Rant: How to make whitebox PCs be less horrible.
This is totally off topic for Java, but I need to rant about computers for a second.

◀︎️ Older Page 8 of 12 Newer ▶︎I finally fixed my first Mustang bug!
So here it is, I finally fixed my first bug in Mustang. By this I do not mean that I have fixed only one bug during my year at Sun, but that I finally fixed the very first one I started on. The bug is JProgressBar (indeterm.) renders wrong on WindowsLookAndFeel, Windows2000 + XP, which basically means that indeterminate progress bars look horrible on XP.
Stuff to Play With: the EnumComboBoxModel
One of the great things about having a project like SwingLabs is that it gives me a place to put classes I've built that others might find useful. Today I'm going to describe my recent addition to SwingLabs, the EnumComboBoxModel, a cute little class that lets you stuff enums directly into your comboboxes with no extra work.
The Summer of 1998
Some time ago I wrote an article for Slashdot discussing Be, Apple, and the future of operating systems. The mention of Be should indicate just how far ago this was. The other day I decided to try to find the article both to find out if I was at all correct in my conclusions, and to see if my writing has improved at all. Well, I couldn't find the relevant article, as Slashdot's archives are not complete (and their search engine even less so) but as I was going backwards in time I ran across some articles that are quite interesting today. I suppose it's odd to think of something as recent as 6 years ago in an historical context, but in Internet years it must be centuries. So let's dive in:
Once more Matisse Rocks
I would just like to say that I'm more and more impressed with Matisse. It does it's absolute best to provide a realistic preview of running components at design time. Today I was building some component tests and was amazed to see that indeterminate progress bars are animated while in the designer! Have a look!
Props to the Trig Teacher
I'm working on a program that requires I convert degrees of longitude into miles. Since we are mapping radians on to the sphere (mostly) that is Earth, I needed to do some trigonometric calculations. Upon whipping out some paper and pencil and drawing the triangles I needed I realized had to remember which function to use. Is it Sine, Cosine, or Tangent? Hypotenuse over Adjacent? Adjacent over Opposite? All... blurring... together....
All hail the PropertyChangeListener
Often times when you are building an application you need to hook multiple components together in such a way that when one component changes others must do something. When you are building custom components there is often the temptation to build a custom set of listeners to go along with it. This seems like good component etiquette; after all this is how most of the javax.swing.* components are built. Still, that's a big pain to create new listener types that must be implemented, just for observing simple changes. Plus it tightly couples your classes which can make your code brittle when making changes later. There must be a better way. And there is!
My Mustang Beta Thoughts
By now you've probably all read
SwiXml builds better guis
Just a quick note to let you know that I've got a new article up about SwiXml. SwiXml is an open source library for building Swing GUI layout using XML instead of code (ie: the evilness that is GridBagLayout). In the article you'll learn what you need to get started using it and how it works. Check it out and let me know what you think. Also let me know what other articles you'd like to see. I'm looking for new ideas. Thanks Josh
Easily Use Custom Swing Components with Matisse
I know it's been quite a while since I've written anything. I've been busy with quite a few project and I'll have some cool stuff to share soon. In the meantime I thought I'd show you an interesting tidbit I discovered in Matisse and Netbeans.
Netbeans on Mac Tip
As some of you may know I'm a big Mac person. I split my time equally between my iBook (now heading back to the shop, alas) and my WinXP desktop. Being a dyed in the wool plain jane text editor type of programmer I've used jEdit for the past five years and have only recently started using an IDE like Netbeans. I've found Netbeans to a great productivity booster but on my iBook it seems to generate garbage at a mad pace. This is okay, it's just garbage, not a memory leak; but it's a pain when the editor locks up for five seconds to do garbage collection. Fortunately there is a solution.
I don't normally post about
I don't normally post about non Java related tech stuff, but I thought I would mention this really cool new filesystem called ">ZFS. It's part of Open Solaris but will most likely be ported to other OSes soon enough. Even though it's made by my employer I hadn't ever heard of it until news started hitting the web a couple of days ago (Sun is a big company, after all).
Why use Java for Web 2.0?
There's been a lot of talk lately about Web 2.0, and which technologies are going to take us there. We can debate the exact definition of Web 2.0, but I'd say a rough approximation would be an application which blurs the distinction between desktop apps and web apps. Many feel that the future is ultra-thin browser based client platforms like XUL or Ajax but I think that Java has a place, and will continue to grow in the future.

More of Tuesday
My First Full Day of JavaOne Japan
I woke up this morning painfully early, 4:00, which, as anyone who knows me can say, is the time that people should be going to bed, not waking up. Until recently I didn't even know there was a 4:00 in the morning. Oh well, such is the cost of jetlag. Considering I'm 14 (or 10) hours different I think I'm adjusting pretty well.
My LA-JUG Peabody Presentation
Last week I gave a presentation on Project Peabody for the Los Angeles Java Users Group, and I think it was well received. What's that? You've never heard of Project Peabody? That's okay. No one at the LA-JUG had heard of it either. We've only recently started using the name. Project Peabody is our community development project for new releases of Java; principally Mustang, aka: Java SE 6
Preparing for Tokyo
I'm spending today packing for my exciting trip to Japan this week. Yes, I managed to wrangle a trip to JavaOne Tokyo, where I will be speaking on Java 2D performance, Swing layout, and helping out with the Peabody booth.
Design of a distributed disaster relief system
Katrina is big. Too big. By Katrina I don't mean the storm, but the overall situation. I feel like I did almost four years ago, unable to help or even understand much but realizing that our disaster services simply aren't up to the task. Sitting in California with sunny weather I wait, watch, and wonder what I can do.
Swing Hacks Bonus Article
Time stands still for no man. Technology even less so. The world moves on and we have to adapt.
Get Swing Hacks for Five bucks
I just got an email from my co-author and looked up the Fry's ads for the San Jose Mercury news. If you live in the Bay Area (or San Jose, at least) then you can get a copy of Swing Hacks for 20$ minus a 15 dollar rebate, for a final cost of 5 bucks. Supposedly it's even cheaper in Atlanta. I don't know what stores this applies to so be sure to check out the ads for the local Fry's in your area. So if you've been wanting to get the book it's on sale. Also be on the look out for a new article feature more Swing Hacks material that didn't make it into the book.
