2013-10-01 15:17:29 - SPINNACER
Hi all :)

You might have read my post about posting links to executables, well my link is approved, so here's the post I was talking about:

It's been a couple of times now that I needed to know my SOG, given a TWS and TWA that were different from my current TWS and TWA (for setting DCs mainly). The polar diagram in the client was not exact enough IMO.
So I started writing a little program that could read the polar, and interpolate for me. I called it "Sol Polar Explorer". Then I added some new things (vmc stuff, and a sort of calculator). Then I found that "Sol Polar Explorer" already existed, made by Aaron.. I decided to rename my program, "Sol Polar Explorer" is Aaron's. Besides, my program was getting more than just an explorer.

I introduce to you "SPINNACER":

SOL Polar Inspector N.N. And Calculator to Enhance Racing

:)

Once I added the last big chunk of functionality I will reveal what N.N. abbreviates, until then it's just a Polar Inspector and Calculator.

The source code of Aaron's Polar Explorer is publicly available, including the "official" interpolation that SOL uses. I implemented that, so the data should match pretty well. Thanks Aaron.

---
So what does it do?
1. It can read the files that brainaid provides as "Detailed data as CSV".
2. Show the basic polar (a bit more precise than in the client), **with zooming functionality**
3. Show the polar at a given TWS, providing TWA and SOG information at mouse location. Also: draws VMC line, with best VMC angle and speed towards mouse location. **with zooming functionality**
4. *Secret* - I'm really curious if anyone can find out what it is :)
5. Calculator: Can do almost every calculation involving, TWS, TWA, COG, BRG, VMG, VMC, DST, delay, ETA, etc..
6. Special view at a polar

---
These are some features I want to add:
- Show best VMG angles and "polar hop"-locations in "Pro Polar View"
- Make "Super Pro Polar View" better (have you figured out what it is yet?)
- Make a nice drawing representing the most important numbers in the calculator (so that stupidities get noticed in time)
- Connect with SOL for live boat data
- N.N.

If you can think of any improvement or addition I'd like to hear it. If you find bugs or have trouble of some other kind, please do tell me.

Instructions:
1. Download (.zip

if you have no clue what .tar.gz is)
2. Extract to a location of your choice
3. Run the jar file, (can be done via terminal/command prompt: "java -jar SPINNACER.jar")
4. Open a polar file (three polars are included in the download)

---
Have fun!

Admittedly I have a Legacy system which is OS X 10.4.11 (Tiger) so I am posting the errors that showed when the file failed to launch.

The file can be run with java 7 (aka 1.7) and java 6 (aka 1.6)

I've changed some of the source code so that it should be compatible with java1.4, but calculator-part is a little more work to change. So have a go at this one, see if it works, and then I might make the calculator java1.4 compatible.

SPINNACER for java 1.4 [link broken, see homepage]
(I've not tested it)

If anyone else cannot run the normal version, but can run this version, please do tell me, then I know how many people are waiting for a java 1.4 compatible calculator.

---
Meanwhile, I will post some screenshots and explanations. So that people know what to expect, and decide whether it's useful to put time and effort into getting it to work (which isn't so hard on normal up-to-date computers, no offence A2R :) )


EDIT: stripped this version further down, but it works now. but its slower, and half the functionality is missing.

EDIT: version for java 1.4 available on request. Version for java 1.5 online on homepage.

I've made a guide, to help you out if you have a problem getting the thing to work, or just to let you have a look at what you are getting yourself into before putting in the time and effort of downloading. It's usually quite easy to get it to run, but I can understand some have a little more trouble, and would want to know if it's worth it.

spinnacer v1.1 beta is available.
Java 1.6/1.7 (default) tar/zip
Java 1.5 tar/zip

changes:
- polar hop locations are shown in Pro Polar View (after super pro polar view has done its calculations)
- in Pro Polar View there is now a Slider to change TWS.
- use right click+drag to zoom if you can't use a mouse wheel to scroll.
- in Pro Polar View, left click to keep twa and vmc lines on current location (click again to let them follow the mouse again)
- You will automatically be notified if there are new versions
- The polar bear is included in the download and won't be downloaded again each time you start the application, you will now be able to bear away and head up properly when you are offline.
- added two new polars

There is no updated guide yet, as it's still a beta version.

Yes, it is a fractal, or rather, they are fractals.

I found it somewhere in the messy, dusty place that is part of my hard-drive, looking for something else. I thought it looked cool, and deserved a better place. So I took the dust of, and there it is :D

Cross the Convergence 2026 - Samoa to Hawaii


The second race of our new series of ocean voyages across the World’s convergence zones, takes us northward again up the Pacific Ocean, now from Samoa at 13.5 degrees South, across the Equator to Hawaii, famed for its breaking surf and active volcanoes, on the edge of the Tropic of Cancer at 19.5 degrees North. It’s 2300nm, so we’ll take our very steady Steinlager II. Race #1982

Beketov by Balloon 2026 - In Siberia


Way-back-when France and England, and Spain as well, were squabbling about who should control what of North America, only to lose the most of it to their own insurging colonists, their eastern European neighbour empire, Russia, was quietly assimilating vast, thinly nomadically populated territory of its own – Siberia! Amongst the many explorers and adventurers that served Russia so well in these conquests was the Cossack hetman Pyotr Beketov. Let’s pretend we’re he and eschewing horseback, let’s travel by balloon from Yekaterinberg to Krasnoyarsk – just a short 2000km (1100nm) section of the Trans-Siberian Express’ 9289km!

West Papua to Oregon 2026

Our next race in our Ocean Championships is the first of a series of great natural migrations we will track in 2026. The leatherback turtle is the most widely distributed marine reptile on planet Earth, and chooses to breed in warm tropical waters, but prefers to forage in more temperate habitats, travelling thousands and thousands of miles effortlessly annually to maintain this way of life. Our race will follow one of the typical trips of this turtle, from breeding grounds in the seas off West Papua to the coast of Oregon. It’s only 5900nm, so to keep up, but in comfort, we’ll follow in our Gunboat 90.
