i know java's type system unsound (it fails type check constructs semantically legal) , undecidable (it fails type check construct). for instance, if copy/paste following snippet in class , compile it, compiler crash stackoverflowexception (how apt). undecidability. static class listx<t> {} static class c<p> extends listx<listx<? super c<c<p>>>> {} listx<? super c<byte>> crash = new c<byte>(); java uses wildcards type bounds, form of use-site variance. c# on other hand, uses declaration site variance annotation (with in , out keywords). known declaration-site variance weaker use-site variance (use-site variance can express declaration-site variance can, , more -- on down side, it's more verbose). so question is: c# type system sound , decidable? if not, why? is c# type system sound , decidable? it depends on restrictions put on type system. of c# type system's designers have paper on subject...

in first step of converting infix prefix can explain in simple terms why should reverse string? there alternative method convert? yes, absolutely right if have convert infix prefix have scan string right left. why not left right? if scan left right require future knowledge of operators in string. example 1 : infix : 2+3 prefix : +23 now, when convert left right should have knowledge of + yet appear in string. looks simple in particular example, consider example given below. example 2: infix : 2+3*4/5-6*7 prefix : -+2/*345*67 now, if scan left right when scan 0th index of string program should have knowledge of - going appear in 7th index of string hectic job. so safest way scan string right left.

i understand kineticjs stage can saved json stage.tojson function. perform action time stage changes in way. example, want run tojson function if shape moved via draggable, shape's size changed, inner contents changed dynamically, shape added dynamically, etc. etc. etc. prefer not listen of possible events , run same code each. prefer capture events in 1 call. there me this? realize there performance hit. saving stage upon change being made business requirement. fortunately, functionality limited few users. thank you. how save stage upon every kineticjs event? answer: call stage.tojson when kineticjs event occurs. is there kineticjs event handler listens any-and-all events? answer: actually, there 1 draconian option. you ask listen every event kineticjs can generate because .on() method can accept multiple space-delimited event types. you left task of deciding whether stage.tojson based on eventtype plus design considerations. nodes can listen ...

consider following simple program (run on gwan v4.3.14): xbuf_t buf; xbuf_init(&buf); xbuf_cat(&buf, "{\"num\":-1}"); // simple json string jsn_t *jrec = jsn_frtext(buf.ptr, "rec"); // parse jsn_t *jnum = jsn_byname(jrec, "num",1); // element jsn_updt(jnum, 2); // change value positive 2 xbuf_empty(&buf); // reuse buffer puts(jsn_totext(&buf, jrec, 0)); // lets take the expected output {"num":2} turned out {"num":-2} . somehow, jsn_totext() reused emptied xbuffer , overwrote location of '1' '2'. if jsn_update(jnum, 100) , output correct. is bug or did misunderstand functionality of xbuf_empty() ? i asking quesiton because using xbuf_reset() instead of xbuf_empty() makes code work expected. you have answered question: problem in code comes (mis)use of xbuf_empty() function. let's explain wh...

so have been working on game in html5 canvas , noticed games lags , performs slower when hardware acceleration turned on in google chrome when turned off. can try here from doing profiling see problem lies in drawimage . more drawing 1 canvas onto another. lot of this. hardware acceleration on. hardware acceleration off. is there fundamental missing 1 canvas another? why difference profound? if remember correctly, in-dom canvases loaded gpu memory in chrome, , off-dom canvases may not be. each drawimage off-screen canvas on-screen canvas results in loading content of canvas onto gpu texture, followed copy of memory on-gpu onto on-screen canvas. cost of sending new texture through gpu can quite high. loading textures high-throughput, high-latency, on gpus. someone chrome team have chime in definitive answer, fits experience canvases in chrome.

what's different between jettyrunner , full jetty distribution? is jettyrunner lack of something? if so, can add jar (like jetty-websocket.jar) classpath instead of using full distribution folder? the jetty-runner artifact way start (most?) web applications directly commandline. works around of normal conventions related webapp classloaders, etc limited feature set @ point, haven't see groundswell of response needing features websocket support @ point haven't looked @ required that. the full jetty distribution increasing becoming solid path forward more operations focused lot well, nice new features home , base directories, allowing tiers of base directory configuration letting share common configurations or libraries across multiple distinct application bases, etc... if sounds greek, should make sense normal corporate operations type person :)

the problem this: status bar intially hidden. have tab bar controller , has navigation controller in each of tabs. screen shot like: later clicked on button on navigation controller's view, reveal status bar, ends this: the navigation bar overlaps status bar. have perform actions tapping tab make navigation bar go down. i tried set status bar uistatusbarstyleblackopaque , worked fine. if press "home" button on iphone turn app bacground , switch active, problem occurs again if clicked on button. your status bar style uistatusbarstyleblacktranslucent . should set either uistatusbarstyledefault or uistatusbarstyleblackopaque desired effect. translucent status bars overlap full screen views, while opaque ones push views down.
