System Architecture

Technology companies were right to care so much about vendor lock-in in the last two decades. In the past, developers were burned by IBM, Microsoft, and Oracle services, often with few alternatives and price gouging. But to align your strategy so vehemently against the same type of lock-in in the

The relatively new io_uring subsystem has changed the way asynchronous I/O is done on Linux systems and improved performance significantly. It has also, however, begun to run up a record of disagreements with the kernel's security community. A recent discussion about security hooks for the new uring_cmd mechanism shows how easily requirements can be overlooked in a complex system with no overall supervision.

The big O notation is a way to understand and model complexity in algorithms. Let's first explain time complexity. Time complexity Time complexity shows how much time a task will take depending on some parameters. Let's take an example : def func(array): half = len(array)//2 return array[half] This

Docker has transformed the way many people develop and deploy software. It wasn't the first implementation of containers on Linux, but Docker's ideas about how containers should be structured and managed were different from its predecessors. Those ideas matured into industry standards, and an ecosystem of software has grown around them. Docker continues to be a major player in the ecosystem, but it is no longer the only whale in the sea — Red Hat has also done a lot of work on container tools, and alternative implementations are now available for many of Docker's offerings.
