Pacaur -Syu without having to type the sudo password

The Arch wiki mentions being able to run `sudo pacman -Syu` without having to type the sudo password, by running `sudo visudo` and adding something like
USER_NAME HOST_NAME=/usr/bin/pacman -Syu
However, I tend to run `pacaur -Syu` to update instead. Is it possible to add an entry to visudo to allow running this without having to type the sudo password? I'm the only user of my computer, so (I think) there are minimal security issues with this.
I've tried changing pacman to pacaur in visudo, but that did not work. (Probably because `sudo pacaur -Syu` isn't the correct command, it tells you ":: you cannot perform this operation as root". You have to run it as `pacaur -Syu`, and are then prompted for the sudo password.)

Spider.007 Perfect! That works well. Can you think of any security ramifications for allowing all of pacman instead of just -Syu? FWIW my entry is:
USER_NAME ALL=(ALL) NOPASSWD: /usr/bin/updatedb,/usr/bin/pacman
Well, allowing random packages to be installed through pacaur is already pretty bad, I don't think it'll get any worse. You could also check the pacaur source and add all specific calls it makes to pacman to the sudoers file.

How can I automatically connect to the server without having to type the password and click "connect"?

I have a Mac OS X 10.8 and a Time Capsule configurated as server with a name "Servidor" on my home. The discs are protected by Accounts, so, each person can access the server by typing own name and password. The problem is... Every time I start the computer, I see the window below:
So, every time I start I have to type my name and pass. And the box "Remember this password on my keychain" doesn't work because the "Password" is always blank when I see the window, like the image up.
Please, someone help me to automatize it so I don't need to type nothing to connect to the server. I want something that do it automatically for me.
NOTE: Please, explain clear and with details because I'm a new Mac's user.
Thank so +!

Try running KeyChain First Aid if you have not already done so.
Open Keychain Access and click on the KeyChain Access menu at upper left of the screen
Click KeyChain First Aid, then close KeyChain Access
Open System Preferences (gear icon on the dock)
Open Network
Click on AirPort or WiFi on the left
Click Advanced at the lower right
Click to highlight an old network that you no longer need, then click the - (minus) button to delete the listing
Do the same for other neworks that you no longer need
Make sure there is a check mark in the box that reads "Remember networks this computer has joined"
No other boxes should be checked.
Click OK, then click Apply
That is about all that you can do.

I recently updated to FF 9.0.1. I am on a macbook running lion. Since the update, I can no longer type just mozilla or cnn without having to type the whole address. How do I fix this?

I was able to fix this issue on the last update of FF in the console of FF. Now I am unable to find the command that allows the browser to automatically find the address I am looking for. I know it is not "Autofill". What happens is, I type just "mozilla" or "cnn" and it takes me to my isp's search. Instead of taking me to the most likely site.
Here is where it takes me - http://dnssearch.rr.com/index.php?origURL=http%3A//mozilla/&r=
Can anyone help?

That "fix" may not work completely or all the time. Road Runner has been re-directing failed DNS requests for almost 3 years now.

How do i back up my iPhone to iTunes without having to type in the password on my phone?

Basically i have a broken iPhone screen and the touch doesn't work, Therefore i cannot put in the password on my phone to allow iTunes to back it up on my Mac OR my Windows laptop so i don't loose everything on there, Is there a way to bypass this so i can back it up without having to type the password?

I have done this but it says for me to back up my iPhone I have to type the password in on my actual phone to unlock it to the homepage, I can't do that as the touch on my screen has broken, I just want to know if there is anyway I can skip that step so I can just back it up as a normal unprotected password phone.

ICal for iPhone. View all events as a list without having to type into the earth box.

iCal for iPhone. View all events as a list without having to type into the earth box.
On the previous software version I used to be able to view all my calendar events as a list by clicking on the magnifying glass. Now you have to type into the search dialog box for a list to populate. This is very frustrating and annoying because I much prefer the list format to populate everything unless I specify what I am looking for into the search box. Is there a way to view all the events as a list without having to type anything into the search box?

And you are aware of the possible options for listing the months and having an optional export value for each month.
For listing the months, you can use a number, a 3 character string, or the full name.
For the export value, the full name, the 3 character value, the 1-2 number, or the 0-11 JavaScript value.
I would look at deciding how you want to populate the drop down box and build a one page form with just this field. You can then insert that page into a PDF and copy the field as needed and then delete the inserted page. Or you could create an FDF file to create the drop down box.

