We show live footprint estimates for right now on our dashboard at http://www.mastodonc.com/dashboard, but it’s also pretty interesting to visualise the different locations over time to get a feel for the size of fluctuation to see how the horse race between time zones and temperatures plays out.
Yet another GigaOm article with a linkbait headline but genuinely interesting content, which is well worth a read - “The controversial world of clean power and data centers”.
GigaOm published this interesting and provocative article last week, headlined ‘Why the days are numbered for Hadoop as we know it’.
An interesting thought on waterfall, agile and long term vision came up on the London Java Community mailing list.
HP have done a pretty cool proof of concept for a ‘net zero’ data centre which shifts workloads to match the availability of power from solar panels - which means that most of the power ends up being green, rather than coming from a less-green national grid.
Looks like Infinity DC are building a biomass-powered data centre near London.
I showed in my post last week that the biggest determinant of good vs bad carbon footprint for a data centre is what power source it runs off.
I’ve heard some very confident but completely conflicting claims lately about what is ‘the important thing’ in the carbon footprint of compute jobs. The dissonance was starting to get to me, so I’ve done some back-of-envelope calculations of different scenarios to figure out what the order of importance of the factors actually is. I soft-pedalled the impact of power source as much as possible, since a priori I thought that was the most important one and I didn’t want to be biased.
Well, this has been an exciting week.
