It is a must. Period.
OK, let's tone down: it is a must for any job related to software production. Not only development.That begsl the question, What does it mean to "know" one of these systems? I would expect Product Management, Documentation, QA, and Support staff to be conversant with the fundamentals of such a tool--check in, check out, version/revision numbers--but not much more than that. Developers, on the other hand, I would generally expect "know" the system with a much higher level of expertise--query language, branching, merging, and so on.

    What is the 'other' on my iphone and how do I delete it?

    Solution
    My "other" partition was up to 25G !!!! on my iphone 4S and I didn't want to restore my phone as I would loose important SMS and info on it and re-arrnage 1000 apps again.  
    I found this link and followed the steps
    http://www.ipodrepublic.com/iphone/fixing-issue-other-files-iphone-memory/2010/0 3/31/#comment-47142
    Using that program suggested was free too.  I used it straight away after downloading it.  I removed my files in
    "media Folder".  These 3 folders was where I found the solution.
    -  Music  - all the "F" files
    - ApplicationArchives - all the big stuff
    - Recordings - all currupt M4a in there
    Vola!  My phone now has 25GB back!!!!! Other is just 26 killo bytes!  yes Killo bytes! 
    Hope that helps
    Cheers

  • I am trying to listen BBC radio news from BBC App, but on pressing the button I always get the error "there was an error playing this radio feed". What is the source of this error and how can I remove it?

    I am trying to listen BBC radio news from BBC App, but on pressing the button "live radio" I always get the error "there was an error playing this radio feed". What is the source of this error and how can I remove it?

    That is probably just a generic error message and you might not ever know what is causing it. Assuming that you have been able to play live radio with the app in the past (I know nothing about the app) and assuming that all other Internet related functions (Safari, email, etc.) are working properly on your iPad, quit the app completely and reboot your iPad.
    Go to the home screen first by tapping the home button. Double tap the home button and the recents tray will appear with all of your recent apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar.
    Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
    If that fails to resolve the issue, you might want to reboot your router, unplug it for about 30 seconds and then plug it in again.

  • What is the activity quantity in KSII and how is it arrived

    Hi,
                Could any body help me to understand what is the activity quantity in KSII. How will we arrive at the figure we get when we run KSII.
    I know the that we would be giving theplanned cost in KP06, planned activity quantity in KP26 and then when we run the price calculation in KSPI we get the total price for the cost center and the activity type. This is what is the planned total price for a period.
    I am unable to understand the differece between the planned and the standard cost. Please help me with an example.
    Standard cost is planned cost * actual hours,  correct me if I am wrong.
    Please assist,
    Regards,
    Shilpa.

    Hi Shipla ,
    You have two questions :-
    1. How to get activity quantity in KSII
    KSII is actual price calculation . Actual Price = Actual Cost/ Actual Qty..
    Actual quantty is derived from quantity confirmed in production/process order and direct activity allocation done to the cost center . If you see a Cost Center Plan/Actual variance report.. you can see the actual quantity booked in a process Order . Actual Cost is the cost booked into the cost centers ..from FI/CO /IO settlement etc ..
    During Actual costing , activity costs are generally booked at plan rate ( KP26). In KSII , actual price is computed and the difference is allocated to the cost centers.
    2. Standard cost is planned cost * actual hours
    No , plan cost is the cost you have planned for the year . You can use the plan cost to create a cost estimate . This cost estimate can be used as standard cost or for any anaylsis purpose..
    Always remeber that purpose of product cost planning is to compute product cost estimate . This estimate may be used as standard costs.
    Hope it clarifies..
    Regards

  • What is the "Other" category under storage and how can i delete items from this?

    My disc is almost full.  "About this Mac" says that I have 47 GB of "Other."  What is this Other and how can I delete items from this?

    For information about the Other category in the Storage display, see this support article.
    Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
    iPhoto ▹ Empty Trash
    Do the same in other applications, such as Aperture, that have an internal Trash feature. Then reboot. That will temporarily free up some space.
    According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of the data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.
    When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown asBackups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Reboot and it should go away.
    See this support article for some simple ways to free up storage space.
    You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore the volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.
    Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.
    Proceed further only if the problem isn't solved by the above steps.
    ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.
    Back up all data now.
    If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
    Install ODS in the Applications folder as usual. Quit it if it's running.
    Triple-click anywhere in the line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:
    sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
    Launch the built-in Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning to be careful. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
    The application window will open, eventually showing all files in all folders, sorted by size with the largest at the top. It may take a few minutes for ODS to finish scanning.
    I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.
    When you're done with ODS, quit it and also quit Terminal.

    Could be me, but your VI is not working properly on the english version of LV. Can I suggest you to try programming in English in the future?
    Yes, it's you. The VI is working just fine, except for some cosmetic issues with the labeling. I don't think is is a valid suggestion to force somebody to program in a specific language, especially since LabVIEW supports all these languages.
    Here are the problems with the VI:
    If you don't want an amplitude of zero, you need to set the amplitude control to a nonzero value before running. Simple as that!. (You could also set the input range for the amplitude control to exclude zero or use a case structure to skip certain code if the amplitude is zero).
    You could also wire the error output to an indicator so it simply displays the errors, but keeps running.
    Your while loop is currently useless. You can delete it and the program function will not change. Use a stop button at the loop condition.
    Your while loop needs some timing so it runs at a reasonable rate. Either add a small wait or configure the signal generation to "simulate acquisition timing" instead of "run as fast as possible".

