That works. Unfortunately it also results in Golly freezing after a Python script is run.
Just to double-check, what is the name of the Python installer executable that you used to install Python 3.9?

Re: Gun Discussion Thread

p29 domino sparker needed for p29 gun... This is not at all my area of expertise, but wouldn't you need a horribly unlikely domino sparker, to sneak in behind the outgoing glider fast enough? It seems like both cells have to turn on simultaneously, so the only predecessors I was able come up with o...

Re: Speed Demonoid

I downloaded Python 3.9 with Golly 4.0, and the error is still showing up. What path should I enter? First make sure that the Python 3.9 that you've downloaded is 64-bit Python -- the installer executable should end with "-amd64", I believe. It looks like python.org is finally linking to a 64-bit i...

Lua script, please!
Lua can't pull up arbitrary Internet URLs as easily as Python can. I suppose you could write out a local HTML file, then open it in Golly, and then have the user click the link -- but nobody has taken the time yet to put together that particular variant of biggiemac's script.

Re: The Hunting of the Elementary Conduits

Even if one follows it with a dependent conduit with that transparent block, there is ample space to delete the glider with a fishhook or sidesnagger. Is there any particular reason why the unnecessary still lives were there, or should I remove them? There's a very minor reason. As calcyman mention...

That means we have two elementary knightships now, and one extensible one. Great job calcyman!

Does that count as a new Knightwave then? Sure -- a ridiculously complex knightwave compared to the other one, but I guess it's still a knightwave. It can be thought of as traveling obliquely at (2,1)c/6, orthogonally at 44c/357, diagonally at 88c/807, or lots of other weird oblique velocities. x =...

Re: How about a direct highway robber?

It's kind of odd that we don't have a small highway robber yet--a p1 pattern that acts as a glider eater on one lane, but lets gliders pass completely on an adjacent lane and all further-away lanes. That description doesn't quite line up with my idea of " highway robber ". A highway robber has to b...
