Michael Kay develops the Saxon XSLT and XQuery processor for manipulating XML; he is the founder of Saxonica, which develops and licenses both the open source and commercial versions of the product. Both versions have a large user base, including many high-throughput and high-profile applications especially in publishing and financial services. As an open source project there are probably two distinctive features worth noting about Saxon: the fact that the software (200K lines of code) is almost entirely developed by one person, and the successful use of a dual-licensing business model. Before starting the development of Saxon ten years ago, Michael was an ICL Fellow, having spent nearly 25 years with ICL as a software product designer and in a variety of other systems architecture and senior engineering roles. As well as developing Saxon, he is editor of the W3C XSLT language specification, and has written the definitive book on the language. He is a frequent conference speaker, and his contributions to the XML community were recognized in 2005 by the award of the XML Cup.

He is also a developer of Open Source software including contributions to a number of projects and he helps to run the PyConUK and EuroPython Python programming language conferences.


OSS-Watch TransferSummit – Oxford, 24-25/06/10

TransferSummit, Oxford, 24-25 June 2010 This summer, OSS Watch is sponsoring a major open source conference, aiming to connect academia with open source businesses.  The main conference will be held over two days, 24-25 June 2010, at Keble College Oxford. Covering topics within both academia and business, the event will try to identify areas of activity of mutual interest, looking at how the two sectors can engage with each other. Registration is now open.

OSS-Watch BarCamp – Oxford 26/06/10

BarCamp Oxford, 26 June 2010 [Wed, 28 Apr 2010 10:32:49 +0100] OSS Watch has teamed up with Torchbox to run a BarCamp at the Oxford University Club in Oxford in 26 June 2010. In keeping with the concept of a BarCamp this is an informal, geeky event where delegates can set their own agenda for discussions. This BarCamp follows on from the TransferSummit taking place in Oxford over the previous few days so we hope to see some of the conference delegates staying on for the BarCamp but you don’t need to have been to the conference to join in the fun. Why not sign up today!

Open Source in Telecommunications – London 22/04/10 1

The telecommunications industry has a deep and complex history, where proprietary technologies have featured heavily, the barrier to entry has typically been high and the majority of research and development led by incumbent network operators and equipment providers. More recently we are seeing this change with the growing popularity of IP telephony, the availability of open source softswitch implementations and the aggressive adoption of Linux in mobile handsets, home router/gateways and other customer-premises equipment (CPE). However, whilst the opportunities are significant, many challenges to open source adoption remain and the telecoms environment presents its own set of unique problems.

The BCS Open Source Specialist Group has joined forces with BT to bring an event that seeks to provide insights into the state of the art of open source in telecommunications. The event will consist of a series of talks followed by a panel-led, open discussion centred upon the opportunities that exist and the challenges that the telecommunications industry and open source community faces.

The event will be held at the BCS Central London Offices, First Floor, The Davidson Building, 5 Southampton Street, London WC2E 7HA (http://www.bcs.org/upload/pdf/london-office-guide.pdf) on Thursday 22nd April, 2010, from 10.00 to 17.30.

To book a place at this event, which is free and open to all, please contact Mark Elkins via mark_elkins@bcs.org

Agenda

10:00 Introduction

10:15 Why would BT care about Open Source? Jeremy Ruston (BT)

With organisations the size of the BT, you frequently hear announcements that they have partnered with a vendor or done a major deal with a service provider. Large figures are often mentioned – such as the size of a market, the number of users involved or simply the value of a contract. But what about software that is developed by communities of interest, where no vendor may be involved and no money changing hands?

In this presentation Jeremy Ruston will explain what open source means to BT and what drove them to acquire Osmosoft, a small software development company focused on producing open source, web-based collaboration technology. Reflecting on three years as BT’s Head of Open Source Innovation, he will provide an insight into the evolving technology landscape at BT, and outline the key role that open source software has to play in BT’s future.

10:45 Vyatta – open source, software-based enterprise-class IP routing. Ben King (Net That Works)

  • Why Vyatta?
  • Vyatta vs. Cisco – A real world comparison
  • Vyatta – Too big to be small, too small to be big?
  • Vyatta – What are the limits?

11:15 Break

11:30 But you can’t get support for Open Source, can you? Mark Taylor (Sirius)

One of the favourite anti-Open Source myths of proprietary software companies is that Open Source is unsupported and that there’s nobody to turn to for your organisations needs. Mark’s talk will reveal this FUD (‘Fear, Uncertainty, Doubt’) as the nonsense that it is, and show exactly how organisations using Open Source, the support ecosystem, and the underlying projects themselves interact to provide a level of support for Open Source software in the enterprise that simply can’t be matched by the old-school proprietary software vendors.

Using detailed case studies, anecdotes and over a decades experience on the front-lines of Open Source uptake, this talk will give you the information you need to know to confidently deploy enterprise-class Open Source in your own organisation.

12:00 Open Source in Mobile. Andrew Savory (LiMo Foundation)

The LiMo Foundation are building a mobile middleware stack based on Linux. With over 70% of the platform based on open source components, what are the benefits and challenges of open source adoption, and what is the LiMo approach to working with Open Source?

12:30 Open Source, Standards and Standardisation. Paul Downey (BT)

Building on a previous, deliberately provocative talk on “Standards are Peace as Standardization is to War”[1] and an address on Web 2.0 given to the ETSI Board[2] Paul will present a short guide for

assessing the likely impact of the culture of Open Source and lightweight agreements made on The Web on the formal Telecoms standards and standardization process.

