Hey, the livestream chat cut off without me doing anything!
Unless it was just moving the fogging mouse out of the the youtube browswer window..
Andrew
@walpolea
maybe timed
Dave Ackley
@DaveAckley
I guess there must just be a limited time -
yeah
would be neat to see the MFMFont on a plate
as a new display
Dave Ackley
@DaveAckley
Can it be formatted as a BDF font? That's what my scripts ingest.
Andrew
@walpolea
no it's just event window coordinates
Dave Ackley
@DaveAckley
Ah, a different route..
Well, as ulam then, I guess.
positive and negative mean foreground and background?
Andrew
@walpolea
yes

if you plop down a READER on mfm.rocks and type slowly it will spit out characters to the left

I remember seeing the font but never looked at javascript..

@walpolea
each atom of each letter knows it's mapping so it can regenerate itself
Dave Ackley
@DaveAckley
For sure!

Hello @DaveAckley , great last T2sday update despite the technical issues! SIGH definitely seems like a very interesting concept, is there somewhere I can find your article PDF?
Dave Ackley
@DaveAckley
Hi @BenCrulis ! Thanks for checking it out!
Andrew
@walpolea
this talk mentioned in the stream chat is pretty good and relevant for sure https://www.youtube.com/watch?v=O3tVctB_VSU
this link shows the slides: https://www.youtube.com/watch?v=HB5TrK7A4pI

I'm looking for an online version of anything officially SIGH.. But so far not finding much.
I thought "A connectionist algorithm for genetic search" might be online but not finding it.
Ben
@BenCrulis
I see, well I will probably go back and watch your two videos to understand anyways. Would you say that this method is kind of transforming the problem from discrete to continuous space?
Dave Ackley
@DaveAckley
Have to see what I can come up with (other than the actual book, which is mucho bucks).
Hmm google shopping says Barnes and Noble claims its selling it in paperback for $24.99. I've never heard of a paperback edition though, probably bogus.
Let me see what I can find.
Ben
@BenCrulis
Okay, but don't bother too much!

Any thoughts on this? Is huegene a CA?
My initial thought is: Yes. But maybe I'm wrong!
(I wouldn't want to get too bogged down in semantics though)
Dave Ackley
@DaveAckley
It depends on what definitions people choose. I say yes, just like I say Langton's Ant is a cellular automata even though it is usually envisioned as an 'agent' moving around a grid.
Once people accept asynchronous updates as 'legal' for a cellular automata, there's no really crisp distinction between a CA and a spatialized ABM.
Luke Wilson
@l2wilson94
Thanks!

@BenCrulis
I like to think of CAs as grid based simulations with a locality constraint on the update rules. I don't know the mathematical definition though.
So, Wolfram physics project would not be a CA according to this definition even though you have locality, since it is not grid based for instance. But maybe it should be considered a CA
But I don't think determinism is important in the definition
Luke Wilson
@l2wilson94
Yes that sounds right!

Righteous scaling (same B/W chip to chip even in different cabinets!). Love 1.25M SRAM per chip. Wish for 6 or 8-way cxn instead of checkerboard geometry -- they're still on our 'T1 tile' approach.
Ben
@BenCrulis
I don't think it is really 'indefinitely' scalable, at least in their current software, but I may be wrong. Also I can't find a price range for this thing.
Andrew
@walpolea
pretty cool. not indefinite with the IO being the border around the grid.

Hi there everyone, happy t2sday!! It's been some time.. Trying to catch up on the updates (and streams!?) Also dusting off the 3d printer..

Hi @ajzaff !!!
