All popular web browsers offer a “private browsing mode.” After a private session terminates, the browser is supposed to remove client-side evidence that the session occurred. Unfortunately, browsers still leak information through the file system, the browser cache, the DNS cache, and on-disk reflections of RAM such as the swap file. Veil is a new deployment framework that allows web developers...

We present Generalized Diffractometer Control (GDC), a diffractometer-control software package developed specifically for high-precision measurements of Bragg rods; we discuss its features and analyze its performance in data collection. GDC, implemented at several APS beamlines, controls a six-circle diffractometer in either Eulerian or kappa geometry, yet does not assume a mechanically ideal d...

Like many K-12 online learning programs, the Illinois Virtual High School (IVHS) began by utilizing vendor content to populate its online courses. In its fourth year, the IVHS began a concerted effort to design more of its own online course content internals. The aim of this study was to examine the nature of the support needed and application of tools used by IVHS course developers. The data c...

Mobile operating systems have evolved to provide increasing accessibility capabilities. However, mobile application developers are still restricted to deploy custom-made accessible applications or to extend limited and stereotyped accessibility services. In this paper, we present SWAT, an extensible framework that provides system-level content and event information to application developers. It...

This paper describes the design and evaluation of a new accessibility information resource, the Web Accessibility Information Resource (WebAIR), for assisting web developers in the creation of accessible websites and applications. Evaluations were conducted with 26 web developers in which they had opportunity to use both WebAIR and an existing accessibility information resource, the Web Content...

The names of variables and functions serve as implicit documentation are instrumental for program comprehension. But choosing good meaningful is hard. We perform a sequence experiments in which total 334 subjects required to choose given programming scenarios. first experiment shows that the probability two developers would select same name low: 47 instances our median was only 6.9%. At time, s...
