Getting a pie card

Today was mostly spent working on comics and then doing more of my Halloween special ethics classes on Witch Hunts this evening.

I took Scully on a walk for lunch, to the pie shop at the station, where I haven’t been for a while. They had two new special pies today: pepper steak with cheese, and butter chicken. So I had to try those, and they were both very good. The woman there asked if I had a pie card, and I said no… they must be new! So I grabbed one and she clipped two of the little pie icons, and then she winked and said, “And I’ll do two more for last time.” And she gave it to me with 4 of the 10 icons clipped. Only six more and I get a free pie!

In the afternoon I decided to take Scully on another walk to get a bit more exercise. But when we got outside the air was full of smoke. Authorities have been doing controlled burns of bushland around the city today to reduce fuel before the summer fire season, and the prevailing wind blew it in my direction. It was quite thick and awful, so we cut short our walk and took a shortcut home. And when I got home I closed up all the windows to prevent the smoke getting in.

For dinner before my classes I made a Moroccan chick pea thing with tomato, spices, and some haloumi cheese. And for a bit of vegetable I threw in some broccoli, though I don’t think that’s very Moroccan. Unfortunately I tasted it and thought it needed aa bit of saltiness, so threw in a stock cube, and it ended up too salty. I should have only used half maybe. But I added some lemon juice and made rice to go with it, and it was okay.

Restarting ethics classes, Halloween witch hunt special

This evening I had my first online ethics class since stopping for a week to make time for last week’s ISO meeting. I wrote the lesson plan yesterday, and it’s on the topic of Witch Hunts, since this is the last full week (Tuesday to Monday) before Halloween. I start with the Salem witch trials to set historical context, and ask some questions about why those events happened and how something so grossly unjust could take place. And then move onto modern figurative witch hunts, where people are accused of something with little or no evidence, and what sort of consequences may occur.

It’s a fairly complex topic for the age group of the kids I’m dealing with, but most of them are pretty bright and I think they can handle it. Except today I had a new enrolment, and I did the full 3-minute introduction to the class, then launched into the backgrounds tory and starting asking questions, and when it came to this new kid she just looked like a deer in the headlights. I had to ask several times if she was thinking, or if she understood the question, or if indeed she understood English, before determining that her English skills were quite rudimentary. I had to remove her from the class, and then afterwards refund the class fee, unenrol her, and write a message of explanation to the parent.

At lunchtime today I took Scully on a long walk, with ball chasing time. She’s missed out a little lately, so it was good to get out in the fresh air for a good long while today.

This afternoon I catalogued and photographed more Magic cards for listing on eBay. A few hundred cards from the Unglued, Unhinged, and Unstable comedy sets, and a few hundred from Throne of Eldraine.

A low key day off

I had grand plans for my day off today. I was going to find some place to go with Scully and spend some time out. But the weather was a bit grim, with light showers giving way to strong winds and quite chilly temperatures.

I searched the net for some place that has good meat pies that I hadn’t tried before, but almost all of the ones filling those requirements were south of the Harbour and in inner city suburbs where parking is difficult. I didn’t fancy dealing with all that. I found a bakery called Berkelo in Manly, but again that is a bad place for parking. But then I saw they had a shop in Mosman, closer to home and easier to park.

So I just went there. They only had two types of pie: chicken or pumpkin. I chose the chicken pie, and a sausage roll. I reviewed the sausage roll (with photos) over on my sausage roll blog. The pie was okay, but nothing to write home about. But then I looked inside again for a sweet treat and they had… almond lamingtons. Like a lamington, but coated in almond crumbs, and filled with an almond cream. I took that away and ate on a nearby park bench. It was delicious.

After returning home, I spent some time making sourdough bread and pizza dough for dinner. And a comic. And… I really don’t know where the time went.

Assessment marking day

Today I got up and went to collect the grocery shopping. I didn’t have time on Friday when I usually do this, due to the ISO meeting, and I forgot to order early enough to pick up on Saturday.

After getting home and having some breakfast I went for my 5k run. Today was the day of the charity 7 Bridges Walk around Sydney Harbour, and the walk route goes very close to my place. I had to choose a running route that wouldn’t intersect too much with the hordes of walkers. Interestingly, at various points along my run, I could see (in the distance) a total of 5 of the 7 bridges: Sydney Harbour Bridge, Pyrmont Bridge, Anzac Bridge, Iron Cove Bridge, and Gladesville Bridge. It was a good day for the charity walk event, as the weather was mild and partly cloudy.

