The Pinebook Pro

I'm bored.

I'm working at home because of the Corona virus; we've spent our weekends and the entire Golden Week vacation at home because of Corona; my emails, Line and other communication all involve Corona; NHK news and morning shows is nothing but Corona stories; newspapers, Reddit, podcasts, even Steam forums are filled with posts about - well, you know what. My life has turned into the All Corona All The Time Multimedia Extravaganza.

This is an ongoing disaster, it's disrupting all our lives, and we absolutely must protect those who would otherwise die from the disease. But I'm also fed up with the constant media bombardment about something I can do nothing about.

Okinawa has had no new cases for two weeks now, and we're finally preparing to get back to work again from Monday next week. It's probably only temporary of course; the infection rate is bound to bounce back, especially as we are moving into the main tourist season. Oh, and just to spice things up a little bit, the first typhoon of the season is expected to hit us on Monday morning. Not a strong one, but still - we got a million problems, why not add a typhoon?

I'm bored. Let's talk about something else.

Such as things I get in the mail.

A package! for me — I wonder what it could be? Oooh, it's a computer! "Pinebook Pro". It certainly looks very slick.

Around the time we moved to Okinawa three years ago I got myself a HP Spectre 360 for a lightweight, high-performance laptop. It was light, fast and beautiful. It was expensive — and as fragile as a Faberge egg.

About a year ago we spilled water on the dining table — not on the laptop, just the table. Some of the water trickled its way under the computer, where the bottom fan sucked it inside and promptly killed the machine. Repairing it would have cost as much as buying a new computer.

That expensive mistake soured me on the whole idea of a laptop for a long while. I've relied on my desktop and my smartphone. But I missed having a portable computer, and when I saw this thing I had to try it out.

The Pinebook Pro

The Pinebook Pro in all it's glory. It looks and feels just as good in real life as it seems in this image. Thin and light, fanless, good screen, good keyboard, metal shell.

In short, the Pinebook Pro is a slim fanless — completely quiet! — 13" laptop with a metal chassis and a 1080p screen; 4GB ram, 64GB eMMC storage, and slots for an SSD and SD-cards; USB A and C ports, a web camera, a headphone jack all the rest you expect from a decent modern laptop. The USB-C port can charge the machine and run an external display.

It uses an ARM processor, it's built to run Linux — and it costs all of $200.

Pine64 produces and sells single-board ARM computers, embedded systems and things like that for end users and hobbyists. But they also do fun projects such as the Pinebook Pro, the Pinephone and Pinetime (a DIY programmable smartwatch — I really need one of these!)

The outside case is metal, and feels like a much more premium device. The screen is decently clear and bright, with no corner fall-off or glare. The keyboard is clackety but feels fine and is absolutely good enough for extended use. It's not at the level of that HP laptop or a Mac, but it feels much higher quality than the $200 price tag would imply.

The CPU is a Rockchip RK3399 ARM SOC. ARM CPUs don't have to be slow — look at the Fujitsu A64FX — but this is a mobile CPU meant to sit in a smartphone. It's a "BIG-little" design, with two faster power-hungry cores, and four slow but very efficient cores. Background tasks can run on the small, slow cores, using very little power, while the big cores will run your foreground work fast.

It comes with 64GB eMMC (flash) storage built in. 64GB isn't a lot and MMC isn't very fast but you're not going to do anything really data-intensive with this laptop. A full Linux desktop installation takes about 4-6GB so almost all of the space is available for your data.

The SD-Card slot lets you boot from an SD card as well as add external storage. You can add a real SSD though an optional M.2 adapter, though it needs to be thin and low-power, and it will drain the battery noticeably faster.

The low power draw and the USB-C port has an unexpected benefit: I can charge it with my USB-C phone charger. When I write this or surf the web the phone charger can just about manage to trickle-charge the device. If I play games or compile software it can't quite keep up. Still, it means I can bring just a single, small charger for both laptop and phone.

Open Source

This is built for Linux and BSD - neither Windows nor OSX will run. As of this spring, the default distribution is Manjaro with the KDE desktop. Manjaro has been a very positive experience for me (and worth a post of its own, I think). KDE is a very polished, full-featured desktop. I haven't used it in years and I'm not comfortable with it for various reasons, but it's easy to replace it with a lighter, less intrusive desktop such as XFCE or even i3 if you like.

