What is the "wheel" user and how do I get to be wheel?
I am trying to install some software that requires me to creates some directories in /usr/local, but when I try to do so it tells me that I don't have permission. So ... I looked at the directory for /usr and see that the owner of most of the directories is "wheel". Coming from my Unix background, I'd expect to see root as the owner. What is this thing called "wheel", and how can I become wheel so that I can do the things I need to do to install a new directory in there?
Roger,
I may be mistaken but by default OS X does not have a user named "wheel." However, there is an group named wheel. Depending on what flavor of unix you are using the wheel group holds the root and other system administrator accounts. In OS X the only user in the wheel group is root. All other accounts with Administrative privileges are in the "admin" group. If you need to create a directory in /usr make sure you are an administrative user (in the admin group) and precede your mkdir command with "sudo." Darwin will ask you for your login password then execute your command as if you were logged in as root. Since the root user is a part of the wheel group the directory you created will belong to the user root and the group wheel.

What is the file attribute @ and how can I get rid of it
I converted some wav files using Roxio Toast 11 and the output AIF files have a '@' in the file permissions and are not displayed in Finder. What does the '@' mean and how can I get rid of it. Would love to know why Toast adds it but I posted a question on Roxio's site and hopefully will get an answer to that.
thanks for the help
johnokay, so I yes, it does indicate extended attributes. I executed ls -l@ *.aif and got this

I then did xattr -c *.aif to clear the extended attributes which got rid of the '@' but the files are still not being displayed in Finder.

Thank you !back before IIS 6 or 7(I forgot), this ASP.NET user run ASP.NET application. If you have above IIS 6 or 7 you can simply delete this account
but first, just confirm there is no user using this account to develop ASP.NET in your environment

What's the implicit joins and how to configure it?
Hello guys
what's the implicit joins and how to configure it? What's the purpose of implicit and explicit joins?
Please help
Thank youThus, on my side, I think that :
Explicit join define the join condition between the key column from the table.
(table1.di = table2.id)
While
Implicit Join define :
* the type of join outer, inner, ...
http://gerardnico.com/wiki/dw/join/start
* And the relationship (one-to-many, cardinality)
http://gerardnico.com/wiki/dw/data_quality/relationships
And all this information are used to generate the statement (query).
And I don't really know why you have two type of key :
* Physical Foreign Keys
* Logical Foreign Keys

What does the scriptcollector do and how does it related to jsf lifecycle?
hi,
i want to know what does the scriptcollector do and how does it related to jsf lifecycle? and also in the scriptcollector if i call this,
preRender=#{myBean.onPageLoadBegin}
postRender=#{myBean.onPageLoadEnd}
how my page will react?The hx:scriptCollector is part of the IBM Faces Client Framework and has nothing to do with Sun JSF RI.
Lot of the hx components require specific Javascript and those hx components should be placed inside a single hx:scriptCollector which on its turn checks the nested hx components and renders the desired Javascript for it at the end of the tag. Check the HTML source for that Javascript. -

When I signin Apple ID showing error 403 on my mobile. What is the reason? And how can solve it?
This often means that the maximum of 3 iCloud accounts have already been created on the phone and it cannot create another account. When this happens, all you can do is re-use one of the accounts previously created or creat your account using a different iOS device or Mac, if you have one.
