My uncle used to be a medical librarian. He said that when ebooks first came out, he saw the medical students reading the ebook on their iPad or whatever they had, but a lot had the physical book, too. So I asked him why? He didn't know but he thought the students were taking notes on their physical book but were watching animation and looking at graphics on their ebooks. At the time, he said, the animation was really crude, but it was there. And ebooks were locked down to prevent people from tampering with them, so it was impossible for the students to take notes and highlight passages in their ebook.

[@cameron7374]

@dothemathright 1111 Well, if I want to write something next to a line, with an arrow pointing to something on that line it'd be rather hard for the ebook reader to know what exactly that drawing is meant to refer to. And it gets even harder when the text is on a different screen and the annotation needs to be repositioned. So you'd need to replace just writing on something with a system that allows people to take all the notes they want to while communicating the intent of their notes to the ebook. (drawing an arrow that points to a word isn't enough, the ebook needs to know that it is an arrow and what word it is pointing to. Same with marking text though that is a bit easier to do.)

[@lawrencedoliveiro9104]

18:43 The book publishers themselves destroyed a lot of the promise of e-books, by trying to impose restrictions on them above and beyond those on physical paper books. And also trying to charge more for them. I can remember all those years of rising paper book prices in the latter 20th century, which the publishers blamed on the rising cost of paper, ink etc. So you don’t think that moving to a purely electronic format, getting rid of those consumables costs, would see a drop in the price. Not a chance.

[@IznbranahlGoose]

Some issues I've had with ePub (not much experience with mobi) is that if you have a scientific reference with diagrams and math formulas there are often major problems displaying. -- I've seen one publisher get around this by creating specific CSS coding for each and every paragraph with a formula but it would be a whole lot easier if there were a way to incorporate mathML into an ePub which I'm not sure is possible (and if someone did it would most devices be able to read it)

[@phasm42]

It's looks to be more an XML format that's viewable in a browser because unrecognized tags are generally ignored by browsers.

[@vylbird8014]

Mostly. It also defines acceptable file types and metadata representation. It doesn't allow everything HTML could do - it sets a lot of limits to ensure that even an e-reader with a very slow processor and limited RAM will still be able to process a book. Image formats, for example: JPG, GIF and PNG are allowed, but JP2 and WebP are not.

[@trevinbeattie4888]

So when asked about the incident of copies of 1984 being wiped from people’s Kindles (and similar cases of disappearing ebooks), you went into an explanation of how DRM is used to tie a book’s encryption to a specific purchaser; but unless I missed something you didn’t actually cover what can make these ebooks disappear after having been downloaded. Or is it the case that ebooks are never permanently stored on the reader to begin with?

[@Megaranator]

I would say that the books were stored there but Amazon made the kindles delete them. Which was kinda DRM so I guess he used that to explain that DRM in ebooks is a thing and explained how it is usually done.

[@RickBoat]

Amazon sends update instructions that say "delete this thing" which is why i remove drm from all ebooks i buy

[@trevinbeattie4888]

In that case I would contend that the ability for a vendor to remotely send unsolicited commands to your device is not an issue with DRM specifically, but with proprietary software in general. You can’t completely trust software whose instructions you are not privy to.

[@IMBlakeley]

@@RickBoat That's my default too, same goes for Video DVD & BlueRay. There's been more than one proprietary format which was rendered useless by the company going bust.

[@vylbird8014]

It depends. There are multiple DRM schemes, and they work in different ways. The only one I am personally familiar with is used for PDF rather than Kindle books, but I can tell you how that works, and I imagine whatever Amazon uses works in a similar way. Firstly, the books are encrypted. The key is unique to that download - every time someone downloads the book, they get a different file. The book doesn't contain the decryption key. When the device opens that book, it determines that it is encrypted and reads the unique ID for that download. It then contacts the publisher or store servers and provides two things: The unique ID, and the credentials of the person logged in on that device. The server than checks that the credentials are valid and belong to an account which has purchased that book and downloaded that particular file and, if all checks pass, sends back the decryption key. This key is then stored in memory - never written to removable media - and used to read the book. It'll be retained in the device memory to allow for reading the book offline in future, until either a set period of time is passed or the device next has to reboot. In this particular scheme, if the store wished to revoke a book, they would simply clear the 'has purchased this book' entry for every customer. People would retain the files, but eventually their key would expire and they would be unable to re-obtain it, so the file would be useless. This is not describing Amazon's DRM though - it's how a completely different DRM scheme works, one which is a third-party extension for the PDF format. I forget the name of it, and I can't look it up while I am supposed to be working.

