$20.6 Trillion Liquidity Migration:Why Zoomex is Redefining the Crypto Derivatives Landscape in 2026

⋅

April 24 2026 | Global — As structural changes reshape the crypto market, liquidity is increasingly moving across trading venues rather than concentrating in a few dominant platforms. Global crypto derivatives exchange Zoomex states that the shift is not driven by shrinking market activity, but by evolving trader behavior — with users prioritizing execution quality and trading efficiency over platform size. According to CoinGlass, total crypto trading volume reached approximately $20.6 trillion in Q1 2026, with derivatives accounting […]

A Coding Implementation on kvcached for Elastic KV Cache Memory, Bursty LLM Serving, and Multi-Model GPU Sharing

⋅

In this tutorial, we explore kvcached, a dynamic KV-cache implementation on top of vLLM, to understand how dynamic KV-cache allocation transforms GPU memory usage for large language models. We begin by setting up the environment and deploying lightweight Qwen2.5 models through an OpenAI-compatible API, ensuring a realistic inference workflow. We then design controlled experiments where we simulate bursty workloads to observe how memory behaves under both elastic and static allocation strategies. Through systematic measurement and visualization, we directly […]

Your AI Agent Backend Will Break in Production

Your AI Agent Backend Will Break in Production

⋅

A 3-level testing pyramid for SaaS teams shipping AI features that actually need to work. We broke our first AI agent backend in production on a Tuesday. Not because the model gave a wrong answer. Because the system around it wasn’t testable. A prompt change we considered minor cascaded through three tool calls, bypassed a guardrail, and returned corrupted output to a live user. No test caught it. No trace explained it. That’s the moment we stopped treating our agent […]

You’ve Been Using Z-Scores. But Do You Actually Know What They’re Saying?

You’ve Been Using Z-Scores. But Do You Actually Know What They’re Saying?

⋅

A Z-score is not just a formula you plug numbers into. It’s a question your data is asking and most people never hear it. Photo by Jean-Rene Chazottes on Pexels Let me start with a scenario. You’re looking at two students. One scored 78 on a biology exam. The other scored 62 on a physics exam. Someone asks you: “Who did better?” Your first instinct is probably: well, 78 is higher than 62, so the biology student did better. But what if […]

Crates.io: The Code Changes That Were Made

⋅

Cargo and crates.io were developed in the rush leading up to the Rust 1.0 release to fill the needs for a tool to manage dependencies and a registry that people could use to share code. This rapid work resulted in these tools being connected with an API that initially didn’t return the correct HTTP response status codes. After the Rust 1.0 release, Rust’s stability guarantees around backward compatibility made this non-trivial to fix, as we wanted older versions […]

How Visual-Language-Action (VLA) Models Work [D]

How Visual-Language-Action (VLA) Models Work [D]

⋅

VLA models are quickly becoming the dominant paradigm for embodied AI, but a lot of discussion around them stays at the buzzword level. This article gives a solid technical breakdown of how modern VLA systems like OpenVLA, RT-2, π0, and GR00T actually map vision/language inputs into robot actions. It covers the main action-decoding approaches currently used in the literature: • Tokenized autoregressive actions • Diffusion-based action heads • Flow-matching policies Useful read if you understand transformers and want […]

@scottjla on Twitter in reply to my pelican riding a bicycle benchmark: I feel like we need to stack these tests now I checked to confirm that the model (ChatGPT Images 2.0) added the “WHY ARE YOU LIKE THIS” sign of its own accord and it did – the prompt Scott used was: Create an image of a horse riding an astronaut, where the astronaut is riding a pelican that is riding a bicycle. It looks very chaotic […]

Closed-form solution to the nonlinear pendulum equation

Closed-form solution to the nonlinear pendulum equation

⋅

The previous post looks at the nonlinear pendulum equation and what difference it makes to the solutions if you linearize the equation. If the initial displacement is small enough, you can simply replace sin θ with θ. If the initial displacement is larger, you can improve the accuracy quite a bit by solving the linearized equation and then adjusting the period. You can also find an exact solution, but not in terms of elementary functions; you have to […]
