    Stockfish

    Stockfish

    UCI chess engine

    Stockfish is a free, powerful UCI chess engine derived from Glaurung 2.1. Stockfish is not a complete chess program and requires a UCI-compatible graphical user interface (GUI) (e.g. XBoard with PolyGlot, Scid, Cute Chess, eboard, Arena, Sigma Chess, Shredder, Chess Partner or Fritz) in order to be used comfortably. Read the documentation for your GUI of choice for information about how to use Stockfish with it.

    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

    Fair-chess

    Fair-chess

    A new -better- chess variant , *Fair-Chess* ! (also with handicaps)

    A new -(and much better) sort of Chess game , *Fair-Chess* ! Being interested in chess for two decades now, i designed a chess variant in which the intrinsic White advantage is compensated by removing the f2 and c7 pawns (calibrated by engine analysis). Also, in such a way detailed knowledge of opening theory is not important anymore (but it still looks more like normal chess than Chess960, also called 'Freestyle' nowadays.... ). ...
