Ginowan has a large fireworks show every year. It's normally in April, but due to you-know-what-virus it was postponed to July this year. 

Good thing: we can see the area right from the balcony. So we set up with dinner (homemade rice bowls) snacks, folding chairs and camera with a tripod. 

As it happened, the first typhoon of the season passed by just the day before. The weather was still really bad the same morning, but they insisted it would go ahead as planned. The rain let up literally minutes before it was due to start — a testament to just how good short-term weather forecasts are these days.

The fireworks happen near Tropical Beach and is sponsored by JAL, and by the resort hotel next to it. The view from the hotel is probably pretty spectacular. 

I elected to take just long-exposure shots this time around. Typically 4-10 seconds per shot. You treat the fireworks much like you'd treat a strobe; you control the brightness with your sensitivity and aperture, not shutter speed.

The display was designed by Junko Koshino, a clothing designer. It did feel more focused on creating interesting patterns than on just big explosions. And the long exposures really bring that forward, I think. These fans look as good as a still picture as they did live.

Trees with leaves, I think

 You know, if the 2020's could just stop trying to be "interesting times" then that'd be great....

Moving House

We've moved house. From Naha in the south we've moved about 10km north to Ginowan. From a fun but really old apartment, to a new, fresh place. From a backstreet in the center of a city, to a residential area by the sea.


Ginowan at night. Not a dense city, exactly, but not rural either.

Our entire existence right now is one of cardboard boxes and chaos. We're slowly digging ourselves out from the pile of stuff we've accumulated over the years. My computer is still packed away, so I've got no real pictures to show.

Why move? One reason: the Naha rental apartment was expensive and aging badly, and the landlord wasn't willing to do much more than the minimum necessary. For instance, the water pressure was so low that you'd lose the hot water in the shower if you turned on the tap in the kitchen at the same time. That was always fun in winter when I was showering after work while Ritsuko was making dinner.

Another reason: Our new place is 10km closer to my place of work than the old. But as those 10km were through Naha and Urasoe — very busy during rush hour — that makes my commute about 25-30 minutes shorter in the morning, and 30-60 minutes shorter in the evening. I now drive the 30km to work in only 45 minutes each morning, giving me lots more free time each day.

We also get a nice views, and we're now close to Chatan and Rycom; the Convention Center mall and the seaside park is right down the road; and the Parco City shopping center is only minutes away. 

On the down-side, we lose walking access to the Naha city center, with its restaurants and shops. And we're more car dependent than before; while our new place lets us have two cars, we also need two cars, a mixed blessing at best. Time will tell if we'll get used to it or not.

Here's Osaka

So I start a post about something. I write half of it, then life gets in the way, I focus on other things and I forget about the post. A few weeks pass by and I can't pick it up again because I no longer really remember the point of writing it. 

But it's still sitting there, silently waiting for me to finish it. The guilt I feel for not doing it stops me from writing anything else - which is ridiculous of course. I'm the only one who even knows what I was trying to write in the first place.

So forget about that. We've been to Osaka, both over New Year and Golden Week. Here's a few pictures, selected not because they mean anything, but just because I like them:

The old Osaka City Hall on Nakanoshima. Today it's a conference center, and the surrounding park is a popular place for festivals and events. The new Osaka City Hall is a grey concrete box just off to the right.

Umeda JR station in Osaka.

Vending machines — is there anything they can't sell? This one sells COVID antigene tests for 1900 yen, less than 50 meters from home.

This way.

Namba, Osaka. This is obviously a story in the making, and I really want to know what was going on and how it turned out.


Kawachi-Nagano is less than half an hour away from Namba by train, but as quiet and peaceful as you'd ever want. Feels like going 30 years back in time, in a very good way. A friend of ours works at a ryokan in the area, so we went there for a delicious lunch.

The pinball hall in Big Step, Amermura. Almost a hundred machines, from really old to the newest releases. Well worth a visit if you've ever enjoyed pinball. Even more worth it if you've never done so. Bring 100 yen coins!

Lilo Coffee Roasters is currently my favorite coffee place in Osaka. They do some excellent specialty coffee. You can get your choice of beans brewed almost any way you want, and buy a bag home.

A quiet evening sit down outside the shop. Minamisenba.

You never really see your neighborhood until you leave it for a while. Minamisenba.

Life Pro Tip: Don't scratch your car

 Life is full of choices. If you have the choice, I do recommend that you not get too close to a fire prevention cabinet in the company parking garage and scratch the rear of your car:

It looks so small, doesn't it? The rear scratch in the plastic panel is apparently easy to fix; just a bit of paint. The front one is in a metal panel and is dented as well as scratched. That got expensive.

Now, you might feel the urge to try this, just to find out what it's like. I can assure you that you're not missing out on anything. They need to remove the rear panels (and light fixtures), beat out the dent and repaint the area. Meanwhile I'm driving a rental car to work. 

Insurance covers the rental car but our deductible is too high to cover the repair. Why is it so high? Because we didn't plan to break the car, that's why. 

This is a partial list of things we could have spent the money on instead:

All of which would have been more fun or more useful than putting a scratch on the car.

