Our 24-hour hack: OpenFreecycle

URL: dharmafly.com/openfreecycle

Streuth. Hot on the heels of last week’s UnLtdWorld award, I was amazed to experience the web application that I created with Tom Leitch being awarded the top two prizes Yahoo’s OpenHackLondon. And this, after winning a prize with ‘HackHUD‘ at the previous Hack Day London, two years earlier (the famous one, when it rained inside Alexandra Palace).

OpenHackLondon is an opportunity for web developers and programmers to get together, to collaborate and experiment with new ideas in technology. The focus is a 24-hour (overnight) hacking challenge, with a two-minute demo by each team, and prizes in several categories.

OpenFreecycle

Our entry was OpenFreecycle – an itch that I’d been wanting to scratch for a couple of years. This was an attempt to make community sharing of free, unwanted items much more easy and accessible. Sort of like eBay, but for free.

Our two-minute presentation to the crowd

There are around 10,000 local “Freecycle” mailing lists (all of them are hosted on Yahoo Groups). They offer an extremely useful service: a way for people to offer or find unwanted items amongst their local community. Got a spare mattress? Put it on Freecycle. Need a chest of drawers? Find one on Freecycle.

The Problem: Closed

The system, however, is far from ideal. Each group is initially private and closed. You need to request membership and await approval for each group before you can see what’s available. Prospective browsing in neighbouring groups becomes a painful task.

Over 10,000 Freecycle mailing lists on Yahoo Groups

And then there are the emails – hundreds in your inbox every day. And, because each group is just a plain and simple, private email list, there is no way to expose all that interesting content to other places on the web. That is, until now…

The Solution: Open

A simple, searchable, open system, with the option to subscribe to feeds for specific search terms in specific area (e.g. ‘baby’ in Leeds), the possibility to subscribe to alert notifications for specific items and the ability to integrate all this content around the web, for example with Greasemonkey in shopping sites, to inform you when an item is available for free in your local area:

What we built was a rough proof-of-concept. It only handles the Leeds group – and very simplistically, at that – but it gives an idea of what is possible when you start to open up data.

(Of course, there are merits in selected aspects of the system being closed, or guarded – e.g. in protecting user’s contact details, and the ability to identify potential exploiters, such as tradesmen scooping up everyone’s free offerings. These need to be preserved, for the health of the community.)

How we did it

Here are the slides from our demo:

We used the Yahoo Mail API (via PHP) to log into a subscribing mailbox, then converted the emails to Atom feeds (with Perl), imported these into Yahoo Pipes and performed geo-location, term-extraction and some other bits and bobs, drilled down into the resultant feeds with YQL and then presented the lot using the Google Static Maps API and a smattering of jQuery. Voilà!

We Won the Double!

Moment of glee

OpenFreecycle won both the “Hackers’ Choice” prize, as voted by the 300 participants, as well as the “Best In Show” prize, unanimously awarded by the competition judges:

• David Filo, co-founder of Yahoo
• Tim O’Donoghue, vice-president of engineering at Yahoo
• Sophie Major, head of international at the Yahoo Developer Network
• Pascal Finette, Mozilla Europe
• Matt Biddulph, co-founder of Dopplr
• Daniel Ek, co-founder of Spotify

Check out the other winners and all the Hack Day entries – there are some ingenius little gems to be seen.

Whatever Next?

Take OpenFreecycle for a spin. Have you got any ideas? How would you improve the experience of local sharing?

The BRIC award - photo by Jane Middlehurst

At last week’s beautiful UnLtdWorld first birthday gathering, I was honoured to collect a shiny BRIC award, for “using technology for social good in the most creative and innovative way”.

Thank you to everyone who voted for Dharmafly, and to all who have supported us in the last 2 years.

There were five award categories, with an array of nominees, each of them involved in the finest of projects. Although UnLtdWorld is an online social network (it brings together those with an interest in positive social change), it was a particularly rich experience to meet in person so many passionate and focussed individuals. And there is a growing number of meetups in this area, such as Social Innovation Camp, the Shine Unconference and 2gether.

Felix Gonzales produced this video:
(please excuse my slightly gushy, tongue-tied jabbering – I must have been having a rush)…

And here it is on my desk, as promised:

Update: And another very special, double award was received over the weekend. More on that later today very soon right here…

Dharmafly are chuffed to have been nominated for a BRIC award with UnLtdWorld, the social network for social entrepreneurs. You can vote with your feet (erm, your mouse) right here.

Since its launch, one year ago, UnLtdWorld has gone from strength to strength as a platform for collaboration, helping people to work together for social change. We’re listed in the Digital Award category, for those “using technology for social good in the most creative and innovative way”:

The BRIC Awards aim to recognise the most active, inspiring and original members of UnLtdWorld, as voted for by its community.

They encapsulate what UnLtdWorld stands for: Business, Resources, Insight and Community – and members selected as nominees reflect a well-rounded approach to those elements.

Voting ends Friday 24th April, 5pm (UK time), and the winners will be announced at UnLtdWorld’s first birthday celebration, on May 5th.

The Bangladesh River Journey, a BBC World Service project to track climate change, for which we built the interactive mini-site, has recently received two prestigious awards. These awards recognise the innovative way that the project brought social media reporting on important global issues into an engaging user-experience.

Webby Honoree

The Webby Awards are like the Oscars for the Web. From nearly 10,000 entries, the Bangladesh River Journey was declared a Webby Honoree, “in recognition of outstanding work”.

Sony Radio Academy Awards

At the Sony Radio Academy Awards (“the Oscars for Radio”), the Bangladesh Boat Project won the Multiplatform Radio Award. That’s a photo of the award at the top of this post.

The awards body said:

This is a project that from the very outset was designed to make the most of the multiplatform landscape. It embraced everything from podcasts to GPS and Googlemaps to add value to the listener/user experience and met those listeners where they really lived using third party sites such as Flickr.

This is [...] about creativity and using the plethora of multimedia options now available to generate something unique and uniquely valuable. This is absolutely the paradigm for an interactive radio project in the current landscape and is by far the deserved winner.

These awards are testament to the bold, creative approach of the World Service and the well-knit collaboration within their team. It was a really exciting project to be involved with.

Well, this one didn’t get blogged yet… Back in June, we stayed up all night at the BBC / Yahoo Hack Day in London. The task was to combine data sources and build something experimental – and a little bit edgy.

We forged a script to enhance mainstream news sites (such as BBC News) with a layer of grassroots community content – from bloggers, photographers, and the like. The idea was to propagate the news and views from the streets, alongside mainstream media. The result: ‘HackHUD‘.

It’s a Greasemonkey userscript and it uses a number of Yahooey things (Pipes, YUI and Term Extraction), to display content from Flickr, Technorati and Newsvine.

We were clackety-clack on the keyboard, non-stop for over 24 hours. There were tears and laughter… and in the end, a prize.
