Hello all,

After 2.5 years of writing, countless weekends and evenings, I released a book about the Go programming language.

The book is available for free on the website because I wanted to give something back to the developer's community :)

It is composed of 700+ pages, 41 chapters, and approximately 405 drawings/screenshots.

I tried to cover all the important topics that a new Go programmer should know.

At the end of each chapter, you can find a small Q/A and a bullet point list of key notions.

I would love to hear your feedback about it!

codegeek• 5 years ago

I love it. Hats off to you for your hard work on this. Who builds your illustrations/graphics ? Looks cool.

maximilienandi68• 5 years ago

My spouse :)

Thank you for your feedback !

jjice• 5 years ago

I really like that you go in detail of common and important standard library functions and hit come important things like database drivers and JSON. 700 pages is a nice big programming book and it looks like you're not skimping on details. Great job and good work!

maximilienandi68• 5 years ago

Hello jjice,

Thanks for those kind words, I tried to cover a lot of topics. Consequently it makes a lot of pages!

I hope that the content will help you ! Do not hesitate to contact me if you spotted an error or if you want to suggest an improvement.

120bits• 5 years ago

I can't thank you enough! I wanted to learn Go and wanted something like this. I really like the chapter structure, it really easy to follow and progress.

maximilienandi68• 5 years ago

Thank you very much, I really appreciate :) I hope that it will help you in your Go journey.

Do not hesitate to send me feedback in order for me to improve the content.

cosmodisk• 5 years ago

This is great,well done! I was thinking of picking Go at some point this year, need not to forget to buy the book. May I ask what did you for the website,looks pretty neat?

maximilienandi68• 5 years ago

Thank you for your feedback and support!

Go is easy to learn, and you need a limited amount of time to produce code!

I built the website with VueJS, and I use bootstrap for the CSS part (with https://bootstrap-vue.org/).

primitivesuave• 5 years ago

Thank you for this fantastic resource. I've been meaning to learn Go for a while, but have a lot of difficulty staying focused on tutorials with big blocks of text. Your concise bullet format is really easy to follow, and would be especially useful for anyone who doesn't speak English as their first language.

Also really respect that you clearly did this out of passion, so I'll say this to everyone on your behalf: support the author by purchasing a digital copy!

https://www.practical-go-lessons.com/buy-digital-or-hard-cop...

maximilienandi68• 5 years ago

oh thank you! I appreciate your kind words:) It's very rewarding to read all the comments on this thread... You made my day !

movedx4• 5 years ago

This looks amazing. Thank you.

I've found an error.

In Chapter 6, Section 3 (Introduction) you say, "In a previous chapter, we covered decimal and binary notation." but those topics aren't covered until Chapter 7 :)

maximilienandi68• 5 years ago

Thanks for spotting this, I will add it to my todo.

movedx4• 5 years ago

On another note, you might want to consider converting the online copy of the book to MkDocs (using the Material theme), so that it's easier to read, navigate and search.

I'd gladly lend a hand with this, if you like?

maximilienandi68• 5 years ago

I will take a look at it, thanks for your suggestion. I will check if Lyx has an option to export to this format.

evnix• 5 years ago

I like the current design, it is really clean and pleasant to read. I don't like Material Design, kind of makes everything look massive taking up too much space as if my desktop is a phone screen. for ex: http://angular-material.fusetheme.com/ui/forms

Could be that it's just me though

rustyboy2• 5 years ago

Can you help me understand this code on interfaces? If you were calling (CartStore.GetById()) where does (*cart.Cart) come from? I don't see any logical connection between these two.

  type Cart interface {
      GetById(ID string) (*cart.Cart, error)
      Put(cart *cart.Cart) (*cart.Cart, error)
  }

  // A type that implements the interface :

  type CartStore struct{}

  func (c *CartStore) GetById(ID string) (*cart.Cart, error) {
      // implement me
  }

  func (c *CartStore) Put(cart *cart.Cart) (\*cart.Cart, error){
      // implement me
  }

maximilienandi68• 5 years ago

Hello rustyboy, first thanks for your feedback.

I think that there is a mistake in the name of the interface type. It should not be `Cart` but something else. Like `CartStorage`.

