Platform Strategy
Gregor HohpeDeveloper platforms promise to rewrite the laws of IT physics: they boost innovation through standards; they speed up development while assuring compliance; and they reduce cognitive load without restricting choice. Building such an in-house platform, or even deploying one, is far from easy, though. This book condenses a decade of building and rolling out platforms into practical advice for platform teams and users.

Residues: Time, Change, and Uncertainty in Software Architecture.
Barry M O’ReillyResiduality 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.

Create Your Own Blockchain From Scratch
There is a very strong correlation between the popularity of Blockchain and Bitcoin (cryptocurrency). Today, many people use these words interchangeably. The fact is that Bitcoin is a product of Blockchain. Blockchain can exists without Bitcoin and not vice versa. The best way to learn about the Blockchain is to create a cryptocurrency yourself.

Leanpub: Publish Early, Publish Often
On Leanpub, you can publish your book while you write it, and earn 80% royalties.
We call this Lean Publishing, and it's why Leanpub exists. Lean Publishing is the act of publishing an in-progress book using lightweight tools and many iterations to get reader feedback, pivot until you have the right book and build traction once you do. You can learn more about Lean Publishing in The Lean Publishing Manifesto, or watch the Tools of Change conference talk about it. There's even a book about these ideas, which still guide us today.
Leanpub is a magical typewriter for authors: just write in plain text, and to preview or publish your ebook, just click a button. On Leanpub, you can write in Markdown and generate your ebook with one click. (Markdown is really easy: everything you need to know is in the template we set up for you when you create a new book.)
Now, if you have completed a book already or if you have a writing workflow you prefer, you can also just upload your own PDF or EPUB files and click a button to publish them.
Whether you're writing in Markdown or uploading PDF and EPUB files, Leanpub is the best place to write, publish and sell in-progress and completed ebooks, with coupons, variable pricing, bundles and more. Besides how easy we make everything and the excellent support we provide, the other reason authors love Leanpub is our 80% royalty rate.
We pay 80% royalties on purchases of $7.99 or more, and 80% royalties minus a 50 cent flat fee on purchases between $0.99 and $7.98.
You earn $8 on a $10 sale, and $16 on a $20 sale.
So, if we sell 5000 copies of your book for $20, you'll earn $80,000. Yes, some authors have already earned much more than that on Leanpub. In fact, authors have earned over $14 million USD writing, publishing and selling on Leanpub.
Finally, Leanpub also supports publishing online courses, using the same Lean Publishing approach and Markdown-based workflow that we use for ebooks, and paying the same 80% royalties! To learn more, just create a course: the new course will contain a template which shows you how to get started.
Leanpub Promotes Authors
Leanpub does a lot to promote authors and their books. We constantly promote books on social media, especially new releases and bestsellers. We create short videos to help promote selected new books, and you can apply to have us record and produce a book launch video with you - for free. Leanpub co-founder Len Epp also records in-depth long-form interviews with select authors for our Frontmatter podcast, and we provide you with a range of marketing tools, from custom coupons to affordably-priced sponsored spots in our Weekly and Monthly newsletter sales.
Reader Memberships
Leanpub reader memberships support Leanpub authors and Leanpub!
Leanpub is a platform where authors self-publish ebooks and online courses. We're a bootstrapped startup, and we launched in 2010.
Leanpub Reader Memberships are a great deal. They give you you free access to about 2000 books on Leanpub that are only free with membership. This includes hundreds of books about computer programming, data science, software architecture and more!
Besides being a great deal, Reader Memberships support Leanpub authors! Specifically, 50% of the money from Reader Memberships is paid as royalties to Leanpub authors.
The Leanpub 60 Day 100% Happiness Guarantee
Within 60 days of purchase you can get a 100% refund on any Leanpub purchase, in two clicks.
Now, this is technically risky for us, since you'll have the book or course files either way. But we're so confident in our products and services, and in our authors and readers, that we're happy to offer a full money back guarantee for everything we sell.
You can only find out how good something is by trying it, and because of our 100% money back guarantee there's literally no risk to do so!
So, there's no reason not to click the Add to Cart button, is there?
