I made a quick push to github. If I missed anything or you can see any mistakes then let me know.
Love the guns with MWSS trick :)

Re: Execution of Old Guns by Variable-Speed Firing Squad
2 rows from the p55--one from the shorter p110 stabilization, and one from replacing a p11 sparker with an eater3 shell to get the space to move the Herschel track closer. The eater 3 shell can be replaced by a known but little-used catalyst to save another column: With that optimisation it looks l...

Re: 18-bit SL Syntheses (100% Complete!)
The advantage of doing this is it makes these '16 in 16' projects easier to organise: Catagolue arranges objects in each tabulation in descending order of synthesis cost, so you can visually see which objects are currently the costliest. Indeed, according to Catagolue every 16-bit still-life can be...

Re: Shinjuku: a database of glider syntheses
Sounds great. Being based on lifelib means this will be much more suitable for running on some kind of automated server than my version. I had a brief look through the code and ran a couple of examples. I note that you are not detecting invalid syntheses yet. Example: >>> gliderset.gset.extract(lt.p...

Re: Execution of Old Guns by Variable-Speed Firing Squad
Sure, that works just as well... except for my continuing ambition to keep an updated collection of all the guns in the p14-p1024 range. A p366osc3 variable gun is trivial to add to the gun-builder template collection, but if the README just magically predicts smaller guns for certain periods of ex...

Re: Execution of Old Guns by Variable-Speed Firing Squad
A number of "osc7" variable guns use a suboptimal p7 bumper. Here are some corrections Thanks for these. Some of these periods are multiples of 3, so can unfortunately be reduced with the p3 eater trick: Thanks. I also found a few other guns with p3 bumpers. e.g. p381, p423 and p519. Most periods a...

Re: Small Four-Digit Prime Period Guns
I don't think this about the base loop size because you get the exact same crash no matter what the base size. More this is about the sequence of the gliders I think. Just adding a single block to your pattern to destroy the first glider from the Herschel at top-middle allows the gun to function as...

Re: Small Four-Digit Prime Period Guns
That would be the p392 I think...Although the channel where the glider is travelling SW already looks quite crowded and so tough to put a reset mechanism in there. Seems easy enough to widen out the p392 until a reset mechanism will fit. It turns out surprisingly well with a p532+8N base loop. Here...

Re: Small Four-Digit Prime Period Guns
Simpler Still? Seems like there's one possible adjustment that would allow a big simplification to the arithmetic of these things, if not necessarily to the size. If the base loop had an 8N period, then it would stop mattering what the multipliers were -- you'd still end up with 8N+k guns with the ...

Re: Small Four-Digit Prime Period Guns
Here is a period 2754 gun based on Jormungant's p941 (different components in the reset circuitry but roughly the same idea). As an even period gun I guess it is not hard to beat this area. However, I want to examine the period of this gun as we vary the lengths of the loops. Hopefully this will giv...

Speaking of automated gun-building, though, how difficult would it be to generate a one-off README for periods from 1025-9999, using your collection's variable guns? Here is 1025-4999: 1025 (7344, 'p00559x5_7') 1026 (6300, 'p00441x2_9') 1027 (7688, 'p00867_20') 1028 (4644, 'p00482x2_4') 1029 (6006,...

Re: Execution of Old Guns by Variable-Speed Firing Squad
What about adding guns for each prime number up to 5000, as period multipliers wouldn't work? It will probably involve taking the same basic gun mechanism and adding more and more snarks to keep the overall area as rectangular as possible. For example, here are p363, p571 and p827 guns which are th...

Bullet's p10 sparker can form a smaller stabilization for the p50 gun, replacing the previous bulky p30 blinker-pushing mechanism. This leads to new smaller p50, p100, and p200 guns: Nice!
