Mathematica free on Raspberry Pi

Since November 2013. I can't imagine how I missed it. Has anybody played with this yet?

I was thinking this might be handy for number crunching sensor data we collect using the prop.

Is this bigger news than the Raspby Pi itself, or am I over reacting?

    it takes a while to do the apt-gets, (update, upgrade, and install) and then reading the instructions of cousre takes time. But so far it looks a LOT simpler than the other complex math packages that I never could figure out. In this case, the tool does not seem significantly more dfficult than the math.

    I also have to set up tightvnc as I am running RPI headless. I can't get HDMI to work on the crappy spare tv (maybe its a cheap HDMI cable) but I can use the fancy 4K monitor on the gaming rig. That seems to work so far.

    Time to play!

    Braino,

    I also have a crappy old monotor with only HDMI input that did not work with the Pi out of the box. Turned out the monitor was not returning its available mode information correctly, or at least the Pi did not understand it. I forget the details but a got it working by fetching the info out of the monitor manually with the "tvservice" command and then trying some of the modes it included in the config.txt file.

    You can find details on this here: http://elinux.org/RPiconfig

    :lol: Professor Braino, :lol:
    This is what I have been waiting for. I wonder if this will work for the
    Beaglebone? Do you think it can be ported?
    This is big news to people who need, it and have problems
    screaming to be solved!
    Thanks!:lol:

    Yes, I tried some of that, tvservice tells me its 1680x1050 so I forced those modes, but she still won't go. As I investigated, I kept running across "replaced cheap HDMI cable" as the fix. I've had issues with the less mainstrean monitors and recall the swapping cables thing. I think all my spares are those rejects. These came with the "roku" but we too short for the installation.

    Of course I will continue to screw around with it, but I think I will end up waiting until erco finds a deal on 100 HDMI cables for $0.78 each.

    Do I understand that VNC off loads the all the graphics and display stuff to the client, or is the RPi doing the same amount of work as if the monitor and keyboard were attached to the RPi?

    I think that linux is linux, and ought to work on anything, BUT the user agreement says "Mathematica on PI", and Wolfram is about a billion times smarter than me, and I make it a matter of policy to not mess with folks a billion times smarter than me. (except heater). On the other hand, the mathematica page free for educational, non commercial use. I didn't read the whole thing yet, just the big letters.

    That being said, I have several experiments in mind along those lines. Not that I would ever attempt to violate any legal stuff, I just want to test edge cases.
