Update on my Fibre to the Premise upgrade (FTTP). NBN installer came out last week to install the NTD and Utility box, after some umming and arring, we figured out the best place to install it. However this mean he wasn’t able to look it up to the Fibre in the pit, and required a 2nd team to come up and trench a new trench and conduit and use that to feed Fibre from the pit to the utility box.

I rang up my ISP to find out when this 2nd team was booked, only to discover to my horror and the horror of my ISP that this was booked a month out on the 2rd Feb 2024! 😱

After a nice small note from my provider to NBN, suddenly I get a phone call and message from an NBN team that do trenching to say it would be done on Saturday (today). That got completed today (despite the heavy rain).

Now all that’s left is a final NBN tech to come and hook the two fibre pieces together and “light it up”! 🥳

In-reply-to » @adi @prologic It's worth bearing in mind that

@adi@twtxt.net I think it is, and one benefit they have is that you can add third-party repositories to the F-Droid app as you discover them. So, for instance, if you know of a developer who pushes builds to an F-Droid compatible repository, you can add that to your F-Droid app and start tracking updates like you would for any other app in there. Can’t do that with Google Play!

F-Droid tends to focus on open source applications that can be built in a reproducible way, which limits the inventory (though of course tends to mean the apps are safer and don’t spy on you). There are non-free apps in there as well but they come with warnings so you’re informed about what you might be sacrificing by using them.

That said if you have a favorite app you get through Google Play, there’s a decent chance it won’t be in F-Droid. Many “big corporate” apps aren’t, and vendor-specific apps tend not to be either. But for most of the major functions you might want, like email clients, calendar apps, weather apps, etc etc, there are very good substitutes now in F-Droid. You’re definitely making a trade-off though.

What I did was go through the apps I had installed on my last phone, found as many substitutes in F-Droid as I could, started using those instead to see how they worked, and bit by bit replaced as much as I could from Google Play with a comparable app from F-Droid. I still have a few apps (mostly vendor-specific things that don’t have substitutes) that come from Google Play but I’m aiming to be rid of those before I need to replace this phone.

In-reply-to » (#khu32eq) @xuu "yet"? It's supported ipv6 for like 6 years now.

My home ISP has had a few prefixes allocated. They haven’t rolled of out yet because their custom CRM system needs to be updated to be able to allocate/bill for it. Along other reasons they gave when I asked last.

In-reply-to » been using the iphone for some days now, and I must say im impressed. I really like it. I will not buy android phone ever again.

Funny.. I would never buy an iPhone again. My wife switched back this last phone update and I can’t stand the interface.

In-reply-to » @darch I think having a way to layer on features so those who can support/desire them can. It would be best for the community to be able to layer on (or off) the features.

@xuu@txt.sour.is @prologic@twtxt.net Yarn.social without threading (as it would be the case in a “truncated” feed) does not make sense to me.

Put another way: Yarn.social is not twtxt. The content that we all have in our feeds really is much closer to a web forum or usenet or whatever. It’s threaded conversations. twtxt, as I believe it was originally intended, are short little status updates – that’s it. The formats of Yarn.social and twtxt might be very similar, but the content is vastly different and, in a way, incompatible. (As such, I think I understand very well that the original twtxt crowd is disgruntled.)

That proposed truncated feed doesn’t really provide any value, if you ask me. 🤔 It’d just be chaotic.

@prologic@twtxt.net I have updated to kinda follow this. It now redirects to other webfingers if the resource has a different hostname. I’m still not sure what I should put multiple services with the same domain name. Like if they were to have conflicting properties.

In-reply-to » 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.

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
}

In-reply-to » 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.

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.

In-reply-to » Hmmm, after fixing my feeds to move the <author> from <entry>s to <feed>, Newsboat marked all old affected articles as unread. IDs were untouched, of course. Need to investigate that. Had something similar happen with another feed change I did some time ago. Can't remember what that was, though.

Great, last system update broke something, building from current master I get:

/usr/bin/ld: /lib/x86_64-linux-gnu/libm.so.6: unknown type [0x13] section `.relr.dyn'

What the heck!?

And it also appears that I’m not really able to reproduce this unread bug. It only kind of works a single time. And it has something to do with my config. Not sure what it is yet. I also noticed that the <updated> timestamps in the entries somehow shifted between the old and new feed. Da fuq!?

In-reply-to » Trying to figure out what sql query maddy does to change user passwords, but first, i'm looking for the subcommand that actually does that... on the source code

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

In-reply-to » 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.

