I finally wrote a small tool I've wanted for a long time: A parallel testcase minimizer. It's called halfempty, and I'm already finding it useful as part of my fuzzing workflow. /cc @lcamtuf github.com/googleprojectz… pic.twitter.com/qleqrRbTDy

Other than parallelization is your bisectional method significantly different than Delta Debugging?

No, parallelization is the main new contribution. I do have some ideas for other strategies though, but I guess we'll see how well they work when I finish writing them 🙂

how's it compare with parallel C-Reduce, algorithm-wise? blog.regehr.org/archives/749

Thanks for the link, sounds like a very different approach - interesting to think about though.

This maybe a silly question but have you ever written or talk about you RE workflow? I find it interesting to see other people workflow because I helps me find gaps on my workflow and I have always wander about yours.

I heard Tavis' vulnerbility finding workflow consists of IDA printouts and a dart.

A long time ago, I wrote a quick bash script to parallelize afl-tmin to X cores. Works mostly well but could be more efficient.

you might be interested to hear about c-reduce, if you haven't yet: embed.cs.utah.edu/creduce/
it has been used primarily to reduce compiler bug test cases