There are a number of other distributions available for the Pinebook already. You can easily test any of them by copying one of them to an SD card and boot it on the laptop. I've tried 3-4 different ones already; so far Manjaro — with XFCE or KDE — has been the most polished experience.

The openness extends to the hardware. The Wiki page has instructions on disassemble it and extensive documentation on the internals, up to and including the exact measurements of the case parts in case you want to mod or replace anything.

In Use

With 4GB memory, a mobile ARM processor and MMC storage, this is not a fast laptop. There are things you can't do or won't do with it. But it can do a lot — and at $200 I can literally get ten of these for that HP laptop I managed to ruin. I could break one of these every six months and still come out ahead.

The Pinebook Pro on the beach. I'd hate to take an expensive machine to a place like this, but with the Pinebook I don't worry at all.

I wanted to do a performance test, so as a quick, dumb comparison I picked building and running POV-Ray, a fun, scriptable raytracing program that's open-source.

I downloaded the latest release (, then ran two different tests: compile the POV-Ray source, and run its built-in benchmark test. All were built with GCC 9.3, using the default configuration for POV-Ray ("-O3 -ffast-math -march=native"). I didn't touch the power settings on any system, or tune things in any way.

The compilation is a decent real-world test of a common computing task, and is mostly memory and I/O-bound. The POV-Ray benchmark itself, where it raytraces an image off-screen, is fairly simple numerical data processing. I did briefly consider running some BLAS benchmarks as well, but I don't really see the point. If you need BLAS you need a bigger computer.

I ran these two tests on the Pinebook Pro using the two big cores. For comparison I did the same with my desktop sporting a six year old i7-5820K CPU; and with the four year old Lenovo X260 laptop I use at work.

The Pinebook and the 5820K both have 6 cores, but only two of the Pinebook cores are fast. The X260 has two cores in total (multithreading doesn't count), so I ran all the benchmarks using only two cores.

Compilation (left) and benchmark (right) of the POV-Ray ray-tracer on my six year old i75820K CPU, the four year old Lenovo X260 laptop and the Pinebook Pro. All run using two processor cores.

The Pinebook is about 4× slower than the others for compilation. It's about 2.6× slower than the laptop and 3× slower than the desktop for the POV-Ray benchmark.

This is really not too shabby at all. It's quite good, in fact. The Pinebook is 4 times slower compiling the POW-Ray source, but that's mostly due to the relatively slow MMC storage. An SSD would probably speed this up quite a bit.

For the POV-Ray benchmark — lots of simple math and branches — it's 2.6× slower than the X260 laptop and 3× slower than the desktop. For a slim, fan-less low-power machine like this I'm quite pleased, especially at the $200 price. Just the i7-5820K CPU itself still sells for more than the entire Pinebook Pro today.

As an aside, I'm also surprised how good the X260 laptop is. I expected it to fare worse than it did against the desktop. Now, the desktop has another four cores that will speed up the second test almost three times, but per-core there isn't much difference between them. Welcome to the end of Dennard Scaling. (1)

What You Can't Do

Steam and many games won't work. Closed source software in general is usually built for X86 processors and won't run on ARM computers. The current virus-laden elephant in this particular room is Zoom. I, and many with myself, use Zoom on a daily basis while working from home, but there is no Zoom client available for Linux on ARM.

Some open source games and applications will also be difficult or impossible to run — they may need more memory, a faster CPU or a more powerful GPU than this laptop can deliver. Gimp will run fine but you'll struggle to edit larger images. I wouldn't try to run Blender, Pytorch or Eclipse on it.

Today (May 2020) there are still a few rough edges. The power management is a little flaky, so it doesn't reliably go to sleep, and it uses a semi-low power state when sleeping that will drain your battery in a couple of days. But the laptop boots fast enough that I'm OK with shutting it down when I'm not using it.

The keyboard firmware needs some tweaking — the meta ("Windows") key doesn't work with all key combinations — and the trackpad firmware really needs another round of fine tuning to make it a little more responsive.There is a user-created keyboard firmware available but I'm not bothered enough by the issues that I want to take the risk of updating it.

What can you do, then?

Really, almost anything.

Manjaro is built on top of Arch (again, worth a post of its own) which makes a huge amount of open source software available for the Pinebook Pro. If you are able to build it on the laptop at all, you can probably get it through the repositories. Just about any normal desktop or workstation application — compilers, editors, browsers, office apps, computing tools and so on — are at your fingertips. It would be easy to create this entire post, from editing images and creating the graph, to writing and posting it online (and I partly did).

