    Played with a friend on a sandy area with some trees, it was great fun and requires no maintenance.
    I am not a golfer, we used a mini golf club and golf balls i found near actual golf clubs.



  • Rust has monomorphisation like C++ and every function has the aliasing guarantees of restrict, a keyword rarely seen in C code bases use and C++ doesn’t even support.
    This means you can get more optimisations while writing in an intuitive style, where C/C++ requires some changes to the code.

    On the other hand rustc has some hiccups with argument passing and rvo. One could argue that that’s just the compiler while the aliasing problems are part of the language in the C/C++ case, but while there is only one rust compiler its performance is the languages performance.

    For most use cases they are about equally fast.

    Because the tree would need to grow 100x as big. People often forget, that the carbon needs to go somewhere and in a tree that is mostly the wood.
    A fully grown forest is just full and can’t take up more CO2 unless you take some wood out. That wood need to be used in construction or turned into charcoal and buried to make sure it can’t be turned back into CO2 by rotting.

    In theory that means that one entire “floor” of the Luna is accessible, compared to just the vestibules on the traditional double-decker.

    In most double deckers in Germany you enter on the lower floor between the stairs and the bike space (foldable chairs and rails to strap bike to) and the stairs. Between the bike spaces is a regular sitting area separated by doors. A third up the stairs is the connection to the next cart and sometimes the toilet (some models have a accessible toilet on the ground floor), then the stairs double back for the upper sitting area.

    The sleepers trains had cabins with bunk beds, making the lower ones accessible. The proposed sleeper trains have stairs to each “pod” and a very narrow corridor.
    If they want to go double decker they should retrofit normal ones with beds, maybe two on top of each other on the bottom floor, and one on the top floor at higher cost.




  • Here is Berlins (pop. 3.7 mil.) metro and rapid transit train network:
    1000011525 Remarkably similar design, a ring route with routes coming out in all directions. In Berlin the rapid transit trains are more focused in the middle and only really diverge at the ring with metros covering most of the space. While in Chengdu the trains don’t share a rail, (except for the airport service) and have longer branch lines. The regional trains (thin red lines on the map) in Berlin go through the center similar to the rapid transit and make a few stops along some of the branch lines and the high speed rail only stops at the main station and one major station in each cardinal direction (marked with the train in a yellow circle).

    Also here is the tram network, it’s mostly east Berlin (guess when the other half was demolished), but slowly branching out into the west:
