Did you know there are leaf cutter ants in north America? As far north is Illinois!

So many cool ants in this video. I hope to keep most of these species some day... I have already kept Dorymyrmex. And someday I will keep the northern leafcutters... but I have to find them myself (flying) in NY or NJ

I’m old enough to remember professors who said learning CS wasn’t a part of a foundational education any more than learning to use a lathe was a part of interior design. I don’t think this is common today, thankfully. But, what aspects of computer science should be integrated into existing subjects (a word processor in English to write a paper) and the degree to which it is an independent subject remain nebulous.

Thing is, understanding computers changes the way you think about everything.

from logic gates to programming soccer playing robots is the 2nd chapter of my complexity lab manual. so many foundational topics.

iteration vs recursion
binary search
trial and error algorithms
data vs algorithm
hierarchical architecture vs distrubuted
genetic algorithms
iterating simple algorithm over space like cellular automata leads to complex behavior
watching how u can build a hierarchy from logic gates to a turing complete processor

I decided to find out if any progress had been made on the science behind why some ants are attracted to electrical fields. After filtering out exterminators (it's so demoralizing to search for information on creatures you love and find nothing but people who know nothing about them boasting about how they will kill them all) I found what looked like a blog. But, who the heck is "James Brown"? Never heard of the dude. Maybe he could be my new friend if he likes ants enough to blog about them!

Ant Chess Set:
Based on Camponotus

king - Alate Male
queen - De-Alate Queen (physogastric and extra large)
rooks - Alate Queens (Petite, for queens)
bishops - Median (Holding pupae in her jaws)
knights - Majors (huge heads)
pawns - Workers

How does this not already exist??? It's so obvious. One black side, one dark reddish-brown. Wooden board with natural bark edge.

barrygoldman1 ,
@barrygoldman1@sauropods.win avatar

@futurebird NOPE
ant "queen" is the most valued protected piece whos death is the death of th game so she is the King piece!

maybe alate "queen" can be chess Queen, most mobile

rook bishop knights can be workers of various castes or stages

rooks can be the workers that tend the colony queen (cuz castling!)

alate males r pawns! expendable!

An alien sends you through a transport device— on arrival every fungus, bacteria, mite, virus and plant has been eliminated from your body. You are now at the alien spaceport which is sterile, you can NOT acquire earth faunetta and floretta here. How sick would you be? Are you gonna die from this?

What is the best explanation you’ve heard for 1 not being a prime number? For me it’s “because it breaks everything in my programs since the loops won’t terminate” but that’s obtuse. “Because the God of math decrees it so!” is compelling, but shallow.

“it can only be divided by 1 distinct number” is contrived.

1 “feels” prime— it has the fewest factors. (Primeness being about NOT having factors) ruling it out for having too few? eh.

“it’s the zero of multiplication” is better… thoughts?

barrygoldman1 ,
@barrygoldman1@sauropods.win avatar

@futurebird if u made a program to factor a number into primes and 1 was allowed, how would you decide to terminate it?

barrygoldman1 ,
@barrygoldman1@sauropods.win avatar

@futurebird were u specifically thinking of factoring algorithms or would it break other algorithms?

barrygoldman1 ,
@barrygoldman1@sauropods.win avatar

@futurebird anyway i subscribe to the reason being that if 1 were prime, nubmers wouldnt have unique prime factorizations

The ant “foot” consists of a tarsal claw with two toes and the several segments above that I suspect are simply… well…floppy. Basically, I’ve seen no evidence ants can wiggle their ankles at will, but rather they seem to adjust the floppiness, or tension of the lower leg. The claws, however, show signs of dexterity, ants can control how sticky the soft pad of their foot is, but also seem to be able to grip and release with their claws. (how exactly are the muscles arranged?)

Another view that includes the segments above which I suspect to be “floppy” the ant leg is often covered in hairs.

When I pick up a wild ant such as this Camponotus pennsylvanicus minor worker I’m always anxious that I return her to her colony. I followed her after letting her go. She ran the full length of a football field then suddenly up a pole. Waiting there another ant of the same species. They fussed over each other. Grooming and feeding each other for several minutes. Then they tucked into a nook in the fence and went to sleep! I guess they won’t be taking me to their main nest today.

The sister she ran to find after the strange experience of running over my hand for a bit. They are feeding each other which ants do when nervous.

@futurebird camponotus don't form empires! lemme see... do colonies of ANY and spcies ABSORB other colonies?

  1. some steal workers

  2. some queens take over single colonies

  3. fire ants do a weird swapping/joining thing when they are young and casing out new territory
    https://blackskimmer.blogspot.com/2008/05/on-sexvines-and-boundary-crossing-in.html

Happy mother’s day to my Camponotus pennsylvanicus queen! She is nearly four years old this summer and the proud mother of nearly 700 beautiful daughters. Here she is today and years ago where her colony had only 30 ants. She has done an amazing job raising a huge colony!

Currently sowing a tiny garden for my field ants. I've kept field ants before and they didn't really thrive. I'm hoping if I can arrange for them to tend a heard of aphids they will be happier.

They colony is about 15 strong, and the queen is lovely shiny and black. They are also very nervous and freak out at every new sound and vibration. Will a box of green plants calm them? We shall see!

Simply putting colored paint on a few ants has let me discover that individual ants have certain spots they like best — Tulip likes to be on the highest point of this branch. If I don’t see her there I get worried. She’s a little camera (light) shy so documenting how often I see her in the same spot has been a challenge. She has preferred this spot for at least a whole month. Here are a few times I caught here there.

Tulip peers around the edge of the branch. She’s a good looking ant.
blurry tulip runs because so turned the light on.
Another shot that at least clearly shows it’s her since all you see is a blurry pink gaster.

The overhead for the AI on a minecraft ant is so great that the mod creators limit the colonies to just 20 ants to prevent lag. Fine for gameplay 20 feels like a lot.

Interesting the kind of things they do: remember the location of their nest, find a path back, collect leaves etc. are so taxing.

In the real world a colony of 1000+ is typical. Some colonies have millions of ants. And real ants have much more to "process" Kind of gives you a sense of the scale of the intelligence of a colony.

@futurebird @Woodswalked @mycotropic a whole ant mythology about wax and propolis. i think sometimes ants attack hives and i wouldnt' be surprised honeybees trap ants (dead, alive?) in propolis.

My current radical take that is driving the principal insane is the idea that to better educate our students about social media, online safety etc. we should have them set up and run their own social media on the school intranet.

And I get why. But, why do we just throw young people out into the wilds of the internet where they are surrounded by ads, creepy people, criminals etc.?

Part of why social media can be chaotic and destructive is because too many adults hope it just wont exist.

“Fluent Python” is an excellent example of a “good programming language book” — it’s not cluttered with “enterprise examples” it’s focused on how python works and goes into detail on edge cases. This lets one write code with real confidence that you know everything it’s doing. It is also written with the aim to justify why python is the way that it is. Which I need or I get irritated.

If you like python you should probably have a pdf or buy a copy.

Java has a interface* called “Set” but the documentation is nebulous & ominous. “may throw an exception” what? does no one even know? There isn’t even a method for intersection & union?! What is the point? I taught my students to use the set object in Python. It was an elegant beautiful experience— Thought we could do it in Java but I think I will just use arraylist, write my own damn methods.

I’m biased, but Java is always more annoying like this. ugh. (*this explains part of my confusion)
