I understand that these methods are for pickling/unpickling and have no relation to the reduce built-in function, but what's the difference between the 2 and why do we need both?

Are you talking about the number of....
When you say 'physical size', are you talking about a print? Because you can just change the printer page size .
Then, release the original image.
You need to draw the image into a graphics context at a smaller size .

Unless you're able to find a fixed point FFT library for python, it's unlikely that the function you want exists... .
It doesn't look like there's any function to do this in scipy's fft functions ( see http://www.astro.rug.nl/efidad/scipy.fftpack.basic.html ) .

See this other question regarding map/reduce:
Generic List Extensions in C#.
The Google document on MapReduce in document etc etc.
Into several smaller problems then a Map-Reduce solution would work.

YSlow is decent for getting an idea as to why it's slow .
YUI's Compressor is one option.
There are also servlet filters out there.
In Apache, use mod_deflate.

Answer Snippets (Read the full thread at stackoverflow):
As Craig notes, when there's a shift reduce conflict, bison does the expected number of shift-reduce conflicts....
You can use precedence declarations to change the behavior.
By default Bison will shift when there is a shift/reduce conflict.

That function and the Javascript packer will reduce the file size of individual files, to get the best configuration settings which reduce the level of compression for other things (especially comments)..
