Got contacted on instagram from someone who wanted to buy some of my images (NFT), I have been putting the images I liked the most into a collection (and add new ones when I take Images I think is good enough) into the collection. Just letting it sit there to see if I can make a sale one day.
Not sure yet if the person is serious or not - but If I could make a sale - then I’m all for it.
It’s much easier to put things up for sale as NFT then other ways.
I sell them as a 1 item thing. And put a price that I think is fair (Fixed price on all, but based on the amount of time I actually spend getting to all these locations).
One thing I have not liked about NFT is all the crap art stuff that there that takes 0 effort, but I do at least spend time picking out where we go. And each image has a memory attached to it, a trip with my family to that exact place..

I’m curious. How many people truly believe blockchain social networks are the future?

NFTs, tokens, monetization, revenue…

I’m sorry, but how are your random social media blabbers worth any money?
Unless you’re Shakespeare or Einstein or some philosophical or scientific genius, I don’t see why anyone would want to read your posts, let alone cash out some “crypto” from some “wallet”.

And that applies to most people. Sure, your lifestyle and your thoughts may be interesting. But who’s going to start paying to view what’s going on in your life?

As if likes, upvotes, hearts, and subscriptions weren’t narcissistic enough, let’s make people think someone wants to pay them with crypto to view their random posts online.

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.

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 {

})

@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’m trying to switch from Konversation to irssi. Let’s see how that goes. Any irssiers out there who can recommend specific settings or scripts? I already got myself trackbar.pl and nickcolor.pl as super-essentials. Also trying window_switcher.pl. Somehow my custom binds for Ctrl+1/2/3/etc. to switch to window 1/2/3/etc. doesn’t do anything: { key = "^1"; id = "change_window"; data = "1"; } (I cannot use the default with Alt as this is handled by my window manager). Currently, I’m just cycling with Ctrl+N/P. Other things to solve in the near future:

• better, more colorful and compact theme (just removed clock from statusbar so far)
  
• getting bell/urgency hints working on arriving messages
  
• nicer tabs in status bar, maybe even just channel names and no indexes
  
• decluster status bar with user and channel modes (I never cared about those in the last decade)
