There’s a bit of me in PHP!

Last October I found a bug in PHP’s SOAP module. It was pretty obscure bug in the way PHP used Digest authentication. As it was a showstopper for me, I submitted a bug report and wrote a patch to fix it.

It took a while, but my patch has finally been merged into the 5.* and 6.0 sources!

I’ve been using PHP for ten years, and so it’s perhaps a little surprising it’s taken me this long to give anything back. Truth is, this was the first time I’ve come across a bug which halted my development work.

It’s a tiny fix, 6 lines of code, but it makes me happy that after all this time, finally, there’s a bit of me in PHP! Hurrah for open source software!

Geograph Torrents

Something Geograph has needed for some time is a way to get at the entire archive without causing us huge bandwidth bills – it’s currently around 100GB in size.

So I’m please to announce where you will be able to download the entire archive via BitTorrent!

More details…

We’re going to release the archive as a series of volumes, each containing around 50,000 images and weighing in at around 5GB. The first volume is available now, with a smaller sample volume which allows you to preview how the metadata is delivered.

All the metadata for each volume is delivered as a RDF formatted file called manifest.rdf, which should be self explanatory, here is a sample fragment:

<rdf:Description rdf:about=”00/00/000014.jpg“>
<dc:title>Durdle Door from the east</dc:title>
<dc:creator>Helena Downton</dc:creator>
<georss:point relationshiptag=”is-picture-of”>50.6205085825182 -2.27398572077417</georss:point>
<georss:point relationshiptag=”was-taken-from”>50.6211552007986 -2.26663784055893</georss:point>

How to download

If you are new to using bittorrent, you will need some software, such as Vuze (aka Azureus) or uTorrent. Once installed, go to and click a torrent link to set it downloading – easy!

Please seed!

Please seed these torrents if you are able – simply leave your torrent client software running after your download has completed. You’ll be helping others to complete their downloads faster!

OS Map Integration into Geograph Begins!

Ordnance Survey have sent the Geograph team 21 CDs of 1:50K maps. Huge thanks to the OS for making this possible, this data is otherwise prohibitively expensive to consider using within a site like Geograph.

Over the next fews days these are getting trickled up to the Geograph servers, and then Barry Hunter will perform the integration work. You can probably expect to start seeing some basic integration of maps into photo viewing pages before Christmas. This will really enhance the educational value of the site, something we’ll be building further upon in the new year.

Coincidentally, Ed Parsons offers a tantalising glimpse of OS Openspace today. Can’t wait to see that reach a public release…
