I Built a Free Image Editor Because I Didn't Want to Pay for an Expensive One

Building an Open-Source Image Editor Because the Alternatives Were Too Expensive When I started integrating image editing into one of my applications, I evaluated several popular image editing libraries. Many of them were excellent. They offered polished UIs, powerful editing capabilities, and years of development behind them. However, I quickly ran into a problem. No single library ...

Four ways a file-sync tool eats your data, and how to not

I've been building a small sync tool — it moves files between a remote project and a local folder, git-style (clone, pull, push, status). The moment you write a tool that touches other people's files on both sides of a network, you inherit a category of bug that's worse than a crash: silently destroying work the user can't get back. Here are four data-loss traps I hit (or nearly hit), each with t...

Stop Validating AI Agents Only at the Start: Introducing Mid-Chain Governance

Modern AI agents rarely complete a task in a single model invocation. Instead, they execute multi-step workflows: Retrieve documents Call APIs Query databases Generate intermediate plans Invoke external tools Produce a final response Most AI safety mechanisms, however, only validate the initial prompt or final output. This leaves an important gap. The Hidden Risk in Multi-Step AI Workflows Im...

Clojure vars - notes

Intro named references (symbol) to values of fn they live in a namespace mutable reference to an immutable value Var is separate from the value so you can redefine it Note: symbol is just name Dig Deeper Functions are actually stored in vars (defn greet [name] (str "hello" name)) ; is equal to (def greet (fn [name] (str "hello" name))) ; because defn is macro ...

LangChain’s tool routing is a bloated mess. So we built a <10ms local semantic registry to replace it at US Neural.

Look, LangChain was great to get the ecosystem started 0 to 1. But let's be honest: taking LangChain to production with 50+ tools is a nightmare of abstraction hell and brittle if/else logic. The AgentExecutor is slow, and relying on it to route complex tools feels like fighting the framework. Tool discovery shouldn't be an LLM's job, and it shouldn't require a heavy python wrapper. It’s a distri...

41 of 78 useEffects in our app shouldnt exist, mostly ai first draft

grepped every useEffect in src last week instead of fixing a form that flickered on load. agents write most of the first drafts here, i review. 78 of them. went through each with the "you might not need an effect" page open. 19 were state derived from props or other state. useState plus an effect that joins two strings. thats a variable. 14 were fetching on mount with a loading and error...

I Built an AI App That Finds What You Can Build With Your Old LEGO Bricks

A few months ago, I was looking at a familiar scene that many parents probably know: A huge box full of LEGO bricks. Thousands of pieces. Different colors, shapes, and sizes. But the funny thing is… nobody knows what can actually be built with them anymore. My kids would open the box, search for a few minutes, and eventually say: "We don't have the right pieces." Then they would ask for a...

We made SigNoz's LLM observability actually reachable…

-and added the one signal it was missing Track 01 — AI & Agent Observability. A hackathon project built from scratch, July 20–26, 2026. There's a sentence we said to each other on day one and then kept saying all week, because it kept being true: An API 200 is not evidence that a feature works. This post is the story of a project that lives entirely inside that sentence. It's about a f...

Openship: Your Deployment Tool Shouldn't Compete With Your App for RAM

The self-hosted PaaS drawer is not empty. Coolify, Dokploy, CapRover, Dokku, Kamal. If you have wanted a Heroku you actually own, someone has already built you three of them. So when Openship showed up in July 2026 and hit several thousand GitHub stars in about a week, the reasonable reaction was skepticism. Another dashboard for docker compose up. Having read through it, there is one architectu...

Linux Isn't Hard—You're Learning It the Wrong Way

Stop memorizing commands. Start understanding concepts. Many people believe Linux is difficult because they begin by trying to memorize dozens of terminal commands. After a few days, they forget most of them and feel discouraged. The truth is simple: Linux isn't hard---you're probably learning it the wrong way. Whether you want to become a Linux administrator, DevOps engineer, cloud engineer,...

I Built a Security Scorer for 213 MCP Servers — Here's What Made the Difference

Every time I wanted to add an MCP server to Claude Desktop or Cursor, I ended up with a dozen browser tabs open, trying to answer one question the README never answers: is this actually safe to give tool-call access to my machine? MCP (Model Context Protocol) directories exist, but most of them just mirror GitHub — stars, a README excerpt, a copy-paste config. None of them score risk. So I built ...

How We Built a Modular Etsy Research Pipeline with Apify

When people think about scraping Etsy, they often imagine a single script that collects everything in one run. That approach works for small experiments, but it quickly becomes difficult to maintain, scale, and reuse. Instead of building one large scraper, we designed our Etsy research pipeline as a collection of small, focused components. Each component performs a single task well, and together...

TokenCap v1.6.0 is now live

One thing I've realized while building with AI is that context isn't a prompt problem anymore. It's an engineering problem. Over the last few weeks I've been using TokenCap on larger projects and found myself repeatedly asking: Why is the AI reading files that don't matter? Why am I sending the same context over and over? Why does every task start from scratch? So v1.6.0 focuses on making co...

I reverse-engineered Claude's undocumented Design API so a file sync wouldn't cost 665k tokens

A build log about protocol archaeology, three wrong guesses, and refusing to trust my own mocks. The token bill that started it Claude Design (claude.ai/design) is a nice place to keep a design system, but the files live there, on the server. The obvious way to get them onto disk is to ask an agent: "read every file in this project and write it locally." That works. On one large projec...
