      I like this puzzle although I think the colour framing adds a hole that needs closing: The players need to be told the set of possible hat colours for this to be solvable.

      One thing that struck me about the puzzle when I first encountered it is that it’s hard, as a human, to think of even one solution, but (edit: this is rot13 to avoid spoiling the puzzle for you) gurer ner n ybg bs qvfgvapg fbyhgvbaf gb pubbfr sebz sbe ernfbanoyr a.

        the colour framing adds a hole that needs closing: The players need to be told the set of possible hat colours for this to be solvable.

        I agree with this. At the time of writing I assumed most would make the jump from thinking in colors to assigning colors to numbers so I deemed that listing possible colors was an unnecessary detail. On second thought though it does add a nice level of completeness to the description. Thank you!

            Where I’m from it’s common courtesy to rot13 information that could be considered spoilery

            1. 2

              Adding to that, rot13 is used because it’s symmetric. You use the same key to encrypt and decrypt.

              1. 1

                If it weren’t for the fact that Garbi understood and responded the way they did, I would’ve simply assumed you’d had a stroke. You might want to at least preface your encrypted message with how to decrypt it.

            Working on a blog post for doing shape typing on numpy ndarrays

            1. 1

              The top use case of Nix for myself and coworkers is trying out new software via nix-shell.

              Being able run and share commands like nix-shell -p simplescreenrecorder --command "simplescreenrecorder" and not have to worry about anything else is pretty sweet.

              1. 5

                You might like nix run, which uses Flakes and “apps” to simplify that a bit:

                nix run nixpkgs#simplescreenrecorder
                
                1. 1

                  Nice! Will definitely try it. Feels a bit akin to comma

              2. 2

                I would be interested to see this applied to v86 and the build pipeline to compile lwIP & tailscale to wasm.

                1. 1

                  I ended up doing a similar thing but over s3 and s3fs.

                  The only practical use case I tried using this is for “overflow swap” to delay oom killings.

                  1. 13

                    Just finished “Designing Data-Intensive Applications”, was very interesting and easy to read. I’m still in the process of deciding the next one.

                    1. 6

                      I rate Designing Data-Intensive Applications very highly indeed. Might put it on the list for a re-read!

                      A friend also recommended Seven Databases in Seven Weeks but I’ve not got around to it yet.

                      1. 2

                        I will take a look, from the description it takes a very practical approach which could be a challenge, because the book was released in 2012.

                      2. 4

                        Ooo “Designing Data-Intensive Applications” is so good! I read it last year, and should probably review my notes 😅

                        1. 4

                          Nice, I am currently reading that book too.

                          As a suggestion, Seven concurrency model in seven week is also a rather nice read, and would complement nicely what you are reading now.

                          1. 2

                            Thanks for the suggestion, I will look into it.

                          2. 3

                            Truly an an amazing book.

                            Another O’Reilly with similar ideas is “Fundamentals of data engineering”. Also worth a read

                            1. 2

                              Did you read this book cover to cover? It’s so hard for me to stay focused on such a long book, but every time I pick a chapter, I learn something new

                            2. 1

                              Working on a blog post to clearly communicate the primitive root theorem. It’s a pretty slippery non intuitive proof, but very satisfying

                                And here I am, a fool with three screens, who regularly forgets which wallpaper is currently on use on that specific machine because the windows are always covering it.

                                Especially weird when I think about all the hours I spent customizing my OS/WM and actually making my own wallpapers in the early 00s.

                                1. 2

                                  ^ definitely with you there. Launching apps full screen on startup made me forget I even had a background.
