    After much time has passed:

    i read somewhere that a japh is supposed to fit on 4 lines or less. Hmmm, i didn't know that when i first posted this. In deference to the rules, here is an updated version. The output has changed tremendously, and is now only useful if piped to a file :(

    #!/usr/local/bin/perl ($j,$a,$p,@h)=($ARGV[0]||68,-1,1,1,2);for(;$j>@h;){$==1;$a++;do{do{$;= +1;$_==$ p&&next,($*=$=**2+$=+$h[$a])%$_ or$;=0,$_**2>$*-1&&last for@h;$;}?@h=s +ort{$a <=>$b}keys%{{map{$_,1}@h,$=**2+$=+$h[$a]}}:8}while++$=<$h[$a]-1}shift@ +h;print !@ARGV?map{chr}$h[23]+$h[6],$h[24],$h[2]+$h[27],$h[1]+$h[25]:(map$_.$/ +,@h),$/

[stevieb]: choroba my GPS home device is done, at least prototype v1 is. I'm just making sure all of my code does what it says now
[stevieb]: I test/prototype code on my Pi, then I migrate it over to Arduino when it's ready (if that's a better platform for what I'm doing). The whole RPi stuff was for learning at first, then it snowballed. I'm just trying to get my in-house CI...
[stevieb]: ...done, which obviously requires a specific hardware setup.
[stevieb]: I don't write tests for the lower-level distributions (ie. ICs, sensors etc) within those distributions, I have all tests in a master distribution which encompasess all of the sub-modules
