computer generally does not involve confidential privacy and so on, but the virus is easy to install in an insecure network environment to your computer to achieve the purpose of the attackers. Relatively, Linux is relatively safe (the legend is that the MAC is the safest, but not the absolute security) its kernel will be updated in a timely manner, and in Linux to set operational permissions, monitoring ports and so is also very convenient. In addition, the server, the distribution of Linux se

Ugui this piece, the project at the beginning did not encapsulate it, resulting in the middle and later time planning to raise some requirements, and the original component does not have such a function interface! Thus wasting more time to achieve these completely universal functions! This is completely avoidable! I have seen many times that others have repeatedly implemented the function of a component is not want to do a good job in this package, so as to achieve the dry principle!For example:

that the company did not give you.6, interview to want all may ask your question, for example why come to Shanghai to find a job, answer can be: Before the company did not develop the future, want to big city development, or say girlfriend, relatives in Shanghai are can, there is the home company's leaving proof, this to prepare well in advance, this I will not say more, I don't know what I'm talking about.There are probation to sign the contract, some Provident fund, social Security to ask cle

much as possible.SummarizeEven if the thread pool is not used directly in the application, they are most likely to be used indirectly by the application server or framework in the application. The framework for Tomcat, JBoss, Undertow, Dropwizard, and so on, provides the option to tune the thread pool (the thread pool used by the servlet).Hopefully this article will improve the knowledge of the thread pool. By understanding the application's requirements, combining the maximum number of threads

Barmac Sand identified as simply to introduce we vertical roller mill, also referred to as vertical shaft impact crusher, Vertical shaft impact break, PCL sand making machine. Vertical Sand making process in comparison with classic sand, sand efficiency is enhanced drastically. Yield Square Sand Once the time, it is all astronomical, and PC

This article describes the importance of using byref/byval under. Net, and friends who need it can refer to All along, in VB6, parameters are routed by ByRef (that is, delivered by address).Under. Net (c#,vb.net), parameters are routed by default using ByVal (that is, by value) and have not been noticed.These days the optimizer found that using the default method (ByVal) is quite inefficient when transferring large variablessuch as the incoming param

of the queue, so that we can design an asynchronous system based on these characteristics.How to use these characteristics, so think, in the program execution will certainly have a lot of operations, some operations must always be executed, and some operations can be delayed, and some operations are not important and will take a lot of time, such as logging log, record game details, At this point we don't have to wait for the program to finish (and so there's a possibility of a problem, a lot o

Beginpath's role is simple, which is to start a new path, but it's very important to use the canvas drawing process.Let's look at a small piece of code:var ctx=document.getelementbyid ("Canvas"). GetContext ("2d"); Ctx.beginpath (); Ctx.rect (150,150,100,100); Ctx.fillstyle= "green"; Ctx.fill (); Ctx.rect (0,0,100,100); Ctx.fillstyle= "Yellow"; Ctx.fill ();Our code is not wrong, but it is two side length 100px Yellow square, instead of a green one yellow, this is why?In fact

Tenth, the website page link and the overall internal link quantity and the proportion need according to the website in the search engine weight actual situation to enter Yes. This is more difficult to grasp, if not master the site is easy to fall right. Set four principles for external anchor text links First, the home address for the site as a link, or page address, to enhance

This article illustrates the importance of Var in JavaScript. Share to everyone for your reference. The specific analysis is as follows: JavaScript's VAR function is to declare variables. In general, there will be no error, but some cases will have different results if they are not written. Let's look at the following example: This example above in the FF Chrome implementation will not be a problem, can output 1. But what about running in I
