JWT: Encoded or decoded security claims
JWT: Encoded or decoded security claims
Last week, I wrote about Db2 support for JSON Web Tokens (JWT). Today, I have a small follow-up with some reading material on JWT and related topics like JOSE, JWS, JWK as well as OAuth and OpenID Connect.

Db2 Security: Configure JSON Web Token (JWT) authentication

Since V11.5.4, Db2 allows to consume JWT (JSON Web Token). The business case is to support SSO (single sign-on). You can configure Db2 to accept access tokens issued by external Identity Provider (IDPs), including the IBM solutions or open source projects like gluu. V11.5.5 brought some JWT improvements, e.g., support for multiple labels. On a recent Friday, I set up my Db2 Docker container to accept JWTs, not those issued by an external identity service, but my own.

OBS on Linux: Green screen and virtual camera for video conferencing

OBS Studio: My monkey enjoys the beach
Similar to many of you, part of my work and hobbies consists of video conferencing. For some time now, I have been using OBS Studio (Open Broadcaster Software) to create a virtual camera on my Linux system. Recently, I had to upgrade my kernel. It required to recompile some file and reminded me that I wanted to blog about it. As usual, this is how I remember all the interesting stuff. So what is needed to create a virtual camera with OBS Studio and can you use a green screen for some beach feeling like shown?
