Selected (belated, extended) Saturday Links

The past two weeks haven’t really left time to compile my selected links, though there have been many. A few days at SxSWi (on which more, later) followed by travelling with the family and the inevitable work backlog moved blogging way down the priority list. So here’s a mammoth selection to get me caught up. Particularly interesting has been the discussion around the future of newspapers (represented here by Clay Shirky, Steven Johnson and Russell Davies), which seem to have finally pushed beyond “how t ind a good business model for papers” to looking at where the real value for society lies and how we can preserve and extend that in a changing landscape.

  • Making a jQuery Plugin Truly Customizable » Learning jQuery – Tips, Techniques, Tutorials

    Some nice tips for managing options, and a reminder to find _useful_ customisations not just load with customisation options without much thought about/consultation with other potential users

  • iPhone Coding For Web Developers

    Presentation slides from the internet's Matt Biddulph

  • Rack::Test released: Simply test any Rack-compatible app — Bryan Helmkamp

    There's a _lot_ to like about increased adoption of rack. "With Rack::Test, we hope to make it easy for frameworks to encourage their users to write tests by making it trivial to provide a testing environment. We’d like to foster compatibility between Ruby web app testing environments (especially important as ideas like multi-framework apps become more prominent). The philosophy is the library should stay small and extendable so frameworks can layer on additional functionality they want to offer without modifying Rack::Test’s core behavior or resorting to monkeypatching."

  • Newspapers and Thinking the Unthinkable « Clay Shirky

    "That is what real revolutions are like. The old stuff gets broken faster than the new stuff is put in its place. The importance of any given experiment isn’t apparent at the moment it appears; big changes stall, small changes spread. Even the revolutionaries can’t predict what will happen …. Ancient social bargains, once disrupted, can neither be mended nor quickly replaced, since any such bargain takes decades to solidify." … and a a lot more

  • russell davies: newspapers and all that

    "If we are going to create a new news ecosystem involving advertisers (and a lot of people would be grateful for that money) then we're going to have to do something about that institutional bifurcation between content and commerce. We're going to have to design the relationship between the two with the care of a good experience designer." – a response to Ben Hammersley asking if anyone talking about the future of newspapers had talked to anyone in advertising

  • Streams, affordances, Facebook, and rounding errors – Laughing Meme

    "Simon Willison asked this week about best practice for architecting activity streams. And the answer is, “It depends.” Depends on the scope, scale, access patterns, and affordances you’re building — your contract with your users.

    Which is a long way of saying think hard about the promises you make to your users, implicitly or explicitly.

    And, Facebook, my friend, what the HELL are you thinking? You managed to negotiate the best deal in the business, talk about a racket, and you threw it away for a piece of Twitter’s pain? Are you stupid? Well, best of luck with that."

  • SXSW Interactive Videos and Podcasts | SXSW.com

    Most of the sessions were recorded and this is the place to get hold of them.

  • SXSWi: Location-based service is the trend at Austin, Texas |

    "Predictably, location-based services were a major feature this year, with launches that included Foursquare, a social, location-based game by the Dodgeball creator, Dennis Crowley, and a new Facebook application for the location management tool Fire Eagle. While early adopters such as the SXSWers have been exploring location-based services for some time, it is inevitable that more consumer and privacy-friendly versions will start to creep into the mainstream."

  • stevenberlinjohnson.com: Old Growth Media And The Future Of News

    "I think it’s much more instructive to anticipate the future of investigative journalism by looking at the past of technology journalism. When ecologists go into the field to research natural ecosystems, they seek out the old-growth forests, the places where nature has had the longest amount of time to evolve and diversify and interconnect. They don’t study the Brazilian rain forest by looking at a field that was clear cut two years ago." … and …" Measured by pure audience interest, newspapers have never been more relevant. If they embrace this role as an authoritative guide to the entire ecosystem of news, if they stop paying for content that the web is already generating on its own, I suspect in the long run they will be as sustainable and as vital as they have ever been. The implied motto of every paper in the country should be: all the news that’s fit to link."

  • On running a panel

    A mixup over bus times meant I didn't make it to Andrew's panel at SxSW, but I heard many good things. It's really great to see this kind of debriefing-in-public going on. Hopefully it'll make for a stronger set of talks and panels next year.

  • Guardian API Maps – Home

    "This is a site that lets you search the Guardian's new API and add location information to articles. All the place data we collect is being made available to anyone who wants it."

  • Foursquare, Hot New Phone App, Is Dodgeball on Steroids | The New York Observer

    Quite a few people seemed to be playing with Foursquare at SxSW but most of the Brits were excluded as we didn't want to use that much data and it wasn't available in the UK iTunes store. One to watch, though.

  • A few notes on the Guardian Open Platform

    I saw Simon present the Guardian Platform at SxSW and it looks like a great achievement. Waiting to see what developers build on it, and how they roll some of the ideas back in

  • Taking remote imagery offline to Nigeria :: High Earth Orbit

    Andrew's notes on trying to source good map data for use in Nigeria. It's a useful overview of a variety of services and ways to use them, though highlighting the absence of really accessible, high-quality data.

