The Sordid Tale of XML Catalogs

I am finishing the code samples for my book “Scala for the Impatient”. (Yes, for those of you who are impatiently awaiting it—the end is near. Very near.)

In the XML...

Operator Overloading Considered Challenging

Java has no operator overloading. I always thought that was a shame. For example, BigDecimal would be a lot more popular if you could write a * b instead of a....

A first look at Dart

Google released details about the Dart language today, and I am surprised howmuch more it is like Java than like JavaScript. I had expected either a prototype-based language, a streamlined...

JavaOne 2011 Day 4

Another day, another keynote. A fellow from IBM talked about cloud stuff. I sat through a lot of nebulous cloud talks, but this guy was good.

JavaOne 2011 Day 3

The Script Bowl is another JavaOne tradition. The candidates...

JavaOne 2011 Day 2

Here I am, on my second day of Java One. I live in the residential part of San Francisco and get to the conference on a battered “express” bus that stops at every block, starting from...

JavaOne 2011 Day 1

Today, JavaOne started officially. With the traditional keynote. Except, traditionally, the keynote is in a huge room that has space for everyone. Today, people were shunted into overflow rooms...

JavaOne 2011 Day 0

Once again, I got a blogging pass to JavaOne—my fifth year as the intrepid reporter at JavaOne, and my 15th JavaOne attendance. Sadly, that wasn't enough to get me the coveted Alumni badge...

Scala for the Impatient—Free Chapters at typesafe.com

My hard-hitting, tell-it-as-it-is Scala book draft is coming along. No animals or fruit have been pressed into service for contrived examples. Free chapters are at typesafe.com. ♦

Whatever Floats Your Boat

Inner Classes in Scala and Java

Java 7 Unsafe at Any Speed?

In Praise of Language Specs

I give an example of why having a language spec builds confidence in a situation that would induce fear and trembling in a seat-of-the-pants programming language. I boldly generalize to posit...

There Will Be Monads

I finished my "modern programming languages" course at the Ho Chi Minh City University of Technology. We covered metaprogramming (with Ruby and Rails), continuations (with Racket and Scala...

Easy Red-Black Trees

A red-black tree is a binary search tree with the following additional properties:

A Dozen Concurrency Pitfalls
I needed some filler material for my lectures on concurrency. I googled around for Java concurrency pitfalls and came up with a nice mixture of golden oldies and new ones (at least new to me). I...
Parallel Arrays in Scala

Having a Racket with Pictures and Continuations
In this blog, I describe how the Racket language provides fun graphics and a nifty web framework. The  former is great for beginning students, and the latter is helpful for grasping the mind-bending...
A Blog Uploading Tool for java.net

In this blog, I address my grief with blog uploading, following Paul Graham's advice about choosing technology. ♦ 

Ruby, Scala, and Complexity

In this blog, I ponder why Ruby and Scala are easy to learn and complex to master, and how their cultures differ. ♦

Scala for the Impatient

In 1995, I got a call from Gary Cornell who told me that we were going to write a Java book. That surprised me—I didn't know any Java, and I was pretty sure that Gary didn't know it either....

A Report from the Sewer Hole: Cygwin, JLine, rxvt, and the Scala REPL

I have students running Windows, Linux, and Mac OS X, and I like to encourage students to choose whatever platform makes them most productive. But I also like to be able to give out one set of...

A Condensed Monospaced Font

When the time comes for my graduate students to write their project reports, I give them a long checklist of do's and don'ts. One of the more vexing issues is the code font. I am astonished how...

The Mystery of the PolicyNodeImpl Class

When Oracle, in its Android lawsuit, accused Google of copyright violation, I didn't think this was going to stick. I was pretty surprised when the PolicyNodeImpl comparison made its...

A Geometry Problem in Scala

I ran into this blog about making a pretty drawing in C# and F#.

Java One From Far Away

The Next Big JVM Language

Stephen Colebourne has a very interesting article on the Next Big JVM Language (NBJL). The comments are good too...

PrimeFaces works great with JSF 2.0/NetBeans 6.9

In 2002, JSF was introduced at Java One as “Swing for the Web”. The vision was that you would compose professionally designed components into web pages, add a bit of Java glue code,...
