How to Fix GBase 8a Metadata Loss After Unclean Cluster Shutdown

·2 views

A sudden power loss or kernel panic in a GBase 8a cluster can prevent in-memory metadata from being written to disk, leaving the gbase.table_distribution system table with missing rows. This causes queries to fail with error GBA-02SC-1001, while the affected table enters a contradictory state where it can neither be dropped nor recreated. The recommended recovery method is to manually insert the missing metadata row directly into gbase.table_distribution, then restart the gcluster service for changes to take effect. Administrators can also identify all affected tables using an information_schema query, or restore data files from a healthy standby cluster if one is available. To prevent recurrence, experts advise maintaining regular backups of the table_distribution table and avoiding abrupt cluster shutdowns wherever possible.

Developer releases lightweight AI agent library with pause, resume, and human approval

A developer has published yieldagent, an open-source JavaScript library for building AI agents in roughly 200 lines of code with no external dependencies. The library implements a standard agent loop — sending messages to a model, executing tool calls, and repeating until a final answer is returned. A key feature is human-in-the-loop support, allowing specific tool calls to be paused for approval before execution, with resumable state that can be serialized and stored. The library is provider-agnostic, supporting any OpenAI-compatible API including Ollama, and offers optional Zod-based tool validation and streaming support. The project is available on npm and GitHub, with a browser-based demo that requires no API key.

How a Repetitive Work Task Led a Non-Programmer to Learn Coding with AI

A non-technical professional who once considered coding inaccessible began learning Google Apps Script after noticing a time-consuming, repetitive data-entry task at work. Using AI as a starting point, they generated code, debugged errors iteratively, and eventually built a working automation. The process introduced them to core programming concepts such as variables, conditions, and triggers through hands-on problem-solving rather than formal study. Despite the help of AI, they found that understanding the code — not just copying it — was essential for maintaining and adapting their scripts. The experience reshaped their view of coding as a practical, learnable skill for anyone looking to improve everyday workflows, not just professional developers.

How a Beginner Used AI Prompts to Build Spreadsheet Automation from Scratch

A self-taught coder discovered the value of automation after growing frustrated with manually managing repetitive spreadsheet tasks such as sending emails and updating statuses. Using AI as a coding assistant, they built a Google Sheets script that automatically sends a confirmation email and logs a timestamp when a row status changes to 'Sent.' Early attempts failed due to vague prompts, but refining instructions with specific column references and conditions produced a working solution. The experience revealed a broader pattern behind automation: a trigger checks a condition and then executes an action. The author concluded that while AI accelerates code generation, understanding, testing, and human judgment remain essential parts of the process.
