Load Test GlassFlow for ClickHouse: Real-Time Deduplication at Scale By Ashish Bagri, Co-founder & CTO of GlassFlow TL;DR We tested GlassFlow on a real-world deduplication pipeline with Kafka and ClickHouse. It handled 55,00 records/sec published by Kafka and processed 9,000+ records/sec on a MacBook Pro, with sub-0.12ms latency. No crashes, no message loss, no disordering. Even with 20M records and 12 concurrent publishers, it remained robust. Want to try it yourself? The full test setup

Painting with Math: A Gentle Study of Raymarching (2023)

Most of my experience writing GLSL so far focused on enhancing pre-existing Three.js/React Three Fiber scenes that contain diverse geometries and materials with effects that wouldn't be achievable without shaders, such as my work with dispersion and particle effects. However, during my studies of shaders, I always found my way to Shadertoy, which contains a multitude of impressive 3D scenes featuring landscapes, clouds, fractals, and so much more, entirely implemented in GLSL.

Who Knew Basketball Needed an Interactive LED Floor?

I stood on an indoor basketball court in Orlando, Florida, in mid-May, ball in hand and LeBron 15 sneakers on my feet, ready to run some drills. My instructor drew up a basic diagram for me to follow in my next drill using an iPad. He showed how he wanted me to start at the baseline, then curl up to the corner of the free-throw line before taking a pass and driving to the basket. Easy enough to remember.

The best Mini ITX PC cases of 2025: Expert recommended

zdnet.com Adrian Kingsley-Hughes 2026-03-18 15:00:36

I'm old enough to remember when PCs were huge, looming units. They had to be big to hold all the components that made up a PC. As gaming PCs became a thing, these were even bigger because the high-end components generated a lot of heat. In turn, the heat had to be dissipated with copious amounts of airflow. Thanks to Moore's law, components have become smaller and more efficient, to the point where even a gaming PC can fit into a surprisingly compact case. Also: The best portable power stations

Shaping Light – Volumetric Lighting

As I became more familiar with post-processing over the past few months, I was curious to push those newly learned techniques beyond pure stylization to achieve something more functional. I wanted to find new ways to enrich my 3D work which wouldn't be possible without leveraging effects and passes alongside custom shaders. As it turns out, post-processing is great entrypoint to enhance a 3D scene with atmospheric and lighting effects, allowing for more realistic and dramatic visuals. Because t
