Camunda BPM Camel 0.5.0 Released – External Task Support
The community extension Camunda BPM Camel seamlessly connects Camunda BPM and the integration framework Apache Camel. Next to minor changes, the new release adds support for consuming Camunda’s external tasks (introduced in Camunda 7.4.0) in the form of a Camel route endpoint. This is another level of technical decoupling and brings a lot of advantages.

Argon2 as password-hashing function in Camunda
Introduction On the new version of the Camunda Engine Platform (7.7) the user passwords, which are stored in the database, are by default hashed with a SHA-2 family algorithm.

For someone who needs a more secure hashing algorithm Camunda introduce a new API, which allows to customize and exchange the default hashing algorithm. In this blog post I will present this customization and will use argon2 as hashing algorithm.

Conway’s game of life
The holidays are upon us, time for a lighter kind of blog post: Conways’s game of life on a Raspberry Pi. Conways game of life can be modelled by the following bpmn and dmn: In order to see what is happening the Raspberry Pi was hooked up to a 8×8 LED matrix (can be bought e.g at Adafruit together with the Raspberry Pi 3, breadboard and jumper wires).

Camunda 7.6 got released few weeks ago and it comes with many new exciting features. One of them is the extended Batch Operation feature and within this post I am gonna tell you what you can do with it and why it is so useful. Before I outline some really good use cases for Batch Operations let’s have a look what the concept actually means.