How can I copy a mailing list into address book without having to type them individualy

Hi
I have a mailing list and I would like to send emails to everyone on the list in one go, I copied and pasted the list into my email, but can I have this group somewhere so that I can just call it up like an ordinary address from the address book, preferably without having to type every name individualy into the address book. I tried making a group in the address book and pasting the list in without success,if this is possible can some explain how I can acheive this
Thankyou
Richard

Richard,
Unfortunately, you have to add them one at a time - wait a sec... oh, yeah, if the contact is in your contact list it will 'auto-fill' as you begin to type. So if I want Wendy Whatshername, all I have to do is type Wen and the contacts will show up for you to select and auto-fill the name and email address.
Hope this helps,
Clinton

How do I create a contact group so that I can send an email to several contacts without having to type individual names.

How do I create a group in my contacts so I can send an email to several people without having to type names individually? In gmail on my computer I have several groups of contacts but I don't see them on my iPad air.

In the contacts app there really isn't a way to do this. What I do however, is create a note in the Notes App with the email addresses of the people I want to email to like this: [email protected]; [email protected]; [email protected]
Then when I want to email that group, I just use the copy feature of iPad, pasted it into the to line in an email and voila, I can email to a group.

Is there an easy way to switch between ehternet and wifi connection without having to disconnect the ethernet cable?

Hi All
Was wondering if there is an easy way to switch between ethernet and wifi connection on Apple TV without having to disconnect the ethernet cable. The reason I ask is that I find it quicker to use my ethernet connection via a Netgear Powerline Home Theatre Set-up to stream Trailers and Movies on the Apple TV, however this is no good when connecting directly to my Mac to stream music or TV shows in iTunes, so revert to the wifi connection that I created on my Time Capsule to do this.
Would be handy if Apple TV had a menu option where you could manually change the connection type depending on what you were doing, as per above scenario.
Cheers
Brett

Is there a way I can copy an auto signature automatically into my contacts without having to type a new contact myself?

Is there a way I can copy an auto signature from an automatically into my contacts without having to type a new contact myself?

You don't buy an unlocked phone. You buy a Verizon iPhone at full retail. I just did this myself last month. I paid full retail for the phone and activated it on my plan. This allowed me to get a new phone before I was eligible to upgrade and keep my unlimited data. I also got a good deal on trading in my iPhone 5.
You can buy the phone through Verizon or through Apple. If you buy it through Apple, I'd suggest that you not have them activated but do that yourself by logging into your account on your computer.
Best of luck.

Access schema objects without having to specify the user.

I've just created a role in a schema and assigned some priveleges.Then I created a user and granted the role to it. But as the newly created user is not the owner of the schema when I say a simle select query like this:
SELECT EMLOYEENAME FROM EMPLOYEES
I get "table or view does not exist" error. Is there a way I can wirte refer to objects in this schema without having to indicate the owner. So instead of writing SCOT.EMPLOYEES I want to write just EMPLOYEES.

Create a public synonym for the object.
CREATE PUBLIC SYNONYM EMP32 FOR SCOTT.EMP;Then you do not need to specify the schema.

This sounds more like Word than Indesign. I've never been able to resize
a column in Word without messing up the column next to it. There's
probably a way to make Word columns behave properly; I just don't know
Word that well.
In Indesign, to make table columns act the way you're describing, you
must be either dragging the column wider from the left side; or (2)
holding down the shift key while you drag. Otherwise, making a column
wider just makes the table wider.
Try dragging from the right side without the shift key. You can also
select part or all of the column, go into the Table palette, and set the
column width exactly, by numbers (which is what I usually do, because I
like to make sure that my table adds up to exactly or less than the
width of the text column).
Sometimes I need to make my tables wider than the page, temporarily,
just so I can see everything in them and decide where I can lose enough
space to fit the whole thing on the page. Remember that you can reduce
cell insets, as well.

Can I view a single page of a document, previously created in Microsoft Word, in its entirety on the screen (ipad or iphone) without having to drag the page, i.e. one page per screen?

Looking to choose an app for viewing word documents, but need to be able to view a complete page per screen (preferably full screen) without having to 'nudge' the screen 'up' to view the bottom of the page.
Will Pages do the job?

Not exactly.
You will find yourself nudging the page up or down a bit. Earlier versions of iOS Pages allowed "full page view" but that really wasn't full page either. You can squeeze the view to fit, but as soon as you release it, the document springs back to normal size - it is only about a line off from what you are looking for.
An alternative would be to view a Pages Document as a PDF and view the PDF in an app such as GoodReader - there you can see both the top and bottom edges of each page. There are many other PDF viewers available in the App Store.
Hope this helps.
