Google App Engine (GAE) is among the most popular cloud application platforms today, offering decent service at a low price point or even for free. Unfortunately, however, its Java environment is also fairly restrictive. This session presents several tips and tricks on how to use top Java EE specs – CDI, JPA, JSF2, and Bean Validation, for instance – within GAE’s restrictive sandbox while still benefiting from the highly scalable environment it provides and maintaining portability to other Java EE containers. It demonstrates how CDI can be used to abstract from GAE’s services and how state-of-the-art testing frameworks such as ShrinkWrap and Arquillian can be made to work with a GAE application.

Ever wondered what your application was doing? Why that specific page was so slow? I've asked myself this question numerous times and always had to change some log level or attach a profiler to get actual feedback on what was going on inside my application. With Spring Insight you can get a nice visual representation of specific parts of your application that you would like to have more information from.

The SQL Server Management Studio (SSMS) continues to fascinate me with it’s immense wealth of features geared towards developer & administrator usability. What’s more amazing is that some features perform multiple useful functions depending upon the...

Originally developed at Facebook, Thrift is now an open source RPC framework thanks to the Apache software project. Thrift can be used "scalable cross-language services development," and works near-seamlessly between C, C++, Cappuccino, Cocoa, Erlang, Go, Haskell, Java, OCaml, Perl, PHP, Python, Ruby, and Smalltalk.

The JavaScript version of Decorator seems different, due to the absence of interfaces. Moreover, using prototypes we can achieve automatically the delegation of methods without boilerplate code.

Everybody's talking about how programming is the skill that we all are going to need. [Except those folks who might feel that most programming could be turned into wizard-like tools. Insert long discussion about Strong AI.]

Extroverts love, and get, attention. But organizations miss out when they fail to cultivate the contributions of introverts, too. Susan Cain, author of Quiet: The Power of Introverts in a World That Can’t Stop Talking, uncovers why, and finds ways for “quiet geniuses” to thrive. Elana Varon interviewed Cain to learn how geeky IT introverts (like, say, us) can cope.

Great talk from Abby the IA. Fresh style, clearly expressed. Can’t wait for the poster she’s making.

JSR 292 introduces a new bytecode instruction invokedynamic but also several new kind of constant pool constants. Which means that most of the tools that parse bytecodes like ASM, BCEL, findbugs or EMMA will need to be updated to be java 7 compatible. EMMA is a code coverage tool, a tool that helps developers to know if their tests cover all the code of the application. While it's not the only code coverage tool available in Java, it's the most popular from my personal experience. In this blog entry, I would like to show how to write a simple code coverage tool indycov that use JSR 292 API to have a runtime overhead close to zero.

Mike Driscoll continues his series on wxPython in this tutorial where he explains how to change the fonts using wx.Font and the widget's SetFont method, allowing you to use wxPython's standard fonts as well as the one's loaded on your machine.

Today we’re going to focus on tying the page off with a footer. I’ve always admired sites that put some thought in to the bottom of their page design. There are certainly times when a footer requires nothing more than some basic contact info and maybe a copyright claim.

Dave Beazley's Chipy talk from January 12, 2012. This is a screen capture taken directly from a laptop with a live audio track. About 50 people were...

I always enjoy watching JS1k, which, if you haven’t heard of it, is a JavaScript competition to make the best demo in under 1KB of code.  It has been running for a few years now, and every time, it gets better and better with cooler demos, more judges and of course better prizes.  This time, the theme of the contest is about love given that Valentines day is coming up soon, and we’ve already got some pretty neat demos.  Here are my favorites so far.  You can expect us to post about more as they come in!

Besides its modular architecture, JBoss AS 7 introduces a simplified configuration model and the ability to manage complex multi-server environments. This presentation will cover the core concepts behind the configuration and management model, with an emphasis on managing and deploying to multiple AS instances as part of a managed domain. Additionally we will look into the detyped API, operation-handlers and how Extensions (Subsystems) actually integrate and interact with the management services.

The benefits of getting to grips with Vim are immense in terms of editing speed and maintaining your “flow” when you’re on a roll, whether writing code, poetry, or prose, but because the learning curve is so steep for a text editor, it’s very easy to retain habits from your time learning the editor that stick with you well into mastery. Because Vim makes you so fast and fluent, it’s especially hard to root these out because you might not even notice them, but it’s worth it. Here I’ll list some of the more common ones.

Database source control is no longer negotiable. Databases are an essential component of many of the applications we build and to deny them the value of VCS is just crazy talk. Learn how to make a repeatable continuous integration build for your DB.

The first public build of Google Android 4.0 Ice Cream Sandwich is now available for the HP TouchPad. The tablet originally shipped with HP’s webOS software, but hackers have been installing Google Android on the TouchPad for months. Up until recently, only Android 2.3 Gingerbread was available for the tablet, but now the CyanogenMod team has released CyanogenMod 9 Alpha 0 for the TouchPad. It’s based on Android 4.0 and includes Google’s new user interface which is optimized for tablets without physical buttons. It’s a good fit for the TouchPad, which doesn’t have the home, back, and menu buttons found on most earlier Android phones and tablets.

Patrick Dubois, the Godfather of DevOps (and a DZone MVB), has created a few open source tools and one of them, VeeWee, is a tool for building boxes for a few of his favorite tools like Vagrant, KVM, and Virtual Box. In this video you will witness the magic of VeeWee as Dubois sets up a Windows 7 box with VeeWee from scratch.

There is one subject that could be considered the holy grail of front-end development. A subject that most of us fear and dislike, but is still one of the absolute cornerstones of the web today: forms. Be it styling or mark-up, forms remain a fickle element of our job.

I was wondering all my life why the heck we need a marketing and community management droids at our team. We create a kick-ass products that we can sell them via our web-page using 33 lines of HTML code an an Paypal account.

There’s still a lot of confusion over the difference types of managed beans provided in Java EE 6 with EJBs, CDI beans and JSF managed beans all being available. This article aims to clear up some of the differences between the them and define when to use them.

After the install completes click “Close”.

During last semester I was attending Multiprocessor Architectures course, given at Facultad de Informática where I study my Computer Science degree.
