gospy-applet is a GNOME 2 applet to monitor changes on remote servers. You can add a illimited number of sources to monitor.

gospy-applet is possible to detect changes in HTTP header fields, IP associated with domain name, page content, page status, page load time and so on.

Ogg::Vorbis::Header is an object-oriented interface to Ogg Vorbis information and comment fields.

SYNOPSIS

use Ogg::Vorbis::Header;
my $ogg = Ogg::Vorbis::Header->new("song.ogg");
while (my ($k, $v) = each %{$ogg->info}) {
print "$k: $vn";
}
foreach my $com ($ogg->comment_tags) {
print "$com: $_n" foreach $ogg->comment($com);
}
$ogg->add_comments("good", "no", "ok", "yes");
$ogg->delete_comment("ok");
$ogg->write_vorbis;

This module presents an object-oriented interface to Ogg Vorbis files which allows user to view Vorbis info and comments and to modify or add comments.

CONSTRUCTORS

new ($filename)

Partially opens an Ogg Vorbis file to ensure it exists and is actually a Vorbis stream. It then closes the filehandle. It does not fill in the objects data fields. These fields will be automatically filled the first time they are accessed using the objects instance methods. Returns undef if there is a problem opening the file or the file is not valid Ogg Vorbis.

load ([$filename])

Opens an Ogg Vorbis file, reads its information, and then closes the filehandle. Returns undef if there is a problem opening the file or the file is not valid Ogg Vorbis. This is both a constructor and an instance method. The filename is required in constructor context, but should be left out when you call this as an instance method on an object. When called as an instance method, it (re)loads the info and comment data from the file. This can be used to reset the state of the object if write_vorbis hasnt been called. Note that the path parameter is ignored in instance context.

INSTANCE METHODS

These methods may be called on actual Header objects, using the -> operator or indirect objects as you prefer.

info ([$key])

Returns a reference to a hash containing format information about the Vorbis file. Hash fields are: version, channels, rate, bitrate_upper, bitrate_nominal, bitrate_lower, and bitrate_window, length. The bitrate_window value is currently unused by the vorbis codec. You can modify the referenced hash if you want, but I wouldnt suggest it.

The optional key parameter allows you to extract a single value from the internal hash (passed by value, not reference). If the key is invalid, undef is returned.

comment_tags ()

Returns an array holding the key values of each comment field. You can then use these values to access specific fields using comment. This may seem somewhat clunky at first but it will speed up most programs. In addition, it makes it easier to support the Ogg Vorbis comment standard which allows multiple fields with the same key.

comment ($key)

Returns a list of comments given a key. If the key does not exist, returns undef.

add_comments ($key, $value, [$key, $value, ...])

Adds comments with the given keys and values. Takes an array of alternating keys and values as parameters. Keys and values should be valid ascii in the range 0x20 - 0x7D and the key should exclude 0x3D (=). This is a subset of the Vorbis standard which allows this range for the key field and all of utf8 for the value field. This will be fixed in future a release.

If an odd-length array is passed in the routine will fail and return undef. Key and value will be trimmed of characters which do not match the format requirement.

edit_comment ($key, $value, [$num])

Edits a given comment field. The optional num field is used to differentiate between two comments with the same key. If no num is supplied, the first value--as reported by comment--is modified. If the key or num are invalid, nothing is done and undef is returned. If all goes well, the old value is returned.

delete_comment ($key, [$num])

Deletes the comment given by key. The optional num value can be used to specify which comment to delete, given duplicate keys. Leaving num out will result in only the first instance being deleted. Returns undef if key or num are invalid. If all goes well, the value of the deleted comment is returned.

clear_comments ([@keys])

Deletes all of the comments which match keys in the input array or all of the comments in the stream if called with no arguments. Returns undef if any key is invalid, although all keys in the input array up until that key will be cleared. Returns true otherwise.

write_vorbis ()

Write object to its backing file. No comment modifications will be seen in the file until this operation is performed.

path ()

Returns the path/filename of the file the object represents.

Audio::TagLib::MPEG::Header is an implementation of MP3 frame headers.

SYNOPSIS

use Audio::TagLib::MPEG::Header;

my $i = Audio::TagLib::MPEG::Header->new($data);

This is an implementation of MPEG Layer III headers. The API follows more or less the binary format of these headers. Refer to

http://www.mp3-tech.org/programmer/frame_header.html

new(ByteVector $data)

Parses an MPEG header based on $data.

new(Header $h)

Does a shallow copy of $h.

DESTROY()

Destroys this Header instance.

BOOL isValid()

Returns true if the frame is at least an appropriate size and has legal values.
%_Version

The MPEG Version. keys %Audio::TagLib::MPEG::Header::_Version lists all available values used in Perl code.

PV version()

Returns the MPEG Version of the header.

IV layer()

Returns the layer version. This will be between the values 1-3.

BOOL protectionEnabled()

Returns true if the MPEG protection bit is enabled.

IV bitrate()

Returns the bitrate encoded in the header.

IV sampleRate()

Returns the sample rate in Hz.

BOOL isPadded()

Returns true if the frame is padded.

%_ChannelMode

There are a few combinations or one or two channel audio that are possible. keys %Audio::TagLib::MPEG::Header::_ChannelMode lists all available values used in Perl code.

PV channelMode()

Returns the channel mode for this frame.

BOOL isCopyrighted()

Returns true if the copyrighted bit is set.

BOOL isOriginal()

Returns true if the "original" bit is set.

IV frameLength()

Returns the frame length.

copy(Header $h)

Makes a shallow copy of the header.

mod_sesehe SEcure SErver HEader is an Apache module that disguise or remove "Server: " HTTP header.

The ServerTokens directive currently can at best be set to Prod, which will cause apache to return "Apache" as Server header. Some problem still occurs:
First, the level of security by obscurity of this directive is not acceptable by some people that just want to change it to some other value, without re-compiling Apache, or people that even want to simply drop the "Server: " header. Secondly, if apache is configured as a reverse proxy, and a malformed request is received, then it will display its own server token instead of the backend one, so we need to handle error response header.

I developed this tiny module by hijacking normal behavior of (reverse) proxy feature of Apache : i.e. even if a request is not a proxy request, I tag it as if it was, to make Apache core let me do what I want with this header.

BBCNews.co.uk RSS reader is a SuperKaramba theme.

Based on LTRSS reader (http://www.kde-look.org/content/show.php?content=27639) I really didnt do almost anything to the original script, just changed things to BBC and made the header pic.

I just thought that since i did it i might as well post it here.

libpal allows you to create your own forged IP, TCP, and ICMP packets. libpal project is straightforward to use and is a powerful tool for building artificial TCP/IP packets.
At the time of this writing the only supported platform is LiNUX/i386, but things will develop, so give us some time and check back or - even better.
Main features:
- ethernet header, type and payload (CVS only)
- (R)ARP packets (CVS only)
- IP header, options and payload
- ICMP messages
- TCP header, options and payload
- UDP header and payload

XML::Mini::Element::Header Perl module is used internally to represent < ? xml blah="hohoho" ? > type headers.

You shouldnt need to use it directly, see XML::Mini::Elements header() method.
