UnisonDB is an open-source database designed specifically for Edge AI and Edge Computing.

It is a reactive, log-native and multi-model database built for real-time and edge-scale applications. UnisonDB combines a B+Tree storage engine with WAL-based (Write-Ahead Logging) streaming replication, enabling near-instant fan-out replication across hundreds of nodes — all while preserving strong consistency and durability.

Trixter is a high-performance chaos proxy designed for injecting network faults at the TCP layer. In essence, it’s a TCP proxy that sits between a client and server, forwarding traffic but intentionally sabotaging it according to your specifications.

My on-call experience started by accident in the mid-2000s. It was 5pm on the Friday at the end of my first week of employment as a software engineer at a financial services company in London. I was in the process of closing down my IDE for the weekend when my boss sauntered up to my desk, grinning awkwardly. He was carrying an IBM Thinkpad, a Blackberry, and the unmistakable burden of a man who needed to call in a favour.

Kubernetes-native scale-to-zero with zero traffic loss, no code changes, and direct integration with kubernetes resources

The OpenTelemetry Operator is an implementation of a Kubernetes Operator.

Zarf eliminates the complexity of airgap software delivery for Kubernetes clusters and cloud-native workloads using a declarative packaging strategy to support DevSecOps in offline and semi-connected environments.

The SR-IOV Network Device Plugin is Kubernetes device plugin for discovering and advertising networking resources in the form of:

- SR-IOV virtual functions (VFs)
- PCI physical functions (PFs)
- Auxiliary network devices, in particular Subfunctions (SFs)

which are available on a Kubernetes host

"Oops, I accidentally deleted my Docker registry. Can I get my images back?" YES. This tool does exactly that.

A cautionary tale about AWS VPC networking, NAT Gateways, and how a missing VPC Endpoint turned our S3 data transfers into an expensive lesson.

Postgres has an awesome amount of data collected in its own internal tables. Postgres hackers know all about this - but software developers and folks working with day to day Postgres tasks often miss out the good stuff.

The Postgres catalog is how Postgres keeps track of itself. Of course, Postgres would do this in a relational database with its own schema. Throughout the years several nice features have been added to the internal tables like psql tools and views that make navigating Postgres’ internal tables even easier.

Today I want to walk through some of the most important Postgres internal data catalog details. What they are, what is in them, and how they might help you understand more about what is happening inside your database.
