  • ANN: Dogelog Player 1.2.3 (Time Conversion)

    From Mild Shock@21:1/5 to All on Thu Oct 3 15:29:24 2024
    Dear All,

    We are happy to announce a new edition of the Dogelog player:

    - New atom_time/4:
    The predicate sys_time_atom/3 is now officially
    called atom_time/3. The underlying strftime() and
    strptime() routines can represent more than just
    local time. We therefore introduced atom_time/4
    with an options list.

    - Improved open/4:
    The open/4 predicate and its HTTP client functionality
    was removed from library(util/spin) and moved to
    the core. In addition, open/4 can now return options
    such as the final URL via uri/1 and the received
    headers via fields/1.

    - New http_server_close/1:
    The HTTP server in library(util/spin) has undergone
    some extensions. The asynchronous processing has been
    improved, so that HTTP server set-up, HTTP client round
    trip and HTTP server tear-down can be implemented in
    the same application despite being single threaded.

    Have Fun!

    Dogelog Player is a Prolog system written 100% in
    Prolog itself. It features a library(aggregate), the
    bread and butter of statistics. Unfortunately it
    inherits some defects from its ancestors. We show
    its bad performance in a Million Rows Challenge
    and offer an alternative.

    When calling the predicate sample/2 it will give
    us values X1, .., Xn. And from this we can recompute
    the mean and the standard deviation. We could get
    rid of the horrendous memory footprint and gain
    speed, in that we used an aggregate/3 bootstrapped
    from a new library(util/hash).
