Its aim is to take over the whole i ntellectual property "Zope" from Zope Corporation and lead Zope's further development as OpenSource software\, but now owned by a non-profit organi sation.\nThis talk is about the future of Zope from the point of view of t he Zope Foundation. Two members of the ZF Board of Directors\, Martijn Fa assen and Aroldo Souza-Leite\, will be present.\n\nhttp://indico.cern.ch/c ontributionDisplay.py?contribId=24&sessionId=19&confId=13919 LOCATION:Vilnius\, Lithuania Lambda URL:http://indico.cern.ch/contributionDisplay.py?contribId=24&sessionId=19 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Introduction to Web Programming with WSGI DTSTART;VALUE=DATE-TIME:20070711T070000Z DTEND;VALUE=DATE-TIME:20070711T073000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-25@cern.ch DESCRIPTION:Speakers: Dr. SIMIONATO\, Michele (StatPro Italy)\nAs the old saying goes\, Python is the only language with more Web frameworks than \nkeywords. This is sometimes an advantage\, but more often than not\, it is an issue. \nIn order to improve the interoperability between differe nt frameworks\, Phillip \nJ. Eby proposed in 2003 a specification\, the WSGI or Web Server Gateway \nInterface\, a.k.a Whiskey. I n my talk I will discuss how you can achieve portability \nof your applic ation by following the WSGI specification. I will give practical \nexamples of how to use the WSGI reference implementation which is part of the \nstandard library (wsgiref)\, of how to supplement it with other WSGI-compliant \nlibraries (notably Paste by Ian Bicking) an d of how to integrate your WSGI \napplication in different frame works including Zope\, Twisted\, TurboGears et al. \nThe talk is int ended as a tutorial and requires only elementary knowledge of \nWe b programming\, at the level of simple CGI.\n\nhttp://indico.cern.ch/contr ibutionDisplay.py?contribId=25&sessionId=19&confId=13919 LOCATION:Vilnius\, Lithuania Zeta URL:http://indico.cern.ch/contributionDisplay.py?contribId=25&sessionId=19 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Python Data-Driven Parsing For The Real World DTSTART;VALUE=DATE-TIME:20070710T100000Z DTEND;VALUE=DATE-TIME:20070710T103000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-26@cern.ch DESCRIPTION:Speakers: Dr. STOVALL\, Johnny (Dr. Stovall Foundation for Pra ctical Education and Social Development)\nData-driven parsers have been us ed in AI and inductive reasoning in ways beyond the abilities of rule-driv en parsers. This paper presents an annotated bibliography and guidelines for developing multipurpose data-driven parsers in hopes that developers w ill assist the author in disaster recovery and OLPC development\, will pus h Free Open Software to new heights\, and will benefit from commercial opp ortunities. \n\nData-driven parsers of the highest types don't require a p redetermined set of rules like rule-driven parsers do. This is most like discovery learning that maybe helps children to learn their first language so easily and fluently. The author contends this same type of learning i s necessary for natural responses to a wide variety of real world situatio ns. The data drives the progress and in the higher types can change goal s just like it real life. Rule driven parsers are primarily useful in clo sed languages such as computer programs where the parser developer can kno w all of the rules before starting.\n\nDeclarative programming will also b e briefly described. This is an underused part of Python's flexibility bu t the basis for some data-driven parsers.\n\nhttp://indico.cern.ch/contrib utionDisplay.py?contribId=26&sessionId=20&confId=13919 LOCATION:Vilnius\, Lithuania Theta URL:http://indico.cern.ch/contributionDisplay.py?contribId=26&sessionId=20 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Managing Source Code with Bazaar DTSTART;VALUE=DATE-TIME:20070710T130000Z DTEND;VALUE=DATE-TIME:20070710T133000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-27@cern.ch DESCRIPTION:Speakers: Mr. HUDSON\, Michael (Canonical)\nBazaar is a safe\, friendly\, free and fast distributed version control system.\n\n(will add more here soon)\n\nhttp://indico.cern.ch/contributionDisplay.py?contribId =27&sessionId=27&confId=13919 LOCATION:Vilnius\, Lithuania Lambda URL:http://indico.cern.ch/contributionDisplay.py?contribId=27&sessionId=27 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Silva 2.0 DTSTART;VALUE=DATE-TIME:20070709T143000Z DTEND;VALUE=DATE-TIME:20070709T150000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-20@cern.ch DESCRIPTION:Speakers: Mr. BLAKE\, Kit (Infrae)\nSince it's launch at EuroP ython 2002\, Silva has grown into a powerful CMS for\norganizations that m anage complex websites.

