WAL Implementation in Golang
I wrote this simple WAL library in Golang that I use to write data that my kafka producer fails due to errors like Broker going down or some other issue. Took inspiration from etcd/wal
In plain words
WAL Implementation in Golang is a library for Go developers that stores data when a Kafka producer encounters errors, such as broker failures. Inspired by etcd's WAL (Write-Ahead Logging), it provides a simple mechanism to persist messages locally before they can be successfully sent to Kafka. The library helps prevent data loss in distributed messaging systems by maintaining a reliable queue when external services become temporarily unavailable.

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Many years ago, I made VJ softwares (to mix live visuals in clubs) for unexpected platforms like the Game Boy Advance, the Playstation 2 and the Raspberry Pi. This year, I’m back with a new web-app: Pikimov. Inspired by Photopea (a free Photoshop clone), I created this web-based motion design & video editor as an alternative to After Effects, to fill empty void. It's free, without signup, without cloud uploads (your files stay on your machine), and your projects are not used for AI models training.
