Welcome to 4d2.org!
So it's come to this...you've met us
Since 2001, 4d2 dot org has worked to provide interested folks with free access to communication and collaboration services in a mixed Linux/BSD environment. We focus on technical transparency, user privacy and free speech, with a dash of anarchy, cypherpunk and retrocomputing for good measure (ask us about building a web server on a C64 or running NetBSD on an Amiga 3000).
After 10+ years subsidizing our activities with a commercial hosting service, then 3 years operating as a 501(c)3 nonprofit while choking on tax paperwork, we're back to our roots as a small self-funded service. It's simpler, we've had the good fortune to be able to afford it, and we're having fun doing it.
Hey! Free stuff!
- Want secure email without Google or Microsoft? Want to host your own website, learn to code, or explore a Linux/UNIX command line? If you would like a mail, shell and/or web account, please contact the admin (see bottom of page). We prioritize individuals and not-for-profit organizations.
- Want to chat and make voice/video calls in a private environment, away from data-harvesting corporations? You can sign up for a free Matrix account instantly, then goad your friends into doing the same. It's really pretty great.
- Want a complete suite of collaborative office applications secured with end-to-end encryption? Try our free CryptPad instance and be amazed.
- Scroll down to see a list of all our nifty public services.
Cool, so, what's the catch? What's your angle? Does this cost money in some insidious way? Are you a cult?
A cult? We wish! In fact, we hope that by providing these free services, we will encourage you to learn more about our perfectly normal new religious order, the Reformed Tertiary Quantum Church of the Ravenous Bugblatter Beast of Traal. Please send your best drawing of a $5 U.S. banknote and a stamped envelope addressed to your childhood self, into which you have screamed a detailed account of a time when your mother deeply disappointed you, to Six by Nine Online Services, PO Box 25751, Portland OR 97298, USA. You will receive a copy of our lavishly illustrated pamphlet
Four Hundred Twenty More Reasons to Be Deeply Ashamed About Your Body, Especially Those Parts Right There via telepathy.
OK, not really. We're just humanists trying to provide folks with access to technology for education and fun. Sorry.
