Why do we open PDFs dozens of times a day and what makes them seem free?
Combien de fois par jour est-ce que vous ouvrez un PDF ? Rapport, facture, contrat. Tout le monde a adopté ce format parce qu'il est public et gratuit. Enfin, en théorie, car Adobe a pourtant réussi à s'en approprier le quasi-monopole pour en faire une véritable machine à cash. Et s'il y a bien quelqu'un en mesure d'expliquer ce tour de passe-passe, c'est Guillaume qui a construit son propre générateur de PDF. En creusant dans les entrailles du format, il a découvert les rouages d'une mécanique aussi géniale que sournoise qui remonte à l'origine même du format. Est-ce que justement pour planter un petit peu le décor, tu peux nous raconter l'origine ? de uh de PDF. Parce que ça n'est pas vrai ça n'est pas tel quel chez Adobe de ce que j'ai compris.
Non non
It's an idea that's a bit long, we can remonte it at super long. The debut is really Xerox, which is an entrepreneur American who has photocopied. It's a boat who is the East Unit. At the base, it's not for a boat of the tech tech, but they have many innovations.
Okay.
And it's a boat that has been and developed the photocopy.
And he
is precursor of other
things. It's a little berceau of the technology, the silicone value, just a truck that's the Xerox Park. Exactly.
You have the souris, the programmation orientated objects, you have Smalltalk, one of the languages that are the base of the programming object that was invented later, this will be the interface graphics, so. The
programmation orientated objects has been invented by Xerox?
It has been invented in the centre R ⁇ D. And in fact, the interface graphics, that's fine. But in fact, we know that between graphics and the PDF there a chemically common. It's so bad that it's so good that. In the event, we have the male of all the demos, which is a video incredible. If you haven't seen it, it is formidable. He presents who have a video on live, there are things that are hypertext, although we are in the year 10. If you have this, it's absolutely incredible. are known in this berceau-là, think that Xerox se rends compte of the four ideas that he has at the moment, and they're gonna pass a couple of two. About these
people, you have two who are interested in the app John Warnock and Charge Charles Geske. I don't know if you can.
The idea is to say we are in the day 80 years and there's a lot that develops. We have too much the information in the entrepreneurs and the ordinate personnel that we're saying that in the entrepreneur there's really a way to have a system for the impression, so we can have a document and imprimation. So there are imprimants that exist, but it's very complicated, there are plenty of technologies very different. People that you have, these imprimants that have text on these lights of feuilles of paper with a pointilling entre and the codes. So it's an imprimante that impriments. It's in growth machine to be automatically, you can see.
Cela veut dire que si on veut faire la même image avec plus ou moins de granularité sur le document, je vais avoir besoin d'avoir deux, trois, quatre formats d'image différents parce qu'on n'a pas la même résolution. Although fundamentally restored the memes traits, the memes, the memory. The idea that a fish
imprimed by different and completely hors de portée, en fac.
But imprimer at the way, design, do dessin vectoriel, designs courts or designs dropped. You have to provide a language for their parallel, a language to explain what I've impriminated on the foil of paper. And their idea is to say we should have a format, a language, that permit to say an imprimante I want imprimer that text at that end, I want to imprime that line at that end, I've made that image at that end.
How did the PDF format originate at Xerox PARC and evolve through PostScript?
And it's not what they invented, they will work with this idea. The project is appalled PostScript, which is more utilisated already. And it's a language of description of what we imprim in a feu of paper. He part and they create an entrepreneur that's approached Adobe and the mastodon that we have already.
Parce que comment l'entreprise, l'origine de l'entreprise adobe, comment elle gagne de l'argent en fait ?
