i have sticky side bar , right using js have catching , staying fixed t point. when scroll need catch , not go further starting point. code far. $(window).scroll(function(e){ $el = $('.why_social'); if ($(this).scrolltop() > 735 && $el.css('position') != 'fixed'){ $('.why_social').css({'position': 'fixed', 'top': '-62px'}); } }); you should have add opposite check. should started. $(window).scroll(function(e){ $el = $('.why_social'); if ($(this).scrolltop() > 735 && $el.css('position') !== 'fixed') { $('.why_social').css({'position': 'fixed', 'top': '-62px'}); } if ($(this).scrolltop() <= 735 && $el.css('position') === 'fixed') { { $('.why_social').css({'position': ''}); // remove `position: fixed;` } }); btw: if you...

what fastest way in numpy calculate number of jumps dijkstra's algorithm uses? have 10000x10000 element connectivity matrix , use scipy.sparse.csgraph.dijkstra calculate filled distance matrix , predecessor matrix. naive solution follows: import numpy np numpy.random import rand scipy.sparse.csgraph import dijkstra def dijkway(dijkpredmat, i, j): """calculate path between 2 nodes in dijkstra matrix""" wayarr = [] while (i != j) & (j >= 0): wayarr.append(j) j = dijkpredmat[i,j] return np.array(wayarr) def jumpvec(pmat,node): """calculate number of jumps 1 node others""" jumps = np.zeros(len(pmat)) jumps[node] = -999 while 1: try: rvec = np.nonzero(jumps==0)[0] r = rvec.min() dway = dijkway(pmat, node, r) jumps[dway] = np.arange(len(dway),0,-1) except valueerror: break return jumps #...

i want build little entity framework, need information entity class type e.g dbtype(sql, mongodb), dbname, tablename, idproperty. thought about: static methods (needs reflection hard coded strings invoke type) instance methods (need instantiate type) app.config (not directly in class) class attribute (needs reflection) store in database (to entity db need data db first, seems not nice) what best , fastest method metadata entity type? attributes want this. broad topic i'll link msdn documentation: http://msdn.microsoft.com/en-us/library/z0w1kczw.aspx attributes provide powerful method of associating metadata, or declarative information, code (assemblies, types, methods, properties, , forth). essentially can create attribute class (or use existing one) , apply classes , when want can query metadata whatever information you've stored in them.

what advantage of using boost::bind in case std::for_each(participants_.begin(), participants_.end(), boost::bind(&chat_participant::deliver, _1, boost::ref(msg))); instead of for(iterator actual = participants_.begin(); actual != participants_.end(); ++actual) (*actual)->deliver(msg); link whole code (this simple server example provided boost tutorials). i think it's pre c++11, algorithms recommended on plain for-loops things. in theory, it's easier understand purpose of code, don't have understand whole loop implementation first. for_each perhaps extreme though, since for-loop implementation simplest. before lambda functions, 'boost::bind' requirement if wanted use algorithm without defining custom functor. nowadays, range-based loops, you'd this: for (auto& participant : participants) participant->deliver(msg); algorithms still better more complicated loops though (especially don't have use 'bo...

write operations on coucbahse accepts parameter cas (create , set). return result object of non-data fetching query has cas property in it. googled bit , couldn't found conceptual article it. could tell me when use cas , how it? should common work-flow of using cas ? my guess need fetch cas first write operation , pass along next write. need update using result's cas . correct me if wrong. cas stands check-and-set , , method of optimistic locking. cas value or id associated each document updated whenever document changes - bit revision id. intent instead of pessimistically locking document (and associated lock overhead) read it's cas value, , perform write if cas matches. the general use-case is: read existing document, , obtain it's current cas ( get_with_cas ) prepare new value document, assuming no-one else has modified document (and hence caused cas change). write document using check_and_set operation, providing cas value (1). step ...
