What does HackerNews think of koreader?

An ebook reader application supporting PDF, DjVu, EPUB, FB2 and many more formats, running on Cervantes, Kindle, Kobo, PocketBook and Android devices

Language: Lua

You can still choose automation. The easier route for me is to use wallabag to save the article. Then on my remarkable tablet I can grab a very readable document with https://github.com/koreader/koreader.

One other option is to use https://github.com/danburzo/percollate to convert a webpage to a nice document directly. I use both tools depending on my needs.

You can also use Zotero paired with the Zotero Connector Chrome/Firefox extension for this, I use Zotero as my document archival in addition to my academic citation manager. The Zotero Connector saves any PDF or web page opened in your browser to a local PDF/HTML file, and for HTML under the hood is uses the SingleFile extension to package the whole web page, images and all, into just one file.

It works well - now I'm just looking for a good way to annotate/highlight the local HTML/PDF/ePUB files cross-OS cross-platform. KOReader (https://github.com/koreader/koreader) works pretty well for this with its new hash-based storage option.

On normal sized e-readers (6"), I use koreader [1] for pdfs. It has a good enough “reflow mode” that reformat the pdf to fit the screen.

I also find e-ink devices a lot better for long reads.

Remarkable is more geared toward handwritten notetaking. If you don't need such features and just want to read stuff, the high price is not worth it.

kobo-elipsa (and the all-new kindle scribe) have a similar large size (+stylus writing) at a somewhat lesser price.

Most kindles/kobos (and others too) support koreader [1]. this "app-mod" has a superb pdf reflow [2] mode that makes reading pdfs a good experience even on smaller displays (and these come with an even lesser price tag)

So koreader is the short answer. If you already have a kindle, give it a try. It is open source and easy to set up.

[1] https://github.com/koreader/koreader [2] pdf reflow is the pdf format equivalent to "responsive Web Design".

I have a KOBO Libra H20, it is very good. I loaded KOReader on to it which adds functionality (https://github.com/koreader/koreader).
If you have a kobo, I highly recommend checking out koreader[1], which is an open-source ebook reader and is highly configurable (to the point where you can even write custom css rules from withing the e-reader), integrates with calibre natively (you can even connect to your Calibre library over Wifi), has a solid support for CBZ (with features like auto-cropping the border around your comic, automatically or manually), and more.

Having used it, I don't think I could go back to Kobo's reader (and even less to Amazon's, which is a joke in term of configuration options).

I run oathtool on my laptop as "2FA". Arguably not "true" 2FA, but with strong non-reused passwords it's "good enough". There's a bunch of non-Android phones like the PinePhone and whatnot, which should be perfectly fine for what you want.

I recently got a Pocketbook HD, which is a small Linux-based eReader. You can run your own "apps" on it with a minimal amount of hackery (I use KOReader[1] for example). I've been thinking of trying to get some passport manager/2FA running on it as well.

It's got WiFi as well (which I never use), and bluetooth for music (which is pretty useful when reading in noisy trains etc.) Actually it would be pretty neat if it could do calls and SMS: it's larger than a phone, but I don't need to always carry a phone, and I usually carry my eReader if I'm away from the house for various things (e.g. when I went to IKEA today I carried it with me to have something to read during lunch).

Kobos let you install custom book-reading software without too much hassle. KOReader[0] is the most popular one. I like it because it allows for a ton of customization, can properly render pretty much any EPUB you throw at it (much better than stock), and can reflow PDFs (using K2pdfopt[1] under the hood). But there are some other alternatives, including Plato[2] (simple, easy to use, fewer features) and PBChess[3] (closed source, play chess on your Kobo).

The MobileRead forums[4] are quite active, you'll find a lot more there.

Alternative reader applications like koreader and plato open up more customization than the default reading app allows for.

I have installed KoReader[1] on my Kobo device and loving it. Less clutter and more functions in every way. Plus it has a NATIVE integration with Wallabag - I read all my articles on my eReader.

>Does anyone happen to know if there is a community-maintained dictionary somewhere?

I had the same question and saw KOReader[0] has the GNU dictionary [1] that is creative commons licensed. Oddly I don't think it is in git or accepting PRs or patches: they just say to email suggestions.

As an aside, I've had trouble trying to find a capable, free, Linux system friendly English-Esperanto dictionary for ages. It seems weird that there isn't an open source translated dictionary umbrella project.

See also KOReader [0], if jailbreaking is an option for you. The built-in column splitter works pretty well for the papers I've used it to read.

