CentOS 6.1
Dec 12th
Ya salió la nueva versión de CentOS 6.1. Aquí tenéis las notas de la versión.
Como siempre se recomienda la descarga vía torrent:
Versión 32 y 64 bits:
http://mirror.centos.org/centos/6.1/isos/i386/CentOS-6.1-i386-bin-DVD1to2.torrent http://mirror.centos.org/centos/6.1/isos/x86_64/CentOS-6.1-x86_64-bin-DVD1to2.torrent
Se han demorado bastante, pero han consolidado varios de los productos de Red Hat Enterprise Linux que ahora están sacando de manera independiente, en un sólo instalador.
Indican que posiblemente que las siguientes versiones saldrán más rápido, porque al parecer ya han tomado idea de cómo RedHat está publicando sus productos.
Ya están trabajando en la versión 6.2 de Red Hat Enterprise, que salió recientemente, para sacar lo antes posible la próxima versión de CentOS 6.2.
Hay un nuevo concepto que es lo que llaman cr (continuos release) que son los paquetes de las siguientes versiones, que los ponen en CR para que puedas ir actualizando sin esperar a que salga el nuevo ISO. Mas información sobre CR aquí.
Tambien esta disponible la version 32 bits y 64 bits del LiveCD de CentOS 6.1.

DebConf12 Nicaragua fechas confirmadas (dates confirmed)

In English
DebConf12 Nicaragua dates confirmed
DebConf12 to take place in Managua, Nicaragua in July 2012
The Debian Project, the team behind the free Debian operating system, has confirmed the dates and venue for its next annual conference, DebConf12.
The conference will take place from July 8 to July 14 2012, in Managua, Nicaragua. In DebConf’s twelve-year history, this will be the first time it will be held in Central America.
Every year, DebConf allows new and existing Debian project participants from around the world to assemble, share knowledge, make collaborative contributions to Debian, and build tighter community bonds. Conference costs are largely funded by corporate sponsors who find significant value in enabling Debian’s success.
“The members of the Debian community in Nicaragua, working together with their fellow communities in Central America, are very excited to be hosting this event, and are happy to welcome our colleagues from around the world to join us in Managua at this very important and productive conference” says Leandro Gómez, leader of the local team for DebConf12. “This conference will boost the local Debian and Free Software communities and help to bring awareness for the Debian Project, with new contributors and enthusiasts from our country and the surrounding region joining the Debian community and helping Debian to build the best operating system.”
DebConf will be preceded by a day when it opens its doors to the general public, commonly called Debian Day. There will be talks and demonstrations about the benefits of Debian and Free and Open Source software in general to corporate, governmental, academic, and individual users.
The call for papers and registration will open in early 2012.
DebConf12 will be preceded by DebCamp, the yearly developer work sessions, starting on July 1.
The final calendar of the event is:
- July 1-7 2012: DebCamp, the yearly developer work sessions
- July 7 2012: Debian Day
- July 8-14 2012: DebConf12
- July 15 2012: Departure/cleanup day
En Español:
DebConf12 se celebrará en Managua, Nicaragua en julio de 2012.
El proyecto Debian, el equipo detrás del sistema operativo libre Debian, ha confirmado la fecha y la sede para la próxima conferencia anual llamada DebConf12.
La conferencia tendrá lugar del 8 al 14 de julio de 2012, en Managua, Nicaragua. En doce años de historia de la DebConf, esta será la primera vez que tendrá lugar en América Central.
Cada año, DebConf permite a los participantes del proyecto Debian, ya sean recién llegados o con experiencia en el proyecto, y que se encuentran repartidos por todas las partes del mundo, reunirse, compartir conocimiento, realizar contribuciones colaborativas a Debian y construir lazos más estrechos en la comunidad. Los costos de la conferencia son en gran parte financiados por patrocinadores corporativos, quienes encuentran un valor significativo en apoyar el éxito de Debian.
«Los miembros de la comunidad Debian en Nicaragua, trabajando juntos con sus comunidades amigas en América Central, están emocionados por alojar este evento, y están felices de dar la bienvenida a nuestros colegas de todo el mundo para unirse en Managua en esta conferencia productiva e importante.» dijo Leandro Gómez, el líder del equipo local de la DebConf12. «Esta conferencia estimulará a las comunidades de Debian y de Software Libre locales, ayudará a crear conciencia del proyecto Debian, con nuevos contribuidores y entusiastas de nuestro país y de la región uniéndose a la comunidad Debian y ayudar a
desarrollar el mejor sistema operativo.»
DebConf será precedida por un día donde se abren las puertas al público en general, comúnmente llamado Día Debian. Habrá charlas y demostraciones sobre los beneficios de Debian y Software Libre en general a la empresa privada, el gobierno, los estudiantes y los usuarios individuales.
El registro se abrirá a inicios de 2012.
DebConf12 será precedida por DebCamp, las sesiones de trabajo anual de desarrolladores, que comenzarán el 1 de julio.
El calendario final del evento es:
- 1-7 de julio de 2012: DebCamp, sesiones de trabajo
- 7 de julio de 2012: Día Debian
- 8-14 de de julio, 2012: DebConf12
