my current work flow requires me rebuild rust compiler every day "standard crates" libstd target platform ( arm-unknown-linux-gnueabihf ). this not ideal. use nightly compiler, able target arm platform, not include standard libraries arm, host machines platform. how can build libraries source, without building whole compiler toolchain 3 compiler stages, llvm, jemalloc, etc...? can't i'm 100% sure, might work. run: rustc -v --version make note of commit-hash, navigate rust src folder , run: git checkout *your commit-hash* finally compile with: rustc -o --target=arm-unknown-linux-gnueabihf rust/src/libstd/lib.rs this should compile library current working directory. see http://spin.atomicobject.com/2015/02/20/rust-language-c-embedded/ original, , more detailed explanation.

for application working on, have usercontrol added form programatically several times. part of usercontrol richtextbox set transparent , has click functionality disabled acts more label , blends user control. when user control deliberately clicked user, richtextbox's background changed white, isreadonly set false, , clicking enabled. the problem trying correct user still has click on richtextbox second time enable caret prior typing. googling , code attempts programatically set caret haven't worked. suggestions why below code isn't working? there else need do? contentbox.ishittestvisible = true; contentbox.background = new solidcolorbrush(color.fromrgb(240, 240, 240)); contentbox.isreadonly = false; //manage caret position textpointer newpointer = contentbox.caretposition; newpointer = newpointer.documentend; contentbox.caretposition = newpointer; i think missing setting logical , keyboard focus control afterwards. try dispatcher.begininvoke(

i'm creating simple authentication system in laravel 5. have authentication code written in laravel 4 i'm using foundation. my problem is, sqlstate[42s22]: column not found: 1054 unknown column 'confirmed' in 'where clause' (sql: select * users email = myemail@gmail.com , confirmed = 1 limit 1) it looks laravel looking see if email verified. not need implement sign-up , verification process application. question is, how tell laravel not worry email confirmation? my authentication code looks this: public function postauthenticate() { // fetch posted credentials $email = \request::input('email'); $password = \request::input('password'); $remember = \request::has('_remember'); $credentials = [ 'email' => $email, 'password' => $password, 'confirmed' => 1 ]; // attempt log in user if (\auth::attempt($credentials, $remember)

given following table, network using 8-bit host addresses, asked compute associated range of destination host addresses every interface. asked number of addresses in every range. table: prefix match interface 00 0 010 1 011 2 10 2 11 3 i determined given prefixes of 8-bit binary ip's , concluded that: 00000000 00111111 (0-63 in decimal) uses interface 0 addresses in range = 2 power of (8 - number of bits in prefix, 2) = 64 01000000 01011111 (64-95 in decimal) uses interface 1 addresses in range = 2^(8-3) = 32 01100000 10111111 (96-191 in decimal) uses interface 2 addresses in range = 2^5 = 32 11000000 , higer (192+ in decimal) uses interface 3 addresses in range = 2^5 = 32 is reasoning correct? the number of addresses in each range 2 (8 - prefixlen) . if prefix has 2 bits, number of addresses 2 6 = 64.

using rsvp.js or other promises/a+ implementation how can turn code like... console.log('step 1'); settimeout(function() { console.log('step 2'); settimeout(function() { console.log('step 3'); }, 100); }, 300); into promises implementation? create delay function returns promise , resolves after specified time elapses in settimeout , this function delay(time) { return new rsvp.promise(function (resolve) { settimeout(resolve, time); }); } and can invoke this console.log("step 1"); delay(3000) .then(function () { console.log("step 2"); return delay(1000); }) .then(function () { console.log("step 3"); });

in unity game players able chop down trees using example axe. tree gets removed terrain , replaced falling tree prefab. works fine in small scale. looking more effective way though, because: the entire terrain needs reloaded if tree cut down. if terrain large , complex means entire game freezes few seconds whenever tree cut down. it works poorly in multiplayer. in order terrain stay in sync, players terrain needs reloaded each time tree cut down. means everyone's game freezes every few minutes. i have thought "chunking" terrain entire terrain built , don't know of way break parts after has been made. any ideas appreciated! i'm intermediate level programmer don't need write code me here, need idea or suggestion best way this?

i have altered slob.c gathers stats on last 100 small list allocations. made necessary edits make sure slob being used. i running test program calls malloc() 10,000 or 100,000 times on size of 20 bytes. but slob test results after test program runs states average claimed size 140 bytes (when expecting @ least somewhere near 20 bytes). what doing wrong, there way accurately test slob? i pretty sure stat collecting accurate, have had few professors check out me. current test program: int main() { char * ; int ; for( = 0; < 1000000; i++) { = (char*) malloc(20*sizeof(char)) ; if(a == null) printf("null\n") ; } //here print system call resulting stats memory claimed , free memory my original answer correct: char * ; int ; for( = 0; < 10000; i++) { = (char*) malloc(20*sizeof(char)) ; if(a == null) printf("null\n") ; } this simple code can used test how altered slob file allocates memory (co

eclipse tfs plugin says lot of files includes images (.png, vs..) have been edited although have made no change them when open "detect local changes" tab. understand files in bin/ folder supposed have been edited don't understand other files mentioned above seen edited tfs eclipse plugin. there idea of reason or solution it? when you're using server workspace, tfs treats file not have readonly bit set changed. that's how server workspaces work. if want tfs reflect contents of file need "undo unchanged", tfs automatically when check in (tfs never creates 2 revisions when both have exact same contents). or switch local workspace, in case tfs store copy of file in hidden folder, knows workspace version looked when tfs served you. tfs 2010 not support local workspaces. note tfs 2010 general support ends july 2015 , it's recommended upgrade tfs 2013u4 or tfs 2015 releases.

