Post-Game Win Expectancy (PGWE) for Wild Cards.
Patriots 98%
Rams 79%

49ers 60%
Bills 47%
This formula asks "based on the underlying stats of this game, how often would we expect Team X to win the game?"

Concise explanation of the consumer experience in the 2020s. It's analogous to how the internet is different for everyone these days.
The whole recent dynamic of consumer-facing businesses that exist due to capturing a large % of rich consumer spending and then offer some capacity and a worse experience to non-rich consumers leads to a lot of societal tension.

i think one of my hotter takes is that we don’t need a bigger LLM context for continual learning, we just need better recall over the context we have
subagents = stack
files = heap
we got gobs of context space already

One of the major uses of Claude Code is to build Claude Code and to create a bunch of skills and tools and config for Claude Code. It is a tool that is constantly being used to improve and extend itself.
This makes it a type of emacs.

The "Coverage Sack" was a myth in 2025.
Forcing the QB to hold the ball longer actually led to WORSE defensive results.
When QBs held past 2.9 seconds, the defense wasn't winning with coverage—they lost to the scramble drill.

If the jets aren’t gonna play any semblance of respectable defense, then I say punish them. Hang 8 touchdowns on them and force your division rival to sit with that in the record books for all time.
No mercy. Pats aren’t winning the Super Bowl anyway. Make this count.
