  • [boost::filesystem] performance: is it better to read all files once, or use b::fs functions over an

    - by rubenvb
    I'm conflicted between a "read once, use memory+pointers to files" and a "read when necessary" approach. The latter is of course much easier (no additional classes needed to store the whole dir structure), but IMO it is slower? A little clarification: I'm writing a simple build system, that read a project file, checks if all files are present, and runs some compile steps. The file tree is static, so the first option doesn't need to be very dynamic and only needs to be built once every time the program is run. Thanks

  • Features to remove from C++

    - by Justin Ethier
    This question was inspired by What features would you like to see added to C++? (also see What features do you miss in C++?). C++ is a great general-purpose language, but perhaps too general and feature-rich: multiple inheritance, operator overloading, manual memory management, templates, smart pointers, virtual destructors, legacy frameworks (think MFC), and I could go on. Is there any one feature or aspect of C++ that you would like removed to make our lives easier as C++ developers? One feature per answer, please.

    - by Jack Null

  • Repeat elements of vector in R

    - by bshor
    Hi, I'm trying to repeat the elements of vector a, b number of times. That is, a="abc" should be "aabbcc" if y = 2. Why doesn't either of the following code examples work? sapply(a, function (x) rep(x,b)) and from the plyr package, aaply(a, function (x) rep(x,b)) I know I'm missing something very obvious ...

  • What good programming practices will change with C++0x?

    - by Jon
    For example, "Don't return objects by value if they are expensive to copy" (RVO can't always be used). This advice might change because of rvalue references. The same might be said about storing collections of pointers to objects, because copying them by value into the collection was too expensive; this reason might no longer be valid. Or the use of enums might be discouraged in favour of "enum class". What other practices or tips will change?

    - by nick
    The following code works: $(".valClear").each(function () { if ($(this).val().indexOf(".png") == -1) { $(this).val(''); } }); However this doesn't (the value is removed even if it contains .png or .jpeg), what am I doing wrong? $(".valClear").each(function () { if (($(this).val().indexOf(".png") == -1) || ($(this).val().indexOf(".jpeg") == -1)) { $(this).val(''); } });

  • How can I get the correct headers automatically given a filetype in PHP?

    - by incrediman
    A few times I've run into situations where I'd like to be able to include a file using PHP, and depending on the included filetype, output the appropriate headers. In the past I've just done this manually by switch/casing the extension type with the appropriate content-type headers. However what I'm wondering now is if there's a function like get_header($filename) or maybe get_contenttype($extension) For example if I wanted to route all requests for media through a php file, I could use that function to output the correct headers.

  • C++: Chr() and unichr() equivalent?

    - by alex
    I could have sworn I used a chr() function 40 minutes ago but can't find the file. I know it can go up to 256 so I use this: std::string chars = ""; chars += (char) 42; //etc So that's alright, but I really want to access unicode characters. Can I do (w_char) 512? Or maybe something just like the unichr() function in python, I just can't find a way to access any of those characters.
