Programmer have this to say about the broken Window theory:Don ' t leave "broken windows" (bad designs, wrong decisions, or poor code) unrepaired. Fix each one as soon as it is discovered. If There is insufficient time-to-fix it properly, then board it up. Perhaps you can comment out the offending code, or display a "not implemented" message, or substitute dummy data instead. Take some action to prevent further damage, and to show this you ' re on top of the situation.We ' ve seen clean, functi

the regular expression must end with B, so the regular expression can match the Axxyyzb in the string above. Summarized as follows: 1. Add a question mark (?) after a repeating quantifier. Can form an inert match.2. The lazy match will match the characters as few as possible, but the entire matching pattern must be met. Two. List of lazy qualifiers: The following is my profile In fact, greed and inertia is easy to understand, from the literal meanin

inertia writer thread regularly checks the size of the SQL Server idle buffer list. When this value is too low, the inertia writer scans the entire data cache and ages all unused pages for a period of time. If you find a dirty page that has not been used for a period of time, the inertia writer writes it to the disk and deletes it, And then marks the memory spac

I resigned in middle June, and it is almost four months now. I have been playing for two and a half months at the beginning, and I am not prepared for the interview. A lot of opportunities are wasted, and I also realized that my technology is weak. To the point where no one cares, let's be honest. It's really not a taste of yourself. I have been studying Linux C Programming in recent days. I hope to find a job as soon as possible, so that I can learn what I don't know. The four years of unive

that controls the size of the window in a scrolling view, while Uiscrollview is the core component of the scrolling view that controls the scrolling function without the windows of the Uiscrollview component being scrolled.1.ContentOriginThis is the starting point for what the scrolling view contains, and the default setting is the upper-left corner.2.MovementThe scrolling direction of the scrolling view, which is the direction in which the content is moved. Altogether there are 4 different way

values to implement the corresponding functions. If we add other parameters, we should write this: $ ("#main").

OK, let's describe the detailed parameters below. * **se

JavaScript AJAX-based Inert Loading Function, javascriptajax Some memory in JS only needs to be executed once. For example, browser type detection is the most commonly used function, because we need to detect the built-in XHR of the browser when using Ajax. We can record the type during the first detection, and do not need to check the browser type when using Ajax later. In JS, even if there is only one if statement, it is always more efficient than the statement without if. Common Ajax MethodCo

MG Full name is motion graphic motion graphics, is now very popular, but not all MG video can make the graphics movement perfect, I summed up a bit, in the MG animation how to do the graphics movement comfortable and not awkward, there are mistakes, but also please forgive me to add. 　　First, the important acceleration In the MG animation, uniform motion is usually rejected. Uniform motion in the real life is not much, on the contrary, we live in the world everywhere is the interaction of for
