Fun with Time Zones in Java 8
[Note: Revised based on suggestions in the comments.] They say that one way to identify a software developer is to whisper the word “timezone” in their ear and see if they shudder. That’s certainly true for me, though my reaction is based more on travel and trying to arrange conference calls across time zones than…

Groovy Weather: A New Groovy Example at Java.net
One of the main goals of Making Java Groovy is to show Java developers how much Groovy can make their lives easier. To that end, I just published a blog post (through Manning’s account) over a Java.net entitled, Groovy Weather: POGOs, Gson, and Open Weather. The blog post comes with a coupon code for 45%…

Making Java Groovy at JavaOne 2013
Monday morning I gave my “Making Java Groovy” presentation at JavaOne in San Francisco. This is my first trip to JavaOne, and the sheer size of it is rather overwhelming. Of course, it’s also obvious at almost every turn that JavaOne is the weak sister of Oracle Open World, but hey, it could have been…

Making Java Groovy: Operator Overloading
This is partly a spoiler for my “Making Java Groovy” talk that I normally do at NFJS events and plan to use in my similar talk at JavaOne, but to celebrate the book going to the printer I thought I’d try to contribute something technical here. I’ve always felt that one of the keys to…

NetBeans 6.1 is a lot better than I thought
This week I’m in New Haven, CT, teaching a class that combines UML and Java Web Services (an odd combination to be sure). The client wanted to use NetBeans as their primary IDE, and I always try to accommodate that if I can. My last exposure to NetBeans was back in version 5.5, I think,…

Nothing makes you want Groovy more than XML
I’m in Delaware this week teaching a course in Java Web Services using RAD7. The materials include a chapter on basic XML parsing using Java. An exercise at the end of the chapter presented the students with a trivial XML file, similar to: <library> <book isbn=”1932394842″> <title>Groovy in Action</title> <author>Dierk Koenig</author> </book> <book isbn=”1590597583″> <title>Definitive…

Library quirk in the new Eclipse, and random framework musings
I’ve been working with Struts 2 recently, and like most frameworks it relies on a set of jar files. I like to work with Eclipse as my primary IDE. In that framework, my normal mode of operating is to create a User Library containing the jar files I need and then add it to my…

Go to see Grails, learn about Hibernate
Today I finally got to see the two Grails presentations by Jason Rudolph at No Fluff, Just Stuff. It’s not really an exaggeration to say I decided to attend the conference largely because I knew he’d be there. I like the NFJS conferences, but since I’m a one-person company, the “budget” for the conference comes…

Some No Fluff, Just Stuff observations
I’ve finished two of the three days of the current No Fluff, Just Stuff conference, officially known as the New England Software Symposium. I’ve got a fair amount to process now, but here are some random observations, in no particular order: If the NFJS people have any say in it, Groovy and Grails are definitely…

Where have I been (my Google Maps Mashup)?
The user interface leaves a lot to be desired, but my Google Maps mashup went live today. If you want to see where I’ve taught courses over the past three years, you can go here and see. All of the data is stored in a very simple database consisting of three tables: Courses, Locations, and…
