How it works ???

hi,
public int ctpop(int i) {
int iRet = 0;
for(;i > 0; i >>= 1) {
iRet += i&1;
return iRet;
how it works ??
; > ???
what is this ???
thankx,

public int ctpop(int i) {
int iRet = 0;
for(;i > 0; i >>= 1) {
iRet += i&1;
return iRet;
}It's a for loop with an empty initialization part. BTW,
change the i>>=1 part to i>>>=1, otherwise this
bit counting function fails to work for values i < 0.
kind regards,

  • How to work with both desktop and Surface pro 3

    Hello,
    I have a desktop for my normal use of Adobe Creative Cloud for Photoshop and Lightroom.  I have my lightroom catalog on a separate external drive.  I just got Surface pro 3 to do Adobe on it.  I am now confused on how to work on Surface and how to access my Lightroom catalog.
    Thanks for your help.

    Just install Lightroom on your Surface Pro, plug-in the external drive, and double-click the LR catalog file.

  • How to work with 360 video?

    I am new to AE and am trying to work with a 360 equirectangular video I shot with a Freedom 360 and 6 go pros.
    Are there any tutorials on how to work with 360 spherical videos? Do I need to download additional plugins?
    Thank you,
    Phil

    Phil,
    Of course, the image needs to be big for this, but the plugin you would use is CC Sphere.
    Drop your movie into a composition and apply CC Sphere to the video.
    Then set the Render option in the effect to "Inside".
    Under Shading set Ambient to 100% and Diffuse to 0%.
    Then scale inside the effect until the image fills the screen.
    Then you'll be able to use the Rotate Y controls in CC Sphere to spin around inside your video!
    You can also add Optics Compensation and Reverse the Lens Distortion to straighten out your image.
    Let me know if you have any questions!

  • Hey Guys, from Germany. I want to connect my iMac 21" with my Tv just for fun. Does anyone know, how it works. With a Hdmi adapter?

    Hey guys! I want to connect my Imac 21 " with my Tv just for fun. Does anyone know , how it works?

    Selecting the correct adapter and cable depends on which year model iMac you have and what inputs the TV has?
    Check the User's Guide that came with your iMac or your Spec's at > Apple - Support - Technical Specifications
    to see if your iMac has a Mini-DVI or Mini DisplayPort and then select that adapter with the correct connection for the TV.
    Example: if you have a 2010 or 2011 iMac and an HDMI ready TV, then you would want the > Moshi Mini DP to HDMI Adapter with Audio Support - Apple Store (U.S.)

  • I was looking at the "Find my iPhone" app and I have a doubt regarding how it works for the macbook. In order to detect the location, the macbook should remain signed into iCloud. What if the thief logs out of iCloud. Would we able to locate the macbook?

    I was looking at the "Find my iPhone" app and I have a doubt regarding how it works for the macbook. In order to detect the location, the macbook should remain signed into iCloud. What if the person who has stolen my macbook logs out of iCloud.
    It should work fine for iPhone/iPad because we can enable "Restrictions" to prevent the user from signing out of iCloud. Do we have simialr settings for the macbook?
    Thanks,

    If it's not on the device list, it indicates that someone has gone to Find My iPhone on icloud.com and manually deleted it from the device list (as explained here: http://help.apple.com/icloud/#mmfc0eeddd), and it has not gone back online since (which would cause it to reappear on the device list; Find My iPhone has been turned of in settings on the device; the iClolud account has been deleted from the device; or the entire devices has been erased and restored.
    Unfortunately, there's no other way to track the phone other than through Find My iPhone.  You could call your carrier and see if they would blackliste it so at least the theif couldn't use it.

  • I need to change my apple ID because I'm changing my email address. I'm worried that when I do, I'll no longer be able to use my first generation apple tv unless I change the apple ID there as well.  Does anyone know how this works??

    I have to change my apple ID because I'm changing my email address. (I have a Comcast address and am switching to U-verse) I'm worried that when I do, I'll no longer be able to use my first generation apple tv unless I change the apple ID there as well. I'm also trying to find out if changing my apple ID is going to interfere with getting my itunes content on my computer and my iphone.  Does anyone know how this works??

    My iTunes appleID is an old defunct e-mail address - it does not have to be functional.
    Do what Winston says to ensure you keep getting correspondence related to that ID.

  • I pad 2 updated to iOS 6.1.3 and now wifi is greyed out. Apple support engineers say replace but my warranty exited 09/12. Funny how it worked perfectly fine before the update.

