New air conditioning

With the three-day mini-heatwave over, we had our new air conditioner installed today. The workers arrived around 10am and said they’d take a couple of hours, but in reality it was close to three hours of work to get the old unit removed and the new one put in.

The new unit is so much quieter than the old one, it’s astonishing. The old one interfered with things like watching TV, but the new one is so quiet it’s virtually unnoticeable. I suppose upgrading after 20 years was something we should have considered even before the old unit broke. The new unit will use less electricity too.

While they were installing it, I wrote a plan for the older kids’ ethics class this week, on Colonisation. I reused some of the later questions from the younger class on Exploration as the introductory questions for this one and added some more advanced material to the end, so it was quicker than normal.

And in further positive news, my wife is feeling much better after recovering from her illness of the past two days.

Oh! And I got a shipping notification for a Kickstarter project that I backed in… 2015! Yes, they’re actually shipping, 7 years late. A Dungeons & Dragons adventure, so I should still get some use out of it. (My friends asked me if it was something like a USB-1 compatible device or a CD case or something.)

Home care

It was warm today, not nearly as hot as yesterday – 33.5°C. But overnight the temperature didn’t drop below 22.4°C, and today started overcast so it was more humid than yesterday. We still have another day to wait before our new air conditioner is installed. And as a friend said, once it’s installed it probably won’t go above 25° for the rest of the year…

My wife was still sick, and I took her to see a doctor. The doctor said it was a stomach infection that she just had to ride out, and told her to take oral rehydration fluids, so we picked up some tablets from the chemist. This evening she’s starting to feel a bit better, but still not very well.

I finished writing my lesson on Movies, and did three classes tonight. It’s definitely a fun topic – the kids love talking about movies.

Hot and not cool

As forecast, the temperature was 38°C today, making it Sydney’s hottest day since 26 January 2021. The really bad part is we’re in the middle of a four day gap between our air conditioner breaking and the new one being installed. So we had no relief inside at all. I just kept the windows and blinds closed all day to try to keep the heat out, but the thermometer inside still got up to 27°C.

It’s now after 9pm and I’ve just opened the windows to try to cool things down, but it’s not clear if it’s still warmer outside. And I think there’s zero breeze.

My wife is sick too, with some sort of stomach bug. I called in to the university and told them I couldn’t come in to tutor the Data Engineering course today, having to stay home to look after her.

I did my last three classes on the ethics of being offended, then I tried to take advantage of being home in the afternoon to start work on this weeks new topic: Movies. But with the heat and making sure my wife was okay, I only got about half of it done.

It’s going to be a long and hot night. The hourly temperature isn’t forecast to drop below 27°C until after 2am.

Fruit classification

Well, the weather forecast for Monday has been increased in temperature to 38°C for Sydney. Which is going to be the hottest day here for over 2 years (because of the unusually cool weather we’ve been having due to the La Niña for the past few years). Good news: our new air conditioner has been delivered. Bad news: it still won’t be installed until Wednesday. So, we’re stuck without a functional air conditioner on the hottest day for over 2 years. It’s not going to be fun here tomorrow.

Today I assembled a week’s worth of Irregular Webcomic! strips, and wrote and made a new Darths & Droids strip. I also planned some new future lessons for my ethics classes, which in a few weeks will tackled the topics of Photography (for ages 10-12) and Death (ages 13-15).

And for a bit of fun today I drew up a diagram of fruits by botanical definition. This is a long-standing humorous topic between me and my friends, when we point out that various things are or aren’t fruits by various definitions. I was prompted to actually make a list and then a diagram by my current reading of Harold McGee’s On Food and Cooking, which contains technical information about many foods.

So here’s the diagram:

Diagram of fruits

The groupings are by botanical definitions. The green line encircles what people generally refer to as “fruit” in culinary terms. I showed this to some friends and got the comment that they didn’t consider avocados to be culinarily a fruit. I was a bit surprised. I don’t eat avocados myself – they’re one of my least liked foods – but I did have the impression that most people considered them to be fruits. (I consider them to be horrible slimy things.)

They also questioned rhubarb. Now I don’t mind rhubarb, but I’ve never bought it or prepared it myself. I personally don’t consider it a “fruit” in a culinary sense (because it’s so obviously a stalk), but I’ve read that a lot of people do, which is why I included it in the green curve.

Water damage x2

Friday was a hectic and slightly disastrous day. I started picking up the weekly groceries from the supermarket. When I got home I discovered that the ice cream I’d ordered online was missing from the order. In hindsight, it was a prelude to a bad day.

After my pre-lunch ethics class, I drove over to my wife’s work to pick up Scully. I needed to refuel the car on the way home, and the shortest route past a petrol station went by the Naremburn bakery, so I decided to stop in there for a little while and grab another of those delicious cheesecake tarts that I’d had on Thursday.

As we left, it started to sprinkle. We got back in the car without getting too wet, and I drove to the petrol station to fill up the car. By the time we left, the rain was heavy and getting heavier. It was now I realised that I’d left all the windows open at home, since I hadn’t expected it to rain when I left. The petrol station is only about a kilometre from home, but we got stuck in some traffic and caught at a couple of red lights, and it took longer than usual to get home. I ran inside and found the rain had come in the bedroom window, soaking the carpet, some piles of clothing, and a wooden storage chest.

