i have been many interviews, question interviewers used ask "do know virtual function?" wonder why experienced programmer/developer use function virtual. know.. not functions can virtual, functions part of class/struct can virtual. so think "function superset , method subset. not functions can methods but, methods functions. therefore appropriate use "virtual method" not "virtual function". can explain, why of experienced programmer , technical books write use "virtual function" not "virtual method"? technically methods belong classes , functions ones don't, other things general , common, people end mixing terminology , in end "function" , "method" can both refer 1 thing or other. that's pretty answer question... in end, terminology defined how people use it, not original intended meanings.

i have been exploring gps data mining literature esp. problems anomalous trajectory detection, time travel prediction, etc , 1 common method see dividing data or map grids. can 1 please explain logic of this? coordinates euclidean in case? grid decomposition necessary? grateful if can give/ quote links or materials should explore. new field, please pardon me if question obvious. thanks & regards, lesnar no not euclidean. don't have be. grids not rectangles anymore, can treated such operations. if create lat/long grid, each cell means of meters not rectangular. defines zone add counter, has clear inside/outside definition. , can use cartesian operations (rectangle.inside()) so lat / lon span constant each cell, not longitudinal meters span, shrinks cos(latitude). if 1 needs grid equal grid cells sizes means of meters, 1 has transform geo coordinates before.

i've created user custom class in bundle. inherits baseuser class of fosuserbundle. in class, i've defined several attributes entities of bundle, adress, avis etc. i have defined formtype of forms data_class user. allows me retrieve interesting user information username (!) , displaying in forms. when validate forms asks me fill plainpassword field of user class mandatory attribute. first wanted retrieve password database fill in form before displaying seems impossible security measure. i've tried stock in session (ugly know) after registration seems not possible force form data value (surely because password type field)... so question : ? but purpose of retrieving it? want modify of user's data username or email? remember can have /profile 'module' in fosuser bundle, used modifing example username , email. changing password have separate 'module' change password (i don't remember path). maybe that's looking for? of course w...

in code have function needs return either string or none depending on present in database. @ moment result list string answer inside, or none. there change made result in string or none being returned, rather having index list? here code: def retrieve_player_name(username): param = [(username)] command = (""" select username players username = ? """) result = cur.execute(command, param).fetchone() if result not none: return result[0] thanks in advance. a database cursors fetches entire rows, not values. row single value inside still row. if don't want write row[0] multiple times, create helper function execute_and_return_a_single_value_from_query() .