what timing iterations means ? @measurement(iterations = 50, time = 2) should time of measurement fixed, if iteration of measurement takes longer 2 seconds, iteration stopped ? if true impact have on measurements. the straightforward answer question is: "we have provide iteration time (or rely on default iteration time), because otherwise iteration never stop". depending on benchmark mode, meaning iteration time may different. example, javadoc says : /** * <p>throughput: operations per unit of time.</p> * * <p>runs continuously calling {@link benchmark} methods, * counting total throughput on worker threads. * mode time-based, , run until iteration * time expires.</p> */ throughput("thrpt", "throughput, ops/time"), there no way stop uncooperative execution in java, short of killing vm. (interrupting thread needs cooperation: there should check interruption). therefore, if @benchmark call takes longer re

i understand relation between marathon app , container. so, marathon app definition can contain single container definition (1:1)? far understand marathon rest api, link attached, answer yes. https://mesosphere.github.io/marathon/docs/rest-api.html#post-/v2/apps but supposed use app groups in order define such complex applications built more single container? have checked kubernetes, , idea of "pod" in case seems convenient build such applications, composed multiple containers, containers in same pod have single network stack, , application scaling happens on pod level. can say, kubernetes pod corresponds marathon app group? or should not try find similarities, rather should better understand marathon philosophy? thank you! regards, laszlo an app in marathon specifies how spawn tasks of application. while can specify how many tasks want spawn, every single on of these tasks corresponds 1 command or container. to you, need understand more use case.

i want calculate un-scaled absolute position of image drawn on canvas based on position clicked user on scaled canvas. i used following zoom implementation translate/scale bitmap within boundaries? so far, public boolean inme(int x, int y, region clickregion) { if(mscalefactor == 0) mscalefactor = 1; float curx = ((x*1.0f)/ mscalefactor) - (mposx * mscalefactor); float cury = ((y*1.0f) / mscalefactor) - (mposy * mscalefactor); x = (int)curx; y = (int)cury; //clickregion grapics.region computed on non-zoomed coordinates if (clickregion.contains(x, y)) return true; else return false; } this works fine, when there no zooming, when zoomed there significant issues. edit this algo used zooming , panning. public class panzoomview extends view { public static final string tag = panzoomview.class.getname(); private static fin

i in process of creating documentation c# code. i've done lot of ordinary source code , set doxygen create html out of it. arrived @ ui done in wpf, both xaml , source code. question is, best way document these files? comments possible in xaml not useful cannot nested. don't know if doxygen can possibly handle xaml documentation. should documented in xaml.cs files? i found more or less solution. @ first, have add file extension file_patterns , *.xaml in case. doxygen uses extension determine parser use. guess default c. next add documentation this: <!--> /** \file * \brief brief file description. * * more elaborated file description. */ --> the < !-- , --> comment section xaml files. when doxygen parses file removes documentation without adding it. that's why there > fool doxygen parser comment finished. know ugly worst can happen descriptions lost in documentation still available in files. long there no better way of doing stick this.

i using git in visual studio , getting error when trying pull: an error occurred. detailed message: 1 uncommitted change overwritten merge however when try , commit won't let me because have pull first, it's vicious cycle. there doesn't seem on how fix error within visual studio. how can latest version on server , overwrite local changes? how can latest version on server , overwrite local changes? in team explorer window, in list of pending changes (that’s create commits), can right click on files , click “undo…” undo whatever local changes did files. should able pull. however, shouldn’t need pull commit. git commits local repository, state of other remote repository never considered commits. there "out going commits", when "sync" gives me error. the “sync” button in “unsyched commits” view push , pull. indeed requires not have uncommitted changes (that overwritten) in working directory. go “changes” view , make com

a site of mine has strange behavior. time time of pages unpublished without user interaction. in page history there no entry activity. pages children of secured page. the unpublished pages not same. varies in page , in period. the apache access files give no information access outside. for testing changed content of these pages. after waiting few days 1 of these pages unpublished again. content of page did not change. can exclude possibility of nightly recovery of database provider. how can possible? system: silverstripe 3.1.12 (cms/framework) we can use onbeforeunpublish notify of when page unpublished debug problem. through sitetree extension. we declare sitetree extension in our config.yml file (or alternative yml file): sitetree: extensions: - sitetreeextension in extension class add onbeforeunpublish function email when ever page unpublished: class sitetreeextension extends dataextension { public function onbeforeunpublish() {