Enhancing Python and developing the CPython runtime\nhave becom e interchangeable activities. Those who tried to extend Python had to be\n core developers of CPython or at least experimenting with one of the alter native\nruntime environments like PyPy\, IronPython or Jython. For those w ho had research\ninterests in the language or writing domain specific lang uages on top of Python this\nhas always been an obstacle. \n\nEasyExtend i s a grammar based code generator and Python preprocessor framework in the\ ntradition of Lex/Yacc and ANTLR but written in pure Python and seamlessly integrated\nwith Python. EasyExtend is also inspired by the languages-as -components metaphor\nwhich is reified in its so called fiber-space archit ecture.\n\nThis talk will give a short introduction into EasyExtend\, its design and prospectives.\n\nhttp://indico.cern.ch/contributionDisplay.py?c ontribId=21&sessionId=20&confId=13919 LOCATION:Vilnius\, Lithuania Theta URL:http://indico.cern.ch/contributionDisplay.py?contribId=21&sessionId=20 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:If you can't beat them ...

Microsoft Office! Especially in intranet\nenviroments.\nThing s\, especially versioning and tracking of changes\, can go horribly wrong when\npeople start working together\, sending eachother Office documents.\ nTo accomodate this problem\, Microsoft came up with Sharepoint.\n\nA full -blow Sharepoint implementation can get horribly expensive. However\,\nthe basic functionality of Sharepoint is a free addition to Windows Server 20 03\nunder the name Sharepoint Portal Services.\n\nDuring this talk a gener al introduction on Sharepoint will be given\, followed by\nan exploration of the way the Sharepoint Services can be leveraged\nfrom the python world .\n\nhttp://indico.cern.ch/contributionDisplay.py?contribId=22&sessionId=2 7&confId=13919 LOCATION:Vilnius\, Lithuania Lambda URL:http://indico.cern.ch/contributionDisplay.py?contribId=22&sessionId=27 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:OpenAlea - Visual Programming and Component based software for pla nt modeling DTSTART;VALUE=DATE-TIME:20070709T090000Z DTEND;VALUE=DATE-TIME:20070709T093000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-23@cern.ch DESCRIPTION:Speakers: Mr. DUFOUR-KOWALSKI\, Samuel (INRIA)\nBuilding plant models at different scales requires integrating tools from various scient ific domains such as biology\, computer science\, and mathematics. The ope n source OpenAlea project's goal is to define a framework to share and reu se heterogeneous models from the plant modeling community. A visual enviro nment is made available to researchers to ease the building of high-level computational tasks in a simple and flexible way. \n\nThe core of OpenAlea \, implemented in Python\, consists of a component framework that allows f or the dynamic management and composition of software components. A compon ent is a Python callable object with input and output ports. Components co mmunicate through their ports\, and can be interconnected to form complex processing graphs. A package is a deployment unit that provides components \, data\, and widgets as well as meta-information. The package manager is able to find and load dynamically packages installed on the computer witho ut specific configuration. A series of packaging tools\, SconsX and Distx\ , based on SCons and Distutils\, have been developed to ease the distribut ion of complex C++ extensions\, and to share dynamic libraries between dif ferent OpenAlea packages.\n\nA special application\, Visualea\, has been c reated as a PyQt4 visual programming environment to edit and run dataflow. For each component\, graphical widgets can be either provided by user pac kages or generated automatically\, based on their input port interfaces. T his makes it possible to reuse widgets in different packages.\n\nMore info rmation on OpenAlea is available at http://openalea.gforge.inria.fr.\n\nht tp://indico.cern.ch/contributionDisplay.py?contribId=23&sessionId=22&confI d=13919 LOCATION:Vilnius\, Lithuania Theta URL:http://indico.cern.ch/contributionDisplay.py?contribId=23&sessionId=22 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Integrating Python and TeX: MathTran and beyond DTSTART;VALUE=DATE-TIME:20070710T093000Z DTEND;VALUE=DATE-TIME:20070710T100000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-28@cern.ch DESCRIPTION:Speakers: Dr. FINE\, Jonathan (The Open University)\nThis talk describes the MathTran system for translating mathematics from TeX to Mat hML and vice versa\, and its use of TeX as a daemon. It surveys related P ython and TeX software\, and calls for the creation of standard Python lib rary modules as a means of unifying and simplifying these projects.

