AI Made Development Faster. Testing Needs to Stop Living in Spreadsheets.
AI agents are making software development faster. That is great. But there is a problem I do not think we are talking about enough: testing is not spe…

Why the retry loop is usually the expensive part of agent work
The first failure usually is not the expensive one. The expensive part is what happens after the first failure when the system keeps trying, keeps spe…
Why AI coding agents need a launch layer
The coding got 10x faster. The launching didn't. Point a coding agent at a half-formed idea and it will hand you a working app before your coffee is c…
We get feedback too late
We talk a lot about shipping faster now, but I think the more interesting question is how fast we learn that we are building the wrong thing. Most tea…
LLM reviewers are useful, but some PR checks should stay deterministic
AI coding agents are getting better at opening pull requests. That changes the review problem. A normal review asks whether the code looks correct, wh…
SpaceX Is Buying Cursor for $60B: What Developers Should Know Right Now
SpaceX has agreed to acquire Anysphere, the company behind Cursor, for $60 billion in stock. The deal was announced June 16, 2026, days after SpaceX's…
I built a macOS notch workspace for local AI coding agents
I have been running more local AI coding agents lately: Codex, Claude Code, Gemini CLI, Cursor Agent, and a few terminal-heavy workflows. The useful p…

Even Anthropic didn't notice Claude got worse for weeks — AI quality is invisible, and that's the enterprise problem
The company that ships the best coding model on the planet just published a postmortem worth sitting with: three innocent-looking config changes quiet…
Building M31A: A Terminal-Native AI Coding Agent That Ships, Not Just Suggests
Most AI coding assistants are glorified autocomplete on steroids. They suggest code, maybe write a function or two, but leave you holding the bag when…
How I debug RAG failures with deterministic signals
When building LLM apps, one frustrating problem is that a response can be wrong for many different reasons. The model may have hallucinated. The retri…
APX Routines Are Deterministic Pipelines Around AI
APX Routines Are Deterministic Pipelines Around AI A lot of agent automation fails because everything is treated like a prompt. The model gets a vague…
wayback-video: Turn Any Site's History into a Video
Side project outside my usual PHP world, but worth sharing. I have a habit of Googling old websites just to see what they looked like. GitHub circa 20…
The MCP Server Pre-Publish Checklist
Before you publish an MCP server, run 10 checks. Most servers fail at least three — and the failures are invisible until an agent picks the wrong tool…
I built an AI code reviewer as a GitHub Action — here's what I learned
If you've spent time on software engineering teams, you know pull request reviews are the ultimate bottleneck. They're slow, inconsistent, and often s…
Your README lies. So I built a bot that opens a docs PR every time you merge.
The README lies. Not on purpose. It was true the day someone wrote it. Then the function got renamed, the flag got removed, the env var changed, the e…
Your README is a landing page: a 10-minute adoption audit for developer tools
For many developer tools, the GitHub README is the landing page. A potential user often decides whether to try the product before visiting a separate …
How to give Claude (or Cursor) access to your Rails app's activity logs
Ask Claude this, today, with no setup: "What did user 4421 do in our app yesterday?" You will get an answer. It will be confident, specific, and compl…
I Tried BrowserAct: A Browser Runtime Built for AI Agents
In my last browser automation article, I wrote about a simple idea: Your browser already has a remote control. Chrome exposes the Chrome DevTools Prot…
The End of the US Cloud Monopoly: AI Balkanization Is Here to Stay
By Vilius Vystartas | June 2026 The single, globally unified internet is gone. What's replacing it is a patchwork of sovereign AI zones, each running …
I built an MCP server that gives AI coding assistants persistent memory (85.6% token reduction)
Every time you start a new Claude Code session, your AI has zero context about what you were working on. Same with Cursor, Cline, Windsurf. You spend …
I Built a Full Apex IDE Inside a Chrome Extension (No Java, No Local Setup)
The Problem with the Existing Apex Workflow If you've done any meaningful Apex development, you know the drill: Open Salesforce Developer Console (slo…
Two unrelated Claude Code Opus 4.8 failures hit the same week: token burn and fabricated tool results
In late May 2026, operators running Claude Code on Opus 4.8 ( claude-opus-4-8 ) filed two structurally different failures within the same few days. On…
Where Claude Code Tokens Actually Go (and How to Cut the Waste)
If your Claude Code API bill feels high, the cause is rarely too many turns. It is a handful of measurable patterns: re-reading the same files, oversi…
The Coding Agent Wrapper Is the Product Now
The model is no longer the most interesting part of a coding agent setup. That sounds wrong if you only watch demos. The demo is always about the mode…
A Fluent LLM Answer Is Not the Same as an Inspected Answer
