Nutch 1.3 Study Notes 11-1 page scoring mechanism OPIC--------------------------------------1. Page scoring mechanism of nutch 1.3 At present, nutch1.3 uses OPIC as its webpage score algorithm by default. However, the PageRank-like algorithm has been introduced to make up for the shortcomings of the OPIC algorithm, currently, the OPIC algorithm is implemented as

In the mysql field definition, x in INT (x) only indicates the display width. The optional display width rule is used to fill up the width from the left when the display width is less than the specified column width value. The display width does not limit the range of values that can be saved in the column, nor the display of values that exceed the specified width of the column. Therefore, the definition of x has nothing to do with the storage space. It is 4 bytes.As an extension of the SQL stan

thought:question : Can AYSNC be used for recursive calls, such as a crawler, a function that iterates through all the file information in a folder? Why?SummarizeThis is another cliché of technology sharing, but after writing it, the process management of asynchronous operations becomes clearer. AYSNC is good, but it is not omnipotent, it is useless for the code that repeats itself, because the callback that restricts the task is once. Follow-up, there will be opportunities to continue to study
