Last Night In Oz

Friday, January 10th, 2020

I’ve mostly finished packing on this last night of my Australia vacation. I’m absolutely exhausted from endless active days but my mind is full of many happy memories from these past three weeks.

Thanks to my parents for putting up with me for so long. Thanks to all my friends – AW, SMC, KB and MMC – for giving me their time. And thanks to Australia for – as always – welcoming back its emigrant son.

But my vacation is not over, since tomorrow I fly to Japan where I will stay for the next ten days. If you’re wondering what I’ll get up to… so am I! You can bet the otaku madness will be unfettered though, so look forward to lots of weird and wonderful on this blog (hopefully) every day starting tomorrow…

The Stuff That Had Anakin Panicking

Monday, December 30th, 2019

I went for a big long walk today along the beaches, and I thought many things. One of those things – and it’s something I’ve thought before – was just how many sand grains are actually on this beach?

Let’s work it out.

That’s Newcastle beach. It’s gently curved, 650 meters long and as best I can estimate using satellite photos, has about 140 feet (~42.7 metres) of sand width. Estimating the depth of the sand is difficult, so I’ll go with a likely conservative average of 2 metres.

Doing the math gives a volume of sand of approximately 55,500 cubic metres. However all this volume isn’t occupied with sand, since there’s gaps between the grains. To work out the actual volume of sand the packing constant (ie what percent of the volume is the media of interest) is needed.

This is difficult to calculate. In fact it’s very difficult since the grains are of varying size and shape. So as an estimate I’ll assume they are spheres (they’re not) and that the sand is mostly settled which gives a value of about 74%

So that gives us about 41,000 cubic metres of sand grains.

Now to calculate how many discrete grains. Once again approximations are needed. The sand on Newcastle beach is very fine but not silt-like, so we’ll use the industrial classification of ‘fine sand’ and treat each grain as a cube with sides 0.25 millimetres.

Diving the total volume by the volume of a single grain gives us a final answer: I estimate there are at least 2.624 quadrillion grains of sand in Newcastle Beach.

To put that into perspective, that’s about 340,000 grains for everyone on Earth, which would fill a volume about as big as a golf ball. So yes, everyone on earth could easily take a handful of sand from just Newcastle Beach without it running out. In fact there’d likely be a lot left over since I probably overestimated sand grain and underestimated depth.

And that’s just one beach. Australia has over 10,000 of them πŸ™‚

2019 in Games

Saturday, December 7th, 2019

Another year, another ‘Year in Games’ blog post. It’s still my #1 hobby, and in some ways I’m more invested in it than ever. But it’s interesting to see how my spending (and playing) has changed over the years, moving ever-so-slowly more toward replaying old stuff than buying new.

In 2019 the numbers dipped upwards slightly this year, with 57 games bought for 10 systems at an average cost of about $25. The PS4 led in terms of games purchased and total dollars spent, but much like last year a decent amount of my spending was for retired (and in some cases distinctly retro) systems. Here are the charts, in another new format to please my critics:

The above is a proportional plot of games purchased by system. Yes your eyes don’t deceive you: I bought one game each for the Commodore 64 and PC-Engine in 2019. I can’t play either since I don’t own either system, but both were Wizardry games and I collect them so how could I pass them up? In fact more than a third of all my game purchases this year were for retired systems, and even more if you include the 3DS which is very much on the borderline these days.

And that is the breakdown of dollars spent. The 3DS has a large block since I bought an actual new 3DS system this year (which was my sixth…), and you’ll note that even though I bought more GBA games I spent more on the C64 and PCE games. This is because one of the GBA games was a mere Β₯65, which is about US$0.60! The average game price remains low since I very rarely buy any new releases these days, instead waiting 6+ months until they inevitably drop in price. On Black Friday I bought nine PS4 games – all released within the last year – at an average cost of $18!

Despite the retro gaming (I’m not mentioning here the hours spent with the NES, SNES, C64 and Genesis Mini) I sunk a massive amount of hours into some extremely high quality new games as well. The following three were amongst my favorites of the year:

Monster Hunter World: Iceborne (PS4)

What can I say? Will there ever be a year a new Monster Hunter game doesn’t make this list? Iceborne – the expansion to world – added a higher difficulty, oodles of new monsters and lots and lots of fun. It was even better than World, and given they’re still adding content I doubt I’m done with it yet!

Nioh (PS4)

Imagine a hybrid of Dark Souls and Monster Hunter and this is what you get. An absolutely fantastic mission-based fuedal Japanese monster hunt, that has incredible amounts of content and oozes flavour. A wonderful, wonderful game and I look very much forward to the upcoming sequel.

Hollow Knight (PS4)

A ‘metroidvania’ set in a world of bugs. At times very difficult, but with a gigantic map and lots to see and do. I got lost in this one for weeks, which wasn’t bad for a digital game that cost me only $5!

I can’t end the year without a final farewell to the 150+ games and consoles that I parted with back in June. I ‘ve not regretted it and don’t miss them, and I very much hope they’ve gone on to new owners and are now featured on someone else’s “2019 in Games” list :

Snowpocalypse 2019

Tuesday, December 3rd, 2019

In the last 48 hours we received a lot of snow. I took regular photos from the same angle to show the accumulation. Here they are:

The above three run from noon to about 5 pm on Sunday. The snow was falling lightly at first, but picked up after nightfall.

The above is a 10 pm shot. It looks brighter than the 5 pm one due to the remarkable low light camera mode of my new iPhone. You can clearly see the snow has been coming down since the last shot: the driveway is barely visible here.

Above shows 6 am Monday morning. According to the weather service we’d received about 16 inches (~38 cm) overnight, and it was heavy snow which proved difficult to remove. Down near the street it was as deep as our snowthrower can handle, and although we have a powerful machine it really struggled.

That’s immediately after we finished clearing the snow. It was still falling lightly at this point. Although it was Monday almost everything was cancelled and we were both staying home for the day.

By around lunchtime not much had changed. The footprints were from the postman, who isn’t stopped by ‘a bit’ of snow!

By evening though (this is around 8 pm Monday) you can see it had built up somewhat again: there had probably been another 3-4 inches by this point.

And then we woke today to this: another 6+ inches since yesterday. Once again it was tricky to remove due to heaviness and the cold (it was -4 C) but at least it had stopped falling.

And here’s the final shot, after we had finished this morning. All told the official tally is 22.6 inches of snow (57.4 cm) in Albany and slightly more where we live just to the south. It was the 8th biggest snowfall of all time in this city. I expect well remember it for a while πŸ™‚

Lunar Module

Sunday, November 24th, 2019

As soon as I saw the above in the LEGO store window I had to have it.

It was built in three stages; the lunar surface first:

Of course I had ‘help’ πŸ™‚

The descent stage was next, and was a lot of fun to build including a lot of ‘metallic’ parts.

It also contains lots of little details, including a tiny model laser reflector, which I often use in examples during one of my lectures!

The finished Lunar Module:

It’s a fantastic kit, and one of the most fun LEGO builds I’ve ever done. I give this my highest LEGO score πŸ™‚
