It’s all a matter of timing

Posted in Chapel, Elixir, Erlang, FORTH is it dead or isn't it?, Parallella on June 24, 2017 by asteriondaedalus

So, phew!

I re-bombed parabuntu onto the SD card.

What the problem was earlier was the security key had changed but I was forgetting to say YES to option for saving the new key (I had quite a lot of red wine last night so don’t be so hard on me 😉 )

When I powered up the Parallella again, I wasted no time and jumped in with:

sudo nano /etc/network/interfaces.d/eth0

---- inside of nano ---

auto eth0
iface eth0 inet static
address 192.168.0.150 // your parallella IP here
netmask 255.255.255.0 // your netmask here
gateway 192.168.0.1 // your gateway address here
dns-nameservers x.x.x.x //your dns server list here

--- exit and save ---

sudo reboot

Happily now running on the static IP set … phew!

Now to work.

Target environments will be erlang/elixir and chapel.  Yet, ePython for poking around.

I am reading back into my threaded interpretive days to look at a minimal FORTH runtime to run on the Epiphany.  There has been chatter on the parallella groups about J1, but that is a HDL (read FPGA) FORTH.  I think many people chattering haven’t worked in FORTH so much of the chatter is unproductive.  I am thinking a GForth running on the ARM side that assembles, rather than cross compiles, to a hand built threaded interpreter on the matrix.  I am not sure how feasible that all is but it will be  a good instrument for learning the nuts’n’bolts of Epiphany.

Many lessons can come from the struggle, yes?

This, idea is no more or less I worked on during a project, in Canada, where I noted the DSP software the team was using was already using a threaded processing chain.  The idea then of control loops and conditional inside of that was a soft sell.

So, in FORTHeze no outer interpreter running on the Epiphany.

New way to stuff erlang/elixir onto embedded arm

YES, it is “designed” for RaspingBreathberryDoodlePi BUT worked a treat for OPiZ.
