Understanding what affects software developer productivity can help organizations choose wise investments in their technical and social environment. But the research literature either focuses on what correlates with developer productivity in realistic settings or focuses on what causes developer productivity in highly constrained settings. In this paper, we bridge the gap by studying software...

Modern software development requires developers to find and effectively utilize new APIs and their documentation, but documentation has many well-known issues. Despite this, developers eventually overcome these issues but have no way of sharing what they learned. We investigate sharing this documentation-specific information through annotations, which have advantages over developer forums as...

In this paper, we show that the unsoundness discovered by Amin and Tate (2016) in Java’s wildcards is avoidable, even in the absence of a nullness-aware type system. The key insight of this paper is that soundness in type systems that implicitly introduce existential types through subtyping hinges on still making sure there are suitable witness types when introducing existentially quantified...

This chapter explores the possibility of building a unified assessment methodology for software reliability and security. The fault injection methodology originally designed for reliability assessment is extended to quantify and characterize the security defense aspect of native applications. Native application refers to system software written in C/C++ programming language. Specifically,...
