Teaching rigorous distributed systems with efficient model checking

Teaching rigorous distributed systems with efficient model checking Michael et al., EuroSys'19 On the surface you might think today’s paper selection an odd pick. It describes the labs environment, DSLabs, developed at the University of Washington to accompany a course in distributed systems. During the ten week course, students implement four different assignments: an exactly-once ... Continue Reading

How not to structure your database-backed web applications: a study of performance bugs in the wild

How not to structure your database-backed web applications: a study of performance bugs in the wild Yang et al., ICSE'18 This is a fascinating study of the problems people get into when using ORMs to handle persistence concerns in their web applications. The authors study real-world applications and distil a catalogue of common performance anti-patterns. ... Continue Reading

Deep code search

Deep code search Gu et al., ICSE'18 The problem with searching for code is that the query, e.g. "read an object from xml," doesn’t look very much like the source code snippets that are the intended results, e.g.: * That’s why we have Stack Overflow! Stack Overflow can help with ‘how to’ style queries, but ... Continue Reading

Automated localization for unreproducible builds

Automated localization for unreproducible builds Ren et al., ICSE'18 Reproducible builds are an important component of integrity in the software supply chain. Attacks against package repositories and build environments may compromise binaries and produce packages with backdoors (see this report for a recent prominent example of compromised packages on DockerHub). If the same source files ... Continue Reading

Generalized data structure synthesis

Generalized data structure synthesis Loncaric et al., ICSE'18 Many systems have a few key data structures at their heart. Finding correct and efficient implementations for these data structures is not always easy. Today’s paper introduces Cozy (https://cozy.uwplse.org), which can handle this task for you given a high-level specification of the state, queries, and update operations ... Continue Reading

ConflictJS: finding and understanding conflicts between JavaScript libraries

ConflictJS: finding and understanding conflicts between JavaScript libraries Patra et al., ICSE'18 The JavaScript ecosystem is fertile ground for dependency hell. With so many libraries being made available and the potential for global namespace clashes, it’s easy for libraries to break each other. Sometimes in an obvious to spot way (that’s a good day!), and ... Continue Reading
