Free matter of trust software for linux

Matrix Public Net spreads short voice messages through a web of trust; credibility decays until a threshold where the message is dropped.

Matrix Public Net comes with a program for recording and sending messages as well as plugins for XMMS and WinAmp that play received messages.

Extending the Blogosphere

This is a proposal for the extension of the Blogosphere, the network of Weblogs.
Individual Blogs are connected by their users implicitly: a community emerges, because users regularly read and comment on others entries. By making this connexions explicit, a web of trust is created which functions like a reputation mechanism.

The resulting system leverages the advantages of social networks for the distribution of news. It can be implemented as a decentralised system, with a simple extension to the Blogosphere.

The system is explained in a paper and in the presentation at the Mobile Entertainment conference in Manchester.

The RSS MPN-Interest module is the first part of this extension.

FrameMaker::FromHTML is a Perl class to convert HTML file to FrameMaker MIF.

SYNOPSIS

use base FrameMaker::FromHTML;

use strict;

my ($infile, $outfile);

$infile = shift;

($outfile = $infile) =~ s/.htm[l]*$/.mif/;

# Insert routine to validate HTML -- eg, use HTML-Tidy

# VERY important -- this script is fragile at any time

# but worse with bad HTML

my $p = FrameMaker::FromHTML->new($outfile) ;

$p->parse_file("$tempfile") or die "Parsing failed on $tempfile: $!n";

Use to convert properly formed HTML into FrameMaker MIF. Likely to be found buggy, particularly with funny HTML. Errors in MIF are usually flagged in FrameMaker console when FrameMaker is used to open the file.

See example file htmltofm.pl, which may be all youll need to get it working on some files. In which case, youll need to have HTML-Tidy installed to clean up your HTML.

maRBL project is a policy daemon for Postfix that lets you trigger any Postfix action as a result of an RBL match.

There are only a couple good, practical options for spam filtering, but none of them are 100% effective. Statistical filters can come very close to perfection, but at the cost of CPU time -- you cant filter something until youve received it and spent some time analyzing it -- and there are few good options for blocking hosts outright.

What about RBLs?
RBLs are simple, fast and efficient but they frequently have false positives. Theres an implicit level of trust required: you have to trust RBL administrators to add and remove hosts in a timely and accurate fashion from their lists. The problem is that only a fraction of lists are entirely automated, mosts have humans involved in the process, and humans are fallible. Worse, humans are vindictive, many lists go for collateral damage by blocking large ranges of IP addresses in an effort to arm-twist ISPs into being more responsive about their spam problem.

What about Greylisting?
Greylisting relies on the fact that most spam is no longer sent through real mail servers, and instead is sent from subpar SMTP engines. Greylisting forces senders to wait for a period of time and retry, something many of these engines are incapable of. The problems are that it fares poorly when handling mail from large ISPs that have SMTP clusters (theres no guarantee that the retry will come from the same IP address), that it introduces more delay to the process of receiving an email, and that occasionally you will run across non-RFC compliant mailservers that treat a temporary delivery failure as a permanent one.

mod_filter allows you to filter output from other modules inside of Apache. This allows you to implement filters (think Swedish Chef, jive, etc.).

You can also use it to retailer output for your locale. This works with HTML documents, mod_perl, PHP, JServ, CGIs, and for that matter just about any sort of custom handler you might have.

Everything we do online, what we browse, what feeds we read, what we search for, increasingly represents who we are. This "Attention Data" has real value and needs to be protected.

Until now, only companies on the other side of our clicking captured this value. AttentionTrust is a not-for-profit organization that attempts to place the user in control of his or her Attention data.

Attention Recorder is a Firefox extension that allows users to monitor their clickstream and browsing history. YOU alone are in sole control of this information, when it is stored locally on your desktop in an XML file. YOU alone can choose to share it with a service you trust.

AttentionTrust believes that you have the following rights to your Attention Data:

1. Property--You own your data
2. Mobility--You can copy or delete your data.
3. Economy--You can exchange your data with others your trust.
4. Transparency--You can see how your data is being used

rshaper is a Linux kernel module that limits the incoming bandwidth for packets aimed at different hosts.

While the former issue can be addressed with the conventional shaper driver, the latter cant be easily addressed by the standard shaper. As a matter of facts, I have not been able to use the shaper to address the former situation, either; this because effective filtering can only be achieved through source-routing, but when I had to deal with this problem, the shaper only existed for Linux-2.1 while my production setup was constrained to be 2.0. Moreover, with netfilter and rshaper the outgoing traffic can be shaped

While running rshaper with 2.0 and 2.2 requires patching the network driver, the 2.4 "netfilter" feature helps rshaper by avoiding the need to patch the netword driver.

CMS RSS Grabber is a system that grabs RSS feeds and fills the content of a CMS system. In other words, CMS content syndication through RSS
It is built in such a flexible way that it doesnt matter which CMS system it connects to. Settings inside the script let you define how you access the database.
Enhancements:
- An option to strip the http:// from the URL that is being exported to CMS.
- Usage is [$url=nohttp$].
- A CMS authors query is added to CMS Settings.
- Selection of author that adds content can be inserted with the [$authorid$] variable.
- Misc. variables for dates and time are added.
- An installation script is added for easy install.
- Settings for WordPress CMS are added.
- The ImportCMS() function didnt include the prefix to the feeddata table, imports to Joomla gave double texts in articles and the URLs had double http:// in them, and CMS update error messages were shown before logging into the system.
- These issues have been fixed.
