I love your books on regex...As a student from the Digital VLSI space, it is indeed useful now and definitely in the future. It's really well written and really easy to understand the examples.

feedback on reddit

It's very thorough, written with care, and presented in a way that makes sense. Even as an intermediate Python programmer, I found use in this book.

Step up your cli fu with this fabulous intro & deep dive into awk. I learned a ton of tricks!

Your Practice Python Projects book is really helping me to reinforce my knowledge and mastery of Python as I'm learning.

In my opinion the book does a great job of quickly presenting examples of how commands can be used and then paired up to achieve new or interesting ways of manipulating data. Throughout the text there are little highlights offering tips on extra functionality or limitations of certain commands. For instance, when discussing the shuf command we're warned that shuf will not work with multiple files. However, we can merge multiple files together (using the cat command) and then pass them to shuf. These little gems of wisdom add a dimension to the book and will likely save the reader some time wondering why their scripts are not working as expected.

Literally was having a mini-breakdown about not understanding Regex in algorithm solutions the other day and now I'm feeling so much better, so thank YOU! I genuinely feel like I'm developing the skill for spotting when and where to use them after so much practice!

This Ruby one-liners cookbook is incredible. Pretty mind boggling all the stuff you can do.

Hi, great work releasing this! Trying to explain vim concisely is always an interesting challenge and I had a great time reading your attempt in this book. I always find it really interesting on how people try to group certain vim functions in a way that makes sense to people that don't use vim. I think you cover that idea pretty well in your 'Vim philosophy and features' section whilst not making it overly abstract and keeping it relatable.

Vim Reference Guide

This is intended as a concise learning resource for beginner to intermediate level Vim users. It has more in common with cheatsheets than a typical text book. Topics like Regular Expressions and Macros have more detailed explanations and examples due to their complexity. I hope this guide would make it much easier for you to discover Vim features and learning resources than my own blundering experience.