A type that implement this CartStorage interface can be named `MySQLCartStorage` or `DynamoDBCartStorage`. Each database engine responsible for the storage will have a different implementation.

The interface is here to define a contract, a set of behaviors that you should implement.

I will definitely change that

bogomipz• 5 years ago

This looks great! It looks really well thought out and practical. Congrats on the release. Kudos and thanks for making it freely available as well. Cheers.

maximilienandi68• 5 years ago

Thank you bogomipz !

signal11• 5 years ago

A very minor point (sorry): please could you search-and-replace all “advices” to “advice” in the text? Advice is its own plural form.

maximilienandi68• 5 years ago

Thanks for your feedback added to my todo list !

maximilienandi68• 5 years ago

I just pushed a new release with that fix

msmagh• 5 years ago

Not a Go programmer and usually don't post here. Just wanted to appreciate the effort, also saving it for future reference. Thanks

maximilienandi68• 5 years ago

great ! see you soon

lamida• 5 years ago

Hi, Maximilien. I really like the structure of the books. It starts with "what we will learn" and ends with "test yourself" and key takeaways. The structure can help the reader to really conscious in understanding the learning goals and validating the understanding.

I also always want to write a programming language book or some other technical topic book in general, which the writing process will I use as learning process for myself. But I always wonder in deciding the topic to cover. How do you decide the topics to cover? Do you start from following existing books or online documentation topic sequences? Or just write whatever topic you are interested first and structure the content afterward?

maximilienandi68• 5 years ago

Thanks for your comment ! If you want to do it, just pick a language and start to write.

Writing is not easy but it becomes easier if you transform it into a habit.

In my experience I forced myself to write regularly like every day of the week. I usually worked one hour approximately by session.

By doing so you will see that you will achieve a lot.

Do not force youtself to write for one entire day then do nothing for a week.

Concerning the topics to cover I will recommand using a mind map to build the table of content. This is interesting because you can drag and drop sections easilly.

I would suggest first to define your targeted audience. Having this audience you can begin building the plan.

My approach was to teach notions progressively. Sometime I needed to rework the sections order. Use an editor that allow you to do that easilly like Lyx (love it).

Students generally love rituals and adding some introduction ritual/section and conclusion section is a plus.

Hope those recommendations will help you :)

Writing something is really a great way to make sure you understand something !

Good luck

noisy_boy• 5 years ago

I think this is very well structured. I really like the "Test yourself" section. As a person who finds small post-reading assignments enjoyable and motivating, my only suggestion would be to add a small assignment that employs the learnings. Actually coding what one just learned is arguably a good way to reinforce the learnings and raising further questions/doubts. E.g. for your Application Configuration chapter, an example assignment could be:

    Create a command line application that accepts users inputs as below:

        a. Mandatory "-firstName" flag to accept first name
        b. Mandatory "-lastName" flag to accept last name
        c. Optional "-middleName" flag to accept middle name
        d. Mandatory "-age" flag to accept age - only integers between 0 and 200 should be accepted
        e. Optional "-party" flag to accept political party following - only valid values are "D", "R" and "I"
        d. Optional "-userId" flag to specify user id - if HOME environment variable is set, extract user id from home directory path

rijoja• 5 years ago

Would you consider open sourcing the book? What systems are you using to create and maintain it?

maximilienandi68• 5 years ago

Hello rijoja, I'm currently thinking about it.

I'm writing the book with Lyx. Lyx documents are converted to LaTeX docs, then converted to HTML with pandoc. Then I have a homemade Go script that generates the VueJs components (one per chapter).

This question is asked a lot so I will write something about the system because it can help other writers.

Zababa• 5 years ago

Love the book! I think there's a small typo on https://www.practical-go-lessons.com/chap-41-cheatsheet, 2 Slices: "A good resource for playing with maps is https://github.com/golang/go/wiki/SliceTricks". I think you meant slices instead of maps?

fishywang• 5 years ago

One feedback: I skimmed through the Context chapter and noticed that you made the common mistake.

