c - mmap an address very unlikely to be used by any other part of the program -

-
for reason, want allocate block of memory mmap using fixed address, is, map_fixed . want use address unlikely used other part of program (heap, stack etc). such address range work 64 bit system? linux attempt load elf executables @ address specified in executable, anywhere in 64-bit address space. unless give linker special options, however, build executables load @ low addresses (generally 0x0000000000400000 ), , use memory reasonable densely (there gaps between read-only , read-write sections), default heap coming afterwards. linux uses addresses in range 0x00007fff00000000 - 0x00007fffffffffff stack , 0x00007f0000000000 - 0x00007ffeffffffff shared libraries. reserves 0x8000000000000000 - 0xffffffffffffffff kernel. so means below 0x00007f0000000000 , above end of heap free, range 0x0000800000000000 - 0x7fffffffffffffff . likely, because allocations above defaults changeable if configure kernel or linker different.

javascript - MouseMove event repeating every second -

http://jsfiddle.net/mrky9/ my computer (and far, no other computer among coworkers) exhibiting issue in chrome, ie, , safari (but not in firefox). simple mousemove code, such following (already running on fiddle above) catches mousemove events, long mouse in div, catches mousemove event every second - though i'm no longer moving mouse. var number = 0; $("#foo").on("mousemove", function() { this.innerhtml = number++ }); this seems browser-based problem, since doesn't exhibit on firefox. (nor occur on windows itself. when counter going up, if leave keyboard , mouse alone, screen saver kicks in.) before concluding it's not system issue, tried replacing mouse , switching usb port it's plugged into. not surprisingly, none of solutions resolve issue. i haven't figured out how test in other javascript in browser. questions : has encountered before? there need catch it? have code far less trivial fiddle rely on knowing when mouse ...

i need amazon swf distribute work, make sure it's done asynchronously, make sure it's store in reliable way , it's automatically restarted. however, workflow logic need extremely simple: it's single task executed. i implemented way it's supposed done: request workflow execution decider founds out , schedules activity workers finds out activity request, performs results , returns results decider notices result , copies on in workflow completion it seems me can have decider work – – , complete workflow execution immediately. take care of a lot of code.

Python 3 Print Variables -

is there better way print set of variable in python3 ? in php useally did this: echo "http://$username:$password@$server:$port" but in python 3 looks ugly , longer type +'s print('http://'+username+':'+password+'@'+server+':'+port) is there in python "$" symbol ? thank you. python doesn't support string interpolation, can string formatting: 'http://{}:{}@{}:{}'.format(username, password, server, port) or keyword arguments (best used if have arguments in dictionary): 'http://{username}:{password}@{server}:{port}'.format( username=username, password=password, server=server, port=port ) you abuse locals() little, wouldn't suggest doing way: 'http://{username}:{password}@{server}:{port}'.format(**locals())
