ArticlesHashes and How to Create Them on z/OS
January 10, 2022

ArticlesThe History of Business Computing Part 1: Counting the Benefits
December 20, 2021
How did we go from the joy of the freedom that personal, commodity computing brought us, to unidimensional cynicism about industrial-strength computing, valuing everything by gross costs without a consideration of the nature and amount of what was being delivered? For that matter, how did we get to a place where requests for proposals (RFPs) […]

First created in 2001, JavaScript Object Notation (JSON) has become the preferred way of creating structured data. Not limited to JavaScript applications, JSON formats can be found in web requests and responses and NoSQL databases.

ArticlesMainframe Connectivity: What’s Missing?
June 21, 2021
We can, perhaps, all remember a time when a simple 3270 terminal emulator was all we needed to access the mainframe without needing a directly-connected terminal.
