What is Open-Source?

Open-Source is a way of developing software. The project’s source code
is available for free somewhere. When you download an open-source
software, you have access to its source code.

How do programmers manage to forbid the access to their source code when selling their software?

Most of the time, the code is compiled. When you download a proprietary
software, you actually download a compiled version of it: the source
code is not within it. You can do some reverse engineering in order to
decode it and manage to get some source code, but it will be quite a
degraded version: one that you cannot use to develop it further.

Why did you choose to join the Talao Team?

When I first learned about Talao, I was very excited and skeptical at
the same time. Was it yet another blockchain project with a useless
token? No. The team has a long history of being great entrepreneurs and
they did an awesome job in using the blockchain technology the right way
and not as an afterthought. I’m lucky to receive a lot of pitch-decks
related to cryptos and Talao was one of the very first one that looked
serious and smart in the way they lever the blockchain. One I wanted to
follow more closely and help if possible.

When you say that you were excited by the project, was it more because
of its technical aspects (blockchain technology, token etc.) or was it
mostly because of Talao’s concept?


It was both! I am quite close to the concept. And as a matter of fact,
the technical side of the project such as the blockchain are familiar
and really interesting to me, but there are numerous blockchain
projects. Talao has something more, which is that their idea is
appealing to me. There is a whole community dimension, more precisely
with the freelance realm. So, it is a mix of both!

What is your role in the development of this new project?

Talao has already used several open-source projects but wants to make
available a part of their code to the public too. I have been in the
open-source business for 15 years now, I manage a project called Symfony
which has a very large community of more than 800 000 people in the
world. Furthermore, Talao, beyond open-source practices, will have
challenges with management and/or construction and animation of quite a
large community, if it wants to be a success anyway. I have a lot of
experience in the management of open-source community and in the
development of open-source projects. Therefore, the idea would be to
share this knowledge so that Talao can develop itself faster and better.

What is Symfony?

Symfony is a framework for developers coded in PHP. In short, it is an
assembly of libraries that allows for the creation of websites. Today,
it represents approximately 7% of all the websites worldwide, i.e. 7%
use it directly or indirectly.
To give you an idea, I have been, for 4 years in a row, the largest
user/contributor on Github, which gathers several millions of users. It
is the biggest platform for open-source projects in the world.

Having worked on another open-source project, can you tell me the
differences between a project like Symfony and a project like Talao?


The organisation of open-source projects is very different from a
project like Talao. With Symfony, we are on a very social open-source
project. We, thus, have hundreds of people who contribute to the project
with a core team. The team is distributed around the world, and its
members are not necessarily employed by my company. New features are not
necessarily dealt by the original company, but by the community itself.

And is this a challenge for the use of open-source practices?

It is indeed a big challenge. Because you need to be able to fit the
long-term vision of the project with the short-term needs that the
different individuals inside the community have.
My job, as leader of the community, is to make sure that all the
contributions fit correctly the long-term project’s framework.
It sometimes means to refuse features because they do not fit in the
project.

Could we think about creating a specific token in order to fund
open-source projects?


Yes, and there are some projects doing it already. …
