A collection of official Android documentation that I wrote while employed at Google, with editorial tweaks from the amazing tech writers I worked with! Includes build and project structure overviews and details on dependency resolution and maintenance. Read on for the links! Good stuff!
I've been teaching an Android class for Johns Hopkins University since 2012. It's gone through many iterations over time, from development environments to languages to UI frameworks. Most days I wish I just taught math. Math doesn't change like this every year. Read on for the current and legacy content links.
I taught a single-term Domain-Specific Languages class for Johns Hopkins University in 2018. Read on for the video playlist link!
I've been teaching a live Kotlin class for Johns Hopkins University since 2020. Read on for the latest video playlist link!
Android Studio makes it crazy easy to locate deadlocks! I'll explain how in this video.
Let's learn Kotlin from a Java point of view. We'll start by looking at some basics of Variables, Values, Classes, Properties and Constructors.
A Tech Talk I gave for Johns Hopkins University June 28, 2017. What is a Domain-Specific Language? How can we use one for code-generation?

A Java Users Group talk from September 2014 I presented on new features in Java 8: Lambdas and Streams.
A Java Users Group talk from July 2013 I presented on new features in JCode Generation with xText and xTend. We'll use xText to create a custom language by specifying a grammar, read the content into a model, and generate code using xTend!
A Java Users Group talk I presented on enumerations in Java. I cover: The old "type-safe enumeration pattern" Using enums for values Adding data and methods to enums Using enums for the Gang-of-Four State Pattern Using enums to emulate function pointers in Java EnumSet and EnumMap
I presented a talk on the Template Method and Strategy Patterns to the Columbia, Maryland Java Users Group on 10/13/2011.
I presented a talk on Dynamic Proxies to the Columbia, Maryland Java Users Group on 12/02/2010.
A Java Users Group talk from May 2010 I presented on Eclipse tips and tricks.
I presented a talk on Java Annotations to the Columbia, Maryland Java Users Group on 1/19/2010. This is a very deep dive into Annotation Concepts Creating annotation processors Using annotations at compile time and runtime Generating code from annotations
A video tutorial on ANTLR 3.x
ANTXR: Easy XML Parsing, based on the ANTLR parser generator
There should never exist any language feature such that adding a new type to a referenced package can break your existing code. Import-on-demand (aka "start imports") is one such feature... And it's evil...
I'm really tired of hearing folks incorrectly state "primitives are passed by value, objects are passed by reference". So I'm gonna rant, and you're gonna listen...
Maintainable applications can be quite tricky to develop. One of the keys to creating such a beast, is to properly layer your application.
A tutorial on ANTLR 2.x
Converting from LALR to LL can be challenging... Hopefully this article will make it a weeeeee bit simpler...
Property editors are a way to make your bean more user-friendly. Bean builder tools can determine quite a lot about your bean just by looking at it and its corresponding BeanInfo class, but they usually have only very simple methods of editing the properties in the bean.
Automatic Expansion of Java Import Statements
Some talks I gave at JavaOne in 2000, 2001, and 2002.
Simple Swing Border Editing in GUI Builders
The basics of the JavaBean Component Model
Accessors are a key ingredient to proper encapsulation. The can restrict access to only read/write data, inform other objects of changes to data, and perform validation on new values being set. Consistent accessor usage makes class modification easy and transparent.
Java provides three types of comments; when should we use which?
A VisualAge for Java plugin to create interfaces from classes
A Layout Manager for Split Windows
JavaBeans for BoxLayout Visualization
Visual Debugging for ANTLR 2.x
Way Cool (And Antiquated) Tabbed Panel Component
Let's get familiar with Java Layout Managers!
