One thing I'd like to see would be Golly packaged as a flatpak to make it easier to install and update on most Linux distributions. However, I don't know if Golly's method of accessing text files for rules would clash with Flatpak's sandboxing.

May I have the trusted flag? My LifeWiki username is P46beth .

Okay, since I am dumb and can't figure it out: what is the syntax for defining non-outer-totalistic rules?

In Reliable cellular automata with self-organization , Peter Gacs proved the existence of a 1-dimensional cellular automaton which is computationally universal, and for which a universal computer can survive random perturbation if the error rate is sufficiently small. It's pretty complicated (it has ...

Isn't it "honeylife"?
Well, Dave appeared to be referencing this post:
In case they do not, how about: "Pedestrian Life" for B38/S23 (since traffic lights do not occur in this rule), "Pulsar Life" for B3/S238 (given the frequent pulsars from pi heptominoes), and "Honey Life" for B38/S238 (since ...

There was one run through this site awhile ago. It is no longer supported or being recorded.

Also, Matthew Cook's construction of universal computation in ECA rule 110 stores information as the distances between spaceships rather than the presence or absence of spaceships themselves, so that idea isn't new either.

I know the CellularAutomaton command in Mathematica supports arbitrary transition functions, including pseudorandom rules. It seems to be optimized for one-dimensional rules, and doesn't do very well displaying animations of 2d rules the way Golly can. You also can't get it for free.

The link to Calcyman's site appears broken...

Wait. You reminded me why I found Life fascinating in the first place. But I was just searching the wiki and realized... there are no replicators in life. At least, not in the wiki. There are replicators for high-life but not for life. Does anyone here have the seed for one? thx
There are no ...

I just realized something: OR gates cannot be synchronous. This means that unless if we can find a conditional 2-gen advancer to fix the problem, this rule will be inevitably worse than the original Wireworld.
I believe this is what you are looking for:
I already posted an OR gate above ...

This device will convert a p4 stream into a p8 stream, by deleting all electrons which follow another by 4 generations:

Yea...

the interesting thing about that device is that when switching the cell on, the electron will continue in a straight path unaffected, while when switching the cell off, it is destroyed. This can be used to make a very long period oscillator. For example:
x = 20, y = 20, rule = wireworldjvn2 ...

Here is a pattern which is simultaneously a switchable memory cell and a heisenburp. Specifically, an electron can switch the cell on or off without being effected! It can even loop around again. x = 15, y = 18, rule = wireworldjvn2

It can emulate an interesting class 3 rule:
x = 60, y = 60, rule = WireWorldjvn2:T60,60

I decided to modify normal wireworld to work in a JvN neighborhood. Initially, I kept all the rules otherwise the same:
# WireWorld JvN
#
# rules: 6
#
# Golly rule-table format.
# Each rule: C,U,R,D,L,C'
#
# Default for transitions not listed: no change
#
# Variables are bound within each ...

So, it appears we now have a working glider synthesis and a glider destruction for the snark. That should lower the size of the geminoid significantly.

But we already have two other threads with essentially the same purpose...

In Golly 2.5, please support neighborhoods with any 8 neighbors selected from the 24 nearest neighbor set?

This has been requested before, and I thought it turned out to be hard to add directly without slowing down the rest of the program...it is probably too late to add it ...

The following pseudo-period 20 rotor was found by extrementhusiast awhile ago:

Or accidental discoveries...

Indeed, the width 13 already has a bounding box with an area of only 221.

An interesting question: what is the smallest orthogonal spaceship (by some definition of "smallest") with speed lower than c/2? So far, by bounding box area, the leading contender is
x = 5, y = 16, rule = B3/S23

The (26+n):2n proof-of-concept, as knightlife says, is maybe "cheating a little and not entirely satisfying". I don't think it's cheating exactly,
I'm not sure why you are calling it a "proof-of-concept" when it works as presented and explicitly constructs a splitter with a glider to block ratio ...
