Loading dll using loadLibrary
java,jni,64bit,environment-variables
Apparently, the loadLibrary() Documentation has managed to fool me a bit. In case of an UnsatisfiedLinkError it states UnsatisfiedLinkError - if the library does not exist. Therefore, I obviously assumed that loadLibrary() at no point was capable of seeing my specified library. That is, however, not the case as this...

Changing JS variable with Grunt for different environments

Log access to environment variables in windows

linux,bash,shell,environment-variables
Command-line arguments and environment variables both come out of the same pool of space.
