In my Neovim article, I mentioned a tool named tmux. Let’s have a look. tmux is essential for remote development, at least for me. SSH connection drops? Long-running jobs? tmux keeps your session running. This article presents my working tmux configuration, which I use daily at Beta Systems Software AG. Why tmux? If you’re working … Read more
After my three-part VIM series, several readers asked: “What about Neovim?” Good question – and one I’ve been exploring myself. Neovim offers some compelling advantages: Lua configuration, built-in LSP support since version 0.11, and a more modern plugin ecosystem. The challenge? Getting it to work on z/OS with its unique constraints. This article presents my … Read more
In Part 1, we built a solid foundation. In Part 2, we added essential plugins. Now we’re adding the final piece: IDE-level intelligence. By the end of this article, you’ll have auto-completion, go-to-definition, real-time error checking, and code actions, all inside VIM. The same features that make VS Code popular, running in your terminal on … Read more
In Part 1, we built a solid ~150 line VIM configuration. No plugins, just core settings we understand. Now? We add superpowers. By the end of this article, you’ll have fuzzy finding, Git integration, beautiful colors, smart editing helpers, and a status line that actually looks good. All tested on z/OS. All explained. All yours … Read more
Understanding every setting, building incrementally, making it yours. In my previous article, we set up a modern Unix environment on z/OS. Let’s build a VIM configuration that actually makes sense. No copying mysterious snippets from the internet. No cargo-culting settings you don’t understand. We’ll build this step by step, and I’ll explain why each setting … Read more
Your first steps towards feeling at home on the mainframe. When you’re coming from Linux or any Unix-like system, the first encounter with z/OS can feel… different. Yes, it’s powerful, rock-solid, and built to run some of the world’s most important workloads. But when you SSH into UNIX System Services (USS) for the first time, … Read more

But my journey started long before that—back in my spare time, exploring retro operating systems like MVS 3.8j. What began as … Read more
