Where can I send feedback about an Early Access title?

If you have any feedback about the product you're reading, or Early Access in general, then please fill out a contact form here and we'll make sure the feedback gets to the right team.

Can I download the code files for Early Access titles?

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date?

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready?

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.

I am a Packt subscriber, do I get Early Access?

Yes, all Early Access content is fully available through your subscription. You will need to have a paid for or active trial subscription in order to access all titles.

How is Early Access delivered?

Early Access is currently only available as a PDF or through our online reader. As we make changes or add new chapters, the files in your Packt account will be updated so you can download them again or view them online immediately.

How do I buy Early Access content?

Early Access is a way of us getting our content to you quicker, but the method of buying the Early Access course is still the same. Just find the course you want to buy, go through the check-out steps, and you’ll get a confirmation email from us with information and a link to the relevant Early Access courses.

What is Early Access?

Keeping up to date with the latest technology is difficult; new versions, new frameworks, new techniques. This feature gives you a head-start to our content, as it's being created. With Early Access you'll receive each chapter as it's written, and get regular updates throughout the product's development, as well as the final course as soon as it's ready.We created Early Access as a means of giving you the information you need, as soon as it's available. As we go through the process of developing a course, 99% of it can be ready but we can't publish until that last 1% falls in to place. Early Access helps to unlock the potential of our content early, to help you start your learning when you need it most. You not only get access to every chapter as it's delivered, edited, and updated, but you'll also get the finalized, DRM-free product to download in any format you want when it's published. As a member of Packt, you'll also be eligible for our exclusive offers, including a free course every day, and discounts on new and popular titles.

Its clear structure, starting from basics to advanced topics, ensures a smooth learning curve.The chapters on concurrency and network programming are particularly valuable, addressing critical areas in modern development. The author's passion for Go and insightful tips on idiomatic practices have significantly influenced how I write code.Overall, this book is well-written, comprehensive, and full of practical wisdom. It has expanded my technical skills and enthusiasm for Go. Highly recommended!

System Programming in Go offers a practical exploration of system programming using a language often neglected in the systems domain. When one thinks of System Programming, go is probably not the first language that comes to mind. Go's concurrency features, garbage collection (as well as other features) make it ideal for applications such as backend web development. Even as a relatively experienced go developer I benefited greatly from this book.

System Programming Essentials with Go” is a gem for anyone diving into Go. As a software engineer with a background in C++ and Java, I found this book to be a refreshing and enlightening read. The author does an excellent job of explaining complex concepts in a clear and straightforward manner, which really resonates with my preference for a strong foundation of knowledge before coding.The practical examples and hands-on exercises are fantastic. They made me feel more confident in applying what I’ve learned to real-world system programming tasks. I also loved how the book delves into Go’s philosophy and idiomatic practices, deepening my appreciation and understanding of the language.This book has significantly enhanced my programming skills, and I highly recommend it to both experienced developers and beginners eager to learn system programming with Go.