(cont.)

Just to give some context on some of the components around the code structure.. I wrote this up around an earlier version of aggregate code. This generic bit simplifies things by removing the need of the Crud functions for each aggregate.

Domain Objects

A domain object can be used as an aggregate by adding the event.AggregateRoot struct and finish implementing event.Aggregate. The AggregateRoot implements logic for adding events after they are either Raised by a command or Appended by the eventstore Load or service ApplyFn methods. It also tracks the uncommitted events that are saved using the eventstore Save method.

type User struct {
  Identity string ```json:"identity"`

  CreatedAt time.Time

  event.AggregateRoot
}

// StreamID for the aggregate when stored or loaded from ES.
func (a *User) StreamID() string {
	return "user-" + a.Identity
}
// ApplyEvent to the aggregate state.
func (a *User) ApplyEvent(lis ...event.Event) {
	for _, e := range lis {
		switch e := e.(type) {
		case *UserCreated:
			a.Identity = e.Identity
			a.CreatedAt = e.EventMeta().CreatedDate
        /* ... */
		}
	}
}
Events

Events are applied to the aggregate. They are defined by adding the event.Meta and implementing the getter/setters for event.Event

type UserCreated struct {
	eventMeta event.Meta

	Identity string
}

func (c *UserCreated) EventMeta() (m event.Meta) {
	if c != nil {
		m = c.eventMeta
	}
	return m
}
func (c *UserCreated) SetEventMeta(m event.Meta) {
	if c != nil {
		c.eventMeta = m
	}
}
Reading Events from EventStore

With a domain object that implements the event.Aggregate the event store client can load events and apply them using the Load(ctx, agg) method.

// GetUser populates an user from event store.
func (rw *User) GetUser(ctx context.Context, userID string) (*domain.User, error) {
	user := &domain.User{Identity: userID}

	err := rw.es.Load(ctx, user)
	if err != nil {
		if err != nil {
			if errors.Is(err, eventstore.ErrStreamNotFound) {
				return user, ErrNotFound
			}
			return user, err
		}
		return nil, err
	}
	return user, err
}
OnX Commands

An OnX command will validate the state of the domain object can have the command performed on it. If it can be applied it raises the event using event.Raise() Otherwise it returns an error.

// OnCreate raises an UserCreated event to create the user.
// Note: The handler will check that the user does not already exsist.
func (a *User) OnCreate(identity string) error {
    event.Raise(a, &UserCreated{Identity: identity})
    return nil
}

// OnScored will attempt to score a task.
// If the task is not in a Created state it will fail.
func (a *Task) OnScored(taskID string, score int64, attributes Attributes) error {
	if a.State != TaskStateCreated {
		return fmt.Errorf("task expected created, got %s", a.State)
	}
	event.Raise(a, &TaskScored{TaskID: taskID, Attributes: attributes, Score: score})
	return nil
}
Crud Operations for OnX Commands

The following functions in the aggregate service can be used to perform creation and updating of aggregates. The Update function will ensure the aggregate exists, where the Create is intended for non-existent aggregates. These can probably be combined into one function.

// Create is used when the stream does not yet exist.
func (rw *User) Create(
  ctx context.Context,
  identity string,
  fn func(*domain.User) error,
) (*domain.User, error) {
	session, err := rw.GetUser(ctx, identity)
	if err != nil && !errors.Is(err, ErrNotFound) {
		return nil, err
	}

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

	_, err = rw.es.Save(ctx, session)

	return session, err
}

// Update is used when the stream already exists.
func (rw *User) Update(
  ctx context.Context,
  identity string,
  fn func(*domain.User) error,
) (*domain.User, error) {
	session, err := rw.GetUser(ctx, identity)
	if err != nil {
		return nil, err
	}

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

	_, err = rw.es.Save(ctx, session)
	return session, err
}

In-reply-to » Hi, I am playing with making an event sourcing database. Its super alpha but I thought I would share since others are talking about databases and such.

I have updated my eventDB to have subscriptions! It now has websockets like msgbus. I have also added a in memory store that can be used along side the disk backed wal.

In-reply-to » I just built a poc search engine / crawler for Twtxt. I managed to crawl this pod (twtxt.net) and a couple of others (sorry @etux and @xuu I used your pods in the tests too!). So far so good. I might keep going with this and see what happens 😀

@prologic@twtxt.net the add function just scans recursivley everything.. but the idea is to just add and any new mentions then have a cron to update all known feeds
