Show HN: VoxelChain – An Experimental Voxel Engine
VoxelChain is an experimental tool to create voxel worlds in the browser. The lighting is fully ray traced in real-time and there is powerful cellular-automata based programming system, which allows to create complex digital circuits and model the behaviour of voxels (behaviour such as falling sand or water).<p>Technology wise, I'm using WebGL2 for the rendering and the simulation is coded in C89 and gets compiled to WebAssembly (with multi-threading) using Clang. The simulation is basically a custom cellular automaton and is fully parallelized. Once WebGPU is released, I'm planning to run the simulation on the GPU, instead of the CPU, which will give a massive speed up.<p>I've been working on this project full-time for over a year now, and finally came to the point of realising a public version of it to play with. There is already some really cool stuff that the community has built, and it's super fun to see how everything evolves!<p>Let me know what you think and feel free to ask any questions :>

Show HN: Open-source APM with support for tracing, metrics, and logs
Uptrace is an all-in-one tool that supports distributed tracing, metrics, and logs. It uses OpenTelelemetry observability framework to collect data and ClickHouse database to store it.<p>You can ingest data using OpenTelemetry Protocol (OTLP), Vector Logs, and Zipkin API. You can also use OpenTelemetry Collector to collect Prometheus metrics or receive data from Jaeger, X Ray, Apache, PostgreSQL, MySQL and many more.<p>The latest Uptrace release introduces support for OpenTelemetry Metrics which includes:<p>- User interface to build table-based and grid-based dashboards.<p>- Pre-built dashboard templates for Golang, Redis, PostgreSQL, MySQL, and host metrics.<p>- Metrics monitoring aka alerting rules inspired by Prometheus.<p>- Notifications via email/Slack/PagerDuty using AlertManager integration.<p>There are 2 quick ways to try Uptrace:<p>- Using the Docker container - <a href="https://github.com/uptrace/uptrace/tree/master/example/docker" rel="nofollow">https://github.com/uptrace/uptrace/tree/master/example/docke...</a><p>- Using the public demo - <a href="https://app.uptrace.dev/play" rel="nofollow">https://app.uptrace.dev/play</a><p>I will be happy to answer your questions in the comments.

Show HN: Make 3D art in your browser using Lisp and math
Bauble is a toy that I've been working on for a few weeks, and I think it's reached the point where other people could have fun with it!<p>Bauble is based on raymarching signed distance functions, which are kind of like... 3D vector art? They're pretty common in the procedural art community and you can do some amazing things with them, but normally writing SDFs means writing low-level shader code.<p>I wanted to play with SDFs, but I found it very frustrating to translate "I want to rotate this" into "okay, that means I have to construct a rotation matrix, and then apply it to the current point, and <i>then</i> evaluate the shape...". So I made a high-level Janet DSL that compiles down to GLSL shader code so I could more easily play with mathematically defined shapes.<p>For more about SDFs, this mind-blowing video is what got me interested in the first place, and shows you what they're capable of in the hands of an expert: <a href="https://www.youtube.com/watch?v=8--5LwHRhjk" rel="nofollow">https://www.youtube.com/watch?v=8--5LwHRhjk</a>

Show HN: Watchlimits – Chrome extension to solve excessive video watching
Hi all, I'm an indie hacker and I've been working on watchlimits.com over last couple months.<p>It's a chrome extension that helps you set limits (greatly customizable) and provides you stats and various accountability features.<p>It only runs on the video streaming platforms (not everywhere) and it's privacy centric.<p>Almost all functionality is available for free, but some advanced features only available in the paid version (password protection, allowed youtube channels).<p>It's a pretty niche tool that originated from my own occasional struggles (lost sleep anyone?), even though many people don't have a need to use it, it solves a big problem for some people and that is in itself already a success. If you know someone who would find it helpful, please share!
Show HN: I made a pictionary game with Stable Diffusion
I used lixica.art to get image-prompt pairs. You are asked to guess the prompt. And given a score based on how close you were to the actual prompt.
