@abucci@anthony.buc.ci So.. The issue is that its showing the password by default? Would making an alias to always include the -c help? We can probably engage Jason with a PR to enable a more hardened approach when desired. I’ve spoken to him before and is generally a pretty open to ideas.

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.

I have found the issue with this very subtle bug.. the cache was returning a slice that would be mutated. The mutation involved appending an item and then sorting. because the returned slice is just a pointer+length the sort would modify the same memory.

          CACHE         Returned slice          
original: [A B C D]     [A B C D]
add:      [A B C D] E   [A B C D E]
sort:     [E A B C] D   [A B C D E]

(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
}

Went on a hike this evening and brought my camera along. The 26°C felt much nicer than yesterday’s 33°C. I perfectly met a mate who also wanted to go for a quick walk, just like we planned it. The first half hour we went together and then I parted for the longer route to the local mountain. The sunset was absolutely brilliant, but the aftermath turned out to be very boring.

Photo 9 shows the entrance to a wasp nest next to the bench in the previous take. The greenery blocks most the view, though. Several individuals took off and returned. But it wasn’t too crowded. Nothing like at a typical honey bee hive at this point in time

What I found quite strange, there was quite a lot of smell of dead meat and butyric acid in the air. Hello hot summer. Both in the forest as well as in the village. I think I noticed those nasty odors at six or seven different places. Never experienced that before. Not to thaaat extent.

I just read that on average we get about 108 liters of rain per square meter in July. This year it has only been 6 liters so far. I truly hope that we get some heavy rain later this evening. But looking at the forecast I reckon it will only be a few drops, if at all. It’s supposed to get less and less with each day and even hour I look at the weather report. :-( Terrible 35°C at the moment. Bwäh!

The problem I have with the vast majority of social movements, left or right, is that they often lead to projection instead of introspection. Instead of person A trying to decide how person B can treat person C better, person A should try to decide how person A can treat person C better.

@prologic@twtxt.net That’s an even cooler slider, thanks! @mckinley@twtxt.net I’m also on the fence of changing my current background:

(44°C, what the heck!)

@off_grid_living@twtxt.net Beautiful! We melted at humid 34°C yesterday, it was awful.

https://beej.us/guide/bgc/html/split/index.html Beej’s Guide to C programming

@kt84@twtxt.net This is beautiful! I’d like to trade our temperatures from tomorrow on. Approaching and then exceeding 30°C here. 22°C today were alright.

My mate and I spontaneously decided to go for a longer tour today in 29°C heat. We ended up hiking 23 km in 4:30 hours. I had two liters of mineral water in my backpack and we bought a bottle of cherry limonade each on the way in. In the end we opted for pear limo at the same self-service fridge. What a great invention these small vending machines and self-service huts are! In Germany shops are closed on Sundays, so we would have needed to find an open restaurant (plenty didn’t survive Corona) with some detours.

It was my first time on that particular terrain. We went through some beautiful and quaint forest paths with scenic views. I forgot to put my SD card back into my camera, so no photos until my mate will send me his.

Now my feet a cooling off in a bucket of cold water. Superb.

Yesterday, we had a heavy thunderstorm in the evening. At first it wasn’t too bad, just thunder in the distance and then a few drops of rain for at most five minutes. That was it. Alright, I thought, it’s over, let me call a mate and walk to the dairy farm. The heavy clouds looked awesome, a bit threatening but mostly harmless and just beautiful. We decided on a small detour to the home made ice cream vending machine and got ourselves some expensive, but very yummy pineapple/mint, yoghurt and raspberry/basil tubs. Mint was super strong, had to eat three spoons of some other flavors to actually taste it. A few spoons in and then the thunder rolled in from nowhere. So we quickly headed for the dairy farm while eating our ice creams. Half way there the sky floodgates opened and we took cover under a tree at the local playground. A minute later we decided to climb up the slide tower, because it had a proper roof. A tiny bit of hail cam down, but nothing serious.

About 15-20 minutes the rain stopped and the thunder and lighning rolled past. So we continued our journey and I finally filled my two one liter bottles successfully. Every now and then it drizzled a little bit through the forest. We reached our homes and a couple minutes later rain hit again. Thunder and lighning went crazy. The sky lit up every few seconds and this continued through half of the night.

Right after I hung up to meet my mate, another mate called and reported a few villages north of us they experienced hail sized a bit under golf balls. But he luckily managed to get the car in the underground carpark in time.

Today, it rained the whole morning. This was great since the temperatures stayed below 20°C, so my walk was a real joy. It’s going to get close to 30°C tomorrow, though, gnarf, örks, bwäh. :-(
