Node.js Security on IBM i: Don’t Twist Your Melon (But Do Pay Attention)

A subscriber left a great comment on one of my recent vlogs. They’re worried that all this Node.js stuff IBM is encouraging means we’re opening up security holes. npm had that supply chain mess with Red Hat back in 2024, and now hundreds of packages with their own dependencies are sitting on our systems. Is IBM i suddenly less secure? Are we giving attackers a bigger target in what used to be a pretty locked-down world?...

So, what exactly is IBM-i Mapepire?

Mapepire, a type of pit viper native to South America, boasts a logo that’s arguably the best creation from Big Blue since the original IBM emblem. As for how to say it, IBM-i Mapepire GitHub says Mapepire is pronounced ‘mapəpɪə’ or ‘MAH-pup-ee’ which seems nonsense to me! I've been pronouncing this as Mape (like V**e) Pire…...

Rogue Rules Files are Twisting My Melon Man!

TOBi Builder MAKEi Fails with BLEUUURGH Error Code - A Quick Debugging Tale Hey there, fellow IBM i programmers. Today we're diving into a real-world head-scratcher I hit while working with TOBi (the IBM i Object Builder) and its MAKEi component. If you've ever tried to compile from your local source copies and instead of the usual nice "X programs compiled, Y failed" summary, you got a horrible mess of Python script errors, "failed to download a file", "no such file", or some equally unhelpful BLEUUURGH, then this one's for you....

Debugging RPG with IBM BOB

DISCLAIMER: This is not my usual style of programming video. It's long format, lots of me muttering at the camera while trying to fix some RPG code. I started recording with no idea if it would work or not. Spoiler - it did in the end. Also featuring an AI generated video, a growling version of me with fantastically lunatic hair....

IBM i ACS 5250 – It’s time to talk about Blurry Fonts

Why do IBM i ACS 5250 characters suddenly look like they’re auditioning for a modern art exhibit whenever Font Scaling is enabled? If you fire up Access Client Solutions on a modern high resolution monitor and find yourself squinting at blurry text in your 5250 sessions, you are not alone.

I think we all know that AI the Future of IBM i Development? Well, I reckon AI is absolutely going to be a big part of the future for IBM i development, but it is not going to wave a magic wand over decades of fixed-format RPG and turn everything into shiny free-format perfection overnight. Tools like IBM BOB are already showing real promise by helping us refactor legacy code, explain what that cryptic subroutine is actually doing, and handle the boring repetitive tasks…...
