The JWT Decoder That Proves Most ‘Client-Side’ Tools Are Lying to You

Most JWT decoders ask you to trust they’re ‘client-side’ β€” but trust is not a security property. This decoder uses CSP connect-src ‘none’ to make token exfiltration technically impossible. The security guarantee is in the HTTP headers, verifiable by anyone with DevTools. No promises, no trust β€” just proof.

The One App That Will Replace All Your Hardware Apps (And It’s Already Installed)

Tired of juggling a dozen clunky apps for your smart devices? A new open-source project shows that the web browser can replace them all. PowerScope turns a USB-C power tester into a web app, proving that the universal interface you need is already installedβ€”and it’s time for hardware makers to stop locking you into their ecosystems.

Your Broken Link Isn’t a Bug. It’s the Only Story Worth Telling.

You click a link expecting the world and get a void. When a post titled ‘Travel’ crashes into the mundane reality of a missing URL parameter, the real story isn’t the broken linkβ€”it’s the user comment trying to debug it. Stop treating broken links as technical hiccups; they are profound failures of context where users become impromptu QA engineers.

The Real Innovation Isn’t the 3D Graphics, It’s the 5MB Limit

A developer spent 2.5 years building a fully immersive 3D portfolio website that runs at 60 FPS on a low-end i3 laptopβ€”and fits entirely under 5MB. The real innovation isn’t the 3D graphics, but the meticulous engineering and optimization that makes such a complex experience possible within severe constraints.

Stop Asking AI to Design. Make It Copy Instead.

AI can’t see pixels. It guesses. The fix? Stop asking it to design and start forcing it to copy. A closed-loop feedback system that compares rendered images eliminates UI hallucinations. The future of reliable AI development isn’t better promptsβ€”it’s blind apprentices with constant visual correction.

Stop Spinning Up Local Servers. Firefox Just Made Them Unnecessary.

Firefox Local Mode eliminates the most overlooked friction in modern web development: the mental context switch of spinning up a local server just to preview an HTML file. For developers prototyping with AI tools like Claude and Codex, this feature compresses the gap between code generation and visual validation to near-zero β€” and challenges the assumption that middleware is always necessary.
