The nearly 400 year legacy of a cutting edge ceramic coffee filter

This NY Times piece on a 1,020 year old shop in Kyoto has been making the rounds online. It got me thinking about other examples of products or skills that have traversed centuries, and a random discovery we made at a shopping stall: a paperless ceramic coffee filter.

Map showing route from Iki to Arita

Last October we travelled to Imari and Arita, in the prefecture of Saga on the Kyushu mainland. This region of Japan is famous for its porcelain. In the 17th century, as the Ming dynasty collapsed, Chinese porcelain became a rare commodity. Around the same time a kaolinite mine was discovered in this region of Japan. The lords of the region, the Nabeshima Clan, had participated in the invasion of Korea in the late 16th century. Many Koreans were “brought over” to Japan, and the Nabeshimas found some who had the skills to make high quality ceramics competitive with mainland Asia. The Nabeshima Clan hid the potters up in a secluded valley in Arita to “protect the intellectual property” of this new money-maker, shipping finished product downriver to the port at Imari where they could be loaded onto bigger ships bound for Nagasaki and then on to the palaces of Europe.

  • Ceramic shrine dedicated to potters in 1658

This legacy of ceramic-work was put to use in a new way a couple of centuries later. In the late 1800s, when Japan started its process of modernization, the British came to advise on all sorts of things. They helped the Japanese engineer bridges, railways, and other infrastructure, and are the reason why cars are driven on the left in Japan. The British were also responsible for Japan’s new communication network, stringing telegraph cables throughout the country. At the time, the Brits used insulators made of glass. When it came time to replace these with newer and better ceramic insulators, the potters of Arita were called upon for their expertise.

While in Imari and Arita we visited the Kyushu Ceramic Museum and wandered the pottery stores looking at some amazing pieces of art. We even tried our hand at making some vases and painting some mugs. Getting your hands dirty trying to do pottery sure gives you a healthy respect for what the pros can accomplish!

Ceramic technology is of course being still used in all sorts of high tech materials applications like rocket nozzles and 3D printing. I am not sure if that is going on in Arita, but what we did discover are these cool molded ceramic coffee filters that use micro-perforations to allow the water to pass through. We bought this filter and have been using it every day for the past two months. It works a lot better than metal filters — there is very little coffee grit at the bottom of my mug when it is done — and it is more eco friendly. Plus, it looks really cool! Check out the video below. You can see the texture is kind of like volcanic rock, it feels like it is made of sandpaper.

I am sure there are many different examples of traditional skills like this transforming through the ages. If you can think of more examples from Japan or other countries, please add them in the comments!

Writing macrons on macOS and iPadOS

This is a quick tutorial on how to easily type macrons on Apple devices with a hardware keyboard. The onscreen keyboard on the iPad makes this easy, but not when you are using an external hardware keyboard.

This will be particularly relevant to academics needing to write Japanese terms in rōmaji. I searched the web and found all sorts of non-solutions, either out of date or irrelevant, so I am putting this up on the web for others to find. As of 2020, this is the best way.

Hat tip to Hiromu Nagahara on Twitter who told me the answer: set all your input sources to ABC-Extended. This allows you to use Opt+A to insert a macron before you type a vowel.

First, for macOS go to System Preferences → Keyboard → Input Sources, hit the plus button and choose ABC – Extended.

screenshot of the Input sources screen. An arrow indicates where you will see the ABC - Extended listed, and also points out to uncheck the Romaji setting for your Japanese keyboard

This used to be called US Extended, but thankfully they made the name more neutral. It won’t mess up your spellcheck settings, which are actually set in from the Text pane of the Keyboard settings. See below.

Now you can use the Opt+A keyboard shortcut to add a macron:

On your iPad you can do a similar thing. Tap on Settings → General → Keyboard → Hardware Keyboard then your language — mine is English (Canada) — and select ABC – Extended.

Now the Opt+A keyboard shortcut works on your iPad’s hardware keyboard too!

Advocating for the teaching of knowledge to kids

Having been in the Canadian education system for a few years now, I am very impressed with the high-minded ideals of the early education system here. Things like teaching critical thinking, creativitiy, breaking down a problem, LID, etc are challenging and interesting, and meant to get a jump on the future. However it is pretty unsettling how little our kids actually know.

