📣 Outage Notification: On Tuesday 23rd May 2023 between 7.30am to 5pm, there will be an outage of undefined length with no known start time due to planned power meter upgrades on the premises by the energy company.

You know, it’s one of those things where they give you a ~12hr window 🤦‍♂️ I will post here again once the technician is on-site and power down. I will power back up as soon as the work is complete.

According to the information I’ve received, the outage should be no more than ~1-2hrs.

Apologies for any inconvenience 🤗

Still undecided between TiddlyWiki, DokuWiki, Bear, Benotes, Memos, my blog software, standardnotes, apple notes and more. I like them all quite a bit, but standardnotes, the only one that has reall multiplatform is so fucking complicated to host on your own and then they have this stupid offline subscription thing that allows rich text or the block editor that works like notion. I also found codex docs which is really really nice. Unfortunately they lack proper authentication. 1 / 2

@stigatle@yarn.stigatle.no @prologic@twtxt.net @eldersnake@we.loveprivacy.club I love VR too, and I wonder a lot whether it can help people with accessibility challenges, like low vision.

But Meta’s approach from the beginning almost seemed like a joke? My first thought was “are they trolling us?” There’s open source metaverse software like Vircadia that looks better than Meta’s demos (avatars have legs in Vircadia, ffs) and can already do virtual co-working. Vircadia developers hold their meetings within Vircadia, and there are virtual whiteboards and walls where you can run video feeds, calendars and web browsers. What is Meta spending all that money doing, if their visuals look so weak, and their co-working affordances aren’t there?

On top of that, Meta didn’t seem to put any kind of effort into moderating the content. There are already stories of bad things happening in Horizon Worlds, like gangs forming and harassing people off of it. Imagine what that’d look like if 1 billion people were using it the way Meta says they want.

Then, there are plenty of technical challenges left, like people feeling motion sickness or disoriented after using a headset for a long period of time. I haven’t heard announcements from Meta that they’re working on these or have made any advances in these.

All around, it never sounded serious to me, despite how much money Meta seems to be throwing at it. For something with so much promise, and so many obvious challenges to attack first that Meta seems to be ignoring, what are they even doing?

This is the absurd logical endpoint of free market fundamentalism. “The market will fix everything!” Including, apparently, encroaching floodwater.

I do have to say though, after spending awhile looking at houses, that there are a crapton of homes for sale for very high prices (>$1 million) in coastal areas NASA is more or less telling us will be underwater in the next few decades. I don’t get how a house that’s going to be underwater soon is worth $1 million, but then I’m never been a free market fundamentalist either so 🤷 Maybe they’re all watertight.

(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.

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.

So. Some bits.

i := fIndex(xs, 5.6)

Can also be

i := Index(xs, 5.6)

The compiler can infer the type automatically. Looks like you mention that later.

Also the infer is super smart.. You can define functions that take functions with generic types in the arguments. This can be useful for a generic value mapper for a repository

func Map[U,V any](rows []U, fn func(U) V) []V {
  out := make([]V, len(rows))
  for i := range rows { out = fn(rows[i]) }
  return out
}


rows := []int{1,2,3}
out := Map(rows, func(v int) uint64 { return uint64(v) })

I am pretty sure the type parameters goes the other way with the type name first and constraint second.

func Foo[comparable T](xs T, s T) int

Should be

func Foo[T comparable](xs T, s T) int

@xuu@txt.sour.is that doesn’t seem to fit the spirit of the spec, at least by my read (I could be wrong obv). The example on Wikipedia’s webfinger page,

{
	"subject": "acct:bob@example.com",
	"aliases": [
		"https://www.example.com/~bob/"
	],
	"properties": {
		"http://example.com/ns/role": "employee"
	},
	"links": [{
			"rel": "http://webfinger.example/rel/profile-page",
			"href": "https://www.example.com/~bob/"
		},
		{
			"rel": "http://webfinger.example/rel/businesscard",
			"href": "https://www.example.com/~bob/bob.vcf"
		}
	]
}