Check out koreader for Kobo devices. I've been using it for a quite some time and it adds some nice Calibre features such as wireless sync. Besides that the PDF support is leaps ahead of stock Kobo

https://github.com/koreader/koreader

Where are you getting that from? The github repo (https://github.com/koreader/koreader) lists many supported formats and features, including epubs.

Have you tried another PDF reader, like KOReader[0] or plato[1]? There's also [2] which looks really interesting for cases where you want to save time.

I want to point out excellent koreader[1] program for e-readers, that features RSS client. So you connect, fetch your articles and start reading without distractions.

For such use cases RSS is god-send and I am glad that substack and many blogs do support that.

Sorry, I never used any custom firmware on our Kobos. You see, I keep them offline, so I'd care less about security vulnerabilities in them (plus if they go online, its via guest network). Also, I am very content with the software on our Kobo readers (Aura One and Aura Two). I do use Calibre + USB sometimes. What am I missing out on?

It sounds pretty basic from what other commenters are saying, but you can install koreader, which is outstanding (and also supports PDF, DjVu, XPS, CBZ, FB2, PDB, TXT, HTML, RTF, CHM, EPUB, DOC, MOBI):

https://github.com/koreader/koreader

For a better PDF experience, you might want to try 'koreader'. The native PDF support on my Kobo Forma was so bad I was ready to return it, before finding this. It's an open source PDF/epub reader that you can install on Remarkable and other eInk readers. It's just an app - it doesn't replace or degrade any existing functionality.

https://github.com/koreader/koreader

Kobo's also are very hackable, It's easy to get a cheap second hand one, pop off the back cover, swap out the sd card with a bigger one with custom user environments and reader software[1] loaded on it and without any nagging to use a particular store. You can sync books/rss feeds/wallabag saved web pages to it over wifi with calibre. Put a bit of tape over the logo and you have a great white label, no distractions device.

Yes! Jailbreak thread: https://www.mobileread.com/forums/showthread.php?t=186645 (Note that in some cases it requires opening the plastic and ordering some cable off of Amazon.)

The only custom ROM I know about that supports Kindle devices is KOReader (https://github.com/koreader/koreader). I don't like its interface one bit, but feature-wise it gets the job done just fine.

There's also Plato (https://github.com/baskerville/plato) for Kobo devices, though KOReader works there as well. In my experience jailbreaking a Kobo device is much less painful.

There is also alternative open source firmware available for Kobo devices: https://github.com/koreader/koreader
Koreader and coolreader both based on crengine and dont use webview. Koreader devs forked crengine and now seem to be in the process of merging back. https://github.com/koreader/koreader https://github.com/buggins/coolreader
This looks amazing - and for folks like me with a Kobo, it instantly lead me to https://github.com/koreader/koreader.
It's possible they've replaced the Kindle's reader software with free software like Koreader: https://github.com/koreader/koreader

This is what I run on my Kobo - it's quite nice! It has an RSS reader, Wallabag integration, cloud storage integration, a Lua plugin API... but it can't open DRM'd ebooks.

This is what's frustrating about DRM for me: it restricts the software you can use to only software from huge corporations. Want to make a small tweak to your reader? Nope, you're not allowed.

I only buy ebooks when I can find a DRM-free source for them, which pretty much means Tor/Baen/Humble/etc. I could buy DRM'd books and strip the DRM, but I'd rather not support the practice; I'm more likely to buy a physical book in that case.

So that's the current state of available stuff - The ESP32 stuff is quite interesting because it's all you need for an IoT module and in the right version it even has enough RAM for full screen updates.

I don't know specifics about the voltage conversion yet (these screens need about -20V - 20V), but I reckon that if you're really frugal you could make a battery powered wall display for under 60€ with this stuff - and that's part 1 of what I'm thinking of doing.

Part 2 would be to stick in a Pine64 SOPINE System On a Module [6], put on a capacitive touch layer [7] and run a mainline Linux with KOReader and maybe even a Wayland compositor to be able to run any Linux app (the high contrast GTK theme seems perfect for this application).

All hopefully for under 200€, which is a lot less expensive than other e-readers if that size and a whole lot cooler.

Any tips?

Actually there are ways to install software on many ereaders. About 10 years ago I used PRS+ on Sony's PRS-500. Nowadays Sony's ereaders are pretty much dead, but there is alternative software for Kindle, Kobo and others. By quick googling I just found:

There's software which can be side-loaded on Kindles (and Kobos etc.), e.g. Koreader, written in Lua: https://github.com/koreader/koreader
With a jailbroken Kindle you can, for instance, install koreader[1], a feature-rich alternative ebook reader application that enhances the somewhat limited capabilities of Kindle’s native reader.