The Pinebook Pro in its natural setting: a hip seaside cafe with shabby-chic furniture and a good selection of third-wave coffee beans. 

Steam is not available, but a lot of open source games are, and even some closed-source games based on Java or Mono — Minecraft and Stardew Valley included — can apparently be made to run with a bit of judicious tweaking.

For computing, my particular niche in this world, Python and most of its enormous pile of packages work just fine. If you need something Matlab-like, you can get Octave (a Matlab clone), or move to Python or Julia for a more modern, up to date experience. I don't recommend using a tiny ARM laptop for numerical computing, but the fact is that you can.

And really, this may be slow by today's standards, but this would have been a decently fast CPU just ten to twelve years ago, and people did manage to perform serious numerical computing long before that.

A lot of modern productivity tools run in the browser today. Microsoft Teams, Gmail and so on will all work fine on the machine (Teams will take a fair bit of the limited memory, mind you). Youtube videos play OK. I'm sure you can use Facebook, Twitter, Instagram Slack and the rest.

Still missing for me is a way to run Zoom. It's our default video conferencing tool at work, I use it a lot to talk with our users, and there is no Zoom client available for download. It's possible I could get it to work though the Chromium browser but I haven't tried that yet. Of course, I can use Zoom on my phone so the problem is not insurmountable.

I would love a Pinebook version of the Steam remote client. That would let me play any game I own on it. It wouldn't be impossible - Valve has released a version for the Raspberry Pi after all.

Could I use the Pinebook Pro as my only computer? Yes, sort of, if I could also use my phone. But it works great as a secondary machine. I'd be happy to bring it for travel — once we can travel again — without fear of losing or breaking it.

And it exudes a sense of fun that I haven't felt with computers in a long time. Never mind being useful, I just enjoy using this.

1) I ran this test on a node on our HPC cluster as well. It may surprise you to know that a state-of-the art HPC node is no faster than my old desktop per-core. In fact, the cluster nodes have a lower clock frequency so they're slightly slower. 

But clusters aren't built to have very fast cores; they're built to have lots of them. I can use up to six cores on my desktop to speed things up, but on our cluster you can use up to 128 cores in a single node, and tens of thousands if you can scale across nodes. That's where the speed comes from.

Corona, The Work From Home Multimedia Experience

I've now worked from home for three weeks. During this period Japan and Okinawa predictably went from "I'm sure somebody is taking care of it" to "Oh wait, this is actually really bad!".

We're on semi-voluntary lockdown and telework until the end of May at this point. It's not that Okinawa has so very many cases yet, but it's increasing far too rapidly for the rather limited hospital resources to cope if it continues. And Okinawa is home to some of the oldest people in the world, who would be very vulnerable if they got infected.

An empty shopping mall in Osaka, from last time I visited. We were going back to Osaka again over Golden Week. That idea has been well and truly scuppered.

I save almost 3 hours every day from my commute. We still get up at the same time as before, so now I can go on a long morning run everyday. It feels great!

On the other hand, I no longer have car-time for my podcasts, so I'm running with earphones instead. It would be fine if my earphones — got for free with my phone — didn't kind of suck. I've got a pair of bone-conduction headphones on the way.

Sunset beach in Chatan, last year. This year the whole place is closed.

Surprise: I'm more productive at home.
It's quiet; I have fewer meetings, interruptions and random requests; a standing desk and a nice, big second screen helps a lot.

But also, we've long had access to Microsofts online collaboration tools, including Teams. This situation has forced us to actually start using them, and relying on them for collaboration and information sharing. We're now getting up to speed and they really help improve our workflow a lot

Teams is really surprisingly good. And — major surprise! — they even have an app for Linux. Sure, it's mostly the website wrapped into an Electron app, but everything works fine, including phone and video calls. Microsoft has a  tendency to have two or three confusingly similar tools for everything; a document describing when to use what would be helpful.

Cafe 21 in Shinsaibashi, Osaka. We're teleworking but we're not allowed to work from just anywhere. It's work from home or not at all, basically; channeling your inner hipster from a neighbourhood cafe is a no-go.

Anyway, we're all getting fairly used to meet over Zoom, talk about issues in Teams channels and chats, track tasks in Planner and so on. There's even a modestly active social channel for the IT department; we'll see how that one evolves.

I'm pretty sure we will continue to use these tools after this is all over. It's a lot more efficient to raise minor issues over chat than through email, and it's very convenient to meet without having to traipse across half the campus.

