Re: Public testing new HTML5 client

Board » General Discussion

What you describe is caused by the different update times of the fleet, and your own boat. The fleet (all boats) are updated once a minute, so they make jumps of 1 minute. Your own pink boat is updated more frequently, and will jump ahead before the fleet catches up.

Your boat is also part of the fleet, so an version of your boat is updated together with the rest of the fleet once every minute. It looks like it is sailing behind your pink boat. In the Flash client this boat is made invisible, buy you can make it visible by clicking your own name in the leaderboard-tab.

Personally I always liked to see my shadow, so I could better compare how I was doing relative to the fleet. But it may be confusing to have it always visible, especially to new SOLers.

I think you problem would be solved with the following feature:
Make drawing of own boat in fleet invisible unless own boat is selected in the ranking-tab.
Even better may be to have three options in the settings: {always show, never show, only when selected}, with as default one of the last two.

A new version of the client has been published. You can simply refresh/reload browser tab.

If this new version doesn't work for you, let us know. You can use the older version by appending
```
?version=old
```
to the url, or (for the current two races) by clicking the links below.
Dondra to Sanya 2020
BA-Rio 2020

What has been changed? Here is a list of the most important changes (credit to ij):
- Tack/Gybe button label split to either “Tack” or “Gybe”
- POIs show local wind info
- When WX panel is focused, left and right arrow keys step time backwards and forwards
- Minor tweaking to mouse handling code to prepare for touch interface improvements for ruler and steer tools (should not change anything but may still break something)
- Highlight race leader setting
- Attempt to prevent browser’s autocompletion for text input fields
- Chat input text area style changes (one additional line and scrollbar enabled when necessary)
- Boat scale setting
- Boat list save/restore
- UI changes to enable Touch UI
- WX panel styling improvements (roughly constant width)
- Control panel layout tweaks, ranking tab in particular (to solve iPad UI issues)
- Chat odd/even bg color tweak to hopefully avoid some “bg jumps” when new messages appear
- Fix stale boat filter when a boat list that was in “show only” state is deleted
- TWS contours. There are still some horizontal gap artifacts in contours and when wx area appears more than once, only one of them draws contours currently; in practice, neither limits significantly the usefulness of contours. Contour density is configurable through Settings.
- Quick-access buttons for show TWS/TWD (beside the wind arrow/barb)
- Ranking tab click vs mouseup problem (reported to occur with Edge)

PS: for early access to updates like this, you can append
```
?version=dev
```
to the URL. This "dev"-version gets updated more frequently (and without notice). Drawback is that there may be more bugs. At this moment the "dev"-version is not ahead any updates.

I don't think double (or triple) clicking has been implemented to go to max zoom immediately. But something very useful you may not be aware of is that you can shift-click and drag. This selects a region on the map, and when you release the mouse button, it zooms to that region of the map. Does that work for you, or would you still really like a way to go to max zoom immediately?

In general, there multiple differences with the Flash client. Some things work slightly different, other things are simply not copied from the old client. If you find some feature in the Flash client useful, let us know what you use it for (like Rod did). This really helps. Maybe there is an alternative to achieve the same (or better), and if not. Who knows ij wants to implement it (for this it really helps to know how people are using features, and why they want them).

Re: Public testing new HTML5 client

I have just noticed: if you have not yet registered in the race, to button to go to the new HTML client does not work properly, it will send you to the registration page, which will have forgotten that you wanted to see the new client and send you to the old Flash client. After registration, you can close the page/go back, and click the "New HTML5 client" button again.

I will try and think of a fix for this.

Public testing new HTML5 client

Board » General Discussion

Blog post "New HTML5 client"

Today a button appeared above the usual "GO TO RACE" button. This new button reads "New HTML5 client" and clicking it brings you to the new HTML5 client. You may have heard the rumours that this new client was under development and will eventually replace the Flash client we are used to. As Flash is being phased out it is becoming increasingly difficult to use sailonline in new browsers, so it is vital to have an alternative. Let me take this opportunity to thank our SOLer ij, who has been responsible for the existence of this new client, brightening the future of sailonline.

We are now making this new HTML5 client available for everyone to use. Be aware that the client is still in a testing phase and that there may still be some bugs and problems with it. The user interface and general functionality are mostly the same as in the Flash client, but you may notice some differences, for example:
- There are no contour lines indicating wind strength. The client is not completely finished yet and this is one aspect where work is still being done.
- The TWA input field for steering requires a + or - sign. This should prevent some of the accidental tacks we have probably all experienced when we forgot the - sign.
- You can monitor multiple chatrooms at the same time. You can now use the chatrooms English and the one for your native language at the same time!
A longer list of changes can be found here. Use that chat and forum to talk with each other about using the new client and its new features. Some SOLers already have some experience with it and may be able to give you some tips and tricks.

WANTED: Testers new client

Board » General Discussion

Hello all,

First let me bring you the good news that a SOLer has stepped up a while ago and started work on a new HTML5 client. We hope this client will ultimately replace the current Flash client, as Flash support gets removed from browsers over the next years.

This new HTML5 client is now ready for some testing. We would like to select a handful of people that want to (1) test the new client and (2) be a guide to the new client once everyone else starts using it.

As someone in this group
(1) you will communicate with each other about their findings and maintain a list of bugs and feedback together, and
(2) Once we believe the most important issues are all resolved, we will open the new client to the public and we would like you to answer questions in chat/forum when you are online and generally help people get started. If new problems are discovered, you can add them to the list.

For (1) it would be nice if some of the people in the group have some affection/knowledge of web technologies or software testing.

For (2) it would be nice if you are an active SOLer that is available in chat relatively frequently. It would be good to have some people from the non-English communities, like for example French, Italian and Spanish. But communication within the group and with us will be in English. Also SOLers from the Americas and Australasia are most welcome to join in order to have our "guides" spread over all time zones.

If you are interested to be part of this group of "early adopters", please send an e-mail to my @sailonline.org address: huib@
And if you know of people that may be interested, but sure to point them to this post.

Re: qtVlm thread

Regarding the converter on sol.kroppyer.nl:
1) I have updated the autodetection for columns. It should now automatically detect the COG (T) column instead of defaulting to the 8th column.

2) The default is still to use AWA for the sign of TWA. The recent example csv file I have shows negative AWA values where TWA values are positive, leading me to believe that the TWA values still do not distinguish between port and starboard tack while AWA values do.

Re: API

Board » Technical Discussion

There is an API, but it is not publicly documented (actually, it is not documented at all). Many people (including myself) have used this to create third party tools. There is an android client that uses this API. I believe only the process of registering in a race was a problem, otherwise a complete client can be built.

Significant work has been done with relation to a non-flash client (HTLM5). If you are interested in working on such a client (as sol volunteer or as a private project) then please do get in touch (via the admin@ e-mail address, or contact me directly via huib@). We would love to get you started. Also for other 3rd party tools I offer my help in working with the API. I always do this with one condition: the tool should be publicly available to everyone for free. I have helped Kipper for example when he was getting started with his DC checker and/or auto grib downloader tool(s).

Re: Help with polars ( with help of brainaid toolbox)

Board » Technical Discussion

I started developing SPINNACER exactly with this in mind: I needed a way to accurately determine SOG at a given windspeed and angle and use this in calculations.

SPINNACER offers both a graphical as a numerical way to do this. It may be a bit cumbersome at the start, but it sounds like this is the tool you're looking for.
