Thank you!

Current design pattern is the best. You'd love it if you ever try to debug you own or other's code. Everyone will follow the same style so there would be no problem to understand what the code does. The proposals are good when you're writing code to forget about maintaining it later.

Love your videos bro but pls consider using a TTS for voice overs. It gets hard to understand what youre saying at time. Much love.

Relevan question. Installing go code and the vscode. Vs bring Errors after 2nd day of use for not found build and go.mod just because. Had tried to path direct to locations but it just dont work.

Hey fireship!

golangdojo under construction :-/ no cheatsheets or source of functions

Thank you so much for your tutorial! It helps me understand the very basics of a web app in GoLang! 🙏

You didn't show code 🙄

miss you buddy ❤

file, err := os.Open('file') err ?=> { do_staff(); } or file, err := os.Open('file'); err ?=> do_stuff()

Which IDE are you using here ?

wtf 😂 0:12

something I've recently done was needing to create a certificate generation function that could accept both RSA keys and EC keys, I did it slightly differently where it could accept any type and if it didn't mach a supported type it would error out. Now I should be able to go back and make it more strongly typed thanks to Generics

Why are people using Go... use Rust if u really care that much about performance.... And its a way better language. Go is only slightly more performant than Java but Rust blows both of them out of the water...

best goroutine tutorial on youtube :D

your ssl is toast

Error handling is perfect as is. It is the reason why Go production software is so stable. You must do the tedious but very important job that other languages allow you to ignore.

Great Series man!!

I’ve seen a company migrate from Java to Go because Java was not performant enough. Turns out they had 20 JVMs each running on a separate node with 1cpu and around 500mb of heap size. I saw benchmarks showing that with less but more powerful VMs (multiple cores and increased heap size) the performance increase was astonishing. I do think Go is a great language but when you migrate Java application because of bad performance, chances are you’re not coding/configuring VMs efficiently. So yes having performant Java environments requires a little more than java -jar but is that really a bad thing? I personally love performance tuning and Java offers so many possibilities depending on your setup. If you’re building a new application, go with the stack you and your team are most comfortable with, don’t just go with the hype. If you have an existing application, look for potential optimizations before thinking about migrating to a whole new stack.

Vscode shit the bed for the third time when it comes to debugging golang apps. Idk why. It hung in there for a couple months. Maybe an update did it. Spend over 4 hours the last week trying to just debug... and nothing. Horribly infuriating. So I'm switching to Goland. Also, you helped me get into go. Now it's a huge passion for me. Thanks.

Thank you for such awesome playlist

hello from the future....this channel is the best!

Try g++ instead of gcc.

1:40 If you don't specify int32 or int64 -> it depends on the machine you are on 3:50 %T will print type of the variable

if err is a feature not a bug

(Switch to GoLand, baby) 5:30 Package-level variables are accessible from other files (global) 9:37 Let's not use "export", let's just use a Capital letter instead - Yeah, that's a great idea.

3:50 Zero values concept - if no expression is assigned, the default value gets assigned 8:58 *Pointers and &addresses

Thank you so much man!

Can anyone explain the range concept at 12:13 why It was giving a deadlock

This is a moot point since Quarkus can compile to native binary and won't be needing JVM to run, and would have the smallest of footprint and resources.

I can follow it all except what is the a...: in the Println?

I was told that at the company I was at in 2015, there was a meeting in which the higher ups mulled over firing all of the Java developers. The licensing, after Oracle acquired Java, was a huge problem. It invited in Oracle lawyers. Programmers picking Java were bringing in legal peril for the company. I was one of the "Java Developers". They bought our company, and fought the inclusion of the JVM the entire time. A lot got ported to C#.

Bookmarked, thanks brothers

Just FYI: If you're on linux, it doesn't allow ports less than 1024 for users unless you are on root. Use manual ports instead. Eg: ":8080"

Do you still remember your UA-cam password?

Go + Enums = PERFECT

It would be much great if you could accompany some of those points with benchmarks

i can't do complex numbers in vs code help me please it's showing complex package is in std

Why can´t I just do: func customError(err error, msg string) { if err != nil { fmt.Println(err, msg) } } Or put anything you want inside the if, ErroF, log. etc?

To the portuguese speakers: Você não precisa mudar a variável do arquivo para o tipo interface io.Writer . Você pode e deve utilizar o método write sob a variável ainda com o tipo os.file, pq essa variável também implementa a interface Writer. func main (){ file,_ := os.Create("file.txt") n, err := file.Write([]byte("hello")) fmt.Println(n,err) file.Close ( ) } Thanks professor, u doing great, love u way of teaching. lesgo.

I'm on Odin Project. Thanks for the channel.

Very good tutorial! Question - what if you want to make a lambda function that receives a completely unknown JSON and you want the lambda to extract various fields from the unkown json and the fields to extract are also unknown and are read from a configuration stored in a database? How would you do that in go? I had to do this for my work plus transforming the json according to a config script stored in the database. I did it in both nodejs and python. For extracting fields and transforming the json I used lodash for nodejs and pydash for python using the _.get() and _.set() methods. How can I do this in golang?

Thanks

A back-end developer that doesn't know SQL is a like a front-end developer that doesn't know CSS

High quality. Short and clear. Nice.

Go has no error handling. Just because ppl who use the language tend to follow an error handling convention doesn't mean the language supports error handling. If you don't agree, then every modern language has Go's error handling. In java you wrap your return values in objects that can have an error object inside them.

that intro

nice

15:05 shamelessly was so during my very last interview
