Anytime Anywhere Computing

Joss Winn / / Hardware, Mobile, Projects, Software

Together with the ITC Department, we’ve recently begun a feasibility study which looks at related areas of the university’s ITC provision. It brings together three, originally separate proposals to look at upgrading our wireless infrastructure, provide a more flexible desktop experience through virtualisation and improve our understanding of and support for Netbooks and Mobile Internet Devices. It’s good to be working so closely with our ITC Department. So often I hear people at other institutions complain about their ITC departments being ‘brick walls’ and showing no flexibility, but fortunately I can’t say that about my experience at the University of Lincoln.

The Head of ITC sent me a link to this video today. It’s a good example of why our study is both necessary and worthwhile.

Related to this, Tony Hirst recently bookmarked this ITC syllabus for 13-14 year olds recently, which, together with the video, provides a clear indication of what’s happening in schools.

We’re working closely with the Student Council and Academics and intend to survey them on the issues raised by the study early in the new year.  We’ve started talking to vendors of desktop and application virtualisation ‘solutions’, too (the virtualisation of our server infrastructure is almost complete). We’re also lining up some visits to other institutions that have experience in these areas.

If you or your school, your FE or HE insititution has seriously considered or implemented desktop and/or application virtualisation, a full service wireless infrastructure (i.e. it matches the services on your wired network) and support Linux and XP-based Netbooks and other mobile devices, please do get in touch or leave a comment below.

OpenSim Virtual World

Joss Winn / / Learning Landscapes, Open Source, Software

Following my initial local install of OpenSim, I now have it running on the Learning Lab server. It was a bit of a nuisance to install and I still need to look at how best to work with its seemingly basic user management, but for alpha software it seems pretty stable and worth investing some time in. I’ve set up a page on our wiki to document the process.

I was first introduced to OpenSim by Ian Truelove at Leeds Met, who ran an introductory workshop to Second Life using OpenSim. He uses private installs of OpenSim with his students to teach design for virtual worlds, a genuine occupation for some. At least one academic here, who teaches 3D animation, wants to experiment with it and as I tell more people, I’m sure there will be further interest. My colleague, Julian, has also blogged about Second Life recently.

I’ve also been asked to write a Briefing Paper for the university’s next Learning Landscapes Working Group meeting, on how virtual worlds could extend the overall ‘learning landscape’ and benefit the student experience. It’s not a subject I know a great deal about (except for an intense period with Doom II while writing my MA dissertation, my gaming period ended with Elite), but there have been some useful and interesting reports recently, which I will look at again.

These days are full

I am conscious that it’s been almost a month since I last wrote here but that is largely due to my work on other projects, websites and blogs.  Here’s an overview of some of the work I’m currently involved in. If you’re working on similar projects or want to discuss or collaborate on any of this, do get in touch.

The Learning Lab

I recently wrote a brief summary of the work I’ve been doing under the ‘Learning Lab’ banner, since I started my work as Technology Officer in the Centre for Educational Research and Development. WordPressMU occupied a large chunk of my summer, though I feel I have a good understanding of it now and can relax a little while supporting staff and students who wish to use it. It will soon be moving to the new, permanent home of http://blogs.lincoln.ac.uk

One of the unexpected outcomes of working on WordPressMU was the realisation that not only training but a different model of support is key to sustaining and improving the use of blogs and other Web 2.0 tools.  I’m keen to advocate and support the user-to-user support model that most open source and social web services develop rather than the traditional user-to-professional, ‘Help Desk’ model that exists for much of the software provided by the university. Models of user support are not something I’ve taken much of an interest in until recently, but the reality is that I alone am unable to support the growing adoption of WordPressMU at the university and I need to encourage staff and students to help themselves wherever possible.

Having said that, with colleagues in the Library and Research Office, I’m also planning to offer regular staff training sessions on the use of Web 2.0 tools in education and I’m visiting classes to give one hour introductions to WordPress, which is a good opportunity to work with and learn from both students and staff. In addition to this, I’m contributing towards the revision of policy documents which ensure that these new tools are used effectively and appropriately.

