General Public License Version 3: A Legal View

The GPLv3
and LGPLv3
have been finally published and anybody working on open source should
be familiar with them.

Mark Radcliffe has made a
very good comparison of the version 2 and 3 of the GPL
. One thing
he doesn’t mention though is the or any later version clause,
which means that you could already redistribute a good amount of GPL2
software under the GPL3 license if the authors included the default
boilerplate text in the file headers that says either version 2 of
the License, or (at your option) any later version

Each version [of the GPL license] is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.

For instance the Linux Kernel (by omission) or the JDK
(explicitly) are licensed only with GPL2.

Español o inglés II

He echado un vistazo a las estadísticas de mi anterior pregunta (En qué idioma prefieres leer este blog?) y ha salido así

  • español 33%
  • inglés 35%
  • me da igual 31%

Gracias a todos los que habeis votado, voy a seguir escribiendo mayormente en inglés pero a ver si de vez en cuando pongo algo interesante sobre lo que se cuece en España en español o algo así. Y de paso a ver si escribo más porque un mes si hacerlo es muy triste…

Español o inglés

Mucha gente me pregunta, por qué escribes tu blog en inglés?

Escribo cosas bastante técnicas, así que supongo que todos los interesados en ellas serán capaces de leer inglés. Como la mayor parte del público al que está destinado habla inglés pues me veo obligado a escribir en inglés, y apenas tengo tiempo de escribir en inglés así que escribir en inglés Y español se hace imposible.

Ya intenté contar mis experiencias en español, pero entre que no tenía tiempo, que no parecían tener mucho interés y que cuanto más tiempo pasa menos raras te parecen muchas cosas, pues lo he ido dejando.

Después de esta explicación técnica, tengo curiosidad por saber las preferencias de los lectores hispanos, así que he creado una encuesta, a ver qué sale

A new company, DevZuz, and Maestro 1.2

This week the new brand for our company was announced.
DevZuz is the evolution of
Simula Labs, Mergere’s parent company. Don’t miss also the release of
, a distribution based on Maven, Archiva (repository
management) and Continuum (continuous integration) with the tools
needed to manage open source adoption in the enterprise.

I was going to write an entry about it, but as Brett
already won me at it
, I’m going to copy and paste and save time
for other entries 😉

Other than “What does DevZuz mean?”, the main question I
am getting is “Why change the name?”

The reality of the two companies today is that they have a single,
simple and clear goal: to help enterprises adopt open source
projects and development processes
. Unifying under a single brand
gives us the opportunity for a “fresh start” that reflects
that specific focus. Far from being the end
of Mergere
, we are continuing to do what we are doing well now,
but additionally making some very positive changes (particularly in
relation to our community involvement).

As DevZuz, we will expand on our development and support for
Maestro, which is an enterprise-ready distribution of Maven
technologies now coming up on its one-year anniversary. Maestro,
which remains a free download, provides the foundation that is used
behind the firewall to enable artifact-based development practices
(and consume open source technologies). We will continue to provide
support, training and consulting services for Maestro customers.

In addition, DevZuz can now provide hosted
that build on top of Maestro to help enterprises manage
their open source governance and support.

We are also expanding our network of partners
to provide additional services, and to continue to provide commercial
support for key open source technologies.

More information can be found at our brand
new web site
. There you’ll also find that we have released
Maestro 1.2

One of the exciting developments is a re-emphasis on our
contribution to the open source communities we participate in.
Mergere has made significant contributions to open source over the
last two years in terms of development resources, free services and
the contribution of the first free book about Maven 2. These will, of
course, continue – but as DevZuz, we have established specific roles
and practices to improve our community involvement. Our aim is for
our participation in those communities to be completely transparent.

Though DevZuz is not “the Maven company”, DevZuz is
committed to making Maven and its subprojects successful as a
community in it’s own right. In particular, we will be focusing on
helping produce more frequent releases in the community, in addition
to the tested Maestro product suite. You can expect a lot more to
come in this area – and this is exciting news for Maven users and
developers alike.

In addition to our continued participation in Maven, DevZuz is
leading the Eclipse
project proposal as a community effort.

I’m personally pleased with this direction – we have interesting
and different problems to solve while continuing to focus on open
source development.
