(i talking milliseconds, still...). sample o/p: 6.053819752878553 9.16106501362151 5.987994283801299 is there anyway make these outputs have lesser variance each other? not asking code above, there better alternative profiler? there development environment (i using latest chrome, not many extensions)?

i think have basic grasp of monads , monadic operations still bit stuck on understanding how magic features of monadic type added underlying type (hope makes sense). for example, was reading how list[t] monad. if flatmap , map on lists sequentially in for comprehension isn't flatmap , map providing monadic magic? if create list<string> how monadic magic added? or list<t> monad in scala because happens 1 of containers language provides in-built monadic support for? you're right flatmap , map providing "monadic magic." there fortunately or unfortunately (depending on how bad code you've seen) no magic in programming. no amount of abstraction save (or else) writing code thing want. abstraction "just" lets re-use written code , clarify thoughts around problem. monad concept, idea, abstraction, etc. in case of scala literally compiler for comprehension, becomes series of flatmap , map , withfilter , , filter stateme...

as question manually setting proxy google youtube v3 api has not yielded results. thought ask seperate question causes of proxy not being used are. as stated in other question, have set following in web.config: <defaultproxy usedefaultcredentials="false" enabled="true"> <proxy usesystemdefault="false" proxyaddress="http://192.111.111.102:8081" /> </defaultproxy> which accounts should mean google api use proxy , port stated yet still getting connection refused error. having looked systems team, looks if request google api doesn't hit proxy @ all. so new question cause setting ignored , there other way of setting default proxy? not sure stopping default proxy being used work randomly not on other occasions, in end went coding in redundancy when default proxy failed work: private videolistresponse getvideolistreponse(string videoids) { // original call videolistresponse response = getvideo...

i have google script needs 2 specific dates. 1) second day of previous month @ 8 gmt 2) first day of current month @ 8 gmt both dates need converted epoch times. i built on js fiddle : var = new date(); var year = a.getfullyear(); var month = a.getmonth(); if(month === 0){ var startdate = new date((year-1)+'-12-02 08:00 gmt'); var enddate = new date(year+'-'+(month+1)+'-01 08:00 gmt'); }else{ var startdate = new date(year+'-'+month+'-02 08:00 gmt'); var enddate = new date(year+'-'+(month+1)+'-01 08:00 gmt'); } this works fine, when use in google script, new date() fails , returns nan. i've read has js version google script uses, couldn't find on how format string above go through cleanly. what correct format? 1) replace - in date string / . 2) epoc date.gettime() /1000

i'm creating modal bootstrap & ok. thing noticed bootstrap prevent overflowing of body tag when modal opens modal has property overflow if content in modal more height of screen ..., how did ? added overflow: hidden; body when modal opens & overflow: auto; modal, doesn't work ... basically, once take html element out of normal flow of elements, it's father element shouldn't effect element itself. so, body has overflow: hidden; , since overlay positioned outside of flow, overflow doesn't effect it. since .overlay have overflow-y: auto , scroll should appear content of element. so, once element positioned position: absolute or position: fixed , shouldn't effected it's predecessor's overflow body { overflow: hidden; } .overlay { position: absolute; top: 0; right: 0; bottom: 0; left: 0; overflow-y: auto; padding: 30px; background: rgba(0, 0, 0, 0.5); } .modal { marg...