I drink coffee without my co-workers. But I do drink much better coffee, now that I have access to our own kitchen with a proper grinder, beans and so on. 

I'm productive, but I'm also bored. I do miss meeting other people at work, walking around campus, running in the beautiful hilly area over lunch and having coffee breaks with a view.

Two kinds of home-made gyoza, with fried goya and shiso leaves. 

On the other hand, I have time to cook! I'm made most of our dinners and half of the lunches over the past three weeks and I've enjoyed every second of it. As we stay at home and cook by ourselves we're eating way healthier than we used to. I've lost a bit of weight and I feel a lot better overall.

As a side effect we're spending a lot less money. The car sits idle most days, and we're not eating out, going to cafes or anything like that. Good for us; a disaster for the economy. So we do try to spend a bit of that money, on takeout, coffee beans and so on from shops we like.

It's never not time to bake cinnamon rolls! And now I have enough time in the evenings to do so whenever I like.

Restrictions are voluntary,
but people and businesses mostly do understand the situation and at least sort-of follow the recommendations. Except Pachinko parlors. The Osaka mayor tried to shame them into closing by naming them, but a few still stay open, with a flood of gamblers looking for a place to play. If you ever needed proof gambling is an addiction here you go.

Oh, and the Japanese Olympic committee president, Yoshiro Mori, has stated that there will not be a second delay of the Olympic games due to the pandemic, because "The prime minister has determined that one year is sufficient."  I'm happy somebody is keeping their crystal ball well polished...

The fishing pier in Suma, in western Kobe. It was damaged in a typhoon two years ago, and never re-opened. It would be a shame if they let it rot; it's a fun place to visit even if you're not into fishing. For now it's a nice illustration of loneliness.

More Corona

It's been a month and more, and here on Okinawa we're still doing well. Japan was one of the earliest countries to get infected, but until recently they've managed to curtail the spread. We've mostly had isolated clusters of outbreaks around the country, but no real uncontrolled spreading. The reason has been a lot of voluntary closures of events, people taking "social distancing" measures, and testing of people around confirmed patients.

People are still pretty chill about this on Okinawa. Nobody is panic-buying toilet-paper for instance, so there's plenty to go around for everybody. More and more residents are using masks now - it used to be only tourists - but most seem to wear it just to make other people feel safer.

Here on Okinawa we had three cases right at the start, all connected to a visiting cruise ship. We didn't have a single case for over a month after that. Two weeks ago we started getting new cases; it gradually rose to 12, with all but two infected abroad or on the mainland. There has been little spread on the island, but just today another six cases appeared, three with unknown source. So now we have it spreading on the main island as well.

The local economy is fairly dependent on tourism and the loss of travellers has hit that sector very hard. Many hotels have special deals for Okinawa residents, so a couple of weeks ago we spent a weekend in Yomitan near Cape Maeda. We supported local business and got a relaxing weekend getaway.

Japan in general has been lucky so far — Japan at large has been doing something right, or our hospitals would be overrun with patients by now. But now the infection rate is increasing rapidly in Tokyo and Osaka. The political response has been anemic; there's a sense that the government has been slow to react, and more interested in protecting its own image and the economy than trying to keep on top of the disease.

The weather was sunny and warm. We took a walk along the beach, and the sea was warm enough to swim in already. Here a washed-up coconut on the beach that's become shelter for a group of hermit crabs.

They announced yesterday that every household will be given two cloth face masks. This sounds ridiculous on its face (sorry); cloth masks don't really help much at all, and the whole thing sounds like an pointless empty gesture. However, more than a few people think this is the precursor to declaring a state of emergency with self-quarantines, and the cloth masks would be a key element of that.

A Common Rose Swallowtail butterfly.

The Japanese central government doesn't have much constitutional power (they have bad historical experience with powerful governments) so, for instance, they simply can't force people to stay at home or businesses to close. Even a state of emergency enacts only limited powers, and mostly to the prefectures, not to the central government.

But they could require people to wear a mask when entering public areas. As every household has two of them, nobody would have an excuse not to wear one. And as a household only has two, that would directly limit the number of people that could be out and about at any one time. Even though you could substitute another mask, it would establish a general pattern of not going out unless you have a valid, specific reason to do so. Don't underestimate the psychological effect.

