i have rails application displays active events (events on or after today). scope :active, where("event_date >= ?", date.today).order("event_date asc") it coming fine on local. on production server , query taking date of deployment comparison. this log select "events".* "events" "events"."school_id" = 32 , (roster_id in (45) or roster_id null) , (event_date >= '2014-09-18') order event_date asc but if check console on production, showing correctly 1.9.3-p448 :001 > date.today => fri, 19 sep 2014 server on aws ec2 any appreciated. try putting in lambda: scope :active, -> { where("event_date >= ?", date.today).order("event_date asc") } probably date.today being evaluated @ time when code loaded(i.e. deployed).

i'm new angularjs , i've created simple input box want default value. here's input: <input id="fieldwidth" min="10" type="number" value="10" ng-model="set.width"> however, value doesn't show default. when try set though scope in controller $scope.set.width = "10"; it says "cannot set property 'width' of undefined" what missing? if haven't already... should set $scope.set before trying set it's child: $scope.set = {width:10}; or $scope.set = {}; $scope.set.width = 10; or can without set object if don't have other values associating it. $scope.width = 10; <input id="fieldwidth" min="10" type="number" ng-model="width">

is possible tell nuget want use latest version of package with particular major version , never above major version? for instance, let's take example jquery: can't use 2.x version if need support of old browsers. we're limited use latest 1.x version. we know available (and offered default in manage nuget packages dialog) version of jquery 2.1.1. rather using version, need use latest major version of jquery 1.x branch, currently, 1.11.1. i know how install 1.11.1 version. 1 simple solution manually edit packages.config file replace value of version attribute 1.11.1 : <packages> <package id="jquery" version="1.11.1" targetframework="net451" /> </packages> and build project. what don't know how tell nuget keep track of releasing new versions of 1.x branch offer me updating them same way when new 2.x version released: by default, nuget try update latest 2.x version, not latest 1.x. in other words, wh

i'm building class want configure using various parameters may 1 of: int , double , string (or const char * matter). in language ruby, build initialization function takes hash keyed string. example: class example def init_with_params params puts params end end e = example.new e.init_with_params({ "outputfile" => "/tmp/out.txt", "capturefps" => 25.0, "retrydelayseconds" => 5 }) how can create similar behavior in c++? looking around found several posts talking boost::variant . rather avoid using boost if limiting different types 3 types mentioned above rather clean solution can made. edit : agree using designed , tested code such boost.variant better re-implementing same idea. in case, problem reduced using 3 basic types, looking simplest possible way of implementing it. here cut down version of regularly use store program configuration properties, maybe find useful: #include <map> #include <

i have requirement communicate custom bluetooth le device. communication needs be secure (plain text cannot read) not vulnerable replay attacks contained within 20 or 22 bytes per message bluetooth le restrictions (or phone api implementation restrictions) trusting bluetooth le's native encryption alone seems poor choice based on this: https://github.com/mikeryan/crackle/ so come implementing our own encryption. in normal client / server communication (tcp example) no message size restriction, aes-128 in cbc mode pre-shared private key might choice. however bluetooth le there's not enough space transmit initialization vector each characteristic read / write it seems error prone keep track of changing ivs based on last block of last message received / transmitted, given multiple characteristics being broadcast etc. have missed other way of making bluetooth le secure? ...fragment data 20 bytes , multiple write ble characteristic stored in gatt. n
