Craft Beer in Tokyo (Kanto)

There are lists of things all over the internet. I’ve linked to some of these food related lists and maps already on this blog.

And of course there’s this list of craft beer breweries missing:

microbrewery or craft brewery is a brewery that produces small amounts of beer, typically much smaller than large-scale corporate breweries, and is independently owned. Such breweries are generally characterized by their emphasis on quality, flavor and brewing technique.

Tesla battery survey

If there is any discussion or argument about electric mobility these days the topic of range and battery-aging is coming up rather quick.

Every once in a while you also hear these awesome stories about electric cars achieving total-driven-distances outrageously huge compared to combustion engine cars…

But what is it then, how does a battery in an electric car age over time and mileage? Given that car manufacturers seem to settle on a ca. 150.000km total-driven-miles baseline for giving a battery-capacity percentage guarantee. Something like…

The future owners of ID. models won’t need to worry about the durability of their batteries either, as Volkswagen will guarantee that the batteries will retain at least 70 per cent of their usable capacity even after eight years or 160,000 kilometres.

Volkswagen Newsroom

or

Model S and Model X – 8 years (with the exception of the original 60 kWh battery manufactured before 2015, which is covered for a period of 8 years or 125,000 miles, whichever comes first).

Model 3 – 8 years or 100,000 miles, whichever comes first, with minimum 70% retention of Battery capacity over the warranty period.

Model 3 with Long-Range Battery – 8 years or 120,000 miles, whichever comes first, with minimum 70% retention of Battery capacity over the warranty period.

Tesla

So. Guarantees are one thing. Reality another. There’s an interesting user-driven survey set-up where Tesla owners can hand in their cars data thus participate in the survey.

And it yields results (getting updated as you read…):

In a nutshell: It seems there is a good chance that your Tesla car might have an above 90% original-specified-battery-capacity after the guaranteed 100.000 miles and even after 150.000 miles (241.000km)…

Good news that is! Given that the average household will do about or less than 20.000 km/year it would mean over 12 years of use and the car still would hold 90% of battery charge. The battery being the most expensive single component on an electric car this is extremely good news as it’s unlikely that the battery will be the reason for the car to be scraped after this mileage.

seen: properly scrolling through code

When working on source files with wide-ranging scopes, I wish source editors could pin the declaration lines to the top of the window like section headers, something like this…

Joe Groff on Twitter

This looks like something that would really make a difference when editing code. Let’s see how long until we get something like that in modern editors…

I/O Is Faster Than the CPU

I/O is getting faster in servers that have fast programmable NICs and non-volatile main memory operating close to the speed of DRAM, but single-threaded CPU speeds have stagnated. Applications cannot take advantage of modern hardware capabilities when using interfaces built around abstractions that assume I/O to be slow. We therefore propose a structure for an OS called parakernel, which eliminates most OS abstractions and provides interfaces for applications to leverage the full potential of the underlying hardware. The parakernel facilitates application-level parallelism by securely partitioning the resources and multiplexing only those resources that are not partitioned.

Tilt your head, be more aggressive

“We show that tilting one’s head downward systematically changes the way the face is perceived, such that a neutral face—a face with no muscle movement or facial expression—appears to be more dominant when the head is tilted down,” explain researchers Zachary Witkower and Jessica Tracy of the University of British Columbia.

Celebrate Imaginary Friend Day

Recognize and credit your imaginary friend, whom you blame for everything on all the other days of the year. Or help someone anonymously, but in a way they’d never expect. (“Captain Tuttle” was the made-up buddy of Benjamin Franklin “Hawkeye” Pierce and “Trapper John” McIntire on the TV show M*A*S*H. They used the mythical captain’s identity to get supplies and funds from the U. S. Military which were then sent to help an orphanage).

Japan wants 5G

TOKYO — Japan’s government will allow NTT Docomo and its three major mobile rivals to set up 5G base stations on traffic signals, hoping to reduce the cost and time it takes to roll out the ultrafast networks by taking advantage of the nation’s high density of traffic lights.

