I was messing around with using glider streams to cut through a field of junk, and discovered this:

x = 405, y = 398, rule = B3/S23

Life Hashing System:
-Each pattern has a binary number.
-Start at top left of bounding box. Go left to right, top to bottom (like reading).
-Example:0x0
00x
xxx is 010,001,111

-Patterns are oriented and filpped to have the lowest possible binary number.
-Oscilators and spaceships use phase ...

Yes please.

I'll send you a PM with my name and email address.

I will pay $50 to the first person who creates an internally steerable spaceship. It must meet these requirements:

-Contains one or more memory loops
-Uses the information in the loop(s) to turn the spaceship
-Does not require anything external to operate (I.e. no still lives, oscillators, gliders ...

Nice!

an 8-cell pattern with a glider and a blinker can last quite a while

Clearly the bounding box has to enter the equation along with cell count and lifespan (admittedly a tough if not impossible equation to come up with). I suppose there will always be trivial cases no matter what methuselah ...

I can't seem to get it to work for some reason.
PM 2Ring is using a very old version of Golly so some of his scripts don't work with newer versions (2.0 or later). Here is a fixed version:

# Modified for Golly 2.0+ by ...

Wow! Good Work Calcyman! It looks really cool! How do you use it?

In order to program the computer, you simply need to alter the sequence of eaters extending to the north-west.

Ok, I see.

Do you have a script to turn 1s and 0s into the eater sequence?

I discovered that a p30 Gosper Glider Gun can be used to invert a glider coming from the front:
x = 36, y = 24, rule = B3/S23

I was firing said gun into a debris field. A glider ...

p30 printer: update

This version comments out the setcursor() call, which fails on recent versions of Golly. It will also allow you to recover the uncompressed version of the compressed output script: simply run the output script at the command line instead of in Golly & the script will be ...

Incredible! I'll try and think of a use for this amazing discovery.


It could be modified to use a Herschel to bump a glider over. Is there ...

A Universal Constructor surrounded by a wall would need some way to detect damage and translate that into a repair.

Indeed. That's difficult, but theoretically possible.



It wouldn't be able to recover as fast as the incoming gliders could damage.

Again, I mean a device that can absorb all ...

Thank you. Is there a library of Herschel Conduits somewhere?

Good point. Dave Greene and I are making a pattern collection of stable technology, which includes Herschel conduits.


There are 22 elementary Herschel conduits, five of which use boojum reflectors.


Here are the remaining 17: (You ...

Thanks for posting that PM 2Ring! That helps me out too.

I strung together a chain of overwriters to create a repairable line of blocks. One of the gliders from each reaction triggers the next, with an extra block added to eat the other glider:

I just noticed that with this particle chaos field, one of Macbi's circles shows up in the middle at gen 382

After leaving it for a while, lots of the circles start to appear. I think for patterns like this, the whole inside of the octagon will always become filled with the circles and either ...

True, I do think it may be possible to make an pattern that can defend itself against any single glider ...

Thank you!

I don't know if anyone has mentioned adding HexLife (or whatever it ends up getting called). One of the difficulties with that one is that rotations are different.

I really like Golly.

Is there a way to rotate a selection 90 deg?

*snip*
There is no proof of a 100% eater, but I believe that a Universal Constructor surrounded by a wall could constitute such a pattern. However, Dave Greene seems to doubt this:

my instinct is that a stable pattern will never be 100% glider-proof -- there are too many possible lanes of attack ...

Thank you. Is there a library of Herschel Conduits somewhere?

I think the next thing I want to learn about is Herschel Tracks: How they work, how they're used, and what they can do.
