Best way to completely disable TopSites & Coverflow previews:

Quit Safari & unlock the “Webpage Previews” folder again.

Open Terminal (Applications/Utilities) & paste:

defaults write com.apple.Safari DebugSnapshotsUpdatePolicy -int 2

then hit return & quit Terminal.

To reactivate:

defaults delete com.apple.Safari DebugSnapshotsUpdatePolicy

不过片子已经拍了，难道就要看着大绿角忍下去么？除了祭出 PS 神器外有没有简便的方法？
我把照片放到桌面上不管，一边挠头一边闲逛，正好看到大神 Carl 在一篇 Blog 里提到可以用荧光白平衡消除绿角。

但是这个方法的缺点也很明显，选择荧光白平衡后绿角虽然不见了，但是整张照片的色彩变得怪怪的，感觉上红色略缺，颜色少了一些生动，而且这点通过色盘是无法修正的，算是美中不足吧。

原料：一个月以内收获的新葡萄。
酒精含量：随贮藏时间变化，3%到10%之间。
搭配：冷藏，喝时杯口可抹盐，建议是配Zwiebelkuchen 洋葱蛋糕，不过我一般是拿来直接喝。
地点：每年秋季，德国南部葡萄酒产区。
价格：1.79 – 1.99 欧 / 1L

注意事项：
所有的此类酒的瓶口并非密封（否则有爆瓶的危险），不要剧烈摇晃，不要倾倒放置 ── 我就不注意弄了一背包葡萄味，惨痛教训阿。
整个发酵过程持续大概一个月，喜欢甜酒的需要尽快把整瓶干掉。如果冷藏起来每两天喝一小杯可以体验一下从葡萄汁到葡萄酒的整个过程。

本地超市现在卖的白色 Federweisser 是意大利产，红色的 Roter Süsser是施瓦本本地产,。我本来想拿意大利的，被一德国大妈看到，义正辞严地教育我要支持本地农业，于是我就买了瓶这个：

老外说话比较啰嗦，解决办法直接看3b部分即可。

The solution to the everybody user being twice is easy. Run the Terminal application and for your user directory and files in it, remove the permission to outside world users.

The following command solved it for me:

chmod -R o-rwx username
chmod -R g-rwx username

This got rid of both the “unknown” user and the 2nd “everyone” user.

The reason you get this everyone problem twice, is that there are actually 2 everyones. One seems to be a “group” named everyone, and one is outside world users. Thus, you see the name everyone twice.

As for getting rid of the ACL nightmare, the following worked for me.

1. What creates the ACL problem?
You can see it in action by creating a new user account (admin access), and create some dummy files in it. Try to change the names of these files, and no problem you can do so easily. Now go to up one directory level to your user folder, open a Get Info window on the new account you just made. You will see several users in the permission section, most likely “user”, “staff”, and “everyone”.

Now use Get Info to apply a permission change to this new user account. For example, change the permission for “everyone” to Read Only. Then select “apply to enclosed items”. Now go back to your home directory and try to change the file name of items in that account, and you will find you can’t. Do a Get info on one of the files and in the permission section it says “You have custom access”, instead of “You have read and write access”.

You can also easily create the problem from the Terminal window, instead of the Get Info window. For example, go to your users folder using the Terminal application, and type the following in the terminal window.

chmod -R =rw,+X username

This will force Leopard to set the read and write permissions to the usual default to your user folder and to all files/folders recursively (this is what the -R is for) in your user folder (the +X will retain any execute permissions that are currently set). After doing this you will again create the problem.

2. What causes the problem?
Run the Terminal application (you should be in your home directory) and type:

ls -le

This will list all your files and folders in your home directory, along with the ACL extensions to the file permissions. On my machine I get under each “permission affected” files or folders the following additional information.

0: group:everyone deny delete

So this “everyone” person is not allowed to delete any files (or rename them). And this “everyone” person is a “group” that includes EVERYONE including the user as well. Thus, since “everyone” can’t change files, neither can the user. This part is confusing at first to realize what is going on since in Unix terminology normally “everyone” only refers to the outside world, and not the user himself. I believe Apple tried to use the ACL extension to prevent certain files/folder that Leopard would not want the user to rename/delete (i.e. Pictures directory), but for some reason Leopard is applying this to all files, folder, and contents of folders.

3. The solution the solution is simple. Remove this ACL condition for all files or folders in your home directory.

3a. You typically can easily do this from the user folder level in Terminal, since the affected account also has the same ACL condition applied to it. Type ls -le to see if this condition is present for the affected user folder account itself. If it is, then all you have to do is type is:

chmod -R -a# 0 username

This will remove the ACL condition (numbered 0) from the user account folder, and all files or folders in it (the -R condition causes this recursive fix of all contents of all folders).

3b. You may not be able to do this from the user folder level in Terminal if the user folder itself does not have this ACL condition. In this case, simply go to your home directory in Terminal, and fix to each file or folder within your home directory individually, and do this recursively to all contents of folders so you don’t have to do it for the contents of the folders in your home directory. Type ls -le, and find which files/folders are affected, and for each affected file/folder type the following to remove their ACL condition:

chmod -R -a# 0 file_or_folder_name

After doing this, if you type ” ls -le ” in Terminal window you will see that the ACL condition is gone from every fixed file or folder. Also, if you do a Get Info in Finder on any fixed file/folder you will see in the permission section the phrase “You can read and write”.

Should the permission problem be fixed this way by canceling the ACL conditions, I am not sure. But it is now fixed on my machine (not solved, but fixed) and I again have full access to all my files.

中外莫不如是。

Safari 5 自带的阅读器防广告效果也是一流，可惜支持这个功能的网站现在还是太少。

另外附上一个非常好用的插件：Invisible Status Bar 1.18 ，作用是模仿 Chrome 的状态栏，效果如下：

当然你得先手动关掉 Safari 本来的状态栏。
