| Hi there,  Computer scientist Ralph Johnson famously defined software architecture as "the important stuff (whatever that is)." If you are in the technology field (and are old enough to remember books), you're probably familiar with O'Reilly books—they're the ones with animals on the covers that crystallized emerging technologies and launched careers. The ones that cover "the important stuff." You'll still find O'Reilly books on the bookshelves of the alpha geeks and innovators. But more and more, we find people are accessing them (along with live courses, videos, interactive tutorials, etc.) online at O'Reilly. As an O'Reilly subscriber, you'd be able to access all O'Reilly books—as well as thousands more from over 200 of the world's best publishers—24/7 from the device of your choice. Want a taste? Here are chapters from six of our best-selling books, free. This compilation will help you learn the architectures you need to better plan, code, test, and deploy applications. The O'Reilly Team P.S. We still love our books in paper. See some of our current best-sellers on Amazon here. |