In the code snippet provided at https://www.practical-go-lessons.com/chap-37-context#the-ser..., you made the channel unbuffered. The doWork goroutine would write to the channel and the "main" goroutine would read from it. But since the "main" goroutine could exit early because of context cancellation, they could get into the case of no one on the reading end any more, causing the doWork goroutine to be blocked forever (the writing to the channel is blocked when there's no one to read it).

Someone even published a paper about fixing this common mistake in open source projects a few days ago: https://www.reddit.com/r/golang/comments/m66djp/automaticall...

alexeyshurygin• 5 years ago

Thank you for your work. I absolutely love the book. You might add links to buy digital copy at the very top of the page. Currently, I've found the link on 3rd attempt) Also, why not sell on Gumroad (https://gumroad.com)? It is convenient. Good luck!

damip• 5 years ago

Wow thank you for your work and providing it for free. Is there a way to submit correction PRs ? maybe a github ?

maximilienandi68• 5 years ago

I'm currently working on it :)

For the moment you can post your corrections on that URL : https://www.practical-go-lessons.com/feedback

ok_coo• 5 years ago

Thank you for this! We just started using Go for all of our new and/or updated backend stuff and I love it.

I'll definitely be checking this out. :)

maximilienandi68• 5 years ago

Thanks I appreciate :)

lovetocode• 5 years ago

I love this -- thank you!

maximilienandi68• 5 years ago

Thanks for your support!

wmu• 5 years ago

Looks great! Seems there were some issues in conversion into HTML chapter titles. For example https://www.practical-go-lessons.com/chap-31-logging#log.fat...

maximilienandi68• 5 years ago

Thanks for your feedback I will fix this :)

throwaway77384• 5 years ago

I applaud the effort. Very impressive work. I appreciate the free access to this, but will be buying, if / when I have time to work through some of the lessons :)

maximilienandi68• 5 years ago

Thanks for your feedback ! It makes me happy if it can help you !

kroolik• 5 years ago

The book looks very interesting! In the section about logging, Logrus is unfortunately in maintenance mode now. We've used it at my place, now we have switched to Zap.

maximilienandi68• 5 years ago

Thanks for your feedback ! I will add a warning in the book concerning Logrus.

I will also check Zap to add an example :)

mprovost• 5 years ago

Nice! What were the tools you used to write it and convert it to the ebook and paper versions?

maximilienandi68• 5 years ago

Thanks,

I worte the book using Lyx (https://www.lyx.org/) Each chapter is a Lyx document.

Then I converted : Lyx to LaTeX, then LaTeX doc are converted to HTML with pandoc (https://pandoc.org/).

Then I have an homemade script to generate Vue Components.

Lyx and Pandoc are great tools !

adeptima• 5 years ago

Hi maximilienandi, great work! Easy to read for non-native!

Always nice to see more alternative to the Blue Book too ;)

When I open Golang books or any kind of tutorials, I usually jump into Concurrency sections to see its depth and quality ...

If ever start thinking of selling v2 of your book, please go through Katherine Cox-Buday book "Concurrency in Go" content.

I like Katherine but your writing style is much much easy to read and process. Wish half of Katherine content will migrate into your future works.

Adding reference on Katherine book might help others too.

maximilienandi68• 5 years ago

Hi adeptima, thank you for your feedback!

I am really happy that you like the writing style.

I will order the book written by Katherine.

Concurrency is a really difficult topic; maybe I will add more content about it later. Real-world use-cases are hard to find also.

binaryorganic• 5 years ago

Always assume Go references are about the board game, always disappointed. Congrats on the book!

maximilienandi68• 5 years ago

Thank you very much !

RobKohr• 5 years ago

I was tricked too; maybe doubly so.

I thought this was a book on writing programs to play Go.

I feel at this point I should use this book to write a program to play Go using Go, and then in a way I wouldn't be so wrong.

tomca32• 5 years ago

This looks great! I absolutely love that it assumes no knowledge of anything, including how the computer works. This is how all educational material should be written.

I think that most knowledge gaps we all have are caused by a teacher/book making assumptions about what we already know.

maximilienandi68• 5 years ago

Hi tomca32,

Thank you for the feedback. I tried to make it accessible to new programmers. I hope it will be used by people how wants to start their programmer's journey.

