After seven years, Apple open sources its Apple Lossless Audio Codec

Filed under

Apple first introduced its own lossless audio compression format, Apple Lossless Audio Codec (ALAC), in 2004 with iTunes 4.5. This Thursday—seven years later—the company made the code for its encoder and decoder available under an Apache 2.0 open source license.

ALAC is similar to another common open lossless format know as FLAC (Free Lossless Audio Codec), but uses an MPEG 4-compliant QuickTime container. ALAC is supported in iTunes as well as Apple's popular iPod and all iOS devices. For audiophiles who can't stand lossy formats like AAC or MP3, it offers a better sounding alternative.

Subuser uses Docker containers to deliver desktop apps for Linux

Distributing desktop applications for Linux has long been a headache, in large part because apps have to be repackaged for each Linux distribution. And while an app-containerization technology like Docker makes it easier to bundle and distribute apps, it wasn't really designed for distributing desktop applications. Subuser is a new application-packaging system that allows Dockerized desktop apps to be run as if they were regular Linux applications. It provides just enough permissions to allow the Dockerized app to interact with the local system -- for instance, to work with the X11 display server -- while still keeping it locked down.

Automotive Grade Linux wants to help open source your next car

There are times I wonder how the auto industry has managed to fall so far behind in the realm of technology. Only within the past year or so have we seen the rise of commercially available wireless options in mass production vehicles. Take a look at the standard options for mobile displays within car dashboards and you will see nothing to truly impress you. Consider that a low-spec smartphone is more impressive (and offers far more features and services) than does that console of a high-end automobile. Recently I rented a Jeep Cherokee Limited edition, that included a touch-screen console with what was supposed to have all the bells and whistles. That touch screen wound up to be less-than user-friendly, not even remotely yielding to what I what I wanted it to do, and served little purpose other than to navigate my wife and I through Miami, Florida, listen to music, and view the rear-facing camera for backing up. The in-console display had serious issues connecting to any smartphone we had, so music was limited to satellite. Read more

Red Hat rides the IoT wave with open-source

In the past, only companies with the deepest pockets were able to benefit from gathering data from distributed devices to drive better decision making and realize additional revenue. Today, the economics of the IoT architecture--the hardware, the ubiquitous nature of connectivity, big data and analysis, and customer expectations are dramatically expanding the scope of IoT and making it possible for every enterprise--and not just consumers--to benefit.
