I gave a talk at PyCon 2010 in Atlanta last month called Analysis: The Other Kind of Testing (video). It's a very simple overview of techniques such as split testing (AB testing) and a call to action to improve django-lean.

Atlanta was a fantastic location for PyCon 2010, and I look forward to returning next year. Hopefully if I give another talk I'll be able to put a little more time into it :)

As per usual, I've been incredibly lazy about updating this blog, so you're much better off following @etrepum on Twitter.

simplejson (documentation) is a simple, fast, complete, correct and extensible JSON (RFC 4627) encoder/decoder for Python 2.5+. It is pure Python code with no dependencies, but features an optional C extension for speed-ups.

simplejson 2.1.0 is a major update with several new features and bug-fixes:

• Decimal serialization officially supported for encoding with use_decimal=True. For encoding this encodes Decimal objects and for decoding it implies parse_float=Decimal
• Python 2.4 no longer supported (may still work, but no longer tested)
• Decoding performance and memory utilization enhancements http://bugs.python.org/issue7451
• JSONEncoderForHTML class for escaping &, <, > http://code.google.com/p/simplejson/issues/detail?id=66
• Memoization of object keys during encoding (when using speedups)
• Encoder changed to use PyIter_Next for list iteration to avoid potential threading issues
• Encoder changed to use iteritems rather than PyDict_Next in order to support dict subclasses that have a well defined ordering http://bugs.python.org/issue6105
• indent encoding parameter changed to be a string rather than an integer (integer use still supported for backwards compatibility) http://code.google.com/p/simplejson/issues/detail?id=56
• Test suite (python setup.py test) now automatically runs with and without speedups http://code.google.com/p/simplejson/issues/detail?id=55
• Fixed support for older versions of easy_install (e.g. stock Mac OS X config) http://code.google.com/p/simplejson/issues/detail?id=54
• Fixed str/unicode mismatches when using ensure_ascii=False http://code.google.com/p/simplejson/issues/detail?id=48
• Fixed error message when parsing an array with trailing comma with speedups http://code.google.com/p/simplejson/issues/detail?id=46
• Refactor decoder errors to raise JSONDecodeError instead of ValueError http://code.google.com/p/simplejson/issues/detail?id=45
• New ordered_pairs_hook feature in decoder which makes it possible to preserve key order. http://bugs.python.org/issue5381
• Fixed containerless unicode float decoding (same bug as 2.0.4, oops!) http://code.google.com/p/simplejson/issues/detail?id=43
• Share PosInf definition between encoder and decoder
• Minor reformatting to make it easier to backport simplejson changes to Python 2.7/3.1 json module

I'm getting increasingly lazy about updating my blog these days, probably best to follow me on twitter: http://twitter.com/etrepum

Anyway, I gave a talk at PyCon 2009 in Rosemont ("Chicago") last week called Drop ACID and think about data. Basically it is a survey of some of the various kinds of non-traditional database technologies I've been looking at the past few years. Notable technologies NOT talked about are object databases and graph databases. *UPDATE* Video available here: http://blip.tv/file/1949416

Slides are on BitBucket for now: Drop ACID and think about data

I'll be giving a (hopefully updated) version of this talk at OpenSourceBridge, which is in Portland, OR June 17-19.

If you're interested in the content of this talk there is far more insightful information on Jonathan Ellis' Programming Blog, one of the developers working on Cassandra.

simplejson (documentation) is a simple, fast, complete, correct and extensible JSON (RFC 4627) encoder/decoder for Python 2.4+. It is pure Python code with no dependencies, but features an optional C extension for speed-ups.

simplejson 2.0.9 is a major bug-fix update:

• Adds cyclic GC to the Encoder and Scanner speedups, which could've caused uncollectible cycles in some cases when using custom parser or encoder functions

simplejson (documentation) is a simple, fast, complete, correct and extensible JSON (RFC 4627) encoder/decoder for Python 2.4+. It is pure Python code with no dependencies, but features an optional C extension for speed-ups.

simplejson 2.0.8 is a minor bug-fix update:

• Documentation fixes
• Fixes encoding True and False as keys
• Fixes checking for True and False by identity for several parameters

simplejson 2.0.7 is a minor bug-fix update:

• Documentation fixes
• C extension now always returns unicode strings when the input string is unicode, even for empty strings

simplejson (documentation) is a simple, fast, complete, correct and extensible JSON (RFC 4627) encoder/decoder for Python 2.4+. It is pure Python code with no dependencies, but features an optional C extension for speed-ups.

simplejson 2.0.6 is a minor bug-fix update:

• Windows build fixes

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 2.0.5 is a minor bug-fix update:

• Fixes a segfault in the C extension when using check_circular=False and encoding an invalid document

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.

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 2.0.3 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
