The MCP part is still early but already lets you chat with your local Confluence mirror in AI coding tools. Feedback very welcome.

Indexer gives you controllable hybrid retrieval instead of black-box API search.

Go stack for local Confluence knowledge: Crawler → clean Markdown mirror Indexer → local hybrid search MCP server Local-first, readable files, offline capable. Still experimental but already useful. github.com/gkoos/confluen… github.com/gkoos/confluen… github.com/gkoos/confluen…

The happy path is not where production systems get interesting. New post on network boundaries, timeouts, retries, idempotency, and what to do when "no response" doesn't mean "nothing happened": blog.gaborkoos.com/posts/2026-07-… #SoftwareEngineering #DistributedSystems

console.log() feels like a point-in-time snapshot of your program, but DevTools often optimizes for speed and interactivity instead. I wrote about the traps and what to use instead: blog.gaborkoos.com/posts/2026-06-… #JavaScript #Debugging #DevTools

Welcome to my newsletter, Import Chaos open.substack.com/pub/gaborkoos/…

The fetch-kit ecosystem now has a home: fetchkit.org Overviews, examples, and comparison tables for @fetchkit/ffetch, chaos-fetch, chaos-proxy, and the live chaos arena - all in one place. fetchkit.org #JavaScript #TypeScript #WebDev #OpenSource

Quick note on confluence2md: ditched the Confluence Storage Format XML and switched to ADF (Atlassian Document Format) JSON from the v2 API instead. Typed AST, no unbound namespace chaos, easier to traverse and render correctly. github.com/gkoos/confluen… #devtools #confluence

npm/Yarn/pnpm/Bun/Deno compared by dependency model and failure mode. #JavaScript #NodeJS blog.gaborkoos.com/posts/2026-06-…

npm package due diligence in 2026: provenance, maintainer signals, and transitive risk. Practical checklist: blog.gaborkoos.com/posts/2026-05-… #npm #AppSec

Just shipped confluence2md, a CLI that crawls your Confluence space and converts it to local Markdown files. Great for RAG pipelines, offline docs, Git-versioned knowledge bases: github.com/gkoos/confluen… #golang #devtools #confluence #RAG #productivity

A nice surprise this week: my article "Your Recursion Is Lying to You" was featured in Node Weekly: nodeweekly.com/issues/624 Thanks to Peter Cooper and the Cooperpress team for including it.

JavaScript has no reliable tail call optimization. You write a tail-recursive function, it looks correct, and it still blows the stack in Chrome, Firefox, and Node. Here is why and what to do instead. #JavaScript #WebDev blog.gaborkoos.com/posts/2026-05-…

Go compiler deep dive + flags: -m, GOSSAFUNC, -S. blog.gaborkoos.com/posts/2026-05-… #Go #Compiler

Your HTTP client can look "resilient" while quietly hurting users. I ran controlled chaos tests on retries, Retry-After, and hedging. In one run, retries reduced errors but nearly doubled p95/p99. Data + setups: blog.gaborkoos.com/posts/2026-04-… #JavaScript #WebPerf

Building a thing: replay real API incidents and tune client retry/circuit behavior to see how outcomes change. Browser-based sim using ffetch + chaos-fetch concepts. Very WIP, but the core loop works. Feedback welcome. fetch-kit.github.io/network-chaos-… github.com/fetch-kit/netw…
