I realised that the current fuse-lighting plan has the nice property that we only need one trigger glider (unlike the two in the speed demonoid). Delaying the trigger glider increases the distance to both of the faraway targets, and appropriately, the distance change for the further target is twice ...

Seems like there's some hidden expensive-and-ugly in the slow^2-ness of those "slow gliders from the side", which might make up for the expensive-and-ugly freeze-dried *WSSes (since there will only have to be a few *WSSes, not sure how many but it's not a lot). I haven't been able to find anything ...

As a corollary of that, though, the signal crossing that enables that feature will place some slightly annoying constraints on the single-channel stream. We'll have to add delays in the single-channel stream whenever a collision would otherwise happen -- might add five or ten percent to the length ...

Then maybe the next task is to figure out a reasonable switching system, for a regular single-channel construction arm to have room to send off that series of *WWSes, then have all future single-channel gliders pass through into a G-to-MWSS converter with 90-tick repeat time, that feeds MWSSes into...

If we're building a Speed Orthogonoid, we'll need two blinker puffers, because there's two faraway targets we need to make, right? Unfortunately I don't think there's some clever trick analogous to building a double crabstretcher like was done in the Speed Demonoid. I suppose you can join two blinke...

Wonderful! We can skip all that complicated Blockic-seed stuff, then, and just fire that slow *WSS salvo with a regular single-channel construction arm. Not sure if I'll have time to put together a compiler script for these salvos before mid-April or so, but somebody should certainly do that... the...

I want to try popseq.c but am unsure how it works as the relevant Tutorials part is not clear enough; apparently the original package does not contain any 4G collision database. Do I just compile it, feed it with the active pattern, and wait while the script automatically enumerates and tries all 4...

Looks like the bomb blinker fuse has some very promising options...Better options are no doubt out there somewhere, but this ash can be cleaned up into a safe target with at most four *WSSes -- six in all, including the two slow *WSSes in the above pattern -- so that's an upper bound to work on red...

I found a nice reaction for eater bridge eater from a post by Extrementhusiast from 2015 : x = 14, y = 14, rule = B3/S23 3b2o$3b2o3$b2o5b2o$obo4bo2bo$bo5bobo$8bo2$10b3o$9bo3bo$9bo3bo$9bo3bo$ 10b3o!

Just Need A Minimal Universal Block-Move and Block-Splitting Library This is actually something that it doesn't take an expert or a programmer to work on, necessarily. Something that would work would be to find a series of slow collisions of *WSSes with a block, that produce two well-separated bloc...

Technically "as close to orthogonal as possible" would be exactly orthogonal, right? Seems like Goldtiger997's SMOG might be a good place to start if that's the goal -- or rather (I think) to the RRO version of it . It's almost just a matter of adding a chirality-changer to the beginning of the rec...

New SKOPs (Smallest Known Oscillators of various Periods) Smaller oscillators for the periods 25, 32, 62, 74, 76, 96, 128, and 196 were discovered in 2021: #C p25 by iNoMed: https://conwaylife.com/forums/viewtopic.php?t=&p=133286#p133286 #C p32 by hotdogPi and praosylen: https://conwaylife.com/foru...

Efficient still-life syntheses: the 12-in-7 and 15-in-11 projects In 2021, many small still-lifes had their glider syntheses reduced. In particular, two projects were achieved: reducing the cost of all 12-bit still-lifes to below 8 gliders, and reducing the cost of all 15-bit still-lifes to below 1...

2021 spaceship syntheses A glider synthesis of edge-repair spaceship 1 was found (the fourth c/3 spaceship to be synthesised), and syntheses for 72P4H1V0 and 61P4H1V0 were also found (the second and third c/4 spaceships to be synthesised respectively). Furthermore, syntheses for an infinite family ...

Is Max synthesizable? I think so, but I'm just guessing really. We can't be sure until someone actually constructs a synthesis, but I suspect that will not happen for a while, because doing so seems like it will be very difficult. Max has quite a lot in common with the already synthesised Canada Gr...

So -- would anyone be interested in writing the Universal Shotgun Builder script we've all been waiting for, to build a period-N shotgun for any arbitrary salvo of unidirectional gliders that you might want to feed into it?

Regarding this post, I made a 2c/3 wire receiver with repeat time 964... Unfortunately, it isn't compatible with double signals. By "incompatible" does the user mean the following Snark heart cannot be welded to the wire?... No, all I meant was that if you place a double-signal instead of a signal-...

And here i need help. Let's construct a 4-Fireship-gun with a period of 864. With a p200-rake at its head and a Herschel-eater at its feet you get a growing Herschel-conduit (and a breeder) made only from Fireships and Blocks. I have no clue to build such a gun with Fireships so close to each other...
