Hey why does the total keep changing?!
So we’re well on our way now to our target of 1 million clicks in 100 hours. Not that we want to get complacent though – keep classifying everyone!
Being part of Galaxy Zoo gives me the opportunity to combine web technologies with science, a perfect mix! When we came up with the idea of the Zoonometer™ we decided that if possible we’d like the total to update in near-relatime. We launched the Zoonometer™ with it auto-updating every 10 seconds but quickly realised with the sheer number of people coming to Galaxy Zoo, this continual refreshing was causing the database to get pretty slow. So onto version 1.1 of the Zoonometer™. We’re now caching the count and recalcualting the total every minute and I’m pleased to say we’ve significantly lowered the load on the servers.
One side effect of this caching however is that if you refresh the browser you might hit one of the other webservers which has its own internal cached value. There’s nothing funny going on I promise but you sometimes might see the Zoonometer™ jump around a little.
