   I personally also find https://hisgis.nl/ an interesting resource, especially if you want to know about the 1832 kadaster maps, which are far more detailed that the maps that topotijdreis shows of that period. I do not know

   Hi Kragen, for a long time, I have been pondenring about a high-level 'programming' languages about structured data. It is by far finished, but I am attempting to deal with the problem of different memory models from the other end

   There are some things that software engineering and philosophy have in common. One is that they are both about (abstract) concepts and their relationships. Another is that they are based on languages. Just like software engineers have the t

   I also do not understand why. When they were the first, they could have made some money by making it available to top professional players, who probably would want to pay thousands of dollars to play against it. Now, there are enough reimpl

   I wrote something similar in JavaScript. You need something like: function as_and_bs() { return parse_text("aaaaabbbaaaabb", make_grammar( parse_text("root : (\"a\" SEQ \"b\" SEQ)SEQ OPT",

   Earlier this year, I wrote a small interpreting parser in JavaScript, which takes a grammar from a string and parses some input from a string according to the grammar into an AST. It is embedded in the page https://fransfaase.git

   Not very likely that this is correct, because the problem is know to be NP-complete https://en.wikipedia.org/wiki/Hamiltonian_path_problem and this seems to imply that NP=P. And that is what the author claims in the co

    What is the most esoteric programming language under the programming languages that were not intended to be esoteric? The first language that comes to my mind is APL. Any body having a better suggestion?

    Thanks! It is not so much a parser generator as in interpreting parser. It is based on https://fransfaase.github.io/ParserWorkshop/Online_inter_par... which I developed earlier this year. My idea was not to use the inp

    This reminds me of my own attempts to read Acorn Atom programs from cassette tapes. I wrote a program to process wave files. Took me quite long to find a reliable method for recognizing the zero's and one's. But even that was not

    I recently wrote a BrainFuck program with the same functionality as hex0 in stage0. This does not solve the fundamental problem of trust, because you still need an executable BrainFuck interpreter or compiler. But there are many more differ

    I have written a BrainFuck generator for writing a BrainFuck program which could replace the hex0 seeds. See https://www.iwriteiam.nl/BFgen.html

    The performance argument is not a real issue if it is only used as a replacement for sed/xxd combination. And yes, it was designed to make programming difficult, but one could argue that it is easier to verify manually than machine cod

    I wonder if Brainfuck could be used for https://github.com/oriansj/stage0-posix ? It would not surprise me if there is no other language for which there are so many interpreters written in so many different programming

    I wonder what the purpose is of adding more and more symbols to a standard that was originally intended to represent texts in written languages. It almost feels like it is the easy part of 'improving' the standard: Adding more sym

    The distinction between a scanner and a parser is somewhat arbitrary. One could use one and the same formalism for it. The scanner usually deals with things that are considered 'atomic' elements in the language, while grammar is u

    Quite possible that they used frames before and that the notes were displayed on the side of the text. Now you have to use the back button to go back to the main text. I understand that there are a number of version of Ulysses. I wonder if

    I understand that you put pre-trained between quotes, but I find it a little far fetched, because, as far as I understand, there is no evidence that any setting of the synpasis strength of certain neurons is transfered through DNA, it is on

    I recently wrote a similar parser, maybe less fancy, for a workshop on parsing. It does display the the abstract syntax tree with d3.js and also has a build evaluator for a limited set of language constructs. https://fransfaase.g

    Very interesting exposition and comments. I think it shows one of the 'weaknesses' of TAOCP is that it does not formalize or at least make explicit the relationship between the available operations and the final functionality of t

    For example, that you can specify that a reference to a component of a compound value enforces that that component cannot be removed. Or, that you can specify (the other way around) that whenever the referenced component is removed, the com
