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.

Gini project does remote method invocation by generating bytecode for remote object proxies on the fly. Primitive types, arrays of primitive types (arrays of arrays of prim. types, and so on), as well as strings, are passed by value. Reference types, as well as arrays of reference types are passed by reference in remote calls.

Exceptions are dealt with separately - and in such a way as to allow propagation of stack-traces (which Suns RMI doesnt do.) There is no object serialization - its purely remote method invocation. Garbage collection is a hack, but seems to work. Make sure youve got weak references on the platform you are using.

The Gini Lookup Service provies a registry into which any machine on the network can stuff objects. A Gini node either finds an already-running Lookup Service on the network or starts advertising itself (by using UDP broadcast) as such. You can be notified whenever a lookup service is found or lost, or when an object is added to or removed from the registry. If there are two Gini nodes advertising themselves at one point, theyll decide which one stops.

The implementation compiles to a less than 50k jar, and the bytecode library it uses is less than 90k. A good use of it is for distributed computing, actually. But if you feel like playing with embedded devices, go ahead.a

Bitcollider provides the bitcollider 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.
Enhancements:
- The kzhash identifier used by Kazaa 2.6 and up is now calculated. (As a result, MAGNET links at Bitzi can include this identifier and work with Kazaa.)
- A video format plugin now extracts and submits information such as framerate, framesize, duration,bitrate, and codec from most AVI, MPEG1/2, and QuickTime videos.
- A problem in the original construction of the TigerTree hash value has been corrected. (Only values from updated software display at theBitzi website.)
- Calculation of MD5 and CRC32 values is now optional.

RSSTail is more or less an rss reader. RSSTail monitors an rss-feed and if it detects a new entry itll emit only that new entry.
Compile & install:
make install
Usage:
rsstail -u url -i check_interval
e.g.:
rsstail -u http://www.filmhuisgouda.nl/rss/rss.php -i 300
this will check every 5 minutes if anything new was published.
Help:
rsstail -h
will show a list of what rsstail can do for you.
Enhancements:
- A switch that limits the amount of text displayed was added.
- A switch which prevents rsstail from aborting when an error occurs (such as when hostname lookup temporarily fails) was added.
- A segfault on FreeBSD was fixed.

WebCache::Digest is a Cache Digest implementation in Perl.

SYNOPSIS

use WebCache::Digest;

# fetching a digest via HTTP
$d = new WebCache::Digest;
$d->fetch("flibbertigibbet.swedish-chef.org", 3128);

# dump header fields out for info
print STDERR $d->dump_header();

# saving a digest
$d->save("flib");

# loading a digest
$e = new WebCache::Digest;
$e->load("flib");

# creating a new digests
$f = new WebCache::Digest;
$f->create; # defaults to a digest with 500 URL capacity

# registering a URL and method in the digest
$f->register("get", "http://www.kha0s.org/">;
if ($f->lookup("get", "http://www.kha0s.org/">) {
print "hit!n";
}

# access to raw header and digest contents
print "header: " . unpack("H*", $f->header) . "n";
print "digest: " . unpack("H*", $f->digest) . "n";

# access to digest header block elements
print "Current version: " . $f->current_version . "n";
print "Required version: " . $f->required_version . "n";
print "Capacity: " . $f->capacity . "n";
print "Count: " . $f->count . "n";
print "Deletion count: " . $f->del_count . "n";
print "Size in bytes: " . $f->size_in_bytes . "n";
print "Bits per entry: " . $f->bits_per_entry . "n";

Formitable is a PHP class used to ease the creation of submit-ready HTML forms from MySQL database tables.
Formitable project analyzes the fields of a given table and outputs the best input type for each (e.g. enum type becomes radio buttons or select, set type becomes checkboxes or multiselect). Data is automatically inserted into the table upon form submission.
Main features:
- Output a complete form in a few lines of code
- Validate data via regular expressions and provide custom feedback
- Support for normalized data/lookup tables
- Easily retrieve and update existing records
- Outputs attributes such as MAXLENGTH to reflect your table design
- Customize all aspects of output, integrate forms into your layout
- Full CSS styling
- Accessibility support such as labels, fieldsets, legends and more
Enhancements:
- Forms can now be printed using a template with printFromTemplate.
- Custom template delimiters can be set using setTemplateDelimiters.
- Bugs were fixed.

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.
