script/console -- the rails irb   14 Nov 05
[print link all ]
Few rails users know that script/console exists. It lets you interactively explore your rails application. It is quiet similar to irb.

It can help to avoid a lot of browser reloads and so ultimately speed up developmpent even further. It’s a great debugging tool, and it’s fun to play with your objects in real time. But even better; you can use it to get work done. You have full access to your models.

 >> u=User.find_by_username('m94asr')
 => #<User:0x23b34b0 @attributes={"username"=>"m94asr",
   "firstname"=>"Armin", "id"=>"1", "surname"=>"Roehrl", "password"=>"XX"}>

 #reload your code
 load 'sample.rb'
 sample.do_sth

Start the console with the console script:

 ruby script/console

If you start it without arguments the script will start the console in the development environment. To get to the production DB type

 ruby script/console production

I came by accident across this interesting study by ScottBarron.

The Ruby on Rails application framework provides several options for storing session data. Each option has its advantages and disadvantages which may not be readily apparent. The tests outlined in this document attempt to lay some groundwork which should help when determining which storage container is most suitable for your application.

I highly recommend reading it!

Getting your RSS feed into google/ig   12 Nov 05

I like Google’s new personalized startpage. Adding your own data feeds via RSS is very simple.

Simply click on the top-left on Add Content.

Then click on "Create a Section" and add the right feed. For this blog:

 http://www.approximity.com/cgi-bin/blogtariAgile/index.rb/synopsis.rss

and for Futurometer:

 http://www.futurometer.com:3001/rss.xml

Now it will show up. Thanks to Ajax you can move the sections around with the mouse. Enjoy it!

Adium: instant messaging   12 Nov 05
[print link all ]
Adium is a free instant messaging application for Mac OS X that can connect to AIM, MSN, Jabber, Yahoo, and more

After some searching and experimentation I recommend Adium on os X. On Linux I prefer gaim. Adium uses libgaim.
