The .spec.externalIPs field for Service was an early attempt to provide cloud-load-balancer-like functionality for non-cloud clusters. Unfortunately, the API assumes that every user in the cluster is fully trusted, and in any situation where that is not the case, it ...

This week I'm talking with Adam Jacob, founder of System Initiative and creator of Swamp, about what happens when AI agents change the entire shape of software development. We discuss how he went from an 18-person team down to five ...
AI/ML and batch workloads introduce unique scheduling challenges that go beyond simple Pod-by-Pod scheduling. In Kubernetes v1.35, we introduced the first tranche of workload-aware scheduling improvements, featuring the foundational Workload API alongside basic gang scheduling support built on a Pod-based ...
"Is Rust a great fit for this project?" I get this question quite frequently so I think it's time to write down my thoughts if it can help to avoid
A TUI for managing chezmoi dotfiles.
Since its original implementation in the Linux kernel in 2018, Pressure Stall Information (PSI) has provided users with the high-fidelity signals needed to identify resource saturation before it becomes an outage. Unlike traditional utilization metrics, PSI tells the story of ...
Obs.js is a tiny inline script that helps you adapt your site to real-world network, battery, CPU, and memory conditions.
In compilers, static single information form (SSI) is a common extension to static single assignment form (SSA). It was introduced by C. Scott Ananian in 1999 in his MS thesis (PDF) 1. SSI extends your existing SSA intermediate representation by ...
What if your database worked more like Git? Every change captured as an immutable event you can replay, instead of a single mutating row that quietly forgets its own history. That's event sourcing, and Chris May is back on Talk ...

There’s promise, potential, and some reality checks if you want to go all in on solar power in famously unsunny places like Amsterdam
Volume group snapshots were introduced as an Alpha feature with the Kubernetes v1.27 release, moved to Beta in v1.32, and to a second Beta in v1.34. We are excited to announce that in the Kubernetes v1.36 release, support for volume ...
No-Vary-Search lets HTTP caches ignore irrelevant query parameters such as UTM tags, while still keeping meaningful ones like product variants in the cache key.
One of the most important concepts I picked up designing and building Formula SAE racecars in college was systems thinking. A team could easily have "the best engine" or "the best suspension" or "the best controls" and get beat in ...
Dynamic Resource Allocation (DRA) has fundamentally changed how platform administrators handle hardware accelerators and specialized resources in Kubernetes. In the v1.36 release, DRA continues to mature, bringing a wave of feature graduations, critical usability improvements, and new capabilities that extend ...
Chrome 148 shipped this week, and in the release notes you’ll find one of the best things to happen to web performance in a long time: loading="lazy" for <video> and <audio> elements. Scott Jehl, an engineer at Squarespace focusing on ...
When OpenAI trained GPT-3, they didn't roll their own orchestration layer. They used Ray, an open source Python framework born out of the same Berkeley research lab lineage that gave us Apache Spark. And here's the twist: Ray was originally ...
As Kubernetes clusters grow to tens of thousands of nodes, controllers that watch high-cardinality resources like Pods face a scaling wall. Every replica of a horizontally scaled controller receives the full stream of events from the API server, paying the ...
You might know that I – with the generous help from Brandon Kelly on the Craft 5 version – wrote and maintain a Webmention plugin for Craft CMS. Today, I shipped version 1.3.0. It’s a security and abuse hardening release, ...
The cheapest way to learn is to learn from others, so I always take a day every week to see what other organizations are doing and how they are doing
Agentic engineering is the future. But it's still unclear which harness will win, if any. I've been hedging my bets by moving to a harness-agnostic system for AI skills so no matter the harness I use,...
Excel for your logs. Pipe in anything, wrangle it into columns.
In Kubernetes v1.36, Declarative Validation for Kubernetes native types has reached General Availability (GA). For users, this means more reliable, predictable, and better-documented APIs. By moving to a declarative model, the project also unlocks the future ability to publish validation ...
Forgive me, Reader. It’s been five months since my last vibe check. That’s a lot of ground to cover and it’s not possible to get into everything that happened. Like in real life conversations, instead of telling you how I’m ...
If you've ever tried to enforce a security policy across a fleet of Kubernetes clusters, you've probably run into a frustrating chicken-and-egg problem. Your admission policies are API objects, which means they don't exist until someone creates them, and they ...

I have complex feelings about Generative AI but one area I find myself weirdly bullish on is small language models (SLMs) in the browser which are available in Chrome and Edge behind an experimental flag. I know, I know. I ...
I updated my app todometer after several years of it lying dormant, and it's better than ever!
Kubernetes v1.36 introduces Pod-Level Resource Managers as an alpha feature, bringing a more flexible and powerful resource management model to performance-sensitive workloads.
