  • Tech Tip: Be Like a Turtle!

    Especially in the open source world, people talk about shells a lot. Instructions to “run this command in a shell” are standard fare. But, what is a shell? Simply put, a shell is a command processor. It is a program that takes input from the user and runs the appropriate commands. Conceptually, it is much like the CL entry screen you’ve used in 5250. Rather than running CL commands from the QSYS.LIB filesystem, it runs executable binaries from a hierarchical file system (stream files from the QOpenSys or root filesystems on IBM i). This includes things like open source language runtimes, common shell commands (ls, cd, pwd, cp), or any PASE executable (most open source). The best way to access a shell on IBM i is from an SSH client.

    Let’s Learn About Ublu

    Have you heard about Ublu? It’s a programming language created specifically for IBM i tasks. That notion alone makes for an exciting story! On top of that, the language runtime is now an open-source project, which adds a level of “cool.” It also happens to be a very useful language. You can see why I chose to put a spotlight on this technology today: It’s a useful, cool invention built for IBM i!

    A Tale of Two Web Servers

    It was the best of times, it was the first of times. At least, it was the first time I announced a new open source delivery in a COMMON session! In a crowded room in Orlando, I declared a fresh addition to 5733-OPS: the nginx web server, to be delivered into option 11 of the product.

    One Small Program, Two Powerful Messages

    To further explain the value of open source, I wanted to highlight a small, open-source Python program. It shows active connections, much like the “netstat” command on other platforms. In all, the program and its implementation are both pretty simple.
