Hello I don't get it

Nİce very nice I loving it

Nice I like the video

Can I post a open Golang job here?

Thank you for this.

Would you like to help out?

hello all - glad to join GolangNews!

Certainly useful. Thanks

That should definitely help with performance!

I found this article while trying to implement quicksort, super interesting!

// try to avoid this pattern

What to avoid, why to avoid? No explanation at all! In the end it's perfectly fine to ask for environment variables. Just don't do it every time.

I guess @jot thinks os.Getenv is called all the time here and she/he could be right.

Or @jot is talking about something completely different, nobody knows.

Saying to avoid something without explanation isn't very helpful. All I could do was guessing.

Very nice. stdlib, one of those strong features Go is built upon. But please do not use these kind of snippets in code:

if os.Getenv('ENV') == "prod" // try to avoid this pattern

Even in examples. People tend to use what they see, especially in well written articles such as yours.

Ok but godotenv is already able to do that. It can be used as a library and an executable godotenv -f /some/path/to/.env some_command with some args". I missed something ?

EDIT: Ok I understand the use case. It's to export vars from an env file. Sorry, I missed the point :)

Hello how do I get registered, want to post a blog link of mine (using go) https://blog.rutjes.dev/2022/04/cloud-cost-savings-using-hybrid_15.html

Would love to submit a blog : https://blog.rutjes.dev/2022/04/cloud-cost-savings-using-hybrid_15.html

Hi all

Best library to read xlsx in go. Too bad there is no equivalent to read xls

This is a really helpful go lib.

This looks great! Thanks for posting. 

good stuff

Really nice post. We are thankful to you for sharing it.

Thank You For Sharing.

In some case, customizing GC is nice.

Easy with JVM, not possible with Go.

Example: do not free memory in serverless function, in order to prevent GC pause.

Very nice to see Fuzz testing in the standard library.

No more third party tools needed! \o/

Looking for a benchmark for generics vs reflection !

This talk by Yehonathan Sharvit is about the principles of Data-Oriented programming and how to reduce the complexity of software. As the talk is not focused on Go, the video is an interactive session between our speaker and the #gofrm community.

Data-Oriented programming is a paradigm that aims at reducing the complexity of software systems and making the development experience more productive. Data-Oriented programming draws a clear separation between code and data. It treats data as a value that is manipulated by general-purpose functions. In this talk, we illustrate the principles of Data-Oriented programming in the context of a software production system. After attending this talk, you will be able to apply Data-Oriented programming principles in your preferred programming language, whether it's Object-Oriented or Functional, and reduce the complexity of the systems you build.

➡️ Yehonathan Sharvit ⬅️ (https://twitter.com/viebel) has been working as a software engineer since 2000, programming with C++, Java, Ruby, JavaScript, Clojure and ClojureScript. He currently works as a software architect at Cycognito, building software infrastructures for high scale data pipelines. He shares insights about software at https://blog.klipse.tech/, he writes technical books, he speaks at conferences and leads Clojure workshops around the world. He is the author of Data-Oriented programming, published by Manning. Yehonathan is passionate about making interesting things easy to understand.

14:10 What makes a software system complex?

17:36 Principle #1: Separate Code from Data

27:55 Principle #2: Represent Data with generic data structures

58:40 DOP challenge

A small copy-paste typo can be found at end of slide §6.1 Generic Keys and Values functions from x/exp/maps.

Values was mistyped Keys:

for i := 0; i < 5; i++ {

fmt.Printf("Values: %#v\n", Values(m))

}

Good catch ! Fixed, thank you.

super cool

awesome

Not strictly go related but I thought it was really interesting. 

Hey, first time commenting here

awesome

Searching for a ways to integrate Go WASM with Cloudflare workers. Maybe you have some ideas or start points?

Wasmer works well, but i never tried with Cloudflare workers

Sorry for the late reply, I didn't get any notification about your comment.

No, I have never worked with WASM or Cloudflare, sorry :/

Valuable information for golang developers

niice

Also of interest https://mobile.twitter.com/FiloSottile/status/1455260886910783501

Interesting project. Can't wait to see what it will look like in a few months

Nice

Not sure I agree with most of this, but it's interesting to see another's approach to dealing with complexity.

The article correctly identifies complexity as the biggest problem with writing complex long-lived web applications, but then presents a series of ad-hoc solutions to specific problems (problems caused by the structure they have chosen) as the best answer. It would probably be better titled 'Things I learned writing go' or something similar, rather than attempting to frame different decisions trade/offs as anti-patterns.

To take one example, having one user model is good in that it is easier to maintain and less complex to think about, but the author advocates having a write model and an api model - in some circumstances that might be useful (where there are many private fields which must never leak to the view or require processing before presentation), but most of the time it's overkill and needless complexity.

Super cool, these guys make great articles about making clean web applications in Go

404 I think this is the new url https://git.mills.io/prologic/fbox

amazing!

agree! I used it in my project go-stash, and it's much faster than encoding/json.

Is that ok for remote from China?

US and Canada only unfortunately. 

what's advantages over x/ratelimit?

I've used it for a while, it's awesome!

I'm wondering how to get points.

As of today TinyGo supports more than 60 different boards!

Also the list of supported devices in the drivers repository is fast growing. Find them here: https://github.com/tinygo-org/drivers

Thanks for sharing. Is the build caching behavior still the same today?

Nicely explained.

Most important takeaways (for me) are: Use table driven tests AND use interfaces, so you can mock stuff :)

Nicely explained! This also had some new insights for me, even though i'm working with go for some years now :)

This has been retracted because they compared different versions of their code so the binary comparisons were wrong. link to a breakdown here

A truly practical approach to learning Go

Interesting

Really cool.

A great deep dive into the internals. Thanks for sharing :)

Thanks. 

nice - didn't know about this - i am using bigcache https://github.com/allegro/bigcache as drop in replacement instead of redis in my go app - i shall give this a try

Hi, How one can earn some points to be able to post interesting golang project?

Nice tool.

It is relevant to Israel? We have now a Tesla sales office here.

Great video!

This has been one of the most frustrating things about developing Go network code. IP addresses are a mess. This is interesting.

Yes and written by some of the people involved in the original net package. Brad used to be one of the maintainers of net/http and net packages in go. I'm glad they are so conservative about changing the standard library though, even if it does mean warts like this persist.  

I've edited the title to the one from the repo to make this more descriptive. 

Looks good!

Thanks for sharing.

Very well and helpful. Thanks

Very well and helpful. Thanks

Go 1.16 (which is in RC this month) does embedding natively.

A nice article.

In one word: spam. The article is absolutely not related with Golang or Go developers.

Agreed, flagged a little late I'm afraid

The tricky bit here is picking the right abstractions, there's nothing worse than the wrong abstraction that would take too much work to remove. 

Thanks for posting, this looks really interesting. The main problem I suppose would be deliverability, so you'd have to set up reverse DNS, SPF etc. use a rented server, and perhaps warm up the ip for a while. 

Crazy!

It does look significantly faster on most benchmarks, and apparently the crypto has a lot of hand-rolled assembly for x86. 

A great article! All the pieces put together making a good introduction to DDD in golang
