Whether you want some quick and dirty data storage, or simply don’t have that heavy requirements for your local database system, SQLite is always a good choice. With its portable single-file …
Linux Fu: Databases Are Next-Level File Systems | Hackaday
It is funny how exotic computer technology eventually either fails or becomes commonplace. At one time, having more than one user on a computer at once was high tech, for example. Then there are th…
Building a RAG for tabular data in Go with PostgreSQL & Gemini
In this article we explore how to combine a large language model (LLM) with a relational database to allow users to ask questions about their data in a natural way. It demonstrates a Retrieval-Augmented Generation (RAG) system built with Go that utilizes PostgreSQL and pgvector for data storage and retrieval. The provided code showcases the core functionalities. This is an overview of how the
In a relational database, foreign keys are normally used to associate records stored in different tables, but wouldn’t it be nice to define relationships dynamically without having to add extra columns or tables? And while we’re at it, how about having sparse relationships by associating a record directly with any other record like “post X was last edited by user #123” or “post X was flagged for review by user #456” (who happens to be a moderator)?

Commissioned: The network edge is on its way to becoming the location where data is created faster than ever before, and where application innovation is
In machine learning and AI, vector embeddings are a way to represent complex data, such as words, sentences, or even images as points in a vector space, using vectors of real numbers.
At the end of the day, the digital circuitry in an FPGA chip are analog circuits. When they are operating within their bounds, they properly behave like ideal digital circuits. Usually you want you…
In the past few years we’ve seen the rise of low-power mesh networking devices for everything from IoT devices, weather stations, and even off-grid communications networks. These radio module…
If you’ve got a wireless keyboard or mouse, you’ve probably got a receiver dongle of some sort tucked away in one of your machine’s USB ports. While modern technology has allowed …
Identity, authentication, and authorisation from the ground up
In this post we will dive deeper and demystify how apps actually implement authentication. Do it right, and you barely notice it. But do it wrong, and you lock users out or open major security holes.
