rapidBOOKS
LP is a new digital publishing house that produces technology and
management books, research papers, articles and white papers on unique
technology solutions for programmers, software developers, IT Managers
and other IT professionals. rapidBOOKS is the publishing arm of
DexPro(Dextrus Prosoft Inc.), a technology consulting firm that Manoj
Khanna brought to Calgary, Alberta from the Silicon Valley a few years
ago.
“Sometimes it simply takes too long to have a book printed and
shipped, and sometimes the information requires substantial updates
quite soon after publication – particularly in the technology area.
rapidBOOKS LP will address both these with an agile publishing model.”
says Manoj Khanna, Founder & Publisher of rapidBOOKS LP. Manoj’s
vision for rapidBOOKS is to be a digital publishing company that is
fast and agile in responding to the information needs of technology
professionals, particularly in the areas of open source, emerging
technologies and social technology.
rapidBOOKS LP advisor Ron Murch, from the University of Calgary
Executive MBA program, says, “The rate of change, particularly with
technology, computing and telecommunications based tools, is rapid. If
you are at the forefront of that, being able to access current
technical knowledge for problem solving and implementing solutions
becomes quite important. In addition to publishing digital books,
various social media tools are being used by rapidBOOKS to build online
communities to provide easy access to the resources (technology,
information, people) needed to solve these technical problems rapidly.
Set to launch on June 15 with their first set of end of Spring
release titles, rapidBOOKS and its authors from across the globe will
begin with seven books in PDF, Sony Reader, Kindle, iPad, and other
popular formats that the majority of book readers in the market today
use. rapidBOOKS LP will publish books in English, Portuguese and French.
rapidBooks has three series:
- rapidBOOK Series
is a line of full-sized textbooks covering the latest tech topics. The
first in this series is Professional and Scientific Writing with Open
Source Tools and KDE for the Graphical User.
- rapidLearning Series
is a line of quick, easy-to-absorb condensed books on hot tech topics
like Practical & Applied Search Engine Optimization and Practical
& Applied Blogging.
- rapidManagement Series is a line of textbooks on tech management. The first in the series is Practical Agile Experience.
rapidBOOKS also assists other book publishers by converting their
works into digital formats and handling their digital distribution on a
turnkey and project-by-project basis.
The rapidBOOKS team also includes Lyn Cadence, Director Marketing & PR; Audra Gorgiev, Editor; and Shirley Bays, Editor.
For further information or to arrange an interview with Manoj Khanna, please contact Lyn Cadence, Marketing & PR Director at

Our next meeting will be held online, courtesy of Elluminate Live,
between 5pm and 7pm MST on January 13th and will be given by Victor Grazi, Vice President of Global Application Development
at Credit Suisse. Victor has been delivering real-time valuation,
reporting, and trading systems to major financial institutions for over
20 years. He is a Java evangelist and has presented at JavaOne, Java
SIG's, and is a regular presenter at Credit Suisse IT Expos. In this talk we will use animation to visually explore the
building blocks of concurrency offered in the java.util.concurrent
package. At the heart of the talk is a series of animations that
clearly visualize the functionality and timing aspects of each
concurrent component. Each animation features buttons that correspond
to the method calls associated with that component. Each click of a
method button activates a concurrent thread to call that method. The
audience will watch how the threads interact with each other in
real-time as they contend for access to some blocking structure, as we
talk through salient features of the component.
Components covered include,
- Executors
- Semaphore
- Future
- Reentrant Lock
- ReadWriteLock
- Condition
- BlockingQueue
- CyclicBarrier
- CountDownLatch
- CompletionService
- Compare & Swap
Each animation is controlled by the actual Java concurrent
component it is illustrating. So the animation is not only a visual
demonstration, it is also a code example. So if you’re still using constructs like Thread.start or
wait/notify, you will want to attend this meeting. You will need to download the animations prior to the meeting. They are packaged as an executable JAR file and can be downloaded from http://sourceforge.net/projects/javaconcurrenta/. To join the meeting, you must have Java 5 or later installed and be prepared for the Elluminate Live client to download. JOIN THE MEETING (Link valid from 4.30PM MST January 13th). |

Our next meeting will be held online, courtesy of Elluminate Live, between 5pm and 7pm MST on November 11th. Our speaker will be Alex Miller of Terracotta who will be talking about "Scaling Your Cache and Caching At Scale". Caching has been an essential strategy for greater performance in
computing since the beginning of the field. Nearly all applications
have data access patterns that make caching an attractive technique,
but caching also has hidden trade-offs related to concurrency, memory
usage, and latency.
As we build larger distributed systems, caching continues to be
a critical technique for building scalable, high-throughput,
low-latency applications. Large systems tend to magnify the caching
trade-offs and have created new approaches to distributed caching.
There are unique challenges in testing systems like these as well.
Ehcache and Terracotta provide a unique way to start with simple
caching for a small system and grow that system over time with a
consistent API while maintaining low-latency, high-throughput caching.
Alex Miller is a Tech Lead with Terracotta Inc, the makers of the
open-source Java clustering product Terracotta. Prior to Terracotta, Alex
worked at BEA Systems and was Chief Architect at MetaMatrix. His interests
include Java, concurrency, distributed systems, languages, and software design.
Alex enjoys tweeting as @puredanger and blogging at http://tech.puredanger.com.
In St. Louis, Alex is the founder of the Lambda Lounge group for the study of
functional and dynamic languages and the Strange Loop developer conference.
