Folks outside SF/F don't know that Asimov was a sexual harasser because while he was alive fandom thought it was cute (up to and including Asimov being invited to give a lecture on "The Power of Positive Posterior Pinching" at Worldcon, which he, wisely, declined).

The 68NC040 was a version of Motorola's 68040 that lacked an FPU, MMU, and CPU - and came in a convenient weight-saving package that also used almost 15% less power.

Finished up Tornus this weekend! Pushed myself super hard on this one with nmm and lighting. I really wanted to try to do my best to hit display quality for the first time, and I'm really proud of how he turned out. 💙

Science culture matters, but what is it? How can we reimagine and renew the relationship between science and society in the current malaise?

My colleagues at Actua asked me to write a paper to spur discussion. I wrote three. 🤷🏻‍♂️

1. Reimagining Science Culture in Canada.