Nikkei

Interesting. It seems that there is another way of doing things when you want to see success. Japan always seems very determined when the decision has been made to adopt something. In the curious case of the mobile communication standard 5G they have chosen a different way over countries like Germany.

Last year when I had asked for a new mobile plan here in Germany and I expressed my surprise about the enormous prices for just data quota I was told “That’s because we had to bid on the frequencies and that was soooo expensive that now we cannot offer the service cheaper”.

“are you still watching?” – tailfix

drop in replacement for tail -F that asks you if you are still watching

Just like Laura I am also was having a moment when I stumbled across tailflix.

For those not understanding the reference: At the end of an episode you’ve watched on Netflix you will be shown another one, and so on, and so on. Until if you have not touched the remote at all for several episodes Netflix will ask you “Are you still watching?”.

how long until …

I am a happy user of the Apple Watch and iPhones in general. It’s working out great for me so far.

There are a couple of features that I would wish where there. And simple things like an hour-chime or hour/half-hour tap are frequently included into the WatchOS updates.

But some of the more specific features just won’t materialize on Apple Watch.

Think of this: You are doing your thing, you know, being a productive member of the society. And apart from the information “What’s next” the information of “When’s next and how long until then” is equally important.

I already had all information – like upcoming events – in my calendar. Why not have the watch display directly on the watch face how long I’ve got until then?!

This is where I’ve found an app called “Time Till” by Rachel Higley.

You’re downloading it on your iPhone and when opened up first it will show you a list of your calendars.

You can turn on/off any of them in this app and by doing so you are selecting which of the calendars will be included in the calculation “how long until the next meeting”.

I’ve only selected one calendar which holds those appointments that I need to know how long until then. So it’s not the next work meeting. It’s important things.

On the watch, however many calendars you’ve selected, it will show you something like this:

I’ve circled the complications added by “Time Till”

So in this case it’ll show the hours until I have to wake-up. Whatever I put into this calendar will show up there. If I want with the name of the event, but most commonly I am using the bottom right version: just the hours/minutes until.

Unfortunately Rachel is quite busy and so there’s no update for the app to also support the new Modular Infograph complications of WatchOS 5 and up.

If you don’t know how those look like, here is a picture I’ve put together from Apples developer documentation:

So I am thinking to rewrite the app and include the new complications. In fact: I’ve implemented my “Discordian Calendar Apple Watch Complication” app as a test and exercise to learn how I would be able to rewrite “Time Till”.

Now the only thing I need is to be kissed by the muse that fuels the urge to just get it done :-).

when 川崎市 got the 区

Addresses in Japan are fascinating. There’s a system to it, with lots of exceptions and special cases. And just recently there was an announcement about the city I am technically considering home-base when in Japan: Kawasaki (川崎).

As you see in the title of this post there’s a kanji character missing:

川崎 means “Kawasaki” – just the name itself, like used on signs and such.

川崎市 means “Kawasaki-shi” – the name got extended by -shi which in itself will signal that the name before is a city.

And then there is this other kanji in the title: . It is spoken as “ku” and basically means “ward”. It’s a bigger city broken down into separate wards.

Not all cities in Japan are required to differentiate into wards – just the ones considered big enough. Kawasaki was considered big enough by 1972 to name out it’s wards.

And so its the Nakahara-ward (中原区) I am usually staying to be more specific on the Kawasaki-home-base-statement at the beginning of this post.

And the designated cities are somehow ranked according to their population. The news here is that apparently given the 2019 population numbers Kawasaki has improved it’s position among all big designated cities by one rank:

Some more details then to the japanese addressing system:

Japanese addresses begin with the largest division of the country, the prefecture. Most of these are called ken (県), but there are also three other special prefecture designations: to (都) for Tokyo (道) for Hokkaidō and fu (府) for the two urban prefectures of Osaka and Kyoto.