Being a self-taught programmer, I always suffered from not knowing some very basic notions. I learned a lot in the process of writing those chapters.

dave_sid2• 5 years ago

Moby wrote a song about it in the 90s

ChrisMarshallNY2• 5 years ago

Excellent!

I am not a Go programmer, so I am not your target audience, but I have written a book, so I understand the work.

Thanks so much!

maximilienandi68• 5 years ago

Thank you ChrisMarshallNY, for your kind message. I hope you will start using Go in the future!

ChrisMarshallNY2• 5 years ago

I sent a link to a friend, who is very much a Go programmer (I am a Swift programmer).

insdel• 5 years ago

Looks very good! Thanks for providing it free.

maximilienandi68• 5 years ago

I hope it can help others in the process of learning how to build programs !

dctoedt2• 5 years ago

Looks great.

How'd you build the Web site — a package of some sort, or did you roll your own CSS? I've been working on a law-related book that I plan to post; I like the look of your site.

(I suppose it's too much to hope for that you created this with Emacs and org-mode — which is what I'm writing my book in — together with a nifty CSS package ....)

maximilienandi68• 5 years ago

Thanks !

I wrote it using Lyx which is WYSIWYG for LaTeX. Then I convert the LaTeX document into HTML.

The HTML is then injected (with some modifications) into a Vue component (the website is built with Vue).

I use only Bootstrap for the CSS (with bootstrap-vue). When I have some time I will publish the sources of my script.

I hope it can help you !

AnimalMuppet2• 5 years ago

I wrote it using Lyx which is WYSIWYG for LaTeX. Then I convert the LaTeX document into HTML.

What did you use to do the conversion? Will Lyx export HTML, or did you use something else?

jedberg• 5 years ago

which is WYSIWYG for LaTeX

Oh the delicious irony. Don't tell Donald Knuth! :)

perceptron001• 5 years ago

Great work. I am learning golang right now. The art/pics look amazing and the samples and the explanations are on point. Thank you for your work! I'm sure it will go a long way I'll made sure I tweet about it.

maximilienandi68• 5 years ago

Thank you for your support, I really appreciate, I hope many newcomers will find it interesting.

redisman• 5 years ago

Looks great. I’m getting to learn go in my new role so this will help me get up to speed before I start

maximilienandi68• 5 years ago

Hello redisman, I hope it will help you.

Do not hesitate to share your feedback with me, especially if something is difficult to understand or if you spotted a mistake :)

boundingpoodle• 5 years ago

Thank you for building this!

I appreciate chapter 40 being included, a quick summary of go/programming recommendations. Also the illustration on the landing page caught my eye, good choice.

maximilienandi68• 5 years ago

Many thanks! When I began writing Go code I found a lot of "Go idioms" on blog posts, it was hard to remember all of them. By the way, "Effective Go" (https://golang.org/doc/effective_go) is also a great summary of good practices.

exdsq• 5 years ago

This is excellent! Hope you get some sales to make up for the effort :)

maximilienandi68• 5 years ago

Thanks, I hope too !

arendtio• 5 years ago

I just scrolled through the chapter that looked most promising to me in the table of contents (Chapter 36: Profiling) and I have to say I love it!

On that one hand the basic steps are there like how to download a specific zip file, but at the same time it goes deep into the different types of profiling and how to use the mandatory tools.

maximilienandi68• 5 years ago

Thanks for your support arendtio ! I am happy that you liked this chapter, it took me a lot to write, because I never used pprof before. But it's a great tool.

Dentrax• 5 years ago

Excellent job! Maybe you are already thinking about it, but... You can add a Search Bar and Go version & language selection for the documentation. (i.e. see (bottom left): https://docs.godotengine.org/en/stable/)

Also I just published this on /r/golang if you do not mind. :)

maximilienandi68• 5 years ago

Thank you for those suggestions. Adding a search bar is already in my todo list. I will probably use Algolia.

Thank you for posting this on reddit ! I tried to do it but I made a mistake in the title, so I deleted the post and posted again (I never posted on reddit before). Now it seems that my second post is not really visible.

Thank you for your support Dentrax !

"This site is blocked due to a security threat that was discovered by the Cisco Umbrella security researchers."

