i try create in windows phone timer update every 10-15 ms (for ui element). , want have opportunity append time. create timespan , dispatchertimer interval = 15 ms. every 15 ms call event subtract 15 ms timespan , when timespan <= 0 call method. when set timespan 4 seconds (for example) in life passed more 4 sec 4,6 sec. tryed use async/await did't work. tryed use system.threading don't know how update element create in other thread. so every 15 ms call event subtract 15 ms timespan , when timespan <= 0 call method. your logic flawed. can't possibly update timespan way because: as stephen cleary mentioned in answer, have no guarantee timer fire @ 15 ms even if did, doesn't take account time needed update timespan (say takes 1ms compute new timespan, timer drift of 1ms every 15ms) to have accurate time, need store timestamp @ started (retrieve using datetime.utcnow . every time timer tick, take new timestamp , substract 1 saved. way, know how

i'm trying make query checks if field 'field_a' in 'table_a' '0' , if is, update 'field_b' in 'table_b' '10'. i have no idea if possible. have little experience mysql , i'm trying things out. if is, i'd know how done. update table_b set field_b = 10 exists (select 1 table_a field_a = 0)

i developing application on android platform. app needs capture image using camera, , analyse captured image see red , blue color ends , next step make contour arround twi shape cirle , triangle.(already done ) have move next step : segmentation can me how segment images. ideas? assuming c contour: rect roi = imgproc.boundingrect(c); mat newmat = mrgba.submat(roi); bitmap bmp1 = bitmap.createbitmap(newmat.width(), newmat.height(), bitmap.config.argb_8888); utils.mattobitmap(newmat, bmp1); bmp1 should hold image want. this give rectangular image shows bounding area of original object, if circle have detected, circle plus other parts of image contained in bounding box. if just want detected object , have rest of content transparent harder problem.

for better visual experience use css style on <tr> when hovering on it. to see complete design: http://jsfiddle.net/rdje3/1/ i used: .table_test tr:hover { outline: none; border-color: #29ec24; box-shadow: 0 0 10px #29ec24; } this works fine in firefox. but in internet explorer hover gets displayed not complete (just between <td> ) , in google chrome nothing displayed. why? first of seems it's official bug chrome. stated here way setting 'display: block' on <tr> element, requires fix positioning afterwards. also, box-shadow requires use -webkit- prefix chrome. can see 'working' , malformed example here . you'll have set width of table cells yourself.

i have written library on swift sclalertview-swift , wasn't able import current project on (objective-c) is there ways import it? #import "sclalertview.swift" - 'sclalertview.swift' file not found you need import targetname-swift.h . note it's target name - other answers make mistake of using class name. this single file autogenerated header defines objective-c interfaces swift classes in project either annotated @objc or inherit nsobject . if target name contain spaces, replace them underscores (e.g. "my project" becomes "my_project-swift.h")

xamarin.forms generate greyish android application. i'd have light / white theme in android (like in ios target). does simple way switch exist? you can put theme parameter applicationattribute of main activity like this [assembly: application(icon = "@drawable/icon", theme = "@android:style/theme.holo.light")] or can put string androidmanifest.xml <application android:theme="@android:style/theme.holo.light" />

i'm troubleshooting issue server instance need root cause analysis , right believe driver express sessions. i've implemented sessions primary intra-page data storage mechanism, seems sessions not unique visitor relationship. by mean have session prefills form on "shipping information" page. however, if visit page other browsers or other machines detail first session created on server start prefilled if session data bleeding these other browser relationships. so, i'm trying understand if intention sessions unique visitor default. if not, can made unique? i'm worried because admin authentication done via sessions. yes unique visitor, sounds if code setting global state, , not sessions. may want post config using, plus setting session vars.

i'd use bash exit trap and use exec avoid spawning new process. possible? that is, #!/bin/bash touch $0.$$ trap "rm -v $0.$$" exit /bin/echo hello removes temporary file $0.$$ using bash's exit trap while #!/bin/bash touch $0.$$ trap "rm -v $0.$$" exit exec /bin/echo hello never "fires" trap (no message rm , file $0.$$ exists after completion). it, of course, makes sense trap can't fire bash no longer in control after exec . there way make work and use exec ? admittedly out of curiosity moreso practical matters. generally, no. not possible reason mention. that's boring answer though. let's @ our options workarounds: if care more exec semantics , less starting multiple processes, can arbitrary executables do: { while kill -0 $$; sleep 5; done; rm "$0.$$"; } & exec ./file which exec file , have process polling , doing cleanup when it's done. if want avoid forks , we're ex

i have strange problem. website using template , on iphone showing strange black vertical bar on right side. i installed safari , activated user agent. when set agent ipad, seeing problem, client told me on iphone. strangely when dev tools, seems outside html. causing this? have tried set html , body 100% width , overflow-x hidden, did not help. i have included screenshot: i have never seen before. be? verymuch! addition: here live example: example offline, sry somewhere, @ point, have element padding, border or margin blowing things out. couldn't track down, easy way kill off these days in style sheet (which commonly used part of standard reset): *, *:before, *:after {-moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box;} that seems fix issue, although on next project, recommend not setting fixed widths, rather use width: 100% etc, users on screens narrower 300px still have issues.

i'm trying work build flavors. in build.gradle i've defined 2 flavors, normal flavor , admin flavor. basicly admin flavor has button on main activity. i understand can define different packages/classes different flavours. there way make sort of if case add/remove piece of code depending on flavor? basicly need 2 versions of activity. don't want 2 entire different versions of activity , maintain them. so in activity do => gradle check if flavour 'admin' => if yes add code of button is possible? or need 2 different physical activities , maintain both of them when add functionality afterwards. buildconfig.flavor gives combined product flavor. if have 1 flavor dimension: productflavors { normal { } admin { } } then can check it: if (buildconfig.flavor.equals("admin")) { ... } but if have multiple flavor dimensions: flavordimensions "access", "color" productflavors { normal

what differences between apache spark , apache storm ? suitable use cases each one? apache spark in-memory distributed data analysis platform-- targeted @ speeding batch analysis jobs, iterative machine learning jobs, interactive query , graph processing. one of spark's primary distinctions use of rdds or resilient distributed datasets. rdds great pipelining parallel operators computation , are, definition, immutable, allows spark unique form of fault tolerance based on lineage information. if interested in, example, executing hadoop mapreduce job faster, spark great option (although memory requirements must considered). apache storm focused on stream processing or call complex event processing. storm implements fault tolerant method performing computation or pipelining multiple computations on event flows system. 1 might use storm transform unstructured data flows system desired format. storm , spark focused on different use cases. more "apples-to-apples&q
