Closurism Updated +Created
Closurism is a term invented by Ciro Santilli to refer to content moderation policies that lock threads in online forums, preventing people from adding new comments from that point onward.
This is similar to deletionism but a bit less worse, as the pre-existing content is maintained. But new relevant content that comes up cannot be added in the future, so it is still bad.
The outcome of closurism is that new forum posts must then be made about up-to-date aspects of the topic. But then those may fail to reach the same PageRank, so most people never get the new information, or create new posts leading to useless duplication of work.
COCO dataset Updated +Created
From cocodataset.org/:
  • 330K images (>200K labeled)
  • 1.5 million object instances
  • 80 object categories
  • 91 stuff categories
  • 5 captions per image. A caption is a short textual description of the image.
So they have relatively few object labels, but their focus seems to be putting a bunch of objects on the same image. E.g. they have 13 cat plus pizza photos. Searching for such weird combinations is kind of fun.
Their official dataset explorer is actually good: cocodataset.org/#explore
And the objects don't just have bounding boxes, but detailed polygons.
Also, images have captions describing the relation between objects:
a black and white cat standing on a table next to a pizza.
Epic.
This dataset is kind of cool.

Ciro Santilli's hardware Updated +Created
One day, someone will invent a way to take the hash of a piece of hardware and see its history log, like software engineers do with version control. Until then, this is as close as you can get.
Ciro one day guessed that hardware would certainly be a slang for something naughty, and yup, here we are: www.urbandictionary.com/define.php?term=Hardware, drug paraphernelia. Read on!
Divergence Updated +Created
Takes a vector field as input and produces a scalar field.
Mnemonic: it gives out the amount of fluid that is going in or out of a given volume per unit of time.
Therefore, if you take a cubic volume:
  • the input has to be the 6 flows across each face, therefore 3 derivatives
  • the output is the variation of the quantity of fluid, and therefore a scalar
