Erlebnis Museum für Nachhaltigkeit, Innovation und Wissenschaft

3 min read

Mein Vorschlag ist, ein neues, spannendes Wahrzeichen für Düsseldorf zu bauen, das sowohl ein kulturelles Zentrum für die Bürger als auch ein touristischer Anziehungspunkt sein kann: ein Museum für Nachhaltigkeit, Innovation und Wissenschaft. Dieses würde die Größe und die zentrale Lage des Geländes voll ausnutzen.

Dieses Museum könnte ein neu konzipiertes Wissenschaftszentrum sein, das sich auf Innovationen und nachhaltige Lösungen für die Zukunft konzentriert. Es könnte Kindern, Jugendlichen und Erwachsenen interaktive, immersive Erlebnisse bieten, zukunftsweisende Ausstellungen zeigen, lokale umweltfreundliche Unternehmen vorstellen, Bildungsmöglichkeiten für Schulen anbieten und Räume für den Ideenaustausch mit Technologieschulen, Vereinen und Universitäten bereitstellen.

Als Elternteil, der in Düsseldorf lebt, weiß ich, dass ein solches Museum die Stadt familienfreundlicher machen würde. Derzeit gibt es nichts Vergleichbares: nur den Aquazoo, der etwas veraltet scheint, nicht sehr interaktiv ist, nicht zentral gelegen ist und am Wochenende immer zu voll ist (natürlich vor der Pandemie). Ich denke, das würde auch helfen, die Stadt für Touristen attraktiver zu machen, besonders an Sonntagen, wenn nicht viel los ist.

Museums-Schlüsselattraktionen könnten sein:

Ausstellungen zu Nachhaltigkeit und Wissenschaft (z. B. wie erneuerbare Energien funktionieren, regenerative Landwirtschaft, Bedeutung der Biodiversität, nachhaltige Innovation, genetische Revolution, Digitalisierung, Robotik, künstliche Intelligenz, virtuelle Realität, Elektrofahrzeuge, Klimawissenschaft...)

Erlebnisattraktionen, um die Theorie in die Praxis umzusetzen und zu testen & zu lernen - diese könnten sogar von Universitätsstudenten vorbereitet und geleitet werden (wie sie es im MIT Museum in Boston tun)

Sonderausstellungen, die von NRW-Wissenschafts- und Technologieunternehmen gesponsert werden (z.B. Henkel oder Bayer, aber auch kleinere Start-up-Unternehmen)

Marktplatz für lokale, nachhaltige Produkte und Lebensmittel

Dachgarten mit dem Schwerpunkt Lernen über Landwirtschaft

IMAX-Kino für Dokumentarfilme oder interaktive Shows

Seminar-/Veranstaltungsort für regelmäßige Vorträge und Veranstaltungen zum Thema Nachhaltigkeit und Innovation. Es könnte genutzt werden, um Experten/Professoren/Innovatoren in die Stadt einzuladen, die ihre Ideen und Lösungen vorstellen

Restaurants mit nachhaltigen Konzepten, wie z.B. nur lokale Produkte zu verwenden und lokale Bauernhöfe vorzustellen

Bildungsveranstaltungen für Schulen, Digitalkurse für Senioren, Innovationsworkshops für Teenager / junge Erwachsene, Tutorials für nachhaltiges Leben für Erwachsene...

Auch aus architektonischer Sicht wäre es eine wunderbare Gelegenheit, ein umweltfreundliches und innovatives Gebäude mit viel Potenzial für Kreativität zu bauen. Sie könnten wahrscheinlich viele Stararchitekten finden, die an einem solch spannenden Projekt interessiert wären.

Zur Inspiration können Sie an das Science Center NEMO in Amsterdam (entworfen von Renzo Piano, es zieht etwa 700.000 Besucher pro Jahr an) oder das Exploratorium in San Francisco denken. Das Museum könnte freien Eintritt für in Düsseldorf lebende Kinder anbieten, um die in der Stadt lebenden Familien zu unterstützen.

Viele der anderen großartigen Ideen, die auf dieser Website zu finden sind, wie das "Umwelt ins Zentrum", könnten in dieses Konzept integriert werden, für ein wirklich ganzheitliches Erlebnis, das Düsseldorfer Familien, Schulen, Universitäten und umweltfreundliche Start-ups und Unternehmen unterstützen wird. Bitte ziehen Sie dies in Betracht, eine solche Gelegenheit kommt nicht oft.

V-Tech "Download Manager" issues

2 min read

Had a really bad experience trying to get the V-Tech "Download Manager" for their Magic Book 3D to work on Windows 10 - the application window did not resize and I had to put the screen size to a ridiculous 480x640 pixels to be able to get to some point where I could actually use the buttons in the application.

