On Friday, during lunch break, I recorded new video tutorials (this time with sound) for using weka-virtualenv on Linux, how to use the tool in general and how to associate ARFF files with it as well. Yesterday, I did the same for Windows, but came across a weird bug when executing J48: no output was produced at all. Looks like Windows flushes stdout/stderr differently compared to Linux, as it seems to occur after the process has already finished. Hence I pushed out a bugfix release for the processoutput4j library, which weka-virtualenv uses. The current release is 0.0.15 now.
You can find the video tutorials in the following Youtube playlist:
