@prologic@twtxt.net it is from the generator. But in the actual go implementation methods are represented with a unsigned short. So 65k is the hard limit in go.

Oof.

@prologic@twtxt.net I get the worry of privacy. But I think there is some value in the data being collected. Do I think that Russ is up there scheming new ways to discover what packages you use in internal projects for targeting ads?? Probably not.

Go has always been driven by usage data. Look at modules. There was need for having repeatable builds so various package tool chains were made and evolved into what we have today. Generics took time and seeing pain points where they would provide value. They weren’t done just so it could be checked off on a box of features. Some languages seem to do that to the extreme.

Whenever changes are made to the language there are extensive searches across public modules for where the change might cause issues or could be improved with the change. The fs embed and strings.Cut come to mind.

I think its good that the language maintainers are using what metrics they have to guide where to focus time and energy. Some of the other languages could use it. So time and effort isn’t wasted in maintaining something that has little impact.

The economics of the “spying” are to improve the product and ecosystem. Is it “spying” when a municipality uses water usage metrics in neighborhoods to forecast need of new water projects? Or is it to discover your shower habits for nefarious reasons?

@prologic@twtxt.net the rm -rf is basically what go clean -modcache does.
I think you can use another form that will remove just the deps for a specific module. go clean -r

Any good ideas on how to maintain ~/go/pkg/mod and to remove old garbage?

@eldersnake@we.loveprivacy.club Several reasons:

• It’s another language to learn (SQL)
  
• It adds another dependency to your system
  
• It’s another failure mode (database blows up, scheme changes, indexs, etc)
  
• It increases security problems (now you have to worry about being SQL-safe)
  

And most of all, in my experience, it doesn’t actually solve any problems that a good key/value store can solve with good indexes and good data structures. I’m just no longer a fan, I used to use MySQL, SQLite, etc back in the day, these days, nope I wouldn’t even go anywhere near a database (for my own projects) if I can help it – It’s just another thing that can fail, another operational overhead.

@prologic@twtxt.net @movq@www.uninformativ.de this is the default behavior of pass on my machine:

I add a new password entry named example and then type pass example. The password I chose, “test”, is displayed in cleartext. This is very bad default behavior. I don’t know about the other clis you both mentioned but I’ll check them out.

The browser plugin browserpass does the same kind of thing, though I have already removed it and I’m not going to reinstall it to make a movie. Next to each credential there’s an icon to copy the username to the clipboard, an icon to copy the password to the clipboard, and then an icon to view details, which shows you everything, including the password, in cleartext. The screencap in the Chrome store is out of date; it doesn’t show the offending link to show all details, which I know is there because I literally installed it today and played with it.

I think boredom is a real force that pushes ourselves to the edge, to hopefully make a change in life, like going out to see real people. Social media creates this cozy, safe place to keep your mind occupied, letting life pass without realizing it. Social media may prevent users from reaping creative rewards of profound boredom | Hacker News

@prologic@twtxt.net see where its used maybe that can help.

This is an upsert. So I pass a streamID which is like a globally unique id for the object. And then see how the type of the parameter in the function is used to infer the generic type. In the function it will create a new *Info and populate it from the datastore to pass to the function. The func will do its modifications and if it returns a nil error it will commit the changes.

The PA type contract ensures that the type fulfills the Aggregate interface and is a pointer to type at compile time.

one that i think is pretty interesting is building up dependent constraints. see here.. it accepts a type but requires the use of a pointer to type.

Tutorial: Getting started with generics - The Go Programming Language – Okay @xuu@txt.sour.is I quite like Go’s generics now 🤣 After going through this myself I like the semantics and the syntax. I’m glad they did a lot of work on this to keep it simple to both understand and use (just like the rest of Go) 👌 #GoLang #Generics

ChatGPT is good, but it’s not that good 🤣 I asked it to write a program in Go that performs double ratcheting and well the code is total garbage 😅 – Its only as good as the inputs it was trained on 🤣 #OpenAI #GPT3

I started reading the proposal to introduce operator overloading in Go version 2 that I like to see: https://github.com/golang/go/issues/27605 Now a few hours later I ended up at this gem. Write a program that makes 2+2=5: https://codegolf.stackexchange.com/questions/28786/write-a-program-that-makes-2-2-5 There are some awesone solutions. :-)

Circling back to the IsPreferred method. A hasher can define its own IsPreferred method that will be called to check if the current hash meets the complexity requirements. This is good for updating the password hashes to be more secure over time.

func (p *Passwd) IsPreferred(hash string) bool {
	_, algo := p.getAlgo(hash)
	if algo != nil && algo == p.d {

		// if the algorithm defines its own check for preference.
		if ck, ok := algo.(interface{ IsPreferred(string) bool }); ok {
			return ck.IsPreferred(hash)
		}

		return true
	}
	return false
}

example: https://github.com/sour-is/go-passwd/blob/main/pkg/argon2/argon2.go#L104-L133

Hold up now, that example hash doesn’t have a $ prefix!

