Getting more difficult to find a job

2025-09-17 17:17:43

For the Washington Post, Taylor Telford, Jaclyn Peiser, and Federica Cocco report on job numbers, listings, and unemployment, which have not looked favorable for many over the past year.

Hardly any corner of the economy is untouched by jobs cuts and slowdown: Employment in all goods-producing industries slumped in August, with the deepest losses coming from manufacturing and mining. The service sector was racked by steep layoffs in business and professional services and IT.

My general feeling is that data folks have seen better days, which seems to be part of a broader trend. Hoping things start ticking in the other direction.

Explaining the true size of Africa, a lesson in map projections

2025-09-17 16:25:59

For Reuters, Mariano Zafra and Sudev Kiyada highlight the true size of Africa and use the opportunity to describe map projections with handy illustrations.

You would think by now, after many maps, illustrations, and interactive graphics, we would have a better intuition for the pros and cons of different map projections. But then the African Union wouldn’t still need to campaign for anything other than the Mercator projection.

What people use ChatGPT for

2025-09-17 01:38:42

OpenAI released a study of how people are using their chatbot.

Patterns of use can also be thought of in terms of Asking, Doing, and Expressing. About half of messages (49%) are “Asking,” a growing and highly rated category that shows people value ChatGPT most as an advisor rather than only for task completion. Doing (40% of usage, including about one third of use for work) encompasses task-oriented interactions such as drafting text, planning, or programming, where the model is enlisted to generate outputs or complete practical work. Expressing (11% of usage) captures uses that are neither asking nor doing, usually involving personal reflection, exploration, and play.

A relatively small percentage is for programming and even less for data analysis. Writing and how-to queries take the majority, which I can only assume is mostly for LinkedIn posts.

Shrinking box office

2025-09-16 18:16:25

This summer was supposed to be a return to pre-pandemic levels of movie-going, but that was not the case, as shown by Christine Zhang and Brooks Barnes for the New York Times.

I’m into the movie poster as stacked bar geometry. Now do it with streamgraphs.

Seeking dividends over long-term investment

2025-09-15 17:07:15

There is a growing trend among investors to put money in places with high dividends. They prefer money now over decades from now. However, the higher dividends come at a cost in the longer term. For Bloomberg, Denitsa Tsekova and Vildana Hajric, with graphics by Armand Emamdjomeh, discuss the trade-offs that make the money-now approach seem less favorable.

The current wave of interest is new enough — and many of the followers young enough — that it has been easy to ignore how the most popular funds have often lagged basic stock indexes and threaten to eat away at long-term returns. Samuel Hartzmark, a professor of finance at Boston College, has researched the issue for more than a decade and has found that investors tend to fall for the “free dividends fallacy,” treating them and capital gains as separate. A 2015 paper of his finds that investors prone to that bias have a preference for funds that report boosted dividends even if they don’t improve overall returns.

There is a scrolling chart at the beginning that compares returns with different strategies over time. At first, I wasn’t fond of a non-zero baseline on an area chart, but technically it’s a difference chart with a baseline that indicates the starting investment. I guess I’ll let it slide.

Epstein inbox and a spreadsheet of gifts

2025-09-12 17:29:50

Bloomberg gained access to an email cache from Jeffrey Epstein’s Yahoo Mail inbox, spanning two decades between 2002 and 2022. They highlight the relationship between Epstein and Ghislaine Maxwell and how the timing and nature of the emails reflect a closer timeline than Maxwell has suggested.

The cache also included a spreadsheet from Epstein’s accountant that lists gifts and payments, such as watches and massage lessons. Bloomberg charted three years of transactions with a bubble chart over time.

It’s only a fraction of Epstein emails, as he used multiple addresses over decades, but it’s quite the digital trace. Find more on how Bloomberg verified and analyzed the cache here.
