa` library for that, and I just read from stdin for the input). If you have any other ideas for cool Wayland compositors, let me know. I purposedly wrote 80% the app in Typescript to appeal to the most developers and…

Years ago I stumbled across a basic version of this concept and it stuck with me. I knew if I was ever going to take on such a project, it would need to be flawless, but without coding experience it was just another idea that would never happen. By the end of 2024, as AI coding tools exploded everywhere, I finally had a way to make it real. I started from zero knowledge and spent months collaborating with AI agents as a learning experience. Every pixel and every function went through me. The AI translated what I asked for into code, but every decision was human. I didn't use existing OS…
