I've been running that same B2a3i/S12 p3 search on another EC2 box, this one with ~64 GB RAM and ~2 TB of SSDs. It's only a fairly subjective feeling from reading the logs, but it seemed like it was merely "slow" into maybe the ~300-500 GB range and thus that the earlier tests with 8 GB RAM may have...

Gah, if only I had this 4c/8 dot spark (faked here by PASTET EVERY): #C [[ TRACK 0 -1/2 ]] x = 237, y = 174, rule = B3/S23 2bo231bo$b3o5b3o12bo5bo175bo5bo12b3o5b3o$2obo4bo2bo5b3o3b3o3b3o173b3o 3b3o3b3o5bo2bo4bob2o$3o4b3obo4bo2bo3bob2ob2obo173bob2ob2obo3bo2bo4bob 3o4b3o$3o2bo6bo3bo2bo4b3ob3o175b3ob3o...

Some time back I had been wondering if there was a rich world of 3c/4 signals (similar to the rich world of 2c/3 signals), but don't recall much success. IIRC I had found a few 3c/4 tails for still-life fuses, but that was about it. I started looking again but still couldn't find much at merely 3c/4...

Even more 3c/6 heartbreak, 8.5 Y rows of c/2 for blocks edge: x = 427, y = 21, rule = LifeHistory F.43BABABABABABABABABABABABABA.F70.F70.F70.F70.F70.F$F.40B2ABABABABAB ABABABABABABABABA.F.40B2ABABABABABABABABABABABABABA.F.40B2ABABABABABA BABABABABABABABA.F70.F70.F70.F$F.40BA2BABABABABABABABABABABABA...

((24, 12)c/72 "incremental" wickstretcher) Obviously it would be even more ridiculously large, but if you could repeatedly light the wick and stop it burning you could probably swing variable period puffers from this. I had sprayed random cells on the end and was idly watching it burn when I notice...

(about (2, 1)c/6 wickstretchers) Come to think of it, maybe you'd be able to even stretch a wick like this: x = 43, y = 84, rule = B3/S23 o$bo$2bo$3bo$4bo$5bo$6bo$3b3o$2bo$3bo$4bo$5bo$6bo$7bo$8bo$9bo$10bo$11b o$12bo$9b3o$8bo$9bo$10bo$11bo$12bo$13bo$14bo$15bo$16bo$17bo$18bo$15b3o $14bo$15bo$16bo$17b...

NW glider streams are just so very sad. Unfortunately, they are required for the second and third stages because those can't be both unidirectional and simple... I reworked the second stage, now it works at p72 but might be slightly more expensive : x = 228, y = 117, rule = LifeSuper 146.2C$145.C2....

But alas "a little poking in golly" and "simple kickbacks" is about the limit of what I know and I don't personally know how I could pack that SE salvo. I did eventually find some LWSS (W) + glider (NE) -> glider (SE) insertion but I couldn't get it to fit on either side. I finally completed the re...

Are there finite oscillators querying B7c, B8, S5e, S6c, S6e, S6k, S6n? While LLSSS could conceivably provide negative answers here, the first three I looked at all have positive answers, even just among p3 oscillators. S5e I had started with odd symmetry across the initial rows, like: | AABBBuuuCC...

In order to direct further researches, can you summarize the current state of the art of (2,1)c/6 technology, please ? The most important to know for synthesis optimisation would be: - known types of rakes (available directions, edge-shooting ones ...) - garbage deletion for small objects - glider ...

I was dreaming again of trying to make a (2, 1)c/6 wick stretcher for this wick: x = 43, y = 84, rule = B3/S23 o$bo$2bo$3bo$4bo$5bo$6bo$3b3o$2bo$3bo$4bo$5bo$6bo$7bo$8bo$9bo$10bo$11b o$12bo$9b3o$8bo$9bo$10bo$11bo$12bo$13bo$14bo$15bo$16bo$17bo$18bo$15b3o $14bo$15bo$16bo$17bo$18bo$19bo$20bo$21bo$22bo$2...

I was thinking about that horrible agarstretcher I had posted earlier and realized something like it could make a (2, 1)c/6 (higher period) "wickstretcher", but of course only for an ugly definition of wick: x = 202, y = 351, rule = B3/S23 35$38b2o$38b2o4$38bo$37bobo$36bo3bo$37b3o$35b2o3b2o11$38b2o...

Here's an idea for finding a period-7 3c/7 rake that might be feasible... ...you might be asking for "K-gram" edges... The most common problem with this sort of use is nothing forces the transition to actually happen and so your search may just keep on forever before the critical point. Indeed. I r...

Yes! Where do I sign up for that? Is there an API? Conceivably I could even have a script updating velocity tags on my posts automatically so I don't have to remember...

Most recently I wanted to find all posts of mine containing the string "(2, 1)c/5" but phpBB search is fixated on words of which that string contains none longer than one letter (which phpBB refuses to search). At least for something like 4c/8 I could filter for "4c" and read whatever showed up (inc...

Does anyone have an example of one vacuum-incompatible velocity dragging another? To rule out trivial examples I would probably demand they not be collinear and that both sides have their own bit of signal distinct from the wave-like signal joining them. ... I would also accept examples where the w...

(about c/4d catalysts for lighting fuses) Overnight (run to 8G) the most interesting thing that dropped out is probably this: x = 545, y = 24, rule = LifeHistory F33.F33.F33.F33.F33.F33.F33.F33.F33.F33.F33.F33.F.3BABA22B4.F.3BABA 22B4.F.3BABA22B4.F.3BABA22B4.F$F33.F33.F33.F33.F33.F33.F33.F33.F2.3BA...

I had been looking again at trying to use a 4c/8 pattern to solve the 2c/4 x 2c/1 sideways back problem (which would also allow level 4c/8 greyship backs). Definitely still work in progress but this fairly long partial I thought was worth posting: x = 395, y = 125, rule = B3/S23 ob391obo$obobo385bob...

It's simply a matter of finding a sparker that allows the glider to pass through cleanly.

I'm more a "make a giant, messy solution" sort of guy or maybe occasionally a "optimize one direction of clearance at the extreme expense of every other metric" sort of guy. What are you hoping to use a "reduce"d version of this in? I could try to optimize the NW clearance similar to the other spar...
