This has nothing to do with Life, so it's not appropriate here. Spam is also against this site's terms of service.

[hkoenig]

I was impressed by how the user had registered months ago, and this was its first posting. Usually spammers don't wait that long.

[hotdogPi]

And if you actually looked at what all the websites were, they were horrible. Many of them were .us.com, and there was a [something]uk.uk.com somewhere in there. The worst, however, was officialyeezywebsite[dot]us[dot]com. Does anyone seriously think that's Yeezy's actual website?

[dvgrn]

I suppose you all are welcome to answer spammers or talk about spam if you really want to, but it seems to me that it mostly just causes confusion and/or leftover off-topic clutter when the originals disappear. If everyone is just a little bit patient, spam will continue to just silently melt away.

I suspect, that all Glider-collisions with 3 are discovered.
Nevertheless:

Code: Select all

x = 9, y = 13, rule = B3/S23

Just for the record, synthesise-patt.py does come up with exactly one matching recipe --

Code: Select all

x = 8, y = 11, rule = B3/S23
bo$2b2o$b2o$6bo$5b2o$5bobo3$2o$obo$o!

-- when you feed in that collision starting from the collision point. It's not quite a foregone conclusion that any 3G collision like this one will be in the synthesise-patt database, but the odds are certainly very good. Looks like there are something over a thousand 3G -> G collisions in the database, though it's a bit difficult to count accurately since half of the 2485 results for a plain glider are actually boat syntheses -- an artifact of synthesise-patt's use of population as its hash function.

This particular recipe is a tee reaction, which might be handy because the two parallel gliders are unusually far apart... the sizable silly southward spark might be a bad thing or a good thing, I guess, depending on the use.

[Jormungant]

There is this nice p3 180 reflector floating around, which seemingly can be used to make true period guns, I tried to make it work for p4, though I am not sure if there is a better solution hidden already hidden in the forums, since I have no clue when that reaction was first noted:

Code: Select all

x = 64, y = 45, rule = LifeHistory
