top 10 bugs

We all know that when we write multithreaded programming, we should remember a lot of details, such as locks, the use of thread-safe libraries, and so on. Here is a list of less obvious bugs , specific to multithreaded programs. Many of them are not mentioned in the beginner's documentation or tutorials, but I think everyone who uses threads will eventually get shot. Using the thead safe system function Not all system functions, or libra

/* Expectation of DP inverse recursive solution: a software has s sub-systems, which produce n kinds of bugs. Someone finds a bug one day. This bug belongs to a sub-system, the probability that a bug belongs to a subsystem is 1/s. The probability of a bug belongs to a certain classification is that 1/N queries discover n kinds of bugs, and each subsystem is expected to discover the number of days of the bug

This problem often occurs recently. When a function is clearly completed, a bug occurs during the overall test, and a process is clearly a test, there are still many blind spots from products to customers that have not been tested. Maybe there will be fewer companies in the testing team, which is unknown. In my opinion, small companies still cannot afford the consumption of the testing team. If there is no testing team, what should I do if I only test functions developed by developers ??, Maybe

Luatinker bugs and defectsLuatinker is a good set of C + + code and LUA code binding library, the author is Korean Kwon-il Lee, the author should be referring to the luabind, in order to simplify and avoid too heavy to achieve.

There is no doubt that programmers are good at thinking about problems. A program is written through the basic stages of thinking, design, writing, debugging, testing, and running. But most programmers have a problem that they are reluctant to test their own code. After the debugging is completed, they think that the work is over. testing is the work of testers. Theoretically, if there is a problem with the code, the tester and the end user will certainly be able to find these

What is Haslayout？Haslayout is an attribute unique to ie. Many of the CSS bugs under IE are closely related to them. In IE, an element either calculates the size and organization of its own content, or relies on the parent element to calculate the size and organization of the content. When the value of an element's Haslayout property is true, it is responsible for sizing and positioning itself and possible descendant elements.While this means that the

We often see this phenomenon when we browse the Web page: It is normal for a webpage to open in IE6 browser, but opening in IE8 may be completely distorted. Or there is the possibility of a completely opposite phenomenon. This makes it painful for web programmers and designers to behave strangely for their CSS in various versions of IE, sometimes by designing separate definitions specifically for IE6 or IE8. IE is therefore recognized as a Web programmer's poison, although the Microsoft Official
