Java.net App Hosting

Hong Zhang's Blog mentions that java.net is now hosting J2EE applications for free through LocalWeb. Here's the quote that scares me:

> The actual deployment of an application is done by a small team of engineers from Sun.

Yikes. Even with all the deployment descriptors, it takes "a small team" to host and deploy a single J2EE application. There's something wrong with that.

I've always said that deploying Java applications is Java's Achilles Heel. The LAMP community mocks Java not necessarily because the language is more verbose, but because it's so dang hard to deploy the applications. Compare with PHP, which is as easy as editing the file and then hitting reload in your browser. That's nearly impossible with a full J2EE application. So many libraries have memory leaks that play havoc with classloaders that a full application server restart is required.

In any case, this is one of the main reasons I've been moving to Rails. I can deploy an application in no time (especially when using SwitchTower).

Lists and arrays in Dart

(This is Part 3 in a series about Dart. Check out Part 2, Function in Dart .) Warning : We expect the Dart libraries to undergo potentially sweeping changes before Dart goes to alpha. This document is relevant as of 2011-12-22. Intro Dart is a "batteries included" effort to help app developers build modern web apps. An important "battery" is the bundled core Dart libraries, providing common and rich functionality. Dart is building a solution for large, complex web apps, and providing well tested, integrated, and common libraries is key to helping a web app developer be more productive out of the box. The Collection libraries are a crucial set of APIs that Dart developers get for free. Much more than simple arrays and maps, the Collection library includes standard ways to filter, iterate, inspect, compose, and sort your data. This post specifically looks at List<E> , Dart's ordered, indexable collection of objects. Aside: The Dart project is lucky...

Converting Array to List in Scala

Now, this has to have a built-in somewhere in Scala , because it just seems too common. So, how to convert an Array to a List in Scala? Why do I need this? I needed to drop to Java for some functionality, which in this case returns an Array. I wanted to get that Array into a List to practice my functional programming skillz. **Update**: I figured out how to convert Arrays to Lists the Scala way. Turns out it's a piece of cake. val myList = List.fromArray(Array("one", "two", "three")) or val myList = Array("one","two","three").elements.toList The call to elements returns an Iterator , and from there you can convert to a List via toList . Nice. Because my first version wasn't actually tail recursive, what follows is a true tail recursive solution, if I were to implement this by hand. The above, built in mechanism is much better, though. object ArrayUtil { def toList[a](array: Array[a]): List[a] = { d...
