Software bugs affect system reliability. When a bug is exposed in the field, developers need to fix them. Unfortunately, the bug-fixing process can also introduce errors, which leads to buggy patches that further aggravate the damage to end users and erode software vendors’ reputation. This paper presents a comprehensive characteristic study on incorrect bug-fixes from large operating system co...

In this paper, we propose a software tool that can be used to speed up the software development lifecycle by automating the process of assigning new bugs to developers. Open bug repositories are now very common, and they are provided to the software users as a means to report any bugs they find while using the software. Many of the bugs reported complain about exceptions that are thrown by the ...

Managers of open source projects need to understand time to resolve bugs, which are reported into a bug tracking system on a daily basis, to make a release plan. Hewett et al. proposed an empirical approach to predicting time required to repair bugs. However, the predictive model did not distinguish between time to modify a firstly-reported bug and time to re-modify a bug. In this paper, toward...

Until recently, bed bugs have been considered uncommon in the industrialized world. This study determined the extent of reemerging bed bug infestations in homeless shelters and other locations in Toronto, Canada. Toronto Public Health documented complaints of bed bug infestations from 46 locations in 2003, most commonly apartments (63%), shelters (15%), and rooming houses (11%). Pest control op...

Statistical debugging is a powerful technique for identifying bugs that do not violate programming rules or program invariants. Previously known statistical debugging techniques are offline bug isolation (or localization) techniques. In these techniques, the program dumps data during its execution, which is used by offline statistical analysis to discover differences in passing and failing exec...

BACKGROUND Stink bugs (Hemiptera: Pentatomidae) comprise a critically important insect pest complex affecting 12 major crops worldwide including cotton. In the US, stink bug damage to developing cotton bolls causes boll abscission, lint staining, reduced fiber quality, and reduced yields with estimated losses ranging from 10 to 60 million dollars annually. Unfortunately, scouting for stink bug ...

The bed bug, Cimex lectularius L., like other bed bug species, is difÞcult to visually locate because it is cryptic. Detector dogs are useful for locating bed bugs because they use olfaction rather than vision. Dogs were trained to detect the bed bug (as few as one adult male or female) and viable bed bug eggs (Þve, collected5Ð6dafter feeding)byusingamodiÞed foodandverbal reward system.Their ef...

Context: Bug fixing is an integral part of software development and maintenance. A large number of bugs often indicate poor software quality, since buggy behavior not only causes failures that may be costly but also has a detrimental effect on the user’s overall experience with the software product. The impact of long lived bugs can be even more critical since experiencing the same bug version ...

Sumner, William N. Ph.D., Purdue University, December 2013. Automated Failure Explanation through Execution Comparison. Major Professor: Xiangyu Zhang. When fixing a bug in software, developers must build an understanding or explanation of the bug and how the bug flows through a program. The effort that developers must put into building this explanation is costly and laborious. Thus, developers...

Empirical studies indicate that automating the bug assignment process (also known as bug triaging) has the potential to significantly reduce software evolution effort and costs. Prior work has used machine learning techniques to automate bug triaging but has employed a narrow band of tools which can be ineffective in large, long-lived software projects. To redress this situation, in this paper ...
