Though refactoring tools have been available for more than a decade, research has shown
that programmers underutilize such tools. However, little is known about why programmers …

Writing reliable test suites for large object-oriented systems is complex and time consuming.
One common cause of unreliable test suites are test dependencies that can cause tests to …

Many recent parallelization tools lower the barrier for parallelizing a program, but overlook
one of the first questions that a programmer needs to answer: which parts of the program …

Running compute-intensive or blocking I/O operations in the UI event thread of smartphone
apps can severely degrade responsiveness. Despite the fact that Android supports writing …

To avoid unresponsiveness, a core part of mobile development is asynchronous
programming. Android providesseveral async constructs that developers can use. However …

Modern IDEs for object-oriented languages like Java provide support for a basic set of
simple automated refactorings whose behaviour is easy to describe intuitively. It is, however …

In the multicore era, a major programming task will be to make programs more parallel. This
is tedious because it requires changing many lines of code; it's also error-prone and …

Asynchronous programming is in demand today, because responsiveness is increasingly
important on all modern devices. Yet, we know little about how developers use …

The JavaScript ecosystem provides equivalent synchronous and asynchronous Application
Programming Interfaces (APIs) for many commonly used I/O operations. Synchronous APIs …

In the multicore era, sequential programs need to be refactored for parallelism. The next
version of Java provides ParallelArray, an array datastructure that supports parallel …
