🖼️ Dithering Explained – Part 1
A clear and educational introduction to the fundamentals of image processing and computer graphics, balancing intuitive explanation with algorithmic depth.
This first part introduces the concept of dithering — a clever technique that simulates shades and colors using only black-and-white pixels. It explains how ordered dithering with threshold maps can create the illusion of gray tones by varying pixel density. The author also discusses how dithering preserves image detail on limited-color displays and hints at upcoming posts exploring more advanced methods such as error diffusion.

🗄️ Kafka Is Fast — But I’ll Use Postgres
A sharp critique of hype-driven engineering, encouraging developers to favor simplicity and real-world efficiency over overdesigned infrastructures.
A comprehensive benchmark comparing PostgreSQL as a pub/sub and queue system against Kafka. The author demonstrates that with modern hardware and tuning, Postgres can handle workloads typically assigned to distributed systems like Kafka. The article promotes a pragmatic philosophy: ‘Use Postgres until it breaks’ — favoring simplicity over unnecessary complexity.
