SD Times Open-Source Project of the Week: Swap Detector

Swap Detector is an open-source checker that detects API usage errors. The project was released this week by GrammaTech, and originally created by The Department of Homeland Security, Science and Technology Directorate, and Static Tool Analysis Modernization Project.

“Traditional static-analysis techniques do not take advantage of the vast wealth of information on what represents error-free coding practices available in the open-source domain,” said Alexey Loginov, the vice president of research at GrammaTech. “With Swap Detector we applied Big Data analysis techniques, what we call Big Code analysis, to the Fedora RPM open-source repository to baseline correct API usage. This allowed us to develop error-detection capabilities that far exceed the scalability and accuracy of conventional approaches to program analysis.”

Swap Detector enables developers and DevOps teams to identify errors due to swapped function arguments, which can also be present in deployed code.

It consumes input information about a call site and function declaration information pertaining to that call site. If it detects a potential swapped-argument error at that call site, it outputs an appropriate warning message and a score for the warning.

Swap Detector also integrates with a variety of static analysis tools such as Clang Static Analyzer, Clang-Tidy, and PyLint, and is especially beneficial for languages that are interpreted and not compiled, according to GrammaTech.

The software uses “Big Code” techniques and applies statistical information about usages of “known good” API-usage patterns collected from a large corpus of code, and flags usages that are statistically anomalous as potential errors.

Additional details are available here.

Difference between Web Designer and Web Developer Neeraj Mishra The Crazy Programmer

Have you ever wondered about the distinctions between web developers’ and web designers’ duties and obligations? You’re not alone! Many people have trouble distinguishing between these two. Although they collaborate to publish new websites on the internet, web developers and web designers play very different roles. To put these job possibilities into perspective, consider the construction of a house. To create a vision for the house, including the visual components, the space planning and layout, the materials, and the overall appearance and sense of the space, you need an architect. That said, to translate an idea into a building, you need construction professionals to take those architectural drawings and put them into practice. Image Source In a similar vein, web development and design work together to create websites. Let’s examine the major responsibilities and distinctions between web developers and web designers. Let’s get going, shall we? What Does a Web Designer Do?...