    I just updated to6.1.3 and now my wifi button is greyed out. Apple support said it is a hardware issue. Funny how it worked just fine on the previous iOS. Now apple wants me to buy a replace not because my warranty expired 09/12. Seems to me like ios6.1.3 was an update to sell more products. Tried all suggested fixes with no success. With all the noted issues with ios6 there may be another class action lawsuit coming. Apple tech senior advisor unwilling to help. First advisor told me just buy a new I pad. Second advisor wants me to pay for a replacement. Can someone explain to me how an apple approved software upgrade that damaged my i pad is classified as my fault. I've seen some shady selling techniques but this one takes the cake in my book. Anyone have the contact information to higher up executives in apple for me to speak with about my issues?

    Have you check the following?
    Verify that airplane mode is off by tapping Settings > Airplane Mode.
    Reset the network settings by tapping Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings
    Ensure that your device is using the latest software.
    If your issue is still unresolved, perform a software restore in iTune

  • How IE works for  flat file

    Hi all:
         As we all know that, when IE gets a idoc's service name from SLD, then use it with idoc's message type and Idoc type to do receiver determniation, what about flat file ? how can we know its Service name and interface name  if there is only a flat file on FTP?  how IE works for Flat file ?
         Couldn't thank you more

    Hi,
    For any idoc scenarious, you would use business systems rather than business service which is stored in SLD. So the IE would fetch it from SLD at runtime.
    For file based scenarious also, you can create business system as type third party and use the same.
    Is that answer your question?

  • Better process for introducing new features and explaining how they work

    There are all kinds of new features being added to the Creative Cloud app but knowing what they are and learning about how they work isn't the most user friendly process. The current process is read the release notes after updating to a new version. The release notes should hyperlink to the related features in the product help. It would be great if there was a "What's New" section for the Creative Cloud app itself with new releases which included an introduction to new features just like there is for the desktop products.

    This is a poorly explained reason about why is so important having a loupe in Photoshop. I've not also, used the best example, but I will. This belongs to the ADDITIONAL FEATURES: Loupe/Magnificator View:. Also, I will try to make my english clrearer, but here it goes:

  • How does works default parameters in a program with logical database PNP?

    Hi Friends,
      I have a basic program, i need to filter info with period parameters in a program that uses logical database PNP, but it doesn't work.
      If i use "person selection period" that it's suposed to filter info according to infotype 0001 (as the sap help says), it doesn't work, i use: PNPBEGPS = today and PNPENDPS = today, and the result it's a lot of registers that doesn't meet that criteria.
      Also i tried with: data selection period, today, up to day, current month. And the result it's with the same problem.
      How does works period parameters in a program with logical database PNP?
    This it's the program example, i use the default category.
    REPORT  ZRPHRTEST.
    tables: pernr.
    infotypes: 0001.
    start-of-selection.
    get pernr.
      write: pernr-pernr, p0001-begda, p0001-endda.
    end-of-selection.
    write 'fin'.

    Hi,
    Define pernr table under tables statement then and use GET PERNR event.This get event is followed by End-Of-Selection.
    Syntax: Tables pernr.
                Get pernr.
    Try, activate and test. This should solve your problem.

    Following are the steps involved in general :
    1. Select the filter Worklist and enter your name in the input field of the object list selection. Press the enter key. Your object list is displayed.
    2. Place your cursor on the highest node(PROJECT BY XXXXXX). Select Create project from the context menu by right-clicking on it. You see the dialog box Create project.
    3. Enter a project name, description, packages, and namespaces for each system used. Leave the dialog box by pressing the enter key.
    Specify transport requests. The Project is created and appears in the object list.
    4. Place your cursor on the new project in the object list and select Create extension in the context menu. You see the dialog box Create extension.
    5. Enter a name and description. Define a Business Object and extension type. Press the enter key.The extension is created and appears in the object list below the project.
    6. Place your cursor on the new extension in the object list and select Call wizard in the context menu. The wizard for the extension action starts automatically.
    7. Fill in the input fields following the notes on screen and end the wizard by clicking on Complete.The extension tasks have been created and appear in the object list.
    Project and extension are created !
    Also take care that you have the Transport Requests and Save the Project and Extensions against a Development Class !
    In general , EEW will automatically puts the fields on the Screen. We donot want to worry abt that !
    The generated BADIs can be implemented to do some Checks(for example) !
    I hope this helps !
    Thanks

  • How much work is it to add a callout item to open document in a specified program

