Context menu in OS X to resize images

I used this link to set up an entry in the context menu for automagically resizing images in OS X.

I changed things around a little, since there is already a way to resize images I did not need to write a shell script using ImageMagick.

New direction

I am taking this blog in a new direction. I did not want to just create a new blog because some of the information here, while not relevant to photography is important to me.

So from now on this will be used to post photography information and what I learn with my new hobby.

Not much going on

Just wanted to make sure all of you know that I am still alive and kicking. Not much going on in my computing life. I did leave my position at ITT April 14 and started a new job at ???. Not sure I can tell you much other than the number of question marks equal the number of letters in the name of the place..I'll let you do the math.

I did pick up an iMac a few months ago and really like it. I have a .mac account and my username is 'iammarkwebb' if you would like to check it out.

Photographer site from hockey tournament

Here is a link
to the site of the photographer that took tons of pictures at Brandon's hockey tournament this weekend at Oswego.

Safe HashMap

This is a really cool class that allows for lazy initialization and removed the possibility of having null values in the HashMap. Another nice feature is that it is generics-capable.

Now if this class was thread safe, we would have a complete solution....

CopyOnWriteMap

I finally got around to writing an implementation of java.util.Map, which provides a fast, concurrent way to access a Map. Write operations are more expensive, but you would only want to use this class if reading is your primary objective. I had found a few other implementations of a copy-on-write Map, but I did not think they were quite right. With some help from the MINA team, I have the class in the trunk of MINA and all is well.

Andy McKee

This guy is simply amazing. If you appreciate music even a little, you will love what Andy Mckee
can do with a guitar. He has many of his songs on youtube, and you can also get his music on iTunes.

Abstract Dialog Class

Here is the code from a class that I have used for years. This class extends JDialog in a way that adding components to it is very painless, since it uses GridBagLayout. I hope to soon comment it better and add an example, but for now you will have to look at the code to see what is going on.

package org.markwebb.gui;

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import java.awt.Insets;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.BorderFactory;
import javax.swing.JButton;
import javax.swing.JComponent;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.border.TitledBorder;

/**
 * This is an abstract class which takes many of the pains out of
 * GridBagLayout.  The Dialog is set to modal.
