📕 BOOK OF THE WEEK

This is such a great read! This book challenges the common misconception that we naturally act in very rational ways. Ariely explains that all the decisions we make are systematic and predictable, and therefore meaning that certain ‘senseless’ behaviors people tend to have towards things, aren’t senseless at all. They’re predictable.
As someone who has always been fascinated by human behavior and exploring what makes people "tick", I absolutely loved Ariely's book but I firmly believe that almost anyone could benefit from its material 💯

🛠 PROJECTS OF THE WEEK

The company 0x4447 builds products to increase standardization and security in AWS Organizations. They do this with automated pipelines that use well structured projects to create secure, easy to maintain and fail tolerant solutions. One of which is their VPN product – built on top of the popular OpenVPN® project, which has no license restrictions. You are only limited by the network card in the instance - Read more »

Run linux applications faster and safer than linux with open-source unikernels. Boot your first unikernel in seconds. Run on any cloud with no porting necessary. Easier than Kubernetes. Unikernels aren't just the future - they run in prod today - Read more »

Continuously monitor your AWS attack surface and evaluate services for configurations that can lead to degradation of confidentiality, integrity or availability. All results can be exported to Security Hub, JSON, CSV, Databases, and more for further aggregation and analysis - Read more »

DDS is a kubectl plugin to detect if active Kubernetes workloads are mounting the docker socket (docker.sock) volume. It looks for every pod in your Kubernetes cluster. If pods are part of a workload (eg Deployment, StatefulSet) it inspects the workload type instead of pods directly. It then inspects all of the volumes in the containers and looks for any volume with the path *docker.sock - Read more »

Kubernetes Application Archive (KAAR) - will recursively iterate through every file in the path and search for valid Kubernetes YAML. Next kaar will identify all container images referenced from the YAML. Finally kaar will archive the container images (local first, remote next) as well as the YAML from the local directory. The resulting archive will be saved as an OCI compliant container image that can be uploaded to any container registry - Read more »
