i have difficulty in understanding different between refactoring , aspect oriented programming. i understand aspect oriented programming aims increase modularity separating cross cutting concerns, includes code duplication, tangling, etc. but refactoring process of restructuring code without changing behavior , includes code duplication, etc. do understand wrong or can explain me in easy way how understand two? thank you.. aop , refactoring 2 different things. refactoring has goal improve internal qualities of code without breaking features/functionality visible user. aop @ other side programming language paradigm introducing new language constructs aspects , pointcuts modularizing cross-cutting concerns. can used refactoring code improve modularity, refactoring isn't main goal.

i trying devise way of creating application can measure object in photo - automatically. far, have come across following systems: augmented reality trigonometry + phone sensors (gyroscope) known scale item in photo (credit card, etc.) however, have couple of questions. 1) of these methods efficient, large batches? 2) how can automate process - i.e. how camera or software detect object going measured (will same, i.e. leaf), measure according either augmented reality marker, scale in photo (credit card), or trig? any input appreciated. if want detect particular object automatically (always same object i.e. stop sign) there object detection algorithms works adequately. nice example scale invariant feature transform algorithm (sift) http://docs.opencv.org/trunk/doc/py_tutorials/py_feature2d/py_sift_intro/py_sift_intro.html but have problem of photo scale typically cannot calculated single image if want high acuraccy results. can though through stereo pairs of

i'm exploring balancing options meteor. this article looks cool , says following should supported load balance meteor: mongo optailing. otherwise, may take ten seconds 1 instance of meteor updates another, because polling mongo driver used, polls-and-diffs db each ten seconds. websocket. it's clear - otherwise clients fallback http , long-polling, work, it's not cool websocket. sticky sessions 'which required sockjs'. here question comes: as understood, 'sticky sessions support' assign 1 client same server during session. essential? may happen if don't configure sticky sessions @ all? here's came myself: because meteor stores data sent client in memory, if client connects x servers, x times more memory consumed some minor (or major, if there no oplog) lag may appear same user in, say, different tabs or windows, may surprising. if sockjs reconnects , wants data persist across reconnections, gonna have bad time. i'm not sure how
