TFW an author has done just enough research to get things spectacularly wrong.

Either yesterday or this morning. Who can remember that far back these days?

One of these is a real textbook and the other is a gag gift that came hollowed out with a flask of whisky in it.

I have such a hard time getting rid of old textbooks. They cost me a fortune. An who knows when you'll need to look up something on the empirical stability rules for atomic nuclei, reflectometer theory or stellerator equilibria :-/

Thanks for this, it's really great!

One apparent typo: the "key findings" in section 9.2 appear to have gone missing.

It feels like 2000 was a dividing line. Maybe a lot of people were disappointed about the lack of hoverboards and flying cars and started looking back?

As someone who came of age in the 80s, I don't recall much nostalgia for the 70s (bellbottoms, disco!) or the 60s (war, weird!)

Same data again, but in a new Elastic projection I've been experimenting with that avoids disintegrating Australia.

Map of the world's oceans in an as yet unnamed, experimental Elastic projection showing vessel presence according to AIS between 2017 and 2021.  This projection has Antartica in the middle and most of the world's coastlines are projected onto the edges. Unlike the Elastic-2 projection, Australia is recognizable as a continent. The areas around Antartica and near the north pole are mostly empty, but the rest of the map has many vessel tracks.

Fans of koalas, poisonous snakes, the Divynils or other Antipodean stereotypes will be pleased to hear I'm working on a projection that is similar, but doesn't disintegrate Australia.

You always have to sacrifice something when you make a world map. In this case, it's Australia.

It got ripped in half and smeared along the edge. You can see that better in this map where they show the land: kunimune.blog/wp-content/u...

It turns out that the Spilhaus projection exaggerates the size of the Chinese coastline quite a bit. There is a similar projectioin, called Elastic-2, which is better in this regard. See: bsky.app/profile/tim....

Same data, but now plotted in the Elastic-2 projection described at kunimune.blog/2023/12/29/i.... This reportedly has less area inflation around the East China Sea, and we do see that the vessel traffic in Asia appears less dramatic.

I need to do a little clean up on the repo I'm using before I open it up–I'll try to do that in the next few days–but in the meantime, I used the projection code from github.com/rtlemos/spil... to do most of the work. My main contribution was convincing Matplotlib to do backgrounds in a way I liked.

@paulwoods.io @davidkroodsma.bsky.social I played around with this over break and managed to map vessel presence in the Spilhaus projection. It really shows how little vessel traffic the southern oceans have.

It's also a good candidate for a black light poster with this color scheme.

I just completed all 25 days of Advent of Code 2024! #AdventOfCode adventofcode.com

Ugh! Day 24 was kind of brutal, but finally saw the trick of it.

I've completed "LAN Party" - Day 23 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/23

I was handicapped by a complete failure to follow instructions, but eventually–after taking a break to shovel a few tons of gravel–saw the light.

I've completed "Race Condition" - Day 20 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/20

This one was fun and had a closer to uniform difficulty between the parts. My solution was more general than it needed to be, but still ended up running decently fast.

I've completed "Warehouse Woes" - Day 15 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/15

Today was nice and straightforward, softening us up for some gruesome puzzle tomorrow I imagine.

I just got $10 in the Equifax settlement⁉️ As paltry as that sum is, I suspect that this may be the high point of data breach settlements and it's all downhill from here.

Are you good at cursing? The borrow checker requires a constant stream of profanity to make it work.

I've completed "Restroom Redoubt" - Day 14 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/14

🥶 That involved more ad hoc fiddling that I prefer, but hey, it's done.

I've completed "Claw Contraption" - Day 13 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/13

Ugh! This was the first day where I really wandered off on the wrong track. I kept thinking about doing it the right way, but was continually seduced by a flashier, but wrong, approach.

Blasting "Operation: Mindcrime" while reviewing code: good idea or the worst idea?
