Code comments are the primary means to document implementation and facilitate program comprehension. Thus, their quality should be a primary concern to improve program maintenance. While much effort has been dedicated to detecting bad smells, such as clones in code, little work has focused on comments. In this paper we present our solution to detect clones in comments that developers should...

Software testing depends on effective oracles. Implicit oracles, such as checks for program crashes, are widely applicable but narrow in scope. Oracles based on formal specifications can reveal applicationspecific failures, but specifications are expensive to obtain and maintain. Metamorphic oracles are somewhere in-between. They test equivalence among different procedures to detect semantic...

Context: A Machine Learning based System (MLS) is a software system including one or more components that learn how to perform a task from a given data set. The increasing adoption of MLSs in safety critical domains such as autonomous driving, healthcare, and finance has fostered much attention towards the quality assurance of such systems. Despite the advances in software testing, MLSs bring...

In 1996, the newly founded Academy of Architecture of Mendrisio invited Peter Zumthor to be the professor in charge of one of the school’s first three design studios. What took form from that was a singular educational experience, conducted by Zumthor as a didactic project spanning a three-year period - the academic years of 1996-97, 1997-98 and 1998-99 - and comprehending a sequence of 19...

Mining Software Repositories (MSR) has become a complete and mature research field, also due to the increasing number of open source projects publicly available. Repository hosting services such as GitHub provide unprecedented access to millions of events generated during development activities (e.g., code commits, pull requests), that can be mined and analyzed to extract new pieces of...

The purpose of this document is to define the state of the art regarding information technology infrastructure automation. Nowadays, companies need a way to automate their infrastructure to reduce their expenses and avoid wasting time. System administrators could then work with more efficiency and focus on solving challenges in the company that actually require human intervention. An overview...

Understanding the performance of software is complicated. For several performance metrics, in addition to the algorithmic complexity, one must also consider the dynamics of running a program within different combinations of hardware and software environments. Such dynamical aspects are not visible from the code alone, and any kind of static analysis falls short. For example, in reality, the...
