Spam Control For Postfix
Spam is a major problem for anyone with a mail server. Many times,
spam goes to email addresses that don’t exist. But, it still is hitting
your server even if it isn’t delivered. Other times, a users inbox will
be overflowing with annoying messages about Viagra, hookers, free
software, and whatever else. Below is a solution. It’s an ongoing accumulation of my efforts to
stop spam to the best of my abilities. So far, it has a 97% success rate
with over 20,000 emails (spam and ham, alike) processed.
Spicy Fedora 14 Adds New Linux Flavor
The Red Hat sponsored Fedora Linux community distribution is out this week with the first beta of the Fedora 14 release. The new distribution updates key applications and introduces new security and virtualization capabilities as well as support for the latest open source programming languages.
LibreOffice Is The New OpenOffice.org
Thanks to Oracle, not only is OpenSolaris now dead along with other open-source projects previously funded by Sun Microsystems now facing hardship, but the OpenOffice.org community has now decided to part ways too. The OpenOffice.org community has decided to launch The Document Foundation as a new, independent organization. The Document Foundation will now be backing "LibreOffice" as the brand rather than OpenOffice.org.
Uncluttered Minds Do Not Care…
There are no profound revelations here…at least not in this post. It just serves to reinforce something we already know.Chase, Ami and Zeneda are three fairly recent recipients of HeliOS Project computers, ages 12, 13 and 11 respectively. When we go into a home to give a child a computer, one of the first things we do is explain to them that we have installed Linux on their computer, not Windows. This announcement is usually met with even stares or shrugs. They don’t care…they are just jacked that they are finally entering into the tech age at home. Most times, any concern expressed is with the parent. Of course it would be.
Open Source Software Shortcut — Escaping SSH With ‘~’
One thing you may not know about SSH is that it has an escape character: ~. To try it out, hit return (the escape character is only picked up at he start of a line, so you must make sure you are) at the console in an active SSH session, then enter ~. Nothing will show on screen; so far so good. Next, hit Ctrl-Z and the session will be suspended — handy if you want to check something on your local box without logging all the way out of SSH. This trick will also work from within screen, and even from within mutt. To return to your SSH session, type fg and hit return.
Fedora 14 Beta Goes Live

Chrome 60 times faster
Google says its new Chrome version has some serious speed. Thought the limits of browser speed had already been reached? Perhaps not. Google now claims to have something even better up its sleeve. According to its Chromium blog the version 7 of the Chrome browser could get a healthy speed boost.
Tuxpaint: hook ‘em on open source graphics while they’re young
Tuxpaint is an open source graphics program that occupies a special niche: it is designed for children. This makes it a rarity in the software community known for every developer scratching his or her own itch. Tuxpaint has just six tools: paintbrush, rubber stamp, line tool, text tool, polygon tool, and eraser.
The "Free Beer" Hangover
A couple of days ago, I talked about Yahoo’s warning messages saying my system (Linux) had not been tested with their mail program and that resulted in a very impassioned plea to help a group of Yahoo Groups users to protest the changes that Yahoo has apparently made to the way Yahoo Groups work. Changes to the way mailing lists work are nothing new. I am a member of several Yahoo Groups. But I am also a member of a number of Google Groups and a mess of mailing lists running on Mailman. While reading the complaint, I had two thoughts.
The Launch of the Document Foundation and the Oxymoron of Corporate Controlled "Community" Projects
This morning brought the significant – and long overdue – announcement of the launch of an independent foundation to host development of the open source, ODF-compliant OpenOffice productivity suite. It should have happened ten years ago.
