String concatenation vs. string substitution in Python
In Python, the where and when of using string concatenation versus string substitution eludes me. As the string concatenation has seen large boosts in performance, is this (becoming more) a stylistic decision rather than a practical one?

Hey there, I've got a block of HTML that I'm going to be using repeatedly (at various times during a users visit, not at once).

As an example HTML block... <div id='sample'> <h4>%...

Now we could add the following: ...

Best way to return the language of a given string
More specifically, I'm trying to check if given string (a sentence) is in Turkish. I can check if the string has Turkish characters such as Ç, Ş, Ü, Ö, Ğ etc. However that's not very reliable as those might be converted to C, S, U, O, G before I receive the string. Another method is to have the 100 most used words in Turkish and check...
String munging in Objective-C with NSAttributedString.
I have an NSAttributedString s and an integer i and I'd like a function that takes s and i and returns a new NSAttributedString that has a (stringified) i prepended to s.

How can I ignore accents when comparing strings in Perl?
I have this quiz application where I match what people type with the right answer. For now, what I do is basically that : if ($input =~ /$answer/i) { print "you won"; } It's nice, as if the answer is "fish" the user can type "a fish" and be counted a good answer. The problem I'm facing is that, well, my users as I are french, an...
Matching beginning of words in a NSString
Is there a method built in to NSString that tokenizes the string and searches the beginning of each token? the compare method seems to only do the beginning of a string, and using rangeOfString isn't really sufficient because it doesn't have knowledge of tokens. Right now I'm thinking the best way to do this is to call [myString comp...
