What's funny is that DRY was first popularised in the Pragmatic Programmer[0] book, and "coincidental" duplication is explicitly addressed right there on page 34, "not all code duplication is knowledge duplication... the code is the same but the knowledge is different... that's a coincidence, not a duplication."

I believe this was added in the 20th anniversary edition to address the overuse of DRY following the original edition.

Fortunately, there is a newer edition ;) The Pragmatic Programmer, 20th Anniversary Edition: https://www.amazon.com/Pragmatic-Programmer-journey-mastery-...

+1 on CI & automated tests BTW.

Hacking is about solving a series of specific problems. Reading will give you direct insight into another's pre-established knowledge, but it's probably not relevant, and it may not be correct.

Code kata in my opinion is the superior way to learn. Code through practice and repetition, just like every other skill.

Ironically, you can read a book about it https://www.amazon.com/Pragmatic-Programmer-journey-mastery-...

I didn't see any mention of in a quick look through the linked website, but the book "The Pragmatic Programmer" is one of the best resources you'll find for making the most out of text-based tools. PP goes a little beyond that, too, it's not the book's sole focus, but it's a major one, and the book is a classic: https://www.amazon.com/Pragmatic-Programmer-journey-mastery-...

I agree, but I found some of the relevant practices really hard to adopt. For example, how do you setup your tooling to put documentation in one place so it can be used for a wide variety of purposes, like code comments and relevant customer docs? Is that realistic from both the dev and user-facing perspectives?

Buying from the pragprog site gets you a 50% discount on the hardcover when it comes out, if you have any interest in the paper version.

The publisher also gets more money from the sale (since they don't have to give Amazon a cut), and they have 20-30% off sales several times a year. Their twitter[1] is a good place to learn about the sales, and the publisher's site is http://pragprog.com

A new version of "The Pragmatic Programmer" recently came out. [EDIT: not available yet, only preorder at amazon, beta version available at pragprog.com.] That book is all about tools and methods that a self-taught programmer should look into:

For me, that Amazon page is listing it as a pre-order, without any release date. And all the other versions (Kindle, Paperback) are the 1st edition instead of the 2nd.

Very frustrating, as I considered the first edition to be essential and upon reading your comment, instantly went to purchase the 2nd edition.

Edited to add: Found a date, Amazon is listing it as October 21, 2019.

It is available in beta at pragprog : https://pragprog.com/book/tpp20/the-pragmatic-programmer-20t...

Sorry, I thought I'd read a review of it already, so just didn't look closely to see it wasn't available yet.

It looks like you can get a DRM-free beta version of the ebook on their website, with free upgrades to published version once it's finalized: https://pragprog.com/book/tpp20/the-pragmatic-programmer-20t...
