The U.S. war on Iran is now estimated to cost $1 billion per day. Meanwhile Americans are told there’s no money for healthcare, hospitals, or basic social programs.

Helsinki just went a full year without a single traffic death The capital city is Finnish’ed with car-related fatalities.

β€œHelsinki hasn’t registered a single traffic-related fatality in the past year…Citing data that shows the risk of pedestrian fatality is cut in half by reducing a car’s speed from 40 to 30km/hr, city officials imposed the lower limit in most of Helsinki’s residential areas and city center in 2021.”

If Jeff Bezos could afford to spend $75 million on the Melania movie & $500 million for a yacht to sail off to his $55 million wedding to give his wife a $5 million ring, please don't tell me he needed to fire one-third of the Washington Post staff.

A bar chart showing the electricity use of several daily activities with the subtitle "The 'typical query' is not a useful way to think about coding agents' energy use." The bar for a 'typical ChatGPT query' is not even visible. My median Claude Code session is somewhere between the average US household per minute and toasting bread for three minutes. My median day with Claude Code is something like running a dishwasher.

Whenever I read discourse on AI energy/water use that focuses on the "median query," I can't help but feel misled. Coding agents like Claude Code send hundreds of longer-than-median queries every session, and I run dozens of sessions a day.

UX design so focused on optimizing for a given user task, while completely ignoring:

- goal achieved, i want to get back to where i was

- i want to immediately do goal again

- i want to switch to different goal

Way too many times is 3-4 clicks/touches just to... do more stuff with the same app.

this is a good reminder of how things that are shitty but have been accepted as normal and inevitable can actually turn out to be abnormal and evitable with some science, time, education and political will

Whenever I teach this, I like to remind my students that #rstats was informed by a lot of statisticians and NA means β€œI don’t know” so most logical tests and operators return β€œI don’t know”. x> 5? I don’t know. I have to know x first.

Yes, exactly. Each missing value is equal to itself and unequal to other values. In contrast, R's NA is neither equal nor unequal to anything, including itself

If students and post-docs are workers, then academia may have some of worst turnover rates in any industry.

Still on Rstudio but I have it on machine. Does it simply go via the diff or does it read the whole repo? We’ve been discussing Claude and codex but they don’t seem to respect ignore directories (e.g. data)

Jobs with biggest % decline in job postings include lots of creative jobs. And *biostatisticians* 😬

These are thought to be most impacted by AI. Great job everyone.

Best case: The President of the United States knew about a pedophilia ring and did nothing to stop it.

Medium case: He also used his office to protect the perpetrators.

Worst case: Because he was one of the perpetrators.
