i have 1 class named sample used in code. class sample{ . . object somemethod(){ return someobject; } . . } i call : object ob = new sample().somemethod(); i want know there advantage if create anonymous object of class( new sample() ) , call require method if don't have further use of object. benefits? i assume asking code posted contrasted following: sample s = new sample(); s.somemethod(); (where explicitly assign new sample() local variable). there's no significant performance or memory benefit 1 way or another. if store reference in local variable , invoke method, suppose there may (extremely) small performance penalty storing reference. however, suspect many compilers notice variable dead once method called , optimize away assignment. jit compiler might finish job. we're talking few cpu cycles @ most.

running test-connection ip address takes considerably longer running same command server's hostname. however; if add -quiet parameter performance same (ip fraction faster, may expect). using measure-command anomaly not show up; presumably quirk of output not being displayed. the below code more accurately reflects anomaly seen: $begin=(get-date).ticks;test-connection '123.45.67.89'; $a=((get-date).ticks - $begin) $begin=(get-date).ticks;test-connection 'myhostname'; $b=((get-date).ticks - $begin) $a-$b colleagues have reproduced same issue on machines. question: aware of may cause this? i.e. suspect it's bug (and have reported such), implies there's clever going on powershell may work differently depending on whether output displayed or not / causing quantum-like effect; it's not running commands given in order, doing (de)optimisation under covers. my environment os: ms windows 7 pro sp1 $psversioninfo : name ...

i trying use beautifulsoup 4 extract text specific tags in html document. have html has bunch of div tags following: <div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:42px; top:90px; width:195px; height:24px;"> <span style="font-family: fipxqm+arial-boldmt; font-size:12px"> futures daily market report financial gas <br/> 21-jul-2015 <br/> </span> </div> <div style="position:absolute; border: textbox 1px solid; writing-mode:lr-tb; left:54px; top:135px; width:46px; height:10px;"> <span style="font-family: fipxqm+arial-boldmt; font-size:10px"> commodity <br/> </span> </div> i trying text span tags in div tag has style of "left:54px". i can single div if use: soup = beautifulsoup(open(extracted_html_file)) print soup.find_all('div',attrs={"style":"posit...

i want generalize standard deviation function allow calculations of multiples of deviations, still use in context of piping. appears setting function incorrectly. let variance (x:seq<float>) = let mean = x |> seq.average x |> seq.map(fun x -> (x - mean) ** 2.0) |> seq.average let stddeviation (deviations:float, x:seq<float>) = sqrt (x |> variance) * deviations example usage be let stester = seq{1.0 .. 20.0} let stddev = stester |> stddeviation 1.0 i keep getting error: expression expecting have type: seq -> a' here has type float help appreciated. thanks, ~david if change stddeviation takes 2 parameters, rather tuple works: let stddeviation (deviations:float) (x:seq<float>) = sqrt (x |> variance) * deviations let stddev = stester |> stddeviation 1.0 the idea when write let stddeviation (deviations, x:seq<float>) defining function takes single parameter tuple. the way |> operator ...
