Big data: Welcome to the petacentre : Nature News

2008 Sep 9, 8:29Article on the data centers that backup the Internet Archive and handle CERN's LHC's data. "CERN embodies borderlessness. The Swiss-French border is a drainage ditch running to one side of the cafeteria; it was shifted a few metres to allow that excellent establishment to trade the finicky French health codes for the more laissez-fair Swiss jurisdiction. And in the data sphere it is utterly global."PermalinkCommentslhc history internet cory-doctorow nature physics network hardware library science cern internet-archive

Neil Fraser: News: Wooden Brain

2008 Sep 8, 6:51Neil prints out brain cross sections from an MRI and pastes them onto a set of wooden cubes forming a model of his brain. "Last month I took a left-right MRI scan, reconstructed it, and rerendered top-bottom and front-back scans... Another method to visualize a complex 3D object is to build a model. The dimensions of the MRI data cuboid are almost exactly 3x4x5. Accordingly, I obtained 60 one-inch cubes ... arranged them appropriately, varnished the 94 outside faces, printed nine carefully selected cross-sections and their mirror images, sliced the prints into 266 squares and glued them to the correct internal faces."PermalinkCommentsart design brain toy model wood

Tag Metadata in Feeds

2008 Aug 25, 10:13

As noted previously, my page consists of the aggregation of my various feeds and in working on that code recently it was again brought to my attention that everyone has different ways of representing tag metadata in feeds. I made up a list of how my various feed sources represent tags and list that data here so that it might help others in the future.

Tag markup from various sources
Source Feed Type Tag Markup Scheme One Tag Per Element Tag Scheme URI Human / Machine Names Example Markup
LiveJournal Atom atom:category yes no no , (source)

Facebook Profile Views Application - Failed Idea

2008 Aug 21, 11:24

I had an idea for a Facebook app the other day. I wondered who actually looked at my profile and thought I could create a Facebook app that would record this information and display it. When I talked to Vishu though he said that this wasn't something that Facebook would be too happy with. Indeed the Platform Policy explicitly disallows this in section 2.8. This explained why the app didn't already exist. Its probably for the best since everyone assumes they can anonymously view Facebook profiles and would be irritated if that weren't the case.

On the topic of assumed anonymity, check out this article on the aggregation and selling off of your cell phone data including your physical location.

Leaking Information Through Delicious

2008 May 18, 6:45

While re-reading Cryptonomicon I thought about what kind of information I'm leaking by posting links on Delicious. At work I don't post any Intranet websites for fear of revealing anything but I wondered if not posting would reveal anything. For instance, if I'm particularly busy at work might I post less indicating something about the state of the things I work on? I got an archive of my Delicious posts via the Delicious API and then ran it through a tool I made to create a couple of tables which I've graphed on Many Eyes

I've graphed my posts per week and with red lines I've marked IE7 and IE8 releases as stated by Wikipedia. As you can see, there doesn't seem to be much of a pattern so I suppose my concerns we're unfounded. I use it for both work and non-work purposes and my use of Delicious isn't that consistent so I don't think it would be easy to find a pattern like I was thinking about. Perhaps if many people from my project used Delicious and that data could be compared together it might be easier.
For fun I looked at my posts per day of week which starts off strong on Mondays and decreases as the week goes on, and my posts per hour of day. It looks like I mostly post around lunch and on the extremes I've only posted very late at night twice at 4am: converting media for the Zune, and Penn's archive of articles. In the morning at 7am I've posted only once: document introducing SGML.PermalinkCommentsmanyeyes graph cryptonomicon delicious

Juanita Beach Visit and Map

2008 Mar 7, 3:26

Don't Feed the Ducks SignTwo weekends ago it was actually sunny and kind of warm so Sarah and I went down to Spud Fish and Chips and Juanita Beach Park. We ate fish and chips on the dock. I took a few pictures and this time actually put some geographical information on Flickr so now I've got a map of my tiny fish and chips journey. On the map click on the floating marks to view the associated photos.

Flickr provides access to the geo data associated with your photos via GeoRSS feeds. And Google Maps displays GeoRSS feed content on their maps allowing you even to edit the data but doesn't appear to let you easily export the GeoRSS. Live Maps does the inverse, allowing you to create and export GeoRSS data but not import it. I'd like both please. Oh well.
