Mind Blowing Facts

first off, i'd apologise if has been covered. it's difficult filter through existing issues similar one. so in windows there 2 (as far i'm aware) ways set environment variables. first 1 through command prompt , second through system properties in control panel. the former more desirable me have issue variable lasts , exists in session. gets considerably annoying when have re-set java path every time. the latter have resort to, takes time , once in blue moon i'll forget locate menu. is there have in command prompt set permanently? possibly flag or switch append command? the setx command can modify environment variables persistently: setx provides command-line or programmatic way directly , permanently set system environment values. it's quite powerful tool read notes on page though because there few little catches using it.

i have folder path following: /h/apps/new/app/k1999 i want remove /app/k1999 part following regular expression: set folder "/h/apps/new/app/k1999" regsub {\/app.+$} $folder "" new_folder but result /h : many elements being removed. i noticed should use non-greedy matching, change code to: regsub {\/app.+?$} $folder "" new_folder but result still /h . what's wrong above code? non-greedy means try match least amount of characters , increase amount if whole regex didn't match. opposite - greedy - means try match characters can , reduce amount if whole regex didn't match. $ in regex means end of string. therefore something.+$ , something.+?$ equivalent, 1 more retries before matches. in case /app.+ matched /apps , first occurrence of /app in string. can fix being more explicit , adding / follows /app : regsub {/app/.+$} $folder "" new_folder

for android app need determine when user increases speed , when decreases it, don't need find exact speed value, know if has increased, decreased or it's same. first solution came register listener gps , in onlocationchanged() method calculate speed , check see if greater or equal, didn't worked, beacuase speed inaccurate. solution tried use accelerometer measure steps in 2 seconds, , compare measure previous one, see greater, didn't found exact algorithm. found approximation android pedometer github code sample: https://github.com/bagilevi/android-pedometer , wasn't accurate. so, solution should use? what's effective way of counting steps accelerometer? thank you.

first have master branch in remote repo on internet. , know if changed local files, how update local changes remote repo. problem is, if don't want new changes in local tracked files, how return using updating remote repo in github? i have tried following things: i use git checkout origin master to master repo. i make sure 1 tracked file, named main_32.f90 changed little bit in comment line. then use git pull it turns out date. already up-to-date. i checked main_32.f90, not original 1 changed 1 in comment line. means git pull not working. so how it? if don't want keep local changes, can hard reset pointer, branch, sha1, etc discard changes. git reset --hard head . use this kind of aliases have pretty view of working tree if console fan , don't want use gui suggested other users.

i want use objective-c nullability feature. should annotate nullable/nonnull implementation file or interface? the reason declare nullability have warning feedbacks compiler unit (see https://developer.apple.com/swift/blog/?id=25 ). as best practice, should set nullable , nonnull (or _nullable , _nonnull) in declarations. so should interfaces, depending on coding standards, may implement class-scoped (or category-scoped) methods without declaring them, , in case declaration implementation , should declare nullability values. you can declare nullability implementations declared in interfaces, in opinion degrades maintainability.

having trouble correctly looping through vector of unique_ptrs own custom object. i've provided pseudo-code below isn't fleshed out, focus on loop. i'd use c++11 "for" loop, , iterate on vectors - or i've heard, providing own iterators better? don't know how when have separate classes. if i'm keeping vector in manager class, should define iterator methods? in object class, or manager class? want make sure data stays const, actual values aren't able changed. // class our data class geosourcefile { // data, doesn't matter double m_dnumber; int m_nmyint; } // singleton manager class class gsfmanager { public: // gets pointer vector of pointers geosourcefile objects const std::vector<std::unique_ptr<geosourcefile>>* getfiles( ); private: // vector of smart pointers geosourcefile objects std::vector<std::unique_ptr<geosourcefile>> m_vgeosourcefiles; } void app::ondrawevent {

