I am very proud to say the second edition of EJB 3 in Action is now published. In addition to covering EJB 3.2, we've also covered JPA 2.1, CDI 1.1, JAX-RS and WebSocket. The goal is to try to cover as much of the Java EE 7 "backend" technologies as possible.
What my Clojure code is doing most of the time is transforming data. Yet I cannot see the shape of data being transformed – I have to know what the data looks like on the input and hold a mental model of how they change at each step
Technical debts in software are those places where, while the code functions properly, it has internal problems that make it challenging to maintain. As a developer, nothing feels better than tackling a piece of long-standing technical debt and turning code that everyone hates into code that’s a joy to work with.
Make sure you didn't miss anything with this list of the Best of the Week in the DevOps Zone (Apr. 25 to May 1). This week's topic includes test-driven development, continuous delivery, scaling self-service-as-a-service, development methodologies, and Jersey/Jax RS streaming JSON.
Just keep in mind that you don’t push the git repository to some public space since the config files might include a lot of passwords. Also look out for his .gitignore in his case the printer does a lot of automatic changes and is thus ignored. You might have similar settings for your configs.
This post may sound commonplace to you if you already use IntelliJ IDEA. If so, then just ignore it or share with a friend of yours, as it’s intended for people who are still wondering what’s so special about IntelliJ IDEA and why is it so different from other IDEs.
One of Red Deer’s goals has always been for it to be an easy to use test platform, but it’s always lacked the convenience of a keystroke recording tool. Until now that is. Before we look at how we can use the Recorder, let’s take a minute to understand just how it works.
For a dynamic language, it’s more difficult than it needs to be to import a module dynamically in Python. It’s very easy to just from foo import bar, but what if you want to load a list of things and all you have is a string representation of each one, for example foo.bar?
As a company focused on server management, we’ve been talking a lot about how we can help DevOps and IT pros automate tasks and generally make their lives easier. Many a customer have asked us to include scheduling of tasks into our product. So, this past week we just did that!
You can not. This is a lie, just like the cake. You can lower the number of bugs.
The Avail team has announced the first release of Avail, an "articulate programming language," which attempts to offer a somewhat natural expression form for solving programming problems.
ZF2 controllers tend to extend AbstractActionController which does not define a constructor. This means that you can define your own constructor in your controllers and use it to inject the dependencies that your controller needs.
About a year ago I wrote a blog post showing how to stream a HTTP response using Jersey/Jax RS and I recently wanted to do the same thing but this time using JSON.
We’ve all seen industry trends come and go, but DevOps can’t be considered a fad. It’s an approach that has come about as a result of drastic movement in the industry towards automation and the changing role of the IT admin.
Was this OpenSSL vulnerability an oversight by system administrators installing unknown software?
The simple answer is no. OpenSSL is the defacto SSL implementation used on most internet servers around the world. This is not an untested, unverified component that slipped by security audits.
I’ve been using the clj-time library recently – a Clojure wrapper around Joda Time – and one thing I wanted to do is format a date with day suffixes e.g. 1st, 2nd, 3rd.
The Open Session in View (OSIV) pattern gives rise to different opinions in the Java development community. Let's go over OSIV and some of the pros and cons of this pattern.
Shell scripts are a staple in any IT environment. There are quick little scripts for all kinds of little tasks. But, there are also much more complicated scripts to automate critical business processes. If you need to schedule a task or group of tasks, you end up creating a cron job.
I see an interesting parallel in the debate over practices in the running world and practices in the software development world. Indulge me for a moment while I attempt to share my thinking.
Continuous Delivery often challenges conventional wisdom within the IT industry, and by advocating the rapid release of value-add to reduce risk it contradicts the traditional belief that a low release cadence is an effective risk reduction strategy.
At the RSA Conference 2014, we gathered some of the top DevOps experts and influencers at an evening called Wining Not Whining and asked them “Why is application security so important to the DevOps revolution?”
Sirix is a versioning storage system capable of storing and querying snapshots of temporal trees effectively and efficiently. In stark contrast to other database and storage systems Sirix offers advanced versioning at the storage layer and extends high-level APIs as for instance XPath/XQuery.
Below are several development "methodologies" that are popular and even industry-standard
Unless your software is very simple, no single tool or pipeline implementation will provide you with Continuous Delivery. Effective Continuous Delivery requires an organizational understanding of the intent and purposes of the activities you undertake, not merely the automation of those activities.
David H. Hansson (@DHH) sparked the “TDD being dead” latest twitter storm. DHH is no stranger to controversy, and he certainly picked the right title for it. Of course, the responses followed immediately. and most of them fell directly into his...
