Hungry for HD space

I am scraping the barrel to keep my HD from filling up. I have deleted most printer drivers and removed languages. I wonder if you could tell me if I can remove any of the following?
I have 2.73 GB and 4.29GB of application support folders. Some for apps I no longer use. Can I just trash these? Some are listed as 0 bytes.
I also have 1.4GB of 'packages' which look to be downloaded applications or updates as .pkg files. Can I safely delete these?
Will I miss my 494MB of apple loops (I don't use garageband except to record occasional voice podcasts)
My applications folder has a 844MB installers folder most of which is made up of 741MB of Xcode tools. Is that important?
I realise that I should buy a new computer, bigger external hard-drive etc but I need to do something while saving up.

Those in your home directory's Library/Application Support can be safely removed if you no longer use the applications. Be more careful about any in the main Library folder.
I also have 1.4GB of 'packages' which look to be downloaded applications or updates as .pkg files. Can I safely delete these?
If you mean in /Library/Packages, yes, you can delete them. It means you have chosen to "install and keep" Apple updates rather than merely installing them. If you mean in /Library/Receipts, do not delete these as Disk Utility relies on them.

Don't know - sorry.

Only if you want to install Xcode. You can always download a more up-to-date copy (which would likely be a better option anyway) or get it off your install disk.
Hope this helps,

P.S. Buying a bigger HD only helps until you fill that one up, too. Files, like mess and work, seem to expand to fill the available space. Or that could just be me.

I'm running out of hd space on my MBP with Mavericks. How do I move my Photoshop 5 app off the computer for more space. How can I store the PS5 app on DVD or on my backup hd for a future reinstall on my next Mac?

I'm running out of hd space on my MBP with Mavericks OS. How do I move my Photoshop 5 app off the computer for more space, and store the PS5 app on DVD or on my backup hd for a future reinstall on my next Mac with larger hd?
Thanks

slaglejrp,
perhaps it would be less expensive to just install a new disk with a larger capacity on your current MacBook Pro, rather than plan on buying a new Mac with a larger disk? Once your current disk has been cloned to the new disk, and the new disk has been installed into your MacBook Pro, that would allow you to keep Photoshop 5 on your current MacBook Pro.

Script for Free Space in Datafiles

Hi
Got the below script from metalink [130866.1] to identify free space within a data file.Couple of questions
1)Is dba_Free_Space an exact indicator of how much space is available in a file.
2) What is the significance of using blocks in vs using bytes.
cursor c_freespace(v_file_id in number) is
select block_id, block_id+blocks max_block
from dba_free_space
where file_id = v_file_id
order by block_id desc;
Thanks in advance for you help.

Different background for every Space?

Is there any utility that would let me specify a different background image for every Space?

That seems like a trivial feature, but it may be difficult to implement. The system would have to keep the other desktop images loaded in memory (one per space) so that switching would work seamlessly and immediately, without any delay. That's potentially 16 images. If the Mac had two displays, that's 32. And a Mac can have more displays...
To answer your question, I have not seen any utility to do that.
I think the idea for Spaces it that your desktop does not move or change. It's your open application windows that slide onto an off of your ONE desktop, based on how you have grouped them. Spaces is an extension of Exposé, which does the same type of thing with open windows. I like the way it works now, and I think it would be distracting and a bit jarring if the background also changed as the windows slid into place.

Can i reconfigure my ss hard drive for more space

can i reconfigure my ss hard drive for more space ?

I know it sounds daft but when i purchased this mac book air it said on the packaging hard drive can be "reconfigured" to double its capacity, just wondered how

Different desktop for each space.

Does anyone know of an application which will display a different desktop picture on each space when using multiple spaces?

I looked into Desktop curtain last night, after searching for an answer to this question. It seems to ALMOST work. I have a secondary monitor 1920 x 1600 px for my 15" MacBook Pro. For a given Space, Desktop Curtain puts up the same picture on both monitors, but on the larger monitor it covers only the pixel dimensions of the primary monitor. The Leopard Aurora peeks out in a nice band around the edges of the picture I want to fill the screen.
Apart from that, what I want is to be able to have a different picture on each monitor for each Space, and Desktop curtain has only the options Primary Screen or All Screens. It isn't the answer in its present form.

Can I exclude photos on my iPhone from being sent to iCloud and how? My goal is to only sync my calendar to the iCloud and exclude everything else. This way I don't have to pay for more space.

My goal is to only sync my calendar to iCloud and exclude everything else. This way I don't have to pay for more space.

Hey Murphie,
I don't pay for more space and I'm backing up two devices to iCloud, a 32G ipad and a 16G phone.
However, you can merely chose NOT to backup to iCloud. Then you won't run out of space. Items synced to iCloud do not take up your backup space.
Now, you WILL have to back up to your computer via iTunes the old fashioned way, or risk losing valuable data. Your choice.
However, if you manage your data responsibility, you won't run out of your 5G of storage on your iCloud backup from normal use.
Good luck

I'm getting different readings for free space

So I'm a little worried. I have an early 2008 MacBook Pro with a 750GB hard drive that I recently put in. I just did a system wipe and restore, and now I'm getting 2 different readings of vastly different amounts for free space. Disk Utility and About My Mac both label it at 433.29 Gigs, but Finder rates it at 590.3 Gigs! I'm fairly certain the About My Mac has the storage space correct. I have turned off mobile Time Machine backups, and I know there's a hidden partition for Recovery, but shouldn't Finder know about this? Disk Utility shows the hard drive as fine. Any other thoughts?