13:00 Lunch

13:45 Ensuring Mobile Internet Connectivity at T-Mobile with Nagios. Bernd Erk (Netways)

Since 2003, T-Mobile has employed open source software alongside the traditional close source products. For the last few years, NETWAYS has supported T-Mobile in the deployment and scaling of their Nagios system. Over this period, not only was the in-house company network integrated into the system, but also the international data roaming on GSM networks was established and continuously expanded. This presentation will share the development of T-Mobile’s open source monitoring system to monitor its entire GSM network and data transfer (roaming) to ensure the highest availability of over 450 foreign GSM networks.

14:15 Asterisk. Antony Stone (Sirius)

Asterisk is an Open Source computer-based telephony project which enables the creation of software-based PABX systems, VoIP gateways, call centres and many other computer-telephony integrated applications.  The software supports interfaces to both analogue and digital telephones and exchange lines, and provides features such as intelligent routing, call queuing, music on hold, conference calling and voicemail.  Plugin applications provide integration with standard database servers, corporate directory servers, text-to-speech and voice recognition systems.  Asterisk enables commodity PC hardware to be used for multi-user multi-site voice communications, including connectivity to legacy telephone systems such as analogue phone lines and ISDN.

14:45 Building a GSM Network with OpenBTS. Tim Panton (Westhawk)

OpenBTS is an open-source Unix application that uses the Universal Software Radio Peripheral (USRP) to present a GSM air interface (“Um”) to standard GSM handset and uses the Asterisk software PBX to connect calls. The combination of the ubiquitous GSM air interface with VoIP backhaul forms the basis of a new type of mobile network that can be deployed and operated at substantially lower cost than existing technologies in greenfields in the developing world.

In plain language, OpenBTS lets you create new kind of mobile network that can be installed and operated at about 1/10 the cost of current technologies, but that will still be compatible with most of the handsets that are already in the market. This technology can also be used in private network applications (wireless PBX, rapid deployment, etc.) at much lower cost and complexity than conventional mobile.

This talk will cover the experience and lessons learnt from a recent trial deployment on the pacific island of Niue.

15:15 Break

15:30 PostgreSQL in Telecommunications. Simon Riggs (2ndQuadrant)

PostgreSQL has a variety of features of interest to Telco users. Many well known companies are already users and a brief review of deployed solutions gives a flavour of that. Enhancements in PostgreSQL 9.0 due out in mid-2010 will also be discussed, plus further developments in later releases.

16:00 OpenNMS and the Telemanagement Forum Standardisation Activities. Dr Craig Gallen (OpenNMS)

OpenNMS is the worlds first enterprise grade Open Source Network Management platform. Unlike other Open source Network Management tools, OpenNMS has been designed specifically with the scalability and enterprise integration requirements of large telecommunications operators in mind. It and is being used in production by a number of large service providers.

In order to continue to address the requirements of the telecommunications industry, OpenNMS has been contributing to the TM Forum Interface Program which is standardizing the next generation of OSS interfaces. One of the most innovative aspects of the program is in its use of Open Source development techniques and technologies to increase the attractiveness of the new interfaces for early adopters. Open source is being used to create the core Interface Framework artefacts, Reference Implementations, Compatibility Test Kits and an Implementation library for prospective developers.

This talk will provide an introduction to the OpenNMS project and it’s contribution to industry standardisation through the TM Forum.

Call for papers: OpenCert 2010

4th International Workshop on Foundations and Techniques for OPEN SOURCE SOFTWARE CERTIFICATION

Location and date
Pisa, Italy – 17-18 September 2010
Satellite Event to SEFM 2010
Website
http://opencert.iist.unu.edu/
Submission deadline
28 June, 2010

CONTEXT & OBJECTIVES

Over the past decade, the Open Source Software (OSS) phenomenon has had a global impact on
the way software systems and and software-based services are developed, distributed and deployed.
Widely acknowledged benefits of OSS include reliability, low development and maintenance costs,
as well as rapid code turnover. Linux distributions, Apache and MySQL serve, among many other examples,
as a testimony to its success and resilience.

However, state-of-the-art OSS, by the very nature of its open, unconventional, distributed
development model, make software quality assessment, let alone full certification, particularly
hard to achieve and raises important challenges both from the technical/methodological and
the managerial points of view.

This makes the use of OSS, and, in particular, its integration within complex industrial-strength
applications, with stringent security requirements, a risk. And, simultaneously an opportunity and
a challenge for rigourous, mathematically based, methods in software analysis and engineering.

In such a context, the aim of this workshop is to bring together researchers from academia and industry
who are broadly interested in the quality assessment of open source software projects, ultimately leading
to the establishment of coherent certification processes, at different levels.

Following the success of the three previous editions (colocated to ETAPS’07, in Braga, and OSS’08,
at IFIP WCC, in Milan, and ETAPS’09, in York), the workshop will focus on formal methods and
model-based techniques that appear promising to facilitate OSS certification.
Both foundational, methodological and pragmatic issues will be addressed, through both standard
technical communications and reports on concrete case-studies and experimental data.

CONTRIBUTIONS

Contributions are expected to foster a broad debate on OSS assessment and certification, integrating
techniques and elements from areas as different as

  • product and process certification
  • certification standards
  • formal modelling and verification (model checking and theorem proving)
  • software quality and reverse engineering
  • static analysis, testing and inspection
  • safety, security and usability certification
  • language design and evolving systems
  • automated source code analyses
  • empirical studies

SUBMISSION

The two-day workshop will feature invited talks, a pannel discussion and contributed
paper presentations. All contributions, in the form of either full technical papers,
between 10 and 16 pages, or short position papers, will undergo a peer-review process.
All papers should be written in English and in ECEASST format.

Detailed information on the submission procedure are available at http://opencert.iist.unu.edu/

PUBLICATION

Accepted papers will be published in Electronic Communications of the EASST (ECEASST)
Publication of selected papers in a journal is currently under negotiation.