A few weeks ago I tweeted a recommendation for this piece on skills vs knowledge-based curriculum in The Atlantic. This is an extract from The Knowledge Gap, a book by Natalie Wexler that challenges the shift in elementary education away from teaching knowledge (often derisively referred to as “rote learning”) to teaching skills “that will enable [students] to discover knowledge for themselves later on.” Wexler covers some of the history in the article, but I think her argument can be captured in the example she gives about an experiment in reading comprehension using baseball:

… they constructed a miniature baseball field and peopled it with wooden baseball players. Then they brought in 64 seventh and eighth graders who had been tested both for their reading ability and their knowledge of baseball.

[The researchers] chose baseball because they figured lots of kids who weren’t great readers nevertheless knew a fair amount about the game. Each student was asked to first read a description of a fictional baseball inning and then move the wooden figures to reenact it. (For example: “Churniak swings and hits a slow bouncing ball toward the shortstop. Haley comes in, fields it, and throws to first, but too late. Churniak is on first with a single, Johnson stayed on third. The next batter is Whitcomb, the Cougars’ left-fielder.”)

It turned out that prior knowledge of baseball made a huge difference in students’ ability to understand the text—more so than their supposed reading level. The kids who knew little about baseball, including the “good” readers, all did poorly. And all those who knew a lot about baseball, whether they were “good” or “bad” readers, did well. In fact, the “bad” readers who knew a lot about baseball outperformed the “good” readers who didn’t.

There is a lot more in the article (read it!) — but it really hit me coming from an international family. We are always straddling the line between the British Columbian education system and the system “back home.” Furthermore, my day job is related to the US education system and kids’ education is probably the main topic of discussion amongst our immigrant friends, all who bring different perspectives. There is a lot of (amateur) comparative analysis going around, and a lot of confusion. Wexler’s article really captures one of the main challenges in understanding elementary education here when you come from Asia. It also makes me wish there was a way to mash the East with the West.

Now, I bring this article up again after reading an intriguing essay on developing transformative tools for thought. This essay argues for a new ways to leverage technology for efficient memorization techniques. It is adjacent to the “skills vs knowledge” argument from the above article, but hits some of the same notes.

For example, Matuschak and Nielsen present a caricature of a “skills first” proponent:

“Why should I care about memory? I want deeper kinds of understanding! Can’t I just look stuff up on the internet? I want creativity! I want conceptual understanding! I want to know how to solve important problems! Only dull, detail-obsessed grinds focus on rote memory.”

This sounds so much like the “we teach concepts not memorizing facts. The students can look up facts on the internet!” that I have heard from local elementary teachers.

Matuschak and Nielsen then go on to illustrate some challenges experienced in teaching quantum physics:

He noticed that people often think they’re getting stuck on esoteric, complex issues. But, as suggested in the introduction to this essay, often what’s really going on is that they’re having a hard time with basic notation and terminology. It’s difficult to understand quantum mechanics when you’re unclear about every third word or piece of notation. Every sentence is a struggle.

It’s like they’re trying to compose a beautiful sonnet in French, but only know 200 words of French. They’re frustrated and think the trouble is the difficulty of finding a good theme, striking sentiments and images, and so on. But really the issue is that they have only 200 words with which to compose.

So, in order to understand concepts, you need a certain fundamental layer of knowledge. I am not advocating a total swing back to a Confucian-centric pedagogy — there is certainly a balance to be had. We struggle with this as we try to support our kids’ learning from home. It would be ideal if schools took advantage of those little sponge-like young brains in their early years and filled them full of facts before introducing higher-order thinking skills. But in lieu of that, I suppose it is up to us parents to provide them with actual knowledge (eg. in the forms of structured textbooks, encyclopedia, atlases, etc.) to fuel the skill-based curriculum they get at school. We have tried a few things (tutors, workbooks from other education systems, etc) but are always looking to improve. If you have any recommended resources or techniques for supporting your kids, please share!

Nostalgic utopianism — a review of Throwing Rocks at the Google Bus

cover-throwing_rocks_google_bus.jpg

Throwing Rocks at the Google Bus: How Growth Became the Enemy of Prosperity  by Douglas Rushkoff

Power corrupts and money ruins everything. These are basically the premises that Douglas Rushkoff starts from in his latest book, a critique of the concentration of power in the digital economy and the inequality it breeds. He uses the protests targeting private Google buses in 2013 to highlight the inequality driven by the US economy dominated by the monopolous forerunners of the digital economy. I was in SF at the time, and commented on what I saw:

I was struck by how conflicted the city is. The chasm between those in tech and those not in tech is nearly at class-warfare levels. Almost daily there are articles about the chasm widening (eg. the recent Google Bus demonstration). To get better sense of the civic strife, read the following link-filled article: Silicon Valley Is Living Inside A Bubble Of Tone-Deaf Arrogance.

