7 Security Checks Before Installing a New Developer Tool

`Installing a new developer tool can save hours of work, improve productivity, and simplify complex tasks. But every new application, extension, package, or utility also introduces another piece of software that you need to trust. A useful tool can still create problems if it comes from an unofficial source, requests unnecessary permissions, has not been maintained for years, or quietly collects ...

I built a React Markdown editor kernel. The hardest part wasn't handling changes, but deciding what hadn't changed

I recently put the entire editor kernel behind DOMD on GitHub: https://github.com/do-md/domd/tree/main/.packages/%40do-md/core (Quick license note: the app sources are MIT. The kernel is GPL-3.0 with additional permissions for small entities and common FOSS licenses. The full terms are in the repo.) There's one design choice I'd really like to hear other people's thoughts on. A common way to model...

From Python to Go: rewriting a CrewAI workflow in pure stdlib

In the CrewAI Python framework you assemble teams of agents that collaborate via LLMs. It’s a great model when tasks require multiple specialists. But pulling in litellm, langchain, pydantic and friends makes cold starts heavy and deployment a container story. A few months ago I started crewai-go, an idiomatic Go port with zero external dependencies. The whole core package is pure net/http, encod...

A Slow Task Runner Is Not a Dead Task Runner

One line in the n8n 2.35.5 release notes carries a useful lesson for every workflow and agent runtime: task runners should not be restarted merely because they are slow. The distinction sounds obvious, but many recovery loops collapse duration and liveness into the same signal. A job crosses a time threshold, the supervisor assumes it is dead, and the worker is restarted. If the original worker w...

The Reasoning Ledger: Remembering Decisions, Not Just Data

Part 4 of the Building the AI Memory Stack series After finishing the previous article, I looked at the repository a little differently. The specifications were still there. The Architecture Decision Records were still there. The glossary entries were still there. The project's durable memory had done exactly what it was supposed to do: preserve the knowledge that deserved to survive. But someth...

Looking for 100 technical testers: SecondGate (WordPress security & passkeys, no cloud dependency)

We've spent the last few weeks trying to break our own plugin. We fuzzed the WebAuthn decoder with 200,000 adversarial inputs, found a bug where brute-force lockout could silently lock out every legitimate visitor sharing a CDN's IP, and once we went looking, found and fixed six separate places in the codebase making that same mistake. All of it is documented, versioned, and dated: https://secondg...

Why do most color pickers use HSL, but when I change the color of my accent or cursor on Windows 11, it uses HSV? Also, why are both web-safe and X11 colors discouraged, while CSS/HTML colors are widely used?

[Gemini API in Action] Adding a "Detailed Research Report" Button to a LINE Bot: Using Google Search Grounding to Turn Summaries

Background My LINE Bot has always had a summary feature: you drop a URL in, it crawls the content, generates a summary, and attaches a social media post draft along with a button to save it as a bookmark. This feature has been around since 2024, but it has always only solved the "what is this about" problem. I often find myself wanting to know three other things: What is the backgrou...