So, don't scratch your car. Get the toothpicks instead.

Valentine's Day

Like very year, Ritsuko managed to find me something a little special for Valentine's Day. As you probably know, in Japan it's split into two holidays (probably so shops can sell more stuff ^_^) : on Valentine's Day women give a present to men; and on White Day a month later men reciprocate with a gift to women. 

I've received some really cool chocolate-themed gifts from Ritsuko over the years. My all-time favourites have been the Jurassic chocolat and the chocolate tools. This is what I got this year: 

A box of chocolates. And a camera!

A box of chocolates. Specifically, a metal box in the shape of a medium-format TLR, containing chocolates packaged like 35mm film. Really cool, and the chocolate is delicious too. Now, should I keep the metal box to keep stuff in; or do I convert it to a pinhole camera? Both are tempting — the box would be perfect to store film-related stuff; but just imagine taking an actual picture with this! Decisions, decisions...

Work From Home (again)

Omicron is spreading like wildfire in Japan as elsewhere, and Okinawa is hit by far the hardest. This is in no small part due to the American military bases, and the lax-to-nonexistent procedures they have had for entering the country from the US. 


COVID cases per day in Okinawa prefecture. That vertical wall at the right edge is not reassuring...

Okinawa is also the poorest prefecture in Japan, and has the smallest number of hospital beds per capita ("hospital bed" means not just the bed, but equipment, staff and so on). Even though the number of cases have been — and remain — low by international standards, there is a real risk that the medical system will be overwhelmed by the number of cases. If that happens, people that need emergency care would start getting turned away. That would be very bad.

Among other measures, the prefecture has now requested that businesses implement work from home policies to reduce the spread. And as OIST is really good about following regulations, and is taking COVID very seriously (my bosses' boss, Mary Collins, is a professor in immunology; the person in charge at OIST for this situation; and really good at getting things done), we are back to working from home again from today and for the next two weeks at least.

Naha harbor, and typical Okinawan winter weather.

I'm not going to dwell on the larger picture here — lots of other people have a better grasp of things than I do anyway — so I just want to jot down some notes on what has been working for me in this situation. I'll also add some random pictures because why not.

The greatest thing about working from home, for me, is my commute. Or, rather, the lack of one. Normally I spend 1 hour and 10 minutes driving to work, and 1 hour and 15-45 minutes going home. Now I spend about 5 seconds walking from the living room to my desk in the backroom. That's about 2.5 hours of my life I get back every single day.

Today I woke up at 6:30 as usual. I went for an hour-long run to Omoromachi and back, had a relaxed breakfast, and I still had enough time to do a bit of cleaning up and start a load of laundry before I logged in to start my day.

It's also really convenient to be at home of course. I can make good coffee and make a real lunch, and eat together with Ritsuko when she's at home. She can use the car when she needs to. And I can do stuff that isn't really possible when working at OIST, such as playing music while I work, or noodling on my ukulele while thinking.

The worst thing is the lack of face to face meetings. We have a good group of people at SCDA, and working together with them is part of the fun. But my job also involves a lot of interaction with the researchers. I teach courses on using HPC systems and how to program cluster computers. I also have daily meetings to help them get started on the cluster, give advice about how to best run things, and work with them to improve their code to run faster or better on our systems. This is the best part of this job and a large reason I took this job in the first place.

But that's of course no longer happening. I do use Zoom for one-on-one meetings and classes but it's a pale imitation of the real thing. It's doable, and it sort of works, but it's nowhere near as frictionless, social and satisfying as meeting in person. I miss that.

Fishing is insanely popular here. I've never tried it myself; I worry that I'd get hooked (sic) and have to deal with fresh fish every weekend.

Technically, working from home works OK. I have an improvised  standing desk and a wooden high stool to sit on, but this setup was never intended for using all day long every day. If working from home became a regular weekly thing I would need to get a real desk and a proper chair.

I connect my work laptop to my monitor. It's a largish 32" 4K LG monitor that's perfect for my desktop. The laptop, with its pokey integrated GPU does struggle a bit with the size; it can only drive the monitor at 30Hz, and while fractional scaling (at 150%) works surprisingly well on the Gnome desktop the combined result is a slight but noticeable delay or hesitancy to everything. For work I only use an email client, a browser and a pile of terminals open to remote machines, so it's not a big issue.

The other technical problem is our network. We do have fiber at home that's technically 1GB/s, but as we live in a mixed building with lots of businesses, and in the middle of the city, the connection is horribly oversubscribed in practice. We sometimes get no more than 20-30Mb/s and even less at night. It's doable but not ideal, especially when I need to talk with people over Zoom.

My ideal for Work From Home would be to do it at my own discretion about 1-2 times a week (you know, when we're not in the midst of a raging pandemic). That would give me a break from my commute, give me some alone time to work — for all that I like people, I'm basically an introvert — and still get the frequent personal connections that makes this job so rewarding.

I'd have a proper desk, perhaps one that can be raised and lowered as needed, and a real desk chair. We'd have an internet connection that sucks a little less. That would make for a nearly optimal experience.
