• This is a valid C code but not a valid C++ code?

  - by claws

  In some library I'm using (written in C) its StorePGM(image, width, height, filename) char *image; int width, height; char *filename; { // something something } All functions are defined this way. I never seen such function definitions in my life. They seem to be valid to MSVC but when I compile it as C++ it gives errors. What is it? some kind of old version C?

• Why subtract a value from itself (x - x) in Python?

  - by endolith

  In NumPy functions, there are often initial lines that do checking of variable types, forcing them to be certain types, etc. Can someone explain the point of these lines? What does subtracting a value from itself do? t,w = asarray(t), asarray(duty) w = asarray(w + (t-t)) t = asarray(t + (w-w))

• Initiatives to namespace PHP core and libraries

  - by James Maroney

  With the introduction of Object-Oriented and Namespacing capabilities in PHP, I am loving the new found cleanliness of PHP code that can be produced. The annoying thing though is that the core of PHP is still cluttered, unorganized mess of functions. Are there any initiatives to organize the PHP core and "common" libraries into namespaces and classes?

• Is it possible to unpage all memory in Windows?

  - by Hack59

  I have plenty of RAM, however, after starting and finishing a large number of processes, it seems that most of the applications' virtual memory has been paged to disk, and switching to any of the older processes requires a very long time to load the memory back into RAM. Is there a way, either via Windows API or via kernel call, to get Windows to unpage all (or as much as possible) memory? Maybe by stepping through the list of running processes and get the memory manager to unpage each process's memory?

• Is C really "disguised assembly"?

  - by regn

  As a C++ programmer I have now decided to learn C to have "more control" over what I write. Are there any syntactical features in C which lead to rather unpredictable assembler code? Like virtual functions in C++ Is C disguised assembler? I would quite like that idea.

• How do you implement the Decorator pattern if you can't inherit from the class you want to decorate?

  - by Lennie

  Hi, This is more a design question... You can't do a decorate design pattern if: 1) The object is marked "sealed" meaning you can't extend from it. 2) or you want to override a method but its not virtual. What can you do then? Taken that you can't change the class source code if you don't have the source code (like a 3rd party library).

  Hi everyone! Out of curiosity about reverse engineering, I am thinking of writing a simple program (in C++) that takes an executable as input and produces the names of all the functions that were a part of source program of that executable.

• 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?

• Two quick Mathematica questions

  - by sciguy

  How do I remove the numbers on the x-axis only not the y-axis? Is it possible to shift the y-axis without shifting the functions? What I mean is, instead of having the y-axis at x = 0, could I have it at x = -5?

• Script to parse emails for attachments

  - by Swanny

  I am looking for a way to monitor a Linux mbox email account, when an email arrives I would like to download an attachment from the email and save the attachment (CSV file) so that it may be used by a PHP script. What would be the best way of going about this? I have looked at PHP's IMAP functions but this does not appear to be the most appropriate method when a simple bash script may be all that is required?

• How do I bring a processes window to the foreground on X Windows? (C++)

  - by Lorenz03Tx

  I have the PID for the process (and the name), I want to bring it to the front on linux (ubuntu). On mac I would simply do SetFrontProcess(pid), on windows I'd enumerate the windows pick out the one I wanted and call SetWindowPos(hwnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE); but I'm at a loss of what to do on linux. I've looked at X Lib a bit, but most/all of those functions seem to operate on windows inside your process. Thanks in advanced.
