Whenever I start a new software project I spend a good amount of time at the beginning drawing class diagrams and other flow charts to plan out how I see the application working. This part just takes a lot of thinking and testing. But at a certain point when everything is planed out I don't need to think about it so much anymore I just n...
I'm creating a project in flex builder but it's not using the flex framework, it's just pure actionscript. At the moment I have some bitmap resources embedded for drawing things, but I'd like a little animation and thought I could create swf animations for them in flash and use the [Embed()] thing to embed them in the actionscript proje...

Possible Duplicates: is else if faster than switch() case ? What is the relative performance of if/else vs. switch in Java? Ive been coding-in-the-run again....when the debugger steps through a case statement it jumps to the item that matches the conditions immediately, however when the same logic is specified using if/else ...

My site needs a chat room, and I'm also looking to implement a facebookesque person to person chat system. What is most cost-efficient/performant (purely in terms of bw and server) for me. A regular 1 second poll ajax chat, or a comet solution. Thanks. ...
Which of the following two data structures is "better"? array('key'=>array(1,2,3,4)) OR: array('key',array(1,2,3,4)) i.e., is it better to store the array as the second element in a two element array, or as the single element in an array with the key, 'key'. Assume that for my purposes, in matters of convenience, they are equivale...
Hi, I have an array with some objects, and there are several objects that are alike. E.g: fruit = [apple, orange, apple, banana, banana, orange, apple, apple] What is the most efficient way to get the most represented object from this array? In this case it would be "apple" but how would you go out and calculate that in an efficient wa...
Hi, regarding linq to objects, if i use a .Where(x => x....) and then straight afterwards use a .SkipWhile(x => x...) does this incur a performance penalty because i am going over the collection twice? Should i find a way to put everything in the Where clause or in the SkipWhile clause? ...
Using JavaScript I need to efficiently remove ~10000 keywords from a ~100000 word document, of which ~1000 will be keywords. What approach would you suggest? Would a massive regular expression be practical? Or should I just iterate through the document characters looking for keywords (boring)? Edit: Good point - only whole words, not ...
This is just a simple check to see what letter grade to output. Is there any faster and more efficient way to achieve the objective? if ( $grade >= 90 ) { echo "A"; } elseif ( $grade >= 80 ) { echo "B"; } elseif ( $grade >= 70 ) { echo "C"; } else { echo "Failed." } ...
The classic and brilliant Programming Perl reference book has a section in which the authors provide a list of advice for how to write Perl that is maximally computationally efficient, followed by a list of advice for how to write Perl that is maximally programmer efficient, followed by more advice for maintainer efficient, porter effici...

I have a complex core data mapping in my app, simplified to the relevant pats to this question here in this image: My question is how to get sorted Foo's efficiently. Let's say that in one of my views, I have a sectioned table with every foo in it. The sections are the categories. Each section of foo (in a category) has an ordering...
Hi! Suppose I have two lists, L and M. Now I want to know if they share an element. Which would be the fastest way of asking (in python) if they share an element? I don't care which elements they share, or how many, just if they share or not. For example, in this case L = [1,2,3,4,5,6] M = [8,9,10] I should get False, and here: L...
I am building a routine that processes disk buffers for forensic purposes. Am I better off using python strings or the array() type? My first thought was to use strings, but I'm trying to void unicode problems, so perhaps array('c') is better? ...
Hi, I have a standard deck of cards and then have removed a few, from the remaining cards I want to calculate all of the possible two card combinations. For example with 47 cards there is 47 choose 2 combinations. Can anyone think of an efficient way to do this other than foreach(card){ combinations.add(card, card +1) } Thanks ...