Category: Malware

That is the warning I'm getting on this link at work. Of course I don't think you are trying to malware people, but might want to look into that on why people might not be able to access your site.

maximilienandi68• 5 years ago

Hello hodder, thanks for reporting this. I have no idea what is the cause of this...

maximilienandi68• 5 years ago

I ran a scan with Norton antivirus on the website artifacts downloaded on AWS the result is OK.

I also checked the website with Google safe browsing (https://transparencyreport.google.com/safe-browsing/search?u...) and the result is also OK. I also run the test with virus total website and no threats have been detected. (https://www.virustotal.com/en/#url).

If you have more information about this do not hesitate to share!

joelthelion• 5 years ago

Cisco is pretty terrible and has tons of false positives. I wouldn't worry too much.

pietroppeter• 5 years ago

I just love the positive vibes of this post, feedback received, and OP’s replies. It just makes HN a happier place!

maximilienandi68• 5 years ago

I also loved the experience of posting!I'm so happy to read messages of the community ! Thank you all !

itwy• 5 years ago

I love your writing style. Specially the way of not assuming previous knowledge.

maximilienandi68• 5 years ago

I tried to define every notions used. Thank you very much for liking my style. I hope that this book will help others to start programming with Go !

RSHEPP• 5 years ago

Learned something useful right away in the cheatsheet. Use table tests all the time, but never thought of the param struct for multiple function params.

Awesome work!

maximilienandi68• 5 years ago

The table test model provided in this chapter is an adaptation of the one automatically generated by Goland, i find it really cool to use ! If you have the IDE right click > Genenerate > Table test !

I plan to add more content to the cheatsheet in the future , so stay tuned :)

zealsham• 5 years ago

Whenever I encounter any book on go , the first thing I do is to read the installation page . This is the best I’ve seen of any book . You made the whole “PATH” thing that drives new go users mad and gave a thorough reason of why it’s needed .

maximilienandi68• 5 years ago

The first time I installed Go I also ran into installation problems. At this time I was on Ubuntu.

I'm happy that you appreciated my explanations.

Hope it will help somebody in the future

_kst_3• 5 years ago

I haven't taken a look at it yet. Can you summarize what it offers that Donovan & Kernighan's "The Go Programming Language" doesn't? (Sincere question, not being snarky.)

maximilienandi68• 5 years ago

Thanks for your question. "The Go Programming Language" is a well-written book. I have not read every line of it, so my answer might not be precise.

I will highlight some key aspects of my project:

I teach computer science in my free time in a small non-profit organization. Most of the students have no knowledge at all in the field. I wanted to write a book that anybody could use, not only to learn Go but also to learn how to code from the beginning.

I tried to explain every notion by imagining a student with no prior knowledge. I also added content about some key notions like encoding, some basic knowledge about what a computer is made of, what a pointer is ...

I also tried to keep a practical approach, with many examples. I also added a lot of drawings and screenshots. Images are sometimes more efficient than long explanations (this what I learned when I began to teach children).

Keep me updated if you have some time. I would love to hear your feedback ;)

_kst_3• 5 years ago

Thanks for replying. It doesn't sound like I'm your target audience. Best of luck.

zelphirkalt• 5 years ago

Can you share the non-profit organization name?

_kst_3• 5 years ago

I'm curious why my question is getting downvotes.

herpderperator• 5 years ago

Hello, this is a great resource! I noticed a typo on Chapter 8, 7.1, and thought I would report it: "If you are used to programming the first two develop the first two actions are common."

I think "the first two develop" was meant to be deleted here.

maximilienandi68• 5 years ago

Thanks for reporting that, added to my todo !

andrewnc• 5 years ago

Very cool! Great work :)

maximilienandi68• 5 years ago

Thanks andrewnc !

satysin2• 5 years ago

Obviously I haven't read much yet but skimming through it for 5 minutes I am impressed with what I see. Great work!

One thing I feel is missing, a PDF preview of a few pages so I can see how it looks in the digital edition. Not a huge deal so don't stress about it but I always like to preview ebooks for some reason. I may be alone here tho :)

Really though great work. I am especially impressed at the effort you put into getting a dev environment "up and running" on Windows, Linux and macOS.

maximilienandi68• 5 years ago

Thanks for your kind feedback _l4jh. You are not the only one to request a preview ! I will add it when I have some time.

