CDO - What happened to the Couchbase IStore implementation?

Dear All,
I am looking around for possible alternative storage engines for a large cdo/emf model collection.
I spotted a bunch of commits wrt couchbase which was an engine I was considering e.g.:
/couchbase/plugins/org.eclipse.emf.cdo.tests.couchbase/src/org/eclipse/emf/cdo/tests/couchbase/AllTestsCouchbase.java
& was wondering if it ever got to a useable stage? Whether couchbase was a good platform for cdo/emf etc?
i.e. was there a reason apart from lack of time that it was never finished to the degree of making it onto the list of cdo istores?
If not then any ideas wrt how much time it would require & if so.....if it would be worth it? (i.e. if there is not some fundamental problem with it as a solution).
TIA
Adam

I vaguely remember that a "formerly active" CDO committer brought this topic up but I thought that never resulted in
working code and commits. Maybe Vik remembers...

I doubt it. Not in CDO. Maybe somewhere else?

I don't know enough about Couchbase to answer this question ;-(

As I don't know much about Couchbase I would roughly estimate something between two and six weeks. But only if it
(unlike for example MongoDB) supports proper transactions with ACID properties.

What happened to the multi-touch gestures in Finder?

I've updated to Lion last week. Overall, I think what Apple did was great to the overall experience. However, my only gripes are in Finder. What happened to the multi-touch gestures? The only thing that I can do is flip through files in cover view using two finger swipes.
What happened to the pinch to zoom in and out? I've seen other posts about this so I'll stop here. Apple please bring this function back. I'm tired of moving my mouse to the drag handle.
Secondly, I was using three finger swipes to navigate to the previous and next folder in Finder. Since two finger is used to flip through cover view, I see why they couldn't extend the back/forward function to two finger swipes as they did in Safari and I know that three finger swipe is used to change desktops. I wish that Apple was more creative to leave this function in somehow.
Is there a way to bring these functions back to Finder? These are the functions that I used all the time.

That doesn't explain why they would remove the pinch to zoom in and out. That is not be used by anything else in finder. If I'm going through pictures, I would like to zoom in on the images for cover view.
As far as the three figure swipes to go back and forth in finder, I understand why that has been removed. However, Apple could have implemented the two finger swipe just like in Safari which is sensitive to the acceleration of the swipes. If you swipe with two fingers somewhat fast, you can go back and forth between previous and next page. If you swipe with two fingers slowly, you can pan left and right on the same page.
They could have done something to retain the functionality versus taking out the functionality all together. As of now, these functionalities do not exist. I'm hoping that something is going to change and we'll have to see what the future brings.

What happens to the open item in bsid table when it is cleared

hi experts,
i have a doubt about open and cleared items of accounting documents. as we know open items of customers are stored in bsid and cleared ones in bsad. For suupose, an open item is closed ina particular period then what happened to the entry in bsid and bsad table. an entry regarding is stored in bsad (cleared),and what happens to the entry in bsid, still it will be there or removed from it.

Hi,
When ever we clear the document(Complete payment) that document will be moved to BSAD table. Other wise it will remain in BSID.
If u are making partial payment then all the partial payment documents along with original document will be stored in BSID till u made the complete payment for that invoice.
Assumption is u have to give all partial payment documents made for particular invoice item while u are making complete payment in F-28 transaction. So that these partail payment documents will also be cleared while making complete payment and moved to BSAD table.
This trasaction can be used for both partial and complete payments.
Irrespective of complete or partial payments made all the documents will remain stored in BKPF and BSEG tables.
BSID and BSAD are index tables to address performance issues with BKPF and BSEG tables.
So all open and cleared documents will be there in BKPF and BSEG tables.
All cleared documents will be there in BSAD table.
Alll open documents will be there in BSID table.
Hope it is clear.
Thanks,
Vinod.

What happens to the mail in my iMac after I delete it from my iPhone? Will it be deleted from my computer as well?

What happens to the mail in my iMac after I delete it from my iPhone? Will it be deleted from my computer as well?