For my run I was surprised to record an achievement on Strava, my fastest 2 mile time. I didn’t keep it up though, as my 5k time was good but not among my best times.

After I had a shower to freshen up I got stuck into marking the image processing assignments for the university course I’m tutoring. This was several hours of work, and I only finished just before dinner. I made a quiche with pumpkin and asparagus for dinner.

And now… tomorrow I have a full day off when I can relax and do nothing work-related! It’s usually my busiest day with online ethics classes, but since I cancelled a week of them to fit in my ISO meeting, I have none tomorrow, and will restart on Tuesday. The weather tomorrow looks decent, so I might spend a day out with Scully somewhere.

Oh! Also today we let Scully do another painting. This is a “dog painting” kit we got some time ago from my sister-in-law. We did the small canvas a while back, but finally decided it was time to do the larger one. You smear it with paint, seal the canvas in a plastic ziploc bag, the outside smeared with peanut butter, and then let Scully go to town licking it. Here’s what she painted:

Sydney ISO meeting: Day 4; D&D night; marking day

Friday was the last day of the IOS Photography Standards meeting. We had one technical session on camera image information capacity. The goal of this project is to come up with measures that can be calculated from the pixel statistic that reflect how well the image supports machine vision tasks such as object detection to be performed. This is a very different measure from image quality for humans. The use case is similar in fact to the machine vision standard I mentioned on Day 1, but here we’re using measures such as the Shannon information capacity.

After that we had the closing administrative sessions, going over action items, finalising plans for the next meeting, adopting resolutions, and paying thanks to the various organisers and hosts (which includes me this time!).

I came home about 2:30pm and got straight into housecleaning to prepare for the Dungeons & Dragons game in the evening. I vacuumed, cleaned the shower and bathroom, and had a shower to freshen up. Friends arrived at 6pm and we played the next session of our current adventure. Much fun was had, and we finished up around 10:30.

Today I got up, had breakfast, went for a 5k run. I didn’t do as fast as last weekend. It was warmer and more humid, so it was a bit tougher going. After a shower I made a new Darths & Droids strip for tomorrow.

Then I got stuck into marking student assignments for the university image processing course. I have seven groups to mark, and got through three this afternoon. Hopefully I can polish off the last four tomorrow.

Sydney ISO meeting: Day 3

This morning I dropped Scully off at doggy daycare again. They were going to deliver her back at home in the evening after my wife got home from work. Then I hopped a train into the city. The weather was lovely today, mild and sunny.

The ISO Photography Standards meeting today went through a bunch of different technical topics, covering: camera readouts and controls for HDR photography, camera memory model, digital camera pixel specifications, ISO DNG file format, low light performance with hand-held camera shake, depth metrology, image flare, and image stabilisation. We also had some additional discussion on the HDR topics covered yesterday, because there had been a failure to reach consensus on some issues. This was a… lively session.

After the meeting I headed home, where Scully still had not been delivered by the doggy daycare place. Then my wife got a message saying that she’d been delivered to her work! They’d messed up the address, and then left her with some of my wife’s co-workers, rather than try to contact us. So she requested they pick her up and bring her back home, but she also left to walk all the way back to work in case they took too long, while I stayed home in case she arrived here. I called up to find out what was going on and they said the delivery driver was a few suburbs away and because of the major crash on the Bridge traffic was banked up everywhere and it would be at least an hour before they could get back to my wife’s work. So lucky she left to go back there.

She arrived and fortunately Scully was safe and sound with her co-workers. But she had no harness or lead, and so couldn’t walk home with Scully! So I had to drive down and pick them both up.

I had a call with the doggy daycare and they were very apologetic, saying they’d already spoken to the delivery driver about leaving a dog with someone who wasn’t the owner. That absolutely never should have happened, no matter what the co-workers said, without contacting and checking directly with us. So it was all a bit stressful because we didn’t know for sure that Scully was safe for half an hour.

To end on a more positive note, some photos I took the past few days while on break from the standards meeting. First, the view from our meeting room window, with a coveted Sydney Harbour water view:

Sydney ISO meeting: Day 2

I got up this morning and after breakfast headed into the city for day 2 of the ISO Photography Standards meeting. The weather was better today, with a bit of sun poking through the clouds, though it go greyer in the middle of the day. Late in the day the sun came out again and it was a beautiful early evening.