I will include maybe the Table of Contents and a couple of chapters.

satysin2• 5 years ago

Sounds great to me! Can't go wrong with a nice looking preview ;)

Also I forgot to say I really appreciate you giving this away for free online. It is clear you put a tremendous amount of time and effort into making this.

hankchinaski• 5 years ago

impressive amount of content

maximilienandi68• 5 years ago

Thanks ! I still have some chapters not published, I will add them later :)

oolonthegreat• 5 years ago

looking good! I liked the fact that you took a holistic approach where you don't ONLY teach go but also things like anatomy of a computer, json/xml, http etc. My only concern is that the name "Practical Go Lessons" doesn't seem to capture this, but I don't know what else would you name it.

maximilienandi68• 5 years ago

Thanks for liking my approach !

Finding the title was a really hard task. I asked myself existential questions for a couple of days about it. I agree with you it's not perfect.

syndacks• 5 years ago

Hey there, this is really inspiring. I did something similar to what you described (writing on weekends while working) except I wrote a novel, not a tech book.

I have some feedback, 5.1 Garbage collection, you write "By chance, Go has a garbage collector." Was this really by chance? I don't know think so, it was by design! You even suggest this with your paragraph before explaining what GC is. Consider changing the word "chance" to something like "design" or another word that reflects the concerted choice by the Go authors.

If you find this helpful, let me know and I'd be happy to continue giving you any similar feedback.

maximilienandi68• 5 years ago

Hello syndacks, thanks for your feedback ! Do not hesitate to chat with me directly on the website ! I added a chatbox (on the bottom right corner).

wanghq• 5 years ago

Great work! I headed to the context chapter and learned something I was not certain. But regarding the linked list (https://www.practical-go-lessons.com/chap-37-context#linked-...), since a context can be parent of multiple contexts, I feel it's more like a tree structure.

maximilienandi68• 5 years ago

Hello wanghq, thanks for your feedback. I will take a look at this. It's added to my todo

PaulAnunda• 5 years ago

This is awesome. Thank you!

jhunter1016• 5 years ago

This is fantastic. I just learned the basics of Go by building an SDK for a friend’s REST API. I’ll tell you what, you want to learn a language, build a client SDK. You’ll hit so many crazy issues, you’ll be forced to learn how things work.

That said, I’ve got a long ways to go, and I’ve already plowed through six chapters of the book. Nice work!

maximilienandi68• 5 years ago

Thanks jhunter1016 ! This is so true, My first Go program (for work) was to build a web server and it was so intense :)

I'm happy that you like the book

replwoacause• 5 years ago

How very generous of you. I know what I’ll be doing for the next few weekends at least... Thank you!

maximilienandi68• 5 years ago

Thanks ! Don't hesitate to send me a message with the chatbox if you have any questions

rollulus• 5 years ago

Really impressive. I'm a full time Go coder now, and lately I feel that a lot mediocre tutorials are appearing. In the sense that they compare as fast food to a quality dinner. I skimmed through your book and found the things I wanted to see: how to test, error wrapping, proper use of interfaces, etc. Your book is quality food. Excellent job!

maximilienandi68• 5 years ago

Hi rollulus, I’m so grateful you liked the book :) Do not hesitate to share with me if you found an error or an improvement suggestion.

maximilienandi68• 5 years ago

Hello andreagrandi, sorry to hear that, can you access the website now ? It's hosted on AWS with Amplify, I did not received any alerts regarding that.

The only warning I got was a Free-Tier limit alert.

Hi! Thanks for your reply, I found the problem. I'm using NextDNS and it blocks the domain because it's been registered only a few days ago. I've added it to the allow list and now it works, thanks!

pknerd• 5 years ago

Awesome. I have done a bit of Go and released a few toy libs but this book makes me to do Go again.

I also plan to write a book about scraping in python and your way of release is more logical for ppl like me.

Like the other guy I also got stuck at TOC. I will use your mind map technique.

Could you open source book releasing tools?