Following the prefecture is the municipality. For a large municipality this is the city (shi, 市). Cities with a large enough population, called designated cities, can be further broken down into wards (ku, ). (In the prefecture of Tokyo, the designation special ward or tokubetsu-ku, 特別区, is also used for municipalities within the former city of Tokyo.) For smaller municipalities, the address includes the district (gun, 郡) followed by the town (chō or machi, 町) or village(mura or son, 村). In Japan, a city is separate from districts, which contain towns and villages.

Japanese addressing system

So let’s make an example, since it’s always great fun for me to figure out the address again when I try to order the SIM card to the hotel address. A good example would be a randomly selected and nice hotel in Nakahara-ku:

Richmond Premier Hotel address as written on it’s website.

The typical english-language online order form / address entry form for shipping SIM cards to hotels gives you this interface:

Ha! Now that’s a challenge, right? At first glance its not obvious but if you take a look at the structure of the address it opens up:

And so, this will reach it’s destination:

絵描きさんの作業環境が見たい – I want to see artists’ work environments

We are using computers every day and we are doing this in many different environments. Some of us give their desk space and work environment some more thoughts.

If you want some inspiration regarding your desk and work space, take a look at this great Twitter Hashtag: #絵描きさんの作業環境が見たい

It means “I want to see artists’ work environments” and is used for some years now for japanese artists to post pictures of their work environments…

I also had posted mine, yet not being an artist.

N8.5 – Tokyu White

It always seems to me so much easier to meet a Hackers in Japan than anywhere else. Maybe social-gravity works different there. Or there are more of them.

Whatever the reason, I keep crossing paths with people that more or less deep-dive into topics and understand systems in ways and in details that you would normally not expect.

And todays example is a detail you would normally not think about:

The footbridge that was newly built in Shibuya was painted in N8.5. This is commonly known as “Tokyu White”…

“Tokyu White”, N8.5, … of course…if you would need a bucket of this you can order it online.

how did games get to 82 Gbyte sizes?

Every month there are free games to download and try out with the Playstation Plus subscription. There was a game named “Conan Exiles” included and so my Playstation started the download.

After the download taking unexpectedly long I checked the download queue and found the reason why it would take so long to download. This game is over 82 Gbyte in size. This is quite unexpected.

Conan Exiles is an open-world survival game set in the brutal lands of Conan the Barbarian. Survive in a savage world, build your kingdom, and dominate your enemies in brutal combat and epic warfare.

Start with nothing but your bare hands and forge the legacy of your clan, building anything a small home to gigantic fortresses and entire cities. Wage war using swords, bows, siege weapons, and even take control of giant avatars of the gods and lay waste to enemy cities.

Explore a vast, seamless world full of challenge and opportunity. Hunt animals for resources, slay monsters for treasure, and delve deep underground to discover the secrets of ancient civilizations.

Conan Exiles: The Game

It’s still downloading. But what content could await if it only fits into 82 Gbyte of (assuming) compressed data?!

more small projectors coming

Good news everyone!

There are new micro-projectors coming and they are looking good. After the first availability of really small and low-power but enough-light LED projectors (see here) manufacturers have apparently added a laser to the equation.

It is said that…

Unlike traditional projectors that constantly need to be focussed, the Nebra AnyBeam picture is always perfect. You can project onto curved or irregular surfaces with ease – perfect if you want to use it on the fly, or if you want to try your hand at a bit of projection mapping!

This thing will be available, according to the Kickstarter, as a all-in-one package with power and HDMI inputs. It’s got 720p inputs. Well. Well really?

And it will be available to the maker market as a RaspberryPi Hat…

Meeting with a hologram

I can never wrap my head around how people really only use audio to communicate within teams, across cultures and timezones.

I’ve experienced first hand what a difference it makes to use good video conferencing that actually works. And it makes such a difference on productivity and team collaboration.

Video conferencing never replaces real-life face-2-face meetings. It just does not start relationships.

If you already had your work and personal relationship started video conferencing will make all the difference to your work.

Anyhow: I am also a big believer in augmented-reality glasses. I have to wear glasses anyhow all the time – why not improving them with the ability to display stuff.

Now, think of this. You’ve got one of those AR glasses on and you start the video conference call. And this happens:

Please. Give. It. To. Me. Now.
