Recently, many viruses with weak passwords have become popular on the Internet. For example, the Worm. Dvldr Worm, which has been very popular some time ago, is a typical one. One thing these viruses have in common is the use of batch processing for the ipc $ connection, so as to guess the Administrator's password to control the server. A virus consists of several files and several complex batches. Batch pr
JDBC It provides a database batch capable of processing, in bulk data Services (extras, deletions, etc.). ), you can significantly improve system performance. I have a link to a project. In the absence of batch therapy, delete 5 about half an hour of data, the transformation, the use of batch processing method. Deleting 50,000 data will not be more than 1 minutes
JDBC provides the ability of database batch processing to significantly improve the performance of the system in the case of large volume operations (additions, deletions, etc.). I have contacted a project, in the absence of batch processing, delete 50,000 data about half an hour or so, and then the system to transform, using batch processing method, delete 50,00
In machine learning, the gradient descent (Gradient descent, GD) algorithm only needs to calculate the first derivative of the loss function, the calculation cost is small, it is very suitable for the training data very large application.The physical meaning of the gradient descent method is well understood, that is, the line is searched along the gradient direction of the current point, and the next iteration point is found. But, why does it derive the GD algorithm of

Batch import data to Elasticsearch Based on Spring Batch, batchelasticsearch
1. Introduction

The variables in the batch, I divide him into two categories, "System variables" and "Custom variables"
Let's now take a detailed explanation of these two variables!
First, System variables
Their values are automatically assigned by the system according to predefined conditions, which means that the variable systems have defined values for them,Don't need us to assign him a value, we just need to call it! I'll list them all!
