Internet of Things Wearables: New Buzz or New Technology? | @ThingsExpo [#IoT]

JDJ - 3 hours 4 min ago
About 15 years ago I fainted. It was the only time in my life that I fainted. The reasons were probably, blood donation a day before, Work from 7:00 until 19:00 and participation in the the thirty-third day of the Omer period ceremonies of my children (I stood for a long time beside the traditional fire). No problem found during The Medical Check up, I performed. The Medical Check up included wearing an Holter Monitor recording my heart activity for 24 hours. The Holter was a Wearable computing device, however nobody used the word Wearable. If we exclude the enhanced computing power of current Wearables in comparison to the old Holter monitor, we can find two factor differentiating current Wearables from the Holter Monitor.

In-Memory Computing By @GridGain | @CloudExpo [#BigData]

JDJ - 8 hours 34 min ago
In the last year, conversations about In-Memory Computing (IMC) have become more and more prevalent in enterprise IT circles, especially with organizations feeling the pressure to process massive quantities of data at the speed that is now being demanded by the Internet. The hype around IMC is justified: tasks that once took hours to execute are streamlined down to seconds by moving the computation and data from disk, directly to RAM. Through this simple adjustment, analytics are happening in real-time, and applications (as well as the development of applications) are working at-pace with this new standard of technology and speed. Despite becoming both more cost-effective and accepted within enterprise computing, there are still a small handful of falsehoods that confuse even the most technical of individuals in enterprise IT.

Programmer Knowledge

Java Lobby Announcements - 10 hours 34 min ago
What is the half-life of programmer knowledge? It is quite common with claims that the half-life is something like 5 years. In other words, half of what you know about programming will be obsolete in 5 years. A similar sentiment is: “Programming sucks, because what you knew a few years ago is useless now”.At first, this seems plausible. After all, there is a steady stream of new...

Creating the New Big Data Developer By @ABridgwater | @CloudExpo [#BigData]

JDJ - 13 hours 4 min ago
HP hasn’t exactly coined the term Big Data developer. Except, perhaps, it maybe kind of has if you look at the recent tools being rolled out from the firm’s HP Software division. All working towards what HP loves to call “business transformation” – the company is now also using the term “new style of IT,” by which it of course means cloud-centric (always hybrid) technology architectures aligned to take advantage of Big Data analytics (even in SMBs) and other more cutting-edge elements such as enterprise social activity and collaboration technology.

Performance Matters, Benchmarking Saves By @CliQrTech | @CloudExpo [#Cloud]

JDJ - Wed, 2014-12-24 18:00
Comparing cloud providers is complicated. With constant price drops and the frequent introduction of new instance types, no matter what answer you come up with today it is sure to change in three months. Taking into account differences in performance, it gets even more confusing when you realize that applications run differently on different clouds. One thing is certain though: price in a vacuum doesn’t tell you the whole story. In fact, it’s a lot like selecting a car based on sticker price and assuming the fuel efficiency of the cylinders is equal across manufacturers. It’s not.

Really Too Bad that Java 8 Doesn't Have Iterable.stream()

In-Memory Database vs. In-Memory Data Grid By @GridGain | @CloudExpo [#BigData]

JDJ - Wed, 2014-12-24 00:30
I'll explain the difference between two major categories in in-memory computing: In-Memory Database and In-Memory Data Grid. A few months ago, I spoke at the conference where I explained the difference between caching and an in-memory data grid. Today, having realized that many people are also looking to better understand the difference between two major categories in in-memory computing: In-Memory Database and In-Memory Data Grid, I am sharing the succinct version of my thinking on this topic - thanks to a recent analyst call that helped to put everything in place

So You Want to Use JSON with 'Internet of Things' | @ThingsExpo [#IoT]

JDJ - Tue, 2014-12-23 21:30
Here is a comprehensive article on the basics of using JSON, the Javascript Object Notation. JSON packs lot more power into just information in a piece of text. JSON has become a nice connector to bridge the physical (IoT) and the Digital worlds (Web Services). Get this still in development plug-in (pURL) if you want to read URLs in JSON format to send out a listenable event. This is just the beginning to create automatons based on URL content, be it web services or something else.

Aggressive Decoupling of Scrum Teams

What does aggressive decoupling look like? Last post I talked about the failure modes of Scrum and SAFe and how the inability to encapsulate the entire value stream will inevitably result in dependencies that will kill your agile organization.

ORM Is an Offensive Anti-Pattern

Java Lobby Announcements - Tue, 2014-12-23 09:00
TL;DR ORM is a terrible anti-pattern that violates all principles of object-oriented programming, tearing objects apart and turning them into dumb and passive data bags. There is no excuse for ORM existence in any application, be it a small web app or an enterprise-size system with thousands of tables and CRUD manipulations on them. What is the alternative? SQL-speaking objects. Preview...
