Looks like the idea for this was based on a medium post by Brian Armstrong: https://medium.com/@barmstrong/ideas-on-how-to-improve-scien...
rorygreig··on One of Wall Street’s Most Popular Trading Strategies Is Now Failing
The fact that trend following strategies are becoming less effective could be interpreted as a positive thing implying that markets are becoming more efficient, as trend following shouldn't work in a completely efficient market.

Trend following strategies are pure market followers and are not based on fundamentals, therefore they do not bring any new information into markets and are unlikely to improve the efficiency of a market.

My understanding is that CTA is a general term for a hedge fund that uses trend following strategies, primarily trading futures, but not actually restricted to commodities, so it's not a particularly accurate name, just industry jargon.

There's an irony to this being an article from the Washington Post, maybe they know something we don't
rorygreig··on SoftBank Group and Saudi Arabia plan to spend $200B building a solar power plant
Does that include the energy used to pump the water after processing?

From what I understand the most energy-intensive part of desalination is pumping it to where people can actually use it.

Good point, I suppose "69%" accuracy doesn't actually mean that much unless you consider the odds.

I'm pretty sure I could predict Real Madrid vs. my local home town team with better than 69% accuracy, but that doesn't mean much

Apparently around a half of Deepmind's AI specialists are Canadian educated, so no surprises here.

There are also several places in Nova Scotia that speak Scottish Gaelic. A lot of the road signs in Cape Breton are in Gaelic
rorygreig··on ‘2001: A Space Odyssey’ rendered in the style of Picasso
I wonder how long it takes to render each frame.

Eventually with fast enough GPUs you could render a video game in this style, now that I would like to see.

They also spelled San Francisco incorrectly (San Fransisco)
rorygreig··on The true size of a country or state
I think it has been rotated to fit inside Africa better. If you spawn it by typing in USA it fits back after you drag it.

There's a Mythbusters episode where they make a boat out of Pykrete, it's pretty awesome.
rorygreig··on The world is not falling apart: The trend lines
Why is the fact that it's not self-governing relevant to the article? If the violence statistics cited apply to the (country/nation/administrative region/chunk of land) that is England, then surely that's all that matters.
