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.

This book starts with good coverage of Linux, the kernel, memory, scheduling mechanisms, and filesystem operations. After those first necessary chapters, C++ is covered in depth. Some of the topics include great depth on the object model, how to handle errors, and concurrency.The level of detail in this book is truly impressive. For example, the section on handling time in Linux using C++ serves as a great reference. The C++ memory model is also covered. I believe that both novice and experienced developers can benefit from this book.Bravo!

The chapters are well-structured, making it easy to follow along and build your expertise gradually. From process management and file systems to error handling and memory management, the book covers a wide range of topics crucial for Linux system programming. The authors' ability to merge advanced C++, system programming, Linux insights, and architecture into a coherent and accessible guide is commendable. The focus on boosting code quality through system programming techniques, refining, and optimizing their codebase is truly commendable.

Too many help books out there offer a title and then wander all over the map. This one is direct and focused on the topic. If you use Linux (who doesn't?) and you want to do your dev in C++ (not me, but a helpful reference), use this book to advance your learning. The book explains the strengths of Linux, and the intricacies of C++ and then how to make the various pieces work effectively together. I can't think of a current reason to run these items together, but we all know that customers have weird requests. If you need a specific reference for these things (C++ on Linux), this is a great option.
