The ByteByteGo newsletter article, drawing from the Netflix Tech Blog and Apache Cassandra documentation, explains how Netflix manages the massive scale of user viewing data generated daily. Initially relying on Apache Cassandra, Netflix faced challenges with increasing data volume from global expansion, new features like video previews, and inefficient data retrieval. To address these issues, Netflix redesigned its storage architecture by categorizing data, sharding it based on type and age, implementing optimizations like compression and caching, and automating data movement. This evolution allowed Netflix to improve storage efficiency, enhance retrieval speeds, and ensure a consistent user experience despite exponential data growth.

This YouTube transcript from a Stanford CS229 lecture provides an overview of building large language models (LLMs). It outlines key components for training LLMs, emphasizing architecture, training loss, data, evaluation, and system considerations. The lecture distinguishes between pre-training, focused on modeling internet text, and post-training, aimed at creating AI assistants. The discussion covers essential concepts like tokenization, evaluation metrics such as perplexity, and the critical role of data acquisition and scaling laws in LLM development. Furthermore, it touches upon post-training techniques like supervised fine-tuning and reinforcement learning from human feedback (RLHF), including its simplification through Direct Preference Optimization (DPO). Finally, the transcript briefly introduces system-level optimizations for efficient GPU utilization in training these large models.

This podcast from OWASP serves as a guide for secure code review, aiming to help organizations build self-defending applications. It outlines the importance of manual code review in identifying security and logical flaws, often surpassing automated tools and penetration testing alone.
