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.

Robert X. Cringely has an interesting perspective of the PC era: http://www.cringely.com/2012/06/30/life-personal-computer/ If you extrapolate Robert’s thoughts to other computing environments then you would say: – The mainframe is dead – long gone buried. Oh wait, it lives and is doing very well. – The super-computer is dead. Well, it almost died but with Linux […]
