simplejson (documentation) is a simple, fast, complete, correct and extensible JSON (RFC 4627) encoder/decoder for Python 2.3+. It is pure Python code with no dependencies, but features an optional C extension for speed-ups.

simplejson 2.0.4 is a minor bug-fix update:

• Fixes a parsing error in the C extension when the JSON document is (only) a floating point number. It would consume one too few characters in that case, and claim the document invalid.

MochiKit 1.4 was released today: download, announcement.

simplejson 2.0.3 is an important bug-fix update:

• Fixes reference leaks in the encoding speedups (sorry about that!)
• Fixes doctest suite for Python 2.6
• More optimizations for the decoder

I don't often post about open jobs at Mochi Media on my blog, but it seems that most of the awesome people we have here found out about Mochi Media from me so I might as well ;)

Web development at Mochi Media happens primarily in Python and Pylons with Genshi templates. We're currently using mostly MochiKit for the JavaScript heavy lifting and we talk to all of our backend services (which are either Python or Erlang) via JSON. We're using a bunch of other cool technologies such as memcached, nginx, PostgreSQL, etc. We also often contribute a lot of what we do back to the open source community (e.g. MochiKit, MochiWeb, simplejson, etc.) and would love adding some more team members that were interested in helping out with our open source efforts too! We don't require experience with all of these frameworks and tools, we just need smart people that have a really solid understanding of web development in Python.

Mochi Media runs MochiAds, a monetization platform for Flash games, and MochiBot, an analytics service for Flash content... so we've got tons and tons of data to work with and very interesting scale problems to address. Our primary service, MochiAds, is a monetization platform for Flash games... so part of the responsibilities of being a Mochi employee is to approve all the latest in Flash games for paid advertisements from our network ;) There's even an internal competition to see who approves the most games each week! You can check some of them out at http://www.mochiads.com/games/

Mochi Media was founded in 2005 by Jameson Hsu and myself, and we're backed by Accel Partners and Shasta Ventures. We've got a great team and are always looking to add the best people we can find. If you kick ass at Python and love building cool apps for the web, talk to us!

This position is full-time and on-site in San Francisco, CA. We're very easily accessible by BART and Caltrain in SOMA, at 2nd st. and Mission st. More evidence that Mochi Media is a cool place to work can be found on the mochimedia Flickr photostream: http://flickr.com/photos/mochimedia

simplejson 2.0.2 is a minor update:

• Fixes MSVC2003 build regression
• Fixes Python 2.4 compatibility in _speedups.c

Python 2.6 was released yesterday, which has tons of cool new features including a new json library and a new multiprocessing library. The json library is basically simplejson (from a few months ago) minus the Python 2.4/2.5 support and refactored to take advantage of the latest future-compatible features (such as the new str.format method instead of using % format interpolation).

The only downside is that I wasn't able to get the latest simplejson 2.0.1 performance enhancements into the first release of Python 2.6, but expect them for Python 2.6.1! Don't worry though, simplejson should install just fine with Python 2.6 if you need the speed. If not, you don't have any dependencies for JSON anymore, just change your imports:

# Use simplejson or Python 2.6 json, prefer simplejson.
try:
    import simplejson as json
except ImportError:
    import json

print repr(json.dumps({'key': 'serialize this!'}))
print repr(json.loads('{"key": "deserialize this!"}'))

One of my favorite features in json/simplejson is the shell command that will validate/pretty print JSON. Great for debugging, and it will be sweet to have it available on every box with Python 2.6+!

A really cool tip if you're using Mac OS X is that you can access the string version of the pasteboard from the shell with pbpaste and pbcopy. This will take the JSON from your pasteboard and replace it with a pretty-printed version! If you're using simplejson just change json.tool to simplejson.tool. I'm sure this would be super handy in a text editor macro too:

$ pbpaste | python -mjson.tool | pbcopy
