Proxmox cluster formed cleanly but its heartbeat ran over the management network

0
·1 views

A three-node Proxmox cluster appeared healthy and reported quorum after creation and joining. On closer inspection, one node's corosync cluster heartbeat was using its management interface instead of the intended server network, because the join command had no flag to pin the link address. The setup worked only because the management network happened to route to the other nodes, leaving a latent risk. Such a problem could have caused a node to fence and reboot if that network were firewalled or disrupted. The author fixed it by editing the corosync configuration, correcting the ring address, incrementing the config version, and restarting corosync node by node while quorum was maintained.

Open-source MCP server flags malformed Search Console API requests before Google returns silent empty results

Google's Search Console API often returns empty results without any error when a request is invalid, such as an unsupported country code, a non-RE2 regex, or a date range in the future. This makes it hard to distinguish a broken query from a genuinely quiet period, and AI assistants can mistakenly explain the empty output. The developer built open-gsc-mcp, an MIT-licensed local Model Context Protocol server that validates requests before calling the API and reports problems in plain language. The tool also offers change-explanation and indexing-audit features, and it is read-only by default with no telemetry.

Protecting a Customer-Support LLM Agent from PII Leaks With Logging and Masking

A tutorial describes how to secure an LLM-based customer-support assistant for an e-commerce service like Cdiscount, which can look up orders, issue refunds, and send emails. It warns that attackers could use prompt injection or tool abuse to make the agent exfiltrate customer personal data. The proposed defense is ReskPoints, an AI agent logger that records each action with its confidence, parameters, and results. The tool automatically masks sensitive fields such as tokens, passwords, and contact details before logs leave the application. It also supports sampling rules to limit log volume while keeping full visibility into tool calls, and can export traces to platforms like Datadog, Prometheus, or OpenTelemetry.

206 Sign-in Starts, Zero Signups: Checking Whether AI Visitors Really Convert

A founder saw 206 sign-in starts and no completed signups in a week, which seemed to point to a broken auth flow. The real cause was bot-like traffic: about 190 of 205 Google sign-in clicks in four days came from Germany, many with impossible browser and OS combinations. After filtering that traffic out, weekly visitors fell from 358 to about 85 and sign-in starts fell from 206 to one. The author argues that AI referral traffic should be judged by downstream conversion, starting with removing junk data before computing any rates. The method also covers building an AI-assistant segment using both referrer and utm_source fields, since most ChatGPT visits in one founder's data arrived with no referrer.

7 CSS Myths Beginners Should Stop Believing

Beginners learning CSS often receive advice that is incomplete or simply wrong, which can lead to confusion and frustration. A common misconception is that developers must memorize every property, when the more practical skill is understanding core concepts and looking up details as needed. Another myth holds that CSS only changes colours, while in reality it governs layout, spacing, typography, sizing, positioning, responsiveness, and animation. The article also argues that good CSS is not defined by using many visual effects, but by applying styles with a clear purpose that supports clarity and usability.
