i saw blog jxcore can create executable based on js code (to run command line application) , protect source code being seen easily. but when tried following, saw excutable file (in ubuntu) still contains source # jx package test1.js # change library , extract attribute in file test1.jxp false # jx compile test1.jxp # grep "this test1" test1 binary file test1 matches the little js file test1.js console.log("this test1"); i understand there no perfect way of protecting application being reversed. hoped there no simple way (like "strings" command) grab source code out of executable. the blog post read is, put, outdated , wrong. the "protection" features provided jxcore severely flawed , , largely removed in later releases of project. do not use jxcore. development on project halted in march 2016 ; has fallen behind node.js platform, , provides no real benefits on open solutions pkg .

so have directive 21 inputs in it. want set ng-modelbased on attribute passed when calling directive. if {{myattr}} inside directive outputs attribute i've set, if include ng-model="{{myattr}}" things break. angular.module('myapp') .directive('program', function () { return { templateurl: 'app/program/program.html', restrict: 'ea', link: function (scope, element, attrs) { scope.daymodel = 'program.' + attrs.day + 'first'; } }; }); you use {{variablename}} in pure html-text, angularjs can replace value of variable @ runtime: http://jsfiddle.net/joshdmiller/hb7lu/ but never write ng-form="{{myattr}}" in html-tag, instead have write ng-form="myattr" {{}} serves way angularjs distinguish between plain text , variable/code. in html-tags there no plain text, instead interpreted variable/code.

as people painfully aware of now, java api handling calendar dates (specifically classes java.util.date , java.util.calendar ) terrible mess. off top of head: date mutable date represents timestamp, not date no easy way convert between date components (day, month, year...) , date calendar clunky use, , tries combine different calendar systems 1 class this post sums quite well, , jsr-310 expains these problems. now question is: how did these classes make java sdk? of these problems seem obvious (especially date being mutable) , should have been easy avoid. how did happen? time pressure? or problems obvious in retrospect only? i realize not strictly programming question, i'd find interesting understand how api design go wrong. after all, mistakes learning opportunity (and i'm curious). someone put better ever it: class date represents specific instant in time, millisecond precision. design of class bad joke - sobering example of how p...
