During the last few months, I spent a significant amount of time reviewing system modeling literature and exploring the current advancements in this area of research. Specifically, my goal was to apply advanced machine learning including deep learning techniques to efficiently represent system events in a euclidean space and detect
The goal of this post is to provide an in-depth discussion of BPF ring buffers, covering their internals, including memory allocation, user-space mapping, locking mechanisms, and efficient data sharing with user-land processes. This article is quite detailed, and I understand that some of you may not want to spend minutes
Writing performant, portable, and correct parallel programs in multiprocessor systems or SMP, where each processor may load and store to a single shared address space, is not trivial. Programmers must be aware of the underlying memory semantics, i.e. the system optimizations performed by the clever beast hardware or cpu.
Observability represents the ability to measure how well the internal state of a system can be inferred solely by its external outputs. Observability and the challenges associated with it is by no means a new problem and have existed for decades. Observability is a necessary precursor to ensure the reliability
