William Lyon Mackenzie King was a sexually repressed, hypocritical, guilt-ridden, prostitute-visiting momma's boy who was exceptionally weird. He was also, perhaps, Canada's greatest prime minister. This week, Evan talks about legacy, and about how you don't need to be a good person to be a good politician.

I was going to tell a science fiction story about faceswapping, and mass blackmail. Then the news broke about unethical faceswapping videos, and software designed and marketed for creating them: and I realised the future had arrived faster than I thought.
(This was originally a talk given at An Evening of Unnecessary Detail earlier this week, but I managed to mangle the audio recording settings, so I rerecorded it in a muddy park! It's not the same without the audience, but hopefully it's close enough.)

I'd never heard of moiré effect beacons until I got an email asking me about them. It seemed like a really clever idea - but it was really hard to research. Or at least it was, until I stumbled upon one magic phrase that revealed its history.
It turns out this thing's called an "Inogon leading mark" or "Inogon light" -- Inogon, not Inogen -- and it's a Swedish invention from the 1980s. But there's still a question: why is being used to mark an undersea cable, instead of guiding people home?
(Full disclosure: there were some weird strobing effects from the light that only showed up when I got the footage into the edit, so the image you see here has been digitally stabilised so it appears the same way on screen as it does in person!)
