Mounting windows shares
Procedures to mount Windows shares from remote machines changed so many times during lifespan of Linux, that an attempt to do a search in Google gives a mix of solutions from using "smbmount" to "mount -t smb".
Here is the latest and greates solution. Make sure you have "smbfs" package installed and do this :
% sudo mount -t cifs //192.168.1.102/share_name /media/my_share -o \ username=theuser,password=thepass,iocharset=utf8,file_mode=0777,dir_mode=0777
With option "iocharset=utf8" it ought to handle international characters in all Windows NT-based systems. If you need to mount drives from Windows 95/98/Me, different translation options will be necessary.
see this page for more detailed explanations.

Magic of C preprocessor
Curtis Krauskopf discusses a neat trick which forces C preprocessor to merge __FILE__ and __LINE__ as one string, which isn't straightforward since __FILE__ is a string but __LINE__ is an integer.
It turns out you can solve the problem with two additional macros:
#include <stdio.h> #define STRINGIFY(x) #x #define TOSTRING(x) STRINGIFY(x) #define AT __FILE__ ":" TOSTRING(__LINE__) void error(const char *location, const char *msg) { printf("Error at %s: %s\n", location, msg); } int main(int , char**) { error(AT, "fake error"); return 0; }
Now, if only someone could find a way to merge __func__ and __LINE__ ....
