ASA statement on p-values

There has been controversy around p-values in recent years, often linked to issues with reproducibility in psychology.  p-values are also often reported in empirical software engineering papers. We haven’t yet seen widespread public controversy about software engineering studies, but that’s not because there aren’t problems! The American Statistical Association has just released a clarifying statement …

More Philosophy of Engineering

In January, the the journal Synthese accepted and published the first of two papers of mine on the philosophy of engineering.  The second installment is now also accepted and published: “Critical rationalism and engineering: methodology” (author’s preprint here). Woot!  In the new paper I use the three worlds schema from the first paper to look …

Moving to Saluda Medical

Today I’m starting in a new role as Systems Engineering team lead at Saluda Medical – a medical device startup company. We’re working on a new technology for closed loop control for spinal cord stimulation that will target the treatment of Chronic Neuropathic Pain.  This is a great group of people and a technology with …

Philosophy of Engineering

What is engineering? Sometimes people think engineering is just the same as science, but in a new paper on the philosophy of engineering (preprint here), I argue why that’s not the case. Engineering is similar, but different to Science, and its epistemological issues are also similar but different. I got into this question because of …

Heritage Lager Again

Wow – more than a year between homebrews, again. I’ve almost depleted my stores, which gives you some idea of how much I’ve been drinking and socialising over the past couple of years (not much of either). I find old homebrew basically gets better with age, but maybe I’m pushing it with some of the …

Heritage Lager

Almost a whole year since my last brew (which has worked out great, BTW).  Inspired by a colleague’s homebrew at Friday afternoon drinks, I’ve dragged a kit off the shelf to start another brew.  This time it’s a Cooper’s Heritage Lager, with 600g Dextrose and 400g Maltodextrin.  Nothing fancy.  O.G. is somewhere around 1.042 to …

What Software Engineers Should Know

Software Engineering would be a more mature discipline if we had spent more time reading What Engineers Know and How They Know It: Analytical Studies from Aeronautical History rather than A Pattern Language: Towns, Buildings, Construction.

I was an Apple Mac kid

Don was an Apple II kid, and he credits Apple with helping him dive so deep and so early into writing software.  I never had an Apple II, but I got a taste of that kind of experience with the Vic-20 at home, and the BBC computer room at school. But then, we upgraded our …

Mandarin and Coriander Wheat Beer

Something to do with all the mandarins from our tree – a Hoegaarden-inspired mandarin-and-coriander wheat beer.  Cooper’s wheat beer kit, light dry malt, peels from 6 mandarins, and 2.5 tblsp coriander seed.  (All a guess – let’s see how it turns out.)  O.G. is 1.040.
