ruby - Arrays misbehaving -

here's code: # = array.new(3, array.new(3)) = [[nil,nil,nil],[nil,nil,nil]] a[0][0] = 1 a.each {|line| p line} with output: [1, nil, nil] [nil, nil, nil] but using commented line: [1, nil, nil] [1, nil, nil] [1, nil, nil] so why that? the commented line assigning 3 of same reference array, change 1 array propagate across other references it. as 2 arrays vs 3, that's matter of first line specifying 3 first parameter , specifying 2 array literals in second line. to create nested arrays without having shared references: a = array.new(3) {array.new(3)} when passed block ( {...} or do ... end ), array.new call block obtain value of each element of array.

javascript - Issues with offsetTop when HTML margin is applied -

-
if set css html { margin: 10px; border 10px solid #ccc; padding: 10px; } and try offsettop of element, possible convince browsers (ie , ch) not ignore document margin in calculation? firefox works expected reporting values according rendered html (uses 3 values). is there fast cross-browser way of calculating offsettop when offsetparent body . unfortunately jquery's .offset() doesn't trick here :( this code thinking , started. the idea use htmlelement.getboundingclientrect() function that's supported major browser these days (and has been quite time now). difference i've found out when running against document.documentelement element. ff , chrome don't report bottom values according view port rather whole document itself. so careful.

i have following geometry problem: given circle center in origin - c(0, 0), , radius 1. inside circle given n points represent centers of n different circles. asked find minimum radius of small circles (the radius of circles equal) in order cover boundary of large circle. the number of circles is: 3 ≤ n ≤ 10000 , problem has solved precision of p decimals 1 ≤ p ≤ 6. for example: n = 3 , p = 4 and coordinates: (0.193, 0.722) (-0.158, -0.438) (-0.068, 0.00) the radius of small circles is: 1.0686. i have following idea problem implementing it. idea consists of binary search find radius , each value given binary search try , find intersection point between small circles , large one. each intersection have result arc. next step 'project' coordinates of arcs on x axis , y axis, result being number of intervals. if reunions of intervals x , y axis have result interval [-1, 1] on each axis, means circle covered. in order avoid precision problems thought of searchin...
