One String to Rule Them All
String literals are quite a common feature in most code—from error messages, to exception text, to trace data, to prompts and informational text—it’s rare to find a significant span of code that doesn’t contain string literals. JavaScript is, of course, no exception and historically a JavaScript coder had two options for string literals: putting them […]

Modern Assembler Programming for z/OS
When I started at Rocket in 2003, I was migrating from a 20-year career as an MVS Systems Programmer who dabbled in writing assembler tools to a fully-fledged software engineer. At the time, the style of assembler that I used and the tools at my disposal were based on what had been in existence for […]

Five things from yesteryear that have still “got it”
Nostalgia, or “a sentimental longing or wistful affection for a period in the past,” is a common occurrence in adulthood and has never been as visible as it is today. Think about hipster-culture—bringing back old game consoles like the Nintendo 64, and shunning Spotify in favor of vinyl (it just sounds better). While initially, users […]
IBM Z and Hybrid Cloud: The Best of Both Worlds
It’s impossible to say what the biggest change in computing has been over the last decade, but certainly one of the most significant shifts has been the adoption of the cloud. For the first time, organizations have freedom of choice to deploy applications and data virtually anywhere in the world, giving them unprecedented flexibility in […]
FinTech, Mainframes and Open Source: The Perfect Trio
It’s not an exaggeration to say that everyone who works in the financial sector interacts with a mainframe at some point during their day. That may be surprising to most people, but the reality is that banking is dominated by large, powerful computers that can provide unprecedented security while making billions of calculations a day. […]
Open Sesame!
It’s not exactly news to anyone that Rocket loves the IBM mainframe. Same goes for me. I started my career working on mainframe computers, and for nearly three decades I’ve run Rocket with the goal of solving hard, technical problems for IBM mainframe customers. I’ve seen a lot of changes over the years, but in […]
The Mainframe is Now Open
Today is a big day. Not just for Rocket, but for everyone in the global mainframe community. A few hours ago we announced the launch of Zowe (pronounced ZOH-ee), the first-ever open community for z/OS. This is a joint effort between three major players in the mainframe space – IBM, CA and Rocket – as […]
Terminal emulator licensing doesn’t have to hurt
Licensing used to be a pretty simple thing: companies would pay for a certain number of seats and then install the software. This worked pretty well for many decades. And then the cloud happened – and all the rules changed. After all, without software hosted on-site there’s no simple buy it/install it model anymore. So […]
