We use our computers and other devices everywhere.

So …
We often observe that something that needed help by an employee is now done by ourselves. Our automobile-affine friends have to fill in gasoline themselves since the seventies in Germany and now even the payment is often done with cards, so that there is no human on site, but only video surveillance, I assume. In …

This issue is quite controversial and it applies to laptops, tablets and smart phones.

Some of us still remember the times when it was recommended to avoid „special characters“ when writing on the computer. Some keyboards did not contain „Umlaut“-characters in Germany and we fell back to the ugly, but generally understandable way of replacing the German special characters like this: ä->ae, ö->oe, ü->ue, ß->sz or ß->ss. This was …

The idea of tablet computers is actually quite old and it has been tried a couple of times, at least up to prototypes. Probably a certain level of hardware and software was needed to make them both useful and affordable for enough people to become a mass product. This is actually a quite common thing. …

I have made an interesting observation in terms of user friendliness. Let’s call it an anti-pattern… I had booked a flight in the internet. Now the ticket was a number, which they sent to me by SMS. I went to the page of the airline and tried to do the check-in, in order to get …
