The Jupyter Notebook is an open-source web application that allows you to create and share documents that contain live code, equations, visualizations and narrative text. Uses include: data cleaning and transformation, numerical simulation, statistical modeling, data visualization, machine learning, and much more.
Voila serves live Jupyter notebook including Jupyter interactive widgets.
Unlike the usual HTML-converted notebooks, each user connecting to the Voila tornado application gets a dedicated Jupyter kernel which can execute the callbacks to changes in Jupyter interactive widgets.
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?!
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:
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 :-).
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: 区. 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, dō (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, 区). (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.
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:
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:

Hate reaching for the mouse? multi-cursor-plus allows you to create multiple cursors anywhere in the buffer, using only your keyboard. Supports multiple selections and removing previous cursors at any time. Easy to use. Amazing!
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.

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…
As the replacement drive for yesterdays hard drive crash was put into place the storage array started to re-silver the newly added empty drive. This process takes a while – about 8 hours for this particular type of array.
Interestingly just 2 minutes into the process another drive dropped a bombshell:
Apparently disk 8 holds together it’s business so far but dropped a couple of parity errors into the equation.
This is bad news. But so far science still is on my side of things and no data has been lost.
But now redundancy is down completely. There’s no redundancy for now – until the replaced hard disk is fully integrated. My policy for these sized drives demands a minimum of 2-disk redundancy and for today this policy saved the day (data).
Actually let’s dive a bit into what it’s doing there to achieve 2-disk redundancy:
Synology Hybrid RAID (SHR) is an automated RAID management system from Synology, designed to make storage volume deployment quick and easy. If you don’t know much about RAID, SHR is recommended to set up the storage volume on your Synology NAS.
You will learn different types of SHR and their advantages/disadvantages over classic single disk/RAID setups. In the end, you will be able to choose a type of RAID or SHR for the best interest of your storage volume. This article assumes that as the admin of your Synology NAS, you are also an experienced network administrator with a firm grasp of RAID management.
After the sudden death of a hard drive in one of the house’ storage arrays (after 55997 hours of service) beginning of this month it has happened again:
With less than half the runtime of the previously dead disk this one is an early failure. Well within the warranty. Therefore the disk is already en route to be replaced by an RMA (Western Digital RMA process so far is spotless!)
Anyhow: This was a 4 TB drive. It’s in an array with 2-disk redundancy and 8 other drives. So the array still is operating with redundancy right now. Additionally a full backup exists as well as a hot-standby (but slower) offsite mirror.
I am quite confident to not loose data. But this raid-sync is going to take a bit longer. As drives get bigger, syncs get longer.