For instance, with koreader you can open djvus, epubs, fb2 (if you’re onto those formats), but what makes koreader especially appealing to me is that it is a far better pdf reader than Kindle’s native.

Or you can look for a pool of available hacks[2] that make Kindle’s overall usage far more suited to your own particular needs. One example is the screensavers hack that allows you to choose either to use your own images (somewhat interesting if you’re onto customizing them to your tastes); or you can, as I prefer, to use that last displayed screen as the screensaver, as this allows you to keep a book’s opened page in display while you are taking notes or doing some other book research related task.

Some of these new features are now so essential to my Kindle’s experience that I can’t imagine myself using an original one without jailbreaking it. Also, I have my Kindle since 2015 and I’m in no hurry to get a newer or more capable model. As it is, it is very tailored to my academic needs.

You may want to try out KOReader. It is an open-source "ebook reader application supporting PDF, DjVu, EPUB, FB2 and many more formats, running on Kindle, Kobo, PocketBook, Ubuntu Touch and Android devices". https://github.com/koreader/koreader

I haven't tried it, as I'm reasonably happy with my Kobo Aura 2nd Ed running the first-party software, so I'm not certain that it replaces the firmware on your device, or supplements it.

I was just reading about a couple of ereader apps this morning.

https://github.com/koreader/koreader

and a newer one that the developer just announced in a Reddit rust group:

https://www.reddit.com/r/rust/comments/7iu7q8/plato_a_docume...

Yeah, that would really be great.

Just yesterday I wanted to order the new Kindle Oasis because I think the hardware is perfect (good to hold, physical buttons, …) but was told by a coworker just before ordering it can‘t open .epub files.

Edit: Thanks for all the tips about .epub + Kindle. I just found out that there also is an option to install Software like KOReader[1] if one wants to go the Jailbreak route.

If you're on Android or an ereader and frequently read two-column PDFs, consider using Koreader: https://github.com/koreader/koreader
Funny coincidence, I'm developing okreader (https://github.com/lgeek/okreader), which is a package of u-boot, deblobbified downstream kernel images, Debian and KOReader (https://github.com/koreader/koreader) for a range of Kobo devices. I've been working with upstream KOReader developers to get the features required to use KOReader without the Kobo firmware. okreader replaces the whole software stack on the device.
Other alternative readers for kobo include koreader: https://github.com/koreader/koreader

Oh yes! At least Kobo readers are Linux and you can SSH in. You could even install another distro I believe. Some ugly hack could be rendering the display content on your machine and just sent the image over.

https://github.com/koreader/koreader uses Lua so maybe one could add some bidirectional or at least PC->Reader flow of data.

I wouldn't use my Kindle half as much if it weren't for KOReader [0]. Ironically enough for a dedicated reading device, Amazon's built-in reader app pales in comparison to this third-party tool. The killer feature for me is on-the-fly column splitting and text reflow, with the ability to flip to the original page view by tapping a corner -- this is critical for reading academic papers, which tend to be two-column PDFs. It also features contrast adjustment, more fonts, stylesheets, wireless syncing with Calibre, and support for many more file formats including ePub.

There's also a Gargoyle [1] port for interactive fiction on the go. It's less practical due to the input lag on the Kindle keyboard, but I still pull it out every now and again.

I really wish they'd bring back the Kindle Developer Program in a better form than what it was. My Kindle is jailbroken, and software like KOReader [1] and KindleExplorer [2] have become must-haves. In the case of KOReader, the flexibility offered is just miles ahead of Amazon's stock reader app—even though reading is the central purpose of the device.

It's not for the faint of heart, given the inaccessible brick-ness of the Kindle and its long, nerve-racking reboot time, but you can jailbreak your device and install KUAL (app launcher) and KOReader.

http://www.mobileread.com/forums/showthread.php?t=203326

https://github.com/koreader/koreader

ePub and PDF support, text reflow/cropping/reformatting (great for papers!), plethora of options from contrast to margins, custom fonts, per-document style sheets, etc etc.

You can also install things like Gargoyle for interactive fiction on the go.

Just make sure to set up BackDoorLock so that Amazon can't force an OTA update on you.

It's actually quite good if you "root" the device and install koreader[1](the original developer is the same guy who wrote the vnc viewer for kindle, that was mentioned in this thread), or its librerator fork[2]. In contrast to Amazon's practically unusable PDF reader, these open source projects support custom zoom levels, 2-column mode for academic articles etc. Another option is to use k2pdfopt[3].
