• UITabBarController not showing all view controllers

  - by rounak

  My UITabBarcontroller has two view controllers -Favorites -Keypad I add these two controllers in an array in the order Favorites,Keypad,nil.

• Usability of an endless/infinite scroll

  - by Anton Gogolev

  What are pros and cons of this technique (see Softfolio for an example). Two things I personally thought of are as follows: Impossible to tell someone where an item of interest is located (like, you probably won't say "324-th row, second column") Broken navigation when you return back to an infinitely scrolled page. What else can you think of? And what do you personally think of this approach in general. Would you use this in you projects?

  Say I have one class ClassBig with 100 methods inside, and a second with only 10 methods ClassSmall When I have objects at runtime ClassBig big = new ClassBig(); ClassSmall small = new ClassSmall(); Does the larger class take up more memory space? If both classes contained an identical method, does the larger class take longer to execute it?

• iPhone - Track three touches

  - by Striker

  Suppose you have three points of contact on the iPhone screen and one of those touches moves... The touchesMoved method will be invoked and the [[event touchesForView:self] count] will be equal to '3' because there are three touches for the event, but how can you distinguish between the touches? For example - find out whether it was the first, second, or third touch which moved? Thanks.

  it is quite strange that the following works: - 1.upto(30) do |i| = i %br but the following won't: %div this line - 1.upto(30) do |i| = i %br Isn't the second part just to add a div and let the numbers go into that div?

• MS SQL 2005: Why would a delete from a temp table hang forever?

  - by Dr. Zim

  DELETE FROM #tItem_ID WHERE #tItem_ID.Item_ID NOT IN ( SELECT DISTINCT Item_ID FROM Item_Keyword JOIN Keyword ON Item_Keyword.Keyword_ID = Keyword.Record_ID WHERE Keyword LIKE @tmpKW) The Keyword is %macaroni%. Both temp tables are 3300 items long. The inner select executes in under a second. All strings are nvarchar(249). All IDs are int. Any ideas? I executed it (it's in a stored proc) for over 12 minutes without it finishing.

• DateTime Formatting in repeater

  - by Krishna

  Hi, I am trying to format the date time (yyyy/MM/dd) in a repeater which is binded to an ObjectDataSource as shown (THIS WORKS) <%# ((MyType)Container.DataItem).CreateDateTime.ToString("yyyy/MM/dd")% (THIS DOES`NT WORKS) <%# String.Format("{0:yyyy/MM/dd}",((MyType)Container.DataItem).UpdateDateTime)% I want to have both things working because sometimes the property UpdateDateTime is null, in such cases the second line of code handles smart.

• Play an AudioBufferSourceNode twice?

  - by alltom

  Should I be able to use the same AudioBufferSourceNode to play a sound multiple times? For some reason, calling noteGrainOn a second time doesn't play audio, even with an intervening noteOff. This code only plays the sound once: var node = audioContext.createBufferSource() node.buffer = audioBuffer node.connect(audioContext.destination) var now = audioContext.currentTime node.noteGrainOn(now, 0, 2) node.noteOff(now + 2) node.noteGrainOn(now + 3, 0, 2) node.noteOff(now + 5)

• stm monad problem

  - by Alex

  This is just a hypothetical scenario to illustrate my question. Suppose that there are two threads and one TVar shared between them. In one thread there is an atomically block that reads the TVar and takes 10s to complete. In another thread is an atomically block that modifies the TVar every second. Will the first atomically block ever complete? Surely it will just keep going back to the beginning, because the log is in an inconsistent state?
