i have class (cars) has int id instance variable. the id not have unique - more of category id. if id exists add object array list within category if id not exist create new category id before create instance of class want check there isn't instance variable id. the way can think of doing right having static arraylist of cars within class cars. search through array list through each car , compare ids see if there id matches. if not - create the new car instance new id. surely there better way of doing this? using map, suggested lutz horn, better way of holding ids, , hashmap in runtime complexity of o(1), rather searching elements of container such list. if cars might concurrently created using several threads, should, of course, make sure not enter race condition.

i'm developing ionic/cordova app. there textarea visible user can input data, transferred server. here, user should able input line breaks. problem i'm facing right it's possible after input first character; , it's not possible begin line break. ng-model cuts off beginning line breaks. how can achieve goal? the textarea looks this: <textarea ng-model="card.text" id="text-message" rows="20"></textarea> thank you. according https://github.com/angular/angular.js/issues/2010 can apply ng-trim="false" element stop behaviour so: <textarea ng-model="card.text" ng-trim="false" id="text-message" rows="20"></textarea>

on windows pc have latest version of node 6.9.1 has v8 inspector built in. when use --inspect flag run app.js file , go "chrome-devtools" url attach debugger, works fine (i can set breakpoints , step through code) console.log code doesn't print chrome console. checked console filter, set all. prints console window ran app, not chrome. i have windows server 2008 r2. dont have issue on macbook, logs chrome console fine. hoping check if have working on windows computer or if else has run issue. maybe server 2008 r2 issue? it easy test. create app.js file 1 line "console.log('test')", open command prompt or git bash or whatever in folder , type: node --inspect --debug-brk app.js it give chrome-devtools url. go url in chrome , see app. script execution stopped (due -brk flag) have resume it. if have same issue me, notice when resume it, nothing logged console.

all! i'm configuring exim mail-server , i'm newbie it. not first mail server configuration, first of exim. so far, have read different config docs (e.g. this one ) in internet , exim's configuration manual, well. , more clear me. 1 issue not clear yet - concerned .ifdef, .ifndef directives. example, .ifdef check_mail_helo_issued deny message = no helo given before mail command condition = ${if def:sender_helo_name {no}{yes}} .endif far saw manual , clause means if macros check_mail_helo_issued declared, followed actions applied. if not present anywhere, actions not applied. , if want apply acl (it part of acl), better use without .ifdef directive. so, please, correct me if i'm wrong, you either delete .ifdef , .endif directives or define check_mail_helo_issued = yes somwhere logically 'before' deny statement.

we have 2 solr environments in production. 1 solr environment has latest 2 years data. other has last 10 years of archived data. @ moment, these 2 solr environments connect separate zookeeper ensembles. the collections have same name & configuration in both solr environments. want reduce number of servers zookeeper. is feasible have both solr environments in production connect 1 zookeeper ensemble without overwriting configs each other? or mandatory have separate zookeeper ensemble each solr environment? you can use same zookeeper ensemble handle more 1 solr or solrcloud instance. however, data must kept separate. (probably) best done using "chroot" functionality in zookeeper. essentially, when create "space" in zookeeper solr instance, append /some_thing_unique , keep in appropriate config files in solr - should have no trouble. i haven't experienced moving existing solr instance 1 zookeeper - i'd guess have take solr down, ch
