  • Is it possible to format C++ code with VIM?

    - by Werner
    Hi, I am rather new to VIM. I got some source code and this is a mess. At a first sight I would like at least to get a clear and organised view of the code, so I like to get it rightly formatted, I mean indented depending on the depth of the functions and so. I wonder if it can be done with VIM, and otherwise which other commandline tools for that can you recommend. Thanks

  • .NET coupled with MATLAB or R?

    - by Peter
    I'm writing a program in .NET that will need to utilize the statistical and data analysis functions of R or MATLAB. I have used R but am now contemplating moving to MATLAB since it has a .Net compiler while R can only interface via COM objects. Can anyone recommend going either way? I know MATLAB is infinitely more expensive than R (since R is free) but I'm thinking that may translate to an easier development cycle?

  • Is it possible to get a graphical representation of gprof results?

    - by Werner
    Hi, I am interested in getting the profiling of some number crunching program. I compiled it with -g and -pg options and linked it and got it gmon.out. After reading the info (plain text) it looks a bit ugly. I wonder if there are some open source tools for getting a graphical representation of the 10 functions where the program spends the most of the time as well as a flux diagram. Thanks

  • [C++] Is it possible to roll a significantly faster version of sqrt

    - by John
    In an app I'm profiling, I found that in some scenarios this functions are able to take over 10% of total execution time. I've seen discussion over the years of faster sqrt implementations using sneaky floating-point trickery, but I don't know if such things are outdated on modern CPUs. MSVC++ 2008 compiler is being used, for reference... though I'd assume sqrt is not going to add much overhead though.

  • Does F# have an equivalent to Haskell's take?

    - by McMuttons
    In Haskell, there is a function "take n list" which returns the first n elements from a list. For example "sum (take 3 xs)" sums up the first three elements in the list xs. Does F# have an equivalent? I expected it to be one of the List-functions, but I can't spot anything that seems to match.

  • penalty for "inlined" classes

    - by 2di
    Hi All Visual studio allow you to create "inlined" classes (if I am not mistaken with the name). So class header and implementation all in one file. H. file contain definitions and declarations of the class and functions, there is no .cpp file at all. So I was wondering if there is any penalty for doing it that way? any disadvantages ? Thanks a lot

  • Passing around an ElementTree

    - by PulpFiction
    Hello. In my program, I need to make use of an ElementTree object in various functions in my program. More specifically, I am doing this: tree = etree.parse('somefile.xml') I am passing this tree around in my program. I was wondering whether this is a good approach, or can I do this: Create a global tree (I come from a C++ background and I know global is bad) Create the tree again wherever required. Or is my approach ok?

  • Can we write an EOF character ourselves?

    - by Apoorv
    Most of the languages like C++ when writing into a file, put an EOF character even if we miss to write statements like : filestream.close However is there any way, we can put the EOF character according to our requirement, in C++, for an instance. Or any other method we may use apart from using the functions provided in C++. If you need to ask more of information then kindly do give a comment. Thanks in advance.

  • Receiving data from a USB device in C or C++

    - by Midas
    It starts to bore me that I always have to ask questions about trifles. I simply need a list of all plugged in USB devices and have the user select one to let the console application receive any data the USB device sends. I can then start playing around with the data in my program. I don't want to use library's, only standard C++ functions, and the program should work in Windows 98.

  • Why can't I make my parameter like this?

    - by mystify
    - (void)setPropertyValue:(const *void)inValue forID:(UInt32)propertyID { } The compiler doesn't like the const *void, for some reason. When I have that, it says: error: expected ')' before 'void' When I make the parameter like (UInt32)foo there is no problem. Does const *void only work in functions? I need a parameter which can be a "pointer to anything" like UInt32, Float64, etc.

  • How to get parallel behavior in Java Script ?

    - by Biswanath
    More or less I want to execute two functions in parallel. One way as I see is doing through SetTimeOut function. I have not completely gone through the ReactiveExentension, although it looks promising but may be overkill for my needs. Is there any framework which supports parallelism ? My use case is trivial, but I would like to know if anybody heavily needed parallelism in Java Script ? Thanks, Biswanath.

  • Why does string::find return size_type and not an iterator?

    - by dehmann
    In C++, why does string::find return size_type and not an iterator? It would make sense because functions like string::replace or string::insert take iterators as input, so you could find some character and immediately pass the returned iterator to replace, etc. Also, std::find returns an iterator -- why is std::string::find different?
