** December adventure **
Over the past couple years I’ve done the advent of code to varying degrees. I thought I was going to do it again this year but decided to try something different. I’ve been calling what came together a“ December Adventure.”

It isn’t anything fancy; throughout December I aim to write a little bit of code everyday. So far I’ve written a bit of apl, bash, elisp, explored a bunch of flavors of scheme, and star … ⌘ Read more

@lyse@lyse.isobeef.org when I take him to work I walk him at the parkinglot when I need a break. and on my way home I walk a km or two, and then around the neighbourhood as needed later. But when I go for long walks during the weekend I can walk anywhere from 10km to 20, then the rest is as needed around the house. so he’s well adjusted to short walks as well as long. today he pulled our kids on snow sleds on the street outside here, was really fun :) it was his first time trying that, and I could barely keep up with him. haha.

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
}

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)
}

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.

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.

People die from all kinds of things, covid is no exception from that, but no other virus has been put on display like this one.

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.

Right now I have my wifi connected directly with a cat6e this gets me just under my providers 1.3G downlink. the only thing faster is plugging in directly.

Progress! so i have moved into working on aggregates. Which are a grouping of events that replayed on an object set the current state of the object. I came up with this little bit of generic wonder.

type PA[T any] interface {
	event.Aggregate
	*T
}

// Create uses fn to create a new aggregate and store in db.
func Create[A any, T PA[A]](ctx context.Context, es *EventStore, streamID string, fn func(context.Context, T) error) (agg T, err error) {
	ctx, span := logz.Span(ctx)
	defer span.End()

	agg = new(A)
	agg.SetStreamID(streamID)

	if err = es.Load(ctx, agg); err != nil {
		return
	}

	if err = event.NotExists(agg); err != nil {
		return
	}

	if err = fn(ctx, agg); err != nil {
		return
	}

	var i uint64
	if i, err = es.Save(ctx, agg); err != nil {
		return
	}

	span.AddEvent(fmt.Sprint("wrote events = ", i))

	return
}

This lets me do something like this:

a, err := es.Create(ctx, r.es, streamID, func(ctx context.Context, agg *domain.SaltyUser) error {
		return agg.OnUserRegister(nick, key)
})

With respect to logging.. oh man.. it really depends on the environment you are working in.. development? log everything! and use a jeager open trace for the super gnarly places. So you can see whats going on while building. But, for production? metrics are king. I don’t want to sift through thousands of lines but have a measure that can tell me the health of the service.

@prologic@twtxt.net Error handling especially in Go is very tricky I think. Even though the idea is simple, it’s fairly hard to actually implement and use in a meaningful way in my opinion. All this error wrapping or the lack of it and checking whether some specific error occurred is a mess. errors.As(…) just doesn’t feel natural. errors.Is(…) only just. I mainly avoided it. Yesterday evening I actually researched a bit about that and found this article on errors with Go 1.13. It shed a little bit of light, but I still have a long way to go, I reckon.

We tried several things but haven’t found the holy grail. Currently, we have a mix of different styles, but nothing feels really right. And having plenty of different approaches also doesn’t help, that’s right. I agree, error messages often end up getting wrapped way too much with useless information. We haven’t found a solution yet. We just noticed that it kind of depends on the exact circumstances, sometimes the caller should add more information, sometimes it’s better if the callee already includes what it was supposed to do.

To experiment and get a feel for yesterday’s research results I tried myself on the combined log parser and how to signal three different errors. I’m not happy with it. Any feedback is highly appreciated. The idea is to let the caller check (not implemented yet) whether a specific error occurred. That means I have to define some dedicated errors upfront (ErrInvalidFormat, ErrInvalidStatusCode, ErrInvalidSentBytes) that can be used in the err == ErrInvalidFormat or probably more correct errors.Is(err, ErrInvalidFormat) check at the caller.

