just on your limit, that is, the things that are likely to fail for you. If you do not experience some failures, you may not grow. You must constantly challenge yourself and surpass your limits.
Such challenges are sometimes encountered at work, but not necessarily. Exercise is separated from professional work, which is often called code Kata in programming ).
The concept of code kata was proposed by David Thomas, who is one of the authors of "Programmer cultivation: from small workers to exper
Java coding comprehension keywords: Java coding, Unicode, getbytes () come from my notes: youdao note-Java coding understanding the coding involved in various programs is nothing more than the encoding of source code files, the encoding of the string in the program. java is known as an international language because it
The second piece records the code.Encoding: A set of n-bit binary codes used to represent different numbers or other events, called an encoding.Code word: A specific n-bit combination of the exact meaning, called the code word.In short, it is understood that coding is a way of expressing binary number sets.1, decimal number of binary codethe binary encoding of the ① decimal number is a binary representation of 10 decimal digits 0~9.② decimal number of
Introduction
Recently SVMs using spatial pyramid matching (SPM) kernel have been highly successful in image classification. despite its popularity, these nonlinear SVMs have a complexity in training and O (n) in testing, where N is the training size, implying that it is nontrivial to scaleup the algorithms to handle more than thousands of training images
The cost of Nonlinear SVM is huge.
In this paper we develop an extension of the SPM method, by generalizing Vector Quantization to Spar
H264 is a new generation of coding standards, high compression high-quality and support a variety of network streaming media transmission is known, in terms of coding, I understand his theoretical basis is: reference for a period of time, the statistical results show that in several adjacent images, there is generally a difference in pixels only 10% of the points, The difference in brightness does not chang
A, the material coding management rules need to reflect as much as possible material categories.The large category of material allows us to have a direct judgment on the category of the item. For example, we use mobile phones every day,If we see number 139th, we know it's a mobile call. The classification principle of large class is often: The first code: produceProducts, semi-finished products, raw materials, excipients, low-value consumable, mainly
Distance from Huawei Wireless Seventh edition of the game has been nearly one months, although the heart has been thinking about a good summary, but before due to some other reasons have not been summed up, today while to open this summary of the reasons for the meeting, the rationale, only for the next time to do better.In the one months before the seventh session of the Huawei Wireless Coding competition, I also participated in the code competition
The development of software is divided into 6 main steps: Planning, requirement analysis, software design, program writing, program testing, operation and maintenance. The previous summary has already said the development plan, the demand analysis, the software design These four steps, now we say the procedure to write.The so-called program writing, is coding. Refers to the detailed stage of the design of a certain programming language into the comput
Having been exposed to such a long time web design has come across a lot of things related to coding. But today again encountered a garbled, fortunately search to solve.
Here are some of the places I know to be aware of coding:
1.

2.
How the document is encoded when it is saved
3.
How the database is encoded (set when defining a database or table)
4.

In the first two articles, we learned about Android memory, including how to use memory reasonably, and how to locate a problem when a memory leak occurs. So the knowledge of memory is discussed here, and today we will learn some techniques of performance coding optimization.Here first of all, the coding optimization techniques discussed in this article are all part of "micro-optimization", meaning that eve
Python coding problem is basically every novice will encounter the threshold, but as long as the full grasp of the jump over the pit, million change it, this is not recently I have encountered this problem, come together to see it.The cause of the matter is review colleague to do an upload function, see the following section of code, SELF.FP is an uploaded file handlefpdata = [line.strip().decode(‘gbk‘).encode(‘utf-8‘).decode(‘utf-8‘forin self.fp]data
Applications Library
While you may think your ideas are unique and special, there is a great chance that you are trying to write code that has been written by a number of other programmers. To help developers overcome these hurdles, PHP developers regularly contribute PHP extensions and application libraries, such as the famous pear. The pear contains 560 packages that provide fast solutions such as caching, encryption, user authentication, and payment processing. You can always find the righ
Remember to learn python when learning the crawler, often encountered coding problems (in fact, in python3 coding problem has been very little ...) ), with the requests library is very convenient to solve these problems. Recently, there are programmers who have co-learned python to write an e-book website, want the relevant crawler, so I went to try ... Of course, the first step to meet the "
into the fourth chapter, the main point of this article is coding (that is, serialization ) and code upgrade some scenarios, to comb the memory involved in the process of encoding and decoding. The current mainstream codec is from the Apache Avro, from the Facebook Thrift and Google protocolbuf, in this article, We will also comb the advantages and pain points of various codes.

Indentation of 4 spaces (the editor can do this), no tap, no mix of taps and spaces.2 The maximum length per line is 79, the line break can use backslashes, prefera
In the python source code file, if you are useful to non-ASCII characters, you need to make a declaration of character encoding at the head of the file, declared as follows:
# code : UTF - 8
Because Python only checks for #, coding, and encoded strings, you may be able to see the following declarations, which some people write for reasons such as aesthetics:
#-*- coding:utf-8 -*-
Common
Here is a summary of several cases that will lead to coding problems, and explain one by one ...Case one: Chinese output is garbled?
# Python Version: 2.7.6
>>> string1 = "I love Fish C Studio"
>>> string1
' \xe6\x88\x91\xe7\x88\xb1\xe9\xb1\xbcc\xe5\xb7\xa5\xe4\xbd\x9c\xe5\xae\xa4 '
>>> Print string1
I love Fish C Studio
>>> string2 = "I Love FISHC"
>>> string2
' I Love FISHC '
Q: Why can't I display
Python supports 3 kinds of code declarations, commonly used to see the following two1.# -*-coding:utf-8-*-This is written to be compatible with Emacs's code declaration.2. Short, but Emacs cannot be used # coding=utf-8A little shorter, but Emacs can't be usedThe reason to declare an unencrypted type is mainly the problem of Chinese error.At the beginning of the Python file (typically the first or second line), use the encoding used to describe your
