Devtools startups – standing out to investors
Published in Startups.
When I’m talking with a startup founder about a possible investment I’m trying to find out a few things: team, scale, timing, product, developer flow, stickiness.
How much energy does cryptocurrency use?
Published in Data Center Energy, Environment, IT Energy.
Is cryptocurrency / Bitcoin bad for the environment? In 2019 crypto consumed 70-90 TWh of electricity globally, with 60-70 TWh of that from Bitcoin mining. What that means for carbon emissions depends on where the mining happens.
Carbon aware workloads – current status, limitations, and opportunities
Published in Cloud, Environment, IT Energy, Product Engineering.
Why isn’t carbon aware workload scheduling more common? Data center level scheduling is infeasible, so what are the opportunities for developers to implement more granular functionality?
Cloud emissions transparency stage 1 completed – what next?
Published in Data Center Energy, Environment, IT Energy.
Customers should now be asking their suppliers for the carbon footprint of the software services they buy.
Paper Notes – The overlooked environmental footprint of increasing Internet use
Published in Data Center Energy, IT Energy, Paper notes.
The methodology is invalid, which the authors acknowledge but ignore. This means the results of this article aren’t particularly useful.
My favourite books of 2021
Published in Favourite Books.
In 2021 I read 22 books. I track all the books I read on my reading list. Here are the ones I recommend.
Clean energy buying incentives for data centers
Published in Data Center Energy, Environment.
Using a marginal emissions-based sustainability score incentivizes migrating workloads to a region with a lower marginal emissions factor. The emissions factor for that workload would reduce, but does it incentivize the deployment of new clean energy?
Useful calculations – energy vs carbon
Published in Environment, IT Energy.
The ultimate goal is a reduction in emissions, but we can’t analyze improvements without reporting energy per unit of work done.
Paper Notes – Assessing anthropogenic heat flux of public cloud data centers: current and future trends
Published in Cloud, Data Center Energy, Environment, Paper notes.
Data centers are not 100% efficient, so they generate waste heat, which causes anthroprogenic heat flux, and can therefore be linked to global warming. But how much? And should we be concerned?
Dirty data? Carbon footprint of photo storage
Published in Cloud, Data Center Energy, Environment.
An example of poor quality research with flawed assumptions designed as click-bait to get news coverage timed to land during COP26. Deleting a few photos will have zero impact on your carbon footprint.