It is largely command compatible with the lead ing commercial\nCAD\, but it differtiantes to a few concepts such as hiera rhcical layers\, and lack of\nelements attributes\, which is the CAD equiv alent to structured programming. ThanCad\nadds some productivity tools suc h as line continuation\, layer selection and\ncross-save/read undo mechani sm. ThanCad harnesses the power of Python to shrink the\ndevelopment time and the volume of code\; to implement and test new ideas in virtually\nno time\; to make ThanCad programmable without the need of separate librari es\,\nplug-ins\, special languages\, or special OSes\; to make 32bit/64bit processor\, OS and\nOS version irrelevant. ThanCad uses Tkinter\, the def acto GUI/drawing standard for\npython\, in order not to reinvent the whee l and to achieve platform independence.\nSeveral concepts were addressed s uch as compound elements\, text in arbitrary\ndirections\, cursor/crosshai r\, zoom\, image zoom\, coordinate systems tracking\, image\nresolution\, draworder\, object snap\, different element intersection\, mouse wheel\nwi ndows/linux differences\, input from command window and/or GUI\, hierarchi cal modal\nwindows. Finally\, ThanCad uses Python's object oriented progra mming\, but sometimes it\nfollows the Zen of Python and the Linux kenel's philosophy\, practicality beats purity.\n\nhttp://indico.cern.ch/contribut ionDisplay.py?contribId=0&sessionId=22&confId=13919 LOCATION:Vilnius\, Lithuania Theta URL:http://indico.cern.ch/contributionDisplay.py?contribId=0&sessionId=22& confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Case study of a Pylons project DTSTART;VALUE=DATE-TIME:20070709T090000Z DTEND;VALUE=DATE-TIME:20070709T093000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-4@cern.ch DESCRIPTION:Speakers: ISCHENKO\, Max (Author)\nThe talk is a case study fo r my experience rebuilding a PHP-powered site in Python. \n\nPrimarily foc us is Pylons which is a modern\, cool and immature web framework\,\ncurren tly heading for 1.0 release.

"If you can't measure it\, it doesn't exist." Both useful adages\, but how do you measure the performa nce of a Python program and identify bottlenecks?\n\nIn my talk I'll start with generating simple timing numbers and how to interpret the results. I'll show how to use Python's profiler and convert the results for kcacheg rind\, a KDE profile visualization tool. Sometimes function-call level in formation is too detailed or otherwise inappropriate so I'll show how to i nstrument and create higher level traces for kcachegrind.\n\nI used all of these techniques while consulting for AstraZeneca's R&D group.

Python’s interpreter is of great help if you don’t have any clue a bout programming languages and would like to make your first steps into ro botics and programming. Simple scripts to control your robot are really at your fingertips.\n \nYou can easily stream music and sounds to and from T ux Droid\, blinking the eyes\, wave the flippers\, spin\, send and receive IR codes or detect if the head button is pressed. Tux Droid’s embedded processing is only meant to interface sensors and actuators. But by develo ping a complete python API\, we can leverage the embedded basic set of fea tures to get a complex robot which can bring life to your applications and act as a desktop companion.

Non-standard rate coefficient functio ns can be handled by a user supplied shared library.\nPLASMAKIN is based o n a shared library with data reading and computational functions and a Pyt hon module based on the ctypes foreign function library and providing pyth on function interfaces and classes.\nTogether with other Python numerical and data plotting libraries such as SciPy and matplotlib\, PLASMAKIN allow s a fast and efficient analysis of plasma physics problems.\n\nhttp://indi co.cern.ch/contributionDisplay.py?contribId=54&sessionId=22&confId=13919 LOCATION:Vilnius\, Lithuania Theta URL:http://indico.cern.ch/contributionDisplay.py?contribId=54&sessionId=22 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:3D Geo-portal Visualization Software for Control Rooms in the Oil and Gas Industry using Python DTSTART;VALUE=DATE-TIME:20070710T070000Z DTEND;VALUE=DATE-TIME:20070710T073000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-57@cern.ch DESCRIPTION:Speakers: Mr. FAHMY\, Tamer (Kongsberg SIM)\, Mr. SEEHUUS\, Ro lv (Kongsberg SIM)\nOff-shore operations in the oil and gas industry are b ecoming increasingly expensive and complex. One of the strategies to overc ome this development is to create operation centers on-shore.\n\nCentraliz ing the control of oil-fields allows field-managers to make optimal decisi ons in a global scale. However\, the amount of information they must proce ss increases dramatically.\n\nWe present the application Vispo3D Operation s. Vispo3D Operations ties together information from various data sources and provide an overview of the current situation in the North Sea. The dec ision making is facilitated by providing 3D visualization for various aspe cts in oil-rig management\, such as the simulation of the current weather conditions.\n\nThe application is implemented almost exclusively in Python . Due to the novel and challenging requirements of the project for both de velopers and customers\, Python proved to be a valuable tool for Rapid App lication Prototyping and more importantly for explorative development.\n\n The original plan was to re-implement the whole solution in C++. However\, the Python version proved to be sufficiently responsive and adequate\, ve ry flexible and especially adaptable with regards to the changing requirem ents.\n\nVispo3D Operations makes use of Kongsberg SIM's mature 3D visuali zation libraries and toolkits collectively named Coin3D. Coin3D is a high- level\, retained-mode visualization suite for effective 3D graphics develo pment\, which is cross-platform\, open source and without any royalties or run-time fees for professional licensees.\n\nConsequently\, Python bindin gs for Coin3D\, called Pivy\, were created to interface with the Coin3D C+ + libraries. PyQt from Riverbank and Qt from Trolltech are used for the gr aphical user interface. CherryPy\, a pythonic\, object-oriented HTTP frame work\, is used for client server communication\, as well as serving a web- interface for off-shore users. The data itself is stored in SQLite databas es\, which is fetched through XML-RPC from the clients.\n\nThe decision to use Python proved to be very rewarding and allowed us to cope with the ch anging and demanding requirements from the customer with ease. The success ful usage of Python within this project convinced upper management to leve rage the advantages and benefits of Python for further upcoming new projec ts.\n\nhttp://indico.cern.ch/contributionDisplay.py?contribId=57&sessionId =27&confId=13919 LOCATION:Vilnius\, Lithuania Theta URL:http://indico.cern.ch/contributionDisplay.py?contribId=57&sessionId=27 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Using FormEncode for web data validation DTSTART;VALUE=DATE-TIME:20070709T100000Z DTEND;VALUE=DATE-TIME:20070709T103000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-56@cern.ch DESCRIPTION:Speakers: Mr. STRATTON\, Graham (Cambridge Web Development)\nF ormEncode is the form data validation library included by default with bot h TurboGears and Pylons.