Rushkoff has always been writing on the edges of technology and society. Now he tries his hand at technology and economics. His argument is that the digital economy is not a disruption, but merely an extension of the industrial age, with the problematic bits of that era even more acute. He takes great pains to show the monopolistic tendencies of networks and the ill effects of “digitally accelerated capitalism.” The evidence that he provides is damning, but his framework of analysis is not particularly convincing. His mistake is to analyze corporations using McLuhan’s tetrad of media effects, which ends up looking like this:

  1. What does the corporation enhance?
  2. What does the corporation make obsolete?
  3. What does the corporation retrieve that had been obsolesced earlier?
  4. What does the corporation flip into when pushed to extremes?

It is an interesting thought experiment, but ultimately fails where more traditional economic arguments would succeed. The results are muddled. For example in chapter 21 he criticizes mainstream economic education, yet nowhere in the book does he name alternative economic models. The terms “neoliberalism”, “socialism”, “socialist democracy” never appear in the book. “Communism” pops up a handful of times, but only in a defensive matter:

For a business to find its appropriate size even if this means scaling down is not a Communist Plot. [pp. 105]

Rushkoff fears being accused as “communist” above all else, and that ends up undermining his argument. For Rushkoff, there is only Capitalism and Communism. His understanding of political theory comes off as unsubtle, but maybe it is the the limited of understanding of his audience that is influencing him, aka. the big tech CEOs that ask him for advice running their companies or hire him for highly paid corporate speaking engagements. This economic calculus might be the reason for Rushkoff’s lukewarm critique. He is not willing to go to the radical, or use radical language for fear of alienating his audience (née customers). The result is a fuzzy, friendly, plush toy critical theory. He is good at pointing out how damaging capitalism is, but instead of rejecting it, he dreams of a more “conscious” capitalism, a more “humane” capitalism. His solution is go back to a pre-industrial economic model, like the putting out system. Imagine a massive distributed network of makers 3D printing bespoke items for their neighbours out of their handmade cottages. This is how it should have been. Rushkoff is a nostalgic utopian, and this is further evidenced by his analysis of the internet.

Many of the greatest hits of 1990s internet theory are covered in this book, each critiqued and shown how they were not bourne out in the past decade and a half. Rushkoff gives a recent history lesson, showing how terrible things currently are, but then wishes things were like the old theorists thought it would be. Rushkoff is an early model cyberutopian.

However, there is a difference: the saviour of our society is not necessarily technology(!). In fact, Rushkoff argues that it comes down to how we structure our firms and our economy that will save society (aka. politics). That being said, he still thinks that distributed technologies can play a big role in achieving a less centralized system. Thus, Rushkoff’s view might be categorized alongside Steven Johnson’s peer progressivism (see some of my old thinking about PP here).

Throwing Rocks at the Google Bus might not be the final wrench in the gears of our system of unfettered cyber-capitalism, but it is still worth the read. There are some excellent arguments in here against our addiction to growth, some cool examples of alternative transaction systems (local currencies, time dollars, LETS), and a spectacular takedown of startups and venture capital near the end of the book. Despite coming up short in its overall analysis, it is a good book to recommend to a friend who has just started to smell something bad in tech, knows something wrong, but is not quite ready for a full-blown attack on the real underlying problem: capitalism itself.

More people than bots?

In 1975, BusinessWeek magazine imagined the rise of the paperless office as computer use became more widespread. Of course, over the following two decades, consumption of paper doubled. A couple more decades on, we are finally seeing year-on-year decreases in office paper use, at least in North America and Europe.

One recent tech fascination is bots. Retailers are especially interested in bots which will allow consumers to ask unstructured questions about products and help them order pizza or whatever. Bots may be the latest advance in customer service automation, but, they aren’t quite up to scratch. There are still plenty of limits to overcome with machine-learning and natural language processing. It will not likely take four decades like the paperless office, but automated sales bots are still a ways off. In the meantime, what is likely to happen? To put it another way, how will the “paper double”?

Why NOT Uber?

What do people really want when they say they want Uber to come to their community?

Once they learn about all the scandals, lawsuits, riots and demonstrations, the many lists of reasons not to use Uber, most people come away with a nuanced opinion. But typically, at first blush, many people have a very positive reaction to Uber. Why?

One reason could be the marketing. Uber is a poster child for the “sharing economy” — a feel-good marketing term that is inaccurate and “needs to die.” In his excellent book What’s Yours is Mine: Against the Sharing Economy author Tom Slee digs into the hopes and promises of the new rash of sharing economy companies, and shows how they fail to deliver and can actually damage our society.

