new lease of life - reactivation of blog

Friday, July 8th, 2011

It’s taken a while but I have decided to reactivate this blog. It’s been dormant too long and there are too many thoughts I have that shouldn’t sit in my mental silo but rather should be available for public discussion (though not all will be worthy of that).
In addition to writing new blog entries, I have realised that there are 17 drafts that have never been published due to being incomplete or “not quite perfect yet”. I think this is a major issue that is a huge failure in knowledge management particularly in the corporate world: We have such a drive for perfection and are so worried about bad feedback that quick and dirty ideas are never shared and even relatively finished spreadsheets, reports, research is not shared internally (or with the world).
So, think of it as getting rid of your junk out of the closet, storage, basement - because if you haven’t made use of it in a year or two chances are you won’t ever again (do save a few old photos and letters so your loved ones can have a laugh in the not so distant future)
Here’s to keeping my word…

Dopplr Raumzeitgeist 2007: Where we went last year

Friday, February 1st, 2008

So some people will probably have heard of Dopplr. It’s a online community based around travelling and encouraging meetings while travelling. And according to the MediaGuaridan it is one of several media sensations to watch in 2008“…

Today, they published a Raumzeitgeist (musing on Google’s Zeitgeist) which is a — rather basic — analysis of collected travel data. Most visually striking is of course their map of where the Dopplr community went:

Dopplr Raumzeitgeist 2007 - map of travels

Unfortunately we don’t know much about the data and in fact once you think about the map it’s also a bit lacking in information content:

  • what is mapped?
  • is it destinations or destinations and origins (probably the difference is not significant)
  • there’s no data about the all important numbers: e.g. how popular was a destination (could we vary the brightness of the plotted circles to show popularity?)

Also interesting is their graph of travel distance vs. frequency. I’d imagine that short journeys will not be recorded as much as long (expensive and/or significant) travels. So again the data is rather suspicious. But nevertheless, it is quite intriguing that there’s a dip in frequency for travels around 5-8000 miles (how dare they use imperial measurements!) - does that correlate with landing in the middle of a large ocean?
