A software bug is a design defect in computer software. A computer program with many or serious bugs may be described as buggy . The effects of a software bug range from minor (such as a misspelled word in the user interface ) to severe (such as frequent crashing ).
The term bug applies exclusively to a system that is (human) designed; not to a natural system; and that the issue is within the influence of human control. For example, humans have faults but not bugs, and a server crash due to natural disaster is not a bug. In addition to or instead of defect, some use: error, flaw or fault.
An issue tracking system often also contains a knowledge base containing information on each customer, resolutions to common problems, and other such data. An issue tracking system is similar to a " bugtracker ", and often, a software company will sell both, and some bugtrackers are capable of being used as an issue tracking system, and vice versa.
[1] Issues Papers were the vehicle the AICPA's Accounting Standards Executive Committee (AcSEC) used to present emerging practice problems to the FASB and accounting practitioners. Issues Papers generally followed a standard format: (1) background, (2) analysis of current practice, (3) review of the literature, (4) statement of issues needing ...
The DAO bug. On June 17, 2016, the DAO was subjected to an attack exploiting a combination of vulnerabilities, including the one concerning recursive calls, that resulted in the transfer of 3.6 million Ether – around a third of the 11.5 million Ether that had been committed to The DAO – valued at the time at around $50M.
A major component of a bug tracking system is a database that records facts about known bugs. Facts may include the time a bug was reported, its severity, the erroneous program behavior, and details on how to reproduce the bug; as well as the identity of the person who reported it and any programmers who may be working on fixing it.
The first software configuration management was a manual operation. With the advances in language and complexity, software engineering, involving configuration management and other methods, became a major concern due to issues like schedule, budget, and quality. Practical lessons, over the years, had led to the definition, and establishment, of ...
These numerous code-level issues eventually count for only 10 percent of the defects in production. Bad software engineering practices at the architecture levels account for only 8 percent of total defects, but consume over half the effort spent on fixing problems, and lead to 90 percent of the serious reliability, security, and efficiency ...
