AWS Lambda Web Functions let you deploy standard Express, Hono, or Fastify HTTP servers without adapters, using active CPU billing to avoid paying for I/O wait. Each environment handles up to 128 concurrent requests, making it ideal for API backends and AI inference endpoints streaming token responses. This new form factor, built on Firecracker, complements existing Event Functions and MicroVMs within a unified operational model.
For platform engineers and cloud architects, this eliminates the adapter tax and I/O billing waste in serverless web workloads, directly competing with Vercel/Cloudflare Workers while keeping the stack fully within the AWS ecosystem.
Physical data layout is one of the most consequential decisions in lakehouse engineering. The author compares Liquid Clustering, ZOrdering, and partitioning across four workload types on Delta Lake, uncovering two undocumented failure modes that likely affect production systems today and offering a decision framework for choosing the right layout strategy.

This article likely provides a step-by-step guide to installing and running kagent, an open-source no-code agent builder from the CNCF ecosystem, directly on a laptop. It demonstrates how to create functional agents with tools using minimal input, making agent development accessible without extensive coding.
A visual, 10-minute deep dive into GitHub distributed architecture. Learn how Spoke clusters replicate Git objects, how fork networks share terabytes via alternates, how secret refs/pull/ branches work, and how ephemeral Actions runners authenticate with keyless OIDC.
12 October 2026 · 5 min Python used to have limited parallelism, due to its global interpreter lock (GIL). Only one thread could run Python code at a time. Python 3.14 comes in a free-threaded version ( python3.14t ), without the global interpreter lock. Several threads can now run Python code at the same time. Let us pick a realistic problem. GitHub publishes everything that happens on its public repositories: pushes, issues, pull requests, stars, and so forth. The GH Archive project collects these events
If you run a Kubernetes platform, you’ve probably got at least one Grafana dashboard for resource visibility on your workloads. The post GPUs on Kubernetes are bring-your-own-everything, starting with the bill appeared first on The New Stack .
Switching a FastAPI endpoint from `def` to `async def` without replacing blocking calls like `requests.get` with an async client (e.g., `httpx.AsyncClient`) can freeze the entire server, as the blocking call occupies the event loop. Benchmarks show a 20,000-fold slowdown (from 1.6ms to 34s) for an unrelated endpoint, and the anyio thread pool (default 40 threads) only protects `def` endpoints up to 40 concurrent requests, after which performance degrades sharply.
Cloudflare has opened a closed beta of its OHTTP Gateway, a managed endpoint that decrypts Oblivious HTTP requests for an origin. The design choice drawing attention is a refusal: the Gateway will not decrypt requests arriving from Cloudflare Workers or from hosts proxied through Cloudflare, because that would put client identifiers and request contents in the same hands.

React 19.3 was released on September 9, introducing several features including the react-dom browser() API. This API allows components to opt out of server-side rendering, addressing issues with components that rely on client-specific data. It provides a cleaner solution for managing hydration mismatches and supports conditional data fetching, enhancing flexibility for developers. By Daniel Curtis
Claude Code helped Linus Torvalds explore Linux read performance. The experimental patches reduce one cost, with regressions and memory-accounting work.