If they combine it with semi-voluntary closures of non-essential businesses, this will effectively create a similar lock-down state as we see in other countries without having the legal resources to enforce it directly.

Fishing harbour in Maeda. This sure beats winter in Osaka.

Okinawa still has only a few cases, so I would not be surprised if the local government greatly restricts travel to the islands if or when the state of emergency is declared. As all cases so far have been around Naha and one of the US bases, I would also not be surprised if travel between the islands is suspended or curtailed as well.

My workplace OIST is still operating, but with heavy restrictions. People are increasingly working from home, or are preparing to do so. If you have any cold symptoms at all you need to stay home for 14 days. Most in-person meetings and teaching has been suspended, no visitors are allowed on campus, and we are discouraged from gathering in groups. We are not allowed to travel for any but the most dire reason, and if you do you must self-quarantine for two weeks.

And as of this week, if we meet with anybody travelling from the mainland we need to self-quarantine at home for two weeks. This impacts me directly, as Ritsuko has been in Osaka for the past week or so (for good reasons) and will return tomorrow. I will need to work from home for the next two weeks.

Going outside and getting exercise is usually allowed, and always a good idea. Do it alone and stay outside, and you'll be safe. This is from my usual lunchtime run around OIST.

We have been preparing for this of course; I can do all my current work online, and some colleagues already work from home part time. Working from home for a few weeks won't impact my job directly. Hopefully OIST will still be open in two weeks time.

"There's a swallows nest; please watch your head". Life goes on.

It's Ritsuko's birthday, and this year we were going to celebrate with a concert and birthday dinner in Osaka this weekend.

Except the recent corona virus outbreak decided otherwise; the concert — like most public events in Japan — has been postponed or cancelled to avoid the possibility of spreading the infection. Tokyo Marathon already cancelled the general event for most participants (only the 200-something professionals will run) and there's talk about the possibility that the Tokyo Olympics might have to be cancelled or be held without spectators as well.

Nakanoshima at night. I haven't had a chance to upload (or take) pictures so far this time, so all pictures are from around New Year.

And today the government announced the closure of all primary and secondary schools at least until the new school year starts in April. They lose "only" two weeks, but that includes final exams for some schools and graduation ceremonies; and working parents are caught in a bind having to find day care in a hurry. Preschools and kindergartens are not yet closed but it seems more than likely if the number of cases continue to rise.

With only 171 domestic cases so far, and concentrated in only a few prefectures, more than a few people feel the measures seem a little premature, arbitrary and poorly planned. The conspiracy-minded might notice how a number of simmering government scandals have been pushed off the public consciousness; more likely it's about trying to get ahead of the developing situation. It's better to be criticized for overreacting if it comes to nothing, than for not having done enough if it does blow up.

Utsubo park, almost deserted. Except that this picture was taken around New Year — before the corona virus became more than a curiosity in Japan — fairly early in the morning, and there were plenty of people around if you just chose a different angle for the shot.

Concert or not, we arrived in Osaka earlier today and we intend to enjoy our extended big-city weekend. It's not as if we're in any greater risk of getting sick here than on Okinawa anyhow — Okinawa has three cases so far, while Osaka has one (all connected to tourism). With about 1.4 million people on Okinawa and almost 9 million in Osaka the risk is very low either way.

We do take common-sense measures such as washing our hands frequently (a great way to avoid all kinds of diseases), and avoiding hospitals (another great way to avoid infections).

We don't wear masks. Those paper masks can help prevent spreading it to others if you're already infected and coughing or sneezing, but they do absolutely nothing to prevent you from getting it. Even if they didn't leave big gaps, the paper is much too porous to stop bacteria, never mind a virus like this. It's like using a soccer net to prevent mosquito bites. What they can do is stop big droplets of liquid from spreading when you cough.

To put it this way: I work at a research university, where microbiology and genetics is the largest field of research. We have hundreds of people there who work professionally with bacteria or viruses on a day-to-day basis. Many of them have kids in the day-care center. And not a single one of them wear a paper mask at work. They know just how pointless it is.

What are those masks good for then? My exhaustive research (20 minutes searching the web) says they're mostly used for hygienic reasons, not to stop disease. If you're a dentist or a surgeon, you don't want to drop saliva, nasal mucus, skin flakes or stray hair onto your patient. Same thing when you work with food preparation or any other job where good hygiene is important.

