When Your Electron App Needs a Real Shell, Not Just a Webview
I've built countless Electron apps, and the boilerplate fatigue is real.

When Your Frontend Needs a Dedicated CPU: Offloading to Web Workers with Comlink
You've got a complex calculation, an intensive image manipulation, or maybe just a really big data transformation. You throw it into an async function, sprinkle in an 'await', and hope for the best. But when that 'best' still means a janky UI and frustrated users, it's time to give that heavy liftin
n8n: Beyond Zapier, Workflow Automation That Actually Runs How You Want It
We've all used tools like Zapier or IFTTT to glue services together. They're great for simple tasks, but as soon as you need something a bit more complex – custom logic, self-hosting, or deeper integration – you hit a wall. That's where n8n comes in, offering a powerful, open-source alternative for