Especially the ZCML configuration language and the missing Python API for configurati on actions seems to be an obstacle for Python programmers.\n\nThe talk int roduces bebop.protocol\, an experimental package that tries to combine the conciseness of Python with the explicitness\, fine-grained configurabilit y\, and conflict management of ZCML. A protocol is a Python class that def ines how a component is configured\, registered\, called\, and unregistere d. Protocols are used and extended by declarations\, i.e. class advisors a nd decorators that correspond to existing ZCML directives. All declaration s within a package can be activated with a single line of ZCML. The equiva lent ZCML configuration can be recorded for documentary purposes and used as a basis for more selective configurations and overrides.\n\nIn comparis on to Grok\, which tries to simplify Zope3 by using conventions instead of ZCML\, Bebop favors a less radical approach. Grok smashes ZCML\, Bebop ge nerates ZCML. Since the protocol package mimics the ZCML directives as clo sely as possible it provides no extra learning curve for the experienced Z ope3 programmer. Predefined protocols are available for adapters\, utiliti es\, subscribers\, pages\, and menus. Since protocols are extensible\, the y can also be used to define generic functions and extend the component ar chitecture with special forms of utilities and adapter lookup. The zope.fs sync package is used as an example that illustrates how existing code coul d benefit from protocols. Relationships to PEP 3124 and other proposals ar e also discussed.\n\nBebop Protocols: http://svn.kmrc.de/projects/devel/be bop.protocol/trunk/src/bebop/protocol/README.txt\n\nhttp://indico.cern.ch/ contributionDisplay.py?contribId=38&sessionId=19&confId=13919 LOCATION:Vilnius\, Lithuania Zeta URL:http://indico.cern.ch/contributionDisplay.py?contribId=38&sessionId=19 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:How our Python trading platform got 40 times faster by switching t o RPython DTSTART;VALUE=DATE-TIME:20070710T073000Z DTEND;VALUE=DATE-TIME:20070710T080000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-33@cern.ch DESCRIPTION:Speakers: Mr. BURTON\, Simon (EWT LLC.)\, Mr. EMSLIE\, Richard (???)\nAt EWT we develop systems that trade stocks on the electronic exch anges.\nThe idea is that a computer can augment a human trader's reflexes by\nresponding to market movements on the millisecond timeframe.\n\nThis y ear we made the transition from python to rpython.\nWe found that not only is our turnaround much faster\nbut the code itself is able to be cleaned up as\nperformance critical hacks are not needed anymore.\n\nRPython: it's here\, it's useable in real world situations\, and it really rocks. \n\nR Python feels like writing C (C++/C#/Java) code in python.\nSince it is alm ost entirely a subset of python\nit's like being able to run dangerous C c ode in the safe confines of\na python interpreter.

