I have an object which holds many values, and some of them (not all values from the object) need to be put in a [CSV][1] string. My approach was this:

    string csvString = o.number + &quot;,&quot; + o.id + &quot;,&quot; + o.whatever ....

Is there is a better, more elegant way?

What&#39;s the best strategy for managing third-party Python libraries with Google App Engine?

Say I want to use Flask, a webapp framework. [A blog entry](http://www.franciscosouza.com/2010/08/flying-with-flask-on-google-app-engine/) says to do this, which doesn&#39;t seem right:

    $ cd /tmp/
    $ wget http://pypi.python.org/packages/source/F/Flask/Flask-0.6.1.tar.gz
    $ tar zxf Flask-0.6.1.tar.gz
    $ cp -r Flask-0.6.1/flask ~/path/to/project/
    (... repeat for other packages ...)

There must be a better way to manage third-party code, especially if I want to track versions, test upgrades or if two libraries share a subdirectory. I know that Python can import modules from zipfiles and that _pip_ can work with a wonderful REQUIREMENTS file, and I&#39;ve seen that _pip_ has a `zip` command for use with GAE.

(Note: There&#39;s a handful of similar questions — [1], [2], [3], [4], [5] — but they&#39;re case-specific and don&#39;t really answer my question.)

I have been going through the GUI tools available for mongoDB. I got to see the mongoHub (sad that it works only on MAC OSX) ,rockMongo and some other php based tools. Is there any other tool available which is a desktop application something like the MYSQL GUI tools?

Can someone explain the difference between `MultiAutoCompleteTextView` and  `AutoCompleteTextView`?

Difference between MultiAutoCompleteTextView and AutoCompleteTextView

Me and my team are developing an application, which involves a back-end written in C++ and involves use of libraries such as OpenCV, MIL, etc.

Now, we need to develop a GUI to interface with this program, such that the GUI displays the images, and the user can interact with the images and annotate / mark the images, and then run the image processing algorithms written in C++ to display results.

For the GUI, i am stuck choosing between WPF and Qt
I personally find WPF to be easier, and more powerful than Qt
I understand that WPF is not portable to Linux, but i am not worried about this too much... 
Also, WPF uses the DirectX technology, which i may have to use to generate some 3-D visualization at a later stage.

Please help me with these points :

2. Can I interface WPF directly with C++ (and not with Visual C# ??)
3. If (Point 1) is not possible, then consider this :
   The code in C++ is going to be big, and involving some libraries too, so can i use C# to call C++ functions 
Would the time invested in learning Qt be lesser than making my unmanaged non-OO C++ code work with WPF ?

(i have a sinking feeling that I&#39;d have to write too much code for interfacing C++ with WPF, which may equal rewriting half of the actual program itself... :-( )

I have seen that standard Android UI components have a poor look and feel.

Can anyone provide me with some links or suggestions on how to improve the look and feel of an Android app?

I want to do Graphics programming in C. I had searched a lot about the compiler that provides a rich set of functions for doing GUI programming in C, but I couldn&#39;t find anything.

Basically I want to draw buttons and then accept the choice from the user and take an appropriate action. It would be helpful if you can suggest a C compiler, or a library that I can add to my compiler. I am working on the Windows operating system.

Presently, I am using TURBO C compiler that does not support direct methods for creating buttons. Any help would be appreciated.

For example, Java Swing and Android UI both use a single threaded model where a single UI thread is responsible for updating all the UI. What made the framework designers chose one thread model over the other?

Wouldn&#39;t multiple threaded UI model potentially give you more performance albeit at the cost of more complexity? I realize that the latter is a big deal because thread related bugs are *nasty* but I am wondering if there are any other advantages to single-threaded model other than simplicity?

I&#39;m trying to select a document by id

I&#39;ve tried:

    collection.update({ &quot;_id&quot;: { &quot;$oid&quot;: + theidID } }

    collection.update({ &quot;_id&quot;: theidID }

    collection.update({ &quot;_id.$oid&quot;: theidID }}

Also tried:

	collection.update({ _id: new ObjectID(theidID ) }

This gives me an error 500...

	var mongo = require(&#39;mongodb&#39;)
	var BSON = mongo.BSONPure;
	var o_id = new BSON.ObjectID(theidID );

	collection.update({ _id: o_id }


None of these work. How to select by _id?

In the MongoDB console how can I remove a record by id? Here&#39;s my collection :

    [ 
      {
         &quot;_id&quot; : { &quot;$oid&quot; : &quot;4d512b45cc9374271b02ec4f&quot; },
         &quot;name&quot; : &quot;Gazza&quot;
      },
      {
         &quot;_id&quot; : { &quot;$oid&quot; : &quot;4d513345cc9374271b02ec6c&quot; },
         &quot;name&quot; : &quot;Dave&quot;,
         &quot;adminOf&quot; : { },
         &quot;email&quot; : &quot;email@email.com&quot;
      }
    ]

And here are the commands I&#39;ve tried that don&#39;t work :

    db.test_users.remove( {&quot;_id&quot;:{&quot;$oid&quot;:new ObjectId(&quot;4d512b45cc9374271b02ec4f&quot;)}});
    db.test_users.remove( {&quot;_id&quot;:{&quot;$oid&quot;:&quot;4d513345cc9374271b02ec6c&quot;}});
    db.test_users.remove( {&quot;_id&quot;:&quot;4d512b45cc9374271b02ec4f&quot;});
    db.test_users.remove( {&quot;_id&quot;:new ObjectId(&quot;4d512b45cc9374271b02ec4f&quot;)});

Removing by name works :

    db.test_users.remove( {&quot;name&quot;:&quot;Gazza&quot;});

This is in the browser shell on at [mongodb.org][1] if that makes any difference

Thanks

Is it slow/poor form to use the `$in` operator in MongoDB with a large array of possibilities?

    posts.find({
        author : {
            $in : [&#39;friend1&#39;,&#39;friend2&#39;,&#39;friend3&#39;....&#39;friend40&#39;] 
        }
    })

App Engine, for example, won&#39;t let you use more than 30 because they translate directly to one query per item in the IN array, and so instead force you into using their method for handling [fan out][1].  While that&#39;s probably the most efficient method in Mongo too, the code for it is significantly more complex so I&#39;d prefer to just use this generic method.  

Will Mongo execute these `$in` queries efficiently for reasonable-sized datasets?

[MongoDB Suggests][1] that the easy way to handle security is to run it in a trusted environment, given that, &quot;in such a configuration, one must be sure only trusted machines can access database TCP ports.&quot;

What would be the best approach for doing this? Is there a way for mongodb to natively only listen to localhost?

I&#39;m using ubuntu 10.10

I am trying to change the type of a field from within the mongo shell.

I am doing this...

    db.meta.update(
      {&#39;fields.properties.default&#39;: { $type : 1 }}, 
      {&#39;fields.properties.default&#39;: { $type : 2 }}
    )

But it&#39;s not working!
