i'm making quiz app. user has finish phrase shown on display , write name of car in edittext, after pushing on button, if answer right, edittext become green, if doesn't, become red. if answers right (green), intent move on next activity. the question is: how optimize code, don't how it's like? if decide add more options wouldn't readable. public class mainactivity extends appcompatactivity { edittext et_one_one, et_one_two, et_one_three; button buttoncheck; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); et_one_one = (edittext) findviewbyid(r.id.et_one_one); et_one_two = (edittext) findviewbyid(r.id.et_one_two); et_one_three = (edittext) findviewbyid(r.id.et_one_three); buttoncheck = (button) findviewbyid(r.id.buttoncheck); buttoncheck.setonclicklistener(new view.onclicklistener() { @override public void onclick(view v

i have been building mvc 5 month now. before deep in project want make sure security done , build secure web site. have created 5 pages should available , implement aspnet.idenity. first wanted test following works expected. expecting pages fail security reasons except home page. based on research if add: public static void registerglobalfilters(globalfiltercollection filters) { filters.add(new handleerrorattribute()); filters.add(new system.web.mvc.authorizeattribute()); filters.add(new requirehttpsattribute()); } every page should require https , logged in user. decorated home, index controller [allowanonymous] can land on 1 page when start project. expecting every other page fail, or error or redirect login (not sure how since not https yet). but every page works no problems. should able test using localhost, or need server environment iis? understand that possibility http, think authorizeatribute should tested , fail. not doing right? yes. but auth

i want able save name , path of recorded audio file, these values next time start app. believe can save them this, local storage: // after recording done function capturesuccess(mediafile) { addfilepath(mediafile); } function addfilepath(mediafile) { localstorage.setitem(mediafile.name, mediafile.fullpath); } how can these values next time start app? there better way store these values? in way, when try path of audio file next time can not know key 'mediafile.name'. in application, created object contains file's informations, stored in localstorage using constant key 'audio'. following example illustrates how that: var filename = "audiofilename"; var filepath = "audiofilepath"; localstorage.myaudio = { name: filename, path: filepath }; // file's informations in next time var audio = localstorage.myaudio; var filename = audio.name; var filepath = audio.path; if want store more 1 file : // stored array in loc

i have mocha tests need re-lift sails different configuration mocks policies using moduleloaderoverride. in general, working, seems sails not lowering , re-lifting properly. the utility file management of sails instance tests: // util var sails = require('sails/lib/app'), sails; module.exports = { sailsinstance: undefined, testconfigs: {}, start: function(callback) { this.sailsinstance = new sails(); /* config not enforced remaining tests, quick lift our code can use sails config parser , extract other configs easily. */ this.sailsinstance.lift({}, function(err, server) { sails = server; // populate this.testconfigs object here this.configuresails('defaultconfig', callback); }.bind(this)); }, end: function(callback) { this.sailsinstance.lower(callback); }, configuresails: function(configname, callback) { console.log('lifting with:', configname); var launchconf

there c++ code looked in tutorial video (line numbers added clarity): 1. config defaultconfig("/etc/foobar/config"); 2. config userconfig("~/.config/foobar/config"); 3. config conf; 4. /* else not involving `conf` */ 5. conf = defaultconfig.join(userconfig); my question is, how many instances of config class being created? in case, join function returns new config instance, rather modifying existing one, @ least 3 objects being created. my question third line ( config conf; ). c++ automatically create config instance on line (even though in other language, such java, have manually tell assign new config() )? or c++ compiler smart enough realize conf object never accessed, instead gets replaced on line #5? how memory allocated? enough 3 references , 4 config instances, or there more going on behind scenes? c++ isn't java, there no references here, class objects. say, there 3+1 objects created code. you can delay creation of t

in application need use piece of software able to: a) convert words basic forms , b) find if 'nouns', 'verbs' etc. i found list of software able job. http://aclweb.org/aclwiki/index.php?title=morphology_software_for_english does have experience of these? 1 recommend? you can use nltk (python) perform these tasks. find if 'nouns', 'verbs'... this task called part-of-speech tagging . can use nltk.pos_tag function. (see peen treebank tagset ) convert words basic forms this task called lemmatization . can use nltk.stem.wordnet.wordnetlemmatizer.lemmatize function. example import nltk nltk.stem.wordnet import wordnetlemmatizer nltk.corpus import wordnet wn penn_to_wn = lambda penn_tag: {'nn':wn.noun,'jj':wn.adj,'vb':wn.verb,'rb':wn.adv}.get(penn_tag[:2], wn.noun) sentence = "the rabbits eating in garden." tokens = nltk.word_tokenize(sentence) pos_tags = nltk.pos_tag(tokens)

catberry has requirement components – ids must unique. what's best practice building unique ids when have complicated hierarchy of nested components? the recommended way building unique identifiers nested components is: <parent-component­-id>:<child-component­-name>:<entity-­id>. entity-id optional , used in case have list of items or that. it’s easy have id of component in render method using this.$context.attributes.id . for example, have component renders list of items. name cat-list id some-list . nested components name cat-list-item have ids: some-list:list-item:1 some-list:list-item:2 some-list:list-item:3 ... some-list:list-item:n if have more nested components cat-author each item have ids: some-list:list-item:1:author some-list:list-item:2:author ... some-list:list-item:n:author so, if use rule have unique identifiers components on page.

i'm trying package project using optaplanner 6.0.1 libraries .jar through intellij idea's jar artifact instead of manifest.mf containing standard manifest-version: 1.0 main-class: a.b.c.app the jar uses 1 supplied in ecj-3.7.2.jar, 1 of optaplanner's supporting libraries: manifest-version: 1.0 build-jdk: 1.6.0_26 built-by: ibrandt created-by: apache maven archiver-version: plexus archiver because of this, "no main manifest attribute, in appname.jar" error happens when trying run app. if manually replace manifest in .jar file mine works correctly. there can fix this? i keep libraries in separate /lib directory , added root of jar artifact extracted directory, intellij idea v13.0.1. i had same problem. make sure manifest.mf in: src/main/resources/meta_inf/ not src/main/java/meta_inf/

i have game controller (e.g. wii) gives me in software position , orientation. the given spatial data has lot of noise, both because of hardware, , because user human, , human hands aren't stable. i want implement similar gimbal, stabilize input , remove noise. ideally, if hand held in place, spatial data should stay same, if in reality hand moves little bit. , when hand moving, data should stable , smooth, , not jiggly , noisy. i tried simple things moving average, it's not effective actual gimbal. searching related "gimbal" either results in game rotation math (gimbal lock), or electronics projects use physical gimbal. are there resources related stabilizing spatial data?