The technical discussion today was all about high dynamic range (HDR) image representation, covering aspects of how to specify conversion to standard dynamic range (SDR) displays or print renderings, how to edit HDR files that contain metadata specifying the creator’s artistic intention on different display media, and so on. It was very technical and not my area of specialty, so a bit less interesting to me than tomorrow’s other technical topics.

One interesting point that came up about converting HDR images for SDR display: If your software/hardware can’t render the HDR content adequately then there is a potential privacy or security issue because users might then share an HDR image that contains visible data that they can’t see on their display, and so would be unaware of. This is the sort of consideration that we have to think about when devising standards to deal with this sort of stuff.

We broke early at 4:30pm because I’d organised a behind-the-scenes tour of the Art Gallery of New South Wales. We met there at 5:30, allowing some delegates time to drop gear at their hotel rooms. We were met by a staff member who is also on the Australian photography standards committee, and she showed us around the gallery photo labs, demonstrating equipment used to digitise artworks and telling us about their program of photography and digitisation, the unique challenges they face, and so on.

After this we separated, with many of the international delegates taking the opportunity to explore the Art Gallery (which is open until 10pm on Wednesdays). But I headed home on the train, getting home a bit before 8pm.

My wife had already had some dinner, so I cooked up some mushrooms on toast for a simple dinner.

Sydney ISO meeting: Day 1

Today was day 1 of the ISO Photography Standards meeting here in Sydney. I had a chore to do first thing in the morning, dropping Scully off at doggy daycare, since me and my wife would both be out all day. This would have been fine, except it was absolutely pouring rain, and the nearest parking to the daycare place is not very close. So I got pretty wet, and then had to dash back home and walk straight to the railway station in order to make it to the meeting in time. I got there with my trousers wet from the knees down.

I met the overseas delegates and made many apologies for the weather. There was a good turnout, and we got down to business with the opening administrative session. Then later we had technical sessions on vocabulary, for proposing and deliberating definitions of standard dynamic range (SDR) and high dynamic range (HDR) imaging environments. There are no standard definitions of these, so we debated the technical merits of several proposed wordings, and although we reached rough agreement there was still some dissatisfaction. But we will produce a draft document and it will go through rounds of commenting, so it can be further refined.

The other technical session was a new one on machine vision cameras, with a proposal from the European Machine Vision Association to submit one of their standards for characterising image sensor quality for ISO adoption. This is very different from our usual photographic use case, because for machine vision we don’t care about human aesthetics. For example: periodic noise patterns in images are extremely distracting to humans, but quantitatively are not different from random noise in a machine vision application. So the noise calculation formulae are very different.

We finished just a few minutes early and I headed home. I made enchiladas for dinner, and made a new Darths & Droids strip for Thursday, since I won’t have any time tomorrow.

Late and busy Monday before ISO meeting

Phew. It’s late. I did my last six ethics classes today. In between I packaged up some more Magic cards to send off to a buyer. I had to go to the post office, but a big thunderstorm broke over Sydney mid-afternoon, the only time I had spare time. So I drove up to the post office with Scully instead of walking through the rain.

I made pizza dough, to be topped with stuff for dinner. And a new Darths & Droids comic for tomorrow night.

And I did some prep work for the ISO Photography Standards meeting which begins here in Sydney tomorrow. We’ll have about 30 delegates from around the world attending and I’m on hosting duties. We’ll be meeting 9-5 for the next few days. So I’ve cancelled ethics classes for the coming seven days to allow me to do this.

And on top of this, I have to start marking the first assessment task for the university image processing course! It’s going to be a super busy week.

Lightning fast blog post

It’s late already and time to mention what I did today:

First thing in the morning I made a Darths & Droids strip, because I completely forget to do one yesterday!

5k run: I took it easier than yesterday, considering I’d managed a great time then. And I still ran under 27 minutes today! Maybe I’m getting better at this??

We went out to my mother-in-law’s place for lunch with her and my wife’s brother and sister. Just some chicken bread rolls and catching up with family.

I got home and made sourdough bread, which is now baking in the oven after rising through the evening.

Three ethics classes. Super interesting class tonight. 3 of 4 kids thought it was okay for someone else (not JK Rowling) to write a new Harry Potter book and sell it. One was in China, and she actually said there are lots of these books for sale there. 🙂

In between I made okonomiyaki for dinner.
