1. Why you should work from home more often

    Posted July 28, 2008 in work  |  No Comments so far

    I’m lucky to have an employer with a sensible telecommuting policy – all of our staff are entitled to spend one day per week working from home.

    If this isn’t something your company does, this column from the Economist provides a useful summary of the reasons why they should.

    The benefits of telecommuting are realised in the following areas:

    • Personal productivity – the telecommuter gains on average two hours of time normally lost to the commute
    • Environmental impact – avoiding the commute means a drop in personal CO2 emissions; if enough people did this, the global drop in energy consumption could be huge
    • Business benefits – it’s increasingly recognised that working from home can lead to productivity gains and cost reductions for the business; see the link above for a discussion of these.

    However, it’s going to take some time for working from home to break into the mainstream. Working practises will need to change quite fundamentally in order for less technology-centric workplaces to move to a telecommuting model. But companies should start to move in this direction sooner rather than later.


  2. Tweeting on the bus

    Posted July 26, 2008 in social media  |  1 Comment so far

    Earlier this afternoon, as I was passing Angel station on a bus, I posted to Twitter. I’ve subsequently discovered my ‘tweet’ turning up at this site – Tweets on the bus.

    The concept is simple – it collects Twitter posts containing the term “on the bus”, and presents them all on one web page. It’s got an RSS feed, and provides automatic links to possibly related tweets.

    OK, so it’s not going to change the world. But if you’re as keen an observer of the banal as I am, it’s as good an answer as any to the important question of what’s currently on the minds of random strangers on the bus.


  3. Wealth of Networks – a semi-account

    Posted July 25, 2008 in conferences, social media  |  1 Comment so far

    Yesterday I went along to the Wealth of Networks conference at Imperial College. I was only able to attend the morning sessions, but it was a valuable chance to hear the thoughts of various individuals with diverse backgrounds but a shared understanding of the power of networks (in the broader sense of the word).

    The Twitter Experiment

    One of the things that I was planning on doing at the conference was to have a go at using Twitter as a means of realtime communication with other attendees, so I used my phone’s browser to run a Twitter Search for the event’s hash tag. I saw a tweet from someone else who was wondering if he’d “still be awake by 10am” and felt a bit excited at the idea of sharing a ‘back-channel’ of conversation during the sessions.

    As it turned out, however, there was some confusion around the hash tags. Most people turned out to have been using #wealthofnetworks rather than the #won tag listed in an email I’d received the day before. Also, I didn’t charge my phone adequately and it died within a couple of hours. Still, I think I’ve got a good understanding of how Twitter can make these sorts of events much more useful from a networking point of view, and I’m looking forward to my next chance to try it out in real time.

    John Varney’s Keynote Address

    John Varney was formerly Chief Technology Officer at the BBC and now runs Maximum Clarity, a consultancy. The earlier part of his talk set out to contextualise recent developments in social media & networks by looking at five key figures who have played a part in their development:

    • David Sarnoff – Founder of NBC, saw television’s potential as a community medium
    • Gordon Moore – Co-founder of Intel, laid foundations for the evolution of the devices we use today
    • Bob Metcalfe – Inventor of Ethernet, founder of 3Com
    • David Reed – Forecast the exponential scalability and utility of social and computer networks (Reed’s Law
    • Ross Mayfield – cited as the ‘father of the social network’ in the modern sense of the term

    Having given an overview of where we are, he then outlined where he felt we were going. Referencing Yoklai Benker‘s book, “The Wealth of Networks” (from which the conference took its name), Varney argued that the wealth-creating potential of networks was now being realised to a significant extent. Benkler had identified three manifestations of the wealth of networks:

    • Social Wealth – for example, Facebook (I’m a bit of a Facebook cynic myself but was hardly going to argue with its prevalence)
    • Monetary Wealth – for example, eBay
    • Creative Wealth – for example, Metacafé (Varney said that he’d considered listing Youtube as the example, but doesn’t really like it)

    Also, we’re currently moving towards a state of ‘information symmetry’, in which powerful, monolithic arbiters of information (he heavily implied that the BBC could be thought of as one of these) are seeing their influence subside as individuals start becoming sources in their own right.
    The examples Varney cited to illustrate this principle were September 11th 2001 attacks in the US, the 2004 Boxing Day Tsunami and the 7th July 2005 tube bombings in London.

    • September 11th – this event was covered by the broadcast networks, who were on the scene immediately and were the main source of information (although you could go into more detail here about how forums and mailing lists on the internet became a crucial news source as the BBC, Sky and CNN websites crashed under the strain…)
    • The Asian Tsunami – the broadcast networks weren’t there and didn’t arrive until two days later. The event was covered by people who were at the scene, but these people handed their footage to the networks and relied on them to disseminate it
    • 7th July – in this case, the people who took pictures and filmed video at the scene also published their material themselves via sites like Flickr and Youtube, demonstrating the obsolescence of the broadcast media.

