Beta testers for calibre 9 needed

That will depend on your computer hardware. My system was chosen for speed for CPU, RAM and storage.

The documentation mentions 1000 books per hour but no mention of what type of machine that was tested on.

Kovid, I want to apologize.
I certainly overreacted.

I respect you and thank you very much for the tremendous work you do with Calibre, and it's this same respect that makes me fear and overreact that you could fall too easily into the trap of LLM solutions.

I am unaware of your complete and comprehensive opinion on such technology, which prevents a genuine, reasoned argued debate, and encourages speculation and emotion.

To summarize my opinion:

AI chatbot is the current great magic idea who promises to solve all our problems, and who has consistently and successfully demonstrated that it is the worst possible solution.
And all the current big-tech landscape is a example of that.

Certain things are maybe possible if you have sufficiently advanced technical knowledge and, above all, caution.
Especialy that AIgen/LLM are not longuer just technological solutions that could be considered among others, but it now deeply associated with negative connotations by a large part of the general public, even negative political connotations.
So choose AIgen/LLM is a very, very delicate choice.

That's mainly what I want to say: Be careful, Kovid.

Thanks.

@un_pogaz: IMO AI is not intelligent and never will be using the current architecture. But it's still useful, it doesn't have to be either intelligent or right 100% of the time to still be useful. For instace, it is, *vastly* more efficient at say searching for relevant information in many topics, than doing a Google search. You just have to remember to verify its results. If you shed the prejudice and actually use AI keeping in mind its strengths and weaknesses you will give yourself a nice productivity boost. For example, this whole bookshelf view that you sent the original PR for was actually based on an older PR generated using AI.

As for using AI in calibre, it will continue to be present, and used where it makes sense, in an opt-in manner. I am really not interested in debating this because I am tired of irrational people going either AI is nonsense or AI is Terminator. It's neither. In its present form it's a productivity boost for humans, in some contexts, when used judiciously.

An opt-in feature harms no one. I am *perfectly* comfortable simply ignoring anyone that takes issue with an opt-in feature. I have spent my life doing things that many many people have told me I should not do. This is one more.

And that's the last you will be hearing from me on the subject of AI.

Thanks.
This clear out all my concern.

using the new pages every book in my library shows an error the logs have

Traceback (most recent call last):
File "multiprocessing\connection.py", line 338, in _recv_bytes
BrokenPipeError: [WinError 109] The pipe has been ended

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "calibre\db\page_count.py", line 163, in count_book
File "calibre\library\page_count.py", line 244, in count_pages

File "multiprocessing\connection.py", line 256, in recv
File "multiprocessing\connection.py", line 353, in _recv_bytes
EOFError

this is the same for every book.

Has anyone seen this error and found a fix?

@SASSBS: That indicates the worker process used to do the counting is being killed on your system. Most likely culprit is security/antivirus software. Try rebooting in safe mode and doing the re count and see if it works.

[SASSBS]

thanks tried that but the same error.
I have the count pages plugin installed so I will just use that it's just annoying it shows Error when viewing book details.

You can choose not to display it in Book Details.

I did that because the value was considerably at variance with the number of pages in a book as displayed by my Kindle.

But that makes me ask, is there a tweak I can make somewhere in calibre preferences that could bring the two into agreement?

If you use the Count Pages plugin to display page numbers on your Kindle, you can experiment with its various options to bring your custom count close to that displayed by the new Pages column. If you don't use the Count Pages plugin, then probably not.

He can also set the page number generator to use the page number calibre is creating. If I go from ePub to KF8, the page number is the one from the ePub i get using Count Pages.

How do I do this? What and where is the page number generator?

Here's where you can change change what column will be used to generate the total number of pages for a Kindle eBook when you send it to your Kindle via calibre.

Plug in your Kindle with calibre running and your library selected. Right click Device (on the toolbar) and select Configure this Device.

That's for the bookshelf, not for Kindle.

I have asked for a tweak or something here:
https://www.mobileread.com/forums/sh...15#post4564615

It was explained to me that: the #pages column is a dynamicaly generated column and as such is not backed up in metadata.opf file (which was the main concern of mine) and that the existing books are not scanned unless you activate a bookshelf view (or somehow display the #pages column value). The newly added books are processed to determine the number of pages but that adds very little overhead. You can see for yourself: create a small library and activate the bookshelf view. You can see how quickly the books are processed as the bookshelf is displayed with proper book widths.

Currently I am looking at compiling my own version of Calibre with a bookshelf view option disabled in the layout menu/toolbar, so I do not click on it by mistake when switching between a list view and cover grid but it is not a high priority task. I use Linux at home, if I was a Mac or Windows user I would not even contemplate that, you MUST compile Calibre on Linux and it is a highly non-trivial task. Even just making sure that you have everything needed to compile the "vanilla" sources is a lot of work.
