every article i've read vouching advantages of jwt state 1 of these advantages ability auth system distributed across multiple servers. i.e . aren't relying on central repository of user auth details lookup on every request. however when comes implementation, i've read in many places added security shouldn't rely on jwt signature verification itself, , should maintain list of black or white list tokens generated server. doesn't defeat advantage i've listed above, list of tokens need stored centrally servers can access , require lookup on each request? how have people implemented on end? you making points in question. make sense store oauth token @ central location in order make easier implement signout/revoke functionality. if relied on token signature couldn't have possibly implemented such feature. suppose user wanted revoke access token. in case if didn't have central location/datastore tokens have invalidated , relied on token sig...

i new swift , have been building timer app. main (first) view controller stopwatch. recently, added view controller view splits stopwatch. problem occurs when timer has been or running , user switches second view controller , returns main view controller. instead of displaying correct stopwatch time (for example: 12:34.56), label reset default text have stopwatch (00:00.00). if resume stopwatch, restarts left off (this how intend function since user has not manually reset watch). how can display current time when switching stopwatch view controller? you store current time in global variable before going split view. then, on viewdidappear method of original view, set label correct string based on stored in variable for over-simplified example //set "00:00.00" default var currenttime: string = "00:00.00" override func viewdidappear(animated: bool){ mylabel.text = currenttime } func gotosplitview(){ currenttime = mylabel.text }

while using xcode time profile, see of function calls being performed in main thread. since they're not ui related, want move them background thread. offloading these tasks background thread improve performance of app or still same. know @ least it'd benefit updating ui. how measure performance of app using instruments, profiling module should use? thanks offloading tasks don't require main thread way go. main thread deals action demand user attention or related ui actions. i don't know mean performance when talk delegating background threads. indeed, putting forward better ui/ux performance such can't uplifted through threads. i recommend profile application , see objects creating? -monitor leaks. -consider doing time profiling. -check if i/o , cpu activities optimum. these surely nail down , performance related issues. (nb: 5% of time should go profiling app.)

i have crontab job running @ 07.00 every day. set 0 7 * * * /usr/bin/curl http://localhost//blablaba it did not work but if replace with */10 * * * * /usr/bin/curl http://localhost//blablaba then running every 10 minutes. not working if give specific time for information, have check server time , shows right time thanks :( your cron expression looks correct. follows format: minute hour day-of-month month day-of-week [user] command 0 7 * * * /usr/bin/curl http://localhost//blablaba ps: need add user field if using /etc/crontab file , not user specific crontab. so, if cron job defined in /etc/crontab file, need add user field cron job make run. if it's not case, check url on client , server side. but, think best thing debugging cron job. so, need enable logging cron jobs doing following: if on ubuntu : sudo vi /etc/rsyslog.d/50-default.conf if on centos : sudo vi /etc/rsyslog.conf uncomment li...

i use flot.js 2d plot library elm. first thought i'd write native wrapper seems discouraged. therefore want try use ports send values plot javascript (ie call flot.js made on javascript side). possible? yes, can use ports send data elm plot flot graph. here's rewrite of basic flot example using elm data source. port flotexample1 : list (list (maybe (list float))) port flotexample1 = let halfstepsto14 = list.map (\x -> x / 2) [0..28] d1 = list.map (\x -> [x, sin x]) halfstepsto14 d2 = list.map [[0, 3], [4, 8], [8, 5], [9, 13]] d3 = [just [0, 12], [7, 12], nothing, [7, 2.5], [12, 2.5]] in [ d1, d2, d3 ] elm conversion of basic elm datatypes in ports javascript types on other side. maybe in function signature above account fact nulls can used separate line segments in flot (see example d3 ) <script> var app = elm.worker(elm.main); $(function() { $.plot("#placehold...

picking programming after 8 years of... not programming (starting college soon, brushing on old knowledge). what difference between scope , encapsulation? seem rather similar. a scope area within program within automatic variables may created , @ end of automatically destroyed. examples function body or code-block of for-loop . scopes may enclose 1 , variables in outer scope may, or may not, accessible code in inner scope . for example global scope encloses other scopes , variables created in global scope visible other scopes (according various name resolution rules). therefore scope refers visibility of objects can accessed given point in program. there different types of scope each own visibility rules, example class scope refers visibility of member variables , member functions member functions of class object . for more detailed definitions see http://en.cppreference.com/w/cpp/language/scope encapsulation when hide specific data makes o...

i have modify program replace image text. in program, value of input box should reflect in place of balloon image. me ? program link: $('#draw').click(function() { var text = document.getelementbyid('txtballon').value; var $ballon = $('#ballon'), $canvas = $('#canvas'); var ballon_x = $ballon.offset().left - $canvas.offset().left, ballon_y = $ballon.offset().top - $canvas.offset().top; context.drawimage(ballon, ballon_x, ballon_y); $ballon.hide(); $(this).attr('disabled', 'disabled'); }); jsfiddle you can following way: context.font = "30px verdana"; context.filltext(text,ballon_x,ballon_y); instead of context.drawimage(ballon, ballon_x, ballon_y); working fiddle updated fiddle text drag

i new html5 , canvas element , in last few weeks have been trying understand better. anyways getting uncaught typeerror: type error when trying change red square code http://jsfiddle.net/kmhzt/10/ image http://i.imgur.com/k73egsw.png . when try uncaught typeerror: type error . here code have http://jsfiddle.net/ccdfs/ . if need me explain better ask. you're trying pass url drawimage , can't - need load image element , pass instead, after image has finished loading. this article has examples of i'm describing. the code end this: var img = new image(); img.onload = function() { context.drawimage(img, 2, 2); } img.src = 'http://i.imgur.com/k73egsw.png'; in fact, code when loads , draws tiles.

i want create macro excel (2010) substitute characters of latin alphabet equivalents cyrillic alphabet. at first glance, seems quite easy, e.g. this: activesheet.range("a1:z500").replace "sht", chrw(1097) '--> щ activesheet.range("a1:z500").replace "sht", chrw(1095) '--> Щ 'and on relevant characters , character combinations however, when run on active worksheet, not cell values affected formulae. makes them worthless, because e.g. sum(b1:b3) become Сум(Б1:Б3) [i.e. using cyrillic letters] which, excel, gibberish. therefore question: there way tell excel use replace method on cell values, not on formulae? note: dirty workaround include procedure on each cell in range first checks if starts "=", , if so, leave cell contents unchanged. perhaps there better, less home-brewed way? range.replace search in formulas. there hasformula property in range object. using must iterate on cells in given ra...
