short question: how can setting _em_invalid exception flag on fpu result in different values? long question: in our project have turned off floating point exceptions in our release build, turned on zerodivide, invalid , overflow using _controlfp_s() in our debug build. in order catch errors if there. however, results of numerical calculations (involving optimisation algorithms, matrix inversion, monte carlo , sorts of things) consistent between debug , release build make debugging easier. i expect setting of exception flags on fpu should not affect calculated values - whether exceptions thrown or not. after working backwards through our calculations can isolate below code example shows there difference on last bit when calling log() function. this propagates 0.5% difference in resulting value. the below code give shown program output when adding new solution in visual studio 2005, windows xp , compile in debug configuration. (release give different output, that's ...

cryptojs has functions create hmac message , secret key. how can secure considering secret key must stored in plain sight in javascript source deployed on client ? anyone can take key , issue similar requests server under identity of original client of api. isn't "identity" problem hmac supposed solve ? all in all, not understand purpose of hmac in client side js since key can't kept secret. is there use case computing hmac in javascript ? javascript has webrtc 2 clients can communicate peer-to-peer, scenario clients can generate , use own "secret". there cases client -> server usable well. if server "dynamically" serving javascript insert "secret" based on clients current session/login. assuming using https (if not there man in middle slurping "secret") it's not unreasonable assume communication server signed specific "secret" (even on unsecured http) belongs client.
