Introducing Crypts and Commits

The Audience I Didn't Know I Had β€” Part One There is a lot of conversation right now about one developer coordinating forty coding agents. I am not going to pretend I know whether that is good or bad. It is clearly a real model of working, and there are people doing remarkable things with it. But I keep coming back to a more ordinary question: what does agentic development look like for a team of ten developers, each working with one or two agents, while still staying in sync with one ano...

Tab is whitespace, so your TSV parser is not one

TSV is the format shell speaks. jq -r @tsv , git for-each-ref --format , ps --format , anything piped into awk -F'\t' β€” when a shell script needs columns, it gets tabs. And the canonical way to read them back is one line everybody has written: IFS = $' \t ' read -r a b c That line does not read TSV. It reads something else that looks exactly like TSV until a column is empty , and then it hands you the wrong value in a variable with the right name. Every ...

Most Kubernetes clusters can't tell you what their GPUs cost

I built a small tool to answer one question: how many GPU-hours is a cluster paying for and not using? Then I pointed it at real production clusters. Not one of them could answer the question out of the box and the reasons are the same everywhere, because they're all defaults nobody changes. Here's what I found, in the order it bit me. 1. The utilization metric everyone reports doesn't mean what you think Almost every GPU dashboard is built on DCGM_FI_DEV_GPU_UTIL . It's ...

We paid real USDC 1,596 times to x402 endpoints. 653 settled.

x402 is the HTTP 402 payment protocol: a server answers 402 Payment Required with the price and the address, the client pays, and the request goes through. Coinbase's Bazaar catalog now lists tens of thousands of these endpoints. The protocol proves that money moved. It does not prove that anything was delivered. We have been buying from that catalog with real money to find out what actually happens after the payment. Here are the numbers as of 2026-08-26, straight from our public sta...

.NET 10 BufferedStream WriteByte: Flush Full Buffers Explicitly

BufferedStream.WriteByte had a surprising side effect through .NET 9: the call at its internal capacity boundary also called Flush() on the wrapped stream. The .NET 10 BufferedStream WriteByte behavior removes that implicit flush. Bytes can still move to the underlying stream when the buffer needs room, but that capacity boundary no longer becomes an accidental flush boundary. That distinction matters when a custom stream, protocol adapter, compressor, or test double gives Flush() obse...

Let AI Write the Mac OS App Without Learning Swift

AI keeps accelerating through the tech industry. Just like many other laid-off tech workers, I feel little miserable how far has AI really affected companies to minimize or eliminate junior to mid level software engineers. Starting last year I've been using the basics of premium GitHub plan with various versions of Claude Code, Gemini, and GPT, to generate bare bones of applications and components, use auto-inspect-and-suggest coding segments, and ask technical questions about certain issues i...

My AI Agent Recommended a Non-Existent Investment Product β€” Exposing Information Gaps Between Fund Distributors and Asset Manage

Hey everyone, it's your average 38-year-old developer here, hacking away at AI agents and automated trading bots in my evenings and weekends, just like many of you. Today, I want to share a recent blunder with a financial information AI agent I built. What started as a chuckle-worthy mistake turned into a serious lesson about "information reliability" β€” a critical factor that can be fatal for any automated system design. The Problem: AI Recommends a "Non-Existent Investment Trust...

An Agent on a Leash, or why my AI agent doesn't make business decisions

This post kicks off an ongoing experiment: building an LLM-powered support agent you can actually trust, one decision at a time. Everything described here ships in the companion repo reliable-ai-support ( code as of this post: tag post-001 ), which grows as the series does. Where I mention future topics, read them as current intentions, not contracts β€” the whole point of building in public is that the plan bends to what actually works. The Support-Agent Problem Picture...

Node.js Express Observability: A Beginner's Health Endpoint-to-Uptime Signal Contract

Short answer: for a flagged fintech pricing change, use an external uptime monitor to test whether the public path is reachable, then use an internal dashboard to decide whether the new rule is healthy enough to keep enabled. The important design choice isn't dashboard versus monitor. It is giving each signal one failure meaning, so a valid 422 pricing rejection never wakes someone up as if the Node.js service were down. Pick this signal Pick it when Let it decide Do not ask it...

Show HN: TeXbrain, a LaTeX editor that runs pdfTeX in the browser via WASM

I'm a master's engineering student and a big fan of LaTeX, which I used for my thesis and research articles. I have used Overleaf and that was fine until I wanted to git sync, which unfortunately sits behind a paywall. Since I didn't want to pay subscriptions for things that should simply just work, I built the editor I wanted in my free time, where you open a tab, write LaTeX, get your PDF and the files stay all in one folder on my disk. TeXbrain is a static site with no backend. pdfTeX is comp...
