What does the "smarter scaling" option in Golly do? When you zoom out further than 1:1 the cells of the grid become smaller than the pixels of your screen, so each pixel corresponds to a square containing multiple cells. When smarter scaling is turned off then a pixel is coloured black if it ...

It can't just be large bounding box. Like long^5 barge has a large bounding box, but we've seen hundreds of them.

In Day and Night, "blobs" tend to form, and they slowly shrink down.
My question is, why do they shrink, and not grow?
If you zoom in far into a very large blob, it's almost indistinguishable what's the "inside" and what's the "outside". Day and Night is self-complementary, so they basically are ...

Could a superstring be inserted in this waveguide by gliders? You definitely can. x = 101, y = 106, rule = B3/S23

Just a question: Who voted most similarly to each other, and who voted most differently from each other?

I remember Macbi doing us such a search - it would be lovely to find out. Good idea.

Bellwether: wpolly

Macbi

As I did in previous years, I calculated the correlations between people's votes and the totals.

Bellwether: praosylen
Iconoclast: confocaloid

Most similar tastes: Hippo.69 and very (They both gave 5 stars to RCT15 and no stars to anything else.)
Most divergent tastes: C28 and Game of Life Fun ...

It seems like the most logical name would simply be 'transfer.cpp'. That distinguishes them while making it clear they're related.

Thanks, merged. (Version 6)

Macbi

Thanks. I'll merge that eventually but I'm a bit busy to do it right now. It would be faster if you could make a merge request in GitLab: https://gitlab.com/OscarCunningham/logic-life-search.

On Wire there's this claim about the zebra stripes wire: This wire must extend infinitely at the leading edge to avoid destruction, limiting its practical usefulness. Does this mean it's known impossible to get a signal out of the wire? Is the proof written down somewhere?

In dvgrn 's most recent NewLifeCA post he mentions that he will probably not write more posts soon, and that it would be better to use LifeWiki's 'In the news' section for updates. I'm wondering if it's possible for me to get an email when this section is updated?

Hi hollowme, it looks like both of these issues are about how LLS treats the edge of the pattern. By default LLS adds a row of empty cells around the entire pattern, so that no cell outside the original bounding box can become live. However I see that your 235 cell pattern produces some additional ...

Macbi

Yeah, it considers two patterns distinct if they have different evolutions or different rules. I see how this isn't the behaviour you want in this case. I'll add it to the todo list, but LLS isn't my priority at the moment.

Ah I see. I was thinking of 'rewindable' in the context of things like Gardens of Eden and the Grandfather problem, where the question is whether the pattern has any predecessors at all.

My friend Joseph Myers conducted arguably the most comprehensive study on tilings of polyominos, polyiamonds, and polyhexes:

Questions arise: besides the wick posted before and the lame ant fence pointed to by you, are there more examples of structures with that same behaviour ? I can't explicitly remember one, but in my experience they often arise from any fuse that burns orthogonally at c. Are there similar pattern ...

This reaction occurs for many fuses, and is known as the quadfuse.
