ingress filtering

Objective In this section, we will continue to talk about indexing knowledge, in front of our clustered index, nonclustered index and overlay index, in which there is also a filtered index, through the index filter we can improve query performance, short content, in-depth understanding. Filter indexes to create nonclustered indexes on query criteria (1) The filtering index is a new feature of SQL 2008 that is applied to some of the rows in the tabl

Netfilter/layer7By default, NetFilter can filter only two or three or four layers of data, but the application layer of data (such as QQ, thunder video, etc.) is not filtered out. We also know that NetFilter is working in the kernel, so the data that NetFilter supports filtering LAYER7 application layer protocols must be recompiled. Because Iptables is a rule-editing tool, you also recompile iptables so that it can support the authoring of LAYER7 appl

There is such a problem that mysql queries whether the data queried by the left (right) join filter condition on and where in mysql is different.

At the beginning of the guide, we said that data filtering is the cornerstone of Web application security in any language, on any platform. This includes checking the data entered into the app and outputting the data from the app, and a good software design can help developers: Ensure that data filtering cannot be bypassed, Ensure that illegal information does not affect legitimate information, and Identify

Objective: To introduce the use of a common recommendation algorithm (user collaborative filtering).Application scenario: After the XXX project runs for a period of time, there will be a lot of video information in the system, and usually the app gives the user push messages (1-3/day),Then this requires us to push more effectively based on the user's behavioral characteristics.Tool Introduction: The use of mahout collaborative
