What makes a software engineer truly effective? Beyond writing code, effectiveness comes from ethics, sustainable practices, collaboration, and the courage to adapt. The Effective Software Engineer guides you from clean coding habits to organizational empowerment, bridging the gap between developers and leaders.
Modern cybersecurity is no longer just about firewalls and antivirus. It is about architecture, governance, secure software delivery, cloud resilience, Zero Trust, AI security, and operational discipline.The Master Guide to Cyber Security brings these domains together into one practical enterprise-focused reference designed for modern security professionals, architects, engineers, and technology leaders.Built around real-world frameworks, secure-by-design principles, and current threat realities, this guide provides a structured roadmap for building secure systems in cloud-native and enterprise environments.
Java has changed. Have your patterns kept up?The Gang of Four wrote their landmark patterns in 1994 — when Java didn't exist, generics were a decade away, and "concurrency" meant carefully managing a handful of platform threads. Thirty years later, Java 21 through 25 has transformed the language: records replace boilerplate classes, sealed interfaces model closed type hierarchies with compiler enforcement, pattern matching eliminates entire categories of unsafe casting, and virtual threads make a million concurrent tasks not just possible but routine.Modern Java Design Patterns bridges that gap. Every classic pattern is shown first in its original form, then systematically rebuilt with the language features that exist today. The result is code that is shorter, safer, more expressive, and immediately recognisable to any team working on a modern Java codebase.
Learn how to design embedded systems the sane way: on your Linux host, with modern C++, predictable timing, clean interfaces, and no unnecessary complexity.
Residuality Theory is a new way to think about the design of software systems that explains why we experience design the way we do, why certain things seem to work only sporadically, and why certain architects get it right so often regardless of which tools they use. A new, scientific approach is defined that fuses Software Engineering, Complexity Science, and Philosophy to produce an entirely new way to think about how to design software. The result is a theoretical base that allows architecture to finally become its own discipline.
Software and infrastructure only create value when they pull in the same direction as the business. This book shows IT leaders how to get there: from shaping IT strategy and the architecture roadmap to the daily discipline of IT and architecture governance, all built on a pattern-based approach that adapts to your organization rather than forcing it into a template.Grounded in established frameworks such as TOGAF, COBIT, and ITIL, it pairs solid fundamentals with numerous real-world examples — and gives growing weight to compliance and IT security, now central concerns of any IT management agenda.This English edition is based on the German standard work on the subject, fully revised in its 4th edition (late 2024). It is current with TOGAF 10 and reflects recent developments in business-oriented enterprise architecture — including the open-source tool EDGY and patterns for digital strategy — alongside the latest trends in IT risk management and cybersecurity architecture.
Uncover the fundamentals of GPU architecture and assembly programming with Advanced GPU Assembly Programming, a resource designed for enthusiasts and professionals who want to explore the intricate workings of modern GPUs.

As an academic, I like Leanpub because it lets me write and get my ideas out there quickly. Leanpub is simply the best place for publishing my books.
Leanpub's book-creation tools allowed me to focus on creating the types of books I wanted to write instead of worrying how to create my own book publishing toolchain. I have never regretted using Leanpub to publish my ebooks.
Leanpub takes the pain out of publishing. They provide the tools, you provide the books and then magic happens.
I love using Leanpub because I can write my book using simple Markdown notation. Leanpub let's me focus on my content and they handle the rest.
Leanpub is a game changer for independent authors, removing the hassles associated with formatting, book production, and electronic sales, freeing up the time to do what we do best: write.
Leanpub helped me achieve my goal of publishing a book. Its simple, easy to use interface got my book up and making money within weeks, I love Leanpub!
Leanpub helped me gauge interest in my book, get payments early on when it was only a few chapters, and has got me a bunch of sales just from people browsing around the site.
Leanpub helps me see my books as I write them. Even better, I can find readers early, to read my books and offer suggestions. I can pivot, if I see the need.
Leanpub made it simple for me to run with my book idea and build my reputation in the Ruby community. I went from first draft to first sale in days, not months or years.
Four years ago, I joined Leanpub to just give it a try. Today, over 28,000 book sales later, I cannot help but say that I'm the biggest Leanpub fan on this planet!
Leanpub makes publishing your own book super easy. The fact that you can release updates continually helps with the mindset of getting a minimum version out ASAP and then iterating to improve.
I earn more royalties from my books on Leanpub than I do with well established publishers or through Amazon (which I publish on thanks to Leanpub's mobi conversion).
Leanpub allows me focus on content, takes care everything else and offers an amazing author royalty. It’s a fantastic platform for writing and publishing books.
I love that Leanpub makes writing and publishing a beautiful book so simple. I no longer spin my wheels with layouts and formats - Leanpub gets out of the way when it's time to write, and then automates everything when it's time to publish.
With Leanpub, the first person who purchased my book for $9.99 almost two years ago (and only received a preface, and two short intro chapters) has had access to almost every bit of knowledge I've gained in those two years, and *that's* the value.
Simple and lean, forces me to focus on writing and marketing, and pays excellent royalties.
Leanpub forces you to focus on writing and gives you immediate feedback. Allowing Leanpub to take care of the curation and delivery helped me focus on shipping my book.
While most eBook exporter apps today can generate PDF files and many support ePub, there's one tool we recommend above all after trying 8 of the most popular: Leanpub.
