@prologic@twtxt.net: I understand the benefits of using hashes, it’s much easier to implement client applications (at the expense of ease of use without the proper client). I must say that I like the way the metadata extension is done. Simple and elegant! It’s hard to design simple things!

@prologic@twtxt.net On the one hand, twtxt has become more popular thanks to Yarn.social. On the other hand, subject and hashtag extensions took away the simplicity of the protocol. For example, it is impossible to understand which conversation (#base32hash) a tweet refers to or to reply to a tweet without going to a yarn.social pod. Compare with re: in this tweet which can be written without using any client at all

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.

@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 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.

I was inclined to let this go so as not to stir anything up, but after some additional thought I’ve decided to call it out. This twt:

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.

Very cool. I am digging the multipurpose use for this kind of parser.

@movq@www.uninformativ.de, well, yes, that has always been the case. Not just on jenny, but on Yarn. I can’t follow everything, and everyone. To see whether is a reply, a simple h on mutt shows the headers, and there you have it. That is not too convoluted, is it? I mean, if you really want to know–but why?–it is a simple key press. If I don’t see a context on something as obvious as the example you used, it is simply a reply to someone I don’t follow, and pretty much ignore. End of story. 😂

@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.

I maintain keys for my email addresses.. but like most in this thread i almost never receive encrypted emails.. other than the BTC exchange i use that sends automated mail encrypted.

I use IP over Alternating Current at home. The only issue is the bridges forget device MACs sometimes and I get weird states where I can ping a deviceA and the the internet from deviceB. But deviceA can only ping device B even though they are on the same subnet and default gateway.

(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.

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 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
	}
}

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
}

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
}

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
}

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)
})

fig. 2

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

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 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.

I did a take home software engineering test for a company recently, unfortunately I was really sick (have finally recovered) at the time 😢 I was also at the same time interviewing for an SRE position (as well as Software Engineering).

Got the results of my take-home today and whilst there was some good feedback, man the criticisms of my work were harsh. I’m strictly not allowed to share the work I did for this take-home test, and I really can only agree with the “no unit tests” piece of the feedback, I could have done better there, but I was time pressured, sick and ran out of steam. I was using a lot of libraires to do the work so in the end found it difficult to actually think about a proper set of “Unit Tests”. I did write one (in shell) but I guess it wasn’t seen?

The other points were on my report and future work. Not detailed enough I guess? Hmmm 🤔

Am I really this bad? Does my code suck? 🤔 Have I completely lost touch with software engineering? 🤦‍♂️

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.

It’s super basic. Using tidwall/wal as the disk backing. The first use case I am playing with is an implementation of msgbus. I can post events to it and read them back in reverse order.

I plan to expand it to handle other event sourcing type things like aggregates and projections.

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)

Alright, check this out. I just kinda completed today’s project of converting a jeans into a saw bag. It’s not fully done, the side seams on the flap need some more hand sewing, that’s for sure. No, I don’t have a sewing machine. Yet?

Image

At first I wanted to put in the saw on the short side, but that would have made for more sewing work and increased material consumption. As a Swabian my genes force me to be very thrifty. Slipping in on the long side had the benefit of using the bottom trouser leg without any modification at all. The leg tapers slightly and gets wider and wider the more up you go. At the bottom it’s not as extreme as at the top.

The bag is made of two layers of cloth for extra durability. The double layers help to hide the inner two metal snap fastener counter parts, so the saw blade doesn’t get scratched. Not a big concern, but why not doing it, literally no added efforts were needed. Also I reckon it cuts off the metal on metal clinking sounds.

The only downside I noticed right after I pressed in the receiving ends of the snap fasteners is that the flap overhangs the bag by quite a lot. I fear that’s not really user-friendly. Oh well. Maybe I will fold it shorter and sew it on. Let’s see. The main purpose is to keep the folding saw closed, it only locks in two open positions.

