7-Zip is a compression software that claims to have the highest compression ratio today. It not only supports the unique 7z file format, but also supports a variety of other compression file formats, including ZIP, RAR, CAB, GZIP, BZIP2, and TAR. The compression ratio of this software is 30-50% higher than that of common ZIP files. Therefore, it can compress files compressed by WinZip 2-10%.
7-Zip Main FeaturesThe algorithm is updated to increase the
This is my second bad hard disk. The last time was about 10 years ago, it took 3500 hard disks (40 Gb capacity) to be sent to South Korea to restore data. Later, I learned a lot about backup.
As time went by, everything went normal and began to relax again. No, the hard disk in the new notebook stores all my data and is completely finished one day.
This luck is not bad. I just performed a backup half a month ago, but I lost two weeks of code work.
This time, I didn't spend 3000 RMB. Of course, i

A Web crawl framework developed by Scrapy,python.1, IntroductionThe goal of Python's instant web crawler is to turn the Internet into a big database. Pure Open Source code is not the whole of open sources, the core of open source is "open mind", aggregation of the best ideas, technology, people, so will refer to a number of leadingproducts, such as Scrapy,scrapinghub,Import.io and so on.This article briefly explains the architecture of the scrapy.

Feature matching can be roughly divided into 3 steps:
Extraction of features
Calculate feature vectors
Feature Matching
For 3 steps, encapsulation is done in the OpenCV2. All feature extraction methods implement the Featuredetector interface, and theDescriptorextractor interface encapsulates the extraction of eigenvectors (feature descriptors), and all eigenvector matches inherit Descriptormatcher interface. Simple feature Matching intMain () {Const stringImgName1 ="x:/
