Two day Twisted training in San Francisco, March 11-12 (right before PyCon)

[Itamar Turner-Trauring]

Twisted (http://twistedmatrix.com) is a robust, mature, open source
event-driven networking framework written in Python. Supported features
range from low-level network transports such as TCP, SSL, UDP, and
multicast, to high-level protocols including HTTP, DNS, SSH, SMTP and IMAP.
Twisted is used by companies large and small, including Apple, Justin.tv,
Canonical (makers of Ubuntu) and TweetDeck, and by open source projects
like Tahoe-LAFS.

If you want to build reliable, well-tested network applications in Python,
Twisted may be the tool you need. In this two-day class we will cover the
basic principles and core APIs of Twisted. Covered material will include

   - Understanding Event Loops: we'll re-implement Twisted's core APIs
   step-by-step (reactor, transport, protocol), explaining the why and how of
   event-driven networking.
   - TCP Clients and Servers.
   - Scheduling Timed Events.
   - Deferreds: the motivation and uses of Twisted's result callback
   abstraction.
   - Producers and Consumers: dealing with large amounts of data.
   - Unit Testing: how to test your networking code.
   - A large, self-paced exercise, implementing a HTTP server and client
   from scratch using pre-written unit tests as guidance, and our help as
   needed.

The class will take place on the Monday and Tuesday before PyCon 2013, so
might be suitable for out-of-town visitors as well.

Cost is $650 (early bird, available until Feb 15th), or $750 after that.

maintainers since 2002, and is the maintainer of pyOpenSSL.

Itamar Turner-Trauring spent many years working on distributed applications
as part of ITA Software by Google's airline reservation system, coding in
Python (often using Twisted), C++ and a little bit of Common Lisp. Itamar
has also worked on projects ranging from a reliable multicast messaging
system with congestion control, a prototype-based configuration language,
to a multimedia kiosk for a museum. Itamar has been one of the core Twisted

Eventlet 0.11 bug fix release

[Sergey Shepelev]

Hello. Eventlet 0.11 is available.
http://pypi.python.org/pypi/eventlet/0.11.0

This is a quick bug fix release featuring:
* ssl: Fix busy loop in socket.sendall(). Thanks to raylu.
* zmq: Return linger argument to Socket.close(). Thanks to Eric Windisch.

What's next: zmq .bind(PUB) busy loop fix, modernized documentation, 
contributor friendly PEP-8 and style fixes.

We still have lots of work to do. We need smart people like you to help with 
these:
* For easy start, join discussion on project development path. Nose or py.test? 
Which pep8 messages to ignore? 
https://plus.google.com/u/0/109869205442495270563/posts/BhRip2sG128
* Always need various environments to run tests. Automated build agent would be 
super awesome.
* https://github.com/eventlet/eventlet/issues?state=open
Particularly #2 has working patch and needs tests, #6 Python3 support, #7 weird 
importing popular `requests` library, #8 IPv6 support
* https://bitbucket.org/which_linden/eventlet/issues?status=newstatus=open - 
61 open issues: some are dead easy, some can keep you thinking all week
