malloc(sz) returns memory alignment works object. on 32-bit x86 machines, means address value returned malloc() must evenly divisible 4. in practice, 32-bit malloc implementations return 8-byte aligned memory, meaning returned addresses evenly divisible 8. should too. (on x86-64/ia-64 machines, maximum data alignment 8, malloc implementations return 16-byte aligned memory.) i have test situation // check alignment of returned data. int main() { double* ptr = (double*) malloc(sizeof(double)); assert((uintptr_t) ptr % __alignof__(double) == 0); assert((uintptr_t) ptr % __alignof__(unsigned long long) == 0); char* ptr2 = (char*) malloc(1); assert((uintptr_t) ptr2 % __alignof__(double) == 0); assert((uintptr_t) ptr2 % __alignof__(unsigned long long) == 0); } my malloc code allocate more space user requested. first part of space used store metadata allocation, including allocated size. sizeof(metadata) % 8 == 0 but heap static char he

i'm exploring new workflow interacting remote server , ipython has many attractive properties session logging , scripting. 1 thing have not figured out yet how effective text file manipulation on remote machine. i'm aware of %load , %writefile magic commands, that's quite awkward general use. is there way %edit work when using notebook connected remote (*nix) server? best solution simple editor opens in web browser similar panes created command_name? viewer. search seems suggest doesn't exist. have found pep requesting it. i figure it's possible have %edit trigger x-windows editor open on local machine, don't see how make happen. fine answer if there's way it. i should clarify i'm not interested in executing python code in files, want edit file. i.e. %edit -x general use case.
