[Level 1] How to install Scala on Ubuntu.

You have two way to install it.
1. Use apt-get:
# sudo apt-get -y install scala
2. Download source: (browse http://www.scala-lang.org/downloads first)
# cd /opt
# wget http://www.scala-lang.org/downloads/distrib/files/scala-2.9.0.1.tgz
# tar -C /opt zxf ./scala-2.9.0.1.tgz
# export PATH=$PATH:/opt/scala-2.9.0.1/bin
# scala -version
Wish this helps.

[Level 2] Shell Interactive With Zenity Episode 5 -- list

Image
If you want to give a list for user to choose, you can use the option "--list". The command synopsis as below: SYNOPSIS      zenity  --list [--title=title] [--window-icon=path] [--width=width]    [--height=height] [--timeout=seconds] [--column=text] [--checklist]       [--radiolist] [--separator=character] [--multiple] [--editable] [--print-column=number] [--hide-column=number] Just like " --calendar ", if you press "ESC" key or click button "Cancel", the return code will be "1". If you select one option and click "OK", zenity will response the option and return the code will be "0".

[Level 2] iif in Python

If you want to implement iif in Python, please refer to the following sample code: #!/bin/env python def iif(b): return 'It\'s True' if b else 'It\'s False' print iif(True) print iif(False) And the following sample, guess what will you get! #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % 'Ture' if b else 'False' Result: $ ./iif.py b: Ture False The second result is "False", not "b: False". Why??? Because the prededence of string concatenation is higher than if. Therefore you need to use () to make it correct. #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % ('Ture' if b else 'False') Wish this helps. regards, Stanley Huang