i using angular js , trying catch errors in pages, problem not catch errors in pages, example doing referenceerror in 1 of controllers , not catch this. $rootscope.$on("$statechangestart", function() { window.onerror = function( msg, url, line, col, error ) { var = !col ? '' : '\ncolumn: ' + col; += !error ? '' : '\nerror: ' + error; var data = { msg : msg, url : url, line: line + } alert('error'); var suppresserroralert = true; return suppresserroralert; }; } how can make work? don't use window.onerror, instead use $exceptionhandler. angular has global $exceptionhandler factory catches errors happen inside controllers, services, etc. any uncaught exception in angular expressions delegated service. angular.module('exceptionoverride', []).factory('$exceptionhandler', function() { return function(exception, ca

so have: class mysuperbehavior extends marionette.behavior bunch of classes extends marionette.itemview , uses mysuperbehavior , tralalaview , trololoview etc i want create method mysuperbehavior every instance of tralalaview , trololoview can use. how can correctly? sample code illustrate: var mysuperbehavior = marionette.behavior.extend({ awesomenonstaticmethod: function(){ console.log(this); } }); we suppose correct linking of classes var tralalaview = marionette.itemview.extend({ behaviors: { somebehavior: { behaviorclass: mysuperbehavior } } // methods here }); var instoftralala = new tralalaview(); console.log(instoftralala.awesomenonstaticmethod()); // want i did that: var mysuperbehavior = marionette.behavior.extend({ initialize: function(options, view){ this.view.awesomenonstaticmethod = this.awesomenonstaticmethod } awesomenonstaticmethod: fu

consider list l like: l<-list(a=24,b=12,c=30,d=1) how sorted version on values of such list, preserving names? in result list order of elements should then: d , b , a , c corresponding sequence 1,12,24,30. you can use order . assuming length of each list element 1 showed in example l[order(unlist(l))]

i python newbie might sound silly question, have csv file , want script print number of lines , number of columns in file. script: import csv op = open(test06242015.csv) rd = csv.reader(op) row in rd: list = [] list.append(row) print list items in row: print len(row) op.close() i getting right answer (320), prints out 320 times each row (below): [['19.385', '19.227', '18.308', ...]] 320 320 320 320 320 320 320 320 (...and keeps going) how can make 320 prints out once? also, how can read number of rows well? thanks lot! you printing length of row inside inner loop, try printing outside inner loop. example - for row in rd: list = [] list.append(row) print list items in row: pass # or whatever other logic want, if not want remove loop print len(row)

i have array of positive integers. how display image? not range of values array contains or size of array. similar question asked here . not know possible values without searching possibly large array. best way of doing regards efficiency , length of code? here small example of data be 0 2 4 6 8 10 12 14 16 2 2 6 6 10 10 14 14 18 4 6 4 6 12 14 12 14 20 6 6 6 6 14 14 14 14 22 8 10 12 14 8 10 12 14 24 10 10 14 14 10 10 14 14 26 12 14 12 14 12 14 12 14 28 14 14 14 14 14 14 14 14 30 16 18 20 22 24 26 28 30 16 18 18 22 22 26 26 30 30 18 take here . int xlenght = arr.length; int ylength = arr[0].length; bufferedimage b = new bufferedimage(xlenght, ylength, 3); for(int x = 0; x < xlenght; x++) { for(int y = 0; y < ylength; y++) { int rgb = (int)arr[x][y]<<16 | (int)arr[x][y] << 8 | (int)arr[x][y] b.

if have device 3 wireless interfaces 1) zigbee 2) gsm , 3) bluetooth. is there limitations transport protocol use protocols mqtt, coap, xmpp? can use coap on zigbee , gsm example? , mqtt on bluetooth , gsm? i understand each interface has different power requirements protocol have power requirement also? assume device battery powered. thanks the same problem troubles me. want know if mqtt can work on bluetooth or wifi-direct on android. according iot tiny devices: let's talk mqtt-sn , mqtt-sn designed support non-tcp/ip based protocol zigbee or bluetooth(not sure), , coap needs ip protocol. hope you.
