@stigatle@yarn.stigatle.no I think I understand NATO’s hesitation, but at the same time if this drags on and on for years then it causes massive loss of life and is even more dangerous for everyone. If that nuclear power plant melts down, whether because Russia causes it directly or because of an “accident”, then all of Europe can be blanketed with fallout. The longer this goes on, the more likely that possibility (and worse ones!) becomes.

That is scary to be so close to Russia. I hope you’re doing OK.

@movq@www.uninformativ.de wow. I’d trade crow sounds for car sounds, or jet sounds, or leaf blower sounds, or lawn mower sounds, or…..100% of the time.

As far as fighting the birds goes, maybe they’re right, but probably it’d be better to re-balance the ecosystem so that crows aren’t so dominant? At least there are things to try. When it comes to reducing how much air travel people use, it takes a terrorist attack or a pandemic to affect it.

@abucci@anthony.buc.ci buuuuut it show when winter!

In the time scale viewed from the planets perspective, the climate has changed many many times.. The issue is whether that change that will inevitability come is hospitable to us meat bags. Or if we are doomed to take part in the next mass extinction event.

@mckinley@twtxt.net Yeah, that’s more clear. 👌

Systems that are on all the time don’t benefit as much from at-rest encryption, anyway.

Right, especially not if it’s “cloud storage”. 😅 (We’re only doing it on our backup servers, which are “real” hardware.)

This guy is just such an idiot lol.

• There’s no such mass migration to “the south”. Tons of people are leaving Mississippi, Louisiana, Virginia, and New Mexico for instance. I don’t know enough about the states with net influxes like Texas and Florida but I suspect they have policies that make it attractive for people to move there
  
• Not everybody is able to take account of long-term trends when they make housing decisions. There are financial reasons, family reasons, educational reasons, etc that impact such decisions
  
• But of course, most laughably, cheap energy is fast becoming a thing of the past, and so the problem isn’t “solved” by cheap energy, it’s just kicked down the road. And ffs, cheap energy is literally causing the very heating that he pretends air conditioning will “solve”–like “solving” your drinking problem by staying drunk all the time
  

This oversimplification to drive some kind of political point is so embarrassing coming from someone who pretends to be a university professor. It sounds like a teenage doofus from a 1980s movie talking. He well knows all these things, but he decides to present these views anyway.

@movq@www.uninformativ.de I was visiting Germany once, and saw a guy try to load his bicycle onto the bike racks they have on the front of city buses. There were rules about when you could do that, which were posted on the bus stop sign, and I guess the guy thought this was a time when he could do that. But no, the bus driver disagreed. The bus driver got off the bus with a rule book, flipped it open to what I guess were the rules about bikes on the bus, and showed him the rules. The guy pointed at the sign, the bus driver said no and pointed at the book, and they went back and forth for I don’t know how long. It felt a lot like these videos lol

📣 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.

@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?

I have no interest in doing anything about it, even if I had the time (which I don’t), but these kind of thing happen all day every day to countless people. My silly blog post isn’t worth getting up in arms about, but there are artists and other creators who pour countless hours, heart and soul into their work, only to have it taken in exactly this way. That’s one of the reasons I’m so extremely negative about the spate of “AI” tools that have popped up recently. They are powered by theft.

There’s a link to the blog post, but they extracted a summary in hopes of keeping people in Google properties (something they’ve been called out on many times).

I was never contacted to ask if I was OK with Google extracting a summary of my blog post and sticking it on the web site. There is a very clear copyright designation at the bottom of each page, including that one. So, by putting their own brand over my text, they violated my copyright. Straightforward theft right there.

Went to the barber shop today. Got a nice talk and, surprisingly, my first “contract” to 3D print something. So, I spent the last hour reading about QR codes, versions and patterns and rescue data to embed an image in the centre of the code. Then it took me some time to convert it from a PNG to an SVG to an STL, so I can put it into Tinkercad to design the new plate. I now have a baseplate, a backplate with the QRCode & two smaller plates which I have to glue into placeholders on the backplate.

@prologic@twtxt.net @carsten@yarn.zn80.net

There is (I assure you there will be, don’t know what it is yet…) a price to be paid for this convenience.

