how define multiple arguments? types supported? , why fail when combine decorator? i couldn't find real documentation on went source -- pysideslot.cpp . slot takes 2 keyword args, name (a string name slot) , result (a python type object or string naming qt type, used specify return type of function). if name isn't supplied, try read function you're decorating, careful: other decorators ruin name of function, if you're combining slot decorator may want explicitly specify name arg. any positional arguments feed slot converted strings pyside::signal::gettypename , joined comma-separated string. become signature of slot , used routing calls. for example, given decorator: @qtcore.slot(int,str,result=float) def func(a,b): assert len(b)==a; upload(b); return 2.5 the pyside internals create call signature string of 'int,qstring' , resulttype string of 'double'. i hope helps next person struggling debug slots.

i have java program has loop in checks new messages every twenty seconds. example: while (true) { thread.sleep(20000); newmessages(); } this works when computer being run. however, if user put computer sleep , wake duration of time later, whole program gets messed , no longer checks messages every twenty seconds. there way correct this? instead of using thread.sleep can use timer . a facility threads schedule tasks future execution in background thread. tasks may scheduled one-time execution, or repeated execution @ regular intervals. your code might be: final timer timer = new timer(); final timertask task = new timertask() { @override public void run() { newmessages(); } }; timer.scheduleatfixedrate(task, new date(), 20000); timer javadoc

trying font-weight gracefully transition '400' '600' using css doesn't appear working in chrome. known bug or doing wrong? check fiddle here example the problem font weights, when represented numerically, must multiple of 100. animate between 400 , 600, font change 400 500 600 (3 'frames', if like) , wouldn't smooth. animation wouldn't increment weight 1 each time (400, 401, 402...) increment weight 100 (400, 500, 600). if animation lasted 2 seconds, after 1 second weight become 500, , after 2 seconds weight become 600; there no in-between variations. a further problem you're attempting here font you're using (or jsfiddle's default, @ least) doesn't have different font-weight:500 , meaning defaults 400: <p style="font-weight:400;">a - 400, normal</p> <p style="font-weight:500;">a - 500 (no support, defaults 400)</p> <p style="font-weight:600;">a - 600 (bo...

i have following code, based on http://nodejs.org/docs/v0.6.9/api/crypto.html#randombytes crypto.randombytes 32, (ex, buf) -> user.tokenstring = buf.tostring("hex") user.tokenexpires = date.now() + token_time next() i using generate tokenstring use node.js/express user validation. in cases tokenstring generated includes '/' forward slash character, , breaks routes, example, tokenstring if tokenstring ' $2a$10$oyjn2r/ts.guywqx7ijtwo8cij80m.uiqv9njgtt18nqu8lt8oqpe ' can't find /user/activate/$2a$10$oyjn2r , 404 error is there more direct way exclude characters being included when generating crypto.randombytes? crypto.randombytes generates random bytes . has nothing characters, characters determined way look @ bytes. for example: user.tokenstring = buf.tostring("hex") would convert buffer string (where 2 characters represent each byte), in character range 0-9a-f another (might more suiting approach use more c...

in short, how let alert(1) run first: $.post('example.php', function() { alert(1); }) alert(2); alert(3); alert(4); but jquery ajax call seem run in asynchronous method. javascript run below first, alert(2) alert(4), post method, alert(1). certainly can put code in ajax function, make no sense when have dozens of functions, have add code functions. $.post('example.php', function() { alert(1); example(); }) function example() { alert(2); alert(3); alert(4); } i want json data ajax call, , use later. there smart solution? in jquery prefer use $.when , $.then it's easy , code more readable using this. function catchthefish(){ console.log('we catching fish'); } function eatthefish(){ console.log('now time eat fish'); } $.when ( catchthefish() ).then( eatthefish() ); this code work in latest version of jquery 1.9.1

is there docset boost? i'ld add dash offline documentation search, , can't find 1 anywhere. attempts of own build have failed, rather spectacularly. not i've found; don't offer complete set of offline docs, let alone dash docset. (alas, pdfs marchall clow mentions small subset.) i've been toying idea of creating one, gave in frustration. if want collaborate, drop me line! as understand it, you'd need to: create offline mirror of entire set of boost docs. easy enough, following should work: wget --mirror -p --no-parent --convert-links -p ./boost_docs \ http://www.boost.org/doc/libs/1_53_0/libs/libraries.htm index docs. (this hard part.) scrape html , try , pull out interesting semantic elements: classes, functions, types , on, , create index. many of components of boost seem use consistent documentation format, complicates things many other components have own, idiosyncratic approach, , html markup not semantic.

i wondering if had suggestions test coding lines in windows. right now, using repl.it i used use fxri, doesn't work in later versions , feel irb lacks lot of useful tools fxri has (example:built in, accessible library descriptions of commands) any appreciated. the pry tool great learning resource. can view source code , documentation on demand, , trivially explore library or program using intuitive file system metaphor.

i have searched forum , found many useful answers, 1 of answers used works under conditions. i populating week calendar, , need determine start of week (monday) date picker, , add date populate text fields following 6 days. works if date picker selection in same month. so, if select wednesday may 15th 2013, correctly returns , populates monday may 13, tuesday may 14, etc. but, if select wednesday may 1, 2013, correctly populates monday apr 29, tuesday puts may 30 (adding month instead of day). i should note building in application craft, don't know if has impact. here's code: var curr = new date(app.getvalue("datepicker2")); // selected date var first = curr.getdate() - curr.getday() +1; // adjust monday start of week var firstday = new date(curr.setdate(first)); var secondday = new date(); secondday.setdate(firstday.getdate()+1); can see have gone wrong? thanks tammy here secondday.setdate(firstday.getdate()+1) since specifying dat...
