New MEAP! If you’ve ever stared at a class and asked “where does this code belong?” this book ends the guesswork. Author Enrique Medina Montenegro shows you how to take advantage of an architecture that gives every class exactly one reason to exist and one place to live. Following the principles of hexagonal architecture, you’ll build a running example application outward from the domain core. Each chapter adds a new layer, until the architecture enforces itself through executable specifications. [Read more]

New MEAP! Authors Walid Amamou, CEO of UbiAI.tools and Alessandro Negro, Chief Scientist at GraphAware, walk you through the complete process of building production-grade AI systems around Specialized Language Models. In it, you'll learn how to choose the right pretrained base models, and how to work directly with supervised fine-tuning and modern parameter-efficient techniques including LoRA, QLoRA, DoRA, adapters, and Half Fine-Tuning. You'll also explore reinforcement learning–based approaches such as RLHF and GRPO, along with knowledge distillation for transferring the capabilities of large teacher models into smaller, faster student models.

New MEAP! In this practical book written for readers with no previous GPU programming experience, author Harshwardhan Fartale introduces Triton’s innovative block-level programming model that replaces the tedious manipulation of low-level threads required by CUDA. Written for the latest hardware and LLMs, this book teaches GPU programming and Triton together, in Python, by profiling real workloads, identifying bottlenecks, and understanding why each optimization (coalescing, tiling, shared memory, reductions, and fusion) actually works.

New MEAP! Kargo is an Kubernetes-native application lifecycle orchestration tool that works alongside Argo CD to promote software builds, automatically moving software artifacts, container images, Helm chart versions, or Git commits from development to staging to production. While GitOps tools like Argo CD handle the "how" of deployment by reconciling the desired state, Kargo handles the "when" and the "where." This book shows you how to turn this continuous promotion of your software into a declarative, auditable discipline on Kubernetes. [Read more]
