   Interesting – seems like there's a bit of overlap with Project Gitenberg ( https://www.gitenberg.org/ ).

   I find it particularly interesting that this post steals images from my blog [1], then adjusts the saturation / brightness on them so that a reverse image search thinks they are unique. Please don't do this. Folks put effort into

    I have the same meta-question, and would love to hear what other folks think – I enjoy Exponent a lot, but feel like it veers into just-so stories [1], and the theories / models could be interpreted to argue for any particular outcome

    Another example of Reed-Solomon codes in the wild: RS codes are used in QR codes because they're particularly resistant to localized errors, e.g. a physically-contiguous section of the code becoming damaged or unreadable.

    I'm using Guile for Ao, a Scheme-based tool for solid modeling: https://mattkeeter.com/projects/ao (previous on HN at https://news.ycombinator.com/item?id=12319406 ) It's been a generally good

    Folks are building it on Linux already, generally with success (and failure to build on Linux is considered a bug, so raise a Github issue if that happens). Windows is less likely, as Guile (an FSF project) doesn't have an officially s

    Glad to hear that you're enjoying Antimony! I'm planning to keep either Antimony or something similar alive into the future. Antimony is approaching convergence, so development has slowed down – not sure whether major new feature

    I got Ao to a working state a few months before that exchange on the guile-users mailing list. Guile works fine for Ao – it's clean and simple, plays nice with C FFI, and has a good REPL. Racket was lower-impedance for the project disc

    I'm currently writing a toy library to play with hierarchical graphs – if Ao is a minimal implementation of Antimony's CAD, this will be a minimal implementation of the graph engine. Beyond that, it's a small matter of progra

    The redefined + only behaves differently when one or more of its arguments is a token object, so normal math works fine. Generic procedures may be a cleaner way to do this, but I only discovered GOOPS after this implementation was already w

    I assume you're talking about Antimony. Its graph UI is done in Qt, using the QGraphicsView framework. That section of the code is at https://github.com/mkeeter/antimony/tree/develop/app/canva
