2 sides of changing std of care Me: If we change X, we can potentially reduce injury Y. If that became standard of care, you could get CPT/paid for monitoring X. MD: Yes, that would happen. Also, monitoring X would then also become required, so if you didn't monitor X, they deny pay/reimburse.

As promised, here’s my tax day rant. For 99% of taxpayers, the IRS already has the data to send you an almost fully completed 1040 for you to add a few pieces of data to, automatically recalculate, be done. It doesn’t because of Intuit.

“Helsinki 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.”

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. On my blog: www.simonpcouch.com/blog/2026-01...
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.

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.

I used to feel some type of way when people would write `library(tidyverse)` in #rstats scripts. I've written a lot of packages so it seems like a dependency hell (which it is for pkgs). Although introduces many dependencies for the script, I've come around to making scripts quick to make.