Lincoln Academic Commons

This is something I’m developing to promote and support the various initiatives at the university which provide Open Access to our research, teaching and learning. I started working for the university on a JISC-funded project to develop an institutional repository, having been working as an Archivist and Project Manager of a Digital Asset Management system in my previous job. Then, a few months ago, I heard about the difficulties people in the Lincoln Business School were having trying to establish a series of ‘Occasional Working Papers’ (OWPS) using existing portal software provided by the university. At the same time, I was looking at the Open Journal System for publishing Open Access journals, so I suggested that we set up the OWPS using OJS. Seeing what a great piece of software OJS is, I then suggested we use it for NEO, a planned journal of student research which we intend to launch in the Spring. Finally (and this is where it gets really interesting for me), Mike Neary, Dean of Teaching and Learning and Head of the Centre for Educational Research and Development, is advocating a more critical engagement with the debates about the marketisation of higher education through teaching practice. He’s calling this critical engagement, ‘Teaching in Public’, which encompasses the idea of an Academic Commons.

Professor Neary argues the uncertainty over the university’s mission requires the notion of ‘the public’ to be reconceptualized, so as to remake the university as an academic project that confronts the negative consequences of academic capitalism, and the commodification of everyday life. He will present Karl Marx’s concept of the ‘general intellect’ as an idea through which the university might be remade.

I contributed to a book chapter Mike has recently written which elaborates on this in more detail. You can read more about that on a previous blog post.

Access Grid

A project I’ve been leading for some months now is the installation of an Access Grid node at the university. We were fortunate in being approached by the Mental Health Research Network (MHRN) several months ago who offered to fund the installation of an AG node at the university to support their staff who work at the university and provide a facility that is otherwise missing in Lincolnshire. It’s been a really interesting and useful project for me as I learned about how the university undertakes a tendering exercise and I’ve been able to work with colleagues from across the university.  The node should be available to use sometime in January. The Access Grid project is yet another technology-based initiative at the university which further improves our research infrastructure and supports collaboration and the wider exchange of ideas among colleagues worldwide.

Anytime, Anywhere Computing

This is a new project that brings together three, originally separate proposals, that the ICT department and CERD were proposing to take forward. It covers:

  1. ubiquitous wireless networking
  2. so called ‘thin client’ technology as an alternative to desktop PCs and the management of software applications and resources
  3. access via user-owned devices, such as low-cost and increasingly popular ‘netbook’ hardware

We’re just starting to look at how we might offer the same user experience and services on our wireless network as we provide on our wired network. Currently the wireless network only offers Internet access. At the same time, we’re interested in evaluating new virtualisation technologies for the desktop. The ICT department are concluding a server consolidation project which is virtualising much of our server infrastructure. This brings many benefits and allows the ICT department to provide a more flexible service to users.  Our new study will look at whether similar virtualisation technology can bring benefits to desktop users, too. The third part of this project is based on a proposal I made a few months ago to evaluate the user experience and support issues that the new generation of ‘netbooks‘ introduces. Smaller screens, Linux operating systems, an emphasis on web-based applications and the rapid adoption of these low-cost devices often aimed at the education sector, require a better understanding of the impact of this technology and the influence it may have on driving students to use more and more web-based applications.

Are you working on similar initiatives? If so, please leave a comment and share your experiences.

More like a web application and less like a website

Joss Winn / / Open Source, Software

Automattic, the company behind WordPress, released a report today which summarises their recent project to test the usability of WordPress. It’s an interesting read if you use WordPress, but also if you’re interested in software development and usability testing. What’s most interesting for me, is how a large and successful open source project can co-ordinate a major redesign of an application, tested by thousands of enthusiasts for use by millions of general users.

While discussions about the design of an open source application can be had at any time on support forums, in this case, the formal change process began in May, through focused third-party usability testing, where 12 volunteers were carefully selected (and paid $75 in wordpress.com credits!). There was then a presentation at the San Francisco WordCamp in August, where wider feedback was elicited. A survey was announced in early September and a further survey, calling for 5000 participants was announced in late September. An annoucement was made at the beginning of October, where feedback was invited on a series of ‘wireframe’ mockups of the new design. Following feedback, the re-design was formally announced in mid-October and later this month designers were asked to submit their portfolio if they were interested in being recruited to design new icons (the following week!). Throughout this process, the development code, updated nightly, could be downloaded, installed and the application reviewed, too. Several mailing lists are used for open discussion, notably the ‘hackers’ and ‘testers’ lists.

