(it creates circular reference not allowed). what guys think best solution? should put business logic it's own project? so instead of: hello.data hello.business i'll have: hello.data hello.business hello.businesslogic or thinking wrong? thanks! why separate business logic business models? logic should in models. the business logic layer shouldn't have reference anything, aside maybe...

i've been unable access simple pieces of html using cheerio, finished opening object $(this) object , tracking down need. error occurs when there no object in stack, sibling or child. what's correct way select previous sibling, it's name, href & content, parent's css. var code = $('code.lang-javascript, code.lang-js') dataset.blocks = [] code.map(function (i, elm) { var block = {} block.prevsiblingtag = $(this).parent().prev()[0].children[0].name block.prevsiblinghref = $(this).parent().prev()[0].children[0].attribs.href block.prevsiblingcontent = $(this).parent().prev()[0].children[0].text() block.parenttag = $(this)[0].name block.parentclass = $(this)[0].attribs.class block.code = $(this).html() dataset.blocks.push(block) }) i doing , mess. var $parent = $($(this).parent().html()) var $prevsibling = $($(this).parents().prev()) var block = {} block.parentclass = $parent.attr('class') block.prevsibling = $prevsibling.html()...

i working on multi-level marketing (binary) looks this: (but binary tree not required perfect. node can have 0-2 child) my problem data fetch database flat list. notice using hierarchyid (sql server 2014) basically textnode column breadcrumb. every slash / represents level . if have textnode of /1/ root. every node starts /1/ belongs root /1/ , /1/1/ , /1/1/1/ (the root node included level 0) i've tried accepted answer in question not working. how can transform flatlist binary tree can traverse , display on screen? im using c#, asp mvc 5, sql server 2014 if matters. here simple implementation (assuming nodes in right order), may enhanced in multiple ways public interface irow<out t> { string textnode { get; } t value { get; } } public class treenode<t> { private struct nodedescriptor { public int level { get; } public int parentindex { get; } public nodedescriptor(irow<t> row) ...

have been playing around basic 3d. i'm trying keep math relatively simple i'm in year 9. background info: have 3 int[] variables called xpoints , ypoints , zpoints . thinking putting them in 1 list called nodes decided it's easier not to. the first forumla tried was: xpoints[i] = (int) (r*math.cos(math.toradians(d))); ypoints[i] = (int) (r*math.sin(math.toradians(d))); this worked rotating cube around 1 axis not others. found formula looked promising multiple axis can't work. faces seem shrink during each loop, ending in single point (the centre). xpoints[i] = (int) (x * cos_t - y * sin_t) ypoints[i] = (int) (y * cos_t + x * sin_t) the full function applying math: public void rotatez(double theta){ theta = math.toradians(theta); double cos_t = math.cos(theta); double sin_t = math.sin(theta); (int = 0; < xpoints.length; i++){ double x = xpoints[i] - x_off; double y = ypoints[i] - y_off - ypoints_mod[i]; xpoi...
