Welcome to issue 271 of Programmer Weekly. Let's get straight to the links this week.
Quote of the Week
“Scope doesn’t creep, understanding grows.” – Jeff Patton
Reading List
The post explains the core hardware concepts and programming techniques behind state-of-the-art matrix multiplication (matmul) kernels on NVIDIA GPUs, focusing on architecture, GPU assembly, and advanced kernel design methods like warp-tiling and tensor core utilization. It is designed to provide a detailed but accessible introduction to how GPUs achieve high-performance matmul operations critical to AI workloads like transformers.
Learn how Amazon built the backbone of the modern web that scales to 1 PB/s and 150M QPS on commodity hard drives.
Modal reverse-engineered Flash Attention 4, a new CUDA kernel for Transformer attention layers, revealing how it achieves ~20% speedups via asynchronous pipelines and math approximations. They show how FA4 shifts complexity from algorithm to execution infrastructure using warp specialization, approximate exponentials, and smarter online softmax techniques.
Netflix’s Write-Ahead Log (WAL) is a distributed system that logs all data changes before applying them, ensuring strong durability and making reliable recovery from failures possible. This architecture helps guarantee data consistency and lets Netflix’s data platform deliver changes robustly to downstream consumers, supporting resilience at large scale.
Max Mynter’s blog details his 18-month strategic journey to becoming a research engineer at a leading LLM lab, emphasizing a blend of long-term skill-building, networking, and tactical job application processes. He highlights the importance of clear goals, building rare and valuable skills, strategic networking, and disciplined interview preparation to successfully transition into highly competitive AI roles.
Watch, Listen
The video features Richard Sutton, a pioneer of reinforcement learning, who argues that large language models (LLMs) are a dead end for true AI because they lack continual learning and goal-directed behavior. He emphasizes that real intelligence requires learning from experience with clear goals and suggests future AI will need new architectures enabling on-the-fly learning beyond the current LLM paradigm.
The video explains how Revolut’s small DevOps team of 15 engineers built an automated, developer-centric platform that supports over 12,000 employees and 1,200 microservices, enabling fast, scalable deployment and operation of their systems. Key innovations include a centralized system catalog, automation of repetitive tasks, enforcement of architectural patterns, and self-service capabilities to maximize developer velocity and reduce noise from alerts.
The video provides a conceptual understanding of Kafka, explaining why it was developed to solve scalability and performance issues in microservices architectures. It then offers a hands-on tutorial building a simple Python application with Kafka, demonstrating how to set up Kafka with Docker, create Kafka producers and consumers, and run a complete event-driven data flow.
