Roland Hughes is the president of Logikal Solutions, a business applications consulting firm specializing in VMS platforms. Hughes serves as a lead consultant with over two decades of experience using computers and operating systems originally created by Digital Equipment Corporation (now owned by Hewlett-Packard).
With a degree in Computer Information Systems, the author's experience is focused on OpenVMS systems across a variety of diverse industries including heavy equipment manufacturing, pharmaceuticals, stock exchanges, tax accounting, and hardware value-added resellers, to name a few. Working throughout these industries has strengthened the author's unique skill set and given him a broad perspective on the role and value of OpenVMS in industry.
Mr. Hughes' technical skill sets include the following tools that enable him to master and improve OpenVMS applications: DEC/VAX C, DEC/VAX C++, DEC BASIC, DCL, ACMS, MQ Series, DEC COBOL, RDB, POWERHOUSE, SQL, CMS/MMS, Oracle 8i, FORTRAN, FMS, and Java, among others. Being fluent in so many technical languages enables Hughes to share his knowledge more easily with other programmers.
What if the Mayans got the start of the end correct because they had survived it once before? What if our written history was just as accurate as the old tale about three blind men describing an elephant? What if classic science fiction writing and television shows each got a piece of it correct, would you know which ones? If your eyes can only see a tiny portion of a collage do you know it is a collage?
Fans of Babylon 5, Star Trek TNG, Battle Star
Galactica (the new one) and classic science fiction
writing will enjoy the bountiful Easter Egg hunt
contained within. When you were a child you learned to
connect paper clips or thread beads together to make a
necklace. Sit back and watch the beads you have had
all your life form the picture you could not see.
Consider for one second the possibility of the story,
then hang onto your mind with both hands while you
take the ride.
BOOK THREE IN THIS SERIES
Lesedi - in his country his name means 'the light' though he has never chosen to walk in it. A man who has been driven by duty to himself now finds he must carry out one final duty for a country which isn't even his. He has finally learned the meaning of a phrase he had uttered much of his life "sucks to be you."
This book is both stand alone and the middle work of the “Earth That Was” trilogy. “Infinite Exposure” and “John Smith - Last Known Survivor of the Microsoft Wars” are the beginning and end. It was written in response to fans wanting a bit more of “the story in between.”
The first wave of nuclear attacks from both terrorists and governments has happened though the general public has yet to figure it out, most are too busy trying to survive to bother figuring it out. The predicted extinction of all life did not happen possibly because many of the first attack detonations occurred at our own nuclear power plants.
Follow his journey and those of the survivors he meets along the way to see if the Universe allows them a brief bit of happiness or chooses to squash them like a bug.
BOOK TWO IN THIS SERIES
An espionage novel written in 2008, the author has predicted stories that are now in today’s news headlines! This heavily researched work of fiction was written shortly after 9/11 and long before identity theft or data breaches were in the news. Read and decide for yourself which is scarier, what it says is coming or how much it has already gotten right?
This work of fiction uses historical information and relevant news stories to draw a line from post 9/11 through the off-shoring of IT jobs and the largest terrorist strike the free world has ever known to the resulting nuclear war.
That, however, is not the interesting part of the story. How we got there is a far more interesting tale indeed. Follow the story from post 9/11 to where it all went bad and see if you can find a way out, not just for yourself, but for everyone.
BOOK ONE IN THIS SERIES
The Minimum You Need to Know Series...
Rather than focus on the front end, this book focuses on the back end. That Heritage data silo/application where all of the other books just draw a box with “connect somehow” written on it. Most of them try to sell some expensive middleware along the way.
Management can and should read the first 5 chapters in this book. These chapters aren't technical and may very well open their eyes. The remaining chapters are for those programmers given the “connect somehow” task. While OpenVMS is the Heritage platform of choice in this book and Ubuntu is used for the front end development, developers from other platforms should get a lot of ideas by reading this book.
Source code is provided on the CD.
This book is part of "The Minimum You Need to Know" family of books by Logikal Solutions. As the family expands they will cover an increasing variety of topics. This book is designed to be used as a test book for classes in logic from high school to college level. It should be one of the first books you read when starting in IT.
Not only does this book cover flow charting and pseudocode, it teaches the reader to think before they start mapping out the logic to solve a problem. The author of this book is an industry veteran with roughly 30 years in the field. It has been his experience that recent graduates, from any country, are nearly useless at problem solving. If they cannot point, click, and drag, they cannot solve the problem. This book is an attempt to teach them how to solve the problem.
There are two main intents of this book. The first intent is to allow developers who know at least one of the covered languages on another platform to quickly come up to speed on the OpenVMS platform. The second is to assist current OpenVMS developers finding themselves having to work with a different language their current language become productive.
A single application is developed over and over again in each of the languages. Both RMS Indexed file development and relational development are covered in the book. When working with MySQL only the C language is covered. The accompanying CD-ROM contains the source code developed in the book. By being able to compare the source code for the same application in different languages the reader can quickly get a feeling for the design trade offs and benefits of each language covered.
The screen handler covered is FMS. While this may be one of the oldest if not the oldest screen handling/forms development packages on OpenVMS it also has a very large base in production systems. If you are new to the OpenVMS environment you will encounter it. Once you know this forms management system you should be able to quickly pick up the other products on this platform.
This book is meant to provide a much needed tutorial for the OpenSource xBaseJ library. If you have some fundamental Java skills this book can have you developing your own xBaseJ applications in a matter of hours. The xBaseJ library was used by the author to create the FuelSurcharge project on SourceForge.
Most books on Java drop you immediately into developing Web applets and HTML pages. This book doesn't bother covering what is done in thousands of other books on the market. Here we focus on using JNI to access RMS (Records Management System) indexed files and FMS (Forms Management System.) You will learn how to use Java with MMS (Module Management System) and CMS (Code Management System.) Finally, the same application found in The Minimum You Need to Know to Be an OpenVMS Application Developer is redeveloped using Java with FMS and RDB (Releational DataBase.)
In short, this isn't just another “oatmeal for the masses” Java book. It is for professionals on the OpenVMS platform who find they must now work with Java.
