An "enum" for Python 3
An unexpected perf feature
LWN.net Weekly Edition for May 16, 2013
A look at the PyPy 2.0 release
I'm not sure I can think of an area of computing that has seen such reliable, abject failure. KDE4 is the only project I know of that has seen some success but nobody I know uses those features.
Plasma Active Three released

When they don't even appear to notice those previous problems it creates the impression that they'll end up in the same place as those other projects.

It's human nature, I guess.

I used to work on the Agent Development Kit when I was with Tryllian around 2000... Intelligent, mobile agents with shared ontologies! And a total turnover for the 100+ company until it went broke of 10k euros. Tryllian even bought its own 4-floor office building before the ex-xerox salesperson had ever sold a single license. Every year those licenses got more expensive, to cover the development investment. But I really learned a lot about coding at Tryllian.

Neural networks are widely used in things like text and speech recognition (they are not all that they were hyped up to be, but they are still useful).
Ontologies are dead - they're semantic computing thingy, duh.
Expert systems, fuzzy logic and AI are used more and more: just check those Kinect sensors or Google's self-driving cars.
I'm sure, we can find even more dismal areas than semantic computing, but it's not an easy task :)

Compare with the Turing test: impersonating a real human in a conversation. I don't think Wolfram Alpha qualifies, even though I have had many conversations more boring than a single search in the Alpha engine.

Google's self driving cars are programmed with a mix of clever algorithms, classical AI algorithms and new machine learning techniques. All put together leads to some surprising results on the tests.
I had the opportunity to take Thrun and Norvig's course on AI (www.ai-class.com), and I can say that the field has advanced more in the latest 5 years alone than in the previous 30. It's well worth the effort:

> Intelligent agents (supposed to bid for you on eBay)?
They exist (not smart, but they exist), so I guess it depends on your definition of 'Intelligent'. Some definitions make this part of the AI question.
> Mobile agents (supposed to migrate from one machine to the next)?
still being promised and worked on. showing up more commonly in movies and TV shows (especially the high-tech crime dramas). probably going to arrive relatively soon for a small subset of things to move apps between mobile devices and more powerful permanent devices.
Once you get the ability to run Android apps on Linux desktop systems you have all the pieces in place. The apps checkpoint themselves so that they can be stopped and restarted, so stopping an app on a mobile device and restarting it on a desktop device should be straightforward
> Neural networks?
Very common, just not highly visible.
Very common, just not in schools (it's how a lot of technical training takes place nowdays
> Meta-programming (programs that programmed other programs?
it exists, but as a niche
> Expert systems? Fuzzy logic?
both of these are extremely common, you probably just don't recognize them when you bump into them.
Expert systems dominate tech support systems for example.

I meant to say that most of the things you are talking about are acutlaly fairly common, you just don't know what's happening under the covers.
