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 overlaps. I had to run a high-pass filter…
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 then seeing if the skew towards people…
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 either of those, or your 'geg' clue, which…
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.
> The gasoline produced from carbon is then intended for burn... If it's captured from the atmosphere and then burnt then surely it's zero-sum (apart from the energy cost of capture). Is this not better than releasing…
> That’s actually a huge opportunity though. If you have a small edge in information, you can make millions. Also, if you can act on public information faster than others then you effectively have that edge in…
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/100758754
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 you fire a beam of particles at…
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 articulating how they might perceive…
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 industry. However, last year they announced…
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 and so rapidly fall the other way…
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 proteins that glow under UV, but have…
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 ensure a candidate is really interested in…
Electronic piece of cheese! Symbian OS was very capable, full of features, but hard for developers to pick up and work with. I remember when the iPhone first came out and Symbian developers couldn't believe how few…
