The CSS selector has a weight. When the style settings of different separators conflict, the style set by the selector with a higher weight will be used. If the CSS selector has the same weight, the style follows the proximity principle. The final definition of the selector adopts the style of the selector. If you ignore the CSS selector weight, it will cause unexpected minor problems.Requirements and Solutions CSS selection operator weight is very important Now we need to set the word "importan

the relevant information he said, and I only looked at the interface. At that time, I only proposed to use setTimeout or setInterval to avoid this problem, however, the last time I used a multi-threaded Demo was too long and a bit vague, and I was not sure about it. So when I went home, I quickly pulled out the previous Code and sorted out the answer, as shown below: The code is simple, so I am too lazy to write comments. The following are the number

vswitch, it hides a serious risk in your virtual LAN. A site can easily prove that it is using an 802.1q-encapsulated switch, thus creating a relay link and becoming a member of all Virtual LAN. Thanks to Cisco's latest IOS operating system, this security vulnerability has been fixed. To avoid possible Virtual LAN jump attacks, do not use the "dynamic" mode at the interface level, and set the network to "relay" or "access" type. Address Resolution Pr

It is often appropriate to reuse a single object instead of creating a new functionally equivalent object each time it is Needed. Reuse can both faster and more stylish. An object can always be reused if it is immutable.String S=new string ("no"); DON "T do this!The statement creates a new String instance each time it is executed.String s= "yes";This version uses a single String instance,avoid creating unnecessary objects.

Original: Use Configsource in the Web. config file to avoid dynamically modifying Web. config to cause ASP. NET Restart (Add a config file to manage user data)As we all know, after modifying the configuration file Web. config in ASP. NET, it causes the application to restart and all sessions (session) are lost. However, the application configuration information in the configuration file is the best choice, in the background to modify the configuration

Recommendation 31: Avoid unnecessary iterations in LINQ queriesWhether it is a SQL query or a LINQ query, it is more efficient to return results immediately than to search all the results and return the results.Example code: classMylist:ienumerable { //to demonstrate the need, a collection of elements is simulatedlistNewList() { NewPerson () {Name ="Mike", age = - }, NewPerson () {Name ="Mike", age

Recommendation 8: Avoid providing an explicit value to an element of an enumeration typeIn general, it is not necessary to provide an explicit value to an element of an enumeration type. One reason to create an enumeration is to replace the actual numeric value. Incorrectly setting an explicit value for an element of an enumeration type can lead to unexpected errors.If you add an element to the enumeration type week in recommendation 7, the code looks

Item 28: avoid returning the "handles" ("handle") of the internal component of the object ") By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ Suppose you are working on a rectangle-related application. Each rectangle can be expressed in the upper left corner and lower right corner. To keep a rectangle object in a small State, you may decide which points in the rectangle area should not be stored i

Introduction Any ProgrammingCodeReuse. Otherwise, a newProgramOr if you want to write a new function, you can take a break, but code reuse is also good or bad. The next two articlesArticleWe will discuss code reuse. The first article avoids the article, which means we should avoid using these models as much as possible, because there are more or less problems. The second row is the recommendation article, it refers to the recommended mode, which is g

The following is a list of precautions that developers should avoid when using the Windows NT Device Driver: Do not return status_pending through the scheduling routine without marking I/O Request Packet (IRP) suspension (iomarkirppending. Do not call kesynchronizeexecution through the interrupt service routine (ISR. It causes a system deadlock. Do not set deviceobject-> flags to do_buffered_io or do_direct_io. It will disrupt the system and event

"When two horses pull a car together, the horse behind them will be less lazy. When the master sees that a horse can also pull a car, the horse behind will stay at home for zero work. The horse on the front does a horse's work, and the food is still the grass. The horse on the back does not need to do heavy work, and the life is comfortable, and the 'profit' is not lowered. Of course, the horse on the back is very proud. At the end of the year, our house was ready to entertain guests during the

Avoid over-streamlining temporary variables-refactoring During the refactoring process, a problem occurred in my code and an endless loop occurred! An important means of refactoring is to remove the hateful temporary variables and change them to method calls. This is an idea that Martin Fowler emphasizes. A major means and goal of refactoring is to extract methods.The code of a large segment is divided into many micro functions. A major obstacle to

Objective C blocks: is there a way to avoid 'self 'being retained? I discussed this topic with Apple support, and they told me what I had expected: Currently, there is no way that wocould let me tell the block that it shoshould not retain self. however, they offered two ways to work around the problem. The first wocould be to pass self as an argument to the block rather than a block variable. The API wocould become: [Self addeventlistenerfortype: ad

When the following conditions occur, Android it will show ANR dialog box:Response to input events (such as keystrokes, touch-screen events) exceeds 5 sec Intent Receiver (intentreceiver) The second is still not finishedThe Android app runs completely in a separate thread . This means that any running in the main thread,Operations that require a significant amount of time will cause ANR. So how to

Go is a feature that is automatically recycled with memory, so memory is generally not compromised. However, there is a leak in the goroutine, and the leaked goroutine reference memory cannot be recycled.In the following program, the background goroutine enters the natural number sequence to the pipeline, and the output sequence is in the main function. But when break jumps out of the for loop, the background goroutine is in a state that cannot be reclaimed.Func Main () { ch: = func () We can
