| How to Keep Distributed Systems Consistent: Versioning vs Vector Clocks |
| |
| |
| Optimistic locking laughs in the face of traditional locking's sluggishness. It just checks that data remains unchanged before a write—dodging deadlocks and ditching lock overhead like yesterday’s news. Meanwhile, sequential version numbers deliver the knockout punch to timestamps when it comes to maintaining order. They sidestep race conditions and spot missing updates in distributed systems without breaking a sweat. |

| Beyond “5 Whys”: A Better Way to Learn from Incidents |
| |
| |
| The most important purpose of a post-incident review is to learn from incidents and improve the system. The "5 Whys" technique, while intuitive and easy to explain, may have limitations in facilitating meaningful learning from incidents. Open-ended questions in post-incident reviews can lead to richer learning, systemic improvements, and actionable insights. |

| Host remote MCP servers in Azure Container Apps |
| |
| |
| MCP (Model Context Protocol) is shimmying its way into the center stage as the go-to AI communication layer. It’s ditching local servers for cloud-hosted, multi-tenant ones. But the transition isn’t all smooth sailing. It’s wrestling with ever-shifting specs. Right now, remote servers only handle SSE transport and API key authentication. No surprises there. Meanwhile, VS Code is hustling to catch up. |
