- Deep dive into Goroutines and Go concurrency to be able to take advantage of Go server-level constructs

Description

Go is the new systems programming language for Linux and Unix systems. It is also the language in which some of the most prominent cloud-level systems have been written, such as Docker. Where C programmers used to rule, Go programmers are in demand to write highly optimized systems programming code. Created by some of the original designers of C and Unix, Go expands the systems programmers toolkit and adds a mature, clear programming language. Traditional system applications become easier to write since pointers are not relevant and garbage collection has taken away the most problematic area for low-level systems code: memory management. This book opens up the world of high-performance Unix system applications to the beginning Go programmer. It does not get stuck on single systems or even system types, but tries to expand the original teachings from Unix system level programming to all types of servers, the cloud, and the web.

What you will learn

•Explore the Go language from the standpoint of a developer conversant with Unix, Linux, and so on

• Understand Goroutines, the lightweight threads used for systems and concurrent applications

• Learn how to translate Unix and Linux systems code in C to Golang code

• How to write fast and lightweight server code

• Dive into concurrency with Go

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.

This book is a must have on your library!Initially I had my reservations about Go and this book (as I am not a developer/programmer), but after the first few chapters I was completely overturned by it!The author, without wasting any time -this is a not a beginners book-, immediately jumps to the point and you can really start writing Go code from the very first chapters. And this comes from a sysadmin who somehow was afraid to write any Go code before.It only took a few chapters playing with the code examples to see that. The chapters were enlightening and while reading the book I had the feeling that it was written for someone like me. Overall, this is a book of great quality, that you will use it again as a reference in the future.

This is a very nice book for those who know basic programming and they want to learn systems programming but also for those who are programmers and they are interested in learning Go.There are many examples that help the understanding of basic Go concepts and the way that things are done in Go. It also explains the basics of Unix and system programming in Unix.

I really like Go. I am replacing C with it in most of my choices. The fact that it comes "batteries includes" and that it has endured the last 10 years helps. So I really needed a book that would allow me to view it more as a tool than just a language.This is such a book. This is a book where you already know some Go (i.e. you have read the tutorial that is available at gopl.io). But it is also a book that is not self-contained, in that if you do know know enough Go, you need to use your web browser a lot. For example to lookup more stuff about reflections. Or some other packages that get imported.It is clear that the author did not intend to write yet another introduction to Go. The target audience is people who armed with a terminal and an editor are more interested in tooling. Stuff that in the "old days" you would decide to write in C. Now here is a path to write them in Go. This is the great achievement of the book. You go through it section by section and if you have any significant systems programming experience with C, you feel the relevance: "I've done this in C before! So that's how you do it in Go". And it is not about C. Scripting in any of your language of choice can at times be done in Go also.If you do not have time pressure, the sections are small enough that you can work one or two of them per day. That would be a slow progress, but it would also be a 10 minute per day plan.To learn Go, I would go through and introduction to the language (among the numerous ones available), then work this book and finally keep the GoPL at bay for reference.There have been typos which I have submitted to the author of the book and I read it on O'Reilly's Safari

The book starts with a rather obtuse and scattershot introduction to Go. Not enough to actually learn Go programming so it isn't a tutorial but it isn't terribly useful.The book doesn't really start until getting into File and processes and then it ends to quickly with a web applications section that seems tacked on. It isn't that any of it is particularly bad but if it is going to be a "Systems Programming" book then it should focus on systems programming and not programming basics of pointers, structs, installation, version numbers and the like and swerve sharply later into setting up a web server with database back end.

Easy start but even tho the author included a lot of code and commands I had to google a lot in order to follow along with the examples. Maybe his compile command does work but because the book's formatting is off, I had to google for it. Plus, the author omits saying in the text what the following commands will do so he missed his chance to clarify things.
