2024-11-20 10:20:00 <TactfulCitrus> lilo_booter: Okay now I've started watching a series on vacuum tubes when I should be doing some work ...

2024-11-20 10:47:33 <lilo_booter > TactfulCitrus: enjoy :D - he's a nice chap and does lots of happy dances when things actually start working
2024-11-20 10:47:58 <lilo_booter > .. i can relate
2024-11-20 11:08:03 <TactfulCitrus> I can also relate to the happy dancing!
2024-11-20 11:10:53 <lilo_booter > :D
2024-11-20 15:06:50 <xentrac     > a newish Forth?  https://hackaday.com/2024/11/15/risc-v-pushes-400-million-forth-words-per-second/
2024-11-20 15:07:37 <xentrac     > that's not the original Forth code.  it's the original ChipWits Forth code.  the original Forth code is https://github.com/monsonite/1968-FORTH
2024-11-20 15:15:02 <xentrac     > oh, apparently the Forths running on the MILK-V in the video are Pygmy Forth and Mecrisp
2024-11-20 17:27:04 <TactfulCitrus> General question, if i'm storing matricies in arrays would it be bad practice to store the data as [M, N, data, ... ] where M and N are the numbers of rows and columns the matrix has followed by the actual data or would I be better off handling those separately?
2024-11-20 17:37:28 <zelgomer    > i don't see anything wrong with that
2024-11-20 17:38:25 <zelgomer    > if for some reason you want to pass an address around that you can treat directly as data, you could even store M and N at negative indices
2024-11-20 17:39:10 <TactfulCitrus> What do you mean by that? Sorry very new to Forth
2024-11-20 17:39:50 <GeDaMo      > M N data, ...
2024-11-20 17:39:50 <GeDaMo      >     ^ pointer
2024-11-20 17:40:00 <TactfulCitrus> Ah I get you!
2024-11-20 17:40:06 <TactfulCitrus> Thanks very much
2024-11-20 22:33:05 <KipIngram   > TactfulCitrus: I once toyed with that idea for storing strings (and had a null at the end, as well as a count byte one byte back from the pointer).  The idea of course was to be able to treat it either way.   But after playing with it a bit I gave it up - decided it really wasn't beneficial.  In certain instances I do still put a null byte after a counted string, but I point to the count byte.
2024-11-20 22:33:45 <KipIngram   > What are your matrices representing?  Long term I'm interested in scientific computing, which will involve matrices; just curious.
2024-11-20 22:39:28 <MrMobius    > I've been working on a tiny subset of python I can run on a microcontroller and ran into this recently. to economize on RAM, I store the starting point and length of a symbol (function or variable name, keyword, etc) but then need a way to compare that to known symbol names which are zero terminated. to save space, there's just one strcmp that works with either format
2024-11-20 22:43:42 <xentrac     > TactfulCitrus: I'd recommend [rowstride, rowlength, colstride, collength, pointer] so you can transpose without copying

ACTION is one step closer to implementing line drawing - implemented cohen sutherland's line clipping algorithm :) - bresenham tomorrow

2024-11-20 23:24:50 <xentrac     > nice!
