#Fediask #Fedihelp

Once I saved as PDF some emails from my previous job (Outlook). Those PDF come in a weird form factor, it looks they save the email as attachment, but they could also handle the cronological history.

Such "format" isn't read by the #GNU #Linux #PDF readers I usually use: #Atrill, #MuPDF, and #XPDF.

Rather than see the real content I get a slide that invites me to download Acrobat Reader...

Needless to say that not even the web browser and #Inkscape are able to open properly this PDF.

Eventually I had to use Acrobat Pro from my $WORK computer...

Besides being annoying and frustrating how do you ooen, if you suucceded, those bastard PDF with #Opensource software, preferably on GNU/Linux and #BSD?

Thanks... 🙏

Как удалить JavaScript из файлов PDF

Как известно, внутри файлов PDF можно размещать скрипты JavaScript, которые будут запускаться на исполнение в браузере. Например, если загрузить этот PDF , то вы увидите результат выполнения скрипта: Это стандартная функция формата. Все разработчики браузеров знают, что PDF подобно HTML является активным контентом и может содержать исполняемые скрипты.

#Xpdf is a #PDF reader.

Xpdf is a simple program which displays PDF files. Xpdf can change how the PDF is displayed in a few ways, including inverting the colors. Xpdf also includes several utilities for extracting various things from PDF files.

Thanks to #WSL people can run #Linux tools on #Windows.

Think about it....

... a little more...

...nothing?

Let me give an hint: people can install an X server too (separately, either ##Xming or #Cygwin).

Nothing yet?

Ok, last tip: you can install #xpdf from #Debian #GNU / Linux.

Nothing?

🤦‍♂️

You can teach people how to read #DRM protected #PDF on #Microsoft Windows.

But that's not the most interesting lesson you can teach them.

Through this DRM violation you can show them how fragile is #Capitalism. 😉

And it's even more general: there are always ways to subvert an oppressive system, usually provided by the oppressors themselves.

#xpdf 4.02 is released!

I'm interested in simple/understandable computers, programming languages, open source, home brewing, and way too many other things.
