#Bitcoin - The whole market is up and #crypto has a high beta. This makes #crypto a very risky asset. When everyone else gets rich, you get even richer. And when markets crash, you are even worse off - just when you may need money most, chart @AllisonSchrager bloomberg.com/opinion/articles

#China’s #trade surplus is on track to hit a record this year, increasingly putting it on a collision course with some of the world’s biggest economies by aggravating an imbalance in global commerce and potentially provoking Trump – chart @economics bloomberg.com/news/articles/20

: I have followed a number of accounts recently. Some of them are through flipboard and others are private accounts. The toots from the flipboard account such as Flipboard UK (see image) are showing in my home timeline but still have the 'egg timer' sign and I am being asked if I want to cancel follow request. The other set of accounts (private) just have the cancel request with the "egg timer" and none of their toots appear in my home timeline. I was wondering if there is anything I can do to resolve this situation?

Some good news: the Barricades project website is up and running again:

barricades.ac.uk/

"‘To the Barricades’ is a collaborative website project that seeks to chart and compare the development of forms of popular contention and protest in Europe in the years 1815-1850 – from the final fall of Napoleon to the collapse of the revolutions of 1848."

🔴 🌍 How Colonialism Invented Food Insecurity in West Africa

"“There’s been this long-standing argument—and this is something that comes out of the colonial narrative—that parts of Africa have just always been food insecure because their agriculture, environments, or crops are inferior,” says Logan. But, as the data show, African farmers were knowledgeable and successful for thousands of years. Outside forces uprooted that security."

I may have posted this link before, but Matt Might's short visual essay "Illustrated Guide to a PhD" is a pretty reasonable starting model for what a #PhD contributes to the sum of human knowledge. matt.might.net/articles/phd-sc

My Fediverse Advice:

* Follow more people. No, even more people than that. Basically, if you find a real person and their posts are good follow 'em
* If you get a good reply to a post boost it. If you make a good reply to a post boost it. Replies are not visible in the feed unless you do this. As long as the post is an OK start to a conversation or interesting boost it.
* Write thoughtful replies. And if you put effort into a reply boost it or probably only the people tagged will see it.

German scholar Johann Albert Fabricius was born #OTD in 1668.

He produced several significant bibliographies, such as Bibliotheca Graeca, Bibliotheca Latina, Bibliotheca Ecclesiastica, and Bibliotheca Latina mediae et infimae aetatis.

🔴 📖 Four Points of the Compass: The Unexpected History of Direction

"The earliest surviving depiction of the four cardinal directions is found in the Gasur Map, a clay tablet from the third millennium BCE discovered in modern-day Iraq. It refers not to astronomical observations but meteorological ones: the four winds."

🔴 Sentinelese contacts: anthropologically revisiting the most reclusive masters of the terra incognita North Sentinel Island

"In terms of similarities, genomic studies reveal that the ancestors of the Asian clade migrated from Africa through India, entering Australia around 48,000 years ago (Sasikumar, 2023). Subsequent sub-clades, such as M31, migrated to the Andaman & Nicobar Islands around 37,000 years ago (Palanichamy et al., 2006; Barik et al., 2008), showing genetic affinity with the Burmese populace (Sasikumar, 2023)."

The projected average #compensation of CEOs at the 350 largest publicly owned US companies was $25.2 million. Meanwhile, the CEO-to-worker pay ratio was approximately 344-to-1, chart @bethkowitt bloomberg.com/graphics/2024-op

I updated my arXiv article "How much string to string a cardioid?" (again) arxiv.org/abs/2311.15101. It now has a new result. For a "nice" number (like a prime number) of points n in a circle of radius r (and any multiplicative factor a), the amount of string required is approximately 4nr/π! For instance, the examples above have n=83 and, say, r=5 cm. The sum of the lengths of the line segments is exactly 10cot(π/166)=528.331 cm. The approximation formula gives 4*83*5/π=528.394 cm. (There's a slightly more complicated approximation formula that works for any n.)
