Some thoughts on the Cost Disease

Saturday 18 February 2017, 06:40

The lovely and talented Scott Alexander has a posting on Cost Disease: the costs of some things, notably education and medical care especially in the USA, have increased in the last few generations to a really unfathomable extent. He gives detailed statistics, but it's typically about a factor of 10 after accounting for general inflation. Why has this happened? He gives some hypotheses, and in a followup posting shares some ideas contributed by readers, but it's not at all clear what's going on. And it seems like knowing might be valuable, because the fact of this phenomenon's occurrence (whatever the cause) is causing a great deal of misery for a whole lot of people, bearing on many other important issues.

I don't know either, but it made me think of some things.

Here's another update on what's up with my new life and new business. In general, there's progress being made, but I'm still facing a lot of annoying delays.

Modular synthesis intro, part 3: How to get started

Tuesday 31 January 2017, 10:56

I will assume that you've already read part 1, which describes what a modular synthesizer is; and part 2, which says that you shouldn't buy one. Your spouse isn't allowed to kill me because I did warn you, and your cat has already formed an opinion on your intelligence anyway. In this final installment I'm going to offer some suggestions on how to get started with modular synthesis. Very much depends on your own reasons, which are ultimately known only to you, for why you've decided to do this. I can only offer some insights that may be helpful for what I think are typical newcomers.

Modular synthesis intro, part 2: Don't do it!

When I started the market research for my business, I put together a profile of who'd be buying my products. I imagined my customers as the kind of people I've met in the modular synthesis hobbyist community. These are people with a fair bit of disposable income (typically because of having California "tech" jobs and no family except cats), who already have medium to large modular systems worth $5000 or more. They are already familiar with the concepts, have been doing modular synthesis for a few years already, and are looking for something extra to add to their existing installations.

Modular synthesis intro, part 1: What is it?

Thursday 19 January 2017, 13:15

My mother asked me to explain what I'm up to in one sentence, for inclusion in the annual Christmas Letter, and I said that I'm making electronic musical instruments. That's a pretty good summary as far as it goes. But people often want more detail on what modular synthesizers are all about, and this is the first of three postings I'm writing so that I can have a place to which I can direct the curious. In this episode I'll summarize what modular synthesis is. Next time, I'll explain why you shouldn't get involved in modular synthesis, and what to do instead. And in part 3, I'll give some advice on how to get started with modular synthesis, for those who foolishly ignored part 2.

I may update these postings a bit in the future, if they prove to have any lasting value. And as a reminder, my company is North Coast Synthesis Ltd., and I'll some day soon be selling synthesizer modules from my Web storefront, which is not open yet. You can register your address on that page if you want me to send you an email when it opens.

Introducing North Coast Synthesis Ltd.

Wednesday 11 January 2017, 19:43

The synthesizer project has reached an important milestone: my business is now incorporated, under the name North Coast Synthesis Ltd. The Web site will be at, which currently just redirects to a password-locked Shopify storefront, but will become public and have some real content in the near future. Watch this space, that site, or my Twitter account, for further updates as they happen.

Setting up shop, and shopping

Wednesday 30 November 2016, 07:45

On the 30th of last month, I was on vacation in Hokkaido, Japan. One month before that, I had just arrived in Sweden for a short stay between leaving my apartment in Denmark for the last time and my return to Canada after living abroad for just over two years. One month before that was my last day of work at ITU Copenhagen, and possibly my last day of paid academic work ever, after 15 years in the research business. Now I'm in Toronto writing a Web log entry; and one month from today, I expect to be on the West Coast visiting my family for the winter holidays. Five consecutive 30ths in five very different geographic and cultural spaces.

Quick thoughts on the US election result

Wednesday 9 November 2016, 14:58

Well, I'm disappointed. And I'm more than a bit surprised, but not another whole bit more: I'm 1.89 bits surprised. That is the negative logarithm to base 2 of 0.27, which was the probability put on a Trump win, and the best estimate available to me of how likely it was to happen. Flip a coin twice and get heads both times, or draw a card from a 52-card poker deck and have it be a heart? Either of those is 2 bits worth of entropy (that is, of surprise), slightly more surprising than last night's main result. Not something that should shock anyone for the reason of unlikeliness, not from the point of view of the information we had 48 hours ago. Feel free to be shocked for other reasons.

Moving in

I wrote my previous update on the train back to Tokyo. My trip to Japan was basically over, but I still had a substantial amount of travelling to do.