Somehow it detected the 3D Magibook on USB, but then, after waiting for the app to "load", and I was able to see the books to add the media of, the USB connection all of sudden disappeared and I was stuck again. I tried four times to get through the process to no avail.

Luckily I have a Macbook from work. I am not really supposed to use it for private applications, but in this case I was a little desperate. So I installed the "Download Manager" for Mac on it and had to mess a bit with disk access for it work, but was happy to see that all worked well on the Mac version of the application. First of all, a "firmware upgrade" window popped up and I had to go through the whole process.

I am suspecting that this firmware issue is the cause of the Windows problems. After the firmware upgrade, I was able to get the media for the new book we got our son, using the Mac app. But haven't tried with the Windows 10 version of the app.

Disappointing that the experience with the application on Windows 10 is so bad. So I wrote the customer service about it. Let's see what happens next.

My reasons to support the Gemini Internet Protocol

3 min read

Why do I believe Gemini is great for personal Internet presences? First of all, it's a real grass-roots initiative which I am very excited about.

If you're reading this, chances are high you are already using Gemini. But for history reasons and to share my opinions of Gemini I would like to offer you here some views of mine.

Collecting some of the strong-points of Gemini from my perspective of having some experience with Gopher and running personal websites.

Fast and lightweight

  • It's very easy on the system resources. So the protocol works really well on slower hardware without any problems. Hosting on a Raspberry Pi3 is easy-peasy.
  • Since there are no fancy design in Gemini capsules, it is really optimized for low bandwidth.
  • It should work really fine on a feature-phone, like for KaiOS. I don't believe there is a client yet for KaiOs at this time.
  • It's fairly easy to build clients and servers for the protocol.

Simple yet complete

  • The specifications provide enough functionality to do basically what you would expect to be able to do online.
  • Much lower learning curve compared to Gopher and HTML. You can start publishing Gemini pages within minutes.
  • Even-though the syntax is limited, it still gives enough playroom for creative expression.
  • Use of TLS certificates promises security and privacy.
  • It is more international than US-centric Gopher.
  • The procol supports the UTF-8 character set so any language can be used to publish sites in.
  • This should help make the protocol more popular in non-ascii wielding regions in the World.

Easy to publish

  • Content will be probably first of all stored in static text files which are future-proof and easy to maintain.
  • Many servers already available that require minimal technical skills.
  • Yes, you still need a server, but there are many collectives which you can join to facilitate this.


  • No popups, animations, videos, sound effects.
  • Focus on actual content instead of fluff and effects.
  • No advertisemens and commercial tracking.
  • No Facebook, Google or Twitter.


  • Power of formatting goes into the clients or readers. Like in the good old days of the early Web, people are expected to style the content to their own liking.
  • It's pure text, has simple navigation rules, so should be great for people with disabilities.
  • No JavaScript so you really see what you get.

And on top of this, the young Gemini community is driven to make this a success!

I'm sold.

ps. I published this first in plain text on my Gemini capsule and now that I copy paste this into a HTML document I can really tell just how easy it is to publish on Gemini.

I upgraded the camera hardware in my @fairphone

1 min read

Pretty proud that I was able to replace the camera modules in my 3 with the latest camera upgrades.

It is really awesome how Fairphone made a truly up-gradable phone possible and they made it really easy to take apart the phone.

The process does require steady hands and some nerve to execute. Detaching the screen from the frame was exciting. You need to get everything to "click" and not "break".

Everything came apart as planned and taking out the old modules and putting in the new was no issue. I did forget to take away one of the blueish protective covers of the front-facing camera module, after I had put the phone back together. So I had the exercise of taking apart the phone twice.

Followed the instructions from Fairphone themselves

The old modules are on their way to IFixit in Stuttgart Germany for refurbishment or recycling.

I've met my own fundraising goal, but my team still can use your support!

1 min read

To all my friends, thank you for supporting my head-shaving fundraiser for St. Baldrick's Foundation. I am amazed to share that I have already smashed my goal, with $1045 raised for childhood cancer research.

While I have met my goal, we are still $12000 short for the overall event goal of raising $50000, so I have increased my goal to $1500 – so if there is anyone still interested in helping, here is the link again 😃

We'll be going live on Facebook during the event, set for this Saturday at 18:00. @Jeff Neu, whose superhero 5-year old son Jake just beat cancer and rang the bell in June this year after three and a half years of treatment, is hosting the event. Many people will shave their heads and some will share their stories, and you are all invited to join if you are curious and have time.

This is the first time I do anything like this. While I am still a little nervous about shaving my head, I know it will be fun and I am grateful and humbled by the support you've all given me!

Why I am shaving my head bald on September 26th 2020

I am supporting the fight against childhood cancer!

Me before the shave

I am shaving my head to raise money for childhood cancer research. Sponsor me to help me reach my goal of a €1500.

