To me, it looks like anything but rowboats are included ... If there exists a rowboat with an AIS transmitter, I guess it is included as well, probably in the "Pleasure Craft" category.
Some of those "Pleasure Craft" vessels does not look like dead serious entries, judged by the AIS information they supply! Seems like the only requirement for transmitting AIS signals is that you can afford the transmitter. No formal requirements. If there are any at all, they must be extremely loose. It takes a lot more to obtain a CB or VHF license!
Here in Canada you would get slapped with a hefty fine if you try to operate a VHF transmitter without proper license. And yes, they do monitor the frequency spectrum. Don't ask how I know that
SOLAS (Safety of Life at Sea Conventions) requires all ships of over 300 tonnes to have an AIS. Smaller crafts can have it but it's not required. In principle, once you have your VHF license you can install an AIS without much fuss.
It's sort of coding, right? There's a scripting engine, and a bunch of "database records"
It's kind of a guilty pleasure and I'm just curious, because I've contributed some mods to nexusmods (High Level Perks Modular and Full editions, Brews, and a few others) and I wonder if others here have too? It seems like the kind of thing some people around here might enjoy.
For those of you that haven't touched Fallout 4, it's kind of fun because you can replace all the content in the game with your own, and add your own logic to it and quests and such. it's coding but not, and game development these days require tons of effort before you get something satisfying, so sometimes it can be more gratifying to modify an existing game and produce new content for it. It's why I love Fallout 4 so much.
I'm kind of surprised at that, actually, given the nature of Fallout 4. Of course, I keep forgetting a lot of people on here probably get sick of coding in their downtime whereas I'm relentless. FO4 in its own way is just another dev platform.
I'm into GTA Online, and frankly I'd be happy if I could merely read my own data from it. I know they have a nice REST API that their Social Club uses to read a tons of stats, and I know someone documented quite a bit of it years ago, but it seems like their authentication has changed and what little I can find no longer works.
And I'm not gonna risk hammering their system with trial and error requests using my only account--at some point I suspect they'd just shut it down...
I don't see a math forum, so I'll tack on another math question here if anyone is familiar with abstract algebra and/or category theory.
I've been learning category theory and have gotten stumped when learning about different characteristics of morphisms - specifically monomorphisms and epimorphisms. A monomorphism is defined as "a morphism f: X -> Y such that for all objects Z and all morphisms g1, g2: Z -> X, f o g1 = f o g2 implies g1 = g2." In English, it means that if we take a morphism f and compose it with any two morphisms "leading into" f, if the results are equal that implies the two morphisms are equal. It's basically the injective (or 1-to-1) property but for morphisms. An epimorphism is the same idea but for morphisms that f "leads into." It's basically the surjective (or onto) property but for morphisms.
So here's where I'm confused: it's beaten into your head in textbooks to not think of categories and objects as concrete. The whole point is the morphisms. But how can you show characteristics like monomorphic or epimorphic behavior without analyzing the morphisms in a concrete object context? If you don't, how can you 1) guarantee the category is even equipped with the concept of equality? (not everything is a setoid), and 2) show that the equality holds per the mono- and/or epi-morphic definition?
I hope that makes some sense. I'm still very much in the learning stage on this topic
If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
Rating helpful answers is nice, but saying thanks can be even nicer.
I'm kind of in no-man's land on this topic. I'm not a mathematician enough that answers I've found to similar-ish questions provide useful insight to this particular question, but it's also a question that I'm not sure many non-mathematicians would ask
I just got really interested in it because it's a fascinating branch of mathematics.
