  • Alternatives to fread and fwrite for use with structured data

    - by forest58
    The book Beginning Linux Programming (3rd ed) says "Note that fread and fwrite are not recommended for use with structured data. Part of the problem is that files written with fwrite are potentially nonportable between different machines." What does that mean exactly? What calls should I use if I want to write a portable structured data reader or writer? Direct system calls?

  • What is your laptop's display size?

    - by grigy
    I want to get a new laptop and not sure what display size is the optimal. I need it for programming while I'm traveling. So the balance is between portability and usability. My old laptop is 15.4" and I think it's big and heavy for travel.

  • If it is possible to auto-format code before and after a source control commit, checkout, diff, etc.

    - by dennisjtaylor
    If it is possible to auto-format code before and after a source control commit, checkout, diff, etc. does a company really need a standard code style? It feels like standard coding style debates that have been raging since programming began like "put the bracket on the following line" or "properly indent your (" are no longer essential. I realize in languages where white space matters the diff will have to consider it but for languages where the style is a personal preference is there really a need to worry about it anymore?

  • Clojure Box: Problem with classpath (noob question)

    - by Rainer
    Hello, I'm stuck with "Programming Clojure" on page 37 on a Windows 7 machine. After downloading the "examples" dir into "C:/clojure", I typed: user (require 'examples.introduction) and I got ; Evaluation aborted. java.io.FileNotFoundException: Could not locate examples/ introduction__init.class or examples/introduction.clj on classpath: (NO_SOURCE_FILE:0) My .emacs file looks like this: (setq swank-clojure-extra-classpaths (list "C:/Clojure")) The files in C:/Clojure are there (I triplechecked) Any help will be appreciated.

  • Programmers joy: the proccess or the result?

    - by faya
    Hello, Recently I stumbled upon this curious question: What is importing for yourself when programming: process or result? I found myself that I love outcome, when everything is done! So I tried to ask some colleagues at work, but all of them responded that they like the development process the most. Myself I like process too, but not as much as outcome. So to which people category you belong too? And if there is a reason, could you express why?

  • why is my 3n+1 problem solution wrong?

    - by nunos
    I have recently started reading "Programming Challenges" book by S. Skiena and believe or not I am kind of stuck in the very first problem. Here's a link to the problem: 3n+1 problem Here's my code: #include <iostream> #include <vector> #include <algorithm> using namespace std; unsigned long calc(unsigned long n); int main() { int i, j, a, b, m; vector<int> temp; while (true) { cin >> i >> j; if (cin.fail()) break; if (i < j) { a = i; b = j; } else { a = j; b = i; } temp.clear(); for (unsigned int k = a; k != b; k++) { temp.push_back(calc(k)); } m = *max_element(temp.begin(), temp.end()); cout << i << ' ' << j << ' ' << m << endl; } } unsigned long calc(unsigned long n) { unsigned long ret = 1; while (n != 1) { if (n % 2 == 0) n = n/2; else n = 3*n + 1; ret++; } return ret; } I know the code is inefficient and I should not be using vectors to store the data. Anyway, I still would like to know what it's wrong with this, since, for me, it makes perfect sense, even though I am getting WA (wrong answer at programming challenges judge and RE (Runtime Error) at UVa judge). Thanks.

  • unit, integration and system tests for PHP applications

    - by Sara
    Hi, We were given an assignment to develop a prototype for a customer community. It was suggested PHP as the programming language. (but we're not supposed to actually code it, just a prototype with documentation is required) I'm wondering what are the best practices/ tools used in Unit testing, Integration Testing and System testing for such a php app Thanks

  • How to extend the Eclipse Java Editor to add coloured overlays

    - by Gavin Clarke
    I have an idea for an Eclipse plugin which I've been toying with. I need to be able to extend the Eclipse Java Editor component and add coloured overlays to the code based on pluggable external metrics. Unfortunately there doesn't appear to be any kind of syntax highlighting extension point. Does anyone know how I might be able to extend the exisitng eclipse Java Editor to add custom highlighting rules? Bear in mind I'm new to Eclipse plugin programming so please give as much detail as possible.

  • Autohotkey editor

    - by Kjensen
    What is the best editor for Autohotkey with regards to syntax hightlighting, command completion (intellisense), testing etc. I am doing a bit of Autohotkey programming, and being spoiled rotten by Visual Studio, I really miss these features - especially being new to the language/framework.

  • Java MouseListener

    - by ikurtz
    I have a bunch of JLabels and i would like to trap mouse click events. at the moment i am having to use: public void mouseClicked(MouseEvent arg0) { } public void mouseExited(MouseEvent arg0) { } public void mouseEntered(MouseEvent arg0) { } public void mousePressed(MouseEvent arg0) { } public void mouseReleased(MouseEvent arg0) { System.out.println("Welcome to Java Programming!"); } I was wondering if there is a tidier way of doing this instead of having a bunch of events I do not wish trap?

  • Do console apps run faster than GUI apps?

    - by omair iqbal
    I am relatively new to world of programming. I have a few performance questions: Do console apps run faster than apps with a graphical user interface? Are languages like C and Pascal faster than object oriented languages like C++ and Delphi? I know language speed depends more on compiler than on language itself, but do compilers for procedural languages produce faster code than OO ones (including C++ compilers that can produce C code)?

  • Is there a way to avoid debugger?

    - by Gabriel Šcerbák
    I don't like debugging in a debugger, because I think it is often below the abstraction layer of the programming language and it is often not reproducible. I favor usign unit tests when possible and I think they are a good way, but it is not always that easy to implement them. Do you know about any other alternative approaches to avoid the use of debugger?

  • Have minimized windows with a unique icon/color?

    - by JB
    Are there any programs or way to get a specific icon or any icon for that matter into a minimized window? The reason why I ask is that I hate having 3 or more windows of the same program minimized on my taskbar using the same icon. When I want to open up the program i'm not sure which window to activate. -edit I'm asking for a program to do this for me, not a programming technique