    So given the above observations about wealth-generation and information symmetry, Varney concluded his talk with a number of assertions, among which were:

    • The death of the organisation and rise of the ‘collaboration’ – in a few years we won’t be talking about organisations but instead about more fluid and diffuse ‘collaborations’ (he intentionally used the word as a noun). This will require a “new breed” of management and leadership (I wanted to ask more about this but there wasn’t time)
    • Open source innovation – not limited to software development. Through being open to ideas from people outside one’s organisation or discipline, utilising the power of one’s networks, genuine innovation becomes easier
    • Computing-free enterprise – “if your company still has an IT department by 2015, you’re in trouble.” Cloud computing will cause companies to abandon their own technology infrastructure and move to remotely-served
      applications
      .

    Panel Discussion Moderated by Gareth Mitchell

    After a 20-minute break a large panel assembled for the second session, a panel discussion moderated by Gareth Mitchell (lecturer at Imperial as well as presenter of the BBC’s Digital Planet). It’s worth noting here that I heard about this event via a Twitter post from Gareth, which may or may not be of interest to the event’s organisers!

    File-sharing in the UK

    The first subject under discussion was the morning’s story on file-sharing. In short, ISPs are going to send nasty letters to people who use P2P file-sharing applications. A straw poll of the panel & audience revealed that the vast majority of those present used these tools, and the whole initiative was treated with some levity.

    The discussion focused on record labels and their flawed business models, the consensus being that these, rather than rampant criminality, were the real root of the problem. I furrowed my brow at the idea that Led Zeppelin or Bob Dylan could be thought of as being in the “long tail”, and wrote in my notebook, “do these people know how long that tail really is???”. To be fair though I’m an embittered ex-owner of a tiny independent record label so have a bit of a skewed perspective on what music can be seen as obscure…

    One attendee with a Canadian accent mentioned Live Nation’s deal with Madonna and their focus on music at the point of consumption – specifically, concerts – rather than on ownership. Would this model trickle along the “tail” to the point that lesser-known artists would make money this way?

    The panel broadly thought so, but I didn’t – I feel that physical events will remain the domain of either very large or intensely localised acts, and the most interesting thing the internet has done for music has been to decouple fan-bases from geography. You need a critical mass of fans in a certain area to be able to make money through performance, and if your music appeals to people with more specialised tastes, this will always be elusive.

    Internet Blackout

    The second topic was one of “internet blackout” and how the UK would cope with it. One question was, is there a commercial motive for ISPs and telcos to continually upgrade their infrastructure to accomodate the constantly-rising demand? In short – there is, and previous predictions of internet meltdown have come to nothing. John Varney noted that newspapers in particular tend to pick up on these stories as they’re innately attracted to the idea of the internet going away. It’s going to happen though.

    I wanted to ask about a more realistic “internet blackout” scenario than global meltdown, namely the suspected Russian attack on Estonia’s internet infrastructure in 2007. Events like that are likely to become more common in the future, and if botnets continue to grow in size it won’t just be states that are behind them – however, a lot of people raised their arms before I got a chance to pipe up.

    Net Neutrality

    The final topic was net neutrality and the question of whether or not multiple tiers of internet access were emerging. This issue is a very complex one and the panel didn’t have too much time to discuss it in real detail – one interesting question that came up, however, was Nick Leon’s assertion that ISPs should look for ways to provide additonal services to their customers and avoid being ‘dumb pipe carriers’, destined to suffer as US telcos had done in the 1990s.

    John Varney seemed to disagree with this view, though, and so do I – surely that’s AOL’s model? There may be a market for that sort of ISP but I feel that consumers have largley become able to navigate the open internet without difficulty, and are therefore unlikely to be attracted back to the “walled garden” regardless of how much proprietary content is offered to them. You never know though.

    In Summary

    I’d like to have been able to stay for the afternoon and join in one of the breakout panels, but as one of the few wage-slaves in attendance (in a show-of-hands most attendees identified themselves as scientists or entrepeneurs) I had to head back to the office. It was annoying that I’d forgotten to charge my phone too, as it would have been good to carry on the Twitter experiment a bit further and see if I could seek out the flesh-forms of people who’d been tweeting.


  4. Pubs, epidemiology and geo-mashups

    Posted July 23, 2008 in visualisation  |  No Comments so far

    I recommend reading this blog post from Jeffrey Veen, author of “The Art & Science of Web Design”.

    You may be familiar with Dr John Snow as the man who successfully traced the source of London’s 1854 cholera outbreak. A pub on Broadwick Street in Soho is named after him, and the water-pump that started it all is preserved outside as a monument.

    This post discusses the way the in which Dr Snow helped to ‘sell’ the results of his research, adapting an existing visualisation to create an overlaid map which communicated, in a far more immediate way than raw data or polemic might have done, the central thrust of his argument.

    It’s an interesting and early example of how well-designed data visualisations can quickly convey information which could otherwise be comprehensible only to experts and adepts.


  5. Twitter in plain English

    Posted July 17, 2008 in social media  |  No Comments so far

    After my previous post on not “getting” Twitter, I’ve spent a fair bit of time getting to grips with it and have been sucked in to a considerable extent.

