• In which situation is the c++/c# namespace approach better than the Java approach?

  - by mike g

  The reason I ask this is that c# could easily have copied the java convention, or a variation of it, but opted for the more flexible approach of explicitly declaring namespaces inside files. As a Java programmer often there are things that I wish I could do differently, but namespaces is not one of them. The flexbility has a certain overhead (extra braces, extra decisions for developers, making it harder to view a projects contributions to the namespace, at least without a specialist IDE). So what practical examples are there when this flexiblity is advantageous?

• Alternative for didSelectRowAtIndexPath when UITableViewCells are UIResponders?

  - by Attacus

  The cells in my tableview are horizontal UIScrollViews, which I assume is the reason didSelectRowAtIndexPath is not being called. I have my resignFirstResponder call in that method. Does anyone have an easy way for me to fix this? Is there an alternative to didSelectRowAtIndexPath? Or is there a way to get that method to fire? Thanks!

• Chrome not displaying a div

  - by Kyle Sevenoaks

  Click here to see a simple example of what I want. It's really easy, but for some reason Google won't display the "subTotalCaption2" div. It's part of a foreach loop, if needed I can add other codes. There is nothing else in the rest of the css to mess with this, I have checked about 10 times. See it live at euroworker.no/order (add items to basket) In FF and Chrome. Thanks.

• Which is better: Ad hoc queries, or stored procedures?

  - by Will

  Assuming you can't use Linq for whatever reason, is it a better practice to place your queries in stored procedures, or is it just as good a practice to execute ad hoc queries against the database (say, Sql Server for argument's sake)?

• AbsoluteTime with an integer argument behaves strangely.

  - by dreeves

  This is strange: DateList@AbsoluteTime[596523] returns {2078, 7, 2, 2, 42, 9.7849} But DateList@AbsoluteTime[596524] returns {1942, 5, 26, 20, 28, 39.5596} The question: What's going on? Note that AbsoluteTime with an integer argument is undocumented. (I think I now know what it's doing but figured this is useful to have as a StackOverflow question for future reference; and I'm curious if there's some reason for that magic 596523 number.)

• Javascript sliding (preferably jQuery)

  - by jwzk

  I am trying to think of the name of the plugin (or a plugin) that slides content in (up or down). So I have a hidden div, I click on one of the titles/header, it opens the hidden div, if I click on another header it hides the other visible div, and slides up or down the new one. I can't think of it for some reason.. anyone?

• Air applicationUpdater: updates every run, should be once a day

  - by artie

  I use the applicationUpdater framework with an Air application. The delay property is set (in AS code) to 1 day. However, the application checks every time it is run: the delay property seems to be ignored. Does any one know where last run time is stored, so I can check if there's a reason it can't seem to remember ;-) the app is at http://muchoswing.com/cantoyo

• In Perl, why do I need to @b = @{dclone(\@a)}? Why can't I just @b = dclone(\@a)?

  - by synapz

  I have an array of various things including scalars and arrays. I want to make a copy of it, and tried the following: @b = dclone(\@a) but then when I try to read one of the scalar values from b, I get nothing back. Everything appears to work when I copy it this way, though: @b = @{dclone(\@a)} What is the reason?

• Font Size Based on Char or Number Data

  - by debaucheryx

  I am trying to find a way to display numerical digits as a larger font size than chars on a website (not my idea!). The reason for this is to make the numbers stand out. I have looked for a font that would satisfy this without coding but I could not find any. Also, I don't want to slow down the website by having the font coverted to an image. Does anyone have a solution to this ridiculous problem?

• Setting the first two bytes of a block of memory as a pointer or NULL while still accessing the rest

  - by idealistikz

  Suppose I have a block of memory as such: void *block = malloc(sizeof(void *) + size); How do I set the first two bytes to a pointer or NULL while still being able to access the rest of the block of memory? For this reason, I do not want to simply assign 'block' to another pointer or NULL.

• Java ActionListener buttonPress() restriction

  - by Extinct23

  Is there a way to restrict this button to only being impressed once? The reason I ask is because for some reasons every time the button is pressed it disrupts the rest of my code. So in effort to save a massive amount of time debugging, it would be much easier to just somehow restrict the number of times it can be pressed. Thanks in advance. ActionListener pushButton = new buttonPress(); start.addActionListener(pushButton);

• Understanding Scope on Scala's For Loops (For Comprehension)

  - by T. Stone

  In Chapter 3 of Programming Scala, the author gives two examples of for loops / for comprehensions, but switches between using ()'s and {}'s. Why is this the case, as these inherently look like they're doing the same thing? Is there a reason breed <- dogBreeds is on the 2nd line in example #2? // #1 ()'s for (breed <- dogBreeds if breed.contains("Terrier"); if !breed.startsWith("Yorkshire") ) println(breed) // #2 {}'s for { breed <- dogBreeds upcasedBreed = breed.toUpperCase() } println(upcasedBreed)

• Python - How is this snippet working?

  - by orokusaki

  For some reason this function confused me: def protocol(port): return port == "443" and "https://" or "http://" Can somebody explain the order of what's happening behind the scenes to make this work the way it does. I understood it as this until I tried it: Either A) def protocol(port): if port == "443": if bool("https://"): return True elif bool("http://"): return True return False Or B) def protocol(port): if port == "443": return True + "https://" else: return True + "http://" Is this some sort of special case in Python, or am I completely misunderstanding how statements work?

• Why use <g:textField /> in Grails?

  - by knorv

  What is the reason to use g:textField in Grails if you're already familiar with standard HTML form tags? If I understand correctly the following two markup alternatives are equivalent: <input type="text" name="name" value="${params.name}" id="name" /> <g:textField name="name" value="${params.name}" /> Are there any circumstances under which using g:textField would add value? Am I missing something?
