  • What is the 'accumulator in HQ9+?

    - by Koning Baard XIV
    I was just reading a bit about the HQ9+ programming language ( http://esolangs.org/wiki/HQ9 , http://en.wikipedia.org/wiki/HQ9%2B and http://www.cliff.biffle.org/esoterica/hq9plus.html ), and it tells me something about a so called 'accumulator' which can be incremented, but not be accessed. Also, using the + doesn't manipulate the result: code H+H result Hello World Hello World Can anyone explain me how this works, what this does and if it even makes any sense? Thanks

    - by flavio87
    Hi there what would you use if you had to have a div box on your website that would have to be updated constantly with new HTML content from the server. simple polling is probably not very resource inefficient - imagine also having 10'000 users and the div has to update. what is the most efficient or elegant solution for such a problem? are there existing widgets which contain this "autoupdate" functionality?
