  • Re: Perma redirect (301) for SOL website pages
    Board » Technical Discussion
    Hi,

    Those INFO links are done (currently) manually by ops. It might get better (automatic) in the future but currently it is what it is.

    The http -> https transition that was done only impacts local URLs, not other domains.

    Hi all,

    I've enabled today the HTTP perma redirect (301) for http:// -> https:// . Please let us know if you encounter problems.

  • Re: Optimal Angles Solution
    Board » Technical Support
    Hi George,

    Unfortunately Bimmer is no longer with us.

    In the html client, the coordinate formatting can be changed to not include the degree sign through settings.

    You might also want to check if client's built-in max calculator in "tools" (misc tab) is what you need. If you feel the calculator is lacking something from "optimal angles" features that would be useful for you, please let me know so I can see what I can do for the built-in tools.

    The direct copy to clipboard is not something browsers want to freely allow due to security reasons, thus there is the POI step in between.

  • Re: Colour of boat track and size of the time marker
    Board » Technical Support
    While I don't fully follow what you refer with what, the predictor color could be changed through settings. In my own terminology "track" would refer past track and "predictor" refers to predicted future positions.

    The problem kind of sounds like you had something to occur for your DC-aware predictor. If it is enabled, COG & TWA predictors are dull colored and only the DC-aware predictor should be the bright one. The DC-aware predictor can visually seem "disappear" e.g. when you add TWA=0 DC (because the boat remains stationary from that point on). It's kind of counterintuitive. ...I can imagine this condition occuring e.g. when nearing PR's finish line. Is it relevant to your case?

    A bug in the predictor calculation is of course also possible but without screenshot or some other evidence it's a bit hard to fathom the cause.

    Another unintuitive DC-aware predictor trap occurs when one has DCs in future and BBQes. The bright track will keep showing the course after the next DC so there might be no visual change in the bright predictor that would alert to the problem.

  • Subdomain usage/usecases
    Board » General Discussion
    Hi all.

    Is anyone using the "subdomain" feature such as race1.sailonline.org in different browser tabs/windows? Could you please tell me what's your usecase if you're using them?

    I might need to put some restrictions on them in the near future but I'd like to preserve useful use-cases with a set of non-wildcard subdomains, if they're being used by some.

    Thanks in advance.

  • Re: Suggestions to extended predictor

    Hi,

    I've wanted to have the very same feature myself so it should eventually appear. In addition to many others such as aiming from predictor, estimating manouver performance effect, etc.

  • Re: Legality of the use of extra zoom on the apparent size of end points of finish line
    Board » Sailonline Race Committee » Rules and Decisions
    All marks and finish line endpoints are singular coordinates on server side. That is, the server thinks their diameter is zero.

    However, I don't believe those "closest" pixels are really necessary in practice anyway as we talk very very small distances per pixel. I'd recommend leaving at least 0.002 degree margin in angle to be on the safe side (it's easy to check that the COG number in the infobox changes when aiming).

    The finish line endpoints are not provided by the server currently but they are calculated by the client(s), which is a potential (small) error source on their position. There was an unfortunate incident not so long ago related to it because html5 client finish line code pre-dated my access to server-side formulas. I'd like to change this among many other things eventually such that the finish line coordinates are provided by the server so such errors would no longer be possible.

    Occasionally pixel rounding related "jitter" may result in different positioning for the very same line so "crossing" is not even well-defined if only considered what is seen visually for a line.

  • Re: Public testing new HTML5 client
    Board » General Discussion
    Hi all,

    I've just updated the dev version with lots of changes. It is possible to enable DC-aware predictor already, however, there are a few caveats. The DC-aware predictor does not consider performance losses at turns correctly. Initial performance is consider correctly like previously, however, when firing any DC, the performance gets beamed up to 100% and remains there for the remaining predictor length. In addition, the calculation only runs with 30s accuracy wrt. boat movement.

    There is now BBQ warning sound and a few new ruler related buttons that were requested.

    Some changes are (should be) user invisible library updates but they might introduce new problems (or bring back vanishing fleet problem which has caused me to hold back one particular library update).

  • Client Buttons Changed
    Board » General Discussion
    Hi all,

    I've now altered the "GO TO RACE" button so that it leads to HTML5 client (and race registration link likewise leads to HTML5 client).

    If you still want to access the old flash client, a smaller button above it that used to point to HTML5 client is left for your convinience. However, with the demise of Flash support in Web browsers imminent, I'd strongly recommend contacting me if you have strong reasons why you cannot use HTML5 client but need to keep using Flash client so I can see if I can somehow help the situation.

    Happy SOLing.

Sailonline’s 15th Birthday Balloon Race
Sailonline offers a huge variety of boats to sail in. One of the more unusual ones has got to be SOL's Balloon, which was polarized by past SOLmaster 76Trombones. Notably, the SOL Balloon will actually ‘sail’ in other directions other than straight downwind, although it will not 'sail' over land or beyond a 'beam reach'. Like in 2013 and 2018, we will be taking the Balloon across the Atlantic from St. John's and 'land' it in the sea off the Cliffs of Moher.
