[go-nuts] Re: Refactor Asynchronous JS to Go

[Rusco]

Some time ago I compared Functional Reactive Programming FRP with Golang 
Channels (CSP), might be useful to you as a starter:

[go-nuts] Good recap of antivirus issue with Go binaries on windows

[Rusco]

Excellent article:
https://betterprogramming.pub/a-big-problem-in-go-that-no-one-talks-about-328cc3e71378
(The author tests against https://www.virustotal.com/gui/home/upload)  

Reddit thread:
https://www.reddit.com/r/golang/comments/y24was/an_article_about_go_hello_world_builds_mistakenly/

Even the problem is on the AV manufacturer side I wonder if we could get 
any help from the compiler developers  ?

[go-nuts] Re: App Engine hasn't upgraded beyond Go 1.16, which is now out of security window

[Rusco]

Googles own language on Googles own cloud lags behind several version,  I 
don't understand this :-( 

Microsoft seems to be more eager to keep things up to date: 
.NET 7 comes to Azure Functions & Visual Studio 2022 - .NET Blog

[go-nuts] Re: Golang and virustotal

[Rusco]

Regarding: "compile a simple helloworld main ...": 

My workaround is to insert a
  import "C"
among the other imports. It somehow alters the structure of the binary 
created and my av no more recognizes the binary. This is actually something 
which never happened when I am doing some Rust work.  

Might help.

[go-nuts] "Cortex XDR has blocked a malicious activity! " when running Go binary

[Rusco]

On Win10 I get this Antivirus message and can not get runnig my .exe on my 
company notebook. 

This is the binary, the only import is "fmt" : 
https://go.dev/play/p/GIUnvHMUJec?v=gotip

I checked antivirus diagnostics tools and found this:

https://www.virustotal.com/gui/file/01435f5f5fe574e8154a572094bd0dd21a6ce8bc506b9931be0e30a917fd68a1/detection
https://www.virustotal.com/gui/file/01435f5f5fe574e8154a572094bd0dd21a6ce8bc506b9931be0e30a917fd68a1/community
https://valhalla.nextron-systems.com/info/rule/SUSP_LazyDLL_Load_Golang_Jan20_1

So this is probably due to "suspicious LazyDLL loading in Golang binaries". 
Where is this Lazy DLL loading going on, in the runtime ? 
Is there a way to avoid this, to make it static for example ?

I wonder why there a not more complaints about antivirus blocking of Go 
binaries. 
I never came across such blocking in my Rust binaries. 


Any hints welcome
Rusco

afaik George Soros is behind the BLM Campaign, this alone justifies

Re: [go-nuts] Re: political fundraising on golang.org!

[Rusco]

After all (I think this has been discussed already ), who is owner of the 
Golang Project ? Isn't this supposed to be an open source / community based 
project ? 
What about mine political ideas, can I put them also on golang's front 
page, since I am part of the community ?

Where will we end up in some years if this continues, in middle age 
inquisition times with some new Jesuits popping up judging others for their 
political correctness ? 
Isn't Twitter and other social networks enough for articulating political 
opinions, or someone wants to force them upon us ?  

This is very bad smelling, I vote for leaving golangs' homepage neutral as 
for now ! Golang.org for golang.org, Twitter and other for politics.

[go-nuts] Re: Go wasm - package js - Set() fails for certain attributes

[Rusco]

If you try out your code in Javascript you can spot your error, it would be 
something like:

but.className = "somecssclass";
but.addEventListener("click", somefunction);


so for syscall/js (untested) something like:

var cb js.Callback cb = js.NewCallback(func(args []js.Value) { 
fmt.Println("Clicked") }) but.Set("className", "button42") 
but.Call("addEventListener", "click", cb)

[go-nuts] Question about fmt.Printf of maps

[Rusco]

I just tried this Google Playground recipe from Bradfritz:

https://play.golang.org/p/RYac90kI-H

(seen via https://github.com/golang/go/issues/21095)

and noted that y appears in the output but x appears as .

Can someone explain me why ? I was expecting that x appears in the same way 
like y.


package main

import (
"fmt"
"math"
)

var a, b int

func main() {
type S struct {
x int16
y float64
z interface{}
p *int
}
m := map[S]string{}
m[S{1, math.NaN(), "foo", }] = "x"
m[S{2, 3.0, , }] = "y"
for i := 0; i < 20; i++ {
fmt.Printf("%+v\n", m)
}
}

//output:

map[{x:2 y:3 z:0x1b5400 p:0x1b5404}:y {x:1 y:NaN z:foo p:0x1b5400}:]
map[{x:1 y:NaN z:foo p:0x1b5400}: {x:2 y:3 z:0x1b5400 p:0x1b5404}:y]
