This week's featured article Parallel half-baked knightship or Parallel HBK is a knightship based on the well-known half-bakery reaction with a glider, and an improvement over the original half-baked knightship. There are several significant differences in design between the original half-baked knightship and Chris Cain's smaller version. The slow-salvo constructions are done serially in Goucher's design, and an extra glider is used to suppress the salvo that triggers the half-bakery trails. On January 3, 2015 Chris Cain built a HBK gun, that can run in Golly in reasonable time. The gun's design implies an easy synthesis with 57,286 gliders, though this is considerably larger than an earlier 38,380-glider synthesis by Michael Simkin. Read more... In the news July 29: Goldtiger997 constructs a fast diagonal Demonoid puffer with velocity (4825784,4825784)c/45679544. July 21: Adam P. Goucher reduces the cost of the reverse caber-tosser constructor to 32 gliders. July 20: A for awesome completes a new stable L122 Herschel conduit, based on a P2 periodic variant by Entity Valkyrie. July 18: A glider synthesis of 70P2H1V0.1 is posted to Catagolue by Martin Grant, making 70P2H1V0.1 the first period-2 spaceship to be synthesized. July 7: Goldtiger997 completes a record-breaking seed constellation that, when triggered by a single gliders, turn into a clean 100-glider recipe for a c/5 spaceship, 58P5H1V1. This potentially improves the unreachable upper bound on Demonoid speed from c/12 to c/5. July 1: A collaborative effort results in a series of HWSS Heisenburp circuits much smaller than the previous best known devices. Recovery time is under 1400 ticks. Some versions can also detect flotillas with an HWSS along one edge.

Did you know... ... that after ten years with no new small spaceship syntheses, a glider construction was found for the c/7 loafer in 2013 less than three hours after its discovery? ... that glider constructions for three previously inconstructible spaceships (the dart, the crab, and the Parallel HBK) were discovered in 2014? ... that glider constructions for the B29, X66, half-X66 with HWSS, Pushalong 1, 25P3H1V0.1, 30P5H2V0, 30P4H2V0.4, a pufferfish spaceship, and the weekender were discovered in 2015 — after fifteen years of intermittent efforts in the case of the weekender? ... that since 2014, more new spaceship syntheses have been completed than were found in all the years between 1970 and 2013? ... that as of 19 July 2020 there are 232 different still lifes known to be constructible by colliding four gliders, but it is likely that this list is not complete? ... that in 2014 a new natural infinite growth pattern was discovered, starting from a symmetric random starting configuration? ... that the first self-constructing Conway's Life pattern was built in 2010? ... that the first glider synthesis for a c/3 spaceship was completed in 2014? ... that the first "macro-spaceship" gun (a Gemini spaceship gun) was constructed in 2010, followed by the HBK gun in January 2015 and a Demonoid gun in December 2015? ... that the waterbear was the first known high-speed oblique spaceship, many orders of magnitude faster than Gemini spaceships and half-baked knightships?           Showing 10 items out of 114 More did you know...
