Downsides of changing owner name, Long and short?

I have a bunch of Macs and I am thinking of changing their names both the "official" long name and the nickname (short) name. With Leopard it is now possible to change not only the short name but also the home directory and even user and group ids (501, etc)
I know that TM will most likely create a new backup since it is based on the computer name.
Other than that, what can I expect to happen?
Basically, when I got my new MBP I did the Setup Assistant thing, so two computers had the same name.
Later when I networked them, one was changed to Same Name (2) which is fine. And nothing happened.
But these two boxes still have the same short name.
Again, if I change one to a different short name, what happens? Boom! or simply BSD takes care of the various ownerships and such and it becomes a transparent change?

If you change the computer's name in the Sharing pane of System Preferences, no ownership issues will occur, as this isn't part of the account database. Changing the short or long names themselves won't affect ownership, which is based on the numeric UID instead of the name.

Thanks, Niel.
That UID you refer to, is that that very long number UUID? Or is that something else again?
Actually I think I can leave the short name the same and only change the sharing name, which is what is seen on the network.
Lastly, I hope, what if I were to change the User Name in the User Preferences? I know that the default sharing name is based on this by adding an " 's " and the word Computer.
On the other hand, perhaps the main User Name is not important for what I want to do which is primarily to have unique names on the network rather than the ugly "X Y's Computer (2)" which is what happened the first time I connected them
With TM, I trust that anything I do that is not a good thing can be remedied by using the Wayback Machine.

Equivalent rect long and short sides

Not so sure if anybody else already came across this problem or not. Any suggestion is welcome.
I have a simple isolated object to be fitted into an ideal rectangle which will then be used for a metrology purpose in following step. I was trying to make use of the equivalent rect long and shot sides from particle analysis operation, but it seems the particle analysis always gives a same value to the long side and short side. Attached picture shows the calculation results from vision assistant. I tried to calculate the equivalent rect sides from the given area and perimeter. The results tends to become complex values as the perimeter seems smaller than it should be(i.e.. P^2 smaller than 16*A). It may be one reason to produce same value to equivalent rect long and short side.
PS: the expression for calculation of equivalent rect long and short side in the page: http://zone.ni.com/reference/en-XX/help/372916L-01/nivisionconcepts/particle_measurements/ seems not right. It should be (P-sqrt(P^2-16A))/4, rather than P/4-sqrt(P^2-16A).

Hi paris_sun,
I am assuming you are using the latest version of Vision Assistant 2011 SP1.
I would just like to clarify what you are trying to achieve. This is to measure the long and short (length and width) side of a rectangular shape in your image by using:
Processing Functions: Binary >> Particle analysis
Something I could suggest is to play around with a more definative rectangle and see if this helps. I have tried using a rectangle and the measurements have come out fine.
The shape you are measuring happens to have the same size dimensions i.e. a square.
Where are you acquiring your image from? And are you expecting it to be a square?
With regards to the formulas being incorrect I will look into this for you.

HT1212 How do I change owner name and profile to iPad I just traded up for a new iPad Air?

I just bought a new iPad Air and wish to give my old iPad 2 to my brother. How do I delete my owner profile and appropriate data, and reset the old iPad to his owner name & profile?

If it's registered to your account then you can log into your account and remove it : https://supportprofile.apple.com/ - your brother can then register it to his account.
For the content that's on the iPad (you've copied off everything that you want ?) then you can log out of your account by by tapping on your id in Settings > iTunes & App Store, remove your iCloud account from it (Settings > iCloud > Sign Out) and remove all of your content and put it back to factory defaults via Settings > General > Reset > Erase All Content And Settings. Your brother should then be able to set it up with his account and put his own content on it.

Changing Owner Name On CSS

Is there a way to change an owner name, short of creating a new one and re creating all the rules defined under the old name in the new one?

You will need to create a new owner and move all of the rules.