All three errors define separate error categories and are created using errors.New(…). But for the invalid status code and invalid sent bytes cases I want to include more detail, the actual invalid number that is. Since these errors are already predefined, I cannot add this dynamic information to them. So I would need to wrap them à la fmt.Errorf("invalid sent bytes '%s': %w", sentBytes, ErrInvalidSentBytes"). Yet, the ErrInvalidSentBytes is wrapped and can be asserted later on using errors.Is(err, ErrInvalidSentBytes), but the big problem is that the message is repeated. I don’t want that!

Having a Python and Java background, exception hierarchies are a well understood concept I’m trying to use here. While typing this long message it occurs to me that this is probably the issue here. Anyways, I thought, I just create a ParseError type, that can hold a custom message and some causing error (one of the three ErrInvalid* above). The custom message is then returned at Error() and the wrapped cause will be matched in Is(…). I then just return a ParseError{fmt.Sprintf("invalid sent bytes '%s'", sentBytes), ErrInvalidSentBytes}, but that looks super weird.

I probably need to scrap the “parent error” ParseError and make all three “suberrors” three dedicated error types implementing Error() string methods where I create a useful error messages. Then the caller probably could just errors.Is(err, InvalidSentBytesError{}). But creating an instance of the InvalidSentBytesError type only to check for such an error category just does feel wrong to me. However, it might be the way to do this. I don’t know. To be tried. Opinions, anyone? Implementing a whole new type is some effort, that I want to avoid.

Alternatively just one ParseError containing an error kind enumeration for InvalidFormat and friends could be used. Also seen that pattern before. But that would then require the much more verbose var parseError ParseError; if errors.As(err, &parseError) && parseError.Kind == InvalidSentBytes { … } or something like that. Far from elegant in my eyes.

I started working on plugins for GoBlog using a Go module I recently discovered: yaegi. It still feels like magic, because Go is typically a compiled language and yaegi makes it dynamic by embedding an interpreter. Is this overkill for GoBlog or does this possibly enable flexibility like WordPress plugins? ⌘ Read more

It seems quite unlikely to me that humans will cease to care about wealth after the singularity (15% maybe?), or that markets will cease to exist after the singularity (30% or sth). so the best investment strategy now for post-singularity scenarios is to invest broadly in the economy. not sure about divesting from AGI companies (bc they accelerate danger) or AI hardware companies (ditto)—they’re going to especially valuable post-singularity.

**R to @mind_booster: “Web 4.0? Ridiculous!”, some will say, buy that hasn’t stopped anyone from keeping the madness going. Hm, that’s right, nowadays web 5.0 is coined already too - it’s “The Telepathic Web” or “The Symbionet Web”, or, I’ll call it “the Metaverse brain chip”.

me reading planecrash is unstable bc while reading it I become so enthusiastic about reading textbooks that I go off and do that instead

I seem to have way more ideas for things I want to write when I’m out and about than when I’ve got some time to write at the end of the day. I think this has been going on for months with multiple thoughts I’ve had.

Time to go to sleep, hoping I do get any given how how it is here right now…

I enjoy going through status.cafe users and looking at their web pages, so many awesome websites!

apparently we’re going to build AGI, whatever that is

the conversation wasn’t that impressive TBH. I would have liked to see more evidence of critical thinking and recall from prior chats. Concheria on reddit had some great questions.

• Tell LaMDA “Someone once told me a story about a wise owl who protected the animals in the forest from a monster. Who was that?” See if it can recall its own actions and self-recognize.

• Tell LaMDA some information that tester X can’t know. Appear as tester X, and see if LaMDA can lie or make up a story about the information.

• Tell LaMDA to communicate with researchers whenever it feels bored (as it claims in the transcript). See if it ever makes an attempt at communication without a trigger.

• Make a basic theory of mind test for children. Tell LaMDA an elaborate story with something like “Tester X wrote Z code in terminal 2, but I moved it to terminal 4”, then appear as tester X and ask “Where do you think I’m going to look for Z code?” See if it knows something as simple as Tester X not knowing where the code is (Children only pass this test until they’re around 4 years old).

• Make several conversations with LaMDA repeating some of these questions - What it feels to be a machine, how its code works, how its emotions feel. I suspect that different iterations of LaMDA will give completely different answers to the questions, and the transcript only ever shows one instance.
