每周我们都会在我们的小贴士包里与您分享一些方便的读者小贴士。本周我们将介绍一些技巧，帮助您在Linux和Windows安装之间共享文件夹，升级您的Canon固件，一种清洁键盘的简单方法。

使用符号链接协调双引导系统

Fodaro以他在双启动Windows和Fedora方面的经验写道：

I read your article on harmonizing a Windows/Ubuntu dual-boot setup before I bought a Dell laptop that I was planning to install Ubuntu on. However, when it came I discovered that it already had two other partiti*** beside the Windows one (a recovery partition, and one that displayed a license agreement), so I fit in a common partition. I thought I’d share my solution with you, in case some other Linux users find it helpful.

First, I set the Windows partition to auto-mount when I booted up, for which I used the ntfs-config package from the Software Centre.

Then I tried modifying .config/user-dirs.dirs as you showed in your article, but it didn’t work for some reason, so instead I deleted some of the folders in my home directory and replaced them with symbolic links. For example, after deleting the Documents folder (after checking that it was empty, of course), I launched terminal in my home directory and typed:

ln -sf “/media/OS/Users/Fodaro/Documents” Documents

This created a link to my Windows documents folder in place of the Documents folder in my home directory. So if a program tries to save or open a file at ~/Documents/hello.txt, it will still work, but Linux will direct it to /media/OS/Users/Fodaro/Documents/hello.txt instead. I repeated this process for some other folders in my home directory, like Pictures, Music, Videos etc., so that all of my data can be kept in one place.

感谢您用Fodaro撰写本文；我们相信其他读者也会发现自己处于类似的情况，并将从您的提示中获益。

升级佳能相机固件

比尔在信中为佳能相机用户提供了一个很好的建议：

This website has software (the Canon Hack Development Kit)for a multitude of Canon cameras that gives them features such as; RAW, Bracketing, Motion Detection to capture lightning.  Best of All its not permanent and free. It goes along well with HDR, Tilt Shift, and RAW photography.

CHDK是选择佳能相机而不是其他DSLR品牌的一个更有说服力的原因。如果你有一个佳能相机，你想挤出更多的生活/更好的功能，我们不能建议点击chdkwiki不够。一些第三方固件的功能真是太神奇了。

轻松清洁键盘

上周我们分享了一个关于你可以用来锁定键盘的软件的提示框。Leon用他的简单的无需软件解决方案写道：

You do not need to download any software to lock you keyboard for cleaning a Windows machine.  Hold down the Windows key and press the L key.  That will lock you keyboard but allow your mouse to work to unlock it.  First turn the keyboard over and jiggle it on the desk top.  Hold it up a couple of inches above the desk and drop it.  It won’t hurt the key board and will dislodge lots of tiny stuff in between the keys.  Then do your wipe down and use the mouse to turn the keyboard back on.

我们以前也用过Win+L技巧，但要预先警告的是，如果你用酒精擦拭或类似的东西用力擦拭键盘，就有可能捣碎正确的按键组合来重启电脑。不是说我们以前做过。寻找一个更深入的清洁会议？看看我们这里的导游。
