Install IOTStack on a Mac Mini

26th February, 20234th March, 2023 Marcel StörNo Comments

Let me help you install IOTStack on a Mac Mini. Why? Just because you can? Well, maybe. The true motivation, however, is that I had an un(der)used late 2012 Mac Mini at home that looked to be perfectly suited to run a few Docker containers.

However, due to its light-weight build it can carry only minimal weight. As a consequence, the tiny batteries only give you around […]

Look around the internet for “PyInstaller virus” and you will get lots of hits such as here, here, and here. In order […]

Why do we hate Greta instead of climate change?

23rd February, 202021st March, 2020 Marcel StörNo Comments

The climate summit has failed, but we are discussing Greta‘s train journey. Why do we do that? I care deeply about our planet. After all it is the only home we humans have. However, the longer I do, the more desperate I become. Too few people are willing to take, or at least support, the […]

The Lovebox – a gift from a maker

5th January, 202029th November, 2021 Marcel Stör28 Comments

The Lovebox is a project I learned about through a Make: magazine article from 2019. A reader notified ThingPulse – of which I’m a co-founder – because the project’s Arduino sketch relies on an open-source display driver provided by ThingPulse. I was immediately intrigued as the project involves electronics, software and classical woodworking. As a […]

Docker buildx – the best thing since sliced bread?

21st December, 201921st March, 2020 Marcel StörNo Comments

It’s 2019 – Flash is dead

21st May, 201921st May, 2019 Marcel StörNo Comments

Look Creately, if you want me to use your service – which I really wanted to – then it is not a good idea to require dead technology from a past era. Adobe Flash is really dead. Has been for a long time. Its fate was sealed back in 2007(!) when Apple refused loading it […]

Missing FaceTime dial pad on macOS

15th May, 201928th January, 2021 Marcel Stör1 Comment

Yes, Apple did forget to include a dial pad for FaceTime on the Mac. Says who? I do. Every now and then I make short posts about Apple macOS/Mac behavior I observe that annoys or delights me enough to spend time writing a post. It isn’t all perfectly thought through that gets the Apple design […]
