Great show. If you liked it, Ruth Goodman and Peter Ginn has made several shows together along with another archeologist, Alex Langlands, which I think are even better.

Of these, I think my favourite is Victorian Farm (2009), where the gang has to bring a real Victorian-era farm back into working order and then live like the Victorian farmers did. Unlike the castle show, it benefits from the gang having to research and learn the old ways on their own, whereas the castle is a big project where they're being taught or directed by the crew who's already working there.

The other shows — Tudor Monastery Farm, Edwardian Farm, Wartime Farm, Tales from the Green Valley, etc. — are all thoroughly excellent.

A minor point, but Goodman is not an archeologist or historian, but she's very good!

I watched the Tudor Monastery Farm show first by random chance and also liked it a lot. Thanks for all the recommendations!

There is a great documentary series with three archeologists by the BBC about medieval castles featuring Guédelon as a real live example from around 2014. I really enjoyed watching this and highly recommend it.

Oh that's a real shame then. The resulting composite images are certainly artistically interesting to look at, and you can see the big-picture effects like sunrise/sunset and moon, but that explains why you can't see the gradual brightening at dawn, or degrees of darkness at night.

It seems like if you wanted to do this accurately, you'd need to lock exposure to handle a bright blue sky without blowing out -- both aperture and shutter speed. And lock white balance. The question is whether that would allow for sufficient sensitivity at night. But if you're just averaging color values across a section of sky and mainly looking for moon and moonlit clouds, I think it would, since pixel noise will get averaged out and the moon is bright.

Additionally to locking the exposrue time and aperture, one could also take multiple exposures, figure out the camera's light response function and fuse multiple exposures together into a single higher dynamic range (HDR) image (see OpenCV tutorial on that or Debevec et al. 1997) Assuming you can find the camera response for the very long exposure times at night _and_ the very short during the day, one could relate them to each other and display both for accurate visual comparison.

Is it possible integrate this in a notebook environment? This would be amazing for teaching C/C++.

As a ckpt that's cool, but I'd like to see it as a LORA so you can use any checkpoint you already have. That would (let's face it... will next week) be amazing.

jupiterelastica · 3 years ago

What is LORA in this context? Google only brought me to wifi networks :D

Think of it as information, not voltage. An XOR produces information. A lot of XORS with ANDs make a calculator which opens up an entire vectorspace of mathematical information.

jupiterelastica · 3 years ago

I try to. One similar thing comes to my mind: generative adversarial networks (GANs). If I'm not mistaken this is along the line of your idea of composing single ML models to bigger information processing units.

Do you, by any chance, have links or recommendations for material to read up on architectures that do consider ML models as composable gates?

What people are missing here is that you can setup feedback loops of models to get the "correct" content or whatever you want.

For example, If you get too much NSFW content put a NSFW detection step on top of GTP ("Is this response offensive") and have that model respond to GTP with "please repeat but with fewer bad words".

For accuracy you can add a Wikipedia feedback loop. "Does this response match information on Wikipedia?" if NO ask it to try again.

Think of these models as transistors or basic logic gates. The real power comes out when you link them together into more advanced logic like a Instruction Pipeline circut.

jupiterelastica · 3 years ago

Like, a generative model is a source of _some_ information that is refined with gates (classification models) conditional on the generated information?

The analogy to transistors and logic gates falls flat a bit when you consider that voltage is a rather simple univariate signal, while generated text is quite complex and multivariate. But I understand that the main point is the composability and filtering.

Because it’s async first, the client can use both push or pull to receive the events.

If you’ve used Git you’ve been using a CRDT (with manual pulls and manual merges). A better CRDT would do both automatically.

jupiterelastica · 3 years ago

So, client that was "offline" can just ask a participant to get the edits from his own last one (aka pull), send out bis own offline edits (push) and resolve from there, I See.

Actually, that cleared it up, thank you :)