If they are both using the same iCloud ID (assuming you are running your mail from iCloud), then yes, the email will disappear from your Mac after you delete it from your phone and after your phone sycs with iCloud and your Mac syncs with iCloud.
I use a windows phone, but it works the same.

Just upgraded to 5 from 3 - what happened to the page select icon? Can't find it in customize toolbars.

Used to be you could select which page you wished to go back or forward to from the arrow icons on the navigation toolbar. The history menu item only shows 10 sites without having to open history for today. What happened? Is there another icon or a new plug in for this functionality? I used it all the time.

''what happened to the page select icon (Back/Forward)''
The back/forward buttons have been moved to right-hand side of the navigation bar and the drop-down was removed. User right-click or hold click for one second to see the tab history. This is item #5 in my list.
The History menu also has "Open Previous session" and "Open closed windows",
to see more history use the History sidebar ("Ctrl+H") or the History Library List ("Ctrl+Shift+H") and sort or view by "Last visited".

E4X: What happens to the root element?

I'm working with XML using the E4X notation. I'm used to the "old school" XML APIs that use DOM and I'm a bit confused.
For example, let's consider the following XML
<mx:XML id="myXML" >
<top>
    <sub1 id="uno">
      <sub2>hello</sub2>
      <sub3>world</sub3>
    </sub1>
    <sub1 id="duo">
      <sub2>ok</sub2>
      <sub3>ko</sub3>
    </sub1>
</top>
</mx:XML>
In my code I use the following traces. This is done with the De MonsterDebugger, but all others should work the same way. I have casted the traces to String only to make it easier to ask this question (no need post images)
MonsterDebugger.trace(this, "myXML:" + myXML);
MonsterDebugger.trace(this, "myXML.sub1: " + myXML.sub1);
MonsterDebugger.trace(this, "myXML.sub1.sub2: " + myXML.sub1.sub2);
What I get as output is
(String) = myXML:<top>
<sub1 id="uno">
    <sub2>hello</sub2>
    <sub3>world</sub3>
</sub1>
<sub1 id="duo">
    <sub2>ok</sub2>
    <sub3>ko</sub3>
</sub1>
</top>
(String) = myXML.sub1: <sub1 id="uno">
<sub2>hello</sub2>
<sub3>world</sub3>
</sub1>
<sub1 id="duo">
<sub2>ok</sub2>
<sub3>ko</sub3>
</sub1>
(String) = myXML.sub1.sub2: <sub2>hello</sub2>
<sub2>ok</sub2>
All is fine above and this was a bit long abstract for my question. The question is what happens to the root element, in this case <top>? I was trying to access the data with the following notation
myXML.top.sub1; // etc
I spent quite a lot of time trying to get it to work, until I discovered that the root element is not used. Can anyone explain this?
Or, I guess the simple explanation is that the root node is ignored and the sub nodes are created as properties of the object. The question also could be stated as: Why isn't this documented in the Flex API Reference?
Thanks.
P.S. I found this article on common E4X pitfalls which also has other interesting topics when working with E4X.

What happens to the original photo after editing? Does it get replaced by the edited photo?

I just bought my first iPhone(5). On Android, when editing a photo, the original stays in your gallery and the edited photo gets placed right next to it. So what I want to know is, When editing a photo in the photo app, what happens to the original since it would be nice to be able to make different edits of it.

That is an excellent question. This is definitely not the programmed behavior of Photoshop Elements. Normally, when you edit a file, a new copy of the file is created (the original is simply left alone). This new copy of the file will have "_edited-1" added to the end of the name. It should definitely not be adding $ to the name at all.
Just as a test, create a new user account on your computer, and try editing another image to see if does the same thing there. However, I suspect there is another application on your computer that is modifying how files are saved, deleted, and renamed.

What happens to the while loop iteration counter if it runs unchecked?

I want to use the iteration counter to initialise a value on the first loop of a while statement. ie i = 0, x = 100. Fine. The application I am building will be left to run for weeks or months on end without stopping (hopefully :¬)). What happens to the iteration counter in this situation? Does it reset to 0 or what? I don't want it reinitialising any values while the loop is running other than when it starts.
I set up a while loop to try to figure out what happens and the iteration counter stops at 2147483648 which is 2^31 - 1.
Any help would be appreciated,
Thanks,
Niel.

