Source Code Release

I finished my Open Source software project CroftSoft Infant. My collaborator was able to use the software successfully to collect research data.

She wanted a new software feature added for a new type of experiment. She recruited a programmer to add the feature but he had some problems checking out the latest version of my code from the source code repository using CVS. I then realized it had been four years since I exported my code to a zip file for easy download so I did that tonight. You can get it by downloading the latest file release of the CroftSoft Code Library.

Development PC Setup

Ever since I wrote my first computer program back in 1980, I have had to recreate and customize my software development environment to my liking on new computers at home, work, and school at least once a year. Tonight I uploaded my Development PC Setup checklist to speed me through this process of configuring a new Windows computer and installing my preferred free and Open Source software development tools. Please save a link to this webpage in your online bookmarks as I plan to update it each time I use it.

Retirement Calculator

I updated and installed a Retirement Calculator servlet that I wrote back in 1999. The source code is available.

Switched to LGPLv3

The Free Software Foundation (FSF) recently published version 3 of the GNU Lesser General Public License (LGPLv3). This update to the popular non-viral Open Source license covers patent usage, implied but not explicit in previous versions. It also blocks "tivoization" which is described in the FSF release announcement.

Today I switched the Open Source license for the CroftSoft Code Library over to the LGPLv3 since I think preventing tivoization is a good idea. I can foresee that in the near future it will become more common to have code running in devices within or permanently attached to our bodies, especially as neuroprosthetics technology advances. Having the option to modify this code seems like it should be a basic right.

CroftSoft Skipper

Today I published CroftSoft Skipper. Like the previously released CroftSoft Slideshow, CroftSoft Skipper will display a slideshow of the photos on your computer. The feature that makes CroftSoft Skipper smart is "skip weighting": when you skip a photo you do not like, that photo is less likely to be randomly selected for display in the future.

Enumerated Accessors

As an update to the "Persistent Data" chapter in my book Advanced Java Game Programming, I have written a new tutorial, Enumerated Accessors. Data management and persistence are simplified by using new features that have been added to the Java programming language such as enumerated types and JAXB.

Wireshark

I recently used the Open Source packet sniffer Wireshark to decode a custom client-server protocol for relaying telemetry data. Without the use of the packet sniffer, I might have been stuck with no way to progress. I have added Wireshark to my list of Links to useful free and Open Source software development tools.

Interface Seq

I wrote a tutorial for Inteface Seq, a Java interface I created to provide read-only access to a sequence such as an object array or a List.

World Community Grid

My new development desktop has two quad-core processors. I was feeling a little inefficient with all of this computing power sitting around mostly unused so I decided to revisit distributed computing projects. In particular, I was interested in contributing my idle CPU cycles to biomedical research. I settled on the World Community Grid with the Open Source BOINC client.
