  • STL: writing "where" operator for a vector.

    - by Arman
    Hello, I need to find the indexes in the vector based on several boolean predicates. ex: vector<float> v; vector<int> idx; idx=where( bool_func1(v), bool_func2(v), ... ); What is the way to declare **where** function, in order to use the several user defined boolean functions over the vector? thanks Arman.

  • Cloud computing?

    - by Shawn H
    I'm an analyst and intermediate programmer working for a consulting company. Sometimes we are doing some intensive computing in Excel which can be frustrating because we have slow computers. My company does not have enough money to buy everyone new computers right now. Is there a cloud computing service that allows me to login to a high performance virtual computer from remote desktop? We are not that technical so preferrably the computer is running Windows and I can run Excel and other applications from this computer. Thanks

  • Firefox extension object instantiating

    - by Michael
    I want my javascript object to be initialized just once, so each new browser window will not create new data items, new functions, etc... usually we initialize the code at the end of main javascript using load window.addEventListener("load", main.onLoad, false); so once the second browser window opened, the initialization code will start from scratch. However, I would like to re-use the existing object on consequent browsers. Any mechanism that I can use?

  • Program compiled with MSVC 9 won't start on a vanilla SP3 XP

    - by jemper
    I installed XP on a virtual machine, updated it to SP3 and then tested a small program compiled with Visual C++ 2008 on my real computer - however it didn't start but outputted only an error saying that a problem had been detected and that a reinstall of the application (mine is 10KB in size and doesn't even have an installation) could fix the problem. What is required to run programs compiled with MSVC 9? Can I just include some dlls for it to work everywhere?

  • Is IE Collection reliable tool for testing with various versions of Internet Explorer?

    - by rsturim
    On my Windows machine -- I typically test different versions of Internet Explorer using an array of Virtual Machine instances (which obviously requires a fair amount of investment in time and money). In a pinch I have also used IETester -- which at times can be a little unreliable. However, I just discovered IE Collection and was wondering if people have used it -- and can I rely on it for web page testing purposes? Would love to know what you think.

  • gcc compiling error on Solaris 10

    - by osman toker
    I want to compile a source code, but there are some compiling errors about __sync_xxx functions (__sync_bool_compare_and_swap etc.) GCC version on machine is 3.4.3 (it must be gcc 4.1 or over for supporting atomic builtins), so I have downloaded GCC v4.6, copied it to another directory (I didn't remove v3.4.3) then change the $PATH path for GCC but it doesn't work (the same error occurs). I want to ask that is only changing gcc path with export PATH=... enough for compiling with new GCC?

  • Count number of arguments to Excel formula in VBA

    - by Abiel
    I need to use VBA to determine the number of arguments passed to an Excel formula. For instance, suppose a cell contains the formula =MyFunc($A$1, "xyz", SUM(1,2,COUNT(C1:C12)), IF(B12,1,0)). Then the counter function should return 4. Does VBA contain any built-in functions for this, or does someone have an example of a regular expression that could calculate this?

For example: Constructs Introduced from LISP If-Else Block :"The ubiquitous if-then-else structure, now taken for granted as an essential element of any programming language, was invented by McCarthy for use in Lisp, where it saw its first appearance in a more general form (the cond structure).

  • How to compile libsox with MinGW

    - by kaykun
    Hi, I'm trying to use libsox into another program of mine, but I can't seem to compile libsox with MinGW or find any places with working binaries. I downloaded the source from the official site http://sox.sourceforge.net/ but I don't know which files to include in the project to compile it. I can't compile it with all the files included in the 'src' directory and I think I only need to compile the functions listed here: http://sox.sourceforge.net/libsox.html but I can't seem to find it. Can anyone help?
