All the previous tutorials in this series on JSON web tokens used a secret or private key in combination with a signing algorithm to create a token’s signature. But in contrast, the JWT specification also allows unsigned tokens. This supports use cases where a token’s content is secured …

In the previous two tutorials, you've learned how to set up custom fonts on Android the modern way. Either as fixed font style (such as Noto Serif bold) or as font family (such as Noto serif in several weights). However, so far you've only used XML designs to configure app …

In the last tutorial, we've explored the modern way of implementing custom fonts on Android. However, it broke the support for dynamically changing the font style and weights (for example, bold or italic). In this tutorial, we'll fix this drawback and configure a font family with different styles. {{outline}} {{video} …

Last week we’ve learned about CoreOS’ components and technologies within the ecosystem. This week, we’re directly diving into the practical part and get our hands dirty. If you read the first post, you already know that CoreOS is an operating system geared towards high-availability. Setting up a cluster …