DTSTART;VALUE=DATE-TIME:20070710T080000Z DTEND;VALUE=DATE-TIME:20070710T083000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-32@cern.ch DESCRIPTION:Speakers: Mr. GRAZ\, Michael (ITG London)\nWith the recent add ition of the win32console module in python it is now possible to create GU I applications that have embedded console sessions. The win32console modu le is a wrapper around the Microsoft Windows console API which is the oper ating system component that enables character-mode applications to display data to a windows console. The most typical console mode application on Windows is the cmd.exe command line interpreter. By utilizing the capabil ities of the win32console module\, it is now possible to embed and enhance routine command line/shell interactions by the use of GUI applications. Examples of embedding cmd.exe sessions would be:\n - wxPython based she ll acting as a console replacement\n - Divmod Nevow web pages using "se rver-push/comet" technologies as an interface around a remote console sess ion\n - cmd.exe session running in a Vim buffer\n\nIt is not only cmd.e xe that can be embedded but any other character-mode applications such as a Cygwin shell or even the python or iPython interpreters.\n\nThe basic pr ocess flow is described as:\n - Client process (1) such as wxPython or Vim editor starts an intermediary control process (2).\n - The intermed iary control process (2) is a child python process which imports win32cons ole and allocates its own private console.\n - This control process (2) then starts the target character-mode application (3) such as cmd.exe or python.exe.\n - The control process (2) installs WinEventHook functions which are triggered whenever the target process (3) or any child processe s of the target process write text to the console of the control process.\ n - The control process (2) traps the console output and then relays it the client process (1) by means of shared memory and event synchronizatio n.\n - The client process (1) can also generate command line input via shared memory to the control process (2) which then writes it into the inp ut buffer of the target process (3).\n\nFrom the perspective of the wrappe d console process (cmd.exe or python.exe interpreter for example) there is nothing to distinguish its input as coming from an interprocess communica tion mechanism versus a person typing on a keyboard. Likewise there is no thing different in the output statements of the wrapped console process si nce it is just doing standard console output. The use of the win32console module wrapping the Windows console API simplifies interaction with the c onsole processes since they will be running in their native command-line m ode with no modifications required.\n\nTechnical discussion with slides an d demonstrations will be presented.\n\nhttp://indico.cern.ch/contributionD isplay.py?contribId=32&sessionId=20&confId=13919 LOCATION:Vilnius\, Lithuania Alpha URL:http://indico.cern.ch/contributionDisplay.py?contribId=32&sessionId=20 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:What Zope did wrong (and what to do instead) DTSTART;VALUE=DATE-TIME:20070711T073000Z DTEND;VALUE=DATE-TIME:20070711T083000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-31@cern.ch DESCRIPTION:Speakers: Mr. REGEBRO\, Lennart (Colliberty)\nZope was an earl y web framework\, and one of the first complete\nframeworks to include suc h things as persistance\, security management\nand extensibility.

It contains a number of compone nts that help developers provide WebDAV support for their application.\n\n z3c.dav works by parsing all the WebDAV requests. It then uses the Zope co mponent architecture to lookup a WebDAV component that can handle the data it just received. This component may get or set the value of a property\, or it can call on other components from the Zope3 framework to perform th e requested action. Locking\, copy and move are implemented this way. Thes e WebDAV components do not deal with parsing of the request data nor do th ey deal with generating any possible response\, they just handle the data according to the WebDAV components contract and z3c.dav will handle the re st of the protocol details.\n\nThis design as meant that z3c.dav can suppo rt multiple content types to varying degrees within the one application. I n the future I am planning to build on z3c.dav to support extensions to th e WebDAV protocol like search\, access control lists\, and calendaring.\n\ nThis talk will introduce the project and the features it supports. I will then cover all the common components implemented in z3c.dav that a develo per will need in order to provide WebDAV support for their application. I will then demonstrate this with a sample application using OpenOffice.org as a client. Finally I will give a outline for the future of this project. \n\nhttp://indico.cern.ch/contributionDisplay.py?contribId=30&sessionId=19 &confId=13919 LOCATION:Vilnius\, Lithuania Theta URL:http://indico.cern.ch/contributionDisplay.py?contribId=30&sessionId=19 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:PyPy 1.0 and Beyond DTSTART;VALUE=DATE-TIME:20070709T120000Z DTEND;VALUE=DATE-TIME:20070709T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-37@cern.ch DESCRIPTION:Speakers: Mr. PEDRONI\, Samuele (Open End AB)\, Mr. RIGO\, Arm in (PyPy)\nPyPy released 1.0 in March of this year.

