is possible switch $logprovider.debugenabled([flag]); @ runtime? the current situation: the angular client load settings server @ run phase. depends on settings set method $logprovider.debugenabled([flag]) . thanks in advance, stevo the short answer is: no, not really. once application hass been configured through .config() block, no further configuration can take place after application has bootstrapped. this due way providers work; they're available @ configuration time. there might way force configuration, , manually re-inject new $log service of controllers, if there way that, i'm not sure how.

i use file dialog file name. use name in processing. problem file name contains backslash char \ , when use path in programming language must change \ character \\ . how can solve problem slash? when use path in programming language must change '\' char "\" that not true. first of all, escaping backslashes takes place adding backslash, not replacing single quotes double quotes. that's nonsensical. secondly, every programming language different many broad generalisations need in "any programming language" absurd. furthermore, in c++, when writing characters string literal need escape backslashes, because in string literals unescaped backslashes allow enter unreadable/unwriteable characters directly source code. once resulting string in memory, doesn't matter contains backslashes. you not have change anything.

i have written uialertview code textfield , want write code store whatever typed user pushable detail list. how can that? - (ibaction)newreference:(id)sender { uialertview *newreference = [[uialertview alloc] initwithtitle:@"new reference" message:@"enter name" delegate:self cancelbuttontitle:@"cancel" otherbuttontitles: @"done",nil]; newreference.alertviewstyle = uialertviewstyleplaintextinput; [newreference textfieldatindex:0].delegate = self; [newreference show]; } here go sir. per comment above, if want store data nsuserdefaults here how it: nsuserdefaults *defaults = [nsuserdefaults standarduserdefaults]; nsstring* savedata = [[newreference textfieldatindex:0] text]; [defaults setobject:savedata forkey:@"whatever key want here"]; [defaults synchronize]; then invoke or call it: nsstring* recalldata = [defaults objectforkey:@"whatever key named above"]; happy coding -

is there way current position of famo.us surface? i mean, after render tree has done thing , modifiers have been multiplied, surface exists somewhere on screen. can't figure out how ask where. seems simple enough question. specifically, i'm building kind of scroll view , need test if contained surface has moved outside of bounding box. it looks surface has _matrix property use, seems crude way of doing it. what missing?

i have read quite few articles on +, stringbuilderappend , concat. but, if have 1 single concatenation best option? str1 + str2 use string builder use string concat i looking explanation when , 2 strings involved. also when 2 strings involved complexity of string concat o(n) n length of longest string? if you're doing single concatenation, use str1 + str2 . easy read, , translated string concat compiler, fine if you're not going through loop or something. in fact, it's faster using stringbuilder if you're going concatenate strings single time. see http://blog.codinghorror.com/the-sad-tragedy-of-micro-optimization-theater/ description of why shouldn't bother using string builder if you're not looping. also when 2 strings involved complexity of string concat o(n) n length of longest string? you that. i'd it's o(n) n combined length of 2 strings, since shortest string cannot, definition, order of magnitude larger longest ...

i have lot of csv files should placed in server. so put in directory my-cookbook/files/default/ , want load csv files using dir.glob method, don't know how set proper relative path it. dir.glob("#{relative_path}/*.csv").each |file| cookbook_file "/var/foo/#{file.basename(file)}" source file.basename(file) end end i tried dir.glob("*.csv") , didn't work. how can load files in files/default directory? this isn't how chef designed used. better off putting files in git repo or remote tarball , using things git or remote_file resources download them. cookbook_file hack small, one-off things. don't use much, recommend same.

i writing node app. app interacts redis database. that, i'm using node_redis . sometimes, want execute command using line of text. in other words, want pass through without using wrapper functions. instance, may have: set mykey myvalue i love able execute without having break apart text , call client.set('mykey', 'myvalue'); there way execute command against redis in node world? if so, how? thanks! you should able use client.send_command(command_name, args, callback) send arbitrary commands redis. args can empty , in case call client.send_command('set mykey myvalue', null, cb) .

i creating singleton instance below: +(mysingleton*)sharedinstance { static mysingleton sharedobject = nil; static dispatch_once_t predicate = 0; dispatch_once(&predicate, ^{ sharedobject = [[mysingleton alloc] init]; }); return sharedobject; } what possibilities of sharedobject getting deallocated automatically? how can sure sharedobject remain in memory until app terminated? as answer rightly points out, shared singleton never deallocated. there 2 parts answer "why", both of come following line: static mysingleton * sharedobject = nil; first, static . static , when used inside of function this, modifies lifetime of variable, changing automatic , implicit default, static . means variable exists entire lifetime of program. second, declaration makes sharedobject strong reference. variables in objective-c strong default, pedantic, have written: static __strong mysingleton * sharedobject = nil; so: ha...

my previous post seemed have been unclear posting again , try explain problem more using screenshots. https://www.dropbox.com/s/4x8wktbdo7jc21m/excel-screenshot.jpg?dl=0 now, let me explain screenshots. let's take 1 of raw materials in table, rosin (column b). whenever buy more rosin, mention quanity bought , date(column a) , have total quantity of rosin bought @ bottom using formula "=sum(b80:b91)". notice number of rows @ present 11 i.e. 80 91. still buying more rosin, when have entered data in these rows. i.e. when enter dates , quantity bought. the problem i'll have keep inserting more rows in there after every few days. , if keep doing column rosin(as other raw materials) become long i'll scrolling forever. so, there way enter amount of rosin bought , date without having insert more rows. here's link excel sheet created - https://www.dropbox.com/s/iod5y7jae6grmyz/brc%20goods%20received%20stock11.xlsx?dl=0 if think ms excel not right tool ...

here question class design , code duplication. this scenario: have class having property called supportedflow. property read , return list of flowinfo object, each 1 representing flow (physical file sending external system) few attributes such flowtype (an object representing kind of flow, instance "customer flow" or "dossier flow"). some other classes in system building need know list of "supported flow type" , can reading property supportedflow of above object , applying simple linq query: supportedflow.select(p => p.flowtype).tolist() some other classes need similar list, obtained applying filter on supportedflow list means of linq object extension method where, istance list of supported flows matching criteria (example: customer - related supported flows). here question: in such scenario best design choice, adding new properties original object (such supportedflowtype or customerrelatedsupportedflows) apply proper linq query original ...

i found site escape.alf.nu . nerd sniped me hard , couldn't leave before solving or @ least knowing solutions challenges. answers blew mind. still can't solve 17, 18 , 21 , can't find on internet. 17 , 18 lead me read lot sop bypasses. bypasses (through frame names, address hashes, more recent postmessage()) require js code on both side. known can load javascript or css , maybe info out of requires specific input formats (even javascript error messages blocked in modern browsers). setting document.domain won't work though domains similar cant set on token17.alf.nu (or 18) iframe. it seems me blatant violation of sop can bypassed browser vulnerabilities (like ones found on android default browsers). against style of other challenges have 1 requires specific browser. in 18 says "i expect 1 won't work in browsers", sounds if expects work in (so not vulnerability), , more importantly - if contradicts previous level should apparently work in browsers. ...
