Concept videos of augmented reality gaming

Two of the things that I like most are games and technology. Projects that combine the two in innovative ways are incredibly interesting. What follows are a series of videos that show the augmented reality concept being applied to games, allowing tangible items to have an interface in a video game.

For more info, feel free to visit the augmented reality toys section of Frantz Lasorme's website.

His website also has a wonderful presentation about the merits of tangible toys versus video games (and the potential synergy between the two), which I will also embed here. If there is any interest, I will translate the slides to English:

A big shout-out to Frantz, who lives in Nantes, France, as I spent a semester in Nantes while I was in college, and I will always have a soft spot in my heart for the area. Votre technologie est vraiment formidable, Monsieur Lasorne. Bravo.

Ubuntu 10.04 Released! Get Downloading!

Today is the day! Ubuntu 10.04 LTS has been released!

For a list of features, check out the Ubuntu tour here.

A brief listing of changes (from xtemu.com):

GNOME
Ubuntu 10.04 LTS RC includes the latest GNOME desktop environment with a number of great new features.

Linux kernel 2.6.32
Ubuntu 10.04 LTS RC includes the 2.6.32-21.32 kernel based on 2.6.32.11.

KDE SC 4.4
Kubuntu 10.04 LTS RC features the new KDE SC 4.4. For more information about new features in Kubuntu, see the Kubuntu technical overview.

HAL removal
This release fully removes HAL from the boot process, making Ubuntu faster to boot and faster to resume from suspend.

Major new version of likewise-open
The likewise-open package, which provides Active Directory authentication and server support for Linux, has been updated to version 5.4. The package supports upgrades from both the officially supported versions 4.0 (Ubuntu 8.04 LTS) and 4.1 (Ubuntu 9.10), as well as the likewise-open5 packages from universe.
Since this upgrade involves a lot of configuration file changes and in-place database upgrades, testing and feedback is appreciated.


New default open source driver for nVidia hardware
The Nouveau video driver is now the default for nVidia hardware. This driver provides kernel mode setting, which will give improved resolution detection. This driver provides hardware accelerated 2D functionality, like the -nv driver it replaces. The nouveau driver is being actively developed upstream and we anticipate this will enable faster bug fixes for problems encountered.

Improved support for nVidia proprietary graphics drivers
Three different NVIDIA proprietary drivers are currently available: nvidia-current (190.53), nvidia-173, and nvidia-96. Thanks to a new alternatives system, it is now possible to install all three of these packages at the same time (although it is only possible to have one configured for use at a time).

Social from the Start
We now feature built-in integration with Twitter, identi.ca, Facebook, and other social networks with the MeMenu in the panel, which is built upon the Gwibber project, which has a completely new, more reliable backend built on top of desktopcouch. Gwibber now also supports a multi-column view for monitoring multiple feeds simultaneously.

New boot experience
Multiple changes to look, feel and speed of the boot experience have been included in the Ubuntu 10.04 LTS Release Candidate.

New Indicators
The notification area now features more consistent user experience and design for communication, session management, and many other tasks. See the application indicators page for information on this change.

New Themes
The desktop has been beautified with the addition of two brand new themes, Ambiance and Radiance. New wallpaper and icons are also included.

Ubuntu One File Syncing
Select any folder in your home directory for sync, pick from your existing contacts when sharing folders. An updated preferences application has been added, with more features.

Ubuntu One Music Store
Millions of songs are available for purchase from your Ubuntu desktop, integrated with the Rhythmbox Music Player and using Ubuntu One cloud storage for backup and easy sync.

New features for Ubuntu Enterprise Cloud (UEC)
The Ubuntu Enterprise Cloud installer has been vastly improved in order to support alternative installation topologies. UEC components are now automatically discovered and registered, including for complex topologies. Finally, UEC is now powered by Eucalyptus 1.6.2 codebase.

This release will probably be known as "the one with the buttons on the left", as the default window buttons are moved from the upper right to the upper left.

Of particular note is the Ubuntu One Music Store, an iTunes alternative, which is being released with this version of Ubuntu.

For free Ubuntu downloads, click here! C'mon now, get downloading!

For those that have already downloaded the "Lucid Lynx", there are already tweaking guides or updates scripts that have been published, such as this one at WebUpd8.org.

April NEWLUG presentation now online!

This month, the North East Wisconsin Linux Users Group has recorded the presentation portion of their monthly meeting. This video has been posted to blip.tv.
The subject for the month of April:
Solaris: History, background, and features.
Ivan will be talking about the OpenSolaris project this month. He'll discuss some of the history of how the project came about, covering some basic background on the project, and diving into many of the unique features that make it different and stand out from other operating systems.

Here are the slides from the presentation, courtesy of Slideshare:

Using ffmpeg to convert videos to FLV format

Linux has a wonderful tool called ffmpeg that makes video conversion easy....as long as you're OK with the command line.

Here is a sample command line argument that would help you convert to the FLV format:

ffmpeg -i input.mp4 -ar 22050 -ab 32 -f flv output.flv

Let's explain some of the operators in this command:

• "-i" indicates that the next word is the input file name (input.mp4)
• "-ar 22050" indicates an audio sampling rate of 22050 Hz
• "-ab 32" indicates that the audio bitrate is 32kbits/second
• "-f flv" indicates that we wish to convert the video to the FLV format
• You could also force the video to convert to a particular resultion with "-s 320x240"

This is useful for a service such as blip.tv, which automatically converts your files to flv format, but can occasionally have issues. For more info, check out the ffmpeg website. Have fun converting!

Pandora Console nub configuration video

Android successfully dual-booted on iPhone

Planetbeing recently posted a video showing a successful dual-boot of Android and the native iPhone OS on a first generation iPhone. His notes about the process can be found on the Linux on iPhone blog.

Without further ado, here is a video of the dual-booting phone, as well as several common tasks performed in the Android OS:
