This is a submission for the Hacktoberfest Weekend Challenge: Build for a Friend Aman is my classmate. We're both in final-year B.Tech, and like everyone in our batch he's preparing for campus placements: SDE-1 roles, which means technical rounds on DSA, DBMS, Operating Systems, Networks and OOP, plus an HR round. When I asked him how his prep was going, he wasn't sure. He was putting in the hours, but he couldn't tell which topics were actually weak. Nobody was asking him questions and telling him what he'd missed, so he kept revising the topics he was already comfortable with.

Eventually I had the very predictable software engineer thought of, “I could probably just build this myself.” So I did!

Kubernetes SR-IOV Multi-Rail GPU Networking: Missing Route Configuration for Cross-Rail Communication

Introduction: Mastering Cross-Rail Communication in Kubernetes SR-IOV GPU Networking In high-performance computing environments, GPU-accelerated workloads drive advancements in AI, machine learning, and scientific simulations, demanding robust and efficient networking architectures. Kubernetes, coupled with Single-Root I/O Virtualization (SR-IOV), has become a cornerstone for managing GPU resources at scale, offering low-latency and high-throughput connectivity. However, as demonstrated in our case study, configuring cross-rail communication in multi-rail GPU setups presents significant challe

Golang REST API: Handling Undefined vs. Null Attributes in JSON PATCH Requests with Gin and Validator

Introduction In the realm of REST APIs, particularly those built with Golang, Gin, and Validator, the distinction between undefined and null attributes in JSON payloads is not just a nuance—it’s a critical operational requirement. This distinction directly impacts how data is manipulated during PATCH requests, where the intent behind an attribute’s absence or explicit nullification must be unambiguously interpreted. Failure to differentiate these states can lead to data inconsistencies, loss of critical information, and compromised system integrity, as the API may incorrectly overwrite, delete
