Two questions (and a lot of subquestions :V ): First, is there any value in feeding apgsearch more memory to increase efficiency anywhere? (and if so, would it be a possible command line switch?)

You can download /textcensus/b3s23/synthesis-costs (21 megabytes) and then filter through that yourself.

Why are there two p2s called "beacon on something" and ":D"?
"something" was imported from an older census, and ":D" was Calcyman's idea of a joke.
I don't think it was my idea; I copied it from an anonymous comment someone made on the page.

I believe this prevents ikpx2 from advancing to a new width, since i think ikpx2 will always find a new (repetitive) tail piece which can be attached. A maximum length option would be helpful in such a case. This shouldn't happen: ikpx2 stores the entire search progress in memory to avoid ever perf...

Difficulty table works like planed economy, it would be better let the market decide price of each type of object. when profit is enough, miners would not waste any potential interesting soups.

Re: Soup-search based PoW mechanism ( using of messless)

Using messless as a proof-of-work would have the problem that people would discard a soup as soon as it has an escaping glider, and therefore miss lots of discoveries that would have been found by running those soups to completion. So, even if we had a multi-billion-dollar cryptocurrency, we'd be un...

Re: How about a unidimensional spaceship?

Yes, the blinkers that are already there form the instruction tape. It's translated by 2 cells to the right by this reaction (which will be the velocity of the spaceship). You can't move your blinkers and burn them too. The blinkers in the (very very long) tape are different from the blinkers in th...

Uh, this is cool and all, but how do you plan to put back the blinkers? There needs to be a copy of the instruction tape somewhere.

Re: How about a unidimensional spaceship?

It looks like forward HWSS-creating reaction might be sufficient for initial construction. The reaction can be used to create an arbitrary stream of single-channel monoparity HWSSes. The stream can then be aimed at a blinker elbow (or elbows) to (hopefully) provide universal construction. Here is a...