The outcome of this incredibly rapid and completely transparent consultation, testing, feedback and design process has made it into the next release of WordPress (v2.7), due for release on November 10th. At just seven months from start to finish, it’s an excellent example of public collaboration between developers, designers and users, largely co-ordinated by one Automattic employee.

Here’s the testing report (PDF)

Here’s the presentation they gave in August, which covers the usability testing process.

UK WordCamp (Ed)ucation?

Joss Winn / / Conferences, Fun, Learning Landscapes, Software, Web

Having heard about the WordCamp Ed event in Washington DC, I’m thinking of organising a WordCamp, focussing on the use of WordPress in HE and FE in the UK.  Would anyone be interested in helping with the organisation of this? 

There is some support for organising WordCamps from Automattic. A lot of the items listed there would be easy to facilitate with support from one of our institutions.  I’d be happy to ask the University of Lincoln. We’re just off the main North-South East Coast rail trunk, but the access isn’t bad from London up to Edinburgh, and it’s a good, modern university, with decent facilities in a historic city worth visiting. 

I’m sure there would be a lot of interest in attending. It could appeal to teachers, students, researchers, ICT and web dev staff.  We could appeal for the involvement of edubloggers who have a lot of experience in advocating the use of blogs in HE and FE. 

There was a WordCamp in Birmingham in July 2008. We could contact the organisers of that event for advice as well as the organisers of the DC event.

The day might be organised like this: 

  • Registration and welcome
  • Keynote 
  • Live WordPressMU install and set up. A useful overview for both administrators and users. Also introduces the language of blogging which people will hear constantly throughout the day. i.e. ‘posts’, ‘pages’, ‘tags’, categories’, ‘blogroll’, ‘plugins’, ‘themes’, etc. 
  • Two or three presentations with Q&A on how people are using WordPress in education (maybe one from a marketing perspective, the others from a teaching and learning perspective) 
  • Lunch 
  • Keynote 
  • Special interest group sessions: research groups, teachers, students, marketing, administration, development, etc. 
  • Group feedback 
  • Presentation on forthcoming WordPress features. Integration of WP with other (social) services. Intro to BuddyPress and BBPress as extensions to WordPressMU.
  • Close

The Virtual Studio

Joss Winn / / Conferences, Open Access, Projects, Repositories, Software

I am in Venice to present a paper with two colleagues from the School of Architecture, at a two-day conference organised by the Metadata for Architectural Materials in Europe (MACE) Project. Yesterday was a significant day, for reasons I want to detail below. Skip to the end of this long post, if you just want to know the outcome and why this conference has been an important and positive turning point in the Virtual Studio project.

I joined the university just over a year ago to work on the JISC-funded LIROLEM Project:

The Project aimed to lay the groundwork for the establishment of an Institutional Repository that supports a wide variety of non-textual materials, e.g. digital animations of 3-D models, architectural documentation such as technical briefings and photographs, as well as supporting text based materials. The project arose out of the coincidental demands for the University to develop a repository of its research outputs, and a specific project in the school of Architecture to develop a “Virtual Studio”, a web based teaching resource for the school of Architecture.

At the end of the JISC-funded period, I wrote a lengthy summary on the project blog, offering a personal overview of our achievements and challenges during the course of the project. Notably, I wrote:

The LIROLEM Project was tied to a Teaching Fellowship application by two members of staff in the School of Architecture. Their intentions were, and still are, to develop a Virtual Studio which compliments the physical design Studio. Although the repository/archive functionality is central to the requirements of the Virtual Studio, rather than being the primary focus of the Studio, a ‘designerly’, dynamic user interface that encourages participation and collaboration is really key to the success of the Studio as a place for critical thinking and working. In effect, the actual repository should be invisible to the Architect who has little interest, patience or time for the publishing workflow that EPrints requires. More often that not, the Architects were talking about wiki-like functionality, that allowed people to rapidly generate new Studio spaces, invite collaboration, bring in multimedia objects such as plans, images and models, offer comment, discussion and critique. As student projects developed in the Virtual Studio, finished products could be archived and showcased inviting another round of comment, critique and possibly derivative works from a wider community outside the classroom Studio.

