Today I see two python pitfalls

The first one is in the com.lang.python google group article:
http://groups.google.com/group/comp.lang.python/browse_thread/thread/fe6430e7980e2a96?hl=en#

 if brief . the python import statement may search module in current path first, and files in the same module has very weak relation such as the followiing example that email.py was used in two place and python finds  the wrong one

 bash$ touch email.py
   bash$ python
   ...
   >>> import smtplib
   Traceback (most recent call last):
     File "", line 1, in
     File "/usr/lib/python2.5/smtplib.py", line 46, in
       import email.Utils
   ImportError: No module named Utils


the second is about generator expression, the variable in the clause is not evaluated or stored immediately and may lead a lot of error. To avoid this, list comprehension or closure are the solutions.

As I use python much, I always can find something strange as I use it :<

Use hdaps in X200S in opensuse11.2

Follow  the following links , The idea is clear

http://www.thinkwiki.org/wiki/Tp_smapi#Installation_on_openSUSE

http://forums.opensuse.org/hardware/laptop/417254-tp_smapi-lenovo-thinkpad-t400-t500-w500-step-step.html#post2005932

The main idea is search the build package in opensuse website , just search tp_smapi and hdapsd.  with them , we can perform these commands to turn hard disk protection.


modprobe tp_smapi
modprobe hdaps
/etc/init.d/hdaps restart

check by
smartctl  -a /dev/sda | grep Load_Cycle
