i have app running on google app engine , uses task queue api of heavier lifting in background. of tasks need connect cloud sql work. @ scale many tasks attempting connect cloud sql @ once. need sort of data service layer of shared client tasks aren't making individual connections cloud sql. if has ideas i'd love hear them. yes, can this, take little bit of planning, coding, , configuration in side. one idea use pull queue (instead of push queues). pull queue can schedule tasks , execute them in separate module of application. hardware of module can configured separately main module, can avoid many instances serving requests in turns allow better use connection pooling. of course, depending on traffic getting might want decide on how many concurrent backend instances want running (and connecting db) avoid/minimize contention. easier said done, here 2 resources out: app engine modules - https://developers.google.com/appengine/docs/java/modules/ pull queues...

i improve performance making views opaque appropriate. have uibutton showing red in simulator - it's red around text of button, not entire frame. in storyboard, i've enabled opaque , changed background color clear white, yet still shows red in simulator. how change green it's opaque , not trying work transparency? note uilabel s green when change background , opaque yes. i use following code in case: [button.titlelabel setopaque:yes]; [button.titlelabel setbackgroundcolor:[uicolor whitecolor]]; // or which-you-want-color obviously, should keep weak reference button. pretty works. button size smaller screenshot size.

i have collection of basic cartesian coordinates , i'd manipulate them python. example, have following box (with coordinates show corners): 0,4---4,4 0,0---4,0 i'd able find row starts (0,2) , goes (4,2). need break each coordinate separate x , y values , use basic math, or there way process coordinates (x,y) pair? example, i'd say: new_row_start_coordinate = (0,2) + (0,0) new_row_end_coordinate = new_row_start_coordinate + (0,4) sounds you're looking point class. here's simple one: class point: def __init__(self, x, y): self.x, self.y = x, y def __str__(self): return "{}, {}".format(self.x, self.y) def __neg__(self): return point(-self.x, -self.y) def __add__(self, point): return point(self.x+point.x, self.y+point.y) def __sub__(self, point): return self + -point you can things this: >>> p1 = point(1,1) >>> p2 = point(3,4) >>> print p1 + p2 4, 5 you can add many o...