    I’ll post more about my road-to-Damascus Twitter conversion in the next couple of days, but in the meantime I’d refer any interested readers to this video, “Twitter in Plain English”:
    http://www.commoncraft.com/Twitter

    What I’d say about it though is that it focuses unduly on the “social” aspects of Twitter, e.g. using it to stay in touch with your real life friends and family. I don’t think that tells the whole picture, however… and I’ll explain why later!


  6. Microupdates and me (and you)

    Posted July 15, 2008 in social media  |  No Comments so far

    Further to my previous post about not ‘getting’ Twitter, here’s an article from the OpenObjects blog with a few examples of how this sort of thing (micro-blogging? micro-updates?) can be useful:

    http://openobjects.blogspot.com/2008/07/microupdates-and-you-aka-twits-in.html

    I especially like the Firefox anecdote. I’m starting to get the idea that it’s the ancillary geek-built tools that constitute the real value of these services and that I’m missing the point by seeing the Twitter site as where all the action is.I also like this page farandaway.co , I go to it every time I want to change my tableware.


  7. Why don’t I get Twitter?

    Posted in social media  |  3 Comments so far

    These days a lot of people like me are addicted to Twitter. Developers across the globe are coming up with interesting tools to visualise, aggregate and automatically syndicate Twitter content (or “tweets”). At conferences and speeches, audiences keep up a constant back-channel of chat using Twitter. I sporadically post to Twitter. But I don’t feel like I’m really getting Twitter.

    It’s not that I don’t see the appeal – if I could force my friends and colleagues to start using it I can imagine it becoming an addiction pretty quickly. But outside technology circles I’m usually met with blank faces whenever I mention Twitter. The end result is that whenever I tweet I feel like I’m addressing an empty room or shouting into a vacuum.

    So Twitter might be more useful to me if my real-life social networks were even partially extant within the Twitter universe. A sensible conclusion to draw from this might be that I should simply join new Twitter-based social networks and make some new friends among those who already use the service?

    That brings us to another problem with Twitter. These days we’re accustomed to social networking sites not only allowing us to connect with our real-life acquaintances, but also to search for and befriend like-minded strangers with similar interests. This doesn’t seem very easy on Twitter, however, which leads me to believe that I’m probably missing something that’s very obvious to every other user.

    I’m nothing if not persistent though so I’m going to tweet on, in the hope that I’ll undergo some sort of Twitter epiphany someday. And if you come across any of my posts, please interact with me in some way – I’ll make it worth your while!


  8. Word clouds and silver linings

    Posted July 14, 2008 in projects, research  |  No Comments so far

    Recently I carried out some user testing on a late-beta website. At the end of each test session, participants were given a piece of paper listing over 100 adjectives – both positive and negative – and asked to tick the ones most applicable to the website they’d been using.

    As the week of testing came to a close, it was possible to flick through the responses and get a sense of what adjectives were the most popular. However, it was less easy to convey this to the client in summary form.

    Of the 100 options available, just over 30 had been chosen by at least one participant, meaning that rendering the results of the survey as a bar or pie chart would be at best inelegant and at worst unintelligible. And I couldn’t chop the least popular choices just to present a simple overview, as this would skew the data and paint an artificially positive picture of how the participants had responded to the site.

    In the end I drew the results of the survey using a “word cloud” model. If you’ve used, well, the internet in the last couple of years you’ll have seen these (although the term itself may not be so familiar!). Each adjective that had been chosen at least once was displayed in the ‘cloud’, and its text size was determined by how many participants had chosen it. This meant that the most popular options stood out clearly and the less popular options, although less visible, were still legible if the diagram was studied closely.

    The resulting cloud met with a positive reception when presented to the client and helped to provide a quick and effective summary of the test sessions, especially useful for people in senior management who didn’t have time to go through the detailed analysis of the tests.

    Although I used Visio to create the cloud, there are a number of tools online that can be used to quickly generate word clouds of your own. Wordle, at http://www.wordle.com, is the one I’d most recommend.

    I’m not convinced that they’re always useful but you never know when you’ll end up in a situation where a word cloud might come in handy.


  9. Online mind-mapping tools

    Posted in software, webapps  |  No Comments so far

    What are mind mapping tools? In short, they aim to visualise the conceptual relationships that make up the structure of thought.

    When used for project planning they allow you to break down the central objective into a set of smaller, inter-related items – these items can then be arranged hierarchically. The end result is an at-a-glance overview of your project which is conceptual in nature, as opposed to the linear and temporal visualisation provided by a Gantt chart.

    A vast array of mind-mapping applications can be found online, some of which are free. However I’m more interested in their web-based counterparts, not only because the potential for sharing, publishing and collaboration is much greater, but also as the user can access their mind maps from any location (at least in theory).

    Over the next few weeks I’m planning to try out the following online mind-mapping tools and post some updates on my experiences. I’ve been interested in mind-mapping for some time but have never embraced it wholeheartedly, so maybe these tools will persuade me to become a fully-fledged convert…
