  • python: list manipulation

    - by Jason S
    I have a list L of objects (for what it's worth this is in scons). I would like to create two lists L1 and L2 where L1 is L with an item I1 appended, and L2 is L with an item I2 appended. I would use append but that modifies the original list. How can I do this in Python? (sorry for the beginner question, I don't use the language much, just for scons)

  • Where did the name `atoi` come from?

    - by Earlz
    Ok I've been curious about this for a while. In the C language where did they come up with the name atoi for converting a string to an integer? The only thing I can think of is Array To Integer for an acronym but that doesn't really make sense.

  • Question about fwrite API

    - by michael
    Hi, In C++, there is a fwrite() which writes a buffer to a file on disk: http://www.cplusplus.com/reference/clibrary/cstdio/fwrite/ Can you please tell me if there is any buffer inside that fwrite implementation? i.e. if I call fwrite() multiple times (say 10 times), does it actually invoke file i/o 10 different times? Thank you.

  • Search and replace in apache htaccess a RewriteRule

    - by Paul Irish
    I'd basically like to get /path/file+name+with+plusses.mp3 to rewrite to /path/file name with plusses.mp3 In my case wordpress is intercepting the request and giving a 404. But the file does indeed exist. Given the constraints of the regex in mod_rewrite implementation, I haven't yet seen a straightforward way of doing this.

  • a good resource or book for architecting object-oriented software

    - by Ygam
    I have looked at a couple of books and all I have looked at were just discussing the technicalities of OOP. By technicalities I mean, here's a concept, here's some code, now get working. I have yet to see a book that discusses the architectural process, what are the ways of doing this, why doing this is bad, how to actually incorporate design patterns in a real-world project, etc. Can you recommend a good resource or book? I am mainly programming with PHP but a language-agnostic book/resource would do :)

  • Which do I select - Windows Azure or Amazon EC2 - for hosting unmanaged C++ code?

    - by sharptooth
    We have a server solution written entirely in unmanaged Visual C++. It contains complicated methods for really heavy data processing. The whole thing contains millions lines of code, so rewritning it all in some other language is not an option. We could write some extra code or make isolated changes, but rewriting everything is out of the question. Now we'd like to put it on a cloud. Which platform do we choose - Amazon EC2 or Windows Azure - and why?

  • How to use vim's syntax files in emacs to color the text

    - by Vijayender
    Are there any snippets to make emacs use the .vim syntax files found in /usr/share/vim/vimfiles/ for coloring text. Many applications like conky have the vim syntax files like "conkyrc.vim" for vim but not for emacs. So is there an easy way to use those files rather than rewriting a new language-mode for each of those available in vimfiles directory.

  • Fastest file reading in C.

    Right now I am using fread() to read a file, but in other language fread() is inefficient i'v been told. Is this the same in C? If so, how would faster file reading be done?

  • Use the right tool for the job: embedded programming

    - by EmbeddedProg
    I'm interested in programming languages well suited for embedded programming. In particular: Is it possible to program embedded systems in C++? Or is it better to use pure C? Or is C++ OK only if some features of the language (e.g. RTTI, exceptions and templates) are excluded? What about Java in this domain? Thanks.

  • Why is the Java VM so popular?

    - by sdudo
    There are more and more programming languages (Scala, Clojure,...) coming out that are made for the Java VM and are therefore compatible with the Java Byte-Code. I'm beginning to ask myself: Why the Java VM? What makes it so powerful or popular that there are new programming languages, which seem gaining popularity too, created for it? Why don't they write a new VM for a new language?

  • Displaying a list of items vertically in a table instead of horizonally

    - by MichaelMM
    I have a list of items sorted alphabetically: list = [a,b,c,d,e,f,g,h,i,j] I'm able to output the list in an html table horizonally like so: | a , b , c , d | | e , f , g , h  | | i  , j  ,    ,     | What's the algorithm to create the table vertically like this: | a , d , g , j | | b , e , h ,   | | c , f  ,  i  ,  | I'm using python, but your answer can be in any language or even pseudocode. Thanks

  • C++ Pass a hidden arg to a class constructor?

    - by JP
    I would like to define a class that accept the pointer to it's parent class as an Argument, but would it be possible to somehow pass it without needing to pass it directly such as: class Child { public: Child(Parent* hiddenArg); }; class Parent { public: Child myChild; }; I know this is weird, but I am making my own Signal/Slot implementation and Child would be a signal defined, but I would like to get the parent so I can use it's Event Dispatcher...

  • What is the use of different types of function call in js?

    - by sparrow
    I have seen different type of js function call like function aTestFunction(param) { // function body } and also: aTestFunction = function(param) { // function body } what is the difference in above to implementaion? Also, i found that jquery/prototype js framework uses the second implementation in most cases. Is there any special reason for that? Sorry, I am a novice so this question may be silly to someone but will be helpful me if any guru out there helps me with this silly question. Thanks in advance.

  • How to pass a function as an argument?

    - by TFerrell
    I'm looking to pass an anonymous function to another function, but it doesn't seem to be working as I'd like. I've attached the code, I think it'd give you a better idea what I'd to do. <script language="javascript" type="text/javascript"> function do_work(success) { success; } do_work(function () { alert("hello") }); </script> Thanks in advance for any help.
