The following programming principles have made me a good programmer in the past years, and I believe that these principles can greatly improve the programming capabilities of any developer, allowing him to develop programs that are more maintainable and less flawed.　　I don't want to repeat myself -this is probably one of the most basic tenets of programming development, which

0. Write in frontFor the first contact with the Linux system, the installation of ns-3 seems unfriendly. But in fact, the installation process is not as complicated as it seems to be in a methodical way. In this paper, the installation process in the official Wiki is slightly combed, hoping to bring some convenience for beginners. As the description in the official Wiki is sufficiently detailed, there will

Now many friends have their own blog page, although they may not want to go to the wood to write a personal diary of the way, but to highlight the personality, publicity of the purpose of the ego, mostly similar. In fact, at this time, many of China's technology fans have looked to the wiki. After the network anti-Huang and Miko Mi, China's netizens have been familiar with the blog. As a new network concept, with the support of sophisticated technolog

Python crawler BeautifulSoup recursive fetch instance detailed Profile: The main purpose of crawlers is to crawl the content that is needed along the network. The essence of them is a recursive process. They first need to get the content of the page, then analyze the page content and find another URL, and then get the page content of the URL, repeating this process. Let's take Wikipedia as an example. We want to extract all the links from the Kevin Bacon entry in Wikipedia to other terms. #-*-C

This article mainly introduces detailed information about the Python crawler package BeautifulSoup recursive crawling instance. For more information, see The Python crawler package BeautifulSoup recursive crawling instance. Summary: Crawlers primarily aim to crawl the desired content along the network. They are essentially a recursive process. They first need to obtain the content of the webpage, analyze the content of the page, find another URL, and then obtain the page content of the URL, and

Preface The previous two articles talk about project management tools at the code level. This article will introduce the knowledge management tools, which are also part of project management. When it comes to knowledge management, what do you think? Woven network? Find a node? Yes, this is personal knowledge management. What about a project or an enterprise? How should enterprises build networks and find nodes. You must have heard of the word wiki. Co

Social networks have changed from fashion to the mainstream, and some suggest replacing the World Wide Web (WWW) with a giant global graph (ggg). Further, semantic networks (www.foaf-project.org) is the trend of the future network. The natural language Toolkit (nltk) provides a large number of tools for text analysis, including calculation of common metrics, information extraction, and NLP. The simplest way to answer "what people are discussing" is to analyze the basic word frequency. Grahviz i

This article introduces some of the principles in software design, which are learned after long-term experience. Every programmer should understand them. I believe it will be of great help to everyone in the process of software design. Don't repeat yourself (dry)Dry is the simplest rule and the easiest to understand. But it may also be the most difficult to be applied (because to do so, we need to make considerable efforts in generic design, which is not an easy task ). It means that when we di
