Our paper "Directed or Undirected: Investigating Fuzzing Strategies in a CI/CD Setup" is now up! www.carolemieux.com/cicd_tosem26.... Our goal was to investigate whether the overhead (in terms of compilation time) of directed fuzzers was worth it in a CI/CD setup (with time budget of 10 minutes).

CodaMOSA was built on Pynguin version 0.18 .... since then, Pynguin has been very much improved. Pynguin version 0.41.0 includes the LLMMOSA Algorithm, which integrates core parts of CodaMOSA into modern Pynguin! Many kudos to Pynguin contributors for this. github.com/se2p/pynguin...

A common follow-up, whenever we bring up parametric generators is "but can't those byte-level mutations result in a totally different generated input?" ....they do, but our experiments found those more destructive mutations generally lead to higher coverage. Our students fully explored this in:

Back from #ICSE25! I'm looking forward to reading "No Harness, No Problem: Oracle-guided Harnessing for Auto-generating C API Fuzzing Harnesses", by @gabriel-sherman.bsky.social and @snagycs.bsky.social.(users.cs.utah.edu/~snagy/paper...). Nice progress in fuzz driver generation!

🧠 Older models memorize more: Models like CodeGen, and CodeLlama show significantly higher leakage on Defects4J than newer models (e.g., Llama 3.1). They often reproduce patches verbatim, to the point that it’s weird (including comments!!) 🔥 3/
