Ensuring your computer is up-to-date is the mantra of anyone in IT, one not everybody follows when it comes to themselves. As it seems, when we exit college, we're fed up with learning, dismissing any critique on our professional or academic ambitions with a simple "I'll be fine, I'm not stupid". This dismissal might lead up to serious neglect. ...
Over the past 4 years, Spring took a step back and JEE got much of the spotlight in the world of Java. Something that I embraced for several reasons, but Spring wasn't actually gone, it just got slightly misplaced. ...
After having not done any updates for about a year and a half, my PC was for from up-to-date and even further from up-to-date-able. My portage tree was nothing less than a mess, using overlays that weren't updated in ages. With in the end not being able to print on my brand-new printer, being the final problem to get me to fix it. ...
There's a lot of talk about DevOps, presented as though it's very new and something we've yet to get any experience with, this most definitely is not the case. First of all, let's identify what we're talking about. Strictly limiting our scope to DevOps, Development and Operations, the core principle is bringing together Development and Operations, providing a single team with a mandate to deliver their software. Something we can indeed consider new in the world of enterprise development, a place with great solitary towers on great solitary islands. Development and Operations are often so distant from another in this world, that it requires someone with a tie to intervene when the two try to work together. On the other hand, companies whose purpose in life it is to deliver a product are left gawking in awe at the whole DevOps discussion, wondering what has happened to make their way of working so special. ...
Lucene is the an embeddable search engine used in many (many...) Java applications. It's extremely powerful, flexible and configurable. Exactly this makes it perfect to embed. Although you have to watch closely how you use it. ...
A little background CDI has had a major influence in the Java community. It's inclusion into JEE6 has greatly improved the way of working with JEE in general, this itself caused a major leap in adoption of JEE. So far so, that it's being applied indiscriminately, something I'm not much of a fan of. For most of the web applications being built, CDI is a great tool to accelerate implementation. ...
One of the essential properties of object oriented programming is the encapsulation of an object state. The most important side effect of this encapsulation is that an objects' state is exposed through its methods. These methods allows for various guarantees, such as class invariants and method invariants. ...
Traditionally, a structure of a set of Maven projects is rather treelike. With a direct symmetrical module parent relation. Also, the parent POM then tends to hold many dependencies which are often only relevant to a subset of modules. This approach is outdated and tends to be a maintenance and development nightmare. Especially when more than one person develops on it. ...
Perhaps a disclaimer first, I haven’t found this in textbook, although I wouldn’t be surprised if it were. It’s actually an explanation I used on a job to explain how splitting responsibilities would help them in their DTAP environment. It’s a loosely defined way of looking at some responsibilities of some facets with respect to testing and deployment. ...
In the world of open source, Java comes quite naturally. There are the quite significant Apache and Eclipse foundations, along with the very many smaller open source contributions. But this makes Java a bit of a hammer for very many nails. Personally, I like working with Java. But sometimes I see Java being applied where it perhaps shouldn't. ...
