**A Magick PIL**
I used to do my image conversions with ImageMagick and system calls back in my PHP days. With Django PIL is the obvious choice for most image stuff, but frustrated by the lack of a proper unsharp mask function for PIL I found some code in the bits and pieces of documentation for PythonMagick. (yes I know, Kevin Cabazon wrote PIL_usm, but I could not get it to work, probably due to my inexperience. Anyway, this code makes it easy to convert back and forth from PIL to PythonMagick (maybe not such a good idea on a memory tight high loaded production server, but no problem on my private server (Pentium-M @ 1.8 Ghz with 1 GB Mem.)
**usage:**
usm takes a PIL image object. Radius and sigma is in pixels, amount 1 compares to 100% in photoshop, threshold 0.004 ~ (1/256) compares to 1 in photoshop: I'm using r=1,s=0.5,a=0.8,t=0.016 for roughly 800x600 images created from 3000x2000 (6MP) images. Experiment for your own preferences.

This middleware will put the sessionid in every place that it might be needed, I mean, as a hidden input in every form, at the end of the document as a javascrit variable to allow the AJAX request use it and of course as a GET variable of the request.
To make it work correctly the MIDDLEWARE_CLASSES tuple must be in this order:
`
'CookielessSessionPreMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'CookielessSessionPosMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
`
Hope it work for someone else out there.

This is a bastardisation of a few of the Amazon s3 file uploader scripts that are around on the web. It's using Boto, but it's pretty easy to use the Amazon supplied S3 library they have for download at [their site](http://developer.amazonwebservices.com/connect/entry.jspa?externalID=134).
It's mostly based on [this](http://www.holovaty.com/blog/archive/2006/04/07/0927) and [this](http://www.davidcramer.net/code/112/writing-a-build-bot.html).
It's fairly limited in what it does (i didn't bother os.walking the directory structure), but I use it to quickly upload updated css or javascript. I'm sure it's a mess code wise, but it does the job.
This will first YUI compress the files, and then gzip them before uploading to s3. Hopefully someone might find this useful. It will also retain the path structure of the files in your MEDIA_ROOT directory.
To use it, set up your Amazon details, download the [YUI Compressor](http://developer.yahoo.com/yui/compressor/), and then enter the folder you wish to upload to s3, and basically run the script - python /path/to/s3_uploader.py
