That is Awe......Some, bro. Clean, no BS, StraightForward.

14:28 - so you're telling me I would have to write ALL THAT just to do a DIVISION? What is the point of being a bagillion times faster if it takes me 50x more time to write than a simple bash function?

Awesome video. This is the format I am looking for. Unfortunately it is hard to find this one in the flood of BS videos full of hours of void. Thanks for that!

Amazing tutorial, perfect, no fuss. This is what I was looking for. Good job mate!

great!

New sub here

Just finished your Go crash course and was looking for tutorials on how to build an api with no frameworks or external libs, which ended on me finding you again. Keep doing this great work man!

boss level neovim user

Thanks a lot of your great content! Please go on!

Oh, this is too good! Only small comment to 8:09 - the Header in my test ended with '=' char which got encoded to %3D. So it was mismatching with CSRF token stored in the DB (as it had =). After changing line 24 to _csrf, _ := url.QueryUnescape(r.Header.Get("X-CSRF-Token"))_ it finally worked. Many thanks again!

The video is only an hour long but I've been watching and replicating for hours

What theme in vscode are you using?

This video is amazing. It's perfectly tailored for programmers switching from a lang to golang. Your explanation and visuals are perfect, and also you don't run when explaning which is amazing.

It might be the cleanest and best Go context explanation video on KZbin.

Which vim plulgin do you use for Go ?

Absolute beauty….one of the best tutorials in the whole of internet , in any topic!!!! It’s everything you need to know about go. I went slowly and practiced every thing being discussed the video, took me good 6 hours, but I feel much confident in go….Great effin job sire ☘️

you are a go goat.....Love to learn from you ...Keep going dude

THE BEST VIDEO......GOAT

Damn, i really thought id like this language. If you're ethos is simplicity then you indent, you don't curly. Ok, that's a personal preference, it's not a showstopper. You didn't have a print function... You literally had to import it and with a weird package name. That's not simple. I'll pass.

Damn!!!! This was crazy good dude. Hats off for making it so simple

I want to know what is dumped to trash, include this rather than exclude this.

man you're a savior. That's the best tutorial i've ever seen in my whole life omg.

Alternate title: "Edging with Go for 1 hour". Jokes aside your teaching style is superb, no BS, no going in loops, straight to the point, and fun! Subscriber++

what a wonderful overview. i got a lot by watching this.

Coming from C, I'm loving Go! Many similarities, but the simplified syntax and control flow is so nice. Plus, if one wants, you can do all the unsafe pointer arithmetic and operations from C in Go too! Looking forward to coding more Go and enjoy your concise video on learning it. Using Neovim is a nice plus, too!

Very useful

at 44:13 we need to lock the memory from other processes, not lock the process itself

Dude you're a lifesaver. Thanks for the incredible short & efficient course.

I am loving this video!

Man this tutorial is spot on. Not 1 hour learning about ifs and while. Covers a lot, in a pragmatic and concise way. Please make a tutorial on Gorm if you have the chance. Thank you, very much and keep up the good working :)

This really GOes fast! Nice

I tried putting a variable without defining if it is a string, float, integer...

Is the syntac for, var intSlice3 []int32 = make(int32[], 3, 8) is correct? Coz getting an error like this expected operand, found ']' But mentioning type of elements for slice after [] is working for me, Like var intSlice3 []int32 = make([]int32, 3, 8)

this is the best go tutorial i had come across. short and precise no time waste

Wich text editor is that?

Thank you, this was easy to understand.

I absolutely love videos like this, straight to the point no non-sense.

Hi sir is there a way to contact you, any mail id or something.

This is a great video, very informative well done. It's a shame there was so much dust floating around during the video though - made it hard on these old eyes lol. Seriously though, awesome information!

Lonly

late to the party but is that CointBalance Params or CoinBalanceParams at 57:41

Best video on Go!!!

What a legend. Awesome videos!

Great

Быстро говорите. Непонятно ничего!!!

This is one of the simplest video on context, thank you so much

This is such a nice, tight format for more experienced developers who just need a quick overview/refresher. There’s a lack of intermediate-knowledge resources like this so Thank you :)
