1th: How to create a "seam". Seam (seam) is a concept that needs to be known.2nd, avoid writing hard-to-test code when building objects.This article is the 3rd chapter, which describes the dependencies and Dimitri laws.Dimitri (Law of Demeter)Or use the example of building a car. When producing a car, you need a tyre, what type of tyre is needed to assemble it, the tyre is requested, and the person concerne

to writing the answer to the ultimate question of the universe file .One point to note: It is best to use a Qt integer for reading and writing, such as in a program qint32 . This ensures that the same behavior can be found on any platform and any compiler.Let's look at an example of how Qt stores data. For example char * , a string that, when stored, stores the string first, including the length of the (32

The content comes from Intel assembly language programming (Fourth Edition) Chapter 11th -------- 32-bit windows programming. We should first write the content into the file (if there is no file, a new file will be created), and then read the content from the file. First, let's take a look at writing data to a file: Title using writefile (writefile. ASM) Include irvine32.inc . Data Buffer Byte "this t

js|jscript|vbscript|web| programs use VBScript and JScript to write Web applications My heart is flying The motivation to write this article is to see the discussion of VBScript and JavaScript, as well as another piece of similar articles, feel the need to put together the idea of the:-), and the work I produced some of the experience out and share with you, hope to help. Of course, the level is limited, mistakes are unavoidable. Active Server pages is an important part of Microsoft's Window

XMPP protocol for instant messaging underlying writing (2) -- IOS XMPPFramework Demo + analysis, xmppxmppframework I hope This is a new day! Before reading the code, I think you should first sort out your mood and let me say a few words: First, I hope that you will read this blog in the morning and then start to operate it. If you only read the blog and do not compare the project yourself, it will not be very helpful. One day is in the morning, so wit

Quick sort:Algorithm principle fast sorting algorithm operation is as follows:Quick Sort (Quicksort) is an improvement to the bubbling sort.1 set two variables I, J, when the sort begins: i=0,j=arr.length-1;2 with the first array element as the key data, assign the value to key, namely key=a[0];3 forward Search from J, that is, after starting the forward search (j--), find the first value less than key A[j], will a[j] and A[i] interchange;4 Backward search from I, that is, t

I will upload my new book "Write CPU by myself" (not published yet). Today is 12th articles. I try to write them every Thursday. Change the title of "self-writing processor" to "self-writing CPU". 4.3 verify the implementation of openmips 4.3.1 instruction memory Rom This section checks whether our openmips is implemented correctly, including: whether the pipeline is correct and whether the Ori command is

Flash, as a powerful animation tool, can also easily achieve handwriting effect. Now, we use Flash5.0 (Chinese version) to make handwriting effect, the following steps: 1. Create a new file in Flash. 2. Modify movie properties in "Modify → film ...". 3, press CTRL+F8, new components, named "Brush", pencil tool to draw a brush. Figure 1 4, with the type tool, input "dragon" word, the font can be set to Xingkai, the font size value is "300" (oneself input), the color is black (Figure 1).

• BackgroundWhile in the student dog era is also during the summer vacation, we just good use this time to learn another for I have not touched the field, that is, web programming. Although I wanted to be an Android engineer, the cross-platform of Android development now makes Android programming no longer confined to native development. I have been learning Android for almost a year, remember from last summer, I took the school lectures on the side of the book to learn the Android Foundation. L

Emmet plug-ins are commonly used in writing and emmet plug-ins I read some documents about the Emmet plug-in writing. How can I write it so long. Actually, I know a few rough points, and I can write my work in combination with my practice. Miscellaneous In my previous article [Discovering the New World Today: haml and Emmet], I wrote my first thoughts to myself. Some people read my blog and comments. Althou

Since the last summary has been a full one months, after busy half a month of work after a busy afternoon I can finally make this phase of the summary. First of all fortunately in the classmate's recommendation I successfully found a job and at the beginning of the month 3rd formally to work, this is very grateful to him, let me remove the money bag flat astringent distress and the rush to apply everywhere. And then back to the chase, the first half o

you want to apply to the current project, then you need a 3rd level. The goal is to be able to reproduce (re-implement) papers under the same hypothetical conditions. At the same time, pay attention to the corresponding code on the GitHub, jump to the program can accelerate understanding. Comparing the results you reproduce with the original paper, you can really understand the innovation of an article, as well as its implied premises or assumptions.
