i work in large collaboration (of non-professional programmers, being 1 of them). regularly see examples of following void t::dochanges(i i); // make changes internal structure of t (non-const) v t::getvalue(); class { private: t* fmember; public: a(); t* getmember() const {return fmember;} } , use-case be a a; i; a->getmember()->dochanges(i); v v = a->getmember()->getvalue(); this practice violates tenant drilled me when took programming courses, i.e. const refers not bitwise structure of class instance, internal logical structure. under philosophy, member function should take following forms: t* getmember() {return fmember;} const t* getmember() const {return fmember;} i have heard people think const should refer members, speaking strictly using c++ terminology. how/why argue type of practice? making member function gives indication users of function not modify any class members. returned member may or maynot const making member functi...

my google-fu has let me down bit on this. can answer question me? to extent jquery / javascript functions stored in memory? once browser has parsed page goes memory? of it? if functions repeatedly called memory? if portion of memory allocated scripts filled (thinking ie6 on horrible pc here), happens? (other slow browser..) is there way of seeing how memory used variable or function whole? i'm curious, i've never had problems slow scripts per se, sat there thinking afternoon , realised didn't know this! h as per knowledge, once javascript code has been parsed browser, objects remain in memory unless dereferenced , garbage collected. garbage collection dependent on js implementation of browser though. you can see memory usage js objects in chrome. see here

i setting multiple sites on iis7. what pros , cons of: setting sites on same ip address different ports versus setting sites on different ip addresses. also,what implications ssl certificates(any other aspects may know of) between above 2 approaches? first, each site uses ssl, must bound ip address. ssl sites can segmented ip (and port) , cannot segmented host name. the implication segmenting host if given site goes down (literally stopped) , if there site listening on ip, "choose" site. so, effect user goes site , sees stuff site b. if sites segment on host, isn't problem. for public sites assume 80 , 443 http , https, can segment on ip or host. users not expecting navigate on different port , need open special ports on hosting system's firewall allow requests on ports.
