• How does Python differentiate between the different data types?

  - by wrongusername

  Sorry if this is quite noobish to you, but I'm just starting out to learn Python after learning C++ & Java, and I am wondering how in the world I could just declare variables like id = 0 and name = 'John' without any int's or string's in front! I figured out that perhaps it's because there are no ''s in a number, but how would Python figure that out in something like def increase(first, second) instead of something like int increase(int first, int second) in C++?!

• Detecting own posts on Facebook from a Chrome extension perspective

  - by Bane

  I want to create a Chrome extension that will automatically like every post I make on Facebook. My question is, how can I detect when I post something, and if that post if mine? Is there an event that occurs or something? (And just for the record, I know that these sorts of things are impossible when other apps post on my behalf, at least from an extension perspective. So I'm only concentrating on posts that I actually click the "post" button, or enter for, myself.)

• Automatically open files given as command line arguments in Python

  - by mk

  I have a lot of Perl scripts that looks something like the following. What it does is that it will automatically open any file given as a command line argument and in this case print the content of that file. If no file is given it will instead read from standard input. while ( <> ) { print $_; } Is there a way to do something similar in Python without having to explicitly open each file?

• One way Has-Many-Through

  - by Hock

  Hello, I have a Category, a Subcategory and a Product model. I have: Category has_many Subcategories Subcategory has_many Products Subcategory belongs_to Category Product belongs_to Subcategory Is there a way to have something like Category has_many Projects through Subcategories ? The 'normal' rails way wouldn't work because "subcategory" doesn't belongs to product so product does not have a subcategory_id field. Instead, I need the query to be something like SELECT * FROM products WHERE id IN category.subcategory_ids Is there a way to do that? Thanks, Nicolás Hock Isaza

Java is also ok (but flash is preferred)

• Pascal's repeat... until vs. C's do... while

  - by Bob

  In C there is a do while loop and pascal's (almost) equivalent is the repeat until loop, but there is a small difference between the two, while both structures will iterate at least once and check whether they need to do the loop again only in the end, in pascal you write the condition that need to met to terminate the loop (REPEAT UNTIL something) in C you write the condition that need to be met to continue the loop (DO WHILE something). Is there a reason why there is this difference or is it just an arbitrary decision?

  Hi, Similar to a print to pdf option, where we can choose PDF to be the output format when printing something, I am searching for something which can print to a power point file from a file. Is there any such plugin or tool? Also link to a relilable print to pdf tool would be helpful. This essentially would eliminate the export to power point option that the users are asking for. Thanks...

• MonoTouch Hello World for iPad

  - by Bryan

  I have tried following the sample Hello World for MonoTouch by creating an iPad solution. For some reason I cannot get the MainWindow to load. I followed the instructions exactly and the app just closes before even loading a view. Is there something missing? Do I need to tell the solution how to load the MainWindow.XIB or something? Please help, this seems very basic and I am about to throw MonoTouch in the garbage.
