will a recording of the talk be available elsewhere?
I cannot use zoom but I'm interested in this talk.

> Reproducibility is the ability of recreating identical binaries under 
> pre-defined build environments. Due to the need of quality assurance and 
> the benefit of better detecting attacks against build environments, the 
> practice of reproducible builds has gained popularity in many 
> open-source software repositories such as Debian and Bitcoin. However, 
> identifying the unreproducible issues remains a labour intensive and 
> time-consuming challenge. In this talk, we introduce a technique called 
> RepLoc of localizing the problematic files for unreproducible builds. 
> RepLoc features a query augmentation component that utilizes the 
> information extracted from the build logs, and a heuristic rule-based 
> filtering component that narrows the search scope. By integrating the 
> two components with a weighted file ranking module, RepLoc is able to 
> automatically produce a ranked list of files that are helpful in 
> locating the problematic files for the unreproducible builds. We have 
> implemented a prototype and conducted extensive experiments over 671 
> real-world unreproducible Debian packages in four different categories. 
> After introducing the localization of unreproducible builds, the talk 
> presents several of our efforts that address the reproduction of 
> software behaviors.
