·1 views

A Kafka Connect task failed on October 8, 2026, after a system reboot for a kernel patch. The failure occurred because the JVM's temporary directory, set to /var/tmp/kafka, was deleted. The system's service configuration lacked instructions to recreate this directory upon restart. The missing directory prevented the ZSTD compression library from initializing, halting data processing.

They advise validating the core idea through prototypes or experiments before full development. The article stresses that product distribution and user discovery must begin early and are integral to building. Finally, it recommends starting with a deliberately narrow solution and measuring progress by user outcomes, not code volume.

MCP Cassette tool enables offline testing of AI agents by recording and replaying server sessions

The mcp-cassette tool records live Model Context Protocol server interactions into a JSONL file. This recording can then be replayed as a standalone MCP server for offline testing. The approach eliminates dependency on live servers, credentials, and network availability during testing. The tool also includes safety checks for potential security risks in tool contracts. It supports multiple testing frameworks and integrates with CI/CD pipelines.

Security experts advocate Least Privilege principle to limit app permissions

The Principle of Least Privilege advises granting users, applications, and services only the minimum permissions necessary to perform their specific tasks. This approach, aligned with NIST guidelines, is a security measure to limit potential damage if credentials are compromised. For example, a service generating sales reports should only have read access to relevant data, not permissions to update or delete records. Security best practices also require enforcing these permission checks at the backend API level, not just the user interface.
