Python crawler practice (5) -------- Zhaopin network and python Zhaopin Network A few days ago, I helped my colleagues crawl some information about data analysis jobs on the Internet by Zhaopin. He said that he had to perform some data analysis. Now he has helped him crawl the job. I originally wanted to use Scrapy for crawling, but I don't know why the crawled d

some time ago also learned a lot of network-related knowledge, but also through a variety of practices. But it never starts with a real workout from scratch. Please try it today. The following is a detailed record of this process. This includes a partial understanding of the network and a record of the problems encountered. Practice Content and Purpose:1, using t

Absrtact: The authors share the calico changes (including components, documents, and CALICOCTL) that are seen by the user, Demo some simple examples, and Macvlan to do a comparison to explain the principle of the summary of the appropriate calico to use the scene. Good evening, I am a few people cloud Shangxiangyang, next to share with you the theme is "Container Network calico Advanced Practice." Distance

Network Application and client software When it comes to mobile web apps, the first thing we think about in the last few years is WAP applications. Recently with the market on the mobile phone's programmable ability more and more strong, mobile phone software development platform and industrial chain gradually mature, mobile phone network application software gradually more up, such as Mobile QQ, PICA, pal

models, the above features can be used directly, whereas for linear models, it is necessary to do some batching, normalization, and so on for the eigenvalues to make the eigenvalues a continuous or 12 value between 0~1.SummarizeBased on the data, with the algorithm to carve, only the two organically combined, will bring the effect of ascension. For us, the following two nodes are milestones in our optimization process: Merging candidate sets: Improved recommended coverage, versatility,

booted to the private Internet Protocol (IP) address of another host. cause : One of the cluster hosts is configured with a master priority identifier equal to 1. solution : Do not configure any cluster hosts with a master priority identifier equal to 1. Use a number greater than 1. For more information, see Configure Network Load Balancing host parameters. You cannot create a

algorithm, added a program for collecting dynamic weights and fed back it to the Load balancer's scheduling system in real time. Practice has proved that the use of dynamic balancing has improved the overall throughput of the cluster system, especially when the performance of each node in the cluster is different and the network service programs provided by the cluster have diversified resources, the negat

Log System Common logs are typically stored in/var/log: You can roughly divide the logs into two categories based on the service object: System log, Application log. System log is mainly for the system built-in program or system kernel such as log information such as Alternatives.log, btmp and so on, the application log is the third-party application of our installed log such as TOMCAT7, apache2 and so on. references Getting Started with Linux Basics (new version)
