what best way convert delegate takes first parameter of derived type 1 receives base type? mean is: func<derivedtype, object> original = ...; func<basetype, object> converted = something(original); casts, of course, not work, since these 2 different types. since want pass base type method takes derived type, need add cast. if know calls converted passing derivedtype , make straightforward wrapper, this: func<basetype,object> converted = b => original((derivedtype)b); demo.

i trying create simple animated gauge charts, red points on end of each circle. whole example in here https://jsfiddle.net/yhlch8fc/3/ (please not solve text position, it's not problem). tried search on stack overflow, tutorials change starting point of alongpath animation not helping me, because path translated x,y , rotated. thing key part of code is: circle.transition().duration(_duration) .attrtween('cx', arccirclex(_mypath.node())) .attrtween('cy', arccircley(_mypath.node())); you can easy switch similar version (code stack overflow above): circle.transition().duration(_duration) .attrtween('transformation', circletween(_mypath.node())); i don't know why, seems red circle goes left side. maybe it's because original path translated , rotated. (the original version was, when try follow filling path, not work either.) instead of rotating hover path , rotate g element contains both path , circle : enter.appen

i'm developing on legacy java desktop application mixing swing , awt controls. can apply system , feel swing controls of course, can same awt ones? if not, can implement bridge in way? the basic answer "no". awt components backed native os components, either directly (via os supplied libraries) or indirectly (via awt based native components). it's possible awt linked "older" component libraries of components won't match current os "look , feel", using newer component libraries. in either case, can't effect how these components (and not through swing's , feel api). ok, might little hear say, the story of awt says "java's guitoolkit had use native widgets provided host window system, whether windows, motif, or mac. mimicking look-and-feel in java wasn't enough; had real native components."

i'm having issues when i'm in dual shot mode. i've got far: back camera mode - works perfectly front camera mode - works perfectly parallel camera mode (full preview + small window front preview) - works on devices support accessing both cameras @ same time (like samsung s4). the problem is: while having both previews display, call takepicture() method on both cameras. works on devices samsung s4 , htc m8, on lg g3 takepicture() on camera doesn't work. doesn't enter of callbacks. front picture taken correctly, camera isn't, , freezes , camera error 100, while front camera keeps working fine. i mention all above devices (s4, m8, , g3) support parallel cameras . problem @ g3 when want takepicture. i've tested on nexus 5 not support , i've implemented different approach works great (basically, take pictures 1 @ time).

is possible have lambda expression capture variable not final? i know code work if capture them, have create new variable copies non-final variable want pass lambda expression. final someclass otherobj; for(int = 0; < 10; i++) { int = i; someobject.method(() -> otherobj.process(a, a+1)) } i'd pass in 'i' instead of having create new temporary variable. you can try java8, intstream.range(0, 10).foreach(i ->{ someobject.method(() -> otherobj.process(i, i+1)) });

i have tried simple blinking led program on stm32f4 discovery board following this tutorial. however, not sure how stop running, i.e., when unplug device pc , plug in, expect reset (i might wrong too, please correct me if not case). the board keeps blinking led on connecting again. how reset original state? pointers references embedded programming helpful. if "original state" means program shipped board, can download @ st's website. you'll need program chip's flash stock binary. note programming board you're programming flash memory retain contents through power cycles.

in android project use compile 'com.squareup.okhttp:okhttp:2.2.0' i need okhttp in version 2.2.0 code work properly. have problem when add compile('io.intercom.android:intercom-sdk:1.1.2@aar') { transitive = true } because inside intercom-sdk there okhttp dependency again later version: compile 'com.squareup.okhttp:okhttp:2.4.0' which results code uses later version 2.4.0 instead of 2.2.0 want. there please way how in module can use 2.2.0 specified , let intercom use 2.4.0? you can use this: compile('io.intercom.android:intercom-sdk:1.1.2@aar') { exclude group: 'com.squareup.okhttp', module: 'okhttp' } however pay attention. if library uses methods not present in 2.2.0 release, fail.
