Lint Prompts to Avoid Wasting Free Model Calls

The article describes a developer's experience of repeatedly consuming free-model calls in CI due to an ambiguous prompt. The author recommends treating prompts as versioned contracts and running a fast, static linter that checks for required sections (role, constraints, output_format), forbids vague phrases, and enforces length limits before any model call. A Python example linter and GitLab CI job are provided; an alternative thin HTTP endpoint is suggested for shared runners. The approach reduces wasted quota and CI time but does not replace human review or domain-specific validation.

• The author observed three repeated free-model calls on the same commit caused by an ambiguous prompt.
• They implemented a static prompt contract linter (Python) that checks for required sections, forbids ambiguous phrases, and enforces prompt length.
• The linter is intended to run in GitLab CI before any model call; a sample GitLab CI job is provided.

Install Apache Kafka 4.2 on Ubuntu WSL2 (KRaft)

This technical guide explains how to install and run Apache Kafka 4.2 in KRaft (Kafka Raft Metadata) mode on Ubuntu 24.04 running under WSL2. It covers prerequisites (Java 11+), downloading and extracting Kafka, configuring server.properties for a single-node broker+controller, initializing KRaft metadata (generating a Cluster ID and running kafka-storage.sh format), starting the broker, creating/listing/describing topics, producing and consuming messages, and common administrative commands and troubleshooting. The author highlights the removal of ZooKeeper in favor of KRaft, the importance of the controller.quorum.voters setting, and the two-listener port model (9092 for clients, 9093 for internal controller communication).

• The guide installs Apache Kafka 4.2 on Ubuntu 24.04.4 LTS running in WSL2 using KRaft mode (no ZooKeeper).
• KRaft mode uses an internal Raft-based Controller to manage metadata; a unique Cluster ID must be generated and kafka-storage.sh format must be run once before starting the broker.
• Example server.properties for a single-node KRaft deployment includes process.roles=broker,controller; node.id=1; controller.quorum.voters=1@localhost:9093; and listeners for PLAINTEXT on 9092 and CONTROLLER on 9093.