A key objective of marketing is generating demand. Recently in Kelowna Uber Canada held two information sessions to “gauge interest”. Uber is really good at this. They turn their users into lobbyists, use social media effectively (see the recent province-wide #bc4uber hashtag campaign), and they get local governments to lobby on their behalf. As of last summer they had 250 lobbyists and 29 lobbying firms registered in capitols around the US. Earlier this year our provincial political leaders jumped on the bandwagon and spent money on their own ad campaign for the sharing economy.

Uber is able to get many people on its side through marketing, but that cannot be the only reason people like (at least the idea) of Uber. There seems to be some deep-seated dissatisfaction with the state of transportation as it is today.1 Let us examine some of these arguments.

Often Uber proponents say 1) taxis are expensive and there is no competition; 2) that they can never get a taxi when they need one; and 3) the Uber experience is better.

Sectioned — On tech coverage in local media

Our mayor ran on a platform including tech.

Our premier seems to have shifted her economic policy to tech.

Our downtown is physically changing thanks to tech.

Dozens of new tech companies start here each year. Dozens die, too.

We are told it is a $1 billion industry. (Tourism is $840M by comparison.)

There is a lot of activity, a lot of money, and a lot of influence involved.

ao_infographic.jpg
We have 321 tech companies here.

The above points indicate that local media in Kelowna should consider adding a dedicated tech section to their coverage. Currently, only KelownaNow has a tech section under Lifestyle, and a few months ago Kelowna Capital News ran a “Tech Talk” package.

Kelowna is starting to be considered a “tech” hub and the public deserves well-rounded, informative pieces which examine how technology impacts the local community. I am not talking about a “gadget review” section — that is better left to larger publications. What is more important to locals is investigating and explaining the social, political, and economic impacts of the local technology sector. Here are some examples of what I would like to see:

Nice coverage of tech issues at the local level

Kelowna Capital News Tech Talk special

Kudos to Kelowna Capital News, one of our local newspapers, for running a special on technology last week. Tech is one of the dominant problems in the global zeitgeist, and it is not often that a local paper will put the resources into exploring such an issue in a local context. The Tech Talk package dubbed “Mainframe Communication” (!) is not super hard-hitting, which is understandable since it is geared toward a more general audience, but despite it’s name I think it shows an extraordinary level of awareness. I look forward to more coverage like this.

Included are articles on education, local politics, and employment with some pieces on the legal and social ramifications of unfettered tech. To read it online, check out this piece on Kelowna’s tech economy and see links to all the other articles in the package in the footer of that article.

A slim crisis — a review of Disruptive Power

cover of Disruptive Power

Disruptive Power: The Crisis of the State in the Digital Age by Taylor Owen

From the book:

Coupled with the power that is derived by the state’s increasing sophistication in this space — whether through automation, biometrics, or the new forms of social control and the violence they enable — there is reason to question the narrative of empowerment that has been explored throughout this book.

Emphasis added. This quote comes from page 184 (of 210). That is 88% of the way into the book. It reflects my frustration with this book, as I spent much of my time questioning the “narrative of empowerment.”

Owen does a good job giving an overview of the state of tech and the state. Each chapter tackles big issues in tech and the way we govern ourselves: “activists, humanitarians, journalists, … terrorists”. All the usual suspects make an appearance — Anonymous, Bitcoin, Ushahidi — and the tried and true analysts like Shirky, Benkler, and Castells are cited at length.

But there is a shocking lack of critique.

A simple example:

Anyone can now disseminate information on a new media infrastructure. Blogs, social networks, and the wider Internet all allow people to self-publish and have the capacity to reach most people around the globe.

This completely ignores the inherent power imbalances the incumbents have (ie. talent pools, media relationships, existing audiences etc). Joe Sixpack blogger != CNN. This kind of statement has been debunked time and again. Throughout Disruptive Power there are a number of these observations which are seated more in the cyberutopian wishful thinking of the 1990s, than the analyses bourne out in the past few years.

Throughout the book Owen derides hierarchy, lauding liquid democracy and the “flat” structure of Occupy Wall Street. This belies how fractured and terrible the decision-making was/is in OWS and the Pirate Party. Owen pits hierarchy against networked organizations — yet, hierarchy is simply a type of network architecture. The book is riddled with such simplifications, and it detracts from his overall argument.