See if this link offer some explanations:
http://pondini.org/OSX/DiskSpace.html
You might download from the Internet OmniDiskSweeper (free) and open it. It will give you a record of all your files and the respective sizes and you can compare that to your MBP stats.
Ciao.

ACL - ILS (Item Level Security) for Webcenter Spaces

We're trying to implement Item Level Security (ILS / ACL) for Webcenter spaces. We're following the instructions from the Oracle® Fusion Middleware Administrator's Guide for Oracle WebCenter 11g Release 1 (11.1.1.5.0) http://docs.oracle.com/cd/E15586_01/webcenter.1111/e12405.pdf
After making the configuration changes, we're unable to see the "Security" option from the "File" menu in the Document explorer. Has anyone else implemented this feature and ran into similar issues?
Also, we're looking at the document properties in webcenter spaces via document explorer and do not see the "security group" or "accounts" metadata fields. We can see the "Content ID" and a whole bunch of fields and do not see "security groups" and "accounts". However, when we log into the content server and look at the folder or file "info" we can clearly see the security group and account values...not sure what is required to make these two fields show up in webcenter spaces.

Hi ,
Do you upload the documents from spaces or from UCM side ?
When you say the security and account field are not displayed , is that when viewing the content or during update ?
When the ACL features are turned off do you see the above fields ?
Thanks
Srinath

Encoding for blank spaces in url in a sql statement in report

1. What function or process do I use to encode for blank spaces in a url link in a report?
I need to link from a report to a 2nd report and pass 5 variables. I believe that I need to do that by embedding my own url in the sql for the report, since the standard report sets up for only 3 variables to be passed.
One of my variables PARTNER_FIRM has spaces in it, so how do I encode for that in the query. Currently, I have the following (... simplified).
select partner_firm,
count(distinct event) distinct_events,
'<a href="f?p=18509:4:&SESSION.::NO:4:P4_PARTNER_FIRM,P4_QUARTER,P4_CATEGORY,P4_PRODUCT_CATEGORY,P4_EVENT:' ||
partner_firm ||
'%2C&P3_QUARTER.%2C&P3_CATEGORY.%2C&P3_PRODUCT_CATEGORY.%2C&P3_EVENT.">' ||
count(distinct lower(attendee_email)) || '</a>' distinct_attendees
from all_events ...
but partner_firm has spaces which are returned. I think there is some way that I can encode for that?
Thanks,
Stephen

Sure there is:
select apex_util.url_encode('http://ww.oracle.com/') from dual

How can I buy apple watch for the space black stainless steel case and the black sport band for one order?

Unfortunately no. I asked the same question when I went to the local Apple Store for my "try on" and as of now you would have to order the watch with the metal link band and the black sports band separately.

Creating permission in UCM for WebCenter Space

Hi,
I want to automatically create a directory in UCM with permissions for the WebCenter Space users.
One WCenter Space - one directory in UCM.
In this directory will be stored files for WCenter Space.
Is it possible to configure UCM, WCenter for this case ?
Or I must resolve it programatically.
Thanks...

Hi
Requirement that you are looking for is the default behavior for Webcenter - UCM integration where in every new spaces created on WC is created a Folder on UCM .
Thanks

PS 50301 error - No Registered Index Version for Information Space

Hi there,
I'm facing an issue with the "SAP Explorer Information Space". When I try to open the Information Space, it opens fine but when its about to load, an error message appears. "It is not possible to open Information Space. Can't load the Information Space Index. (PS 50301)"
When I click "Show Details", it displays:
"No registered index version for information space"
I'm seeing this error message after updating BO 4.0 SP4 to BO 4.0 SP6.
I did try to index the information space but it fails.
So basically the question is why did this update from BO 4.0 SP4 to BO 4.0 SP6 impact the Explorer Information Space?
Environment details:
BO 4.0 SP6 on Windows 2008 Server using Oracle 10g as back-end.
Front End: using Windows 7, Mozilla Firefox, Internet explorer.
Error Message:
Explorer Indexing Error after I tried to Index this:

The way this was solved was, I created 4 new explorer services in CMC.
1- Explorer Exploration Server
2- Explorer Indexing Server
3- Explorer Master Server
4- Explorer Search Server
After creating the new ones and running them, I deleted the old ones. Then I Indexed the Information Space and everything seemed fine.

What is the keyCode for the SPACE BAR?

Greetings one and all. I am having trouble finding the
keyCode for the Space Bar, does anyone know what it is? Is there a
list somewhere for keyCodes? I have found ASCII charts but the ones
that I have found do not list space or the arrow keys.
