I have been using Ubuntu 11.10 on ARM now for a couple of days and I have to say: It is great! Ubuntu has had a long history of supporting ARM Systems on a Chip (SoC) since 2008, but Ubuntu 11.10 is a significant milestone.

Introducing.. Ubuntu Server on ARM – Technology Preview

Canonical announced back in August that Ubuntu Server 11.10 would include the first ARM version of the product, and here it is. While this is just the first step on an exciting journey, it is worth to celebrate that the voyage has started. I look forward to see what 12.04 LTS brings us on this space!

Playing with Ubuntu on ARM (Toshiba AC100)

It is hard to really grasp the full experience of Ubuntu on ARM when you are playing with a development board. For this reason, we have released a demo image for the Tegra2-based (Nvidia) Toshiba AC100.

Running Unity 2D, it shows off  that Ubuntu on ARM is a great platform for computing, in a very compact design and with a very long battery life. For all these reasons, this is my system of choice to take to UDS-P.

If you have a Toshiba AC100, I encourage you to install Ubuntu 11.10 on it!

TI OMAP4 Panda Board

Powered by the Texas Instruments OMAP4430 processor, the Panda Board packs in “a dual-core 1 GHz ARM Cortex-A9 MPCore CPU, a PowerVR SGX540 GPU, a C64x DSP, and 1 GB of DDR2 SDRAM“.  Providing an affordable and competitive design tool for the embedded mobile space.

Ubuntu 11.10 on ARM is available in headless and full image for Panda. You can find download links and installation instructions here. You can also find there Ubuntu 11.10 for OMAP3 (Beagle Board).

Freescale IMX53 QuickStart Board

The IMX53 Family is oriented towards automotive solutions. Ubuntu 11.10 on ARM is the first release of Ubuntu to provide support for the IMX53 QuickStart Board. You can find download links and installation instructions here.

Linaro and Ubuntu

Both the TI OMAP4 and Freescale images are based on the Linaro outputs for those SoCs. This has greatly our capacity to support ARM development boards.

Canonical runs the Ubuntu Certification program, providing users with a verified list of Ubuntu compatible systems. For Manufacturers and partners that would like to understand better the certification program, Canonical publishes a guide available to download from the certification website.

We have recently updated the guide to include a detailed list of the components that will be tested for Oneiric. Each test listed on the guide is required for certification only if the system supports the functionality. For example, we do not run the bluetooth tests on a laptop that does not list bluetooth on its manufacturer specifications.

The list also contains tests that are run for informational proposes. This means that the result of those tests will be shared with the users but they will not determine if the system will pass or fail certification.

As usual, please let me know if you have any questions via launchpad answers.

Canonical, sponsor of the Ubuntu project, has announced that three Asus Eee PC netbooks will now come the Ubuntu 10.10 operating system pre-installed.

The company said the "sleek and lightweight" hardware combined with the Linux-based Ubuntu OS makes the devices "some of the most user-friendly PCs on the market", as well as providing cost benefits for organisations.

"Many businesses are turning to Ubuntu as they look for a cost-effective, proven, and easy to use and manage operating system that can be delivered on business-quality laptops," Chris Kenyon, vice president of OEM Services at Canonical said in a statement on Thursday.

One of the most exciting things about the Ubuntu 10.10 release has been the delivery of the Unity ‘shell’ in Ubuntu Netbook Edition. For the uninitiated,  this delivers a very different user experience to that in the main desktop edition. For a start the icons of the most popular applications are permanently featured on the left-hand side of the screen. This borrows more from the smartphone interfaces but is adapted for use on, in this case, netbooks. So there remains a workspace where users still have sufficient room to watch video, edit photos, create documents, play games, read the web, write emails – all of the usual tasks we use a computer for, day to day.

Everything is optimised however for the more limited screen space. It is sub-optimal for instance to simply port an interface from the full-screen world, shrink it and expect it to be a great experience. Unity does away with the bottom bar for example that Windows, Ubuntu and Mac users will be used to. This is actually a radical step, but in my experience at least, it takes no time at all to forget that there ever was a bottom bar. The result is considerably more ‘vertical space’ for to use  – again maximising the useful area on limited screen sizes.

One of the coolest things though is one that will be experienced by the fewest people at this point – touch. Unity is fully touch-enabled – those big icons are screaming out to have a digit poked at them. But as ever, the boys in the lab, or in this case Duncan McGregor‘s  multi-touch team have gone a step further and created a multi-touch ‘gesture’ library. This allows finger combinations to do groovy things like expand and reduce windows, pull up multiple windows in one workspace, and call up the ‘dash’ automatically. These are in 10.10. In 11.04 we will see a lot more.

Because there are a very limited number of touch-enabled devices out there at present, we thought we would create a video to show some of the features. You can see it below. It has turned out rather nicely even with the clumsy paws.

Afortunados sean los que utilizan Ubuntu y Android y no es por decir, en breve explicaré porqué =D. Primero me gustaría enseñaros que es Ubuntu One, es un sistema de sincronización en la nube que permite sincronizar archivos (como Dropbox), los contactos y los favoritos de Firefox. Tiene una versión gratuita de 2 Gb pero se puede tener paquetes de 20 Gb por 2,99$ al mes o 29,99$ al año.