  • Pulse Laser: The Utility of the Unfinished

    "One technique that S&W has been using recently to illustrate design work is placing sketches or wireframes in situ. Whilst wireframes themselves are incomplete artefacts, designed to be work in progress, they still suffer for being uniformly incomplete. Wireframes themselves can be almost too beautiful, and this means that it becomes all-too-easy to criticise them as only wireframes, rather than as part of a product that exists in the world. Contextualising the sketches into the photograph places the design into the world. This enables the design to be understood within the world, and also (importantly) to highlight the seams between the unfinished design and the finished world around it"

  • Spike: a log file viewing & (if we’re being generous) analysis tool for Rails developers.

    Looks like a handy addition to the toolkit

  • Generation Open | FactoryCity

    "Sharing and giving away all that you can are the best defenses against fear, obsolescence, growing old, and, even, wrinkles. It isn’t always easy, but it’s how we outlive the shackles of biology and transcend the physicality of gravity." – Perhaps an overly optimistic piece, but it connects together a number of current themes and we can hope…

  • Testing Facebook with Cucumber | opensoul.org

    For those faced with the unpleasant task of writing facebook apps, some people are working on making sure they can be thoroughly tested.

  • scraplab : instant sinatra deployment with heroku

    A lot of people seem to be excited about heroku lately, and it does look like a nice simple way to put up quick ruby apps. Must play soon.

  • How to speed up gem installs 10x « The Budding Rubyist

    Handy little tip, particularly for server environments: turn off ri and rdoc generation in your .gemrc file, and speed things up considerably

  • Facebook in 2010: no longer a walled garden – O'Reilly Radar

    A more positive spin on facebook's changes from David O'Recordon, who suspects they're going to pull down the walls around their garden and become a proper citizen of the open web.

  • Facebook blinks, copies Twitter, still gets it wrong. – broadstuff

    Critical commentary on facebook's recent changes. I'm not sure I entirely agree with statements like "By 2009 it was clear no one gives a sh*t about the Social Graph" but facebook really do seem to be finding that their approach is overly complex and quickly trying to shift to a more twitter-like "web of flow" (to steal Stowe Boyd's phrase)

  • Acquia Search goes public beta | Acquia

    Hosted solr for drupal: "Acquia Search can be installed as a module on any Drupal 6 site, and enhances a site's search experience with faceted search navigation, content recommendations, and configurable results weighting, all delivered through a redundant hosted service infrastructure.".

  • Oauth using pecl/OAuth

    Looks like a nice simple way to interact with oauth from a PHP app

Rails 2.0 : Very Soon Now!

All reports, and the evidence of the subversion commit log, says Ruby on Rails 2.0 will be with us very shortly. Apparently the announcement has been delayed until the gems have properly circulated. For those who’ve not been following, Rails 2.0 isn’t going to seem like a huge step forward as it’s mainly focussed on cleaning up existing features, and moving quite a few out of the core and into plugins.

I’ve converted quite a few projects over to be 2.0-compatible over the past few weeks and I’ve always come away feeling like my projects are cleaner as a result. It’ll be interesting to see what the benchmarks say about the performance impact of the new release.

Some of my favourite features of the new release are:

New view filenames and improved mime type support

Rather than filling up your views folders with .rhtml, .rxml, and .rjs files you’ll now be looking at filenames of the form myaction.html.erb, myaction.atom.builder, etc. If you ever found yourself working with the likes of myaction_atom.rxml, myaction_rss2.rxml, and so on, you’ll understand that the new naming system makes life simpler and your code simpler. In general, it really feels like the support for different formats that has been creeping into rails for a while now is finally coming of age with 2.0.

Pseudo-mime types

Closely related to the previous point, it’s nice to see an officially supported way to present different content to different devices just as you’d supply different formats for different requests. That’s written up well in this piece on building an iPhone UI for your Rails 2.0 application, and would have come in very handy when I was doing my work on intercepting microformats in rails input. Put simply you can define extra aliases for a given mime type, eg:

Mime::Type.register_alias "text/html", :my_extra_format

then use a before filter to identify a request as your pseudo-mime type:

  before_filter :detect_input_format

  def detect_input_format
    if request_matches_my_criteria?
      params[:format] = "my_extra_format"
    end
  end

and then the resulting action will render the view myaction.my_extra_format.erb (or myaction.my_extra_format.builder, etc.).

If the long-predicted explosion of the mobile web does indeed come in 2008, or more people adopt the facebook application approach, I can see this feature getting a lot of attention.

ActiveRecord Query Caching and Serializations

Lots of databases support native query caching, but it’s good to see it going in at the ActiveRecord level as it’ll sit a little closer to your app and be something you can rely on. I’ve seen a good speed up on some apps that I’ve been running on Edge.

ActiveRecord objects can now be created from XML and serialized to json much more easily, making inter-operability still easier.

And a lot more

The new initialization process is great, being able to specify :moved_permanently in redirects has cut out code I never liked, fixtures make a lot more sense, the view cleanups are great, and there’s a lot of stuff I never used which is no longer taking up memory in my processes. My experiences with Edge Rails lately mean I’m very pleased with Rails 2.0, am glad that this release is so focussed on clean-up, but I’m also looking forward to seeing what radical changes and refactoring come along once this version is out the door.

You can learn more about Rails 2.0 by checking out this post on the Riding Rails blog, the videos at railscasts.com and Ryan Daigle’s posts on Edge Rails. I’m sure a lot more will emerge over the next few weeks.

UPDATE (later that day): DHH has announced it and it’s official: Rails 2.0 is now out.
