How I Built a Privacy-First “Image to PDF” Converter using JavaScript (Zero Server Uploads)

34+ min ago   (342+ words) Why you should stop uploading your personal documents to random converter websites and how to build your own client-side alternative. If you do a quick Google search, you will find thousands of free “Image to PDF” converters. But there is…...

Your remote MCP server is "connected" and still returns 401

15+ min ago   (523+ words) There is a specific kind of bug report that shows up in every remote MCP rollout, and it always sounds the same: I added the server. It shows as connected. It lists tools. Then the first real call fails with…...

MCP Servers: The Plugin System AI Agents Were Missing

6+ min ago   (116+ words) Every AI framework reinvented the same wheel: how to let a model call tools. LangChain had its format, OpenAI had another, Anthropic had yet another. Then MCP (Model Context Protocol) arrived. It's doing for AI agents what USB did for…...

The failing probe proves your checker is alive. It does not prove it can see.

6+ min ago   (922+ words) This week someone published a gate that is supposed to run an AI agent's tests outside the tree the agent just edited — reject any diff that touches tests/, run pytest, pass only on exit code 0. Then they took their own…...

Merkle Trees vs Hash Chains for Audit Logs: A Practical Decision Guide

6+ min ago   (571+ words) If you're building an audit log and want it tamper-evident, you'll hit the same fork I did: do I link records in a sequential hash chain, or build a Merkle tree? Both let a third party detect tampering, but they make…...

The remote MCP client config matrix nobody documents (and the three ways type fails silently)

14+ min ago   (496+ words) I maintain a remote MCP server that authenticates with a static Authorization: Bearer header. No OAuth, no device flow, no browser handoff. That is the boring case, and it turned out to be the one where every client has its…...

Trusted Timestamps (RFC 3161): How to Anchor a Hash Chain So No One Can Rewrite the Past

7+ min ago   (714+ words) A hash chain proves a record was not modified after it was written. It does not prove when it was written, and it does nothing against someone who controls the server and can re-sign the whole chain. RFC 3161 trusted timestamps…...

Your approval gate can be worth less than no gate. The variable is not the reviewer.

12+ min ago   (455+ words) You have a gate. An agent proposes, a human approves, the action runs. The argument for it is airtight as far as it goes: a gate can only add a rejection opportunity, so more escalation and a better reviewer can…...