It might be something you already looked at, but perhaps it's an option to perform the initialization outside (before) the while loop. That way it will be initialized correctly only once, no matter what the iteration counter does.
Of course if you need the counter for other purposes than initialization you might have the same problem...
Note that a lot of the timer functions also overflow after a certain time (I believe 24 or 48 days?) so be careful running very long loops (but you already knew that probably).

TS2972 I just updated all of our computers to itunes 11 and now when we try to use our home sharing, we can't import songs. What happened to the easily located "import song" feature? I wish now that I wouldn't have updated to the new itunes 11.

I recently updated all of the computers in the house to itunes 11. Now when we try to import songs from homesharing, we are unable to. What happened to the conveniently located "import song" button on the old version of itunes. Please help an old mother out please!

diesel vdub, i use 11.1.1
solved the issue today. first sync with itunes, so all the stiff you bought on the mobile will be backuped.
1. uncheck sync music in itunes and sync. all the music will be erased from mobile device
2. check music player on the mobile device. just the unwanted songs will still be there
3. go on the iphone to settings, general, usage, music player. there is just a few mb from the remaining unwanted songs. swipeleft and erase the content. switch iphone off and on again
4. repeat step 2. there will be no data. otherwise repeat step 3
5. check sync music in itunes and sync. all the music will be back again but not the unwanted songs.

Hi g,
Many features have been lost in Numbers 3. You can send feedback to Apple with Menu > Numbers > Provide Numbers Feedback.

What has been lost in Numbers 3 is here (with corrections where Apple has already reinstated some lost features in the Numbers 3.0.1 update):

I enjoy running both versions of Numbers (Numbers 2 and Numbers 3) at the same time. They each have strengths and weaknesses.
Numbers 3 did not replace your Numbers 2 (Numbers '09). Look in a folder called iWork '09 inside your Applications folder. And enjoy.

What happened to the nifty "sync" button in iTunes? It syncs as soon as I plug it in, and that's great! BUT! When I go to the iTunes Store and buy new stuff, I can't just 'sync' the device again so my new stuff gets added. Why?

Nothing happened to it.
It is still there. Maybe it says apply now, not sure, but it is still there.

"Switch to Songs view. Everything will be much clearer"
I have no use for Songs view. I always use Albums view (personal preference - I think of my library as a collection of albums, not of songs), but never had any problem at all with the use of the top-left icons in iTunes 12. Indeed, I much prefer the iTunes 12 version of the sidebar - ironically, for the reason that some seem to object to it: it doesn't clutter up a standardized listing of my library content with device-related information, and does not change if I connect an iDevice. In general, the only interaction I need at the device level is the Eject function - all content syncing is controlled through playlists associated with each device I use (which, of course, are visible and can be modified whether a device is connected or not). I only need to see the details of a device on the rare occasions I want to make a change to its behavior with respect to synchronization.

What happened to the Lightroom 5 Beta forum? Deleted, not archived or merged?

What happened to the Lightroom 5 Beta forum? I understand that LR5.2 is now in full release, but it would be nice if the Beta forum was locked and archived for reference. It seems to have been completely deleted, along with some detailed feedback by myself and other Beta testers. (I can't find it if it is archived, anyway.) None of my many, many LR5Beta forum contributions are listed in my "Content" tab in my Adobe profile. All of the links to the LR5Beta discussion in which I contributed to (such as http://forums.adobe.com/message/5271729#5271729 ) lead me to this message:
"Unauthorized

Big thumbs up for Pete.Green and Daniel T! Thank you for this incredibly fast response! I worked very hard on explaining my "Advanced Adjustment Brush" proposal back in May 2013, and I am glad that it is again available for reference... in fact, even better, as it appears that the thread is now fully unlocked and availble to reply to. I still firmly believe this proposal is the way forward for Lightroom's local adjustment tools in the future. I hope that the remainder of the LR5Beta forums will eventually be brought back for reference.