We still have plenty to do here in Osaka. We have dinner reservations on Saturday, we already visited of our favorite places in Kobe on our way here, and I have some errands of my own to run. Ritsuko didn't get the birthday concert she expected, but my brother and his family sent her an impromptu song number instead :-) She loved it.

Valentine's Day

The tradition for Valentine's day in Japan is that women gift men; then the men reciprocate a month later on "White day". That's twice the business opportunity for retailers I guess.

This year Ritsuko decided we're eating more than enough chocolate already (she's right). I don't really drink any longer so beer or whisky is out. Instead she got me this:

Three speciality coffees from a local roaster in Naha. Emerald Mountain from Colombia; Ethiopian Alaka — I've been into Ethiopian coffees lately; and Costa Rica Honey.

Emerald Mountain is a high grade coffee from Colombia and apparently limited to the Japanese market under an exclusivity agreement. Ethiopian coffees tend to be light and fruity or chocolatery with a lot of floral tones; we'll see what this one is like. Costa Rica "Honey" apparently refers to a processing method where the beans are dried with the fruit only partially removed. This will be interesting to try!

All three come from Churamame coffee in Naha. It's a good, very reasonably priced coffee roaster and shop; we often buy our coffee there.

Ah, coffee! This is Emerald Mountain (not that you could tell). Light bitterness, with balanced flavour and spicy tones. Very agreeable. I'd say it's a great morning coffee if it didn't cost so much...

It was time to renew my residence card, and to do that I had to visit immigration. In Osaka this would involve getting there before opening time, stand in line, then wait for perhaps hours before they finish your request.

Knowing this I went to Kadena immigration office (it's on my way to work) well before 9 am with the form already filled in. When I get there there's not a single person waiting. The doors open right at 09:00; I'm still alone so I step right up and give them the form, my old card, my passport and a picture.

Kadena town. It's not big - about 12000 people - but it feels neat and homey, even cozy. It's really too bad about the air base. Of course they can't choose their neighbours, and a military air base can't really help but being noisy and potentially dangerous either.

As I sit down and wait a couple of young American women arrive. They apparently want to change from SOFA status (that's what US military and dependents are in Japan) to a tourist visa - I guess their time in Japan was ending and they want to take some time off with sightseeing before returning to the US.

However, they don't speak Japanese, and they are under the mistaken assumption that if you SPEAK ... SLOWLY ... AND ... LOUDLY and drop all grammar this will somehow make them easier to understand. They spent several minutes half-shouting "SOFA ... NO. GO ... SEE ... VISA ... YES." to the increasingly confused immigration officer (who, by the way, likely understood English just fine). I would honestly not have understood what they wanted either if I hadn't overheard their conversation as they were walking in.

Still a fair amount of older buildings around. With the Pacific Ocean just around the corner, it's really a losing battle to try to keep buildings looking fresh. If bits are not falling off your house you're still winning.

I would have followed this exciting drama to its undoubtedly thrilling conclusion, but at exactly 09:09 the clerk calls me up to give me my passport and my new residence card. I was literally out the door in ten minutes, new card in hand. In Osaka I would still be waiting in line outside the office for the number ticket machine (so I could wait to submit my documents).

My opinion of Kadena has really improved a lot after this. Not enough to live there or anything (you have to really like aircraft noise at all hours for that), but still. I know where I'll go when I need to renew my card again in 2027.

This is how great it felt when I walked out, residence card in hand. The great thing with Okinawan weather is that there's such a lot of it. Including frequent rainbows.

A new Breakfast

I like coffee, and so I read r/coffee on Reddit on a regular basis. Last week one user posted that they like to have coffee and cereal in the morning. As in, coffee and cereal together, in the same bowl.

That made me curious. "Self", I said to myself when I read this, "why not try it? How bad could it be?" So this morning we tried it out.

We start with a bowl of cereal.

Add some coffee (low acidity coffee blend, a medium grind pour-over at 1:13 extraction).

Breakfast time!

How will it taste?

It tasted... Not bad at all. Quite good in fact.

When we were kids a long time ago, our grandmother would sometimes make us a treat by shredding a cinnamon roll into a large mug, then mix in coffee, milk and sugar. This is amazingly delicious (and I believe my brother still makes it for himself from time to time).

Mixing coffee and cereal is really the same kind of idea. It's not nearly as sweet, and you don't have the cinnamon and cardamon flavors from the rolls, of course. Instead you retain a lot more flavor from the coffee itself. Ritsuko feels this mix might be better still with an espresso rather than drip coffee; it would give you a stronger coffee flavor. I feel it was quite good already.

