Building a High-Performance Fan Speed & Temperature Manager with C# and .NET

Hello, I'm Dr. Jhonatan. I recently published an open-source Windows Forms application built with C# / .NET designed for real-time hardware temperature monitoring and dynamic PWM fan speed control: Cooler Speed Change & Management.

Dr. Jhonatan has unveiled an open-source Windows Forms application designed to monitor and control fan speeds, called Cooler Speed Change & Management. The application offers several key features, including real-time monitoring of CPU and GPU core temperatures, dynamic PWM fan control with individual selection and manual adjustment for compatible cooling fans, and low overhead thanks to async/await and background tasks (Task.Run) that ensure precise telemetry with no UI freezing and minimal CPU usage.

Powered by LibreHardwareMonitor, which utilizes robust low-level hardware APIs, the application boasts multi-language support, with the UI available in English, Spanish, Portuguese, Japanese, Korean, German, Italian, French, and Simplified Chinese. The source code, along with releases and documentation, can be found on GitHub: https://github.com/drJhonatan00/Cooler_Speed_Change_and_Management. Dr. Jhonatan encourages users to star the repository, test the software, and contribute feedback.

Failed Webhook Backoff and DLQ Redrive for 3 Marketplace Deadline Guarantees

Short answer: A marketplace renewal reminder should enter the dead-letter queue when another attempt cannot finish before its business deadline; use at-least-once delivery, a stable idempotency key…

  • Marketplace reminders must meet deadlines or go to dead-letter queue.
  • Exponential backoff with jitter prevents synchronized failure waves.
  • Idempotent delivery IDs ensure safe at-least-once processing.

Idempotency for Reliable APIs

Why idempotency matters When you build an API, retries are inevitable. Clients lose connections, timeouts happen, and users double-click buttons.

  • Idempotency prevents duplicate actions and side effects in APIs
  • HTTP GET, PUT, DELETE are inherently idempotent while POST isn't
  • POST idempotency achieved via unique Idempotency-Key header

Architecting a Low-Power GPS Geofencing Engine for Android Background Services

The atmosphere in the room was dense, the kind where every whisper echoes. I was sitting in the third row of a local community center during a Friday prayer session, my head bowed in reflection.

  • Architect designed low-power GPS geofencing engine for Android background services.
  • Implemented ForegroundService to bypass Android Doze mode reliability issues.
  • Prioritized battery efficiency over accuracy with 50-meter geofence variance.

Why I Built a Browser Extension for WhatsApp Web

I did not start building MSG.AI because I had discovered a grand new AI opportunity. It began with a much smaller problem—one that kept repeating every day. A message arrives in another language.

  • MSG.AI extension integrates directly into WhatsApp Web to streamline translation and messaging.
  • Prioritizes data privacy and security through local storage and authorized AI processing.
