雨岛屏保，好看的屏保

屏幕保护是为了保护显示器而设计的一种专门的程序。当时设计的初衷是为了防止电脑因无人操作而使显示器长时间显示同一个画面，导致老化而缩短显示器寿命。另外，虽然屏幕保护并不是专门为省电而设计的，但一般Windows下的屏幕保护程序都比较暗，大幅度降低屏幕亮度，有一定的省电作用。

优雅地下载bt.pdf

之前写了一篇使用迅雷下载冷门bt资源的帖子，由于主角是迅雷，也就没有怎么讲bt其他工具（严 格来说迅雷并不算bt下载工具），所以又不要再对bt下载工具做点补充。 理论上来说bt下载速度只跟种子健康度（源）有关，不过由于各个软件都加入了反吸血检测，所 以下载速度也有所不同（迅雷不一直都被称为吸血么？） 热门资源自不必说，要提高冷门资源下载速度，关键就两个字：开源！这里以比特彗星为例做说 明

arch linux handbook

The Arch Linux system is assembled by the user, from the shell, using basic command line tools. This is The Arch Way. Unlike the more rigid structures of other distributions and installers, there are no default environments nor configurations chosen for you. From the command line, you will add packages from the Arch repositories using the pacman tool via your internet connection and manually configure your installation by editing text files until your system is customized to your requirements. You will also manually add non- root user(s) and manage groups and permissions. This method allows for maximum flexibility, choice, and system resource control from the base up. Arch Linux is aimed at competent GNU/Linux users who desire minimal 'code separation' from their machine.
