I went swimming with Tess and Anna tonight and given that I’m not too well I only swam for 30 lengths, which left plenty of time to sit by the pool, watching the girls and reading New Scientist. Of the articles I read I was most amazed by this description of how honey bee swarms find a new site.
Several hundred scout bees set off to search potential sites, such as holes in trees. Each scout will spend about 30 minutes assessing relevant factors such as the size of the cavity, the presence of ants and the aspect of the sun.
The scouts then fly back to the cluster and use a combination of waggle dances and runs across the body of the cluster to transmit information about the site to the other bees. The more runs across the cluster a scout makes - on average 150 - the higher the scout rates the site.
The scout then revisits the potential home, taking one or two “recruits” with it to make their own assessment. If a recruit likes the site too, it will return to the cluster and give positive feedback in the form of a similar waggle-and-run combination, which generates yet more recruits, and so on. If enough recruits agree on a particular site, a “quorum threshold” is reached and the swarm lifts off to the new location. This ongoing recruitment process means that the swarm can simultaneously assess, compare and “remember” different sites during selection.
However, if recruits disagree with a scout’s positive assessment of a potential site, then support for it will fade away
A great example of how the sum of the parts is greater than the whole!

- Working on use cases for VDI #
- Off out for a walk with Debbie #
- Having breakfast with Debbie and watching the kite surfing. Unfortunately having to respond to a few emails as well. #
- Debbie’s gone off shopping so I’m spending a few mins reading Wikinomics on my Blackberry before getting back to the grindstone. #
- Finished wikinomics - a very good book and a perfect quick read on the Blackberry in summary form. #

- Just got soaked on the 3 minute walk to the kids school #
- Waiting at the doctors for my monthly barage of blood tests #
- Blood tests were painless. No chance of walking today in this rain. So off for a nice warm swim and a read of New Scientist by the pool. #
- Just finished swim. No feed reading today I’m off to Boaters Landing - just over the road from the pool - do do some programme design work #
- I’m lucky - the rain’s stopped and the sea’s in and there are plenty of people to chat to at the cafe #
- Planning finished, still a bit of work to do on durations. Decided to stay longer and enjoy the blue sky and get my Project Appraisals done #
- Decided to give my desktop a treat, after 27 days up time I’ve rebooted it and now instead of 110K system handles open, it’s only got 28K #
- Briefing Q on the programme design and tasks #
- Off to the hospital for a meeting with my specialist #
- My specialist is concerned that my trends graphs showing me getting worse, so he wants me back on night time pain killers and more tests #
- Now at the swimming pool again, but this time with the kids for their lessons #

- Walking to Blackpool - half way - relaxing in the excellent Solaris Centre cafe and reading about the plans for a new Blackpool library #
- Listening to a facinating podcast while walking by the author of "cradle to cradle" - business should seek to do "good" not just less harm! #
- Family are scattered all over today, so I’m on my own, but the walk on the beach to Blackpool was excellent and the poptech podcasts r great #
- Big benefit of 12 miles of walking is that I’m in less pain and get to eat a sausage jumbo and cherry scone and now onwards to the cinema #
- Blackpool’s ok in small doses, but I’m pleased to be in the relative peace of the cinema. Waiting for Charlie Wilsons War to start. #
- Now I’m resting I have so many thoughts running through my head. Bit annoyed at having the virtual desktop stuff dropped on me so late #
- Excellent film. Funny, emotional, and very worrying - that a world problem was adressed like a popularity contest #
