people, if two parallel lines meet at infinity, can it mean they form a polygon?

Well, you chose the boring bees. The Meliponini stingless bees have much cooler names.

I got dengue this year.

A week of pain and extreme weakness.

Don't recommend.

@blaue_Fledermaus@mstdn.io avatar

@Toes
Main symptoms are joint pain, pain behind the eyes, weakness (I felt couldn't hold myself up out of bed for more than 15min), and more dangerously a large drop in the number of blood platelets (mine got to half the healthy expected minimum), for some people it becomes hemorrhagic.

@Mouselemming
I think for the extreme cases when it becomes hemorrhagic.

Thankfully, it's uncommon. But it's more likely if one has gotten it before.

The only good thing about the far-right is that it's always eventually autophagic.

Small #flood in my city today. The main river rose 7m in 24h, but thankfully, it has now stopped rising, and it shouldn't rain for the rest of the week.

My understanding as a layperson: probably stuff is probably around here somewhere, probably.

There were no "good guys", there were bad guys against worse guys.

The Allies were happy to support the nazi/fascists as a counter to "communism" until Hitler got too greedy

Why ask for feedback if you’re unwilling to listen?

@khalidabuhakmeh
Thinking that feedback means validation?

For a lot of things in ActivityPub, there are almost direct parallels in NodeBB. An as:Note object pairs well with a NodeBB post, an as:Person is a NodeBB user, etc.

One thing that didn't map 1:1 was the Delete activity, which at surface level, seems rather straightforward — just delete the object! However, once you dig in, there are some additional considerations:

  • in NodeBB, we have two separate states for content removal.
    • A delete, where the post is still present (but its content unavailable to non-privileged users), and a
    • A purge, where the post is scrubbed from the database entirely, and all references to it, removed
  • in ActivityPub, there is a single activity, as:Delete
  • Implementors may opt to replace the object representation with an as:Tombstone (how quaint!), but they may also just opt to use a 404

So there are some nuances that are left intentionally vague.

Kaniini on SocialHub makes the argument that a Delete should be treated like a cache invalidation, which has its own merits.

This is how NodeBB will interpret the protocol specification, and how we will align it with our own dual-state post deletion mechanic (delete & purge):

  1. When a local post is deleted, we will federate out an Update(Tombstone) referencing the id
  2. Afterwards, if the content is retrieved, an as:Tombstone will be served.
    • Deleted posts in NodeBB still maintain their place in the topic, so when the context is retrieved, the note will still be present in the collection.
  3. If we receive an Update(Tombstone), we will delete the local representation of the post
  4. When a local post is purged, we will federate out a Delete(Note)
  5. Afterwards, if the content is retrieved, we will serve a 404
    • The note will no longer exist in the context collection
  6. If we receive a Delete(Note) (or Article, or Question, etc.) we will not delete it immediately. Instead, as kaniini advises, we will attempt to retrieve the object from the origin:
    • If we see an as:Tombstone, we will delete the post (soft delete)
    • If we encounter a 404 or 410, we will purge the post (hard delete)

I'm writing this out less as a guideline for myself, but to solicit opinions and to give others a chance to point out if I've interpreted the spec incorrectly.

@julian
I don't know how it works at ActivityPub level, but would it make sense to represent a soft delete as an update to the visibility of the object? Like as a Mastodon user, if I changed a post to private?

If there's one person that deserves the title of "evil genius" is probably Getúlio Vargas:

  • played fascists and communists against each other to attain power;
  • immediately turned against fascists;
  • kneecapped communists by giving a bunch of workers' rights and other policies that made him known as "big father of the poor";
  • unified Brazil with a bunch of genocides;

  • avoided a coup and resigned restoring democracy;
  • got re-elected;
  • saved democracy for a few more years by committing suicide in a way that frustrated another coup.

Obviously very controversial and considered both the best and the worst president Brazil ever had.

The war was not against nazi/fascism. The Allies were happy to support them as a counter to "communism" until Hitler got too greedy.

It might have a higher initial upfront cost, but the return on investment over a plant's whole lifetime makes it one of the cheapest. And even then, they don't take long to break even.

I've found this reference that seems good:

https://www.world-nuclear.org/information-library/economic-aspects/economics-of-nuclear-power

There's certainly more, but I'm not nuclear powered and don't have the mental energy for online debate 😁

It looked suspiciously biased. I'm going to research more.

@Sterile_Technique
Not catholic, so I don't know their official position, but as I understand, in extreme circumstances any liquid will do.
Part of it involves the idea of "washing", or "being washed", so solid water or water in solids would not count. And also the idea of purification, but many use dirty river water.

It was weird seeing people on the internet horrified by pineapple on pizza.
Around here, most pizzerias have 50-100 toppings, and pineapple is probably among the tamest.

Guava jam?
Hearth-of-palm?
Beef/chicken strogonoff?
Potato puree?

I did a blood test today.
While I'm feeling much better, my number of platelets is still less than half the minimum it should.

I guess I should avoid getting stabbed.

Was feeling much much better today. Even managed to walk to a long overdue visit to the barber.

blaue_Fledermaus, to random
@blaue_Fledermaus@mstdn.io avatar

I thought I would be feeling better today...
Pains are much fewer, but I still can barely eat, staying out of bed for more than a few minutes is completely exhausting, and eyes are too tired for me to watch or read anything.
