i'm using callhook execute classes , methods in mvc framework. no add error-handling php exception function. i'm wondering best place execute catch command. request can (of course) lead execution of multiple classes. throughout system exceptions made. (example mentioned below). function callhook() { global $urlarray; //define controllers if (strlen(strstr($urlarray[0],'popup_'))>0) { $controller = substr($urlarray[0], 6); } else { $controller = $urlarray[0]; } $querystring[] = $urlarray[1]; $urlaction = $urlarray[2]; if(!isset($controller) && empty($controller)){ $controller = 'home';} if(!isset($urlaction) || empty($urlaction)){$action = 'view';}else{$action = $urlaction;} $controllername = str_replace('-','', $controller); $controller = ucwords($controller); $model = rtrim($controller, 's'); $controller .= 'controller';

good day all i have bunch of sql files in folder. loop through each file , timestamp of file. if timestamp mathes current date, want copy file new location. here directory structure of files: c:\mfa\mfa_timestamp\mfa_timestamp.sql and example of file be: c:\mfa\mfa_20131008\mfa_20131008.sql so here code have far, not right... set currentdate=%date% /r c:\mfa\ %%g in (*.sql) set %%g=%file% %%f in (%file%) set filedatetime=%%~tf if %filedatetime:~0, 10% == %currentdate% goto same goto notsame :same copy %file% c:\newlocation goto next :notsame goto end :next any suggestions on doing wrong here? thanks @echo off setlocal enableextensions enabledelayedexpansion set "currentdate=%date:~0,10%" %%g in ("c:\mfa\*.sql") ( set "filedate=%%~tg" set "filedate=!filedate:~0,10!" if "!filedate!"=="%currentdate%" ( copy "%%~fg" "c:\newlocation" ) )

for opting is not programming question, have 1) code, 2) amount of algorithms of comparing data each row in option #1. i not asking how queries or how database should setup . i have run bit of pickle. have database follows google gtfs specs , writing automatic update program service database. the database gets overhaul once every 3 months. table least amount of rows consists of between 1-10 rows , largest table contains 7 million rows. rest have between 10 000 , 80 000. the files program download .txt files translate in table. in other words: stops.txt = database.stops. database innodb type. i have come 2 solutions. 1) every row id in several .txt documents compared in database, if nothing has changed nothing, if has changed, update. 2) insert downloaded files own tables (basically mirroring live tables) , switch table names. example: database.stop_new , database.stop switch names. another twist: overhaul done @ date defined in 1 of .txt files, means done saturday

two numpy arrays have filled follow: [0 1 2] [0 1 2] [0 1 2] [0 1 2] [0 1 2]] [[0 0 0] [1 1 1] [2 2 2] [3 3 3] [4 4 4]] or a first idea was: ax=np.zeros((5,3),np.int16) ay=np.zeros((5,3),np.int16) j in range(0,3): in range(0,5): ax[i,j]=j#filling ax x=col ay[i,j]=i#filling ay y values y=li a second idea was: bx = np.zeros((5,3),np.int16) = np.zeros((5,3),np.int16) j in range(3): bx[:,j]=j in range(5): by[i,:]=i i sure there's better way, one? jp i think using numpy.tile might better: in [422]: np.tile((0,1,2), (5,1)) out[422]: array([[0, 1, 2], [0, 1, 2], [0, 1, 2], [0, 1, 2], [0, 1, 2]]) in [473]: tile(arange(5)[:,none], 3) out[473]: array([[0, 0, 0], [1, 1, 1], [2, 2, 2], [3, 3, 3], [4, 4, 4]]) time efficiency: for small matrix of shape (5,3), for-loop faster: in [490]: timeit np.tile((0,1,2), (5,1)) 10000 loops, best of 3: 38.3 per loop in [491]

i'm trying use arrayblockingqueue cant seem syntax right , dont know i'm supposed import use it. tried this: blockingqueue<int> queue = new arrayblockingqueue<int>(100); for declaration says there error int "dimensions expected after token" both of ints. feel simple solve, may have not imported correct thing or syntax off, appreciated. thanks blockingqueue<int> java generics not cover primitive types. you'll have use integer instances. this artifact of type erasure approach taken java. cannot erase int object , actual bytecode needed work int entirely different. possible if c++ approach used instantiate template each type parameter separately, new class new bytecode.

i autocomplete show entire list when input box gets focused (no input given). auto complete match substrings without having fiddle private variables. at moment code is: autocomplete = goog.ui.ac.createsimpleautocomplete( gsa.game.gamedata.teams, team2, false); matcher=autocomplete.getmatcher(); matcher.usesimilar_=true autocomplete.setmatcher(matcher); similar matches work have set private variable (no getter or setter available). the other 1 have not been able find out; how show data when no input given (like smart select input). when textbox receives focus it'll show data since there no filter text given. these basic things 1 configure can't find in api documentation. you need create descendants of goog.ui.ac.autocomplete , goog.ui.ac.arraymatcher , goog.ui.ac.inputhandler . directly create instance of auto complete object instead of calling goog.ui.ac.createsimpleautocomplete . in goog.ui.ac.autocomplete descendant assign custom input handler , m

i have script puts bunch of variables (in case random letters through d) array, counts frequency of these variables, finds highest frequency , finds key matches frequency. $answerlist = array($a1, $a2, $a3, $a4,); $count = array_count_values($answerlist); $high_value = max($count); $high_key = array_search($high_value, $count); print_r ($high_key); however in case there 2 equal highest values, array_search returns first key. there way return both? this should it: $high_keys = array_keys($count, $high_value); from array_search docs : if needle found in haystack more once, first matching key returned. return keys matching values, use array_keys() optional search_value parameter instead.
