HP Pavillion Dv2700 intermittent fan

Problem: Laptop (HP Pavillion DV2700) has an intermittent fan. Fan goes on for a second and then stops, goes on again, stops. While this may be OK for the hardware (but who knows) it drives the user nuts.
Cause: Laptop bios upgraded to F.2E (latest)
My Fix: Downloaded and installed F.25 (older version) and this stopped the intermittent fan. I hope that this does not lead to overheating problems, I should monitor CPU temps.

    I can confirm this issue. I just updated the BIOS today to F.2E and immediately got the fan problem you mentioned. HP did a 'Fix' in BIOS version F.2B that allowed the fan to function at low speed when starting the laptop. This fix doesn't seem to work properly on the dv2742 laptop.

    My original BIOS was F.26, but I noticed that on HP only F.25 is available for download. So now I'm obliged to go back to a BIOS one version before the one that originally came with my laptop. Unless there is some way to use the BIOS flash software to restore my previous BIOS?

A note on Python's __exit__() and errors

Python's context managers are a very neat way of handling code that needs a teardown once you are done. Python objects have do have a destructor method ( __del__ ) called right before the last instance of the object is about to be destroyed. You can do a teardown there. However there is a lot of fine print to the __del__ method. A cleaner way of doing tear-downs is through Python's context manager , manifested as the with keyword. class CrushMe: def __init__(self): self.f = open('test.txt', 'w') def foo(self, a, b): self.f.write(str(a - b)) def __enter__(self): return self def __exit__(self, exc_type, exc_val, exc_tb): self.f.close() return True with CrushMe() as c: c.foo(2, 3) One thing that is important, and that got me just now, is error handling. I made the mistake of ignoring all those 'junk' arguments ( exc_type, exc_val, exc_tb ). I just skimmed the docs and what popped out is that you need to return True or

Using adminer on Mac OS X

adminer is a nice php based sqlite manager. I prefer the firefox plugin "sqlite manager" but it currently has a strange issue with FF5 that basically makes it unworkable, so I was looking for an alternative to tide me over. I really don't want apache running all the time on my computer and don't want people browsing to my computer, so what I needed to do was: Download the adminer php script into /Library/WebServer/Documents/ Change /etc/apache2/httpd.conf to allow running of php scripts (uncomment the line that begins: LoadModule php5_module Start the apache server: sudo apachectl -k start Operate the script by going to localhost Stop the server: sudo apachectl -k stop
