  • Guide: Get OpenLDAP to work on arm64 - modifying bitnami/openldap image.
    3 projects | | 27 Sep 2022
    Hello there, In my search for a good self-hosted wiki/documentation app, I found Outline, it's so beautiful, but I found that I needed to run an LDAP server for users (Outline supports file-based backend as well). I struggled to find a good LDAP docker image for arm64, so I decided to modify Bitnami's image to include an arm64 version of OpenLDAP.. which I didn't find so I had to compile it from source. I hope you find it helpful

  • Library for Tree-like data structure
    2 projects | | 3 Oct 2022
    I am about to start a new project in Haskell, model checking with (new) tree-like data structures. I think it is best to start building on a library such that i can already have elegant base functions, yet i am wondering what library is currently the standard? I read about fgl ( ), yet it is a very old library.

    Using fgl but only as a data structure this time, with edge labels denoting whether the target is a big room. Not using any of its algorithms as it doesn't have anything built-in for "traversal with re-visiting".

    For part 2, instead of trying to union-merge from the lowest points, I simply found all connected regions of <9. I say "simply" because I just threw things at fgl, but setting the graph up first took a bit of work. buildGr is fast but picky about the exact order things come in with.

What are some alternatives?