I will shave my head to raise money for childhood cancer research. Sponsor me to help reach my goal of €1500.

Childhood cancer strikes more than children alone, it attacks whole families too. Did you know that almost half a million children will get cancer each year, and that in Europe and the US, one child out of 5 will die within 5 years from diagnosis? Did you know that there is little funding for childhood cancer research, with many treatment protocols dating 20, 30 or even 50 years? And that these treatment protocols are more intense than the ones for adults, and can last years?

I had no idea. But now that I do know, I want to help, because children can´t fight cancer alone. My fundraiser is in support of the St. Baldrick's Foundation, one of the most important childhood cancer research charities worldwide.

When you support them, you help fund critical trials and grants in more than 377 institutions in 30 countries.

This Saturday afternoon I will take part of a live event together with other families that will share their personal experiences with childhood cancer.

If you want, you can follow me live as I am getting my head shaved.

I am a bit nervous, but I know it´s going to be fun!

Please sponsor me to help me reach my goal of €1500 by this Saturday.

Twitter Interests page checkboxes are terribly bad implemented

It's almost that they don't really want you to edit your interests

2 min read

See this page if you have a Twitter account and want to control what kind of ads you get served:

It contained over 300 keywords, some of them I totally did not know why they would be added to my profile, some clearly wrong (Loud Orange Face was in there too) - so I started curating the list. The UX of this page is terrible.

In my case, there are over 300 checkboxes in a long list and there is no way to go through the process of unchecking the boxes easily because on EVERY click a POST request is sent to Twitter, which creates a brief moment where the user needs to wait before they can click on the next checkbox.

So obviously when a lot of people do this at the same time, especially now after watching the Social Dilemma documentary, clearly this page was not designed with that kind of traffic and server load in mind.

Was it done deliberately to discourage people to maintain this list? After 10 clicks or so the server is responding with error 503 ("Service Unavailable" or "over capacity") and none of the changes you make to the list is actually stored. I only noticed this after a reload. Yes, you can happily click further ignoring the error toast notification, but none of your changes will be saved.

This smells like a dark pattern, doesn't it?

Contact-less cash in the Real World?

How to hand out cash contact-less?

4 min read

Got a SwatchPay watch developed by Swatch and G+D Mobile Security, the other Saturday as a father’s day gift. I activated the payment function today using the Boon Virtual Debet Card I had registered for some months ago. Since WireCard in Germany is filing for bankrupcy there was some confusion and uncertainty.

The nice people at the Düsseldorf @Swatch store had to verify that it would work. It did. Some time later I paid contact-less for lunch with my new watch. Pretty sleek and COVID - safe.

Being able to pay contact-less is pretty great. But people on the street who depend on small change donations are really left out. I simply don’t carry cash and coins anymore with me. My credit-card size wallet also attest for that.

So how could we give small-change using a contact-less cash system? Similar to how in China vagrants use Alibaba Pay QR codes to beg for a small contribution on the street.

How would that work with a system that relies on NFC like SwatchPay? Give everyone who needs it access to NFC readers? What is the cheapest, most battery-efficient, weather-proof, solar-powered NFC reader payment terminal you know of?

It would have to be a system that works offline, but where the collections can be transfered into a system that exchanges for actual cash or exchange for food and clothes or shelter. People who have no identification should also still be able to use this system. The reader would have to taken care of as if it was actual cash.

How can we digitalize small-change donations in Germany where a large part of the population, luckily, still trusts cash in the hand more than electronic payment systems?

So the best solution is that we would reverse the devices. The people on the street all get “SwatchPay - like” watches or a similar thing like a card. They work without a battery, need only to be registered once. Then it would be up to everyone else to use their phones, or a portable NCF payments-capable device, to initialize the donation transaction. There would be an app for that. Just like the existing Boon or SwatchPay apps.

Instead of paying, we would be giving.

How much technology is inside the SwatchPay watches? It’s an NFC tag chip, similar to the ones we all have on our bank and credit cards.

How SwatchPay! Works (source)
Payments are made possible by the NFC chip, which is located on the back of the case. In a ring around the bezel, the watch has an antenna that catches the radiation, connecting the chip with the payment terminal. This is exactly the same technology as your bank card uses. You can activate your watch with your internet banking system. Setting this up costs about ten minutes. SwatchPAY! uses a method they call tokenization, which creates a unique “token” for the device. Simply store your credit or prepaid card on your smartwatch via the app (activation of SwatchPAY! watch in Swatch store) – the app is available for iOS and Android.

More insights in the tokenization can be found in the PDF: SwatchPay case-study by G+D Mobile Security.

Giesecke+Devrient Mobile Security is a company based in Munich, Germany

I’m not an engineer or have really investigated fully into the technical side of this, but the logic seems sound. What if we could tokenize everything this way?

And how we would avoid abuse is a whole different level of challenges to look into.
