Free domain lookup software for linux

OpenDomains is a Web application that will help you provide a domain redirection service. It is easy to install and use. It allows other people to register for subdomains in your own domain.

The subdomain will then redirect visitors to a site of the users choice. OpenDomains features URL cloaking, path forwarding, meta tag support, and detailed statistics.

Chaotic Domain project is a combination of all strategy games with a new look on steroids.
Chaotic Domain aims to revolutionize the RTS industry. Made up a team of "elite gamers" (not to mention great programmers and 3D modelers) were combining the greatest features we like in other strategy games, fixes for some of the "annoying" parts of those games, and many new ideas of our own.
With a full 3D galaxy that allows you to micro- or macro-manage and very customizable games, it should appeal to every user.
Enhancements:
- Galaxy client
- Galaxy server
- Brand new network protocol with custom-built serialization
- Generator for network protocol
- 3d engine
- Stone age tech tree
- Beginnings of the "simple client"

dirqmail is a qmail patch which adds simple and fast virtual users support based on directories.
dirqmail puts users in /var/qmail/mail/< domain >/< login > directories, so for instance if /var/qmail/mail/example.org/example directory exists, qmail will treat example.org as a local domain, will accept mail for it via SMTP and QMTP daemons and will deliver mail to example@example.org as alias user using /var/qmail/mail/example.org/example as the home directory.
Main features:
- simple - you can just "see" and administer your domains and users from the command line or any file manager
- fast - checking for user of domain existence is just stating the correct directory
- atomic - all changes do not need any restarts/etc - everything just work in the "real-time"
- simple and fast aliases - just use symbolic links!
- works out of the box - just create /var/qmail/mail/domain.org/user to create user@domain.org user - permissions, ownership and Maildir creation will be handled automatically
- does not remove any of qmail features - dirqmail can coexist with any existent qmail installation - for example you can have some domains and users handled by system users (using /etc/passwd), some by qmail-users (/var/qmail/users), some by vpopmail and some by dirqmail (/var/qmail/mail)
- includes patch for checkpassword with support for POP3 (PASS and APOP) and SMTP (LOGIN, PLAIN, CRAM-MD5) - both for Krzysztof Dabrowskis and Erwin Hoffmanns SMTP AUTH patches

Geo::Lookup::ByTime is a Perl module to lookup location by time.

SYNOPSIS

use Geo::Lookup::ByTime;

$lookup = Geo::Lookup::ByTime->new( @points );
my $pt = $lookup->nearest( $tm );

Given a set of timestamped locations guess the location at a particular time. This is a useful operation for, e.g., adding location information to pictures based on their timestamp and a GPS trace that covers the same time period.

INTERFACE

new( [ points ] )

Create a new object optionally supplying a list of points. The points may be supplied as an array or as a reference to an array. Each point may be a reference to a hash containing at least the keys lat, lon and time or a reference to an object that supports accessor methods called latitude, longitude and time.

If a coderef is supplied it is assumed to be an iterator that may be called repeatedly to yield a set of points.

add_points( [ points ] )

Add points. The specification for what constitutes a point is the same as for new.

nearest( $time [ , $max_dist ] )

Return a hash indicating the estimated position at the specified time. The returned hash has lat, lon and time keys like this:

my $best = {
lat => 54.29344,
lon => -2.02393,
time => $time
};

Returns undef if the position cant be computed. By default a position will be calculated for any point that lies within the range of time covered by the reference points. Optionally $max_dist may be specified in which case undef will be returned if the closest real point is more than that many metres away from the computed point.
If the requested time coincides exactly with the timestamp of one of the points the returned point will be at the same location as the matching point. If the time falls between the timestamps of two points the returned point will be linearly interpolated from those two points.

In an array context returns a list containing the synthetic point at the specified time (i.e. the value that would be returned in scalar context), the closest real point and the distance between the two in metres

my ($best, $nearest, $dist) = $lookup->nearest( $tm );

get_points()

Return a reference to an array containing all the points in ascending time order.

time_range()

Return as a two element list the time range from earliest to latest of the points in the index. Returns undef if the index is empty.

hav_distance($pt, ...)

Exportable function. Computes the Haversine distance in metres along the line described by the points passed in. Points must be references to hashes with keys lat and lon.
