• How to use Javascript to popup a new window with NEARLY the same html as its parent window

  - by Ethan

  I want to create multiple versions of print-friendly pages from a single page. I am considering to do it in this way: placing several buttons on the original page and, clicking one button will popup a new window with the same html as its parent window, but with some modifications (e.g., set display attribute of some DIV's to none). It is possible to use javascript to do this?

• 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)

• How can I configure Devise for Ruby on Rails to store the emails and passwords somewhere other than in the user model?

  - by TLK

  I'd like to store emails in a separate table and allow users to save multiple emails and log in with any of them. I'd also like to store passwords in a different table. How can I configure Devise to store authentication info elsewhere? Worst case scenario, if I just have to hack into it, is there a generator to just port everything over to the app? I noticed there was a generator for the views. Thanks.

• Is it alright to call len() in a loop's conditional statement?

  - by DormoTheNord

  In C, it is considered bad practice to call strlen like this: for ( i = 0; strlen ( str ) != foo; i++ ) { // stuff } The reason, of course, is that it is inefficient since it "counts" the characters in a string multiple times. However, in Python, I see code like this quite often: for i in range ( 0, len ( list ) ): # stuff Is this bad practice? Should I store the result of len() in a variable and use that?

• When should I think about implementing my User authentication / session?

  - by Jason N

  After spending some time wireframing my ideas, I want to start building my rails app. However, I'm well aware that later down the line I'd like to consider multiple user accounts. Should I be thinking about the implementation of this from this early stage, or is this something I can implement without too much fuss later? It seems like something that would be stupid to attempt later, but part of me just wants to get the guts of the thing working - a couple of simply forms and writing/reading some stuff from the db.

• Updating a sql server table with data from another table

  - by David G

  I have two basic SQL Server tables: Customer (ID [pk], AddressLine1, AddressLine2, AddressCity, AddressDistrict, AddressPostalCode) CustomerAddress(ID [pk], CustomerID [fk], Line1, Line2, City, District, PostalCode) CustomerAddress contains multiple addresses for the Customer record. For each Customer record I want to merge the most recent CustomerAddress record where most recent is determined by the highest CustomerAddress ID value. I've currently got the following: UPDATE Customer SET AddressLine1 = CustomerAddress.Line1, AddressPostalCode = CustomerAddress.PostalCode FROM Customer, CustomerAddress WHERE Customer.ID = CustomerAddress.CustomerID which works but how can I ensure that the most recent (highest ID) CustomerAddress record is selected to update the Customer table?

  - by zeropt7

  I am new to photo apps, recently I am interested in making a sticker app like those can be seen in the appstore, I know I would need to use uiimagepickercontroller, uiscrollview and uigesturerecognizer. However I wonder which code method should I use for the app to load multiple stickers? Should it be called programmatically? Is that I would need to use the if-statement, say if one sticker is loaded, the app will auto generate a new sticker on top of it?
