34 Commits of Chaos: DayTrader, AIX, and Knowing When to Pivot

Previously, on “Man Yells at POWER8” In Part 1, I told you about the time I decided to run AIX 7.2 inside a KVM VM on a Gentoo ppc64le host, on actual IBM POWER8 hardware, in my basement in Chicago. I monkey-patched Python 2.7’s sqlitecachec.py to make yum work. I nuked my entire system by installing OpenSSL 3.5 instead of 3.0. I got WebSphere Liberty running and deployed IBM’s DayTrader 7 — a Java EE benchmark app from 2005 that speaks EJBs, JPA, JMS, and looks like it was designed by someone who thought JSP framesets were the pinnacle of web technology. ...

From Concept to Execution: My DevOps Journey with Harvester and Salt

Disclaimer: Opinions expressed here are my own, fueled by late-night coding sessions and an unreasonable amount of coffee.