Owen cites tech critics like Evgeny Morozov, so he is surely aware of the negative aspects of the tech-boosterism he seems engaged in. His Twitter activity is also evidence of this. So why is this book so one-sided? Later in the book Owen takes on a more critical tone, and these chapters are much more satisfying. It is almost like this book was written in the same order it is presented, and the longer he researched, the more nuanced his opinion became.

A more likely hypothesis is length: Disruptive Power is a mere 210 pages (plus endnotes), and gives a whirlwind tour of some very large trends. Books have been written on each of the chapter topics. Owen barely scratches the surface. I would have liked him to add another 120 or so pages and include a more rounded-out argument. Disruptive Power may be a good primer on these topics, but it is not a thorough critical analysis. Read it as the beginning of a journey into this topic, not to get caught up on the current state of affairs.

More than computers — A recap of LinuxFest Northwest 2015

For me, this year’s LinuxFest Northwest 2015 was learning more about the politics of the Free Software movement. This track featured some excellent and eminent speakers, and I enjoyed it very much. Here is a short recap of each session:

1.

Deb Nicholson, the Director of Community Outreach at the Open Invention Network gave an entertaining talk called Patents and Copyright and Trademarks: A Primer for Developers. Using plain language and funny pictures, she delineated trademarks (how it looks), copyright (the content), and patents (how it works) in a simple way. I enjoyed her examples of “trademark collision” and where things get fuzzy with regard to patenting software.

2.

Bradley Kuhn, former director of the Free Software Foundation brought the controversy in his talk Considering the Future of Copyleft: How Will The Next Generation Perceive GPL?. You can see a previous version of the talk on YouTube. Basically he advocated the enforcement of licenses, the abandonment of weak copyleft, and bringing the principles of copyleft to a new generation of coders. Javascript and Android are the new fronts for free software in this age, and the young devs coming up are used to wiring together frameworks and APIs without much knowledge or background about licensing. This is a long-term problem for the free software movement. As I summed up in my tweet from the event:

3.

Every year at LFNW there is an ACLU/EFF Panel Discussion. This year Seth Schoen from the EFF partnered with ACLU Washington state’s Technology and Liberty Director Jared Friend. Seth was great as always, and I was really impressed with Jared. As usual the crowd got pretty riled up. The discussion included stingrays, the terrible DMCA exemptions process, and fighting 215. The EFF must make a chunk in donations on LFNW weekends, but I feel like we in the crowd want to do more, but can’t, and feel helpless.

4.

The final talk I took in was an intro to The Free Software Foundation Licensing & Compliance Lab; We Fight for the User by Donald Robertson who is a Copyright and Licensing Associate with the FSF. This was a more informational session, but I came away with a much better understanding of the FSF and its activities.

Other interactions

With 1800 attendees and a bunch of exhibitors, you can bet you are going to meet some interesting people at LFNW.

Late Saturday, on the way to our traditional drinking spot Uisce, we stopped by The Foundry, Bellingham’s Makerspace. They had a really nice setup with electronics, sewing, woodworking corners in addition to the “traditional” 3D printers, laser cutters and the like. Check out my album on Flickr to see their amazing PAPER 3D printer. This thing blew my mind. (They have better pics on their

(http://www.bellinghamfoundry.com/gallery/)). We capped off the visit by playing a 3D printed guitar and 3D scanning my head. Good times.

On Sunday I wandered the exhibitor’s floor rather than going to sessions.

I spoke with the executive director of Geeks Without Bounds, and we had a good discussion about balancing fervor for technological solutionism and the realities of delivering aid through established frameworks. I am confident that GWOB isn’t simply about air-dropping mobile phones across the developing world and telling them to simply apt-get install democracy.

There was another deep discussion with Aaron Wolf from Snowdrift.coop, which is a platform for coordinating donations to F/OSS projects to make a bigger impact on development (those are my words). Rather than tons of disparate small donations going to disparate projects, getting everyone to put there money in the same place can push a project forward in a meaningful way. The vision of the project, and the idea to convince proprietary projects to go open once a sustainable ecosystem is developed is intriguing and worthy, even if extremely challenging. Check them out.

In conclusion

LFNW is about more than computers. There is a rich background of history and culture to the Free Software movement and the Free Culture movement. Learning about the ways these organizations fight for every user’s rights through legislative, legal and technical means is empowering. It is not all about the tech, but about the politics and social norms that underly every human endeavor. This recap should demonstrate that you do not have to be a Linux geek to enjoy LinuxFest. There are tons of learning and networking opportunities for developers and users of all kinds.

I did not touch a command line all weekend. Which suits me, since I only have a Mac and wouldn’t want to be scorned by all the true neckbeards there. 😉
