> Collaborations in healthcare open source
> Link: http://www.chos-wg.eu
> It is about collaboration between healthcare professionals. A
> patient record shared between several health actors in charge of a
> common patient. The family doctor has a coordinating role.
> There's already a lot of health care open source software, but they
> don't talk together. So there is a need for a more modular approach
> in order to share those components. Python seems a good match for
> the project, but they need technical help for this. See the open
> source working groups of theinternational situation for telemedicine
> Reimplementing the google app engine datastore in berkeley DB - java
> edition
> The GAE isn't really portable. That's just for practical issues, not
> by design. One of the barriers is the datastore. So he chose to
> reimplement the datastore (as alternatives weren't practical yet).
> Targeting small to medium apps. In the end he went for BDB which
> shared some features with the original google data store. He uses
> java for it, for instance as Python's protocol buffers are dog slow.
> And the java implementation of BDB is pretty good and solves some
> issues with the normal BDB.
> Python and excel (Chris Withers)
> Python and excel: you could use CSV or the "HTML hack". There's
> something better: xlrd. This can directly read and write excel files.

> tl.eggdeps (Thomas Lotze)
> Link: http://pypi.Python.org/pypi/tl.eggdeps
> It collects declared dependencies between eggs as a tree. And it can
> visualize them using dot/graphviz. You can filter out uninteresting
> packages (like setuptools) and zoom in on the dependencies of one
> specific package. You can also group for instance all zope.tal.*
> packages into one zope.tal node to make the image cleaner. And you
> can even filter by regular expression.
> MOAI (Kit Blake)
> MOAIis an open access server platform for institutional
> repositories. The server manipulates OAI feeds that are in some xml
> format. One of the users is http://www.cwi.nlwhich actually is the
> birth place of Python. Infrae harvested the 8963 documents in CWI's
> repository. So in the demo Kit was able to find 16 documents by a
> certain Guido van Rossum from 1995.
> So 14 years after Guido left CWI, the first fully fledged Python
> application is installed at CWI. Python has come home!
> The cloud in Five (Kevin Noonan)
> He demonstrates amazon's cloud stuff. Cloudware is outsourced
> virtualization. So a virtual server or storage hosted on a remote
> platform. The two well known once are Amazon Web Services and
> Google's app engine. It is good for scaling on demand. And you can
> get some outsourcing of your infrastructure. The oldest of Amazon's
> web services is S3, the storage solution. There are Python libraries
> to connect to it and manage it.
> How to hack like an evil overlord (Jonathan Lang)
> How to hack like an evil overlord in five easy steps:
> Shooting is not too good for my enemies. There is no software bug
> for which shooting is not the good solution.
> Take a 5 year old as an advisor. They will always spot the flaws in
> your plans. So always have someone else look at your code.
> Do not consume any more energy than will fit in your head. So no
> metaclasses.
> If I have an unstoppable superweapen, I will use it as early and
> often as possible. So pdb instead of print statements.
> "Push the button" should be enough. Automate everything. Don't do
> long manual steps or the hero will slay you.
> Internet censorship (Holger Krekel)
> Governments are turning the internet and the mobile networks into
> the greatest mass surveillance system ever. Iran likes that as it
> can useoursurveillance software and our data-retaining mobile
> infrastructure to retain all the protesters SMS messages and analyze
> them afterwards... So our western measures enacted for our
> protection is going to send thousands of Iranians into the torture
> chambers.
> And the government in some countries is allowed to put trojan horses
> on your devices. And the government in Germany can in the future
> sensor any webpage they want. Just by executive decision instead of
> democratic process. And France tries to put a three-strikes law into
> effect.
> And all that even though the internet is so great. But it is turning
> into a huge surveillance database for the government. There are
> technical counter-strategies. Unlocatable content. Untrackable
> connections. Untrackable access. And there are political counter-
> strategies like blogging, involvement, twitter, etc.
> So support political actions and create cooler technology! For a
> free internet.
> CMS in django (Tommi)
> He showed an event-like system used for re-rendering placeholder-
> tags in an html page with the real content.
