I need to check a double value for infinity in a C++ app on Linux. On most platforms this works by comparing with std::numeric_limits<double>::infinity(). However, on some old platforms (RedHat 9 for example, with gcc 3.2.2) this is not available, and std::numeric_limits<double>::has_infinity is false there. What workaround would you re...

Typically the target machines don't have graphics cards, but we can install any software components (e.g., X). Question or two: What libraries or tools might you suggest for this?

If I load a kernel module and list the loaded modules with lsmod, I can get the "use count" of the module (number of other modules with a reference to the module). Is there a way to figure out what is using a module, though? The issue is that a module I am developing insists its use count is 1 and thus I cannot use rmmod to unload it, b...
