Ooooh, you don't happen to have the code for the New Yorker decryption in a form you could send, do you? Or put up on github or even just give me the starting prompt…
replyOkay, a couple of hours later…thanks for the hint as that's fucking dark magic ;) and I now have access to the entire New Yorker again after around 15 years :)
replyInterestingly enough, i’ve been sitting on a project for the last 12ish years where i just took the FMloader lib and used that from C# to turn the djvu files into pdfs. All that was needed was a decompiler and an hour of banging my head on it. I published some of the results a few years ago but need to go back and actually build out a full app.
replyI'm trying to not do the naive pdf creation, where each page is just the raster. Trying to keep the JBIG2 bilevel, as I get better quality at lower file size. Using jpeg2000 too, where appropriate, but the pdfs are still x2.5 the size of the original. Though, I can have it spit out decrypted djvu files that are exactly the same filesize... I just don't like that format for archival.
replyIf you want the Rolling Stone or Playboy archives decrypted, ReconSuave on github has tools to do those. I got tired of waiting for him to do The New Yorker though.
Ive mainly been outputting them to high fidelity jpegs and then stuffing them into a cbz for portability. Works well went im reading on my ipad. As for the others i had them sorted out about a week or two after i decompiled the original binaries.
replyI’ve definitely kicked myself a few times for not posting about them sooner, but the fear of pissing off CondeNast tempered my willingness to show off
I don't think CondeNast cares.
replyDo any of the cbz readers handle jpeg2000? It makes a big difference in filesize without any quality degradation. Like 40% smaller, maybe more in some cases. You should tinker with that if you have the time.
Okular handles cbz that contain jxl with no issue. (IIUC both archive format and image format support is provided via a pluggable extension system but I don't recall the details because my setup has "just worked" for a very long time now.)
replyAlso FYI you can use mupdf to read cbz archives although I don't personally recommend it for that usecase.
What was your setup for this and did you have any preferences set in Claude to get started with something like this?
