Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

How to setup a containerized python environment? Function as a Service or an alternative solution for a Python execution environment.
Firstly, I tried Rundeck and Apache Airflow. They are complete overkill for what I want to do. Then I found Cronicle which is light enough, besides it can pull double duty as a general purpose scheduler.

Important Advisory: PagerDuty Process Automation On Prem / Rundeck Key Pair Misconfiguration
Yesterday we posted a Security Advisory to Github for a critical vulnerability in Rundeck Community and Rundeck Enterprise Docker images, versions 4.0 and earlier. Those Docker images contained a pre-generated SSH key pair in the default file path. If that key was used to configure SSH access to hosts, they would allow access to anyone with the exposed private key.

looking for suggestions for a web interface for ansible with scheduling.
Never used it myself (we're currently working on deploying Tower) but I've heard that Rundeck is the goto for your exact use case: "Tower, but less heavy". I looked at it when evaluating for my current job and it looks like a good middle of the road solution and looks way easier to deploy than AWX. The tradeoff is that since it's not custom built for Ansible you can automate lots of other things with it (like just bash scripts and the like) but you get less of the Ansible-specific integrations and tooling that Tower offers.

Rundeck 3.4.5+ breaks the "Run Job Later" function
Hi! This fix solves the bug, is ready to be included in the next release. Regards.
There is already an open GitHub issue on this, but I wanted to mention it here as it can cause some nasty surprises for those unaware.

Easy Guide to Integrating Kafka: Practical Solutions for Managing Blob Data
To use Kafka, we also need to deploy a service that keeps configuration informations such as Zookeeper.

Fault Tolerance in Distributed Systems: Strategies and Case Studies
Failure Detection and Recovery It’s not enough to have backup systems. It’s also crucial to detect failures quickly. Modern systems employ monitoring tools and rely on distributed coordination systems such as Zookeeper or etcd to identify faults in real-time: once detected, recovery mechanisms are triggered to restore the service.

Analysing Github Stars - Extracting and analyzing data from Github using Apache NiFi®, Apache Kafka® and Apache Druid®
You can install Kafka from https://kafka.apache.org/quickstart. Because Druid and Kafka both use Apache Zookeeper, I opted to use the Zookeeper deployment that comes with Druid, so didn’t start it with Kafka. Once running, I created two topics for me to post the data into, and for Druid to ingest from:

Use AWS CloudFormation to create ShardingSphere HA clusters
Please note that we use Zookeeper as the Governance Center.

How to choose the right API Gateway
Next, review deployment complexity such as DB-less versus database-backed deployments. For example, Kong does require running Cassandra or Postgres. Apigee requires Cassandra, Zookeeper, and Postgres to run, while other solutions like Express Gateway and Tyk only require Redis. Apache APISIX uses etcd as its data store, it stores and manages routing-related and plugin-related configurations in etcd in the Data Plane.

ElasticJob 3.0.2 is released including failover optimization, scheduling stability, and Java 19 compatibility
ElasticJob achieves distributed coordination through ZooKeeper. In practical scenarios, users may start multiple jobs in the same project simultaneously, all of which use the same Apache Curator client. There are certain risks due to the nature of ZooKeeper and the callback method of Curator in a single event thread.

Casper Kafka Event Store Pt 1
For now we just need to know that Kafka will be running n brokers acting as a cluster. The Kafka cluster will use Zookeeper to orchestrate the brokers.

Setting up a local Apache Kafka instance for testing
We spin up a Zookeeper instance at port 2181 internally within the Docker network (i.e. not accessible from the host)
