using fbsdkappinvitedialog how know when friend has accepted invitation? the result in following delegate method not give information: - (void)appinvitedialog:(fbsdkappinvitedialog *)appinvitedialog didcompletewithresults:(nsdictionary *)results{ so app know when "app friends". i know sure cannot ids or information friends invited using fbsdkappinvitedialog . more information in question: app invite dialog delegate methods result parameter contains no request id and i'm pretty sure there no way friends accepted invitation directly neither. use dynamic app link end point referral code, though. can have here: https://developers.facebook.com/docs/app-invites/ios#app_links the above applies if developing non-game app. easier if doing game. can use fbsdkgamerequestdialog or invitable_friends method of graph api, if want draw custom interface that. unrelated directly question, might interesting if trying implement kind of referral system: https://dev

this has me scratching head. the option text cleared using code in snippet: document.queryselector('option').textcontent = ''; <select> <option>ipso</option> </select> it works in codepen , plus works on website. however, in jsfiddle fails – but in chrome . if set textcontent prior clearing it, it works . this issue doesn't seem occur other type of element. if use innertext or innerhtml instead of textcontent , same behavior – again, in chrome. jquery's text() method gives same behavior. is chrome bug or jsfiddle bug? i don't know reason bug, try setting load type (click cog in top right corner of javascript frame) , select no wrap - in <body> . it works on chrome browser on phone (whilst fiddle didn't), , possibly explain what's gone wrong.

the following code works in python var=range(20) var_even = [0 if x%2==0 else x x in var] print var,var_even however, thought conditions need put in end of list. if make code var_even = [0 if x%2==0 x in var] then won't work. there reason this? there 2 distinct similar-looking syntaxes involved here, conditional expressions , list comprehension filter clauses . a conditional expression of form x if y else z . syntax isn't related list comprehensions. if want conditionally include 1 thing or different thing in list comprehension, use: var_even = [x if x%2==0 else 'odd' x in var] # ^ "if" on here "this or that" a list comprehension filter clause if thing in elem x in y if thing . part of list comprehension syntax, , goes after for clause. if want conditionally include or not include element in list comprehension, use: var_even = [x x in var if x%2==0] # ^ "if" on here "

section 2.2 of happy user manual advises use left recursion rather right recursion, because right recursion "inefficient". they're saying if try parse long sequence of items, right recursion overflow parse stack, whereas left recursion uses constant stack. canonical example given is items : item { $1 : [] } | items "," item { $3 : $1 } unfortunately, means list of items comes out backwards. now it's easy enough apply reverse @ end (although maddeningly annoying have everywhere parser called , rather once it's defined ). however, if list of items large, surely reverse also going overflow haskell stack? no? basically, how make can parse arbitrarily-large files , still results out in correct order? if want entire items reverse d every time, can define items : items_ {reverse $1} items_ : item { $1 : [] } | items_ "," item { $3 : $1 } reverse won't overflow stack.

i puzzled behavior of multiprocessing code using psycopg2 make queries in parallel postgres db. essentially, making same query (with different params) various partitions of larger table. using multiprocessing.pool fork off separate query. my multiprocessing call looks this: pool = pool(processes=num_procs) results=pool.map(run_sql, params_list) my run_sql code looks this: def run_sql(zip2): conn = get_connection() curs = conn.cursor() print "conn: %s curs:%s pid=%s" % (id(conn), id(curs), os.getpid()) ... curs.execute(qry) records = curs.fetchall() def get_connection() ... conn = psycopg2.connect(user=db_user, host=db_host, dbname=db_name, password=db_pwd) return conn so expectation each process separate db connection via call get_connection() , print id(conn) display distinct value. however, doesn't seem case , @ loss explain it. print id(curs) same. print os.getpid() shows difference.
