using them as a side-by-side concept is clearly misguided from the start-and it is this misleading that makes most people focus too much on the tactical aspect of polymorphism, even to the point of almost malicious exploitation, while ignoring the strategic aspects of the problem, This makes it easy for the software to be designed as a thin piece of excrement (which will be discussed in detail later).In practice, the first meaning of inheritance (rea

One-wire Demo on the stm32f4 Discovery BoardSome of the devs at work were struggling to get their software talking to a Dallas 1-wire device. I remember doing 1-wire comms back on the 1990s, but I hadn ' t do any 1-wire lately and all of my old code is for Proces Sors I no longer had running. But I had a weekend free, so I figured I ' d pulling some old 1-wire devices out of the junk bin and write a bit o ' code ...The 1-wire protocolThe Dallas (now M

Development Method of an organization, and the business value is reflected in it. For a long time, our programmers have been good technical thinkers. We are always good at solving project problems from a technical perspective. However, whether a software system is truly available is reflected by the business value it provides. Therefore, instead of sticking to technologies that are never enough to learn every day, why not think about our focus in the direction of business value provided by soft
developing complex models, but they require direct access to the information stored in the Data warehouse relational structure. In the face of such applications, you must consider the capabilities of the Data warehouse. A few users can easily consume 50% or more of their resources on the Data Warehouse platform at peak times. Resource consumption is so huge because of the complexity of the data access process and the large amount of data processing.4th stage: Operational orientationThe 4th phas

includes a function reference to create an argument object. So how should we use it?The Arguments. callee method allows an anonymous function to easily point to itself.Repeat is a function that carries a function reference and two numbers. The first number is the number of function calls, and the second number is the interval of each call, in milliseconds.
function repeat(fn, times, delay) { return function() { if(times– > 0) { fn.apply(null, arguments); var args = Arr
, an anonymous function is returned to re-run the originally called function. Finally, use setTimeout and an anonymous function to implement delayed execution.
As a simple description, for example, you can write the following simple functions that provide strings and bring up a warning box in a common script:
The Code is as follows:
Function comms (s ){Alert (s );}
Now, I changed my mind. I want to compile a "special version" function that repeat

The repeat function uses arguments. callee to obtain the current reference. After it is saved to the self variable, an anonymous function is returned to re-run the originally called function. Finally, use setTimeout and an anonymous function to implement delayed execution.
