i'm following hellofacebooksample project bundled facebook sdk 3.5. i've virtually copied , pasted own app, stuff appdelegate, yet reason clicking login button freezes app. record, authenticates correctly when connecting integrated framework in ios 6, done through fb sdk anyway. it's when try log in using web, i.e. hit fbloginview website opens, authenticated, return app. here code in samepl project, , i'll compare mine: fbloginview *loginview = [[fbloginview alloc] init]; loginview.frame = cgrectoffset(loginview.frame, 5, 5); loginview.delegate = self; [self.view addsubview:loginview]; [loginview sizetofit]; mine little different: loginview = [[fbloginview alloc] init]; loginview.delegate = self; [self.facebookcell addsubview:loginview]; [loginview sizetofit]; as delegate methods, i've implemented them verbatim. why app crash? there no valid reason crash when code pretty identical between app , sample app. debugger doesn't zombie objects on. ac...

i want create program generate random phrase creating 10 random integers 1 20, , depending on each variables integer, word or phrase produced. there easier way following: #this random phrase generator import random rand1 = random.randint (1, 20) rand2 = random.randint (1, 20) rand3 = random.randint (1, 20) rand4 = random.randint (1, 20) rand5 = random.randint (1, 20) rand6 = random.randint (1, 20) rand7 = random.randint (1, 20) rand8 = random.randint (1, 20) rand9 = random.randint (1, 20) rand10 = random.randint (1, 20) if rand1 ==1: print ('squirrel') and on... p.s. using python 3 thank helpful advice. new python, , helpful have people can me create better code. if cares, used program talks you, , offers chance hear jokes , play several games. have nice day. pps ended going with: import random words = 'squirrel orca ceiling crayon boot grocery jump' .split() def getrandomword(wordlist): # function returns random string passed list of strin...

i have existing site has user passwords hashed using sha1 hashing algorithm. need port users (and passwords) new meteor site. is possible? i encountered similiar problem , migrated accounts , had users reset passwords. can use built standard accounts methods handle login+reset functions. login method call: meteor.loginwithpassword(email, password, function(err){ if (err){ if(err.reason === "user has no password set"){ session.set('loginerrormessage', 'you have been migrated... reset password...'); //your template push user reset password } }else{ //normal login } }); can if have custom login form, possibly lightly customize accounts-ui package if desired this approach has worked pretty app far, users have follow password reset procedure , go

i'm constructing plot using bargraph.ci sciplot. x-axis represents categorical variable, values of variable names different positions on x-axis. unfortunately these names long, @ default settings, of them disappear. solved problem splitting them multiple lines injecting "\n" needed. worked, because names multi-line, close x-axis. need move them farther away. how? i know can mgp, affects y-axis too. i know can set axisnames=false in call barplot.ci, use axis create separate x-axis. (in fact, i'm doing that, make x-axis extend farther default- see code below.) give x-axis own mgp parameter not affect y-axis. far can tell, axis() set ordinal or continuous variables , doesn't seem work great categorical variables. after fiddling, couldn't put names in right locations (i.e. right under correspondence bars) finally, tried using mgp.axis.labels hmisc set x-axis mgp, precisely want, far tell had no effect on anything. ideas? here's code. ylim = c(...
