• How can I introduce a small number with a lot of significant figures into a C program?

  - by Lana

  I'm not particularly knowledgable about programming and I'm trying to figure out how to get a precise value calculated in a C program. I need a constant to the power of negative 7, with 5 significant figures. Any suggestions (keeping in mind I know very little, have never programmed in anything but c and only during required courses that I took years ago at school)? Thanks!

• Clojure example of the day?

  - by Michiel Borkent

  Is there a Clojure example of the day kind of service, like a blog, or Twitter account I can follow? Would be really nice to have a short example every day to enhance Clojure skills and to get inspired to delve deeper into the language. Clojure really lends itself well for short but powerful code.

• PHP coding - A class for each view or one class to rule them all?

  - by Kyle

  I am starting my first "programming" project in PHP making some sort of web application that give the linux program, Motion, a decent web interface. Anyways, I was curious as to how when real applications are programmed, do y'all go for a class for each view or one single class for the application altogether? I know this is more of a preference thing, I was just curious as to how it happens in real software.

• MySQLi - declaring variable after bind_param?

  - by Kerry

  This may be a completely dumb question, but I've seen a couple examples declaring the variables AFTER putting them in bind_param: http://devzone.zend.com/article/686 I've never seen this done before and all my programming knowledge says I should define them before hand. Is this a valid/preferred way?

• Must declare function prototype in C?

  - by Mohit Deshpande

  I am kind of new to C (I have prior Java, C#, and some C++ experience). In C, is it necessary to declare a function prototype or can the code compile without it? Is it good programming practice to do so? Or does it just depend on the compiler? (I am running Ubuntu 9.10 and using the GNU C Compiler, or gcc, under the Code::Blocks IDE)

• Netbeans IDE tutorials

  - by James P.

  I mostly use Eclipse but have mentionned Netbeans on my cv. Are there any good concise and up-to-date tutorials apart from the official ones that could bring me up to speed on how to use the IDE efficiently (shortcuts, debugging, views ...)? This excludes programming tutorials as I don't really need them unless there's a special manipulation involved.

• How to calculate the cycles that change one permutation into another?

  - by fortran

  Hi, I'm looking for an algorithm that given two permutations of a sequence (e.g. [2, 3, 1, 4] and [4, 1, 3, 2]) calculates the cycles that are needed to convert the first into the second (for the example, [[0, 3], [1, 2]]). The link from mathworld says that Mathematica's ToCycle function does that, but sadly I don't have any Mathematica license at hand... I'd gladly receive any pointer to an implementation of the algorithm in any FOSS language or mathematics package. Thanks!

• When to call selectRow: on a UIPickerView that has just loaded?

  - by ragnarius

  I am trying to learn iPhone/iOS programming. I have an UIPickerView that should dispay its selected row as soon as it becomes visible (it is contained on a flippSideView). Unfortunately, the flipSideViewController's awakeFromNib is not called. It is too early to call [pickView selectRow ..] from viewWillLoad (the pickView does not exist at that time), and somewhat too late to do it in viewDidAppear. So, how can I make the pickerView display the selected row as soon it becomes visible?

• What's wrong with this "if"?

  - by Gurzo

  Hello, I'm currently trying to make an AppleScript which should recognize the selected file in Finder and do the relative command in Terminal. Everything was going fine since I reached the part where it should define the language of the selected file: it just doesn't check the ifs. I checked if it writes fileExtension correctly (via return) and it does. Here is the Gist with the code, any help would be appreciated. Thanks

• I'm still learning OOP. Any tips on staying unbiased and pragmatic?

  - by marcdev

  I keep reading about defficiencies and issues with languages. Specifically, I'm learning PHP and Javascript, but I see it everywhere. This question arose while reading Javascript: The Good Parts and PHP Objects, Patterns and Practice. While understanding and avoiding easy pitfalls, is there a way I can learn the fundamentals of OOP and discover solid programming practices without overlooking important areas (or simply becoming jaded)? I'm sure I'll have plenty of opportunity to learn from mistakes!

• Reading a SquashFS archive

  - by p-static

  (SquashFS is a compressed filesystem - http://en.wikipedia.org/wiki/SquashFS) I'm looking for a way to read a SquashFS filesystem from a program. So far, I've know about the in-kernel drivers for it, but I'm sure that a userspace library for it must exist somewhere. Any language would be fine, but C is preferred. Just mounting the filesystem and using it that way is technically possible, but I'd rather avoid that route because the application I'm looking at would involve working with at least a few dozen archives at any given time.
