I'm building a simple recipe search engine with Ruby and Sinatra for an iPhone app, using RabbitMQ for my message queue. I'm looking around and finding a lot of different implementation choices for background processes, but most of them either implement custom message queue algorithms or operate as Rails plugins. What's out there in te...
Hey there, I've finally had a second to look into streaming, daemons, and cron tasks and all the neat gems built around them! But I'm not clear on how/when to use these things. I have a few questions: 1) If I wanted to have a website that stayed constantly updated, realtime, with my Facebook friends' activity feeds, up-to-the-minute ...
Using Daemons, how do I specify that my script's log goes in /log/ and its pid goes in /tmp/pids/? I've read the docs, and I see :dir/:dir_mode, but I can only make it do one or the other, not both -- seems like a really bad set of options if you ask me. ...

I have a problem handling DB connections in a daemon i've been working on, the first thing i do, is connect to my postgres db with: try: psycopg2.apilevel = '2.0' psycopg2.threadsafety = 3 cnx = psycopg2.connect( "host='192....
I have written a python script that checks a certain e-mail address and passes new e-mails to an external program. How can I get this script to execute 24/7, such as turning it into daemon or service in linux. Anyone that answers this, would I also need a loop that never ends in the program, or can it be done by just having the code re...

Hello there, I installed the ruby gem Daemons. To make sure it was working I created a script that would print to a file every 5 seconds. I then created another file to run the script using the trivial example they give you in the readme located at http://daemons.rubyforge.org/ . I require both rubygems and daemons. Then I type 'rub...
Hi all I've been trying to build a robust /etc/init.d/delayed_job script.

I am attempting to create a web-based game in Ruby on Rails. I have a model named 'Game', which has a datetime in the database entry that corresponds to a time that I would like the server to call the Game model's update_game function. Depending on the game's settings, this could be every 30 seconds to every 12 hours. Ruby on Rails ...
I need to build an internal service that queues the DB for changes (in one table) every one second, and processed data after this event. I do not need all the Rails stack since this service does not need the Controller/View functionality. Basically, from the rails stack, i only need AR (or an ORM). The found solutions/approaches for t...
I have a Ruby 1.9 script that I want to run as a long-running background process. It looks like I have a choice between calling Process.daemon inside the script to daemonize it, or I can just run the script in the background using a shell's ampersand and keep it running after I log out of the server by prefixing the command with nohup....

Clarification: 1) By Monitoring I mean "knowing current running state, memory usage, process usage ". 2) Would prefer very little setup requirements imposed. Assumpt...
I'm currently porting a Rails App currently using REE to JRuby so I can offer an easy-to-install JRuby alternative. I've bundled the app into a WAR file using Bundler which I'm currently deploying to GlassFish. However, this app has a couple of daemon processes and it would be ideal if these could be part of the WAR file, and potentiall...

Hello. Can't find out if daemon application can be run on non-jailbroken iPhone. And what is Apple policy about this stuff? I don't really know if my idea is possible at all... I wonder if it's possible to create such a daemon that can intercept outcoming user call and play custom tone signal while remote user does not answer our call. A...