¿Y qué tiene que ver esto con Android? Pues porque los chicos de Canonical han sacado un par de aplicaciones para Android  que permiten lo mencionado arriba. Una para sincronizar los contactos y la otra para llevar tu música contigo.

La aplicación que se encarga de sincronizar los contactos, Ubuntu One Contacts ya estaba desde hace tiempo y sólo hace eso, sincronizar los conactos. Para los más curiosos pueden ver el código fuente de la aplicación aquí.

Por otro lado tenemos la aplicación Ubuntu One Music recién lanzada con la nueva versión de Ubuntu, la 10.10 que incluye una tienda de música al estilo iTunes Ubuntu One Music Store). Con esta aplicación podremos escuchaar nuestra colección de música en streaming además de poder escucharla de froma offline. Para utilizar esta opción tienes 30 días de servicio gratuito que a partir de entonces costará unos $3.99. También con la aplicación podrás navegar por la tienda de música y comprar lo que necesites =D

Canonical is pleased to announce the release of uTouch 1.0, Ubuntu’s multi-touch and gesture stack. With Ubuntu 10.10 (the Maverick Meerkat), users and developers will have an end-to-end touch-screen framework — from the kernel all the way through to applications. Our multi-touch team has worked closely with the Linux kernel and X.org communities to improve drivers, add support for missing features, and participate in the touch advances being made in open source world. To complete the stack, we’ve created an open source gesture recognition engine and defined a gesture API that provides a means for applications to obtain and use gesture events from the uTouch gesture engine.

Our multi-touch work began in Ubuntu 10.04 LTS, when we worked to get additional touch hardware supported in the Linux kernel, particularly the Dell XT2, HP tx2 tablets and the Lenovo T410s laptops. With that in place, and active development in X well under way, we reviewed our options for gesture recognition in Linux. The Maverick cycle has seen us produce several prototypes for gesture recognition software and the Ubuntu archives now include the results of that effort.

The world’s expectations of software experience are being raised by advances in mobile computing. We are bringing that revolution to the Linux desktop: for window management and applications. Though our work at the application level has only just started, we are certain that multi-touch and gestures will be central to the way we use Linux applications in future.

The success of touch in applications depends on several key factors:

• toolkit integration of gesture APIs
• touch support for legacy applications
• designing new applications for finger-based interactions

Work has begun on all three fronts in Ubuntu, and we expect it to remain an area of active interest over the next few releases up to 12.04 LTS.

Ubuntu is the fruit of collaboration across the huge Ubuntu community, and also the amazing work of many other communities that form around individual projects and initiatives like Debian. The uTouch framework enables work to begin across many of those communities to make touch a first-class interaction model in open source desktop and mobile software.

Existing contributions in other projects have provided fertile ground for uTouch. To name just a few:

• Stéphane Chatty at ENAC has lead much multi-touch hardware support in the kernel
• Peter Hutterer at Red Hat defined multi-pointer X and proposed a multi-touch protocol for a future version of X
• Carlos Garnacho of the GNOME community has done multi-touch work in X and GTK

We’re look forward to continued collaboration, ensuring that Linux remains the preferred platform for people building cutting-edge devices and software.

Canonical is working with manufacturers of touch-enabled products and those of their underlying technology in order to bring innovations in user experience to a broader audience. Our aim is to bring the natural, tactile experience of the world to the desktop, window manager, and applications you value — all the software that you depend upon to get things done and have fun. Touch will be part of the Ubuntu Netbook, Desktop and Light products from 10.10 and beyond.

De GIMP (GNU Image Manipulation Program) poco tengo que comentar: Un programa de retoque fotográfico muy potente, de código libre y accesible a todos. Yo lo llamo cariñosamente “el Photoshop de los no-profesionales” ya que para la mayoría de los usos que un usuario normal le da a Photoshop, GIMP los cubre a las mil maravillas… y es Open Source!

Pues bien, muchos vídeos, tutoriales, demostraciones se pueden ver por la red estos días de las maravillas que incorpora la nuevas suite de Adobe, CS5, y una de las más sorprendentes puede ser el eliminado y retoque de elementos en una fotografía con sólo seleccionar el elemento en cuestión. Resynthesizer viene siendo esto mismo, seleccionamos el elemento que queremos eliminar… y magia! Desaparece recomponiéndonos la foto sin problemas (aunque siempre se nota un poquito, siempre dependerá de la foto, tamaño del objeto a eliminar…)

El modo de aplicar lo que Resynthesizer nos ofrece es muy simple:

1. Lanzamos GIMP
2. Cargamos la imagen
3. Seleccionamos lo que deseemos eliminar
4. Accedemos al menú: Filtro > Realzar [Enhance] > Smart remove selection…

No puede ser más sencillito. El plugin, de código fuente libre y disponible para todos en su página web, es de muy fácil instalación sobre todo para los usuarios de Ubuntu ya que se encuentra disponible en los repositorios oficiales de la distribución de Canonical:

sudo apt-get install gimp-resynthesizer

Para los que usen el sistema de las ventanas, disponen de un paquete preparado para su instalación en su página web con lo que… más simple imposible.

Información básica

• Plataforma: Linux/Windows
• Licencia: Open Source
• Precio: Gratuito.
• Enlace de descarga: Resynthesizer o en los repositorios de Ubuntu.
