Create Images from Text with AI and Python

It all began with DALL-E, a machine learning model developed by OpenAI to generate digital images from natural language descriptions. But it is closed source and not open to the public. Yet on August 22, 2022, the AI art community was shaken by the release of an open-source alternative, Stable Diffusion, which you can install and run locally using modest hardware. Within days, PCWorld described it as the new killer app. And it surely is.

Google shuts down voice dialogs

As of June 13, 2023, Google will shut down all so-called "conversational actions" for their Google Assistant. Every action that involves a speech dialog, like food ordering, games, educational apps, story telling, every application that requires questions and answers, will be canceled.

With Chrome 81 Beta for Android, it’s now possible to use immersive Augmented Reality in the browser. I have again created two variations of the original demo source code to show what is easily possible.

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.

Why not to abbreviate the year 2020

The year 2020 poses a special problem that can make it easy for scammers to forge handwritten documents. This happens once in a century, the last time in the year 1919. It’s common practice to shorten the year when writing down a date. This year, however, could cause some legal issues and can leave you at risk of fraud.
