There's some secret that you should know before you make time scaling in ruby on rails specially to the view. I have little smile when seeing helper from a developer that make time helper like in twitter or facebook, example a moment ago, or 3 minutes ago, or 1 hour ago. Why you hurt your brain if Rails already supports it. I think that he doesnt know the secret, now let me tell you the secret:

distance_of_time_in_words_to_now
Reports the approximate distance in time between from Time to time now. Set include_seconds to true if you want more detailed approximations when distance less than 1 min.  example :

<%=  distance_of_time_in_words_to_now(from_time, include_seconds =  false) %> 

<%=  distance_of_time_in_words_to_now(from_time, to_time = 0, include_seconds = false, options = {}) %>

0  - 29 secs # => less than a minute
30 secs to 1 min, 29 secs # => 1 minute
1 min, 30 secs to; 44 mins, 29 secs # => [2..44] minutes
44 mins, 30 secs to 89 mins, 29 secs # => about 1 hour
89 mins, 29 secs to 23 hrs, 59 mins, 29 secs # => about [2..24] hours
23 hrs, 59 mins, 29 secs to 47 hrs, 59 mins, 29 secs # => 1 day
47 hrs, 59 mins, 29 secs to 29 days, 23 hrs, 59 mins, 29 secs # => [2..29] days
29 days, 23 hrs, 59 mins, 30 secs to 59 days, 23 hrs, 59 mins, 29 secs # => about 1 month
59 days, 23 hrs, 59 mins, 30 secs to 1 yr minus 1 sec # => [2..12] months
1 yr to 1 yr, 3 months # => about 1 year
1 yr, 3 months to 1 yr, 9 months # => over 1 year
1 yr, 9 months to 2 yr minus 1 sec # => almost 2 years
2 yrs to max time or date # => (same rules as 1 yr)

Rainbows! is an HTTP server for sleepy Rack applications. It is based on Unicorn, but designed to handle applications that expect long request/response times and/or slow clients. For Rack applications not heavily bound by slow external network dependencies, consider Unicorn instead as it simpler and easier to debug.

Rainbows is mainly designed for the odd things Unicorn sucks at:

• Web Sockets (via Sunshowers)
  
• 3rd-party APIs (to services outside your control/LAN)
  
• OpenID consumers (to providers outside your control/LAN)
  
• Reverse proxy implementations with editing/censoring (to upstreams outside your control/LAN)
  
• Comet
  
• BOSH (with slow clients)
  
• HTTP server push
  
• Long polling
  
• Reverse AJAX
  
• real-time upload processing (via upr)
  Rainbows can also be used to service slow clients directly even with fast applications.

A moment ago i have a problem about how to get Home Line or status from a group users list in my Air Application and sort them by date ascending. My analyst is if an account has 20 tweets but the group has 10 users, it means that i have to sort 200 list. Why don't use SortOn for Array? If you try myArray.SortOn("date",[Array.CASE_SENSITIVE, Array.UNIQUE ]), it can't sort date (string type in twitter) very well, we have to convert them from string to millisecond, and it will take time, maybe crashed.

My idea is, unite them in a list in customer twitter account then get the list status, make sense, no ? For this case i use library from Sandro (Thanks Dude) , which is named tweetr, badly no more example about create list like my case. When i read the documentation, it seems simple, but the process is not like that. The list status, only can pull status of users which are public, so if it is protected you can't pull them.

Here is the sample of my work, you can try by clicking the demo link below (this sample not stores your twitter login ^_^), the demo is in flex version, but you can convert it to Air easily.

DEMO
SOURCE (Flex)

1. Debugging Console : Use the collapsible console to quickly view output from your RhoSync source adapters.
2. File Manager : Navigate and modify your app's files in a simple view.
3. Rich Editor : Use the powerful Ruby/HTML/CSS/Javascript editor right from your browser, or work locally and upload your app.
4. Text Search :  Search for text in all files of your app.
5. Toolbar & Quick Links :  Access all of RhoHub's productivity tools right from the editor.

Edit Client Code

From the Client tab you can see all components of your app that are used to generate the app running on the device. RhoHub provides a fully functional CRUD (create, read, update, delete) UI for your app. This is a set of Rhodes framework views (HTML templates) and a Ruby based controller. But you will likely want to customize the interface further. You can now edit the HTML/CSS/Javascript interface, or the Ruby controller code (controller.rb) that has your app's business logic.

Edit Server Code

From the Server tab, you can also edit the backend source adapter to add synchronized data to your app. A copy of the RhoSync server on RhoHub will then execute your source adapter. Note that this step is not actually required. Before you test the source adapter (by clicking Show Records) you will want to subscribe a user to the app. A link is provided to remind you to do that if necessary. By clicking on Show Records, the RhoHub-provided RhoSync server will execute the query method of your source adapter. If there are errors with your source adapter, they will be displayed in a console above the editor.

Build For Your Device

From the build screen you can choose your target smartphone OS and RhoHub will run a build job for you. Generally builds take about a minute to complete. By downloading one of the simulators that we provide links to you can test your smartphone app locally by downloading the build. If you want to accelerate the time to see the results of your code, you can download the Rhodes desktop simulator if you are running Windows or Mac OSX. From the desktop simulator you can then use the "Refresh Bundle" option to instantly test code changes made in the RhoHub IDE.
