Amazon CTO Werner Vogels, writing for Computer Weekly’s 60th anniversary, reflects on invisible engineering—the reliability work that only becomes visible when it fails—and what two decades at Amazon taught him about building systems that fade into the background.

Cohere's North Mini Code Megakernel Serving Engine
Today, Cohere presents a serving engine for North Mini Code built around a decode megakernel: BF16 on a single H100, 1.25× - 1.41× faster than vLLM end-to-end. Explore the code behind the serving engine on GitHub. Most LLM serving stacks still treat each forward pass as a sequence of kernels: launch QKV, wait; launch attention, wait; launch the MoE, wait. Each launch is fine on its own. The problem is the waiting in between. At small batch sizes, the GPU spends a surprising fraction of every decode step waiting rather than computing.

Among European Companies That Use a CDN, Nearly 9 in 10 Use Cloudflare
An analysis of 44,143 European companies that use a CDN found that 89.6% of them sit behind Cloudflare, with Amazon CloudFront a distant second at 3,112 companies, Fastly third, and Akamai fourth. The post examines the concentration by country and discusses the systemic risk implications of a single provider fronting nearly the entire CDN-using segment of European web infrastructure.

vLLM x AgentX: Optimizing for Real-World Agentic Serving
**TL;DR:** Agentic workloads are becoming a major source of vLLM traffic. Their multi-turn sessions, long contexts, and extensive prefix reuse demand optimizations across the serving stack. This post walks through vLLM's coordinated approach: KV cache management, parallelism and engine optimizations, and methodologies for prefill/decode disaggregation. Measured on AgentX, SemiAnalysis's public agentic benchmark, vLLM achieves up to 130K total tokens per GPU-second on DeepSeek V4 Pro, and an…

Understanding the Recent DDoS Attack Against Read the Docs
Read the Docs describes a ten-day DDoS attack in June 2026 that peaked at 5.5 million requests per minute, roughly 100 times normal traffic. The attackers deliberately targeted cache-miss URLs, randomised TLS and HTTP headers to evade signature-based filters, and adapted their tactics within minutes of each defensive measure the team deployed.

Serving LLMs on Tenstorrent Hardware: Inside the vLLM TT Plugin
vLLM and Tenstorrent introduce an out-of-tree TT plugin that registers Tenstorrent accelerators as a vLLM platform—covering mesh scheduling, single-process data parallel choices, and an unchanged OpenAI-compatible serving surface.

A Million Agents Is a Distributed Systems Problem
Once you run thousands of AI agents, the hard part isn’t prompts—it’s scheduling, fatigue, overload, and coordination. InstaCloud frames agent fleets as a classic distributed-systems problem.

Abandoning Scientific Linux Was a Mistake
Mohamed Elashri argues CERN and Fermilab undervalued Scientific Linux’s option value: after CentOS and RHEL source-access shifts, accelerator controls are now moving thousands of machines to Debian to keep old hardware alive.
