• Differences between Zend Framework 1.8 and 1.10

  - by Pat

  I want to start learning Zend Framework. My only concern is that the most recent ZF book on Amazon with good reviews teaches version 1.8 of the framework, which is now about a year old. Do you think it would be a good idea to still pick up that book or is it too old now?

• Is the following array really multidimensional?

  - by flockofcode

  Book I’ learning from claims that intArray has two dimensions. But since calling intArray.GetLength(1) will result in an IndexoutOfRange exception, couldn’t we claim that unlike rectangular arrays, intArray isn’t really multidimensional and thus has only one dimension? int[][] intArray=new int[3][]; thank you

• C Language Standard Collections Where Are They?

  - by flaxeater

  I have committed to learning C now, I'm good with Python/PHP/Bash but I've decided I'm limited by not being fluent in C. However I cannot imagine working in a language without lists and hashes, maybe I'm just jumping a gun, but surely there are 'standard' collection libraries. I do not see any in the GNU standard lib though, any suggestions?

• Determining the word width in C

  - by das_weezul

  Hi! I'm learning C right now and so I'm fiddling about with pointers. Is there a way to determine the word width of the CPU in C because I'm writing a small program which prints it's own stack (Because I'm curious how it is structured), so that information would come in handy. Right now I'm using an int pointer, as an integer is 4 Bytes wide and I'm using a 32-bit Intel Atom CPU. Thanks in advance, C gurus ;o)

• Neural Network 0 vs -1

  - by Louis

  I have seen a few times people using -1 as opposed to 0 when working with neural networks for the input data. How is this better and does it effect any of the mathematics to implement it? Edit: Using feedforward and back prop Edit 2: I gave it a go but the network stopped learning so I assume the maths would have to change somewhere?

• Divs not aligning side by side

  - by Abijah

  I've been learning about divs over the past few months, and am now able to align divs side by side. However, today I was working on my website, and my divs suddenly stopped lining up. The divs in question are: #dorsey_left, #dorsey_middle and #dorsey_right. When I remove #dorsey_left from the HTML document, #dorsey_middle and #dorsey_right align properly. I'm guessing that the problem is related to #dorsey_left, but I can't find anything in the code. This is the JsFiddle.
