Central Iowa Linux User's Group

Software Freedom Day

Kevin won’t know about a location until next month. We are still planning on the downtown Des Moines library, but they won’t take reservations until July. We should have enough Ubuntu CDs, so no need to download or order more.

Lightning Talks

Mediawiki

Wikipedia is founded on it. Frequently ties into MySql+. It can be set up so full users are added by admin, or allowed by admin. There is a discussion area for a page, and it can be configured to allow anonymous to discuss the page.

DNS based anti-SPAM techniques

Blacklists, SPF, Domain Keys

• Blacklists - addresses are added to a list, and addresses on the list are marked as spammers. Check out http://www.robtext.com/rbls.html or http://Mxtoolbox.com to see if your address is blacklisted.
• SPF - Sender Policy Framework. More at http://www.openspf.org.
• Domain Keys - Championed by Yahoo. Mail sent from Yahoo mail uses Domain Keys. Domain Keys is part of the e-mail header.

Some e-mail providers don't do the proper checks. For example, AOL will stop checking once it finds SPF or Domain Keys. So if a spammer uses these, you still get spammed. Some registrars/DNS providers don’t allow SPF and Domain Keys.

Open GroupWare - http://www.opengroupware.org/

An Exchange replacement. Uses PostgreSQL to store contact information.

Linux file and file system encryption

Ken was nice enough to put the presentation in a PDF.

OpenPBX - http://www.openpbx.org

Digg - http://www.digg.com

Digg was started by Kevin Rose as a place to submit links to tech related articles, and people discuss them. Similar to Slashdot, but user moderated, and when you "digg" an article, it gets stored in your profile so you can come back to it later.

Flickr - http://www.flickr.com

A place to upload pictures, join groups of people that share common interests, and share pictures with the groups.

LinkedIn+ - http://www.linkedin.com

If you are looking to find some old friends or colleagues, or perhaps looking for a new job, this is a good place to start.

For Digg, Flickr, LinkedIn+, and others, I would like to see a place where we could share our user IDs. Of course, this would need to be protected, so they don't get farmed by bots.

WPKG - http://www.wpkg.org

A tool to deploy software to Windows boxes. The configuration information is stored in 3 XML files: packages.xml, profiles.xml, and hosts.xml. These define the packages to deploy, profiles that define groups of packages, and what hosts to deploy the packages to.