Why is my website name long and repeating?

heres my website name www.dallaskruse.com
when it comes up in the URL, its dallaskruse.com/DallasKruse.com/dallaskruse.com.html
why so long?

why so long?
Because you named it that way. If you want it shorter, change your Site name inside iWeb to dk or something instead of DallasKruse.com, and change the name of your top page to Home or Welcome instead of dallaskruse.com.
Also what comes up in the address bar of the browser is not of any importance. Your url that you give out to people is always just

Change owners name

I have a used iMac 24 - and the previous owners name keeps on coming up. Can I change this? Thanks

try this: adapt ... How-To: Changing home folder name/account name in Leopard
When users create an account on their systems, the home folder is named with the "short" username; changing it, or the login name is not straightforward. In previous versions of Mac OS X, the easiest way to change the short name was usually to create a new account and transfer files to it. For Leopard users, however, the procedure is relatively simple:
1. Enable the root user and log in as root. This can be done by opening "Directory Utility", clicking the lock and authenticating, and then choosing "Enable Root User" from the "Edit" menu. After supplying a password for this account, users can log out and log back in as "root".
2. Locate the home folder to be changed, and rename it accordingly, ensuring the name is lowercase, letters only, and all one word.
3. Go to the "Accounts" system preferences and create a new user, giving that user a "short" name that's the same as the new home folder name. The system will ask if the present home folder is to be used, and users should click "ok". Then ensure the new user can administer the computer (if the user is to be an administrator).
4. Log out of the system and log back in as the new user, and if everything behaves normally, users can then delete the old user in the "System Preferences".
5. Reverse the steps to enable the "root" user in order to deactivate it. The root user account should only be enabled temporarily for running certain administrative tasks such as this.

Settings > General > Reset > Erase All Contents And Settings should put the iPad back to factory settings, and you should then be able to associate your account id with it (Settings > Store) and you can give it a new name when connected to iTunes on your computer (http://support.apple.com/kb/HT3965)

How to change owner of queries and transport.

Hi Experts,
Earlier the queries are designed by some other user.According to business requirements I have customised the data targets and infosets also accordingly.All queries are designed on infosets only.
If I am coming to query designer to change queries according to requirements, i am not getting change or edit mode for that,even if I saved the query with some other technical name also I am not getting change or edit mode.
While I open the opened the query it is showing the following errors :
1. Bex transport request is not available or not suitable.
2. Choose an existing request.
Up to my understanding to assign the queries to my own BEX transport requests ,how can I change the previous query owner to my user name.
If I assign to own bex transport request then
Please let me know if any information needed still.

Dear,
As explained above .....go to SE09 and selct the request and change the owner...
Also,
If u use SAVE AS option for the existing query,,,then a new query opens..
and assign that query to a NEW Transport Request...
This solves ur problem...
The problem of
1. Bex transport request is not available or not suitable.
2. Choose an existing request.
is because... the query has been attached to a TR which has been already moved to Quality or Prod...
So any changes have to be put in that request which is no longer available..
So use Save AS option and assign it to a new TR.
Hope this helps u..
Best Regards,
VVenkat..

Change domain name clients and server

Hello,
I want to change the domain name from eg ".vancouver.gov" to ".vancouver.local" on all of our devices in the network. Zcm has been installed with ".vancouver.gov" and the clients also are registered with ".vancouver.gov". When i change the domain name on the workstations and change the corresponding dns entries of the workstations to ".vancouver.gov" i cannot register workstations anymore and wol does not work anymore. Distributing applications to the workstation does work.
Anybody now how to accomplish this change.
We have about 400 workstations and 1 zcm 10.3.3 server.
Thanks.
Ren

I would recommend an SR.
Changing the DNS of Devices should not impact any of that, so long as
the clients can still properly resolve the servers and you are not
destroying the old DNS zone.
This may indicate that the CA/Server CERTs do not have the fullied
qualified DNS name of the server but perhaps just the short name.
Also, I would not recommend attempting to fix any certs right away, but
rather using the "Additional DNS Name" setting on your server, since
changing a Cert could cause lots for work on client PCs.
Later versions of ZCM make changing server certs a little easier but for
10.3.3, I would just use the server setting instead of a change.
But since I suspect you can create an SR as most government accounts
can, it may be simplest to go that route but keep my thoughts avoiding
any cert rebuilds in mind if there is any issue with the names in the
server cert.