Our conference paper discussed the difficulties of ensuring that the (minority) interests of the Architecture staff were met while trying to gain widespread institutional support and sustainability for the Institutional Repository which the LIROLEM project aimed, and had an obligation, to achieve. During the presentation (below), we asked:

Can academics and students working in different disciplines be easily accommodated within the same archival space?

The paper argues that advances in technology result from complex and often conflicting social interests. Within the context of the LIROLEM Project, it was the wider interests of the Institution which took precedence, rather than the minority interests of the Architectural staff.  I’m not directing criticism towards decisions made during the project; after all, I made many of them so as to ensure the long-term sustainability of the repository, but yesterday we argued that

architecture is an atypical discipline; its emphasis is more visual than literary, more practice than research-based and its approach to teaching and learning is more fluid and varied than either the sciences or the humanities (Stevens, 1998). If we accept that it is social interests that underlie the development of technology rather than any inevitable or rational progress (Bijker, 1997), the question arises as to what extent an institutional repository can reconcile architectural interests with the interests of other disciplines. Architecture and the design disciplines are marginal actors in the debate surrounding digital archive development, this paper argues, and they bring problems to the table that are not easily resolved given available software and that lie outside the interests of most other actors in academia.

Prior to the conference, I was unsure of what to do next about the Virtual Studio. I felt that the repository was the wrong application for supporting a collaborative studio environment for architects. Central to this was the unappealing deposit and cataloguing workflow in the IR and the general aesthetic of the user interface which, despite some customisation, does not appeal to designers’ expectations of a visual tool for the deposit and discovery of architectural materials.

However, the MACE Project appears to have just come to our rescue with the development of tools that query OAI-PMH data mapped to their LOM profile, enriches the harvested metadata (by using external services such as Google Maps and collecting user generated tags, for example) and provides a social platform for searching participating repositories. I managed to ask several questions throughout the day to clarify how the anticipated architectural content in our repository could be exposed to MACE.  My main concern was our issue of having a general purpose Institutional Repository, but wanting to handle subject-specific (architecture) content in a unique way. I was told that the OAI-PMH has a ‘set‘ attribute which could be used to isolate the architectural content in the IR for harvesting by MACE. Another question related to the building of defined communities or groups within the larger MACE community (i.e. students on a specific course) and was told that this is a feature they intend to implement.

Because of the work of MACE, the development of a search interface and ‘studio’ community platform has largely been done for us (at least to the level of expectation we ever had for the project). Ironically, we came to the conference questioning the use of the IR as the repository for the Virtual Studio, but now believe that we may benefit from the interoperability of the IR, despite suffering some of its other less appealing attributes. One of the things that remains for us to do, is improve the deposit experience to ensure we collect content that can be exposed to the MACE platform.

For this, I hope we can develop a SWORD tool that simplifies the deposit process for staff and students, reducing the work flow process down to the two or three brief steps you find on Flickr or YouTube, repositories they are likely to be familar with and judge others against. User profile data could be collected from their LDAP login information and they would be asked to title, describe and tag their work. A default BY-NC-ND Creative Commons license would be chosen for them, which they could opt out of (but consequently also opt out of MACE harvesting, too).

Boris Müller, who works on the MACE project, spoke yesterday of the “joy of interacting with [software] interfaces.” This has clearly been a central concern of the MACE project as it has been for the Virtual Studio project, too. I’m looking forward to developing a simple but appealing interface that can bring at least a little joy to my architect colleagues and their students.

ALT-C 2008: A different approach.

Joss Winn / / Conferences, Open Source, Software, Web

Today, I took a different approach to the conference and relaxed. I usually take the approach of trying to attend as many sessions as possible and absorb and report back on as much as I can.  However, I’ve found that this approach quickly leaves me exhausted and somewhat removed from the rest of the conference as it allows little time for reflection.

