can use data annotations / validation ajax / jquery call? if so, please provide example or post shows example. basically have seen example of how use data annotations, full post back. there way ajax / jquery call? not sure how since not sure how construct model object on client side.

i understand question might sound stupid, , there might in language definition explicitly prohibits notion, since don't know prohibition, wondering whether shed light on it. in short, define python function call python shell, avoid brackets. there cases when function not require argument, , bracket seems indicate dealing function. such example be, if 1 wants print current working directory. can define function as def pwd(): print os.getcwd() and can call shell pwd() but if have function can call pwd is possible @ all? you can't without modifying language or shell. if want use python shell, should try ipython , allows define macros can use without typing many keys. lets !pwd , can assign variable x = !pwd . lets call single argument functions writing f x instead of f(x) . btw haskell language uses spaces list of arguments, i.e: f(1,2,3) in python f 1 2 3 in haskell, , in shell io action can executed typing action . i forgot there's hack ...

i started taking c++ class @ local college , instructor gave class assignment in must create vector , remove element middle of stack. she provided example: vect[3] = vect[vect.size()-1]; vect.pop_back(); now.. i've tested , works i'm unsure how works or why works. i'm sure provide simple explanation? you want delete element middle of vector, overwrite last element (with index size()-1 ) - since last element becomes redundant, can pop_back() it. have desired result - vector size decreased 1 , old value @ vect[3] gone. note doesn't preserve order of elements in vector, relatively efficient - erasing middle of vector may involve lot of memory copying since elements after element deleted need shifted 1 accommodate gap (remember: std::vector stores elements in continuous storage). erasing end costs nothing.

i believe can set layout_width , layout_height textview element dynamically using like: layoutparams lparams = new layoutparams(layoutparams.wrap_content, layoutparams.fill_parent); centimeterlayout.addview(textview, lparams); but - how set layout width , height in other units - e.g. want set layout width of text view 20 mm. how do that? layoutparams either take 1 of constants ( fill_parent , wrap_content ) or pixel value. since want use millimeters, have convert millimeter dimension pixel dimension. doing pretty easy: resources r = getresources(); float px = typedvalue.applydimension(typedvalue.complex_unit_mm, 20, r.getdisplaymetrics()); in example, 20 mm converted pixel dimension can use in layoutparams . can use other dimensions too, such typedvalue.complex_unit_dip dp/dip¹. change constant in arguments. android doc has list of useable dimensions . ¹ density independend pixels, highly recommended dimension adjusts many...

possible duplicate: fast algorithm polar -> cartesian conversion i running pathfinding code (which bit slow) through jvisualvm, found 80% time being spent in vector implementation more part convert cartesian polar, r = math.sqrt((x * x) + (y * y)); t = math.atan2(y,x); are there old school tricks me more performance? in experience in path finding algorithms, problem not lines. the main questions "how many times call these 2 lines?" you should investigate path finding algorithm. anyway, if want reduce delay of lines, possible make pre-calculated table sqrt , atan2 each x , y . or table maps each (x, y) (r, t) directly.
