De CRNK Angler is een lichtgewicht fietshelm voor de meest voorkomende racefietser én voor dagelijks gebruik op een elektrische fiets. De Angler heeft wereldwijd meerdere prijzen gewonnen vanwege het unieke / elegante ontwerp. De vorm en opening van het roer zijn ontworpen om de aerodynamische en ventilatie te integreren. De grote openingen ronde de luchtcirculatie, vermindering van de luchtweerstand en verbetering van het koelvermogen. Deze fietshelm is opvallend licht van gewicht en is geschikt voor zowel mannen als vrouwen. Net als alle andere CRNK-helmen is de Angler een In-Mold-helm die zorgt voor maximaal comfort en maximale schokabsorptie. Deze helm weegt slechts 240 gram (M) /260 gram (L). Dankzij de slanke gepatenteerde magnetische gesp, open en sluit je de veiligheidsband onder je roer eenvoudig met een hand. Deze sluiting is niet alleen gemakkelijk in gebruik, maar zeer ook veilig. Daarnaast is deze Smart Fietshelm uitgerust met CRNK easydivider. Met dit verstelsysteem pas je de lengte van de veiligheidsbandjes eenvoudig aan om deze precies onder je oren bij elkaar te laten komen. De helm wordt standaard geleverd met twee verschillende pads, één memoryfoam pad en één 3mm antibacteriële pad inclusief muggennet. De memoryfoam-pad neemt in de eerste paar minuten in beslag nadat je de helm opzet, precies de vorm van je hoofd aan. Ieder hoofd is anders en een kleine bult of oneffenheid in je hoofd kan ervoor zorgen dat een roer niet prettig zit. Dit wordt door het memoryfoam volledig weggenomen. Bovendien biedt de dikte van het memoryfoam de helm een kleine rotatievrijheid die bij het opvangen van een impact het hoofd extra beschermt. De extra toegevoegde 3 mm antibacteriële pad is gemaakt van matig antibacterieel materiaal dat zweet absorbeert en het hoofd goed koelt. Deze pad leent zich daarmee uitstekend voor gebruikt op warme, zonnige dagen. Alle textielelementen die in contact komen met het hoofd zijn uitneembaar en wasbaar. Alle CRNK-helmen zijn vervaardig via een In-Mold-productie. Deze moderne en beperkte productiewijze biedt de volgende voordelen tov andere helm: Lichtgewicht en comfortabel: In-Mold-helmen zijn gemaakt door de schokabsorberende binnenlaag direct in de harde buitenschaal te smelten. Dit proces onmogelijk een lichter roer, wat krachtig aan comfort, vooral bij langdurig gebruik. Verbeterde Schokabsorptie: Door de integratie van de binnen- en buitenschalen, bieden CRNK In-Mold helmen betere schokabsorptie. Dit is een verbetering van de bescherming bij een impact. Compact Ontwerp: Alle CRNK-helmen hebben een slanker en gestroomlijnder ontwerp dan traditionele helmen met een aparte harde schaal en schokabsorberende laag. Duurzaamheid: Hoewel In-Mold helmen licht zijn, zijn ze ook verrassend duurzaam. De productie uit 1 stuk betekent minder ontbrekende punten die kunnen of breken. Betere ventilatie: CRNK In-Mold-helmen hebben betere ventilatie door het ontwerp en de lichtgewicht constructie, wat krachtig aan het comfort biedt tijdens krachtige activiteiten.Shipping Notes

Good overview of the leading Agentic Framework. Will become outdated quickly.
Format: Paperback
3.5 Stars rounded up.
Not a bad place to start if you need to get up to speed fast with Claude Code, understand its vast feature set, how it works under the hood, best practices, and the various agent primitives and how to get the most out of them. Agentic frameworks (Claude Code in particular) are quickly becoming table stakes for anyone working in tech, so it's best to start now.
I appreciated the author's ability to flesh out areas where Anthropic's documentation is lacking in depth and nuance, and for some not already working with Claude in their own repos, the fact that he provides "toy" repos where one can experiment with the tools without fear of consequence.
Where the book falls short is that most of the stuff in here is already covered pretty well already in Anthropic's docs, or even better so in their free "Skilljar" courses. What's more, some areas are given a bit of a shallow treatment, while others are a bit better done. So it's a bit inconsistent in that sense. Also, I can see how this book will quickly lose its currency in a few months at the pace things are going.
Ultimately, for me, the price of this book was a bit rich for my liking given the criticisms above. Still, I feel like I got valuable info that rounded up what I already knew from working with this agentic framework.
Recommended.

