[Level 1] How to setup Cassandra home directory

If you want to create multi Cassandra instances and only use one copy of binary.
You need to setup CASSANDRA_HOME environment variable.
If you only use symbolic link to link binary file,
Cassandra will search the real binary directory and set its parent directory as the home,
if you don't setup the CASSANDRA_HOME environment variable.
# export CASSANDRA_HOME=[new directory you want]
# cd [new directory you want]
# ./bin/cassandra
Wish this helps.

[Level 1] Rar tool for Solaris.

Sometimes we will got a rar compressed file from our friends, but there is no default tool in OpenSolaris to decompress the rar filess. We can got a Solaris Intel version from rarlab . The steps as the following: 1. down load the rar tools from rarlab. http://www.rarlab.com/rar_add.htm 2. uncompressed the source. # gunzip ./unrar-sol-intel.gz 3. move it to the location you used to. # mv /unrar-sol-intel.gz /usr/bin/unrar 4. try to decomprss # unrar x ./test.rar Wish this helps. regards, Stanley Huang

[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
