Visualize.js: Framework for Embedded Analytics and Reports

Jaspersoft, a new acquisition of TIBCO Software, is an open source software vendor that concentrates in providing products used for Business Intelligence (BI).

TIBCO Software recently released Jaspersoft’s newest product – Jaspersoft 5.6. It includes a new Javascript framework that offers built-in analytics and reports called Visualize.js.

The Jaspersoft group came up with Visualize.js because they envision that analytics “is becoming a core component and differentiator of applications and services” for application developers. There is now an increase growth in embedding analytic functionality, however, it is “too complex or too costly” to implement. Jaspersoft’s solution was to incorporate REST and iFrame approaches in this product. "REST gives you a lot of control, but it's very code-intensive to embed. iFrame is simple, but essentially a dumb terminal window. We give you the best of both worlds. You get the control of REST with the simplicity of iFrames. With just a couple of lines of JavaScript, you can embed pretty much any part of our server.” Karl van den Vergh, Jaspersoft’s Senior Vice President said.

Visualize.js equips your applications with the following features:

    Embed Analytics Anywhere - it has the ability of an analytic server with the control of JavaScript and is available as a cloud service.
    Combine Big Data with Relational Data – Data from MongoDB, Hadoop or Cassandra can be combined with relational data using Visualize.js.
    Powerful Analytic Functions – provides new built-in analytic calculations and functions.

Swift: New Programming Language for Apple

Objective-C is the primary programming language used to develop Mac OS X and iOS applications for the past decades. However, earlier this June, Apple released its new programming language called Swift.

Apple described that writing code with Swift is interactive and fun, the syntax is concise yet expressive, and apps run lightning-fast; Swift code works side-by-side with Objective-C thus ready to use for your next iOS and OS X project – or for addition into your current app.

The following are some of Swift language’s best features:

Modern Programming Language

    Swift is the result of research on programming languages that takes the best features of C and Object-C, removing the restrictions on C compatibility.
    APIs are easy to read and maintain.
    Cleaner codes.
    Managed memory automatically using Automatic Reference Counting (ARC).
    Typing semi-colons is no longer needed.

User-Friendly

    Ideal for new programmers as it uses Playgrounds that show results immediately after typing a line of code which makes writing simple and fun.
    Adopts the readability of Objective-C’s named parameters and the power of Objective-C’s dynamic object model.
    Offer easy access to existing Cocoa frameworks.

Read-Eval-Print-Loop (REPL)

    A built-in interactive version of Swift language is included in Xcode’s debugging console or in Terminal. To evaluate and interact with a running app or see how a newly written code works in a script-like environment, use Swift syntax.

Safe

    Removes all classes of unsafe code.
    Always initialized variables before use.
    Checks arrays and integers for overflow.
    Safe patterns in Swift are adjusted for the Cocoa and Cocoa Touch APIs.

2014’s Best Java Tools and Technologies

In May 2014, ZeroTurnaround, a software company who created JRebel & LiveRebel, released the result of their global survey on 2164 Java professionals for their 5th year in Java development research reports.

The following are the results for The 2014 Leaderboard of Java Tools and Technologies survey, which has a 2.1% sample error:

    82.5% - JUnit : Top testing framework used by developers
    70% - Jenkins : Most used CI Server in the industry
    69% - Git : #1 Version Control technology out there
    67% - Hibernate : the top ORM Framework used
    65% - Java 7 : the industry leader for SE Development
    64% - Maven : Most used build tool in Java
    64% - Nexus : the main repository used by developers
    56% - MongoDB : The NoSQL technology of choice
    55% - FindBugs : most-used Static Code Analysis Tool
    50% - Tomcat : the most popular Application Server
    49% - Java EE 6 : found in the most enterprises
    48% - Eclipse : the IDE used more than any other
    40% - Spring MVC : most commonly used Web Framework
    32% - MySQL : the most popular SQL technology

The top four technologies in which developers are really interested in are as follows:

    58% - Gradle : almost 6 in 10 developers say they want to learn more about build tool.
    49% - IntelliJ IDEA : almost half of developers would rather use IntelliJ than any other IDE
    47% - Scala : 47% choose Scala as their next JVM language
    35% - Java 8 : over 1/3 of developers see getting familiar with Java 8 as their highest priority until 2015

Seventy one percent of the Software Developers (which Java professionals commonly called as) build Web Apps while only 3% voted for creating apps for Mobile. Most of them still use Microsoft Windows (50%) for desktops and Google Android (66%) for mobiles.