If I moved somewhere and was told that this is how we eat breakfast around here, I would have no problem having this every morning. I do feel that it's a waste of coffee — I prefer to enjoy it sans sugar and roasted carbohydrates if I can — but if you don't care then this is not bad. And if you are short on time, you could grab a mug of coffee and cereal on your way out and have a decent breakfast on the way to work.

Coffee and cereal does work well together. Live and learn.

Osaka and Misasa

Ahh, another new year! It didn't start great — I came back to Naha Monday and I've already burned our tea kettle, and some of our cheese got moldy over the holiday (not a disaster: cut away the visible mold, wash with salt water, wrap it and return to the fridge). Oh well.

Osaka is as subtle and refined as always. Never change.

New year in Osaka is the same as always. New Years eve was at Henrietta as usual (and fun, as usual, even though I didn't drink). Early in the new year I scored a couple of Lucky Bags at the Mizuno flagship store in Osaka — a pair of last years' Wave Rider shoes, insulated shell running jacket and pants, winter shirt, long-sleeve t-shirt, gloves, socks and a towel. All you need for winter running, for the price of a regular pair of running shoes. Not bad.

I guess a steering wheel will work as well. It doesn't strike me as that practical, but the bike did look very good. That was of course the point.

We spent most of New Year in Osaka, but we did go to Misasa in Tottori for one night before New Year. Tottori, for those that don't know (I didn't), is on the Japan Sea side, north of Himeji and Okayama. If the Pacific Ocean side — with Tokyo, Osaka and so on — is the front side of Japan, the Japan Sea side is Japans backside, with fewer people, many rural (and depopulating) areas and few or no large cities.


Tottori is out of the way from the Tokyo-Kyoto-Osaka area so it's not inundated with Asian tourists shouting and shoving people with their tax-free drug-store bags. Misasa is famous for its mineral-rich hot springs, including a few that contain radium — hard to believe, but at one time radiation was considered healthy (and to be fair, small amounts do seem to have some health benefits along with the increased danger).

Getting there is easy: there's a direct train from Osaka station all the way up to Kurayoshi. It takes about three hours. From Kurayoshi it's another 25 minutes to Misasa; the ryokan picked us up with their shuttle bus.

Misasa itself is a smallish village along a river valley. The main business is ryokan and hot springs, although Okayama university have a "institute for planetary materials" (geology department it seems) there as well. Makes sense to have it at a plane with so much geological activity I guess.

Izanro Iwasaki in Misasa. You can get a very nice run just by following the river, crossing it, then running back up to the village. Go far enough and you can return through the car tunnel instead if you like.

We stayed at Izanro Iwasaki. We chose it — and, really, Misasa — because Ritsuko stayed there with her family as a five-year old (not so) many years ago. The main building and the hot springs have of course been extended and renovated, and the garden layout has changed. But a few things, such as the stone lanterns, still remain from that visit.

Traditional kaiseki dinner. It really was very good.

What do you do at a ryokan? Relax. Get out of your clothes and into a yukata. Soak in the onsen, go for a walk, have dinner, watch the river. Let life quietly flow past for a day.

Japanese do like their crab.

I really like onsen (Ritsuko is more about the food). This one was split up into multiple baths indoors and out, and the two gender-separated sides were quite different. The male and female side is swapped every day (every morning at 5am) so you get to experience all the baths. More fun than places that simply duplicate the same bath design.

They have one steam room with radium water. The signs told you not to stay too long; good advice, and I skipped it altogether. My absolute favourite bath was one of the outdoor rock pools. You sat sheltered from the wind with a partial bamboo roof that let through the cold rain falling from above. The feeling of the hot spring heating your body and the cold rain cooling your face as you sat looking up into the sky was wonderful. It must be spectacular when it snows.

I went running of course. The evening run the first day was fine. It was raining when I went out for a pre-dawn run along the river the next morning. When I came back I was cold and soaking wet from the rain. It felt great to wash up and soak in the onsen for an hour before going to breakfast.

We spent some hours in Kurayoshi before returning to Osaka. Protip: always go to a local supermarket when you travel if you can. They will have local stuff — foods, sweets and ingredients — that you can't find at home, and at regular prices. Also, it's a slice of life, and always fun to see. Cafe Source Mid next to the station was a good place for lunch and hang out with a cup of coffee.

This was fun, and we should probably try to do this again next year.