Exactly prologic, and that’s why I’m negative about these sorts of things. I’m almost 50, I’ve been around this tech hype cycle a bunch of times. Look at what happened with Facebook. When it first appeared, people loved it and signed up and shared incredibly detailed information about themselves on it. Facebook made it very easy and convenient for almost anyone, even people who had limited understanding of the internet or computers, to get connected with their friends and family. And now here we are today, where 80% of people in surveys say they don’t trust Facebook with their private data, where they think Facebook commits crimes and should be broken up or at least taken to task in a big way, etc etc etc. Facebook has been fined many billions of dollars and faces endless federal lawsuits in the US alone for its horrible practices. Yet Facebook is still exploitative. It’s a societal cancer.

All signs suggest this generative AI stuff is going to go exactly the same way. That is the inevitable course of these things in the present climate, because the tech sector is largely run by sociopathic billionaires, because the tech sector is not regulated in any meaningful way, and because the tech press / tech media has no scruples. Some new tech thing generates hype, people get excited and sign up to use it, then when the people who own the tech think they have a critical mass of users, they clamp everything down and start doing whatever it is they wanted to do from the start. They’ll break laws, steal your shit, cause mass suffering, who knows what. They won’t stop until they are stopped by mass protest from us, and the government action that follows.

That’s a huge price to pay for a little bit of convenience, a price we pay and continue to pay for decades. We all know better by now. Why do we keep doing this to ourselves? It doesn’t make sense. It’s insane.

I have to write so many emails to so many idiots who have no idea what they are doing

So it sounds to me like the pressure is to reduce how much time you waste on idiots, which to my mind is a very good reason to use a text generator! I guess in that case you don’t mind too much whether the company making the AI owns your prompt text?

I’d really like to see tools like this that you can run on your desktop or phone, so they don’t send your hard work off to someone else and give a company a chance to take it from you.

@prologic@twtxt.net I’m a bit of a GPU junkie (😳) and I have 3, 2019-era GPUs lying around. One of these days when I have Free Time™ I’ll put those together into some kind of cluster….

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.

I played around with parsers. This time I experimented with parser combinators for twt message text tokenization. Basically, extract mentions, subjects, URLs, media and regular text. It’s kinda nice, although my solution is not completely elegant, I have to say. Especially my communication protocol between different steps for intermediate results is really ugly. Not sure about performance, I reckon a hand-written state machine parser would be quite a bit faster. I need to write a second parser and then benchmark them.

lexer.go and newparser.go resemble the parser combinators: https://git.isobeef.org/lyse/tt2/-/commit/4d481acad0213771fe5804917576388f51c340c0 It’s far from finished yet.

The first attempt in parser.go doesn’t work as my backtracking is not accounted for, I noticed only later, that I have to do that. With twt message texts there is no real error in parsing. Just regular text as a “fallback”. So it works a bit differently than parsing a real language. No error reporting required, except maybe for debugging. My goal was to port my Python code as closely as possible. But then the runes in the string gave me a bit of a headache, so I thought I just build myself a nice reader abstraction. When I noticed the missing backtracking, I then decided to give parser combinators a try instead of improving on my look ahead reader. It only later occurred to me, that I could have just used a rune slice instead of a string. With that, porting the Python code should have been straightforward.

Yeah, all this doesn’t probably make sense, unless you look at the code. And even then, you have to learn the ropes a bit. Sorry for the noise. :-)

@prologic@twtxt.net I get the worry of privacy. But I think there is some value in the data being collected. Do I think that Russ is up there scheming new ways to discover what packages you use in internal projects for targeting ads?? Probably not.

Go has always been driven by usage data. Look at modules. There was need for having repeatable builds so various package tool chains were made and evolved into what we have today. Generics took time and seeing pain points where they would provide value. They weren’t done just so it could be checked off on a box of features. Some languages seem to do that to the extreme.

Whenever changes are made to the language there are extensive searches across public modules for where the change might cause issues or could be improved with the change. The fs embed and strings.Cut come to mind.

I think its good that the language maintainers are using what metrics they have to guide where to focus time and energy. Some of the other languages could use it. So time and effort isn’t wasted in maintaining something that has little impact.

The economics of the “spying” are to improve the product and ecosystem. Is it “spying” when a municipality uses water usage metrics in neighborhoods to forecast need of new water projects? Or is it to discover your shower habits for nefarious reasons?

This is an upsert. So I pass a streamID which is like a globally unique id for the object. And then see how the type of the parameter in the function is used to infer the generic type. In the function it will create a new *Info and populate it from the datastore to pass to the function. The func will do its modifications and if it returns a nil error it will commit the changes.

The PA type contract ensures that the type fulfills the Aggregate interface and is a pointer to type at compile time.

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.

	_, algo := p.getAlgo(hash)

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!?

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.

@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.

(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
}

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? 🤦‍♂️
