need specify address of char array opcodes (&opcodes)? i'm casting void pointer, see indeed specify again address (fp points address opcodes -> points opcodes). char opcodes[] = "\x41\x41..."; void main() { void(*fp) (void); fp = (void *)&opcodes; // opcodes or &opcodes fp(); } perhaps. the c standard nor c++ standard have answer this. both of them, it's undefined behavior. might vary implementation implementation, if it's possible. if give specific compiler, might able answer it.

i have array, @array , of array references. if use range operator print elements 1 through 3 of @array , print @array[1..3] , perl prints array references elements 1 through 3. why when try dereference array references indexed between 1 , 3, @{@array[1..3]} , perl dereferences , prints out last element indexed in range operator? is there way use range operator while dereferencing array? example code #!/bin/perl use strict; use warnings; @array = (); foreach $i (0..10) { push @array, [rand(1000), int(rand(3))]; } foreach $i (@array) { print "@$i\n"; } print "\n\n================\n\n"; print @{@array[1..3]}; print "\n\n================\n\n"; @{@array[1..3]} strange-looking construct. @{ ... } array dereference operator. needs reference, type of scalar. @array[ ... ] produces list. this 1 of situations need remember rule list evaluation in scalar context. rule there no general rule. each list-producing operator own thin...

not long ago asked this question. surprised no 1 came answers, pretty sure issue rare. yesterday, self-diagnosing issue, began connecting dots. twisted tcp server won't work, idle fails @ startup because of "socket error" , returns message: "idle subprocess: socket error: no connection made because target machine actively refused it", , same error when try running (local) tcp client connecting (local) tcp server. so came conclusion yesterday, these weren't individual issues, rather larger issue creating , running tcp endpoints using python sockets. keep in mind, udp servers , clients run both on local network , locally work, don't think it's problem socket module whole, tcp side of things. some info on computer: windows 64bit, running python 2.7.9 (for reason, 32bit), laptop connected network via (built in) wireless card. isp comcast (if makes difference), , router/modem (it's all-in-one) technicolor provided comcast (again, if makes dif...

i have piece of code: bincounts = [] in range(len(bins)): bincounts.append(0) where bins array looks this: ['chry', '28626328', '3064930174', '28718777', '92449', '49911'], ['chry', '28718777', '3065022623', '28797881', '79104', '49911'], ['chry', '28797881', '3065101727', '59373566', '30575685', '49912']] when run range(len(bins)) in python's interactive mode, get: [0, 1, 2] but when test whole piece of code, i'm getting [0,0,0] i believe should getting [0, 1, 2, 0] this resulting in division 0 error later on down line. why happening? how can fix it? appreciate guidance! you receiving list of zeros because of line: bincounts.append(0) each time through loop, append 0 bincount if goal put 0 @ end of list, pull line out of for loop for in range(len(bins)): # logic bincounts.append(0)...

i'm using php display data on page using echo , thought faster javascript. i'm wondering though if should passing data page via json , have javascript show data instead. think give me more flexibility. current code: <span class="label">variable: </span><?php echo $model->variable ?> with advancement in js frameworks, more practical render data via javascript these days? i advise separating javascript , html php , go structuring application in restful design. this gives high level of flexibility treating server side code api javascript on front end can make calls (using ajax) in order retrieve data. make program easier expand can work on server side , client side separately , not accidentally adversely affect other parts of application.

recently learned not advised use single vm run server applications because microsoft can take vm offline when updating causing services unavailable time. instead microsoft advises use multiple vms , place these in same cloud service , availability set. microsoft ensure @ least 1 vm stay online while updating.

i'm looking have used mmdrawercontroller . i've downloaded example project , has table view center view controller. pan gesture works correctly - starts open drawer if gesture horizontal. drawer not open when scroll table view. desired behavior me. but when set own project , there's scrollview or tableview - scrolling them , down opens drawer if scrolling gesture has slightest horizontal component confusing , barely usable. i've tried understand makes difference in example project looking through code, no success. didn't find gesture recognizer callback overrides or changing gesture behavior. i've looked through threads on considering mmdrawercontroller , didn't find similar. i know can override things in mmdrawercontroller subclass change gesture recognition , achieve desired behavior way, don't want reinvent wheel here. there easy answer overlooked. i've found origin of problem. has nothing mmdrawercontroller. in project,...

i rotate fab in such simple way: fab.startanimation(animationutils.loadanimation(this, r.anim.rotate)); rotate.xml : <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"> <rotate android:fromdegrees="0" android:todegrees="360" android:pivotx="50%" android:pivoty="50%" android:duration="1000"/> </set> this works, fab shadow rotates. need fab rotate (or src image, if there's difference). did try animate method provided compat library? had same problem when using animation utils final overshootinterpolator interpolator = new overshootinterpolator(); viewcompat.animate(fab). rotation(135f). withlayer(). setduration(300). setinterpolator(interpolator). start();
