i'm trying generate random planes in random position in screen , of random size. problem have don't understand set.position values. representing? tried search every answer couldn't find. here's code planes: var planes = []; (i = 0; < 20; i++) { var geometry = new three.planegeometry(sizewidth*((randomso(1,20)*0.00001)), sizeheight*((randomso(1,10)*0.0001))); var material = new three.meshbasicmaterial( {color: 0x00ff00}); var plane = new three.mesh(geometry, material); plane.drawmode = three.trianglesdrawmode; plane.position.set(-10+i, 0, 0); scene.add(plane); planes[i] = plane; } the x-co-ordinate in above example isn't how i'd want testing. work according screensize, each plane locate in random % of width , height. width of screen 1280 , when set the x co-ordinate let's -20 it's out of screen. should set z co-ordinate of camera differently? don't understand position co-ordinates in :-(

i having simple question, having simple batch script: for /l %%x in (1, 1, 3) start /wait c:\some.exe -verbose c:\somelog.txt del c:\somelog.txt after each execution file creates log, , want remove log before next loop execution, execution works fine when add del command having problems, looks log being deleted early. is there possible way delay del command ?? when running multiple command nest them readability. for /l %%x in (1, 1, 3) ( start /wait c:\some.exe -verbose c:\somelog.txt del c:\somelog.txt ) you way well for /l %%x in (1, 1, 3) (start /wait c:\some.exe -verbose c:\somelog.txt &del c:\somelog.txt) but not mean executable respecting wait option. many programs not. use exe directly without using start @ all.

what worst case time complexity of following: def fun(n): count=0 i=n while i>0: j in range(0,i): count+=1 i/=2 return count worst case time complexity if n big integer. o(log(n)*n) ( guessing ). here's how came conclusion. while i>0: ... i/=2 this run log(n) times because it's getting halved every time runs. for j in range(0,i): this run n times first, n/2 times 2nd time, , on. so, total running time line n + n/2 + n/4 .... 1 = (2n-1) count+=1 this cheap operation o(1). thus making total running time of function o(log(n)) * o(2n-1) , if n integer. simplifying becomes o(log(n)*(n)) .

in prolog, [h|t] list begins h , remaining elements in list t (internally represented '.'(h, '.'(…)) ). is possible define new syntax in similar fashion? example, possible define [t~h] list ends h , remaining elements in list t , , use freely [h|t] in heads , bodies of predicates? possible define e.g. <h|t> different structure lists? one can interpret question literally. list-like data structure, accessing tail can expressed without auxiliary predicate. well, these minus-lists used in first prolog system — 1 called prolog 0 , written in algol-w. example the original report, p.32 transliterated iso prolog: t(x-a-l, x-a-u-x). ?- t(nil-m-e-t-a-l, pluriel). pluriel = nil-m-e-t-a-u-x. so take left-associative operator. but, suspect, that's not wanted. want extension lists. there have been several attempts this, 1 more recent prolog iii/prolog iv . however, quite similar constraints, have face how define equality on these operat

i've got 2 questions generating numbers/single characters given distributions. how can implement laplace distribution in c++? know it's available in boost library, let's can't use it. also, don't see in standard library of c+11. if have generate text of characters normal distribution, casting generated double number int , char type trick? std::default_random_engine generator; std::normal_distribution<double> distribution(112.0,5.0); int number = (int)distribution(generator); // a-z characters if(number >= 97 && number <= 122) return (char)number; else generate once again; hope help. 1) laplace distribution has explicit density (see here ), function $\mathbf{r}$ $[0,1]$, parameters, can therefore implement in c++ member function of class member variables instance include distribution's parameters. : class laplacerandomvariable { double _b; double _mu; public: laplacerandomvariable(double b, double

i trying classify incidents true positive , false positives using machine learning. i have dataset of incidents every column describes attribute of incident. , there's list of alerts associated each incident. list of alerts can contain 0-10 alerts every alert row having details of alert. i.e there 1 many relationship between incident , alerts. i have experience in classifying simple datasets have set of columns every row not sure how handle relational data this. i using scikit-learn this. as far understand data looks this: incident table: id | i_attr0 | alerts 0 | foo | [alert0, alert1] ... alert table: id | a_attr0 alert0 | bar alert1 | baz ... if case denormalize table like: incident-alert table: id | i_attr0 | alert0 | alert0_a_attr0 | alert1 | alert1_a_attr0 | etc.. 0 | foo | true | bar | true | baz | and work there.

i want return tuple of double data types. unable create pair . have read documentation unable make it. doing private pair mynums(double f, double s) { pair<f f, s s> p = pair.create(f, s); return p; } but saying unknown class f f , s type. in case double . pair<double, double> p = pair.create(f, s);