and then the comparison with how mastodon uses webfinger,

{
    "subject": "acct:Mastodon@mastodon.social",
    "aliases": [
        "https://mastodon.social/@Mastodon",
        "https://mastodon.social/users/Mastodon"
    ],
    "links": [
        {
            "rel": "http://webfinger.net/rel/profile-page",
            "type": "text/html",
            "href": "https://mastodon.social/@Mastodon"
        },
        {
            "rel": "self",
            "type": "application/activity+json",
            "href": "https://mastodon.social/users/Mastodon"
        },
        {
            "rel": "http://ostatus.org/schema/1.0/subscribe",
            "template": "https://mastodon.social/authorize_interaction?uri={uri}"
        }
    ]
}

suggests to me you want to leave the subject/acct bit as is (don’t add prefixes) and put extra information you care to include in the links section, where you’re free to define the rel URIs however you see fit. The notion here is that webfinger is offering a mapping from an account name to additional information about that account, so if anything you’d use a "subject": "acct:SALTY ACCOUNT_REPRESENTATION" line in the JSON to achieve what you’re saying if you don’t want to do that via links.

@prologic@twtxt.net That was exactly my thought at first too. but what do we put as the rel for salty account? since it is decentralized we dont have a set URL for machines to key off. so for example take the standard response from okta:

# http GET https://example.okta.com/.well-known/webfinger  resource==acct:bob
{
    "links": [
        {
            "href": "https://example.okta.com/sso/idps/OKTA?login_hint=bob#",
            "properties": {
                "okta:idp:type": "OKTA"
            },
            "rel": "http://openid.net/specs/connect/1.0/issuer",
            "titles": {
                "und": "example"
            }
        }
    ],
    "subject": "acct:bob"
}

It gives one link that follows the OpenID login. So the details are specific to the subject acct:bob.

Mastodons response:

{
  "subject": "acct:xuu@chaos.social",
  "aliases": [
    "https://chaos.social/@xuu",
    "https://chaos.social/users/xuu"
  ],
  "links": [
    {
      "rel": "http://webfinger.net/rel/profile-page",
      "type": "text/html",
      "href": "https://chaos.social/@xuu"
    },
    {
      "rel": "self",
      "type": "application/activity+json",
      "href": "https://chaos.social/users/xuu"
    },
    {
      "rel": "http://ostatus.org/schema/1.0/subscribe"
    }
  ]
}

it supplies a profile page and a self which are both specific to that account.

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.

@mckinley@twtxt.net Thank you! I didn’t even know about signing and encrypting XML documents. Right, RSS is a little bit messy.

Unfortunately, the autodiscovery document in one of your linked resources does not exist anymore. What annoys me in Atom is the distinction between <id> and <link>. I always want my URL also to be my ID, so I have to duplicate that – unnecessarily in my opinion.

Also, never found a good explanation why I should add <link rel="self" … /> to my feeds. I just do, but I don’t understand why. The W3C Feed Validation Service says:

[…] This value is important in a number of subscription scenarios where often times the feed aggregator only has access to the content of the feed and not the location from which the feed was fetched.

This just sounds like a very questionable bandaid to bad software architecture. Why would the feed parser need access to the feed URL at this stage? And if so, why not just pass down the input source? Just doesn’t make sense to me.

Also, I just noticed that I reference the http://purl.org/rss/1.0/modules/syndication/ namespace, but don’t use it in most of my feeds. Gotta fix that. Must have copied that from my yfav feed without paying attention what I’m doing.

Your article made me reread the Atom spec and I found out, that I can omit the <author> in the <entry> when I specify a global <author> at <feed> level. Awesome! Will do that as well and thus reduce the feed size.

It is also too overrun with Tech Bros scamming people to get rich quick.

It was a fun ride back when I first bought in. But I have since cached out for my lambos and such.

@abucci@anthony.buc.ci Its not better than a Cat5e. I have had two versions of the device. The old ones were only 200Mbps i didn’t have the MAC issue but its like using an old 10baseT. The newer model can support 1Gbps on each port for a total bandwidth of 2Gbps.. i typically would see 400-500Mbps from my Wifi6 router. I am not sure if it was some type of internal timeout or being confused by switching between different wifi access points and seeing the mac on different sides.

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.

MoCA is a good option, they have 2.5G models in the same price range as the 1G Powerline models BUT, only if you have the coax in wall already.. which puts you in the same spot if you don’t. You are for sure going to have an outlet in every room of the house by code.

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
}

fig. 1

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)
})

I can tell the function the type being modified and returned using the function argument that is passed in. pretty cray cray.

@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)
