The new HTTP method : QUERY

16 days ago

You work with REST APIs? You know GET, POST, PUT, DELETE... But did you know that a new HTTP method was standardized in June 2026? It's called QUERY and it solves a problem developers have been working around for 16 years. It's the first new standard HTTP method since PATCH (2010). Yes, you read th

7 New JavaScript Features (And 2 I'm Still Waiting For)

Remember how I promised you (or rather myself) two weeks ago that from now on I'd only write light, easy posts? Well… I broke that promise 😅 Last week I published a huge article about one of the least sexy topics imaginable: legacy applications. Somehow, despite that, the DEV editorial team liked i

Stop Making Your AI Coding Agent Grep Your Whole Repo — Try codebase-memory-mcp

23 days ago

If you use an AI coding agent — Claude Code, Codex CLI, Gemini CLI, Cursor, Zed, Aider, whatever — you've probably watched it burn through tens of thousands of tokens just trying to figure out who calls a function or where a route is defined. It greps, it reads files, it greps again, it reads more f

Building an agentic PR reviewer with Antigravity SDK

25 days ago

As announced in this blog post on June 18, 2026, Gemini CLI and Gemini Code Assist IDE extensions will stop serving requests for Google AI Pro and Ultra, as well as those using it free of charge using Gemini Code Assist for individuals. Google is unifying its AI terminal tools by transitioning the c

The most popular AI coding skills right now

Introduction It's crazy to me that some GitHub repos, that were just created in the last year, have more stars then some of the most popular programming frameworks out there. At the time of writing, Superpowers, is around 226,000, ahead of the Vue repo and way ahead of Next.js. A separate repo bas

Run GLM-5.2 Locally: The Open Model Nobody Can Ban

On June 9, Anthropic shipped Claude Fable 5 — the most capable coding model the industry had ever seen. Three days later, the U.S. government ordered it offline for every user on Earth. No warning. No transition period. One directive, and the frontier vanished overnight. 📖 Read the full version wit

My daughter asked if developers used to write code by hand, but it was the follow-up question tha...

My daughter, who's 11, has been doing some vibe coding. The other day she looked over my shoulder at my IDE and asked: "Dad, was there ever a time when a developer had to write each one of those characters by hand?" "Yes. Twelve months ago." "But... how did you know what to write?" Which was a weir

Headroom: Cut Your LLM Token Usage by Up to 95% Without Changing Your Answers

If you're building AI agents or running LLM pipelines in production, you already know the pain: tool outputs, logs, RAG chunks, and conversation history pile up fast. Before you know it, you're burning through tokens at a rate that makes your billing dashboard uncomfortable to look at. Headroom is a

PewDiePie built an open-source AI workspace, and the point is bigger than the hype

PewDiePie launching an open-source AI project sounds like one of those internet headlines you have to read twice. But it is real. Felix Kjellberg, better known as PewDiePie, has released a project called Odysseus through the GitHub account pewdiepie-archdaemon. The repo describes it as a self-hosted

MarkItDown: Microsoft's Tool for Converting Almost Anything to Markdown

If you've been building LLM-powered applications, you've likely run into the same problem: your data lives in PDFs, Word documents, Excel sheets, and PowerPoint decks — but your AI pipeline expects clean text. Copy-pasting doesn't scale, and most conversion tools either strip too much structure or p

Free Model Providers to Use with Hermes Agent

Hermes Agent by NousResearch is an open-source AI agent that does something most frameworks do not: it learns from experience. It creates skills during use, refines its memory across sessions, and supports parallel subagents and a built-in cron scheduler. You can run it on a $5 VPS, a GPU cluster, o

Antigravity CLI: A Hands-On Guide to Google's Terminal Coding Agent

The AI coding agent space has been reshuffling fast. Anthropic has Claude Code, OpenAI has Codex CLI, xAI has Grok CLI, and now Google has retired Gemini CLI and replaced it with something bigger: Antigravity CLI, a Go-based terminal agent that shares its engine with the Antigravity 2.0 desktop appl

Open Source Toolkit for Building AI Agents in 2026

It used to take a lot of effort to get your first PR merged in open source. Now you can ship something real in a weekend thanks to coding agents like Claude Code. But that also means the noise went way up. I saw the wave of openclaw repos a while back but the ratio of hype to actual maintenance is q

I Tested 6 AI Plans to Find What $5, $10 and $20 Get You

This post was originally published on my Substack publication as I Tested 6 AI Plans to Find What $5, $10 and $20 Get You. A little while ago, I built a multi-step workflow in Hermes to generate a ten-page report that would get stronger each time it passed through the document. It checked the latest

Understand Anything: Turn Any Codebase Into an Interactive Knowledge Graph

You join a new team. The codebase has 200,000 lines of code, no docs worth reading, and the one engineer who knew everything just left. Where do you start? That exact problem is what Understand Anything was built to solve. It is an open-source plugin (15k+ GitHub stars as of May 2026) that scans you

How I Cut My Claude Code Token Usage by 60% and Got Better Output

The first sign something was wrong was the invoice. Not catastrophically wrong. More like “this escalated quietly while I was having fun” wrong. I’d been using Claude Code the way most people start: throw everything at it, stay in the session, keep talking. It felt productive. It was productive. And

CodeGraph: Stop Your AI Agent From Grepping the Same Files 50 Times

When Claude Code explores a codebase it does not know, it spawns Explore agents that scan files with grep, glob, and Read. Every one of those calls costs tokens and time. And most of that work is not even useful analysis. It is discovery: figuring out where things live before the agent can start rea

Graphify + code-review-graph: Build a Self-Updating Knowledge Graph for Claude Code and other AI ...

Every developer working with LLMs on a large codebase eventually hits the same wall: context windows are finite, but codebases are not. You start a new AI coding session, ask about the payment flow — and your agent starts re-reading dozens of files just to get oriented. Twenty thousand tokens evapor

How to Enable Windows K2 Performance Boost on Windows 11
