Here's a playlist of the best punk songs of the past month. I also wrote a blog about the entirely expected lack of punk representation in big year-end lists.

(inspired by @marissarmoss.bsky.social' analysis of how country music is faring in prestige music media SOTY/AOTY coverage)
playlist: the best punk songs of november 2025
Some thoughts on big year-end lists, plus a punk and rock'n'roll playlist of garage punk, power pop, hardcore, and more.

Ironic memes about the "We Are Charlie Kirk" song, Kirk faceswaps, and Nazi occulist brainrot have collided on TikTok and things are getting very, very dark very, very fast. Your kids are watching nazislop on TikTok.

is it time to reëxamine the New Yorker’s antihyphen style?
When a cancelled performer reënters the culture, we expect them to offer us a great work, channelling their newfound clarity into the finest art they’ve ever made. With his new comedy show and début novel, has Louis C.K. met the bar?

Louis C.K.’s Next Chapter
In a new standup special, and a début novel, the comedian navigates murky, post-#MeToo terrain: not quite exiled, not quite welcomed back.

OpenAI says they aren't liable for the suicide of a user their chat bot urged to kill himself because suicide is a violation of the TOS
Additionally, OpenAI argues its not liable because Raine, by using ChatGPT for self-harm, broke its terms of service

This year explaining regression to the mean took forever but I’m sure next year will be better.

JK Rowling got a full *decade* of press as a martyr for being "cancelled" (declared passe by people online) and meanwhile nobody considers it very interesting that a prominent left wing author is basically banned from entering or publishing in the United Kingdom for her politics
so this is like, one of the biggest free speech infringements by a western democracy in our lifetimes right?

Not really the point, but it's a bit weird to say that Bayes can be 'gamed' by choosing priors to support your conclusion. I mean, how is that gaming? Where's the subterfuge? Do we not make fun of villains who elaborate their plans to the viewer?

don't be mystified. it's just log probabilities. log probability -> "information" / "surprisal".
S-Values are much more interpretable than P-values, yet adoption seems near impossible. I wonder what it would take to make the leap? #statssky #episky #rstats #statistics

this .Rmd supplemental material loads MASS after tidyverse and then uses select(). did they even run it?

The 1993 mid-handoff moment between shoegaze and Britpop has always been one of my hyperspecific musical sweet spots. Zach does a tremendous job here capturing both that moment and probably the greatest album it produced.
For this week's Sunday Review, I went long on one of my favorite albums of all time: Giant Steps by the Boo Radleys.

Jeffrey Goldberg's editorial leadership has been a disaster for the human race
Over many interviews, Robert F. Kennedy Jr. told Michael Scherer about how he plans to remake America’s public-health system. Can he lead the scientific establishment he’s spent much of his life crusading against?

What a goddamn legend. Every big tough conservative masculinity guy has been crying about how terrifying cities are to live in for the past two years and now Trump wants to move back to NYC
Reporter to Trump: Would you feel comfortable living in NYC under a Mamdani mayoralty?

Trump: "I would. I really would. Especially after the meeting, absolutely."