  • What is the little blue bell icon and HOW do I get rid of it?

    Hi all,
    I keep getting a little blue bell icon with 2 red curved lines up at the top right corner of my screen. I do not have any alarms or alerts set. What is this and how do I get rid of it? (permanently would be nice). Thanks in advance for any wisdom y'all can impart.

    Actually neither of the above (I had said I have no alarm set).
    Turns out it is the symbol for voicemail calls I didn't receive (thank you from someone else who also has the same problem with their Pearl). To get rid of it one must go into the voicemail area and manually delete those calls.

    It is pretty short so here is the entire text:
    Symptoms
    A purplish or other colored flare, haze, or spot is imaged from out-of-scene bright light sources during still image or video capture.
    Resolution
    Most small cameras, including those in every generation of iPhone, may exhibit some form of flare at the edge of the frame when capturing an image with out-of-scene light sources. This can happen when a light source is positioned at an angle (usually just outside the field of view) so that it causes a reflection off the surfaces inside the camera module and onto the camera sensor. Moving the camera slightly to change the position at which the bright light is entering the lens, or shielding the lens with your hand, should minimize or eliminate the effect.

  • What is the "search folders" tab for and how to set it up?

    Since my scratch disk is on my external HD and my project files will be on my system drive I am wondering what location I should set the search tabs folders at.
    If anyone knows what this a tab does exactly I would like to know. I am under the impression that when the software starts up it looks in the folder that is specified under this tab to load the project.

    Search is only if it needs to find the media for a reconnect. It's not necessary to load the project. Regardless you should assign the media drive.

  • What is the "Enter Site Password" prompt and how do I make it go away?

    While using Dreamweaver (and in particular, whenever I insert an image) the following prompt appears:
    I've tried to enter all sorts of user name/password combinations, including my creative cloud login and computer account name and password.  Nothing works.  Fortunately, the pop-up goes away if I click the "Ok" or "Cancel" button, but this has started to become a nuisance.  It didn't appear for the first 2 months I used Dreamweaver, but just started appearing a couple weeks ago.
    I'm not working on any projects or sites that have password protection, or grabbing images off of FTP servers or anything like that.  I don't have any sites listed in the "Manage Sites" window.  I do work out of my inetpub/wwwroot folder, as requested by the folks at my job.
    Any help?

    Resolved the issue by setting my view to "Design" instead of "Live."
    Our client's site requires users to be logged in, and the files I was working on do call out to the client's servers/databases.  These calls (which went out every time I made a change like inserting an image) were triggering the popup.  Setting the view to "Design" instead of "Live" prevents the calls from going out.  Hope that explanation makes sense.  I only work on content for a specific portion of the site (which is massive) so most of the code was not written by me, nor do I understand it very well.
    I used TwoSuits suggestion to comment out external links to determine which one was causing the pop-up, and then commented out various .get functions inside that file to figure out the exact URL.  While this in itself didn't fix the problem, it led to a coworker remembering the trick to set the view to Design (which I had done when I first started work ~3 months ago, but a recent Dreamweaver update erased all of my settings).
    Thank you all for the replies!

  • What does the error message -203 mean and how do I fix it becaus I can't download addons nor anything else.

    The error message shows up every time I try to download an addon. Does it have to do with the update 3.6.13?

    The first thing I test to do when iMovie doesn't behave as it should is to trash the preference file.
    It's a very common way to try to solve problems with Applications that has problems.
    Reg iMovie that file is named as one or more of these
    com.apple.iMovie.plist
    com.apple.iMovie3.plist
    com.apple.iMovie7.plist
    com.apple.iMovie8.plist
    com.apple.iMovie9.plist
    com.apple.iMovieApp.plist
    Not always all of them are present - but many can be
    I also trash
    com.apple.iApps.plist
    and clean out the Cache folder
    All of them are in a folder named Library - BUT as there are more than one - most people chose the wrong one.
    The obvious one is Library on Root level - first window that opens when You open Your Start-Up Hard Disk.
    AND - that is the wrong one
    The one to find is the one in Your User Account folder - and in Mac OS X.7 and so on - it is HIDDEN.
    Easiest way to find the correct one is to go up to the top row Menu (Apple symbol to the top Left hand corner of screen) and here go to the right to GO and keep Option-key DOWN and it will Show You the correct Library.
    Now - here find the folder Preferences to move out the com.apple.xxxxxx files to the desktop WHEN APPLICATION IS NOT RUNNING ! IMPORTANT !
    then find the folder named Caches - here too - try to identify the cache files that are connected to the application - and move them too to desktop.
    Now try to run Your application e.g. iMovie
    There is an easier way to test if this is the real problem by
    • Goto Apple menu and down to System preferences
    • Select Accounts
    • Click on the Plus sign and create a new user e.g. test1
    • Apple menu - and down to Log out
    • Now log into the new user test1
    • Now see if application runs as intended
    If so - then the problem to 99% is in the Pref or Cache files.
