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.

One thing always leads to another! In my house (and home office), I had an ASUS RT-AC68U router (on main floor) and a Tenda W150M router (in basement). Once in a while, someone would complain that the ‘internet is not working’ or ‘internet sucks’! Sometimes it would be as simple as being on the wrong […]
