Free colorado lottery software for linux

PHPlottery project is a script for running a simple lottery without requiring users to register. This is simply done by creating a key-pair.

This pair is then known by the user and by the application for later use. To prevent simple abuse, the script can use IP-store/block and cookies. When the lottery should decide the winner, a key-pair will selected out of the database.

The public key of this pair will be sent out to everybody who is supposed to know the result of the lottery. Winners have to submit the correct private key to prove their identity.

WBXML Library project is a C library for handling WBXML (Wireless Binary XML) documents. It consists of a WBXML parser (with a SAX-like interface), and a generic WBXML encoder. The following languages are supported: WML 1.0, 1.1, 1.2, 1.3 / WTA 1.0 / WTA-WML 1.2 / CHANNEL 1.1, 1.2 / SI 1.0 / SL 1.0 / CO 1.0 / PROV 1.0 / EMN 1.0 / DRMREL 1.0 / Ericsson-Nokia OTA Settings v7.0 / SYNCML 1.0, 1.1 / Wireless Village CSP 1.1, 1.2.
Enhancements:
- Support for SyncML 1.2 and AirSync was added.
- OpenSync and Debian maintainer fixes were applied.
- An XCode project file was included. Windows and Symbian project files are currently not up to date at all.
- The license was changed back to the LGPL.

GIS::Distance::Vincenty Perl module contains Thaddeus Vincenty distance calculations.

SYNOPSIS

my $calc = GIS::Distance::Vincenty->new();
my $distance = $calc->distance( $lon1, $lat1 => $lon2, $lat2 );

For the benefit of the terminally obsessive (as well as the genuinely needy), Thaddeus Vincenty devised formulae for calculating geodesic distances between a pair of latitude/longitude points on the earths surface, using an accurate ellipsoidal model of the earth.

Vincentys formula is accurate to within 0.5mm, or 0.000015", on the ellipsoid being used. Calculations based on a spherical model, such as the (much simpler) Haversine, are accurate to around 0.3% (which is still good enough for most purposes, of course).

Note: the accuracy quoted by Vincenty applies to the theoretical ellipsoid being used, which will differ (to varying degree) from the real earth geoid. If you happen to be located in Colorado, 2km above msl, distances will be 0.03% greater. In the UK, if you measure the distance from Lands End to John O Groats using WGS-84, it will be 28m - 0.003% - greater than using the Airy ellipsoid, which provides a better fit for the UK.

NOTE: This formula is still considered alpha quality in GIS::Distance. It has not been tested enough to be used in production.

FORMULA

a, b = major & minor semiaxes of the ellipsoid
f = flattening (a-b)/a
L = lon2 - lon1
u1 = atan((1-f) * tan(lat1))
u2 = atan((1-f) * tan(lat2))
sin_u1 = sin(u1)
cos_u1 = cos(u1)
sin_u2 = sin(u2)
cos_u2 = cos(u2)
lambda = L
lambda_pi = 2PI
while abs(lambda-lambda_pi) > 1e-12
sin_lambda = sin(lambda)
cos_lambda = cos(lambda)
sin_sigma = sqrt((cos_u2 * sin_lambda) * (cos_u2*sin_lambda) +
(cos_u1*sin_u2-sin_u1*cos_u2*cos_lambda) * (cos_u1*sin_u2-sin_u1*cos_u2*cos_lambda))
cos_sigma = sin_u1*sin_u2 + cos_u1*cos_u2*cos_lambda
sigma = atan2(sin_sigma, cos_sigma)
alpha = asin(cos_u1 * cos_u2 * sin_lambda / sin_sigma)
cos_sq_alpha = cos(alpha) * cos(alpha)
cos2sigma_m = cos_sigma - 2*sin_u1*sin_u2/cos_sq_alpha
cc = f/16*cos_sq_alpha*(4+f*(4-3*cos_sq_alpha))
lambda_pi = lambda
lambda = L + (1-cc) * f * sin(alpha) *
(sigma + cc*sin_sigma*(cos2sigma_m+cc*cos_sigma*(-1+2*cos2sigma_m*cos2sigma_m)))
}
usq = cos_sq_alpha*(a*a-b*b)/(b*b);
aa = 1 + usq/16384*(4096+usq*(-768+usq*(320-175*usq)))
bb = usq/1024 * (256+usq*(-128+usq*(74-47*usq)))
delta_sigma = bb*sin_sigma*(cos2sigma_m+bb/4*(cos_sigma*(-1+2*cos2sigma_m*cos2sigma_m)-
bb/6*cos2sigma_m*(-3+4*sin_sigma*sin_sigma)*(-3+4*cos2sigma_m*cos2sigma_m)))
c = b*aa*(sigma-delta_sigma)

WWW::Yahoo::DrivingDirections is a Perl module to generate driving directions for multiple-stop trips in the United States, courtesy of maps.yahoo.com.

ABSTRACT

Object-oriented interface to the maps.yahoo.com driving directions.

SYNOPSIS

use WWW::Yahoo::DrivingDirections;
my $yd = WWW::Yahoo::DrivingDirections->new ();
$yd->add_stops ( @ARGV );
$yd->get_maps();
or
use WWW::Yahoo::DrivingDirections;
my $yd = WWW::Yahoo::DrivingDirections->new (
{
roundtrip => 1,
return_html => 1,
save_html => 0,
save_format => output_%d.html,
},
atlanta, ga,
123 fake st, boston, ma,
0 church st, cambridge, ma,
LAX,
);
$yd->add_stops ( paris, tx, 1 main st, springfield, IL );
$yd->roundtrip ( 1 );
$html_array_ref = $yd->get_maps();

WWW::Yahoo::DrivingDirections provides a simple means of generating driving directions for trips with more stops than a start and a finish. Driving from LAX airport to 1 Main St, Portland, OR to Denver, CO? Just do this:

use WWW::Yahoo::DrivingDirections;
my $yd = WWW::Yahoo::DrivingDirections->new (
LAX, 1 Main St, Portland, OR, Denver, CO
);
$yd->get_maps();

and the directions will be saved in trip_leg_1.html and trip_leg_2.html.