[@tekvax01]

(16:07) The 1984 book removal story was more than a Digital Rights Management issue. Kindle -lost the rights- [didn't have them in the first place] to sell the book in the [or never had them] -future- , so they decided to remove all the previously purchased copies from all of their e-readers! Which calls into question, when you purchase an E-book, what you are in fact doing is purchasing a license to READ that book. You do not own a copy of the book, unlike the hard and softback versioning model. That is to say, you own the paper and the ink of the book, but not the words, nor the story. But this is a major failing of purchasing today! You own a license to use the product, you do not own the product... This is a model that I tend not to agree with! DRM is a thing, and it is useful and important, however, the publisher or distributor should not be allowed to take that product away from you, once purchased. However, companies don't make any money selling paper, they do make money selling licenses to read said paper! Amazon was not thought of, and took quite a publicity thumping in the news, by deciding to remove the books as well as no longer selling it anymore!

[@RedwoodRhiadra]

It's not that Kindle "lost the rights to sell the book in the future". What happened is the person who put the book on the Kindle store *did not own the rights to the book at all* - it was *never* legal for them to sell the book.

@@adityapathak5761 Can you cite your source for this information? It is a well-known fact that Amazon has removed books from people's kindle devices on several occasions. That would lend me to believe that you, in fact, do not own the files, only a license to read the files, until such time, as they see fit to remove them.

[@adityapathak5761]

Please correct me if I'm mistaken.

I might add that I have sufficient knowledge to realise that Amazon likely can not affect your personal local files. But once again, that was not my point.

The web has had a reader format for a while, I don't think it would take much to re-purpose it as an ebook format, it's not like you can't add special attributes using the data-* format specified and then let non-supporting browsers just treat it as they currently do, doing it that way ensures support everywhere and graceful fallback in the event it is viewed somewhere that doesn't directly support the format, IE6 for example would just see a bunch of blocks and flow it like so, a little awkward to read in that circumstance but not by much

13:05 I think most (if not all) e-readers load all the chapters at once. After all, all readers I know are able to show the TOTAL amount of pages in the book. Can't do that when the reader only loads one chapter at a time.

[@Technizor]

I mean, each chapter is separated by a page break which means that it only needs to read each of them the first time it opens the ebook to calculate the "page numbers". It would only change if you update the reader settings (e.g. font size, line spacing), so when you are actually reading the book it can look at only the section you are on (perhaps preloading the next and / or previous section if you are close to either of them in the current section) and cache the page number calculations somewhere else.

[@ArumesYT]

@@Technizor That doesn't make sense. E-readers have more than enough memory to store the entire book. Reading chapters, then removing them again, and then read the compressed file again when the page numbers need to be recalculated or when you navigate through the book is completely unneccessary, it makes operation way too slow, and it drains the batteries. When an eBook is decompressed and in memory, it's way better to keep it there until the user selects a different book.

[@atimholt]

I know the Barnes & Noble Nook actually just approximates, based on *compressed* file sizes. I use a Windows/Android (/elsewhere?) reader called Freda, which you can set to do actual page count, but it takes an eternity any time you do something that causes a (re)flow in a large book. I've just set it to give accurate page count within a chapter, displayed next to chapter count (which might be the default setting-I don't remember).

In my experience any technical book is a mess as epub and I'd take a PDF any day. For fiction though (or I suppose any book without diagrams) epub is the better choice. We just need to work on getting rid of that encryption bug that got included by accident so we can actually own the books we paid for and manage our libraries the way we want to.

[@vylbird8014]

A technical book properly authored as an ePub would be perfect. The format isn't the problem, it's the production process - most technical books are written and edited primarily for printing. The PDF works because it is simply a direct copy of what the print edition would look like. The ePub version, if one is published at all, is usually just a sloppy conversion.

[@sangramjitchakraborty7845]

What would your design be for this use case?

[@SimonBuchanNz]

XML was the standard choice about 10-20 years ago. If they made it now it would be JSON. The idea was that these common vocabularies like DC would be useful for interoperability, and XML was designed to easily layer these vocabularies into each other with its namespaces, but in practice it largely turned out that it just made things more confusing to implement, because it's hard to reuse code for abstract ideas rather than specific behavior and you just ended up with incompatible interpretations everyone would need to handle differently anyway. Nowadays the focus is on heavily specifying specific behavior for a specific format, so reuse of formats is much more self contained, and doesn't need the kind of blending and layering of behavior XML is designed for.

You want me to pay for it protected by DRM? Give me 95% off and i *might* consider. And i dont mean 95% off of launch price, either. Even when i was still buying my games on steam, yes, some indie devs i knew i could trust, i bought it in early access if i allready liked what i saw, with AAA i waited at least a year or two becouse they have forced updates on people against their will more than once.

it's an interesting time when computer viruses can be isolated and characterized, but so-called human viruses have never been (let alone been proven to _cause_ diseases in humans). the metaphor, in other words, has more basis in reality than its referent!
