Diving into eBPF: Building a Process Tracer from Scratch Today i want to share a story about how i ended up writing a simple process tracer for linux. Using eBPF in go to fix a github actions which i actually didn’t need. We will go over each piece and hopefully you will learn something form it.

What you need to know about SQLite A compilation of lessons about what the SQLite database engine can and cannot do. It’s written for Rails, but you can apply all the lessons to use SQLite generally.

Using Transformers.js for AI in the Browser A practical journey to use transformersjs.js to perform ML task directly in browser.

go-taglib This project is a Go library for reading and writing audio metadata tags. It provides a portable solution with no external dependencies required, thanks to an embedded WASM binary. The most interesting part is WASM. So there is no CGO invoke at all even though taglib is a C++ codebase. A very interesting approach

music-metadata Stream and file based music metadata parser for node. Supporting a wide range of audio and tag formats.

quill Simple mac binary signing and notarization from any platform (replacing the codesign utility for simple use cases).

Why did Windows 95 setup use three operating systems? why Windows 95 setup goes through three operating systems: MS-DOS, Windows 3.1, and then Windows 95. Why not go from MS-DOS straight to Windows 95?

Best Practices for Bulk Optimization of Queries in PostgreSQL After reading this article, you’ll learn about the techniques we use to analyze SQL query performance when dealing with millions of queries per day and monitoring hundreds of PostgreSQL servers.

Loading the World! OpenStreetMap Import In Under 4 Hours The OpenStreetMap (OSM) database builds almost 750GB of location data from a single file download. OSM notoriously takes a full day to run. A fresh open street map load involves both a massive write process and large index builds. It is a great performance stress-test bulk load for any Postgres system. I use it to...

SRE deep dive into Linux Page Cache In this series of articles, I would like to talk about Linux Page Cache. I believe that the following knowledge of the theory and tools is essential and crucial for every SRE. This understanding can help both in usual and routine everyday DevOps-like tasks and in emergency debugging and firefighting. Page Cache is often left unattended, and...

Tiny GraphRAG (Part 1) We’re going to build a tiny 1000 line implementation of a GraphRAG algorithm originally invented by Microsoft. I consistently hear people talk about this algorithm at meetups, but it appears there are several orders of magnitude of people talking about it than actually using it or implementing it. Likely because the reference implementation is enormous and rather complex. So let’s...
