[ Level One ] Watch mp4 video on Google Chrome on Ubuntu 12.04

When you install Google Chrome on Ubuntu 12.04, you might not watch mp4 video by Chrome, that's because you didn't install mpeg codec. (Ex. The online courses of Coursera) You could install ffmpeg-extra for chromium by apt-get command like below: 
$ sudo apt-get -y install chromium-codecs-ffmpeg-extra
$

Wish this helps.

[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
