What happened to http://data.oreilly.com/knots
« on: March 05, 2013, 03:50:48 PM »
Hello All,
Does anyone know what happened to http://data.oreilly.com/knots? I used this site to return the sting run algorithm and left/right side expansions for casa/sobre coded knots. If I remember well, the page was maintained by Tim Allwine (owner? of data.oreilly.com/jallwine/knots); the latter page offers more coding options (OOUU, OUUO, et al.) of course, but doesn't provide the left/right expansion dimensions.

Please reply if you know what has happened to this resource, or if you know of a similar resource that I might use instead.

Regards and Happy Knotting,
J.S.Sandler

Hi J.S.

I have this link to Mr Allwine's Turks head online program. http://data.oreilly.com/jallwine/knots/

I verified that it is working.
Hope this helps you.

I am able to reach that site without problems. Thanks.  ;)  It's the other site I'm looking for. http://data.oreilly.com/knots. It was helpful in showing the next expansions from a base TH.

Thank you and Happy Tying,
J.S.Sandler

We moved the server and didn't get all the code moved to the new server. Also this was a research project that I started many years ago and wasn't really meant for public consumption. That said I found I like this type of format much better. I know longer need pins or tubes to tie any of the knots that are doable in hand this type of out put gets my head right when tying a particular knot. For those who never say this output here is a 12 x 5 knot.


12 x 5
p = 12, b = 5, n = 2, r = 2, v = 3, m = 1, delta = 2
when (m*b)+1 % v -> 0
  then
      (m*b)+1 / v = delta
 

right side expansion: 26 x 11
left side expansion: 22 x 9
History:

    Start with:
    2 x 1 with a left side expansion.
    12 x 5

CBN:   0   2   4   1   3

       2   4   1   3   0   2   4   1   3   0   2
       U   O   U   O   U   O   U   O   U   O   U
       O   U   O   U   O   U   O   U   O   U   O
       2   0   3   1   4   2   0   3   1   4   2


    [ 1]( ) --> pin 1 Free run to pin 2
    [ 2](0) <-- pin 2 O,U pin 3
    [ 3](0) --> pin 3 U,O pin 4
    [ 4](1) <-- pin 4 O2,U2 pin 5
    [ 5](1) --> pin 5 U2,O2 pin 1
    [ 6](2) <-- pin 1 O3,U3,O pin 2
    [ 7](2) --> pin 2 U3,O3,U pin 3
    [ 8](3) <-- pin 3 O2,U,O,U2,O,U,O pin 4
    [ 9](3) --> pin 4 U2,O,U,O2,U,O,U pin 5
    [10](4) <-- pin 5 O,U,O,U,O,U,O,U,O,U,O pin 1
 Overs: 28
Unders: 27


When I get the site up or moved etc I'll let everyone know.
