AZ is the azimuth or horizontalRotation and EL are the vertical elevation (both in degrees). AzimuthRevolves about the z-axis, with positive values indicating counter-Clockwise rotation of the viewpoint. Positive values of elevationcorrespond to moving above the object; Negative values move below.View ([X Y Z]) sets the view angle in Cartesian coordinat

Init is one of the most indispensable programs in Linux system operation. Init process, which is a user-level process initiated by the kernel. The kernel will find it in several places in the past that used Init, and its correct location (for Linux systems) is/sbin/init. If the kernel cannot find Init, it will try to run/bin/sh, and if it fails, the boot of the system will fail.Linux 7 RunLevel (0: shutdown, shutdown mode,1: single-user mode,2: Multi-user mode,

Mesh database data is stored in a form similar to a network structure.

PrefaceLong time no update column, recently because of the project to contact the Pytorch, feeling opened the deep learning new world of the door. In his spare time, Pytorch trained the recent CNN model of State-of-the-art in image classification, which is summarized in the article as follows: ResNet [1, 2] Wide ResNet [

Today I went to a company, the name of the Atlas World Cut the crap and say: 1. Customize how a table field is implemented The first time I heard the question, I said it's easy to store all the tables and all the columns in the database table structure, and use the table to manage the tables and fields created by the user. After I answered this, the opposite is not very satisfied, said: If the field more how to do. And I'm doing this. Each query must first query to the required table, in the que

The collection of Python is not equal to the collection of other languages in a broad sense. Strictly speaking, a list is more like a collection, where set set is an unordered collection of non-repeating elements.* Can be understood as, there is no value only the dictionary of keys.

Inherit the first two articles, Eclipse fast-start hibernate--4. The Inheritance map (1) and the Inheritance map (2) have discussed the strategy for each Class hierarchy table (table per class hierarchy) with one table per subclass (table per subclass), which is essentially a table for each concrete class (table per concrete Class). Some of the repeated parts are not mentioned here, please refer to the first two articles.This strategy is simple, the a

number of connections that can be stagedIt works when MySQL receives very many connection requests in a very short period of time. If the number of connections to MySQL reaches Max_connections, the new request will be present in the stack waiting for a connection to release the resource, the number of that stack is back_log, and if the number of waiting connections exceeds back_log, the connection resource will not be granted. Setting the Back_log limit above your operating system is not valid.