It is distributed\nand co mponent-based: every step in the streaming process (production\,\nconversi on\, consumption) can be run inside a separate process on separate\nmachin es.\n\nFlumotion uses Twisted and GStreamer. Twisted enables the high-leve l\nfunctionality\, distributing components over the network. GStreamer\, t hrough the\nPython bindings\, enables the high-speed low-level functionali ty: actual media\nprocessing.\n\nFlumotion uses a central manager process to control the complete network\; one\nor more worker processes distribute d over machines to run actual streaming\ncomponents\; and one or more admi n clients connecting to the manager to control\nit.\n\nFlumotion is under very active development. In its latest stable release\n(0.4.2)\, it alread y supports the following features:\n\n- various sources: webcams\, soundca rds\, TV cards\, Firewire cameras\, looper\n- various codecs: Vorbis\, The ora\, mulaw\, JPEG\, smoke\n- various containers: Multipart\, Ogg\n- synch ronized capturing across machines\n- username/password authentication\n- o verlaying\, colorbalance\n- HTTP streaming\, disk archiving\n- administrat ion GUI with a wizard for the most basic scenario\n- ncurses-based adminis tration\n- code distribution from a central location\n- local caching of t he distributed code space\n- strong focus on ease of use and usability\n- improved support for network failure and reconnection\n- multiplex all com ponent feeds through only one port on the worker\n- sharing HTTP port amon g streamers\n- support for GStreamer 0.10\n\nThe current design allows for the following future features:\n\n- any number of sources/containers/code cs/effects/protocols to be added\n- completely centralized code upgrades\n - complete code upgrades with minimal downtime\n- any kind of authenticati on mechanism (key exchange\, challenge/response\, ...)\n- any number of po ssible scenarios for actual content production and\n distribution\n- mana ger failover and state replication\n- loadbalancing streams over different servers or from different locations\n- internal stresstests\n\nSome of th e features are only possible or easily implementable thanks to using\na hi gh-level language like Python:\n\n- sending GUI code for the wizard and co mponent administration from the manager\n to the admin client\, making th e admin GUI a lightweight shell\n- sending component code to any of the wo rkers over the wire at startup\n- rebuilding modules and reloading code on the fly while running\; allowing for\n a distributed code upgrade withou t losing clients\n- rapid development of new components\, allowing to catc h up with and eventually\n to keep one step ahead of the competition\n- e asy networking code thanks to Twisted\n\nIn this project\, we came up with solutions to specific problems presented to us\nthat would be interesting to share with others.\n\n- all code is stored centrally and partitioned i nto "bundles" which are cached\n by clients who need them. Versioning and dependencies are correctly handled\,\n and to the code being run this is handled transparently. Code can still\n import as if it were one big fil e tree.\n\n- the manager sends GUI code to an admin client and component c ode to a worker.\n The GUI code running on the admin machine then control s the behaviour of code\n running on the worker machine by going through the manager machine\n\n- state of components is automatically replicated o ne level deep to the\n manager\, and two levels deep to all connected adm in clients\n\n- authentication of any service in the network is handled by creating keycards\n which can be exchanged between all processes\, imple menting any type of\n challenge/response authentication as securely as po ssible.\n\n- Twisted's Perspective Broker was extended to use this generic keycard concept\n instead of the current (limited) username/password cre dentials.\n\n- the open-ended nature of Twisted and GStreamer is difficult to harness into a\n usable GUI. The wizard provides a good way of crysta llizing all possibilities\n into a sensible task-based presentation. The design of the wizard also\n incorporates the flexibility of the network d istribution and the dynamic code\n distribution by pulling in the necessa ry GUI code for the next step based on\n previous choices.\n\n- moving to run-time checks of functionality as opposed to\n compile/configure-time. Since the server can be distributed over any number\n of machines\, and actual components have different run-time needs\, all checks\n for featur es (devices\, required libraries\, versions\, permissions)\n\nPython also presents some specific challenges when used in a large project as\ncompare d to more low-level languages. When handled right\, these can actually be\ nturned into project engineering advantages. Python's weak argument typing \nforces developers to document the API correctly. Python's dynamic nature \n(running code from received chunks\, extensive subclassing) and Flumotio n's\ndesign (componentized functionality\, lots of small pieces of code se nt back and\nforth) forces us to aggressively write unit testing for all f unctionality.