Artificial intelligence is no longer limited to large data centers and high-powered servers. Today, more organizations are deploying ML models to edge devices such as smartphones, tablets, and IoT hardware. These devices work in environments where connectivity is not guaranteed and computing resources are restricted. By running models directly on edge hardware, businesses reduce latency, enable offline functionality, and improve ... Read More The post Deploying ML Models to Edge Devices with ...| Keyhole Software
Remember when blockchain was going to change everything? Now AI is the trend dominating every conversation—but some of the most effective programming ideas have been around for decades. This post examines one of COBOL’s lesser-known yet highly practical features: the 88-level field. Far more than a simple boolean, 88-level fields provide a clear, maintainable way to describe data conditions, enforce business rules, and streamline initialization. Through real-world examples, you’ll see h...| Keyhole Software

It’s common to face challenges around long-running workflows, state management, and resiliency when you’re building cloud-native applications. Traditional approaches like background services or message queues might work sometimes, but they often require a lot of “glue code” and custom retry logic. This entails not only more work up-front for the developer, but also more maintenance in the long run. That’s where Azure Durable Functions come in.