I spent about the next hour cleaning it up, soaking up the water with towels, moving the furniture to get behind and underneath it, then wiping things down with weak bleach to discourage mould growth. By the time I’d done, it was only ten minutes until my next ethics class – and I had three in a row, so I knew I wouldn’t be able to take Scully out if she needed to toilet. So I grabbed her and rushed downstairs to try to get her to go before the class. Fortunately she went quickly and we rushed back upstairs. By now the sun had come out and the air was getting steamy and humid. So I closed all the windows and turned the air conditioner on.

I did my three classes in a row. In quiet periods I thought I could hear some sort of intermittent plinking sound from behind me. My wife has recently brought home a bunch of pots from her beginners’ pottery class, and some of them are pinging with the glaze under stress from the firing (apparently this is a common thing). So I thought it might be that, and I was too occupied with my class to check more closely.

After the last class I finally took my headphones off, and heard the noise again. It didn’t sound like the pinging, but more like dripping. After hearing a couple more drips I located it… It was the air conditioner unit mounted on the wall above the bookcase, dripping water onto the bookcase! I quickly turned it off and grabbed more towels and a chair to stand on, so I could mop up the water that had pooled up there. And then I noticed the drips were going down behind the bookcase, between the furniture and the wall as well!

I got some plastic containers to catch any further drips, then got a strong light and a mirror so I could see down behind the bookcase to check how much water was down there. I really didn’t fancy having to empty the bookcase, move it, and dry the wall and carpet. That would have been an all-day job, since it’s a very large and heavy bookcase – taller than I am and about 2 metres wide, full of books. Fortunately it didn’t look very wet down there. A bit of water had run down the back side of the bookcase, but it was already drying, and it hadn’t penetrated to the front where the books are. Rather than spend all day Saturday moving the bookcase… I think I’m just going to leave it and hope it dries out.

After all that I needed to relax, and spent the rest of the evening playing board games online with friends in our weekly game night. I was a little frazzled and didn’t do very well at all, but at least it relaxed me a bit before bed.

Today, Saturday, I went for a 5k run in the morning. Then I spent the rest of the morning working on the game design for the Creative Thinking course. I told the student I’d get the game to her before the weekend, and fortunately I had a few hours since she’s in the USA and it was still Friday evening there. I had to iterate a lot as I wrote up the rules and created cards for cutting out, when I kept realising certain things wouldn’t work. Eventually I got it in a workable state (I thinK!) and finalised the file and sent it off.

This afternoon I went to the home appliances store to oder a new air conditioner. I might have been able to fix the current one, but it’s actually over 20 years old and I’ve been thinking about upgrading it to a more modern unit for a couple of years already. So rather than risk more dripping water, we decided to just go ahead and get a new one. I bought a unit and organised installation for this coming Wednesday.

Unfortunately… that means we won’t have it in time for the forecast next three days, which the Weather Bureau is warning will be the three hottest days Sydney has seen for almost a year. The highest temperature Sydney had all summer was barely above 30°C, but now we’re into autumn and the next three days are forecast to be 33°, 36°, and 34°. Great.

Walking in Japan

Today I finalised with my wife our plans for doing some walking in the countryside in Japan. With some research, I found a walking trail that is part of the Nakasendō, one of the five Edo Period trade routes. The segment we’re planning to do can be accessed by train, starting from Nagiso and ending in Nakatsugawa. I found us a small hotel in Nakatsugawa, where we can spend a night after arriving from Kyoto, then the next day get the train to Nagiso and walk back over the old Nakasendō route and spend another night before heading to Tokyo. It looks like a really nice walking trail, and I’m really excited about it. Now I just need to find hotels in Kyoto and Tokyo and our trip is fully booked.

Today I spent time working on the game design for my Creative Thinking class, to get it done and a file sent to the student by tomorrow. I bounced ideas off my friends via Discord chat and we decided it would be cool to have every player be a different kind of infectious monster: zombies, vampires, werewolves, etc. They’re all trying to kill humans, but end up infecting each other, so by the end of the game all the players will be zombie-werewolf-vampires and so on. I still need to bed down a few rules and then get it ready to play tomorrow.

Also I had my first class for this week’s advanced ethics topic on Artificial Intelligence. It was a great discussion – all the kids really interested in the topic and talking about the issues. We could probably have easily continued for another hour, but I had to cut the class off at the scheduled time.

For lunch I took Scully for a walk to the Naremburn bakery and had a lamb pie. They also had yet another new dessert: a cheesecake tart with pistachios. I had to try that, and it was really good.

Another busy day…

Today I had to concentrate on writing a new lesson for the older kids ethics class – this week on the topic of artificial intelligence. There’s a lot of potential material for this topic and lots of discussion questions. I had plenty written out and had about a third of the questions left over after I’df fleshed the first 2/3 out with scenarios and information. So I have heaps of backup material if the classes run short, which I don’t think they will.

Did a 2.5k run this morning, and took Scully for a few walks. And…. oh! I had the 4th class of 6 in my current iteration of the board game design class. The student and I are converging on a design for a game involving players having various fantasy roles, and potentially involving families of vampires competing, or maybe witches and wizards… it’s a bit in flux still. I need to distil it into a workable game design by the weekend and send her the file and rules so she can playtest it with family ad friends before next week’s class.
