Hier, on m'a demandé de réduire par 10 le poids d'un fichier pdf (document contenant beaucoup de photos de bonne qualité, sensé être simplement affiché ensuite sur un écran). Je m'en suis sorti en utilisant Ghostscript. La commande pour faire ça tenait en une ligne.

On me dit toujours que la ligne de commande c'est un truc de geek. Alors, comment font les gens "normaux" pour faire ce genre de choses (car c'est un cas d'usage assez courant en fait) ?

Looking for help from linux mint gurus - an update ate my disk!

I just allowed update manager to update ghostscript and now I'm getting a warning that I have 0 space left in my root file system.
My /bin directory seems to contain recursive X11 folders. I'm not sure how many because I'm worried about messing with it in case I cause more problems.

I'd appreciate simple suggestions about the best way to solve this. I'm ok with using synaptic and even the terminal (if I really have to). But if you're going to ask me to delete random file please explain why.
I've been using Linux for years but I don't consider myself an expert.

I'm running Linux mint 21.3 cinnamon on an AMD Athlon with a 500GB HDD.

Another step in my saga of converting my #XFig drawings into RISC OS #draw files:

I tried to print one of the draw files. Printer said what file?

Much debugging later, I realized that #GhostScript (which is at least 2 separate stages inside #Cups), doesn't like the fonts named in the files! (ps2ps is failing silently inside the CUPS scripts)

So I took the file I was working on and manually changed all the text blocks to be a known working printable font.

And it printed!

@Ariri unless you want custom-engineer your own #Markdown -> #LaTeX -> #Ghostscript pipeline like @fuchsiii did, consider #MkDocs as an easy solution to turn Markdown files into sleek #documentation with minimal configuration needed.

That should provide you with an easy way to present stuff in an intuitive way...

I myself can't he assed writing #HTML5 / #CSS3 / #JS6 or wahtever #cursed #WebApp #TechStack is trendy tthese days so I use #MkDocs all the time...

@MissConstrue @Lichtenbergian Good question.

I hope #Finale has some means to export #SheetMusic with #SMuFL-compliant #PDF or something similar that i.e. #MuseScore can import.

  • Cuz I'd assume that there's a way to let Finale export PDFs (if necessary via a "soft printer" like #GhostScript) of sheet music and a way to import that into competing solutions...

The best contacts with knowledge I'm aware of are @tantacrul & #DanielSpreadbury, the latter one leading the #Dorico team and being
on #Twitter...

We found #CVE-2024-29510, a format string vulnerability in Ghostscript ≤ 10.03.0. It enables attackers to gain code execution while also bypassing all sandbox protections.

This vulnerability has significant impact on web-applications and other services offering document conversion and preview functionalities as these often use #Ghostscript under the hood and an attacker can easily get #RCE. Ensure you are running the latest version!

Je sais qu'on peut utiliser ghostscript pour réduire la taille d'un PDF, mais je suis quand même surpris que tar ne réduise pas du tous son volume ?
Pour envoyer à un destinataire, c'est plus simple de pouvoir lui dire de décompresser pour retrouver la qualité originale que de lui envoyer un fichier refait avec #ghostscript ...
