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.

You have implemented CHLAUTH and/or CONNAUTH features in IBM MQ. So, give yourself a pat on the back, a gold star or have another cold one on you because you […]

Language Wars – Maybe Enough Already

Maybe I’m just old and grumpy, but I’m tired of surfing the internet and seeing language wars. I just saw this line “100% Java free!” the other day, listed as a product feature and it makes me shake my head. Of all the product features that would sell a product, you want to include that […]
