Linux Running in a PDF

Doesn't work, the document is unresponsive. I used a HP DeskJet 2820e Printer btw.

Posted few days ago: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=42891937">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=42891937</a>. Repo also provides some explanation&#x2F;info on how the machinery works.

Finally! I&#x27;ve been making the joke &quot;put Linux.js in a PDF so I can run Linux, inside a PDF, inside a browser, inside Linux, inside a PDF, inside a browser, inside Linux&quot; for far too long...

Using JS for this feels like cheating... I wonder if similar things would be possible with PostScript?

Finally, I can `rm -rf &#x2F;` in a PDF.

Copy 10 of these in an USB drive. Enjoy your mobile Kubernetes cluster.<p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=42681039">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=42681039</a>

At least three detections on VirusTotal, but I&#x27;m not sure if it&#x27;s significant.<p>ClamAV: Js.Trojan.Obfus-48<p>Cylance: Unsafe<p>Google: Detected

Set pdfjs.enableScripting in Firefox about:config to false.

But is there a Linux PDF editor that runs Linux in a PDF? Evince isn&#x27;t loading it for me...

Does anyone know if running PDFs through the following filter (as in [0]) prevent malicious actors?<p><pre><code> gs \ -dNOPAUSE \ -sDEVICE=pdfwrite \ -sOUTPUTFILE=clean.pdf \ -dBATCH \ dirty.pdf </code></pre> [0]: <a href="https:&#x2F;&#x2F;tex.stackexchange.com&#x2F;a&#x2F;481609&#x2F;29430" rel="nofollow">https:&#x2F;&#x2F;tex.stackexchange.com&#x2F;a&#x2F;481609&#x2F;29430</a>

Who the hell keeps making those? First I saw Tetris, now a whole OS. Awesome!

Missing from headline: It is a RISC-V VM.

Right below this in my feed:<p>&gt; Ingesting PDFs and why Gemini 2.0 changes everything<p>Be afraid.<p>Be very afraid.

Does it run doom? ;-)

Just because you can, doesn&#x27;t mean you should....

These &quot;dynamic pdfs&quot; are the anti-thesis of what pdf files are meant to be: static objects containing text that always looks the same. My state dept. of natural resources loves them which means all the regulations are now inaccessible. All I can see in the &quot;pdfs&quot; (not pdfs, pdf shells that are webpages) are the following lines,<p>&quot;Please wait... If this message is not eventually replaced by the proper contents of the document, your PDF viewer may not be able to display this type of document.&quot;<p>... because they pull down their actual contents using JS from some website. They are the anti-thesis to what a pdf file is meant to be. Truly the worst of both worlds and a huge step backwards in accessibility and longevity. All that a screen reader can read is the above text.

Doesn&#x27;t work in Evince or Firefox FWIW.

I have not updated my noscript pdf reader in years... The dreade update is coming up though: mupdf.

&gt; <i>Note: This PDF only works in Chromium-based browsers.</i>

I hear that CSS is Turing complete.

Damn this is actually interesting

Has anyone tried printing it? I&#x27;m afraid!

Taste is subjective, but this broke that barrier. It is just absolutely hideous. Good engineering work, but still a total abomination in itself.

Doesn&#x27;t work in Safari (?).

What’s next? GPT in PDF?

ingest this, gemini

I would really appreciate if someone could put a decent PDF reader, like Sumatra, into a PDF so I could have a portable and good PDF reader on locked down computers.
