Why most traceability matrices die — and how to keep one living

I used to think a traceability matrix was a table you updated before a certification audit and then forgot about until the next one. After five years of MDR audits, Technical File updates and more than one surprise notified-body question, I no longer believe that. A traceability matrix that "lives" is not a spreadsheet with cell comments. It is a connected, reviewable artefact of your quality syst...

Sigstore Deep Dive: Unmasking the Magic Behind Keyless Verification

Introduction In my previous article, "Supply Chain Security: A Deep Dive into SBOM and Code Signing," we took Cosign's keyless signing for a spin. You run cosign sign, your browser pops up, you log in with GitHub, and boom—your container image is signed. No private key management. The moment the signing is done, the key is thrown away into the void. It was insanely convenient. But hone...

Make It Easy to Work Hard

If working hard feels harder than it should, the problem may not be you. Sometimes the real problem is how the work is set up. Early in your career, “working hard” often sounds like a character trait. Some people grind. Some people push through. Some people seem able to focus endlessly. So when you struggle to start, drift midway, or avoid coming back after a break, it’s easy to assume somethin...

Memory management in Claude Code: Context Pipeline

If you are building an AI agent that needs to survive longer sessions, context management becomes a systems problem very quickly. At first, the implementation looks simple. You append messages, keep tool outputs around, maybe summarize occasionally, and keep going. But once the session becomes longer, the same problems start showing up: prompts get too large, tool outputs dominate the context, ...

The 3 isTrusted:false Bugs That Made LinkedIn Posts Impossible From My MCP Server

TL;DR I couldn't post to LinkedIn from my MCP server. Not "sometimes fails" — never works. I assumed one bug. I was wrong. I found three, stacked, and each one looked like success to every automation tool I tried. Here is the anatomy of why your agent's "I posted it!" lies to you when a rich-text editor sits inside a dialog. The symptom I ship Safari MCP — an MCP server t...