    Hi, I am hoping someone can point me in the right direction.
    I want to know how much work it is to get a Sharepoint developer to add a link to the callout above, e.g. at the top level near OPEN SHARE, or in the sub menu would also be fine. The link would open the selected document in our application which can open
    TIFF / PDF and other image files. The link could say "Edit this document in MyApp", or "View this document in MyApp" as examples. We would need to provide this in a modular way, so that customers could optionally deploy it to their own
    sharepoint site. A possibility, if the customization is not a big job would be to write a document with details on how to customize the Sharepoint site to achieve this. I'm not sure if Sharepoint has a more intuitive way of sharing this type of customization,
    e.g. as an App package.
    Any idea how much work is involved approximately in developer hours?
    And is there any terminology I could have described better above?
    My apologies, I don't have any experience with Sharepoint but we have a requirement to integrate our software with it.
    This link https://msdn.microsoft.com/en-us/library/dn135236.aspx has some good info, which I think is in the right direction. But for myself with no Sharepoint experience is a bit above my head.
    Any advice is appreciated. Depending how much work it is I may post this up as a freelance job. (basically need to get approval for a budget, and ensure the scope is defined etc.)

    Hi,
    If you want to add the custom action in sub menu, we can use SharePoint designer to achieve it.
    Open SharePoint designer -> Find Lists and Libraries -> Documents
    More information:
    http://sharepoint-community.net/profiles/blogs/sharepoint-designer-custom-actions
    If you want to achieve the requirement of "The link would open the selected document in our application which can open TIFF / PDF and other image files". I suggest you use some jQuery plugin to achieve it.

  • Foreign Currency Translation at Year End - How SAP Works for P&L items?

    Hi All,
    I wanted to know "How SAP works on Foreign Currency Translation at year end" from Local Currency to Group Currency for P&L Items.
    I know how SAP works for Balance sheet items but am really confused with when the translation was done for P&L Items.
    Configuration:
    We are on ECC 6.0 . Local Currency is CAD and we have 2nd Local Currency as "USD - Group Curr".
    We have set up Valuation Method - 4
    We have set up Valuation Area - 40
    For Account Determination for Currency Translation, GL accounts (Loss, Gain and B/S Adj)  were setup for the combination of Chart of Accounts, Val Area and Fin Stmt Ver.
    Sales Account Balance
    CAD (LC)        USD (2nd LC)       
    1000                   920                        
    Using tcode "FAGL_FC_TRANS", we translated our P&L items.
    Local Currency is CAD and Group Currency is USD.
    CAD 1000 and USD 920 are cumulative balances over a period of time.
    Since at the end of year CAD became stronger, exchange rate is 1.11 as an example
    Sales Account Balance
    CAD (LC)        USD (2nd LC)        Translated Value in USD
    1000                   920                        900
    System passed the following entry in USD:
    Debit Balance Sheet Adj A/c 20
    Credit Translation Gain / Loss A/c 20
    Here are the questions:
    1. How does over all translation work? - Should we get any Gain / Loss and have an effect on P&L when all accounts (P&L, B/S) are translated?
    2. How can there be a gain entry when USD value has really fallen from 920 to 900 in the current case.
    Thanks for your time.
    Vijay

    Hi,
    I had this issue too.  The entry was just opposite to what it should be.  I just flipped the accounts in table FAGL_T030TR.
    Example: 410000 is sales account which normally should have a credit balance.  Here are some entries that were posted to sales in 03/2009 and I am running FAGL_FC_TRANS at the end of the month.
    March 1, 2009 Cr. Sales CAD 1000- USD 900-
    March 2, 2009 Cr. Sales CAD  500- USD 480-
    During FC translation transaction, system takes the balance in the account for the period (if you execute it with 'Val. period balance only' checkbox checked) and not the cumulative balance.  SAP recommends translating period balance only (and not cumulative balance) for P&L accounts.  It sees a balance in LC (this again depends on the config. you have in OB22 - whether the indicator is 1 (TC as source currency) or 2 (LC as source currency for translation)) which is 1500, converts that at month end rate.  After conversion, lets say the balance is 1400-.
    In this case, we expect a credit entry on sales account
    March 31, 2009 Cr. Sales CAD 0  USD 20-
    But system was just posting the opposite.  I then flipped the accounts in FC translation configuration.  I know it is misleading.  In that configuration, system says balance sheet adjustment account, but what you should actually give there is your gain/loss account.  Our gain/loss a/c. falls in the same GL account range as the main account.  For example, for 410000, it is 410999 and for 510000, it is 510999.  We report accounts 410000 to 410999 in the same node in the FSV.
    Pl. feel free to ask further questions about this.  Pl. test in your system and correct me if my above reply is wrong.
    Cheers!
