i want take arbitrary list of lists , "rotate" it. is, list of lists of size 3x3: #lang racket (require rackunit) (define (rotate-lol lol) (append (list (map first lol)) (list (map second lol)) (list (map third lol)))) (check-equal? (rotate-lol (list (list 'a 'b 'c) (list 'd 'e 'f) (list 'g 'h 'i))) (list (list 'a 'd 'g) (list 'b 'e 'h) (list 'c 'f 'i))) i'm thinking list-ref replace first / second / third can't quite figure out concise way this. i know there has got elegant way this. i've done inelegant solutions problem in past more domain specific, i'd solve general case, stash in personal library, , done problem. tips or solutions? it's pretty zip , don't have make since it's in srfi-1 list library : (require srfi/1) (zip '(a b c) &#

what i'm looking script can go through huge list of pictures , sort them folders. so take pictures of dogs @ shows, lets take several pictures of dog1, dogs picture automatically named in serial number format (dog1-1, dog1-2, dog1-3, etc). dog2 follow same format. i'd script can take dog1-1-10 , move them folder named dog 1. dog2-1-10 folder named dog 2, etc. how can done in python? so basically, want is: find every file in given folder take first part of each filename , use folder name if folder doesn't exist, create it move file folder repeat well, nifty! figuring out want half battle -- now, it's matter of googling , turning code. first, need folder check in: folder_path = "myfolder" now, want find every file inside folder. quick googling session turns this : import os import os.path images = [f f in os.listdir(folder_path) if os.path.isfile(os.path.join(folder_path, f))] as aside, i'm going using os.path.join fa

to google: 1) have app uses google api javascript client. prior today, able save changes existing user file that's saved on drive. however, if send put request https://content.googleapis.com/upload/drive/v2/files updated file contents, still 200 response, new file contents not persisted. (fetching file again on page refresh shows old file state.) none of app's code has changed since last working on sunday. i feel related file revisions suspect behavior? , google drive api file update new possible bug . should bug report, unable find submit google drive sdk support page says come stackoverflow. update : there's thread on google+ site google drive developers regarding issue. 2) there webpage has information on when google makes api updates and/or changes break functionality? happened last week: google drive sdk giving access users files , affected app. stackoverflow best place learn these things?

i building cmd script restore sql server database, , need know if restore worked correctly, in order perform other tasks. code: sqlcmd -s %database_server% -u user-p password-q "restore database %database% disk='i:\bakup.bak'" thanks backup command doesn't return error code. moreover, backup error can found in error log only, not in of system catalogs. there table msdb.dbo.backupset information on successful backups, though, , can used deduce whether backup errored or not. make note of current time prior taking backup, , after backup finishes use query retireve time of last successful backup: select max(backup_start_date) msdb.dbo.backupset database_name = 'database_name' if time returned less 1 recorded there errors.

i have 3 item in single row. every item quite customized. on start load 6 item means 2 rows. when scroll , reaches end of send row load 3 row. between show jerk of mili seconds. is there way load minimum 5 rows. if user scroll 2nd row load 6th row , on... please help.. if trying load network resources in uitableviewcell , better asynchronize loading resources. if try load 6th row when scroll 2nd row. guess uitableviewcell visiblecells way load more cells' resources in advance .

i have posted similar question before didn't feel got correct answer. want change position of cashapelayer position of touch located when touch moved. i'm using code can see down below. problem have animation work, not touch located. instead 20 pixels away. there way fix this? -(void)touchesbegan:(nsset *)touches withevent:(uievent *)event { nsset *alltouches = [event alltouches]; uitouch *touch = [alltouches objectatindex:0]; cgpoint currentpos = [mytouch locationinview: self]; layer = [self addcircleyellownwithradius:8 withduration:5 x:currentpos.x y:currentpos.y]; } -(void)touchesmoved:(nsset *)touches withevent:(uievent *)event { nsset *alltouches = [event alltouches]; uitouch *touch = [alltouches objectatindex:0]; cgpoint currentpos = [mytouch locationinview: self]; //set layer posotion touch position layer.position = cgpointmake(currentpos.x-8,currentpos.y-8); } -(cashapelayer *)addcircleyellownwithradius:(float)radius5 withduratio

i'm writing highly asynchronous bit of code , i'm having problems testing using specs2 , mockito. problem matchers executed before asynchronous code executes. see specs2 has await , eventually helpers - promising i'm not sure how use them. below stripped down example illustrates problem sut package example.jt import scala.concurrent._ import executioncontext.implicits.global import scala.util.{try, success, failure} trait service { def foo def bar def baz } class anothertest(svc: service) { def method(fail: boolean) { svc.baz future { thread.sleep(3000) pvt(fail) oncomplete { case success(_) => svc.foo case failure(ex) => svc.bar } } } private def pvt(fail: boolean):future[unit] = { val p = promise[unit] future { thread.sleep(2000) if (fail) p failure (new runtimeexception("failure")) else p success () } return p.future } } specs2

the aescryptoserviceprovider.legalkeysizes field shows allowed sizes in bits. however don't understand if true, how able utilise 2048 bit key length (256 bytes)? i suppose real question is, key produced size requested (larger max 32 byte), first 32 bytes (256 bits) taken in encryption/decryption process, rendering larger key size waste of space? i don't know if there way of telling what's exposed in api... any thoughts? maybe i'm looking @ in wrong way? aes can used 3 key sizes: 128, 192 , 256 bit keys. if able use larger keys 256 bit, library "lying you" i.e. bits of larger key discarded or compressed somehow. instance php mcrypt cuts size of key down largest possible size. larger key "seeds" rather common in world of cryptography. instance diffie-hellman - key agreement algorithm - generates secret larger key size required. question of extracting (concentrating) amount of entropy in key arises. if bits truncated entropy in
