Free zipcode lookup software for linux

jBitcollider is an application which can be used to lookup/submit files to Bitzi.
The Bitcollider utility allows users to uniquely identify and submit files to Bitzis community metadatabase project.
The Bitcollider can be used to identify any local file and has support for extracting metadata from MP3, WAV, Vorbis, JPEG, PNG, GIF, AVI, MPEG-1, MPEG-2, and QuickTime files.
Users can quickly look up all the known information about the given file in Bitzis metadatabase.
Main features:
- Processes files larger than 2GB in size.
- Offers the graphical interface, and drag-and-drop Bitcolliding, on non-Windows systems for the first time.
- Improves reliability of submission via browser

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.

The ICMP Hostname Tools for Linux include a responder daemon, a lookup tool, and a nameswitch module to handle ICMP host name functions.

The NSS module caches all requests (including failures) and honors the TTL value sent by the responding host. It uses a configuration file called /etc/nss-icmp.conf, which controls different aspects of its operation:

* timeout – Sets the timeout in milliseconds for ICMP host name queries, by passing the -t option to idnlookup.
* nocache – Disables the cache.
* ttlnotfound – Sets the TTL for not-found cache entries is seconds. The default is 5 minutes.

Both icmpdnd and idnlookup need to run as root, due to the fact that they use ICMP. Thus, idnlookup needs be installed SUID root.

IP::Country is a tool for fast lookup of country codes from IP addresses. Finding out the country of a client using only the IP address can be difficult.

Looking up the domain name associated with that address can provide some help, but many IP address are not reverse mapped to any useful domain, and the most common domain (.com) offers no help when looking for country.

IP::Country module comes bundled with a database of countries where various IP addresses have been assigned. Although the country of assignment will probably be the country associated with a large ISP rather than the client herself, this is probably good enough for most log analysis applications, and under test has proved to be as accurate as reverse-DNS and WHOIS lookup.

Graph-includes creates a graph of dependencies between source files and/or groups of source files, with an emphasis on getting readable and usable graphs even for large projects.
Graph-includes project is meant to be an helper tool for a refactoring effort. Usability of the dependency graphs are currently improved by customizable grouping of several source files into a single node, and transitive reduction of the graph.
Enhancements:
- Ported to non-Unix platforms (tested on Windows).
- This release has finally implemented/fixed node group coloring.
- A default path for system-includes lookup has been added.
