Touchscreen This page is a documentation of my dealings with various touchscreen devices I've encountered. In my experience, most modern devices work out of the box with both 10.04 LTS or 12.04 LTS, but lack the proper calibration or configuration. Some older devices, especially those embedded in laptops such as GD Itronix line of rugged computers, use serial interfaces which lack the configuration to work in Linux. The methods documented here should work with other distros as well. Global Dynamics Itronix GoBook XR-1This is a rugged laptop I picked up from ebay for a good price, which the seller wiped with Ubuntu 10.04 due to the expense of Microsoft's Windows relicensing fee. The device has an integrated serial touchscreen, and the manufacturer is notorious for hiding any and all documentation on legacy devices such as this one. With a little trial and error however, it's relatively simple to configure this and similar devices. This method should work for most G...

Rsync+sersync环境：centos 7 or centos 7.1 x64前言：一、为什么要用Rsync+sersync架构?1、sersync是基于Inotify开发的，类似于Inotify-tools的工具2、sersync可以记录下被监听目录中发生变化的（包括增加、删除、修改）具体某一个文件或某一个目录的名字，然后使用rsync同步的时候，只同步发生变化的这个文件或者这个目录。二、Rsync+Inotify-tools与Rsync+sersync这两种架构有什么区别？1、Rsync+Inotify-tools（1）：Inotify-tools只能记录下被监听的目录发生了变化（包括增加、删除、修改），并没有把具体是哪个文件或者哪个目录发生了变化记录下来；（2）：rsync在同步的时候，并不知道具体是哪个文件或者哪个目录发生了变化，每次都是对整个目录进行同步，当数据量很大时，整个目录同步非常耗时（rsync要对整个目录遍历查找对比文件），因此，效率很低。2、Rsync+sersync（1）：sersync可以记录下被监听目录中发生变化的（包括增加、删除、修改）具体某一个文件或某一个目录的名字；（2）：rsync在同步的时候，只同步发生变化的这个文件或者这个目录（每次发生变化的数据相对整个同步目录数据来说是很小的，rsync在遍历查找比对文件时，速度很快），因此，效率很...
