"Collision" is not the same thing as "Interaction". Those two gliders could not have possibly reached their places from infinity. Thus they are not of interest.

Re: Thread for basic questions
I have a question.
There are many adjustable spaceships and oscillators we discovered.
But, What if adjustable replicators? Is it possible? Or is it have already discovered?
Edit : IT IS SO CLOSE!!!!!

Re: Thread for basic questions
Only indirectly:
1) You need to supply your own computer to run apgsearch on
2) You need to provide electricity to run the computer
3) You need to provide an internet connection, and bandwidth to upload results
Re: Thread for basic questions
No, it won't. Running Catagolue costs money because it is hosted on Google App Engine. When you run it locally it runs on your own machine and the only cost is the electricity bill.
[Edit: ninja'd]
Regarding 3) - you would actually save bandwidth running Catgolue locally if you upload apgsearch results to your local instance of Catagolue (requires code modification of apgsearch).
The 5S project (Smallest Spaceships Supporting Specific Speeds) is now maintained by AforAmpere. The latest collection is hosted on GitHub and contains well over 1,000,000 spaceships.

Re: Thread for basic questions
Cool, I finally have somewhere to upload my 1x256X2+1 search results. Note: I know it's marked as a troll symmetry, but I had no intention of trolling with it.
Another question. Whenever I try to create a glider synthesis, what I'll do is pop it into JLS, and try to trace its evolution backwards into something that I can synthesize. It works for around 3 to 5 generations or so, but then I start running into problems. JLS starts to take huge amounts of time to reverse the evolution farther back, and whenever it finds something, it's usually some sparse cloud that would probably be harder to synthesize. Even population constraints sometimes aren't enough to stop this from happening. How can I work around this problem?
EDIT: Thanks Calcyman!

Re: Thread for basic questions
I've removed it from the troll symmetry list in the latest commit to Catagolue.
The reason for adding it to the troll symmetry list ab initio was that you made a lot of noise on many distinct forum threads. That, together with the other things referenced in my rant, drove me to the point of trollifying that symmetry.
As you've significantly improved in the three years since I made that post, you've regained the privilege of having 1x256X2+1 in the visible Catagolue.

Can this be made into a tiny P18?
Note that a W-pentomino with a single extra cell (disconnected from the pentomino) becomes another R-pentomino in exactly the right position. If we can get a P2, P3, P6, or P9 to provide that extra cell without destroying the rest of the pattern, we have a P18.

Re: Thread for basic questions
I guess I'd call it a well-known method, along with truncating the back end of spaceship search result lists.
Soup searching is how codeholic found the non-trivial fuse that completed the pufferfish spaceship, for example.

Re: Thread for basic questions
Is there any pi eater that has similar good clearance to Gosper's 2-block pi-eater, but eats it faster? There's mentions of other pi eaters on the forums every so often, but it tends to be in the context of conduits that use space all around the pi.
I have a glider collision setup that generates Pi's, and most of the eaters available that I've stumbled upon would get hit by the gliders on the way in. I'd love something like Tanner's pi catcher but just a couple cells less wide. For example, putting a tub right next to a pi turns it into a honeycomb, so, some catalyst or sparker that turns a honeycomb back into a tub should do the trick.

Re: Thread for basic questions
2 questions here.
1: Why do you need 8 gliders to destroy the block in the Snarkmaker recipe? Surely it's well-known how to destroy a block with one glider.
2: How do I find billiard table oscillators? I was able to rediscover known ones (including a P17 from jslife) from the shape of the walls, but when I hollowed out a random still life and tried to get a billiard table, I couldn't find anything. Help?

Re: Thread for basic questions
This question is about the "8 gliders to remove the 0-degree elbow when it's no longer needed" list item in the Snarkmaker article, right?
There's a big extra limitation when you're creating a Snark with a single-channel salvo. All the gliders are on the same lane, and only the timing can be adjusted. One glider hitting the block on that particular lane will make a pi-heptomino explosion. So instead we have to find a combination of gliders following behind each other on that lane, that settles the pi explosion and cleans everything up.
Eight gliders is as cheap as we can get it, I think, at least until we invent some new universal signal circuitry that recovers quicker than 90 ticks.
