ASP. NET Identity and OAuth
Magicodes. NET supports ASP. NET Identity and OAuth protocols. without writing a line of code, you can easily integrate QQ, Microsoft, Google, Facebook, Twitter, and other OAuth interfaces.

Figure 1 retention time and Creation Time
The same module designed by FPGA often containsCombination logic and time series logicTo ensure that the data at these logical interfaces can be processed stably, it is very important to establish a clear concept of the Creation Time and retention time. The following are some questions about the concept of building time and holding time.

Figure 2 shows a basic model for a unified synchronizatio
Synchronous bus communication
The communication parties control data transmission on a unified time scale, which is called synchronous communication. This public clock can be sent to each component (device) by the CPU bus control component, or each component can have its own clock generator, which is usually issued by the CPU bus control component, all components sent to the bus; they can also be sent by their respective time series generators, but must be synchronized by the clock signals sent
The template engine xtemplate is an engine similar to the T4 design. It basically functions the same as T4 (the template syntax is fully compatible with T4, And the template header instruction is partially compatible ).
You can design a template engine for multiple scenarios, such as code generators, website templates, and email templates. That is, you must be ab
Javascript Object comparisonComparison OPERATOR: = ,! =, = ,! ==, >=, = Always try to compare them straight, if the types are different, always try to convert.=== Comparison same, comparison without conversion= If it is a basic type (string, number, boolean), compare their values,Var a = "123 ";Var B = 123;Then (a = B) = true;(A = B) = false;If it is object, array, function type, compare their reference. Only when their reference is equal is true.Function Point (x, y ){This. x = x;This. y = y;};
One.Wait and sleep methods are somewhat similar, and we now want to describe them and differentiate them.The wait method is in the object class, and there are two forms, wait () and wait (long timeout), and we focus on the latter.The parameter indicates that the wait method can wake up.The difference between waiting and sleeping, sleep can wake up, but waiting may be endless.The two are an object method and one is the thread method.Sleep can not wake up, do not need to be called. Sleep holding t

stuttering in front of the drinks shop counter, the boss warmly greeted: "Drink a bottle?" , "stammered hurriedly said:" I ... Drink... Drink ... ", the boss quickly opened the cans handed to stutter, stuttering finally suppressed his words:" I ... Drink... Drink... I can't afford to drink it! ”。 In this joke, the owner of the beverage shop had a dirty reading of the stutter .Reading "Dirty" data means that transaction a modifies a data, and writes it back to disk, after transaction B reads the
owner of the beverage shop had a dirty reading of the stutter.A transaction reads the change data that the B transaction has not yet committed and operates on the basis of this data. If the B transaction happens to be rolled back, then the data read by a transaction is not recognized at all. Look at the dirty read scenario that is raised when the withdrawal transaction and the transfer transaction are concurrent:

Because only with notify, it is easy to wake up the thread only, causing all threads in the program to wait. public class Test{public static void Main (String args []) { Resource r = new Resource () ; Producer Pro = new Producer (r); Consumer con = new Consumer (r); Thread t1 = new Thread (PRO); nbs P Thread t2 = new Thread (con); thread t3 = new Thread (PRO); thre
