Yes you're right it was a 2D cross-correlation which is very analogous to a convolution

That's exactly how it worked, hand rolled FFT and filtering following the method in "Numerical Recipes for C"

Interesting to see something like this! My computer science masters thesis was based on the same goal. I used a 2D convolution which meant you can merge images with inexact overlap…

My partner and I regularly disagree on blue vs green as the colours become more of a gray colour - might be interesting to randomise the brightness of the colours being displayed t…

I did exactly the same thing a few years ago - now it feels like a pull service that I'm in control of, instead of a push service with an algorithm controlling the content I view.

Correct!

I've been attempting cryptic crosswords for 20+ years and this is a great answer. My favourite clues: Die of cold (3-4) hijklmno (5) All the tips you've given won't help with eithe…

I couldn't agree more. In these difficult times this has given me hope both in terms of the state of humanity and also in the future of the internet.

Are atmospheric CO2 levels rising to an extent that currently projected levels would have a noticeable effect in the same way?

Also if you don't want to sail your boat across an ocean you can sail it into a big boat with a load of other boats and just collect it at the other side! https://www.cnbc.com/id/1…

The Picton ferry between the North and South islands of New Zealand does this too. https://en.m.wikipedia.org/wiki/Interislander

The femtobarn is a unit of area. The inverse femtobarn is basically saying the number of interactions "per femtobarn". A higher value means more interactions are occurring. When yo…

I read Children of Time by Adrian Tchaikovsky recently. Quite a lot of the book is told from the perspective of some highly intelligent spiders. The author makes a good attempt at …

Norway seems to be progressive and open-minded about this kind of thing. They have a massive sovereign wealth fund which has built up on the back of a successful national oil indus…

About 2 years ago I unfollowed all my friends. When I login there's nothing to see now. I feel that I've switched it from a push to a pull service and am much happier using it.

That's my experience too. If you very slowly lean to one side then you can start the turn that way. Countersteering moves the bike to one side which means you're no longer balanced…

Agreed. Scorpions also glow under UV light and scientists don't seem to have come up with definite theory explaining why this may be. Maybe these are just random occurrences of pro…

The tersorium/stick the Romans used is the source of the expression: to get "the wrong end of the stick"

That was a fun little interlude - I wonder how effective strategies like this are? Is it to check for genuine technical ability, engage candidates or just a little barrier to ensur…