Two buttons would have done the trick, with three I went a bit overkill. In fact the one in the middle is nearly sufficient. Not quite, but very close. But overkill is a bit my motto. The sides making up the bag are sewed together with like five stitch rows. As said in the introduction, the flap on the hand needs some more love.

Oh, and if I had made it in a vertical orientation I would have had the bonus of adding a belt loop and carrying it right along me. In the horizontal layout that’s not possible at all. The jeans cloth is too flimsy, the saw will immediately fall out if I open the middle button. It’s not ridgid enough. Anyways, I call it a success in my books so far. Definitely had some fun.

@prologic@twtxt.net I have seen single use keys that are signed by a central PKI .. Keybase has one that uses a chatbot to generate the keys on the fly.

It just comes down to your threat model :)

I would HIGHLY recommend reading up on the keybase architecture. They designed device key system for real time chat that is e2e secure. https://book.keybase.io/security

A property of ec keys is deriving new keys that can be determined to be “on curve.” bitcoin has some BIPs that derive single use keys for every transaction connected to a wallet. And be derived as either public or private chains. https://qvault.io/security/bip-32-watch-only-wallets/

For instance I normally use the same RSA key/pair on all my workstations for my ssh client, because that’s me, no-matter where I am. The only exception to this rule is I usually create a separate key for any “work” / “ company” I am a part of.

i hope that after i’ve aged, I will approach technology with the mindset of either “how can i use this to make cool shit” or “how can i make this technology safer”.

Wikipedia article on Banach spaces: “Maurice René Fréchet was the first to use the term »Banach space« and Banach in turn then coined the term »Fréchet space.«” that is very cute.

Will have to take a look at Gogs. Ideally wanting it to be easy to have the same ease-of-use to setup a web page as Github and Gitea.

@benk@kwiecien.us I am using jenny (we chatted a bit on IRC earlier today). I have been using it for over five months now, I think. It is truly a joy to use, specially because you can use the power of Mutt/NeoMutt to read your twts.

What if i told you for a browser it doesn’t matter what the extension is.. it will use the file magic mime value instead.

@prologic@twtxt.net let us take the path of less resistance, that is, less effort, for now. I am going to be a great-grandfather before search ever get implemented locally, least one to search on “all pods”. In other words, let us don’t bite more than we can chew. 😹 Neep-gren!

@prologic@twtxt.net I fully agree with making it a pod-level setting (forget about user-level, let us not complicate things too much; we all know users know nothing). Should I send a latinum over for this, or will an issue just suffice? Neep-gren!

iOS has had a “Shortcuts” app for a while now which is very useful for scripting things on the device, and at some point grew the ability to run things via ssh, including piping input/output. It’s how I’ve done twtxt from my phone for a while now. I’ll clean up these two examples and post to the examples I’ve shared. http://a.9srv.net/shortcuts

Netflix Raises Monthly Subscription Prices in US, Canada

From a report: The standard plan, which allows for two simultaneous streams, now costs $15.49 per month, up from $13.99, in the Unite … ⌘ Read more

@lyse@lyse.isobeef.org that is a horrible idea. A mobile device isn’t a server. Having a mobile device pull raw twtxt feeds from everywhere on an ongoing bases, will be, at the very least, tolling on the device’s battery. Just at you, or even further, I will never use such thing.

@tamer@twtxt.net We’re not trying to compete with anything… If you’ve read About Yarn.social – In a nutshell I want to create an open, transparent social platform that respect’s folks privacy and freedoms. It must also be easy to use and down-to-earth where human interactions actually matter. None of this rubbish of manipulating what you see, driving up engagement numbers to serve your advertisers and all that garbage

I think y’all are missing something. I never used ftp as a schema; I’m saying the “ftp” hostname part with the “http” schema is amusing.

Hey @eldersnake@yarn.andrewjvpowell.com I just came across this cool little project recently. Not written by me sadly 😂 But seems like it would do the trick nonetheless 🤣 – How are you going with PageKite? Is it still working okay for your Yarn pod powered by the outback of down under? 😅 LMK if you’d like me to spin this up anad you can be my first tester 🤙
