Vista, HP DV2210us freezes at start of waking from sleep/hibernation

[also see this]

This is a HP dv2210us which has a Go 6150 graphics card. From this microsoft knowledge base entry, assuming that this card has a PCI-E bus (NVIDIA tech specs), I need this hotfix.

The hot fix doesn't work for me.

The computer is now such that it will not boot up easily - it gets stuck at a blank screen whenever I switch it on. I have to coax it to get past what ever is stopping it by hitting f8 and catching it at the right boot phase.

I'm gonna wipe the hibernation file and see if that works. No

I do get an error - \boot\memtest.exe 0xc0000221 file possibly corrupt, header checksum does not match the computed checksum.

I think I will restore the computer to the factory default (yes, I do not have vista disks, thank you HP and Microsoft).

2008.03.18: I think the computer has a problem shutting down when it is asked to restart.

2008.03.22: Apparently the HP service techs know about this problem and will fix it since it is under warranty. They promise delivery on April 15, so I will be laptop free for about 3 weeks at least. That said HPs warranty covers home pickup and delivery, so thats a bit less hassle. Now if only they had a loaner laptop service...

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...

Remove field code from Word document

e.g. before submitting a MS, or hand manipulating some formatting because Word does things (like cross-references) so half-assed [from here ] Select all the text (CTRL-A) Press Ctrl+Shift+F9 Editing to remove anonymous comments that only contain thanks. I really appreciate the thanks, but it makes it harder to find comments that carry pertinent information. I'm also going to try and paste informative comments in the body of the post to make them easier to find.

h5py and multiprocessing

The HDF5 format has been working awesome for me, but I ran into danger when I started to mix it with multiprocessing. It was the worst kind of danger: the intermittent error. Here are the dangers/issues in order of escalation (TL;DR is use a generator to feed data from your file into the child processes as they spawn. It's the easiest way. Read on for harder ways.) An h5py file handle can't be pickled and therefore can't be passed as an argument using pool.map() If you set the handle as a global and access it from the child processes you run the risk of racing which leads to corrupted reads. My personal runin was that my code sometimes ran fine but sometimes would complain that there are NaNs or Infinity in the data. This wasted some time tracking down. Other people have had this kind of problem [ 1 ]. Same problem if you pass the filename and have the different processes open individual instances of the file separately. The hard way to solve this problem is to sw...
