• dlopen and global variables in C/C++

  - by mjn12

  Due to some restrictions I am being forced to load a library written in C at runtime. A third party provides two library to me as static archives which we turn into shared objects. The application I'm working with loads one of the libraries at runtime based on some hardware parameters. Unfortunately one of the libraries is configured largely with global variables. I am already using dlsym to load function references but can I used dlsym to load references to these global variables as well?

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

  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.

• Prompt with UAC when user doesn't have access to copy a file

  - by Will Eddins

  In my application, if the user saves a file to a folder they don't have permissions for, File.Copy will fail. An example is saving a document to the C:\ root. Instead of denying access, I'd like to prompt the user to elevate permissions with a UAC prompt, but only for this save function (not for the entire application). Is there a way to do this?

• merging indexed array in Python

  - by leon

  Suppose that I have two numpy arrays of the form x = [[1,2] [2,4] [3,6] [4,NaN] [5,10]] y = [[0,-5] [1,0] [2,5] [5,20] [6,25]] is there an efficient way to merge them such that I have xmy = [[0, NaN, -5 ] [1, 2, 0 ] [2, 4, 5 ] [3, 6, NaN] [4, NaN, NaN] [5, 10, 20 ] [6, NaN, 25 ] I can implement a simple function using search to find the index but this is not elegant and potentially inefficient for a lot of arrays and large dimensions. Any pointer is appreciated.

• How can I strip invalid XML characters from strings in Perl?

  - by AndrewR

  I'm looking for what the standard, approved, and robust way of stripping invalid characters from strings before writing them to an XML file. I'm talking here about blocks of text containing backspace (^H) and formfeed characters etc. There has to be a standard library/module function for doing this but I can't find it. I'm using XML::LibXML to build a DOM tree that I then serialize to disk.

• How to select every node that holds the same ID

  Hello, I have a Jstree that holds a lot of nodes, some of them have the same ID.

• Do I need to cast the result of strtol to int?

  - by Kristo

  The following code does not give a warning with g++ 4.1.1 and -Wall. int octalStrToInt(const std::string& s) { return strtol(s.c_str(), 0, 8); } I was expecting a warning because strtol returns a long int but my function is only returning a plain int. Might other compilers emit a warning here? Should I cast the return value to int in this case as a good practice?