Well for this there is the option for a hash type to set itself as a fall through if a matching hash doesn’t exist. This is good for legacy password types that don’t follow the convention.

func (p *plainPasswd) ApplyPasswd(passwd *passwd.Passwd) {
	passwd.Register("plain", p)
	passwd.SetFallthrough(p)
}

https://github.com/sour-is/go-passwd/blob/main/passwd_test.go#L28-L31

Here is an example of usage:

func Example() {
	pass := "my_pass"
	hash := "my_pass"

	pwd := passwd.New(
		&unix.MD5{}, // first is preferred type.
		&plainPasswd{},
	)

	_, err := pwd.Passwd(pass, hash)
	if err != nil {
		fmt.Println("fail: ", err)
	}

	// Check if we want to update.
	if !pwd.IsPreferred(hash) {
		newHash, err := pwd.Passwd(pass, "")
		if err != nil {
			fmt.Println("fail: ", err)
		}

		fmt.Println("new hash:", newHash)
	}

	// Output:
	//  new hash: $1$81ed91e1131a3a5a50d8a68e8ef85fa0
}

This shows how one would set a preferred hashing type and if the current version of ones password is not the preferred type updates it to enhance the security of the hashed password when someone logs in.

https://github.com/sour-is/go-passwd/blob/main/passwd_test.go#L33-L59

I made a thing. Its a multi password type checker. Using the PHC string format we can identify a password hashing format from the prefix $name$ and then dispatch the hashing or checking to its specific format.

For some people they are just fun. Others can’t handle it. They go nuts. 2022-11-29T19:42:33-06:00 I prefer to spend my time writing code for only a few gopher users. No time for conspiracies.

ahh this is useful https://go.dev/doc/modules/managing-dependencies. the go culture doesn’t typically have large dependency graphs like Ruby or JS.

@prologic@twtxt.net the go get and go mod tidy wont fetch new changes. that’s all a manual affair AFAIK

I’ve started playing with Go today, just understood the basics and still a bit confused about the module and goroutine parts.

I’ll try to make something interesting soon.

@movq@uninformativ.de yeah.. i rewrote it a few times because i thought there was something breaking.. but was mistaken
though now i am seeing a weird cache corruption.. that seems to come and go.

Tell me you write go like javascript without telling me you write go like javascript:

import "runtime/debug"

var Commit = func() string {
  if info, ok := debug.ReadBuildInfo(); ok {
    for _, setting := range info.Settings {
      if setting.Key == "vcs.revision" {
        return setting.Value
      }
    }
  }

  return "" 
}()

@prologic@twtxt.net Alright, there’s some erroneous markdown parsing going on, I reckon. In my original twt I have a code block surrounded by three backticks. The code block itself contains a single backtick. However, at least for rendering, yarnd shows three backticks instead (not sure if my markdown is invalid, though):

Estoy empezando a programar Web en Go… Iré poniendo los ejemplos acá https://go.gemugami.com

it uses the queries you define for add/del/set/keys. which corrispond to something like INSERT INTO <table> (key, value) VALUES ($key, $value), DELETE ..., or UPDATE ...

the commands are issued by using the maddycli but not the running maddy daemon.

see https://maddy.email/reference/table/sql_query/

the best way to locate in source is anything that implements the MutableTable interface… https://github.com/foxcpp/maddy/blob/master/framework/module/table.go#L38

I was inclined to let this go so as not to stir anything up, but after some additional thought I’ve decided to call it out. This twt:

is exactly the kind of ad hominem garbage I came to expect from Twitter™, and I’m disappointed to see it replicated here. Rummaging through someone’s background trying to find a “gotcha” argument to take credibility away from what a person is saying, instead of engaging the ideas directly, is what trolls and bad faith actors do. That’s what the twt above does (falsely, I might add–what’s being claimed is untrue).

If you take issue with something I’ve said, you can mute me, unfollow me, ignore me, use TamperMonkey to turn all my twts into gibberish, engage the ideas directly, etc etc etc. There are plenty of options to make what I said go away. Reading through my links, reading about my organization’s CEO’s background, and trying to use that against me somehow (after misinterpreting it no less)? Besides being unacceptable in a rational discussion, and besides being completely ineffective in stopping me from expressing whatever it is you didn’t like, it’s creepy. Don’t do that.

@prologic@twtxt.net It’s called “cgod” and it isn’t written in C or Go? I want my money back…

I also like Gopher more than Gemini. The problem Gemini is trying to solve is better solved by just writing static HTML 4.01 pages.

@prologic@twtxt.net, business is slow (I also just got off that hyoo-män illness that is going around named COVID), so that leaves me some free time on my entrepreneurial hands. 😂 I have always lurked every couple of weeks or so. I see yarn has regressed on the UI! 😬😩

📣 NEW: Announcing the new and improved Yarns search engine and crawler! search.twtxt.net – Example search for “Hello World” Enjoy! 🤗 – @darch@neotxt.dk When you have this, this is what we need to work on in terms of improving the UI/UX. As a first step you should probably try to apply the same SimpleCSS to this codebase and go from there. – In the end (didn’t happen yet, time/effort) most of the code here in yarns will get reused directly into yarnd, except that I’ll use the bluge indexer instead.
