Validation in Flex with Hamcrest-AS3

By Joel Hooks
November 20, 2009

Hamcrest? No, it isn't a fancy sandwich topping. Hamcrest is a framework for creating matchers, allowing matching rules to be defined declaratively (from Wikipedia). Hamcrest has been used by many popular unit testing frameworks including JUnit and FlexUnit 4. Hamcrest-AS3...

Using UDP socket connections for low-latency and loss-tolerant scenarios in AIR 2 (Part 3)

By Ian McLean
November 19, 2009

Is There Any Correct Java Code Out There?

By James Elliott
August 5, 2009

Writing correct, concurrent code is really hard. Java makes it seem easier than it is, even when you think you're being careful. The language support is better than it was before Java 5, but we still have a lot to learn. And we have to learn fast, because our code is running on more and more processors every day.

Writing the Pac-Man Game in JavaFX - Part 5

By Haining Henry Zhang
June 12, 2009

In previous articles, we finished writing most of the code of the Pac-Man game. In article 3, we implemented a simple algorithm for the ghosts to catch the Pac-Man. The ghosts randomly decides in which direction they move. They do not chase the Pac-Man even they are very close to him. This makes the game less challenging. In fact, the behavior of the ghosts are the most tricky part of the game. According to Iwatani, the author of the original arcade game, he had designed each ghost with its own distinct personality in order to keep the game from becoming too difficult or boring to play. ( More info) However, there is generally no conclusion on what behavior of the ghosts are good for the players.

Writing the Pac-Man Game in JavaFX - Part 4

By Haining Henry Zhang
June 2, 2009

In the last article, we developed a preliminary version of the Pac-Man game. Four ghosts are randomly roaming the maze and a Pac-Man character can be controlled by a player. Now, we write some more code for the interaction between ghosts and the Pac-Man: Pac-Man eats a ghost after he gobbles a magic dot. A ghost eats the Pac-Man when it touches him.

Writing the Pac-Man Game in JavaFX - Part 3

By Haining Henry Zhang
May 25, 2009

We are now ready to create the ghosts in our game. The four ghosts, namely Blinky(red), Pinky(pink), Inky(cyan) and Clyde(orange), are trapped inside a cage when a game starts. After some time, they get out of the cage one by one and start roaming the maze. Their goal is to catch the Pac-Man. The Pac-Man dies if he is touched by one of the ghosts. If the Pac-Man swallows a magic dot, he has the power to eat ghosts for a while. During this time, the ghosts turn hollow and move more slowly.

Writing the Pac-Man Game in JavaFX - Part 2

By Haining Henry Zhang
May 14, 2009

In last article, we designed a data model and drew a maze with dots spread into the maze. Now we are ready to create the Pac-Man character. The Pac-Man character is controlled by the game player to move around the maze. While he is moving, he keeps gobbling dots along the path. To implement the Pac-Man character, we divide the coding into a few tasks so that we can create it bit by bit:

Writing the Pac-Man Game in JavaFX - Part 1

By Haining Henry Zhang
May 10, 2009

When I was young I was fascinated by arcade games. One of my favorites was the Pac-Man game.� Recently, when I was learning the JavaFX language, I decided to write the game in JavaFX.� Based on my experience in other programming languages, I assumed there would be some amount of work in building a game such as Pac-Man, giving me a good feel for RIA development in JavaFX.

Blue Sun? What an IBM acquisition of Sun means for software

By Kurt Cagle
March 24, 2009

However, Sun's software side of the acquisition ledger, especially by IBM, has been rather oddly overlooked, given that it will likely have major implications for software development and cloud computing for years. Sun's software holdings cover five primary areas - Java, Solaris, mySQL, Open Office, and Sun's recently acquired QLayer cloud infrastructure. Understanding how IBM could potentially ramp up (or destroy) each of these gives some interesting insight into the real value of IBM's potential software acquisitions.

Google Open Sources Google XML Pages

By Kurt Cagle
August 14, 2008

Given the mind-numbingly large number of pages that Google serves up every day, compiled efficiency is a key requirement for their web development team. However, as with many organizations, Google's team has also needed to split up their development efforts, so that web designers do not need to be programmers (and more importantly, do not need to endlessly spend their time validating and debugging low level code), and the core developers could spend time building components.

Neo4J: A Different Database (+ Expect More Bad Java News)

By Timothy M. O'Brien
July 12, 2008

Foocamp attendees, beware, we're covering you from afar. Peter Neubauer twittered about Neo4J this morning and it caught my eye. "Neo is a graph database. It is an embedded, disk-based, fully transactional Java persistence engine that stores data structured in graphs rather than in tables." Is this to be believed? Something interesting happening in Java?
