In the daily development process will inevitably leave some bugs due to negligence, these bugs are buried in the program of time bombs, if not timely eradication will lead to program instability, abnormal or flashback phenomenon, resulting in a decline in user experience. So how do you find out the time bombs buried in the program?The most headache for programmers is to find a bug, especially to find their

under the Epiphany, Galleon,mac under the Camino and so on. It is customary to call them the Mozilla family (Mozilla Family). Because this chapter involves less content (they are basically perfect, no bugs can make me increase the number of words), I prefer to talk about history, MO:). Firefox in the name also called Firebird, Phoenix has attracted the attention of CSS designers. The Gecko engine is very close to the rules of the CSS3, and there are

A lot of the advice about programming style is to create high-quality, maintainable code, which is reasonable, because the easiest time to fix bugs is before a bug is created (a small amount of precautions ...). ）。 Unfortunately, only prevention is often not enough, although there are some ingenious tools to help you create good code, but few tools can help you analyze, maintain, or improve the quality of your existing code. It is difficult to write

when developers submit their work, they can reduce the time that other developers use to detect bugs, and it is often difficult to trace the root cause of the problems caused by these bugs, because the problem is usually due to the integration of new code, Bugs that occur as a result of integration may have been embedded in the code for a long time before a prob

On the contrary, if the focus is on processes and systems, the direction of thinking is the same as in the above example. Which one is more effective? What is controllable? Do companies need controllers? Another typical problem is whether the coding review requires a review person or a review code? You can try to think about it in two ways. Let's see if this i

I have been working for more than two years, and I have never understood anything at the beginning, but I have gradually discovered the importance of knowledge, especially the accumulation of knowledge. So I learned how to accumulate knowledge and begin to record it since last year, record the problems encountered, how to solve them, and some instant ideas, and paste each work experience on my work desk. Programmers are good at thinking. Anyone who does this knows that the process of writing a p

The woods are big and all the birds are there, so is the app market. For example, there has been a period of time the image of the development of the blowout, all kinds of pictures social apps flooded the market. Many examples of short-lived apps are "come fast" and "you Sing to Me", with apps that focus on image processing or social elements. The reason, in addition to market saturation and other objective factors, more or some enterprises and developers anxious, envious market, to build a sens

Can not say that all the bugs are paper tigers, but often the kind of seemingly wonderful bugs, the cause is really simple, annoying you for a period of time, to find the truth and let you can't help a smile.

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
