So you need to build a visualization of data that must loaded and interface dynamically. Good looks are important so you chose JavaFX but you are starting from an existing Swing based application. No problem right?
But what if you have a lot of data to load into your Scene? How do you maintain a positive User Experience?
Maybe you are using the NetBeans Platform because... well...

What are the cost vs. benefits of creating interfaces and how should they be balanced? I am only considering cases where interfaces are optional and aren’t needed.
Simplify interaction: Easier to see how to use a List than an ArrayList
Make testing easier because replacement implementations can be used
Can make future changes easier
Harder to understand what the code is doing...

Acteur is a pattern for pipelining work - a little DI functional goodness for Java. I might have been speaking Swahili when I wrote about Acteur last month. So here's a simple explanation of the design pattern behind it, with a simple sample project.

As this JavaRanch article by Mark Spritzler proofs, there seem to be some people that like to have a generic visitor pattern, so I decided to open source mine (LGPL), which lies around here on my disk for some time. Have fun using it, it is as simple as linking to:

I hate adding lots of huge multi-JAR all-purpose common libraries to rather small projects! Huge footprint just for a single class is a side effect of many popular frameworks, unfortunately, due to rather coarse-grained modularity. So I started to publish some of my commons (LPGL'ed) code as single-class self-contained artifacts on The Maven Central Repository.
You simple need a Range<T>...

According to Wikipedia, the Knuth-Morris-Pratt algorithm "searches for occurrences of a "word" W within a main "text string" S by employing the observation that when a mismatch occurs, the word itself embodies sufficient information to determine where the next match could begin, thus bypassing re-examination of previously matched characters".
Being 'A' the...

You want JAXB to unmarshal singletons? You already spent lots of time coding rather complex workarounds applying XmlAdapters and afterUnmarshal callbacks? The solution is astonishingly simple. Possibly so simple that nobody in the JAXB team ever thought it would be necessary to put the word "singleton" somewhere next to the JavaDocs for this... Anyways, here is the solution:

Concentrating on Task in Hand (similar to Mylyn) in NetBeans IDE
Often we work on fixing a bug or developing an enhancement for an open source project maintained over a period of many years and having hundreds of source code files. usually we need a handful of 5 to 10 source files to fix the bug or to add new enhancement. The project explorer provided by IDE's like NetBeans IDE show...

In 1996, a group that I was working with devised a development process which we called Defect Driven Design, otherwise known as D3. We were a bit disappointed by not surprised that D3 never really caught on but just recently I saw a glimmer of hope for a revival. It was quite a surprise when about a year ago when Cameron Prudy started telling me about this great methodology called Defect...

Often code has a bad smell, then it gets time to replace custom lines by common patterns. Sometimes it even makes sense to even replace a single line of code by a class just wrapping that single line (which actually increases code size), if that makes readers better understand what the code does. Unfortunately often such patterns are publicly known but do not exist as ready to...
