(1) You go to the store and buy a microwave pizza. You go home, put it in the microwave, heat it up. Maybe it’s not quite the way you like it, so you put some red pepper on it, maybe some oregano.

Are you a pizza chef? No. Do we know what your cooking is like? Also no.

(2) You create a prompt for StableDiffusion to make a picture of an elephant. What pops out isn’t quite to your liking. You adjust the prompt, tweak it a bunch, till the elephant looks pretty cool.

Are you an artist? No. Do we know what your art is like? Also no.

The elephant is “fake art” in a similar sense to how a microwave pizza is “fake pizza”. That’s what I meant by that word. The microwave pizza is a sort of “simulation of pizza”, in this sense. The generated elephant picture is a simulation of art, in a similar sense, though it’s even worse than that and is probably more of a simulacrum of art since you can’t “consume” an AI-generated image the way you “consume” art.

@prologic@twtxt.net yeah. I’d add “Big Data” to that hype list, and I’m sure there are a bunch more that I’m forgetting.

On the topic of a GPU cluster, the optimal design is going to depend a lot on what workloads you intend to run on it. The weakest link in these things is the data transfer rate, but that won’t matter too much for compute-heavy workloads. If your workloads are going to involve a lot of data, though, you’d be better off with a smaller number of high-VRAM cards than with a larger number of interconnected cards. I guess that’s hardware engineering 101 stuff, but still…

On LinkedIn I see a lot of posts aimed at software developers along the lines of “If you’re not using these AI tools (X,Y,Z) you’re going to be left behind.”

Two things about that:

1. No you’re not. If you have good soft skills (good communication, show up on time, general time management) then you’re already in excellent shape. No AI can do that stuff, and for that alone no AI can replace people
   
2. This rhetoric is coming directly from the billionaires who are laying off tech people by the 100s of thousands as part of the class war they’ve been conducting against all working people since the 1940s. They want you to believe that you have to scramble and claw over one another to learn the “AI” that they’re forcing onto the world, so that you stop honing the skills that matter (see #1) and are easier to obsolete later. Don’t fall for it. It’s far from clear how this will shake out once governments get off their asses and start regulating this stuff, by the way–most of these “AI” tools are blatantly breaking copyright and other IP laws, and some day that’ll catch up with them.
   

That said, it is helpful to know thy enemy.

I played around with parsers. This time I experimented with parser combinators for twt message text tokenization. Basically, extract mentions, subjects, URLs, media and regular text. It’s kinda nice, although my solution is not completely elegant, I have to say. Especially my communication protocol between different steps for intermediate results is really ugly. Not sure about performance, I reckon a hand-written state machine parser would be quite a bit faster. I need to write a second parser and then benchmark them.

lexer.go and newparser.go resemble the parser combinators: https://git.isobeef.org/lyse/tt2/-/commit/4d481acad0213771fe5804917576388f51c340c0 It’s far from finished yet.

The first attempt in parser.go doesn’t work as my backtracking is not accounted for, I noticed only later, that I have to do that. With twt message texts there is no real error in parsing. Just regular text as a “fallback”. So it works a bit differently than parsing a real language. No error reporting required, except maybe for debugging. My goal was to port my Python code as closely as possible. But then the runes in the string gave me a bit of a headache, so I thought I just build myself a nice reader abstraction. When I noticed the missing backtracking, I then decided to give parser combinators a try instead of improving on my look ahead reader. It only later occurred to me, that I could have just used a rune slice instead of a string. With that, porting the Python code should have been straightforward.

Yeah, all this doesn’t probably make sense, unless you look at the code. And even then, you have to learn the ropes a bit. Sorry for the noise. :-)

@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.

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.

      if setting.Key == "vcs.revision" {
        return setting.Value
      }
    }
  }
