A minimal Web Push example

Web push notifications allow users to opt-​in to asynchronous messages from a server to a web application. The message can be sent at any time, even when the web application or the web browser is inactive. This W3C standard, based on the HTTP/2 protocol, is now supported by Chrome, Firefox, Edge, Opera, and Safari – but not by iOS.

An Alexa skill for New York City transport service changes

Playing around with the idea of Alexa Skills based on live data feeds, I created an Alexa Skill which announces unplanned service changes of the New York City subway and bus lines, based on information provided by the Metropolitan Transportation Authority (MTA). This skill, available in English and German, was now certified and has gone live.

What web can do: a mobile speech-to-speech translator

In the 70s and 80s, some people thought that you could soon travel the world with a portable computer, only the size of a backpack, that would translate any spoken utterance to any other language. Nowadays, with the Google Translate App, you can easily do this with any mobile device. But is this also possible using only HTML, CSS, and Javascript?

What web can do today

Yesterday I tried to create a Progressive Web App displaying an artificial horizon over a live camera view and was wondering if this would be possible with a modern mobile web browser. During the research, I stumbled over several websites which you can use to test the hardware capabilities and their software support in web browsers and I wanted to share some links.

A 3D visualization of real-time earthquake data

This is a 3D visualization of real-time earthquake data gathered from the U.S. Geological Survey website. The data used in this example covers all earthquakes with a magnitude of at least 1 within the last 30 days. They are drawn into a template texture image file of the Earth’s surface according to the geographical position and the magnitude of the quake.
