So far, we’ve looked at staying ready for what’s changing, and building the kinds of modern applications developers are shipping now.
This week, we do more than just build a working version:
BUILD SYSTEMS YOU CAN TRUST
Shipping software is one thing. Shipping software that is reliable, maintainable, testable, understandable, and less likely to surprise you at the worst possible moment? That takes more, especially if you're leaning into AI assistance.
This week’s collection focuses on testing, debugging, architecture, code quality, workflow, and the engineering habits that help you build stronger systems with fewer nasty surprises. (Regardless of how much impact AI is having in your process.)
This Week's Featured Titles:
All of these are now 50% off with code Spring2026.
And remember: earlier weeks' collections are still on sale, too. (All titles included so far are listed below.)
Each week, we’re adding a new hand-picked collection to our Spring Forward Sale, and every featured title remains 50% off through the end of the sale.
Next week, Spring Forward continues with books on new languages, deeper paradigms, distributed systems, functional thinking, and advanced ways to reason about software.