\n\nhttp://indico.cern.ch/contributionDisplay.py?contribId=63 &sessionId=20&confId=13919 LOCATION:Vilnius\, Lithuania Theta URL:http://indico.cern.ch/contributionDisplay.py?contribId=63&sessionId=20 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Pythonic Math DTSTART;VALUE=DATE-TIME:20070709T120000Z DTEND;VALUE=DATE-TIME:20070709T123000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-64@cern.ch DESCRIPTION:Speakers: \nMy paper for EuroPython 2005 explored what I call Pythonic Mathematics\,\na way of presenting pre-computer analytical conten t within the OO\nparadigm\, including pre-college.[1] This thinking infor med my\nparticipation in Shuttleworth Foundation planning meetings and\npr esentation to the London Knowledge Lab in the following year.[2]\n\nThis y ear\, I'm delving yet more deeply into Pythonic Math\, while also\nweaving in some more cultural threads\, especially the "design science"\nthread w ith its geodesic spheres and other graphical content\, the\ntheme of my OS CON 2005 presentation.[3] I've been field testing\nthese combinations in my home town of Portland\, through a school\ncalled Saturday Academy.[4]\n \nWhereas Guido named Python for Monty Python\, begetting allusions\nwhich aren't going to go away\, there's more we might do to make our\nsnake com e across as charming and smooth\, not too slimy or oily\n(negative attribu tes customarily associated with snakes by the\nmore snake-unfriendly).[5]\ n\n[1] http://www.4dsolutions.net/presentations/urner_europython4.pdf\n[2] http://www.bfi.org/bfi_community/pythonic_mathematics_talk_by_kirby_u\nrn er\n[3] http://worldgame.blogspot.com/2007/01/reviewing-my-oscon-2005-talk .ht\nml\n[4] http://www.saturdayacademy.org/\n[5] http://worldgame.blogspo t.com/2007/06/pro-python-propaganda.html\n\nhttp://indico.cern.ch/contribu tionDisplay.py?contribId=64&sessionId=21&confId=13919 LOCATION:Vilnius\, Lithuania Zeta URL:http://indico.cern.ch/contributionDisplay.py?contribId=64&sessionId=21 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Keynote by Simon Willison DTSTART;VALUE=DATE-TIME:20070709T154500Z DTEND;VALUE=DATE-TIME:20070709T164500Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-67@cern.ch DESCRIPTION:Speakers: Mr. WILLISON\, Simon ()\nhttp://indico.cern.ch/contr ibutionDisplay.py?contribId=67&sessionId=26&confId=13919 LOCATION:Vilnius\, Lithuania Alpha URL:http://indico.cern.ch/contributionDisplay.py?contribId=67&sessionId=26 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Arlo Belshee: Safe Is For Weenies DTSTART;VALUE=DATE-TIME:20070710T120000Z DTEND;VALUE=DATE-TIME:20070710T123000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-68@cern.ch DESCRIPTION:Speakers: Mr. BELSHEE\, Arlo ()\nhttp://indico.cern.ch/contrib utionDisplay.py?contribId=68&sessionId=29&confId=13919 LOCATION:Vilnius\, Lithuania Alpha URL:http://indico.cern.ch/contributionDisplay.py?contribId=68&sessionId=29 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Arlo Belshee: Agile Adoption DTSTART;VALUE=DATE-TIME:20070710T123000Z DTEND;VALUE=DATE-TIME:20070710T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-69@cern.ch DESCRIPTION:Speakers: Mr. BELSHEE\, Arlo ()\nhttp://indico.cern.ch/contrib utionDisplay.py?contribId=69&sessionId=29&confId=13919 LOCATION:Vilnius\, Lithuania Alpha URL:http://indico.cern.ch/contributionDisplay.py?contribId=69&sessionId=29 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Managing and displaying user track data with Python DTSTART;VALUE=DATE-TIME:20070710T130000Z DTEND;VALUE=DATE-TIME:20070710T133000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-2@cern.ch DESCRIPTION:Speakers: Mr. APRILE\, Walter (Scuola Superiore Sant'Anna)\nUs er studies that feature user movement in the real world or in simulated en vironment\ngenerate datasets\, usually in the form of logfiles\, that need to be stored\,\nsummarized\, processed and represented.

One way to deal with this increased complexity is through the use of software libraries. Many object-oriented languages p rovide special constructs such as abstract classes and interfaces which en sure that components are properly extended and executed. Unfortunately\, t he Python programming language is devoid of such features. In this article \, we present a library extension for Python to include these features int o the language and allow for explicit class interfaces and abstract classe s. While it has been attempted before\, our library provides a simple\, e legant\, and Pythonic solution to the problem via a pure-Python stand-alon e library. By extending the Python language in this manner\, we allow dev elopers to define concrete models for libraries and create modular code\, while ensuring that software system designs are enforced at run time. We a lso argue that this provides the Python language another degree of flexibi lity in a formalized mechanic\, as opposed to error-prone traditional “h and-shake” contracts. The usability of our proposed Python extension is demonstrated in a case study of an original game engine framework.\n\nhttp ://indico.cern.ch/contributionDisplay.py?contribId=44&sessionId=20&confId= 13919 LOCATION:Vilnius\, Lithuania Theta URL:http://indico.cern.ch/contributionDisplay.py?contribId=44&sessionId=20 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:unittest is Broken DTSTART;VALUE=DATE-TIME:20070709T143000Z DTEND;VALUE=DATE-TIME:20070709T150000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-45@cern.ch DESCRIPTION:Speakers: WINTER\, Collin (Google)\nIn this paper I examine th e shortcomings and core design flaws of Python's standard unittest module\ , focusing specifically on the programmer's ability to extend unittest.

