Eric Flint Passed Away

We just heard the sad news that Eric Flint, our COSine 2020 Guest-of-Honor, has passed away. Eric was best known for his novel 1632 and the alternate history series it inspired. As a guest, he was lovely and generous (despite a reputation for gruffness that seems undeserved). He was also well known for inspiring and … Read more

COSine 2023 Status Report #1

At the end of 2021 we weren’t sure if there was even going to be a COSine 2022, much less a COSine 2023. For those who don’t know, on December 30th, 2021 the Hotel Eleganté was purchased and decided to no longer hold conventions! Fortunately, after a bit of bargaining, COSine 2022 went ahead and … Read more

COSine 2022 Participant and Panels

The list of panels and participants is now up on the web site! The schedule is actually (theoretically) done, but I am a little afraid to publish it this early since there are always a few changes as people realize that they are actually visiting their Aunt Hortenses at that hour and could they please … Read more

COSine 2022 Status Report #1

Last June we had to make the difficult decision to postpone COSine 2021. After that we put ourselves into suspended animation until such time as a vaccine for COVID was available and an appropriate supply of lemon-soaked paper doilies could be acquired. Well, the doilies arrived, and most of us have aching arms, so it … Read more

COSine 2021 Postponed

When you run conventions, you have to plan for various different contingencies. For 2021, we budgeted for the obvious: Zombies. Dinosaurs run amok. Zombies riding dinosaurs. The usual stuff. Unfortunately, we didn’t plan for a pandemic–extraterrestrial or otherwise. Build a giant underground research facility, they said. Have you even seen Resident Evil, we said? In … Read more

Photos from COSine 2020

Well, we all survived COSine 2020! I think it actually went really well–nothing important was burned down, and the people I spoke with seemed to be enjoying themselves–or were nice enough to lie convincingly about it! I intend to do a post with stats from the con (which were all good), but in the meantime, … Read more
