Water pressure on lock gate
The document discusses water pressure on lock gates used to transfer boats between different water levels on opposite sides of dams. It describes how lock gates work and how water pressure creates forces on the gates. Specifically, it explains that water pressure creates a force P on each gate, and the gates exert an equal and opposite reaction force F on each other. The total pressure is shared between the top and bottom hinges of each gate. Mathematical equations are provided to calculate the individual reaction forces on the top and bottom hinges based on the water levels, gate dimensions, and other parameters. As an example, calculations are shown to determine the force acting on each gate for a given lock gate configuration and water levels.
Pressure
The total pressure on an immersed surface is the force exerted by the static fluid and is always normal to the surface. The center of pressure is the point where the total pressure force is applied. The document defines equations to calculate the total pressure and center of pressure for horizontally immersed, vertically immersed, inclined, and curved surfaces based on factors like the specific weight of the liquid, area of the immersed surface, depth from the liquid surface, moment of inertia, and angle of inclination.

Lock
A lock is a device used on canals and rivers to raise and lower boats between stretches of water of different levels. It has a fixed chamber that can vary in water level. When a boat enters an empty lock, the chamber fills with water from the upper level, raising the boat. When full, the boat exits through the upper gates. For a boat going downstream, the process is reversed - it enters a full lock, which then empties to lower the boat to the lower level. Pound locks, first developed in China, have upper and lower gates that control water levels and allow boats to pass through. They are the most common type of lock used today on canals and rivers worldwide.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Securing your Kubernetes cluster_ a step-by-step guide to success !
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
