Just in case there are any like-minded 'nerds' out there:
I am an open-source computing fanatic, and 99% of the time I avoid Windows-based systems like the plague. Unfortunately, for me, that residual 1% pretty much means 'when running Bridge scoring programs'.
1 I (still) have a working Linux-version of Jeff Smith's programs, though I no longer use them. Strangely, it would only work with versions dated up to around October 2015 I think it was. I couldn't get more modern versions - including EBUScore - to behave, but I don't now have any incentive to do so, so that is history.
2 Not that it is any use to anyone, but I have the ancient Ruth Edmondson 'Score' program working perfectly under Linux, but that program pre-dates P2P, yet alone Bridgewebs and NGS, so it is of even less use than last week's completed Times Crossword.
3 I failed miserably with ScoreBridge.
4 The Jannersten system, which includes Jeff Smith's programs as its scoring engine, sort of worked, but the Linux version couldn't cope with their convoluted licensing algorithm. We used that system at Mountnessing for almost a year, and I freely exchanged event files, player databases, etc between my desktop Linux version and the XP laptop Windows Jannersten-embedded version.
5 I have 'dipped my toe' into getting John & Mirna's system working under Linux. Just in case anyone else out there is interested, the topic is 'on my radar' but I haven't had time to work on it for a while. It does look to me to be do-able. Basically, the idea is to run the system through WINE, which, for the uninitiated, is a kind of front end for Windows applications that (in theory) enables them to run under other operating systems, such as Linux or Apple. The recent changes that have been made to the BridgePals system appear to me to make success more, rather than less, likely, especially the issue about the port number used.
