Cruise:Onboard Twitter/StatusNet

From JoCopedia
Jump to: navigation, search

StatusNet is an Open Source project to create a Twitter like service. There is a fan initiative to investigate it's suitability for onboard communication.

Proof of Concept

There is a proof of concept server located at Access is by web, iPhone app, Android app, or desktop app. Mobile clients should use as the server.


A list of known issues with the current proof of concept server.

  • Error reported during account creation
    • Likely due to incorrect configuration of sendmail
    • Should just disable email validation
      • After looking at the registration code, sending emails is not configurable. Source needs modification to allow for this. Should be pretty easy to do.
  • As of July 2010, native Twitter app doesn't work with StatusNet. Authentication in the app is hardcoded to official Twitter site.
  • (may 3, 2011): After twiddling with the configs, iPhone app clients crash. Will investigate.
  • (may 3, 2011): Looks like the iPhone app is no longer available on the App Store. StatusNet says a new client is being added.


  • Disable attachments
    • Doable with configuration $config['attachments']['supported'] = false;, but still see the attachment icon, and receive the misleading error message like "image/png" is not a supported file type on this server. Try using another image format."
    • Probably only possible to remove icon with CSS
  • Disable location services
    • We're gonna be on a boat.
    • Done. Need to set the following in the config:

$config['location']['sharedefault'] = false; # sets default to false
$config['location']['share'] = false; # disables user's ability to change default

  • Disable OpenID
    • Done, need to unload the OpenID plugin with the following in the config:


  • Install PHP bytecode accelerator
    • APC appears to be the defacto standard
  • Disable URL shorteners
    • Done by unloading the shorteners:


    • Look into disabling URLs


The current proof of concept server is running under a free Amazon EC2 micro instance. Available RAM is 79MB of 613MB. During the current light testing, CPU usage has not exceeded 15%. Likely need 1 GB and a low end processor for real hardware. A small, cheap netbook is almost certainly likely to handle the load.