Practical AI Engineering Beyond Prompts — One of the Better Books on Agentic Coding
Format: Paperback
This book is not another “AI coding hype” book.
A lot of books talk about agents at a very high level. This one actually explains how things work when you try to use them inside real development workflows. That was the biggest difference for me.
What I liked most was the focus on context engineering, memory, MCP, hooks, subagents, and workflow orchestration instead of just “prompt better.” The author spends time explaining why long-running agent systems fail, how context grows over time, and why most AI coding setups become messy without structure.
The examples also feel practical — The HookHub project, Next.js setup, GitHub workflows, Claude memory files, and MCP integrations make it easier to connect theory with actual implementation.
From my retail domain experience perspective, I could immediately connect this to forecasting and pricing workflows.
For example:
* agents helping analysts generate specs before model development
* automated code review for promo forecasting pipelines
* isolated subagents for pricing, promotions, assortment
* persistent memory for business rules across teams
* MCP integrations to pull context from internal systems safely
The section around context isolation and subagents especially stood out because that is very similar to how enterprise forecasting teams already operate in reality. Different teams own different decision spaces.
One thing I appreciated: the author does not oversell AI.
There is a strong focus on constraints, context pollution, hallucinations, performance degradation, and workflow reliability. That makes the book feel grounded instead of marketing-heavy.
This is not for complete beginners though.
If someone has never worked with Git, APIs, coding agents, or LLM workflows, parts of the book may feel overwhelming early on. The author clearly says this is not beginner-level content.
Overall, probably one of the more practical books I have read recently on agentic coding systems.
Good for:
* software engineers
* AI engineers
* enterprise architecture teams
* technical product teams
* analytics leaders trying to operationalize AI development workflows
Especially useful if your organization is trying to move from “AI demos” into actual production workflows.

A Good Reality Check on How AI Agents Actually Work in Enterprise Systems
Format: Paperback
Most AI books stop at prompts.
This one goes deeper into how agent systems actually behave once you try to use them inside large workflows with memory, tools, permissions, automation, and multiple agents working together.
That part felt very relevant for healthcare and enterprise environments.
The book does a good job explaining why context engineering matters and how poor context handling creates hallucinations, inconsistent outputs, and degraded performance over time.
Honestly, that is one of the biggest problems organizations underestimate right now.
In healthcare workflows, context matters a lot:
* prior interactions
* business rules
* auditability
* escalation logic
* safety constraints
* tool permissions
* workflow boundaries
The sections on persistent memory, scoped context, subagents, and structured workflows connected strongly to that reality.
I work in enterprise analytics, and while reading this book I kept thinking about use cases like:
* pharmacy workflow automation
* prior authorization support systems
* coding assistants for healthcare engineering teams
* AI copilots for operational analytics
* agent-based escalation systems
* claims and workflow orchestration
The MCP chapters were also useful because they explain integration challenges clearly instead of treating tooling as magic.
What made this book stand out for me was the balance between implementation and architecture.
The author explains:
* why long contexts fail
* how context poisoning happens
* why isolation matters
* when parallel agents help
* when they actually create more complexity
That level of honesty is missing in many AI books right now.
Another thing: the examples are not overly academic — The Next.js project setup, GitHub automation, Claude desktop workflows, memory systems, hooks, and subagents make the learning process feel practical and hands-on.
One limitation: this book assumes technical background.
Someone completely new to coding agents, LLMs, Git, or development workflows may struggle in the first few chapters.
But for engineers, AI teams, enterprise architects, and technical leaders trying to understand where agentic coding is actually going, this book is worth reading.
Especially for organizations trying to operationalize AI safely instead of just experimenting with chatbots.

Great book! Practical and for developers that already use AI!
Format: Paperback
I purchased "Agentic Coding" by Claude Code due to my desire for an alternative to generic "Prompt Template" type resources related to AI-based development. This book accomplishes just that.
As opposed to merely viewing Claude Code as a "magic box", the author has explained how to utilize it in conjunction with other actual development processes. The authors' emphasis on "context engineering" (i.e., structuring data/information; managing knowledge in a project; guiding an AI agent to produce consistent results vs. producing random/unknown results) represents the strongest component of the book.
It should be noted that the book appears to be intended primarily for experienced developers with prior experience in software development and/or familiarity with AI-based development tools. Should you be familiar with Git, the command-line interface, and/or modern development processes, you may find this resource very helpful. Conversely, I did appreciate the fact that there were no novice-oriented descriptions provided throughout the book.
The aspect of the book that I found most valuable, however, is the extremely pragmatic nature of the material contained within. The examples illustrated through developing/maintaining CLAUDE.md files; utilizing Claude Code in combination with GitHub Workflows; employing MCP Servers; and creating multi-agent or sub-agent workflows all seemed to reflect a clear focus on "real world usage" rather than theoretical constructs. In addition, each chapter builds upon previous chapters in such a manner as to provide a logical progression through which the reader can easily understand and ultimately implement the concepts learned.
I also appreciated that the author included guidance on responsible utilization of the tool(s), as well as maintaining control over what changes are made by the agent. While numerous books regarding AI focus solely on what AI tools can accomplish, this book addresses both how to utilize these tools effectively in a real codebase, as well as responsibility and safety considerations.
In summary, this is not a book for individuals completely inexperienced in either programming or generative AI. However, if you are currently experimenting with tools such as Claude, Cursor, GitHub Actions, or MCP, this is likely one of the more useful and practical books available on the subject.
Recommended for software engineers seeking to transition from simply "prompting an AI" into establishing a repeatable/professional workflow process surrounding agentic coding.

⭐⭐⭐⭐ (so far)
Format: Paperback
I'm maybe a third of the way through this and already rethinking how I talk to coding agents. The reframe from "prompt engineering" to "context engineering" sounds like semantics until Marco walks you through why context poisoning, context clash, the Goldilocks zone for system prompts. That chapter alone reorganized something in my head. I keep going back to the line about garbage in, garbage out being the real reason agentic systems underperform.
The hands-on stuff lands well too. Building the HookHub project from scratch, wiring up Playwright MCP, watching Claude generate a CLAUDE.md file and then not automatically loading a memory file you just created — that moment where you expect magic and get silence instead? That's the kind of honest teaching I appreciate. It made the "why" behind memory hierarchies click.
