YASCal - beta release

Sat, 12 May 2012 02:12:08 GMT

Jerry Seinfeld invented a unique system he used to motivate himself to write. He put a big wall calendar on a prominent place. For each day he did his task of writing, he put a big red X over that day. Read more about this at: lifehacker

Then, as he explained:

after a few days you’ll have a chain. Just keep at it and the chain will grow longer every day. You’ll like seeing that chain, especially when you get a few weeks under your belt. Your only job next is to not break the chain.

You can use YASCal to manage different ‘Seinfeld Calendars’ for your personal goals, whether these are to get you back in shape, learning something new, finishing things or simply forming good habits. Good luck!

extra 5 minutes of fun; JRuby and Velocity

As promised, this time I am showing you a very simple way to play with Velocity templating language in JRuby.

jvel.rb

# A simple JRuby Velocity integration demo 
# Notes: 
# - save this script as 'jvel.rb'.
# - in the folder from where you're executing this simple script, you'll
#  have a subfolder: 'lib', containing the Velocity library:
#   lib/velocity-1.6.2-dep.jar
# This jar is intended to be used when you do standalone development
# with Velocity. And assuming that you have jruby in the path, you can 
# run the script:
#
#   $ jruby jvel.rb World
#
# You'll see: Hello World!
# ----------- 

require 'java'   

Dir["lib/*.jar"].each { |jar| require jar }
 
class JRubyVelocity   
    include_class 'java.io.StringWriter'   
    include_class 'org.apache.velocity.app.Velocity'   
    include_class 'org.apache.velocity.VelocityContext'    

  def render ( arg) 
    Velocity.init
    writer = StringWriter.new  
    ctx = VelocityContext.new( {'name' => arg})                      
    Velocity.evaluate( ctx, writer, "log", "Hello ${name}!") 
    return writer.getBuffer
  end
end  

puts JRubyVelocity.new().render( ARGV.pop)

Good luck!
