ubuntu-14.04

I dont know how to install the latest Ruby on Ubuntu. First I installed the default Ruby 1.9.3, using sudo apt-get install ruby Then I tried to install the 2.0 version using sudo apt-get install ruby2.0 My version of Ruby is still "ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux])" What should I do? First of all, install the prerequisite libraries: sudo apt-get update sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev Then install

I understand that logstash now supports environment variables in config, as described here . But I can't seem to get it working when running logstash as a service. I am on ubuntu 14.04, logstash 1:2.3.3-1, and I launch logstash with sudo service logstash start . A final twist is that I am including logstash in a docker container, and I do NOT want to hardcode the variable value in my Dockerfile, I want it to ultimately be sourced from the command line when I launch the container, e.g. docker run -e ES_HOST='my_host' ...etc... . This is really the main reason I want to use environment variables

I've recently been setting up a new environment for a web application I'm working on and I've run into this following issue that I cannot figure out. Currently I have a docker-composer setup based off of https://hub.docker.com/r/ruslangetmansky/docker-apache-php/ Where I have my API, APP and DB running and need them to talk between each other. During the initialisation of this, I'm currently doing the following command: command: bash -c 'apt-get update && apt-get -y install curl libcurl3 libcurl3-dev php5-curl php5-oauth && rm -rf /var/lib/apt/lists/* && composer install && /sbin/entrypoint.sh

After running this code he save an infinite number of files with the source code of the first page(" http://site1.com "), why he doesn't go through other links and doesn't stop ? var args = ["http://site1.com", "http://site2.com", "http://site3.com"]; var fs = require('fs'); var i = 0; function handle_page(file){ page.open(file,function(){ page.evaluate(function(){ fs.write(i + '.html', page.content, 'w'); }); setTimeout(next_page,100); }); } function next_page(){ var file = args.shift(); if(!file){ phantom.exit(0); } i++ handle_page(file); } next_page(); page.evaluate() is the sandboxed page
