My name is Roger Lacroix and I am a die hard programmer. I have been programming since the 80s. My favorite programming languages are Java, C and Rexx. I have worked in the Airline, Retail but I have spent most of my time doing middleware work in the financial services industry. In 1994, I was introduced to IBM MQ (aka WebSphere MQ & MQSeries) and I thought it was the next best thing since man created fire. This blog will be about IBM MQ, Java, C, Rexx and any other interesting items that I can think of. I hope you enjoy it.

I’m sure lots of people will read the title and say WTF!?! What have you been using? I’ve been using Window 7 Pro since late 2011. Since Microsoft’s support of Windows 7 will end in January 2020, I figured it was time to move on. My ASUS ZenBook 13.3″ and desktop PC still work reasonable […]
