HydraVM: Low-Cost, Transparent High Availability for Virtual Machines - Hou, Kai-Yuan; Uysal, Mustafa; Merchant, Arif; Shin, Kang G.; Singhal, Sharad
Keyword(s): Virtualization, High Availability, VM Checkpointing, VM Restore, Shared Storage
Abstract: Existing approaches to providing high availability (HA) for virtualized environments require a backup VM for every primary running VM. These approaches are expensive in memory because the backup VM requires the same amount of memory as the primary, even though it is normally passive. In this paper, ...

wiki::toolkit::plugin::rss::reader
Wiki::Toolkit::Plugin::RSS::Reader(3pm) User Contributed Perl Documentation Wiki::Toolkit::Plugin::RSS::Reader(3pm)
NAME
Wiki::Toolkit::Plugin::RSS::Reader - retrieve RSS feeds for inclusion in Wiki::Toolkit nodes
DESCRIPTION
Use this Wiki::Toolkit plugin to retrieve an RSS feed from a given URL so that you can include it in a wiki node.
SYNOPSIS
use Wiki::Toolkit::Plugin::RSS::Reader;
my $rss = Wiki::Toolkit::Plugin::RSS::Reader->new(
url => 'http://example.com/feed.rss'
);
my @items = $rss->retrieve;
USAGE
This is a plugin for Wiki::Toolkit, a toolkit for building wikis; therefore please consult the documentation for Wiki::Toolkit for relevant
information. This module can, however, be used standalone if you wish.
METHODS
"new"
my $rss = Wiki::Toolkit::Plugin::RSS::Reader->new([options]);
Create a new RSS reader. Valid options are "url" or "file" (a path to an RSS file); only one can be specified.
"retrieve"
my @items = $rss->retrieve;
"retrieve" will return an array of hashes, one for each item in the RSS feed. The hashes contain three items, "title", "link", and
"description".
If the URL or file you specified cannot be retrieved/read, "retrieve" will return undef rather than blowing up and surprising the person
reading your wiki. If you want, you can specify "debug" to be 1 in the options to "new", which will cause the module to croak instead of
failing silently.