> SciPy (Stefan Schwarzer)
> At the end of July there'll be a European conference for Python in
> science in Leipzig, Germany. http://www.euroscipy.org
> PyCharm (Dmitry Jemerov)
> They're working on a new Python IDE: pycharm. Currently a plugin for
> intelliJ IDEA, but soon standalone. See http://www.jetbrains.com.
> Price not yet announced, should be available later this year.
> He demoed it with nice warnings, quite intelligent autocompletion.
> Integrated test support. Snippets. Display of docstrings for methods
> with just a keyboard shortcut.
> Psyco 2.0 (Christian Tismer)
> He showed a speed test of a normal and a pure Python property
> implementation to see how much psyco2 can speed that up. On average,
> there was a 100x improvement. There'll be a psyco2 release on
> Saturday.
> Self-service terminals (Bernard Nikolaus)
> There are self-service terminals at his university
> (Wirtschaftsuniversitaet Wien), implemented with Python, for paying
> study fees, taking photos, etc. So a card reader, printer, touch
> screen, etc. All vandal-proof.
> The hardest thing of the project was to communicate with all the
> hardware. There's a watchdog that monitors a subversion repo for
> updates. And it starts the main program. Zope is used with xmlrpc
> for the data. The data is stored in an oracle database. The use
> mostly WXPython widgets for the user interface. Quite big buttons as
> the interface is a touch screen.
> Jacob Hallen
> Please use political activism to prevent the recording industry from
> being allowed to lift us from our beds in the middle of the night
> for horrid crimes like downloading stuff or even developing open
> source software. It isa very real danger. We prevailed against
> software patents after a long struggle. Therearepoliticians that are
> willing to listen, but wemust be the ones to do the talking.
> Python system information
> PSI is a Python C extension to get information from the kernel via
> system calls and kernel hooks and so. It currently supports most
> unixy platforms already, but BSD is lacking and windows too. They do
> want to add that.
> Twisted interface to Erlang (Thomas Herve)
> TwOTP: twisted interface to Erlang. http://launchpad.net/twotp.
> Erlang is a functional language with a focus on scalability. There
> is an "ERM" protocol to communicate between nodes, which is
> documented. CouchDB is one of the nice applications made with
> Erlang. But as a Python programmer we want to access that too.
> TwOTP has parsing/packing to/from Python types, an EPMD deamon
> implementation and implementations for server and client protocols.
> And monitoring of Erlang processes. Send and receive messages from/
> to Erlang processes. The good thing: every Python goodie is
> available to develop with, like UI, web libraries and database
> interfaces. Several of those things are hard(er) with Erlang.
> Python for numerical analysis (Eric)
> Most numerical analysis is still done with Fortran. Not nice. So he
> tried to do it with Python. All the goodies like eigenvalues, green
> functions, plots of the green functions. The number of lines in the
> program was much lower than with a comparable Fortran program. He
> hopes that the Python community will work towards promoting the
> scientific application of Python. It is so much nicer.
> FilterPype network (Rob Collins)
> Filterpype: "complex systems in 10 lines of code". A classic case of
> a filter and pipe system is an oil refinery. With filterpype you can
> also work with pipes and filters: from source to sink.
> There are base classes for all sorts of filters. Stuff you can do?
> Just pass it on, bzip compression, etc. You tie the filters together
> in a pipeline with a small config file that specifies the route
> between the various filters.
> Link: http://www.filterpype.org/
> TPS reports in django (Felix)
> Django's admin interface is highly customizable. At his company he
> needed to make some modifications, especially adding reports for
> their issues database. In the end, he generated reports with word by
> using a template in word's xml format where he could get the
> software to fill in data. The template was simply uploaded to the
> site. The documentation on how he did it is all on the wiki of
> djangoproject.org.
> Distributed version control system (Radomir Dopieralski)
> Use it, it really changes the way you program. It is real easy to
> make a clean copy of something, work on it and possibly push the
> changes back. He thinks there should be more tools like that. For
> instance for bug reports: there is a tool that embeds bug reports in
> such a DVCS.
> hattais something that he made that embeds a wiki in the DVCS,
> including the whole page history. It comes with a small web server
> that you run straight from your DVCS checkout, so you can easily
> browse your version of the wiki and even change it via the web
> interface. And also directly in the source file, of course.
