Plenty of experienced RPG programmers reach a point where the permanent job no longer feels like the best fit. Maybe the company is stuck on old …
This week I am helping a client migrate their trusty old AS/400 to a shiny brand-new Power System in the Cloud – disclaimer “they call it an AS400, not me” 😉 This glorious old machine has been quietly running IBM-i V7R1, unattended in the corner of a darkened office for a decade. The system admin …
VPN, in plain English A VPN is a private tunnel across the public internet. Think of the internet as a busy high street. Without a VPN, your staff walk that street carrying the company keys.

I am in the middle of helping a client lift a physical Power System out of the computer room and onto a cloud IBM i partition. Same workloads. Same legacy ERP system (RPG, CL and AS400 style physical files) that have paid the bills for years. The transition should be seamless to the end users. …

On IBM i systems, password expiration is one of those security features that works brilliantly for …
Mapepire, a type of pit viper native to South America, is IBM’s new interface layer for IBM-i. Mapepire 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 …
