[Level 1] Remote UI display in local Ubuntu X.

If you want to display remote UI to your local X.
You can use ssh -X to login remote server.
Ex.
local# ssh -X user@remote_host
remote# echo $DISPLAY
local_host:10.0
remote# xclock
Then you can see xclock on your local X

Wish this helps.

[Level 1] Reversion of git

Just read an article mentioned about the reversions of git, so take a note here.

[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
