Apparently the german main train operator does offer their regional and nationwide train network in an overall one-pager plan version:
Now, if you take the nationwide one, it looks like this:
It looks okay, but not that great. Given the many examples of proper train network plans.
Someone as well was not satisfied, so this person created one and put it on reddit:
This is so much nicer! Of course this has to be taken with the addition of: there are several “jokes” hidden in the names and lines. Don’t take this as an actual reference – rather go by the official ones.
When you are dealing with IoT protocols, especially at hobby-level, you probably came across the MQTT protocol and the challenge to have all those different devices that are supposed to be connected actually get connected – preferably using the MQTT protocol.
Recently this little project came to my attention:
OpenMQTTGateway project goal is to concentrate in one gateway different technologies, decreasing by the way the number of proprietary gateways needed, and hiding the different technologies singularity behind a simple & wide spread communication protocol: MQTT.OpenMQTTGateway
OpenMQTTGateway support very mature technologies like basic 433mhz/315mhz protocols & infrared (IR) so as to make your old dumb devices “smart” and avoid you to throw then away. These devices have also the advantages of having a lower cost compared to Zwave or more sophisticated protocols. OMG support also up to date technologies like Bluetooth Low Energy (BLE) or LORA.
Of course, there is a compatible device list…

I was pointing to BitSavers before. And I will do it again as it’s a never ending source of joy.
Now some old schematics had been spilled into my feeds that show how logic gates had been implemented with transformers only.
And not only BitSaver is on this path of sharing knowledge, also TubeTime is such a nice account to follow and read.
Previously you had to be in Japan or to have a japanese AppStore account to get access to software that allows you to manage and add SUICA cards to your wallet and use it right-away for public transport.
Now with the 2020 olympics approaching more and more tourist support-apps are made available to non-japanese audiences.
Just like this little helper:
So the scenario was: You arrive at an airport in Japan. And the first thing you needed to do to use the public transport system was to get such a SUICA card either purchased or topped-up.
This is a straight forward process and they even came up with “Tourist SUICA” cards that will deactivate themselves after a certain amount of time and are cheaper to purchase upfront – still it was a process you had to know how it works.
With the above helper app you’re simply doing this:
- Download app.
- Make sure you’ve got Apple Pay set-up with at least one of your credit cards
- Use the SuicaEng app to create a brand new SUICA card out of thin air and top it up right there.
- (optional) push your SUICA card to your watch to simplify the purchase processes even more – you’ll just tap your wrist to pass through gates or purchase goods.
When you own a recent iOS device (iOS 11 and up) you’ve got the choice between “High Efficiency” or “Most Compatible” as the format all pictures are being stored by the camera app.
Most Compatible being the JPEG format that is widely used around the internet and other cameras out there and the “High Efficiency” coming from the introduction of a new file format and compression/reduction algorithms.
A pointer to more information about the format:
High Efficiency Image File Format (HEIF), also known as High Efficiency Image Coding (HEIC), is a file format for individual images and image sequences. It was developed by the Moving Picture Experts Group (MPEG) and is defined by MPEG-H Part 12 (ISO/IEC 23008-12). The MPEG group claims that twice as much information can be stored in a HEIF image as in a JPEG image of the same size, resulting in a better quality image. HEIF also supports animation, and is capable of storing more information than an animated GIF at a small fraction of the size.Wikipedia: HEIF
As Apple is aware this new format is not compatible with any existing tool chain to work with pictures from cameras. So you would either need new, upgraded tools (the Apple-way) or you would need to convert your images to the “older” – not-so-efficient JPEG format.
To my surprise it’s not trivial to find a conversion tool. For Linux I’ve already wrote about such a tool here.
For macOS and Windows, look no further. Waltr2 is an app catering your conversion needs with a drag-and-drop interface.
It’s advertised as being free and offline. And it works a treat for me.

It’s 3.8 kg and delivers 25.5 kg of force. Impressive! And it’s in stores (in Japan).
The “Every Muscle Suit” has a lot going for it. Weighing just 3.8 kilograms, the pneumatic artificial muscle suit is powerful enough to generate up to 25.5 kilogram-force and effectively relieves pressure on users’ backs when performing activities like heavy lifting.
Best of all, its streamlined design conceals an advanced air pressure system that doesn’t require electricity or batteries.Japan Today

Please read this first paragraph and let it settle:
At the core of the BrainScaleS wafer-scale hardware system (see Figure 90) is an uncut wafer built from mixed-signal ASICs , named High Input Count Analog Neural Network chips (HICANNs), which provide a highly configurable substrate that physically emulates adaptively spiking neurons and dynamic synapses (Schemmel et al. (2010), Schemmel et al. (2008)).
I’ve highlighted in bold the portion that I want you to think about once more. We are not talking about chips, dies or cut-up wafers.
We are talking about real-size, huge, fully developed wafers filled with logic. For the sole purpose of brain scale neural network research and development…
The Neuromorphic Computing Platform allows neuroscientists and engineers to perform experiments with configurable neuromorphic computing systems. The platform provides two complementary, large-scale neuromorphic systems built in custom hardware at locations in Heidelberg, Germany (the “BrainScaleS” system, also known as the “physical model” or PM system) and Manchester, United Kingdom (the “SpiNNaker” system, also known as the “many core” or MC system). Both systems enable energy-efficient, large-scale neuronal network simulations with simplified spiking neuron models. The BrainScaleS system is based on physical (analogue) emulations of neuron models and offers highly accelerated operation (104 x real time). The SpiNNaker system is based on a digital many-core architecture and provides real-time operation.https://electronicvisions.github.io/hbp-sp9-guidebook/index.html

Shorthand is an abbreviated symbolic writing method that increases speed and brevity of writing as compared to longhand, a more common method of writing a language. The process of writing in shorthand is called stenography, from the Greekstenos (narrow) and graphein (to write). It has also been called brachygraphy, from Greek brachys (short) and tachygraphy, from Greek tachys (swift, speedy), depending on whether compression or speed of writing is the goal.Wikipedia
Of course there’s hardware:

As you might know by now I am re-implementing MyFitnessPal functionality into my own application to be deeper integrated with kitchen hardware and my own personal use-cases rather than to be an add infested subscription based 3rd party applilcation.
So the development of this is ongoing, but I wanted to note down some progress and explanation.
Let’s start with explaining the name: Tabemono.
It does really mean something – and as some might have guessed – in japanese:
Tabemono – 食べ物
Taking just the first Kanji:
Implementing the UI from the UX has proven to be as challenging as expected.
When we started to toss around the idea of re-implementing our food-tracking-needs we started with a simple scribble on post-it notes.
This quickly led to a digital version of this to better reflect what we wanted to happen during the different steps of use…
It wasn’t nice but it did act as an reminder of what we wanted to achieve.
The first thing we learned here was that this will all evolve while we are working on it.
So during a long international flight I’ve spent the better part of 11 hours on getting the above drawing into something resembling an iOS user interface mock-up. With the help of the (free for 1 private project) Adobe XD I clicked along and after 10 hours, this was the video I did of the click-dummy:
Since then I’ve spend maybe 1 more day and started the SwiftUI based implementation of the actual iOS application.
And this brought the first revelation: There are so many ideas that might make sense on paper and in a click-dummy. But only because those are just tools and not reality. It’s absolutely crucial to really DO the things rather than imagine them.
And so the second revelation came: If I had an advise to any product manager or developer out there: Go on and pick a project and try to go full-circle.
You ain’t full stack if you’re missing out on the understanding of the work and skill that your team members have and need.
