Creating a digital library requires converting the original scanned images into various formats. WolfpackSys is a software system that performs these large data conversion tasks in a distributed manner. The framework allows the best off-the-shelf conversion programs to be used in an automated system, and it runs the conversions in parallel on a large number of machines. It is currently used to perform image cropping, de-skewing, de-speckling, and OCR, as well as to create JPEG and Acrobat files from scanned images.
JChav is a way to see the change in performance of your Web application over time by running a benchmark test for each build you produce. It is an Ant task that, when used in conjunction with the JMeter ant task, produces historic views of the performance of your application. Charts are produced for individaul pages of the application along with summary data. If integrated with cruise-control or similar build tools, you will get an idea if the changes you are making to your Web application are improving or degrading performance.
