fedora 24 cannot modify keyboard delay and rate

昨天终于搞定了ycm对c++11的支持…. 嘛，17都快出来了，我竟然连11都不会用。 不过突然把所有的11特性给我也没办法全部吸收。 所以在这里记录下用过的c++11的用法。

一般有两个 1static int a; 2int b; 3void func(void) 4{ 5 static int c=0; 6 int d; 7} 在这里，a与b都是全局变量，二者的区别是，b可以被别的文件使用，a只能在本文件中使用，这是static对全局变量的作用。 ** c和d的区别是，d是一个自动变量，func函数执行完后，d会自动被释放。但c却不会被释放，下一次调用func函数时，c的值会保留上次的值继续使用(而不是初始值0，初始化只会在函数第一次被调用的时候执行)**

Open up the Terminal (Alt + F2 > Terminal). Remove OpenJDK installation. 1sudo apt-get update && apt-get remove openjdk* Download Oracle JDK from here. You are looking for a linux version with tar.gz extension. Also choose the right version from 32-bit (x86) and 64bit (x64) one. Change directory into one with downloaded tarball. In my case $HOME/Downloads. 1cd ~/Downloads Extract tarball. Replace with a name of dowloaded file. (just press Tab and it will be autocompleted.) 1tar -zxvf jdk- As a root create a folder in /opt where jdk will be stored. 1sudo mkdir -p /opt/java Move extracted folder to /opt/java. In my case, version number was 1.7.0_25. 1sudo mv jdk1.7.0_25 /opt/java Make JDK system default. 1sudo update-alternatives --install "/usr/bin/java" "java" "/opt/java/jdk1.7.0_25/bin/java" 1 2 3sudo update-alternatives --set java /opt/java/jdk1.7.0_25/bin/java Test installed java version. java version “1.7.0_25” Java(TM) SE Runtime Environment (build 1.7.0_25-b15) Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)
