Here is my question: #data 1: lab1 <- 1:10 group <- rep(1:3, each = length (lab1)) label <- rep(lab1, 3) avar <- rep(c(0, 1, 4, 5, 6, 8, 10, 11, 12, 13), 3) myd <- data.frame (group, label, avar) # data 2 fillcol <- rep(rnorm(length(lab1)-1, 0.5, 0.2), 3) group1 <- rep(1:3, each = length(fillcol)/3) # this variable will be used to fill color in bars filld <- data.frame(group1, fillcol) # now plotting par(mfrow = c(3, 1)) par(mar = c(2.5, 1, 2.5, 1)) #plot1 myd1 <- myd[myd$group ==1,] filld1 <- filld[filld$group1 ==1,] blues <- colorRampPalette(c("yellow", "blue")) barplot(as.matrix(diff(myd1

This question already has answers here : Django - How to make a variable available to all templates? (2 answers) I am trying to pass variables (browser variable) to all my templates in my app. Any advice on how to get it to work? View: def browser(request): primary_cat_list = Categories.objects.order_by("category") subcat_list = SubCategories.objects.order_by("sub_category") product = Productbackup.objects.order_by("website") browser = list(chain(primary_cat_list, subcat_list, product)) return render_to_response('reserve/templates/base.html', locals(), context_instance=RequestContext(request))

Is there any fast way to find the largest power of 10 smaller than a given number? I'm using this algorithm, at the moment, but something inside myself dies anytime I see it: 10**( int( math.log10(x) ) ) # python pow( 10, (int) log10(x) ) // C I could implement simple log10 and pow functions for my problems with one loop each, but still I'm wondering if there is some bit magic for decimal numbers. An alternative algorithm is: i = 1; while((i * 10) < x) i *= 10; Log and power are expensive operations. If you want fast, you probably want to look up the IEEE binary exponent in table to get the

I might be assuming a lot, but rails SHOULD automatically compile all the files in those directories because of *= require_tree . in application.css, right? I recently have tried restructuring these files by removing all color variables and

I was reading it somewhere and found following: class Base { public: Base() //Default Ctor Base(int t) //Parameterized Ctor Base(const Base& b) //Copy Ctor Base(Base&& b) //Move Ctor }; void foo(Base b) //Function 1 {} void foo(Base& b) //Function 2 {} int main() { Base b(10); foo(b); -- Line 1 (i know of ambiquity but lets ignore for understanding purpose) foo(Base()); -- Line 2 foo(2) ; -- Line 3 } Now with my limited understanding, my observations are as follows : Line 1 will simply call
