lambda:New Thread ((), System.out.println ("t2222"));Summary:1. Behavior parameterization, is a method to accept a number of different behaviors as parameters, and use them internally, the ability to complete different behaviors.2. Behavioral parameterization allows code to better adapt to changing needs and reduce future workloads.3. Passing the code means passing the new behavior as a parameter to the me

Recently need to use the text of the phonetic similarity calculation, looked at the HANKCS great God in the HANLP through the AC automata to achieve pinyin storage, want to turn it into a Python version. Start chewing on the AC automaton. AC automata are established in Trie tree and KMP string matching algorithms. First chew the trie tree. About the concept of trie tree, http://blog.csdn.net/v_july_v/article/details/6897097 This article is very good, but also attached to the suffix tree. All I h

OpenGL's top rookie question read a book "OpenGL three-dimensional graphics system development and application Technology", however, the function involved in the Glut.h file is not properly connected, the typical error is as follows:------started build: Project: Gears, Configuration: Debug Win32-- ----1> is being linked ... 1>gears.obj:error LNK2019: unresolved external symbol ___glutinitwithexit@12, which

value, the lower the value, and the higher the value. For example, if 130 is converted to binary 1000,001 0, a total of 8 bits are required. one byte cannot be expressed. Therefore, two bytes are required. The first byte represents the last 7 bits, in addition, the highest position 1 indicates that there is a byte next to it, so it is (1) 0000010, the second

In the past two days, I took the time to summarize/sort out the actual encoding methods and usage of various encodings in Java applications. I will record them here for future reference. In order to form a complete understanding and in-depth understanding of text encoding, in order to deal with various problems encountered during Java development, especially the garbled problem, I think it is better to make up a series to describe and analyze, including three articles: First Article: Java charac

the sequential relationship.Step 1:The preceding algorithm has two resources: the boat ride scheme and the number of people on both sides of the Strait. There are up to five boat hailing schemes. Here, a char-type number is used to map it. That is, the first four digits of the 8-bit binary number are interpreted in the complement code format to represent the number of servants, the last four digits represe

Final effect Use Photoshop Tutorial to pull out the soft pink non-mainstream effect of the exterior character photos 1, open the original material, create an optional color adjustment layer, slightly adjust the background and color of people's clothing, yellow and magenta adjustment, parameter settings such as Figure 1, 2, the effect is

Cyan and yellow are more easily paired colors. The processing method is also relatively simple. Only need to turn the noise in the screen into cyan, yellow. Then soften the process appropriately. The character part only needs to be appropriately ruddy.Original Final effect 1, open the original material, create an optional color adjustment layer. Because you want to add

Magenta is a more vivid color, the best time is to mix the background and characters separately, the background can be in lab mode, with the curve quickly color. Later the appropriate beautification of some characters, and then rendering some complementary color and so on.Original Final effect 1, open the original material, create an optional color adjustment

The same is the use of channels and calculation of skin and whitening, but the author later added a gradient map to enhance skin color contrast, you can better highlight skin texture.

What is the difference between Unicode, UTF-8, and iso8859-1?Will take "Chinese" two words as an example, by looking at the table can know its GB2312 code is "d6d0 CEC4", Unicode Encoding "4e2d 6587", UTF code is "E4b8ad e69687". AttentionThese two words are not iso8859-1 encoded, but can be "represented" by iso8859-1
