Show HN: Pipes puzzle (a.k.a. Net) on a hexagonal grid Hello, HN - I wanted to share this puzzle game I made during my vacation. I'm rather fond of the pipes puzzle where your goal is to restore a scrambled network of connections by rotating tiles. It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So I did just that =). I find hexagonal pipes a bit more difficult than the square variant because there's a larger variety of possible tile shapes. For an extra challenge I implemented wrap mode where the board can connect to itself (right to left and top to bottom), so there are no convenient outer walls to start from. The site is made with Svelte Kit, its code is available on github at < https://github.com/gereleth/hexapipes >. Hope you enjoy playing =). https://ift.tt/pXtjyLJ July 25, 2022 at 12:50AM
Women Pioneers at Muni: Adeline Svendsen and Muni’s First Newsletter By Jeremy Menzies To close out Women’s History Month, here’s a look back at one woman whose work to bring Muni staff together in the late 1940s created a legacy that lives on to this day. Adeline “Addy” Svendsen was founding editor of Muni’s first internal newsletter, “ Trolley Topics .” Adeline Svendsen sits at her desk in the Geneva Carhouse office building in this 1949 shot. Trolley Topics was a new venture when it started in February 1946. As Svendsen wrote in the first issue it was created, “to bring a little fun, a little news, and a lot of good will to all our fellow employees in the Railway.” Just two years prior in 1944, Muni merged with the Market Street Railway Company, expanding the small municipal operation into the largest transit provider in the city with hundreds of employees, vehicles of every shape and size, and dozens of facilities scattered across town. The newsletter was meant to help unite ...
