Depressed, many things are unfamiliar, and it takes some time to create a project. First, write out the questions and steps. First, it is programmed based on registers.
1. Download The stm32 Firmware Library from the official website. I use 3.5
2. Create an stm32 folder (not for Storing Projects) and store the basic files required for creating an stm32 project. When creating a project again later, you only need to copy the folder to the corresponding project.
This folder contains the cmsis folde

Tomcat deploys multiple war package projects and configuration domain names
1. First, package the war project. First, use DOS to enter the project's root directory cd E:/XXX project/
2. Package command jar cvf XXX project. war */. (You can package all the jar files under lib or put the Jar files under lib to tomcat)
3. Okay. Here is our deployment.
3.1 put the project war package under the tomcat file D: \ apache-tomcat-6.0.37 \ webapps

If you want to set up a boot entry that requires sudo permission to execute, and you don't need to enter a password, then you need to add the program to /etc/sudoers . To line this, first execute sudo visudo , add the following line at the end of the file> All=nopasswd:/usr/local/cuda-6.5/samples/bin/x86_64/linux/release/devicequeryThen create a new item in Ubuntu Statup applications, and fill in the command barsudo /usr/local/cuda-6.5/samples/bin/x8

Two, operation steps
1, set the location of the data file for Logminer analysis
This is the process of setting the Utl_file_dir parameter, my example:
A, add the following line to the Initctc.ora file
Utl_file_dir=/u01/arch
B, open database

This article describes how to implement the JS third-level foldable menu. We will share this with you for your reference. The details are as follows:
. ASPX code:
Js file code:
Function doMenu (obj, strDeep) {var items = obj. parentNode. getElementsByTagName ("ul"); // obtain all the ul sets of object a under your node li. var itmUl; var deeps = strDeep; // strDeep is the level of the current menu if (items. length> 0) {itmUl = items [0]; aler
during operation, if only one data structure is allocated at a time, it will be allocated again when needed, which will compromise the performance. Therefore, the LMOs kernel uses a large number of memory cache pools to cache instance objects with those data structures. Memory is consumed in this way. I think 64 MB memory computers are also common if I go back for ten years. If LMOs detects that the memory is less than 64 MB, it will say that the memory is insufficient and then stop the convers
