i'm looking library allow me use css transitions via jquery's addclass / removeclass / toggleclass functions. i.e. want these functions nothing (other adding css class) in webkit, use jquery animations in ie. jqueryui replaces these 3 functions , comes close need, works on exact element (e.g $('#myid').addclass('foo'); doesn't animate #myid.foo .someclass ) i've looked around , can't find this, knows of 1 :) if not, solution requires: parsing stylesheets on page css transition properties matching stylesheets transitions (e.g. -webkit-transition ) storing these stylesheets on addclass , etc match current , down tree (e.g. .addedclass .someotherclass ) apply animations matched elements (or style rule) so if knows of existing solutions parse stylesheets (the text of them) or animate rule (instead of individual nodes), helpful well. looks want jquery++ jquery.animate overwrites $.fn.animate use css 3 animations if p...

in c programming language, floating point constant double type default 3.1415 double type, unless use 'f' or 'f' suffix indicate float type. i assume const float pi = 3.1415 cause warning, not. when try these under gcc -wall: float f = 3.1415926; double d = 3.1415926; printf("f: %f\n", f); printf("d: %f\n", d); f = 3.1415926f; printf("f: %f\n", f); int = 3.1415926; printf("i: %d\n", i); the result is: f: 3.141593 d: 3.141593 f: 3.141593 i: 3 the result (including double variable) lose precision, compile without warning. did compiler this? or did misunderstand something? -wall not enable warnings loss of precision, truncation of values, etc. because these warnings annoying noise , "fixing" them requires cluttering correct code heaps of ugly casts. if want warnings of nature need enable them explicitly. also, use of printf has nothing precision of actual variables, ...

i have table records user cross-profile visits , need count of distinct visits , count of new visits specified profile (:user_id) since specified unix timestamp (:time). id | user_id | visitor_id | time (unix) ====+==========+============+============= 1 | 1 | 5 | 1300000000 2 | 1 | 5 | 1300000010 3 | 1 | 8 | 1300000015 4 | 1 | 9 | 1300000020 5 | 1 | 9 | 1300000025 6 | 1 | 9 | 1300000030 so far able count of total visits, unable new ones. select count(distinct v.visitor_id) total, sum(v.time > 1300000012) new profile_visits v v.user_id = 1 returns total | new ============ 3 | 4 but required result is total | new ============ 3 | 2 you want sum(v.time > 1300000012) new . the expression either 0 or 1. count() count 0 happily 1. sum() "count" 1's. re comment: select count(t.visitor_id) total, sum(t.subto...
