Preface This self-examination, small series of "operating system introduction" and "operational research." This self-examination to the small part of the feeling is to study must go heart, must read three times, must pay attention to methods. Introduction to Computer systems Before learning the operating system, you must first understand the hierarchy of the computer system. The most inner layer of compute

Parallel hybrid design Multiple recommendation engines, how to fuse together? 2.1 Cross-mixing multiple results of multiple recommendation engines, cross-merge into one result: first engine first result ranked first, second engine first result ranked second ... 2.2 Weighted mixed linear weighted combination, one weight per engine, weight normalization 2.3 switching mix when in some cases w

Basic idea: The data is divided into training set and test set, training model with training set data, test model with test set data. The Division of Training set and test set can be by the dimension of time, or by the dimension of the crowd. Risk: There may be biases for some methods.Using historical data to evaluate the data into training set test set and N-fold cross-validation according to Time dimension.There is also the direct use of human evaluation. However, the cost is larger, not on th

Introduction to Linux Namespace We often hear that Docker is a virtualization tool that uses Linux Namespace and cgroups, but what is Linux Namespace how it is used in Docker, where many people are confused, Let's begin by introducing the Linux Namespace and how they are us

record when writing or revising a file. Therefore, when data inconsistency occurs, you can examine the log record block directly, and you can quickly identify the problem. Linux EXT3 is a file system that supports logging capabilities. It has also been said that since the disk is much slower than memory, Linux does not immediately update the modified data in memory to disk after modifying the data in me

associated to the same inode number, so the two files represent the same file, and the reference count is 2. The inode for the Symbol_link file is different from Test.file because Symbol_link is a standalone file, but it is a connection file to Test.file, and you can observe that the Symbol_link file length is 9 bytes. is actually test.file the file's filename length.Finally, explain the number of connections to the directory. Each time a new empty directory is created, the number of connection
