Originally sent 12/7/2025

COSine 2026 will be January 23-25, 2026 at the Embassy Suites by Hilton Colorado Springs.

Only a bit more than a month and a half to go before COSine! Amazingly, things are starting to come together. You can see the (preliminary) schedule here, and also the list of our talented and charming participants, not to mention our main guests:

  • Cory Doctorow – Our Guest of Honor, the amazing writer, journalist and activist. He’s best known for his Little Brother series, and also for coining the term Ensh*ttification (and writing a book with that title. He’ll also be doing a panel about it at COSine). It explains why almost every interaction with technology these days has turned into a rage-inducing nightmare. Or is that just me?
  • Dr. Josiah Seaman – Our Science Guest of Honor, a Geneticist and Bioinformatician who also knows a lot about a lot of different subjects. He and Courtney have a really cool hands-on science panel planned.
  • Michael Carroll – Our artist guest of honor, Michael is best known as an award-winning space artist who literally has some of his art on Mars (in digital form) and is also an author and international teacher and lecturer.
  • Connie Willis – Special guest and Sci-Fi Grand Master. Everyone always looks forward to her panels at COSine, but I definitely want to hear what she has to say on the other of our rudely-named panels this year!
  • Courtney Willis – Special guest, the inimitable Dr. Science. As well as a big hands-on science demo with Josiah, he’s also bringing down some 150+-year-old sewing machines from his (large) collection, and is going to do a make-and-take panel where you can try them out!

Registering

Haven’t signed up yet? Register now, register often. Also, what better x-mas gift could there be than a membership to COSine? (Note: I’m just being told there are 197 better gifts. But still, top 200. Not bad.) Not sure if you’ve already registered? You can check using our online registration lookup tool.

It is also cheaper to buy a membership ahead of time than at the door!

Hotel

You can find details on registering for a room at our hotel, the Embassy Suites by Hilton Colorado Springs. You can also call them at 719-599-9100. Be sure to mention COSine to get the con rate (and so the con gets credit for your room nights :-).

If you have any problems with booking a room, please let us know (just send a message to info@cosinecon.org) and we’ll help get it sorted. Also, be aware—the con rate is only available until January 2nd, 2026.

Note: Due to the joys of the Hilton registration system (see discussion of Ensh*ttification above), some people, at some times, have seen better rates than the con rate. If you see one, you should definitely take it. However, if you could also let us know, we can tell the hotel and get credit for your stay!

Contacting Us

Feel free to ping us if you have any questions or issues, sequenced dinosaur DNA, alien tech, cool seashells, or any pieces of the Key to Time (willing to trade).
