Remember when blockchain was going to change everything? Now AI is the trend dominating every conversationโbut some of the most effective programming ideas have been around for decades. This post examines one of COBOLโs 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, youโll see how this feature can reduce complexity, eliminate hard-coded values, and make logic more expressiveโdemonstrating that sometimes proven tools from โoldโ languages still have lessons worth applying today.
Outdated deployment practices can slow down even the best software teams. When youโre still manually moving files between servers, itโs easy for small mistakes to slip through and updates to take longer than they should. At Keyhole Software, weโve seen firsthand how this approach can hold back your projects. The solution is to automate deployment pipelines. It brings consistency, reliability, …
In this post, weโll explore how to use GitHub Copilot to generate Java code and unit tests with minimal manual input.