Our graphi cs server\, also written in Python\, created the dials and\ncharts in real -time.\n\nhttp://indico.cern.ch/contributionDisplay.py?contribId=9&session Id=27&confId=13919 LOCATION:Vilnius\, Lithuania Theta URL:http://indico.cern.ch/contributionDisplay.py?contribId=9&sessionId=27& confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Open Space DTSTART;VALUE=DATE-TIME:20070709T090000Z DTEND;VALUE=DATE-TIME:20070709T103000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-77@cern.ch DESCRIPTION:Speakers: \nhttp://indico.cern.ch/contributionDisplay.py?contr ibId=77&sessionId=23&confId=13919 LOCATION:Vilnius\, Lithuania Lambda URL:http://indico.cern.ch/contributionDisplay.py?contribId=77&sessionId=23 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Open Space DTSTART;VALUE=DATE-TIME:20070709T070000Z DTEND;VALUE=DATE-TIME:20070709T083000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-76@cern.ch DESCRIPTION:Speakers: \nhttp://indico.cern.ch/contributionDisplay.py?contr ibId=76&sessionId=23&confId=13919 LOCATION:Vilnius\, Lithuania Lambda URL:http://indico.cern.ch/contributionDisplay.py?contribId=76&sessionId=23 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Arlo Belshee: The XP Sprint DTSTART;VALUE=DATE-TIME:20070711T090000Z DTEND;VALUE=DATE-TIME:20070711T100000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-75@cern.ch DESCRIPTION:Speakers: \nhttp://indico.cern.ch/contributionDisplay.py?contr ibId=75&sessionId=29&confId=13919 LOCATION:Vilnius\, Lithuania Alpha URL:http://indico.cern.ch/contributionDisplay.py?contribId=75&sessionId=29 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Arlo Belshee: The XP Sprint DTSTART;VALUE=DATE-TIME:20070711T073000Z DTEND;VALUE=DATE-TIME:20070711T083000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-74@cern.ch DESCRIPTION:Speakers: \nhttp://indico.cern.ch/contributionDisplay.py?contr ibId=74&sessionId=29&confId=13919 LOCATION:Vilnius\, Lithuania Alpha URL:http://indico.cern.ch/contributionDisplay.py?contribId=74&sessionId=29 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Arlo Belshee: Promiscuous Pairing DTSTART;VALUE=DATE-TIME:20070711T070000Z DTEND;VALUE=DATE-TIME:20070711T073000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-73@cern.ch DESCRIPTION:Speakers: \nhttp://indico.cern.ch/contributionDisplay.py?contr ibId=73&sessionId=29&confId=13919 LOCATION:Vilnius\, Lithuania Alpha URL:http://indico.cern.ch/contributionDisplay.py?contribId=73&sessionId=29 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Keynote by David Axmark DTSTART;VALUE=DATE-TIME:20070711T120000Z DTEND;VALUE=DATE-TIME:20070711T130000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-72@cern.ch DESCRIPTION:Speakers: Mr. AXMARK\, David ()\nhttp://indico.cern.ch/contrib utionDisplay.py?contribId=72&sessionId=26&confId=13919 LOCATION:Vilnius\, Lithuania Alpha URL:http://indico.cern.ch/contributionDisplay.py?contribId=72&sessionId=26 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Keynote by Guido van Rossum DTSTART;VALUE=DATE-TIME:20070710T151500Z DTEND;VALUE=DATE-TIME:20070710T161500Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-71@cern.ch DESCRIPTION:Speakers: Mr. VAN ROSSUM\, Guido ()\nhttp://indico.cern.ch/con tributionDisplay.py?contribId=71&sessionId=26&confId=13919 LOCATION:Vilnius\, Lithuania Alpha URL:http://indico.cern.ch/contributionDisplay.py?contribId=71&sessionId=26 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Arlo Belshee: Appraising The Loot DTSTART;VALUE=DATE-TIME:20070710T130000Z DTEND;VALUE=DATE-TIME:20070710T133000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-70@cern.ch DESCRIPTION:Speakers: Mr. BELSHEE\, Arlo ()\nhttp://indico.cern.ch/contrib utionDisplay.py?contribId=70&sessionId=29&confId=13919 LOCATION:Vilnius\, Lithuania Alpha URL:http://indico.cern.ch/contributionDisplay.py?contribId=70&sessionId=29 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Open Space DTSTART;VALUE=DATE-TIME:20070709T130000Z DTEND;VALUE=DATE-TIME:20070709T133000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-79@cern.ch DESCRIPTION:Speakers: \nhttp://indico.cern.ch/contributionDisplay.py?contr ibId=79&sessionId=23&confId=13919 LOCATION:Vilnius\, Lithuania Zeta URL:http://indico.cern.ch/contributionDisplay.py?contribId=79&sessionId=23 &confId=13919 END:VEVENT BEGIN:VEVENT SUMMARY:Open Space DTSTART;VALUE=DATE-TIME:20070709T120000Z DTEND;VALUE=DATE-TIME:20070709T133000Z DTSTAMP;VALUE=DATE-TIME:20130524T104354Z UID:indico-contribution-13919-78@cern.ch DESCRIPTION:Speakers: \nhttp://indico.cern.ch/contributionDisplay.py?contr ibId=78&sessionId=23&confId=13919 LOCATION:Vilnius\, Lithuania Lambda URL:http://indico.cern.ch/contributionDisplay.py?contribId=78&sessionId=23 &confId=13919 END:VEVENT END:VCALENDAR
