Fog and cheesecake

This morning dawned cold and foggy – the first significant fog of the year. My wife suggested I take a photo to put in this blog, but I neglected to and now I’m kind of regretting it. But we have more forecast for tomorrow, so if there is I’ll try and get a photo then.

In other non-weather atmospheric phenomena we had two interesting astronomical things happen overnight, visible from Sydney: a significant meteor sighting, and also a brilliant pink aurora australis which was visible as far north as Sydney. Unfortunately I was asleep for both. But I’ve been enjoying the views of Scorpius directly overhead late at night when I take Scully out for her pre-bedtime toilet.

Monday is always my busy day with lots of online ethics classes to wrap up the week’s topic. It’s been an interesting one on names, with plenty of interesting questions that I rotate from class to class to keep it fresh for myself.

In between I marked another university Data Engineering assessment report. A student team studied potential predictors of the length of stay in hospital for cardiac patients, from among variables such as: vital signs during initial triage; levels of haemoglobin, blood oxygen, and electrolytes in an initial blood test; demographic data such as age, sex, ethnicity; and also insurance status. They used publicly available data from over 265,000 United States patient admissions, collated by the Beth Israel Deaconess Medical Centre, Boston—the MIMIC-IV dataset, downloadable from physionet.org. Note especially that this is data from the United States.

After doing various regression analyses, they discovered that the strongest indicator of a longer stay in hospital was… being non-white. The second strongest indicator was a low blood haemoglobin level at admission. Although the actual correlations were quite weak in all cases.

AT lunch I walked Scully up to my wife’s work to drop her off for the afternoon. On the way home I decided to pop in at the cake shop nearby and grab something. I got there about 1:40pm, and was surprised to see the cake displays completely empty. They’d packed them all away already, in preparation for closing! My wife and I always comment how silly it is that cafes in Sydney all seem to close at 2pm. It’s really weird… it’s virtually impossible to find a cafe anywhere in Sydney that is open later than 2pm. They seem to think all the business is for the morning rush and lunchtime, and nobody is interested in coffee or cakes after that.

Anyway, I expressed surprise and told the woman in the cake shop that I had wanted to get a slice of cake. She said she could go get one for me and asked what I wanted. So I decided on a slice of cheesecake. She dashed out the back and returned with a slice for me. And then probably proceeded to close up shop as soon as I left.

I took the slice home on the train and ate it at my desk while I marked the above student report. I needed the sugar to get through the day!

  1. So where do you go if you want to spend time outside in a café-like setting in the afternoon or in the evening? Pub or restaurant?

    Sounds a bit strange, though here many cafés close at six o’clock in the evening, which has often felt a bit early to me.

    1. Yes, pretty much. There are also “cafe-restaurants” which are a kind of hybrid, offering cafe service but also full meals, which stay open into the evenings.
