Would be interesting, but the ai images and writing makes me trust it less.

An early project on my CNC machine was a basic set of inside/outside calipers:

https://community.carbide3d.com/t/locking-register-calipers-...

It would be interesting to see what would be involved in making the digital files which would allow re-creating each of these objects.

Reading this in between studying information theory makes a good laugh. This is the most inefficient code I've ever heard of. It's basically unary.

(For background, the first popular optical telegraph wasn't created until ~300 years later, and used 98 visually-distinct coding symbols).

The entire website looks heavily LLM written/analyzed - and I'm not talking of the design which I'm fine with.

This devalues the scientific value a lot because every line must be checked for correctness and source.

The book itself is very beautiful and I'm thankful for the high quality pictures.

katzenq•1h ago
I at least appreciate the warning on unreviewed generated pages and excluding them from SEO until reviewed, but it's still all untrustworthy spam by default.
vehemenz•1h ago
There are, in fact, countless late medieval manuscripts just like this one. LLMs have been trained on many of them.

What scientific value are you looking for?

moffers•1h ago
The author says in the introduction that a certain amount of the book is verified. Presence of LLM-use doesn’t inherently make something of less value.
gradus_ad•54m ago
The problem with AI generated content is, it tells me you didn't care enough about the work to do it yourself. To understand it fully, to the point where you don't need or even want to hand the work off to an LLM.

Interacting with AI content makes me feel like I'm consuming something that was created purely for engagement farming. Not that human created content wasn't for engagement farming, but noticing an AI tell breaks the suspension of disbelief in a way. It devalues the relationship between creator and consumer, so that genuine care is not being shared. It's like I'm a cow being milked on an industrial engagement farm.

I am very happy to see people make use of AI to do previously impractical work, but the quality of writing on this page sounds like a poorly written middle school research paper.

> Not a diary, not a family chronicle - a tool book.

> As reliable as it says on each page - no more and no less.

> Pages without a special note have been editorially reviewed: carefully checked and corrected.

This sounds like an extremely interesting topic but the lack of care in the presentation is disappointing.

shevy-java•42m ago
> the quality of writing on this page sounds like a poorly written middle school research paper.

But that is typical AI quality. It is a fancified Babelfish 2.0 translator.

Some humans also use AI to "interact" with other humans. They don't seem to understand that this is a problem for some humans. When a human AI slops me, I stop all any every further interaction (assuming I can find out that this human did so. It is not always possible to find that out).

Gabriel54•30m ago
I don't like to frame it in terms of, "this person is using AI, so I am no longer interested in communicating", because it is not really the AI that is the problem. It is the lack of effort put into communication with another human. AI can be extremely helpful for some people (e.g., proofreading text if one's native language isn't English). But this use case is almost never a problem if done carefully because the original ideas were all there in the beginning.

I focus my frustration on writing that is circular, vague, unnecessarily explanatory, etc. In my experience this is a symptom of the fact that there were no original ideas to begin with.

amelung•35m ago
Maybe this is because of the translation, I guess the author has written the non-English version first and then got it translated into English with AI, adding some additional explanations if necessary.
shevy-java•43m ago
The knights did not have to deal with AI back then. It must have been a simpler life.

The author is transparent about the use of AI, but so many negative connotations in the site!!

      >I still have not found a place where truly every page of the Codex is described      and interpreted in detail. I want to change that. But as a single person, I can only take on a project this big with AI as a tool.

Can anyone tell me how they would have made the paper and the pigments used in the drawings (or would these be called paintings)? Is this water colour? Is it reasonable for me to make my own paper and paints following the same receipts that would have been used to make this book and its contents?
YrRight2PushBac•7m ago
As interesting as this appears, I've developed such a strong allergy to LLM writing that I simply cannot consume any of this content
yababa_y•34m ago
Do you often experience persecutory delusions in front of screens?

Immense amount of human care goes into projects that use AI, and usually the human care goes into the aspects that matter most. AI helps pull projects like this from years into the future, into the present. Time travel leaves some scorch marks, sure. More effort will get attracted into the effort, or the idea will finish its expression and the host organism will move onwards.

QuantumNomad_•26m ago
There’s nothing delusional about what he said.

AI is being used for the most part to shit out as much “content” as possible in order to show ads, sell courses and other products (bonus points if what is sold is itself also pure AI slop), or to finish tasks at work with as little effort as can be done, so that boss man is impressed by the velocity. “Who cares about quality? This is 2026, bro.”

The actual thoughtful use of AI is the minority case. Not the default. We humans are lazy, and when we can get away with less effort we put as little effort as we can into things.

Always were, just now this signal makes people aware of it and they don't like how it makes them feel.

lionkor•54m ago
OBVIOUS presence of LLM-use devalues something to the point that you have to wonder why a human is in the loop at all
lelandfe•50m ago
Is the author qualified to verify this book?
wise_young_man•39m ago
In ways it does though. There are telltale signs of AI writing that once you see it across sites repeatedly, it starts to be annoying to find.

Couple of immediate examples:

- The Codex has 154 pages. 127 of them have been reviewed, 27 not yet. - Each of the 154 pages gets a page of its own.

If an author doesn’t have time to write. Why should I give up my time to read?

tropicalhunter•36m ago
Can you point to any of those in the linked text?
iamacyborg•26m ago
From the first tool page. Clearly LLM slop.

> Löffelholz does not open his book with a showpiece. He opens it with a practical tool you can adjust: choose a size, clamp it, work.

Gabriel54•29m ago
Using AI to go through an old manuscript has nothing to do with writing up those same results with AI. These are completely separate concerns.
amelung•46m ago
OTOH, it also seems to draw much from https://kdih.badw.de/datenbank/handschrift/49a/4/1 according to the information on "Sources", which sounds genuine.
Isamu•16m ago
I feel that obvious LLM content like this adds value, and I wasn’t entirely put off by this. I see the text as plausible, I just would need to research anything here before repeating it or referring to it in some way.
Gabriel54•25m ago
That thought certainly crossed my mind, but having worked with people using LLMs for this purpose successfully, this instead comes across as taking a simple idea and asking {model} to expand this two or three sentence idea into a web page.
cwillu•16m ago
“carefully checked and corrected” is also the sort of thing that llm's like to insert when you tell them to carefully check and correct in the prompt, and isn't otherwise really a natural thing to write.
