You’re a Senior Frontend Developer. An intern asks you: ''How would you implement a design system so it stays consistent and scalable over time?" Here how to achieve that:
You’re in a backend interview. They ask: “How would you ensure data consistency across multiple microservices?” Here’s a clear, interview-ready approach:
I switched to DevOps Engineering 4 years ago! It was the best career move I ever made. If you want to start today, here's a roadmap:

Great tech interview question: Design logger rotation So many opportunities to go in depth. What is the size of files? How many files to keep? How to name/number files? How to optimise it for concurrent logging? How to handle terabytes of logs?

MobileLLM: nice paper from @AIatMeta about running sub-billion LLMs on smartphones and other edge devices. TL;DR: more depth, not width; shared matrices for token->embedding and embedding->token; shared weights between multiple transformer blocks; Paper: arxiv.org/abs/2402.14905
Totally spot on!
