Linux Voice Magazine – Open Sources Content after 9 months!

A new post over on the official Raspberry Pi blog features a new Linux magazine called Linux Voice. This mag has a couple of subtle differences to make it a bit more FOSS friendly.

Firstly, 50% of the profits will be invested back into the OSS community. The recipients will be chosen by the readers so it’s all kept fair.

Secondly, nine months after release, each issue and all content will be released under the Creative Commons Attribution ShareAlike Licence (CC BY-SA)

You can find out more (and grab a subscription) on their IndiGogo page but we agree with the Rasp Pi guys that this is a fantastic alternative to traditional publishing models.

Or you can wait 9 months and we’ll re post each issue as soon as the open licence kicks in!

You can get the “Wolfram Language” & “Mathematica” on Raspian, for free!

The Raspberry Pi Foundation and Wolfram research have teamed up to bring Mathematica to the Pi.

What is Mathematica? Well according to the official Matematica site:

Almost any workflow involves computing results, and that’s what Mathematica does—from building a hedge-fund trading website or publishing interactive engineering textbooks, to developing embedded image-recognition algorithms or teaching calculus.

Mathematica is renowned as the world’s ultimate application for computations. But it’s much more—it’s the only development platform fully integrating computation into complete workflows, moving you seamlessly from initial ideas all the way to deployed individual or enterprise solutions.

All future downloads of Raspian will include the software be default but you can get it now but running the following in an LXTerminal Window:

sudo apt-get update && sudo apt-get install wolfram-engine

It’s a pretty hefty download (some 600mb) so make sure you have enough space on your SD card and a bit of time for the packages to come down.

Turn your Raspberry Pi into a radio!

Some great work from the team at IC Robotics has turned the Pi into an FM radio! Capable of playing back wav files via a Python application (backed with a custom C library).

At the moment it’s Mono only and there are some issues with CPU priority but it’s a great starting point.

And there’s more, Guido PE1NNZ has released code to enable the Raspberry Pi computer board to generate SSB on the 7 and 14 MHz bands. SSB is used in HAM radio around the world and Guido has managed to make contact with other users across Europe via his Pi.
