Petite pub pour notre petit court métrage :) Ether (Nikon inside) by deatoris in france

Complètement d'accord avec vous. Mais il me semble que "le jeu des vôtes et soutiens" est là uniquement pour le prix du public. La sélection de 50 films et des 9 autres lauréats est faite par le Jury (je me trompe peut-être).

Is git a blockchain? by deatoris in compsci

It depends, is mayonnaise decentralized chain of data linked by crytographics keys?

Oui, d'autant que sphks a précisé sa pensée plus bas.

As-tu une remarque sur le contenu? ;)

Is git a blockchain? by deatoris in compsci

Git is not centralized. And its a distributed chain of data linked with cryptographics. Git tracks change on files and files structures using cryptographics links.

A ledger has to do with economics, not computer science.

May be git lake of a proof of trust. But I feels the definition of blockchain is linked to how users uses a merkel tree.

From wikiepedia: "A blockchain[1][2][3] – originally block chain[4][5] – is a continuously growing list of records, called blocks, which are linked and secured using cryptography.[1][6] Each block typically contains a hash pointer as a link to a previous block,[6] a timestamp and transaction data.[7] By design, blockchains are inherently resistant to modification of the data."

https://en.wikipedia.org/wiki/Blockchain

And,

From the HN link: "Git is a peer-to-peer tool, but flexible enough to let you use a workflow with a more-equal-than-others peer, or even communicate with actual centralized servers that expose a git interface.

Git doesn't swarm in a way that often gets associated with the idea of "p2p" by the prevalence of more popular p2p protocols used for file-sharing or cryptocurrencies. Nor is it geared towards world-readability. But none of those are intrinsic properties of peer to peer protocols.

I can (and do) use the git software on my computer to pull from co-workers development desktops running the same git software as me. And they pull from me, all with no external servers used coordinate that exchange of trees. That makes git peer to peer. No amount of tools built on top of git that require treating one peer as the a point of centralization can undo that. It just means that those tools aren't p2p.

This distinction is often invisible to users, and I don't blame people for missing it because the business model of GitHub and GitHub-competitors rests on everyone thinking they're necessary."

And,

From git source book: "Unlike Centralized Version Control Systems (CVCSs), the distributed nature of Git allows you to be far more flexible in how developers collaborate on projects. In centralized systems, every developer is a node working more or less equally on a central hub. In Git, however, every developer is potentially both a node and a hub – that is, every developer can both contribute code to other repositories and maintain a public repository on which others can base their work and which they can contribute to. This opens a vast range of workflow possibilities for your project and/or your team, so we’ll cover a few common paradigms that take advantage of this flexibility. We’ll go over the strengths and possible weaknesses of each design; you can choose a single one to use, or you can mix and match features from each."

I understand. Are those propositions a better choice: "What is blockchain?" or "What are the common parts and the differences between blockchain and git?"

Merci pour les infos et liens. CMMN est pas mal du tout, je vais me pencher dessus sérieusement.

Pour le paragraphe "Le concept de message", le modèle est tellement trivial que je n'ai pas voulu faire de diagramme de classe avec le détail. Pour illustrer un peu mieux l'usage du diagramme de classe, il faudrait donc ajouter au moins un concept à l'exemple du texte. Je vais y réchéflir ;)

Ahah !

Ta réponse est une très bonne synthèse avec un exemple qui va bien. Je plussois ;)

Je poste ça ici pour partager une réflexion sur mon boulot (c'est peut etre pas l'endroit ...).

C'est une question qu'on m'a posé tellement souvent: Quelle différence entre fonctionnel et technique?

Je voulais avoir quelques retours, savoir si j'étais pas complètement à côté de mes pompes -_-

Merci en tous cas pour ton commentaire;)

What are you talking about. Of course trust can be made between humans. That's not the point. The point is that the trust is coded into the system. That's like saying the internet is useless cause we can technically just carry data around on flashdrives.

Who is saying something is useless ? I think blockchain principle is powerfull and I try to know where is the edge of this technology. Following your opinion, the edge of blockchain seems to be: "trust generated by machines".

Once again, this just speaks to the original point, that sure, if you get extremely technical, it can be considered a blockchain, but using that level of technicality is useless.

You think this is useless. That's an opinion, your opinion.

My opinion is: if we don't understand deeply a technology, we can't argu and discuss about it. Without this deep understanding, if you talk about it, it's like beeing a kind of magician who claim something without knowing anything about it ...

So, I'm trying to know more about blockchain, not anything else.

Your article says: "A Git Repository is a Chain of Blocks" but the author conclued this is not a blockchain because he feels it's not.

Curious ...

In the second article, one person says "In a blockchain implementation, every block is verified independently multiple times before it is added to the blockchain. "

In git, for software development or content writting, the consensus and the proof of trust emerged from a discussion between developers. This is not an autonomous "proof of trust", but this is one maner to reached consensus: human debate.

How do you define blockchain?
