First of all, what is “software bug”? Everyone understands that it isn’t an insect ( well, not anymore, anyway :-) ). According to Wikipedia: software bug is an error, flaw, failure, or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways.” Some bugs can be detected easily during development. But some bugs might be found late in the development process. There have been many attempts to classify the bugs. Most of these represent the general classification which is valid in the cycle of software development and evolution. The classification scheme given in Orthogonal Defect Classification defines eight categories of defects as assignment, checking, algorithm, interface, timing/serial, function documentation, and build/pack/merge. Most everything in such classification understandable, useful and boring. But, sometimes, going through a code, you may face a dark horse from the bug's world. There are ...

In honor of Women's Day, we would like to pay tribute to the women in Information Technology. Modern IT world viewed only as "a boy's thing". But this is not totally true. A lot of computing pioneers — the people who programmed the first digital computers — were women. Now, less than 25% of the IT workforce are women, but in the software testing sector the percentage filled by women is now approaching 50%. Women’s typical cognitive differences make them invaluable to IT teams. Let's pay attention to the history. One might believe that women did not play an important role in the beginnings of computer science, but in reality they have made significant contributions in many areas, starting from the early days. In any discussion of the pioneers in computing, the names of two visionaries immediately come to mind:

• Augusta Ada Byron Lovelace (1815 – 1852). She is ...