So, my third day in Leeds was a much more enjoyable and stimulating one as I attended sessions, picking up on one or two things that were being presented and following threads and tangents that I found online and from talking with people.  One term that I’ve heard mentioned a few times is ‘lifestream’, that is, an aggregation of online activity into a timeline that can be shared with others. You can see my lifestream by going to this page. You’ll see that following a conversation I had at F-ALT08, I looked again at OpenID and setup my own personal website as an OpenID server, learning a great deal at the same time.

You can also see that I joined identi.ca, an open source microblogging site like Twitter, and found details on setting up Laconica, the software behind identi.ca, on my own server and potentially, the Learning Lab. My experience using Twitter at the conference has really demonstrated the value of microblogging within a defined community as a way of rapidly communicating one-to-many messages and engaging in large asynchronous conversations.

In the morning Digital Divide Slam session, we formed small groups and with two people I’d met previously at the fringe events, created a ‘performance’ that reflected on a form of digital divide. We chose ‘gender’, and produced this (prize winning) video which is now on YouTube.

During the second keynote, I drifted off and began to think about e-portfolios and aggregating our online social activity into a profile/portfolio that is controlled by the individual and is dynamically updated. I’d heard about the Attention Profiling Markup Language (APML), and spent time considering whether this could be used or adapted for aggregating a portfolio of work and experience. APML is primarily aimed at individuals’ relationship with advertisers and at a later F-ALT session was able to discuss the suitability of APML or an APML-like standard for aggregating a portfolio of work. Consequently, I’m developing an interest in this area and in other online relationships that can be made between people (see this link, too) and the data that we generate through purposeful and serendipitous online activity.

Having listened to quite a lot of discussion about web2.0 applications over the last few days, I’m even more pleased with the decision to use WordPress as a platform for blogging, web publishing and collaboration in the Learning Lab. With WordPress, we’re able to evaluate many of the latest social web technologies and standards through their plugin system.  This flexible plugin and theming system has led to the development of an entire social networking platform based on WordPress, called BuddyPress, and because it’s basically WordPress with some specific plugins and clever use of a theme, it can use any of the available WordPress plugins to connect to Facebook, Twitter, YouTube, Flickr and other popular web 2 services.  I’m looking forward to watching BuddyPress develop.

In the evening, we attended the conference dinner at Headingley Cricket Club. It was a great location, with good food and excellent service and while sitting next to one of my digital slam partners, he showed me JoikuSpot, an application that turns a mobile phone into a wifi router. There on our dinner table, he ran Joiku on a 3G Nokia phone and provided wifi access to his iPod Touch. What a great way to share high speed network access among friends, while meeting at a cafe or park to discuss work or study.

I was impressed. The Learning Landscape had extended to the cricket ground.

OpenSim, OpenID and Open Microblogging

Joss Winn / / Conferences, Open Source, Software, Web

My second day in Leeds for the ALT Conference 2008 and I’m really excited about three open source applications that I’d like us to evaluate when I return to Lincoln.

Yesterday’s OpenSim – A pre Second Life taster workshop demonstrated the potential of having our own OpenSim virtual environment, either as a way to orientate new users to Second Life or actually develop a Virtual World, confined to the university network.

Today’s Hood 2.0, it’s a Web 2 world out there, introduced Laconica to me. This is an open source microblogging service, that would allow us to effectively reproduce a Twitter-like service, but within the confines of the university. I think for us, this has an advantage over Twitter because of the privacy issues surrounding the use of public microblogging services. It does also have the ability to hook into Twitter (and soon, Facebook), if desired.

During the F-ALT08 Edublogger session this evening, I met David, who works on identity systems as Eduserv. We talked about OpenID and how it can easily be set up to serve as an identity provider for one person or an entire organisation.  I’ve taken his advice and now run an OpenID server on my personal website (it took less than 30 minutes to install and test). I’ve also been looking at OpenID plugins for WordPress and indeed the Learning Lab blogs could act as OpenID providers for anyone with a blog. I need to speak to ICT Services about the issues surrounding this on an institutional scale, but for me personally, I’m really impressed with how simple the process was to regain more control over my own identity online.

Finally, on a different note, the Keynote this morning was by Hans Rosling of Gapminder. He gave a very similar presentation to the one on TED, which I encourage you to watch for beautiful visualisations of statistical data relating to social, economic and environmental development.
