What was the point of building Google AI if it’s just going to report changes in OPS as an absolute increase in “points” rather than percentage increases to its constituent slugging percentage* and on-base, JUST LIKE A DUMB JOCK *which is not a percentage

I liked it a lot better when the ML algorithms doing weird shit just had floating point values and matrices as intermediate values to puzzle over. The current state of affairs where the algorithms leave behind cognitohazards that drive human analysts insane seems bad.

has anyone tried to talk sense into the EA community on their own terms? e.g. 
- All lives have equal likelihood 
- You should expect to have been born in the far future if it contains trillions of lives 
- Ergo it doesn’t and improving the present maximizes utility

Building software on LLM’s is an exercise in dealing with the fact that, at scale, you cannot stop them from doing this. It’s a rare occurrence for any given person but also probably happening to someone somewhere at a rate of several times a second

The second strategic failure is that the American people (re)elected a worthless fucking moron like Donald Trump, who is boundlessly confident despite knowing nothing about anything and so asked the US military to do the impossible for no reason at all because he got lucky in Venezuela.

Those of you eager to serve wealthy MLB owners as volunteer Pinkertons won’t like to read this, but as usual Joe Sheehan nails the real problem:
Joe Sheehan: This trade is a microcosm of the real problem MLB has faced for decades. It’s not about haves and have-nots, but wants and want-nots. The Dodgers, and teams like them, want to win more than teams like the Tigers do, so they go out and acquire the Tigers’ best pitcher. MLB has built an entire labor strategy and media campaign around demonizing the Dodgers, when in fact it’s the Tigers who are wrecking baseball. You have to be through the looking glass to think the sport’s problem is the team that’s trying to win rather than the team that’s trading Tarik Skubal while sitting 2 1/2 games out of a playoff spot.

I am begging you not to believe gazillionaire baseball owners when they tell you Skubal going to the Dodgers means we need a salary cap. Competitive balance is not the reason they want a salary cap. They just want to spend less, and with more predictability, on total payroll. That is all.

This paragraph gave me an epiphany about Matty Y. It's not that he doesn't understand how politics words. It's that fundamentally, he doesn't understand *what politics is.*
What I would ask of everyone at the table is simply that they respect the diversity of America and the wisdom of trying to compete effectively across this vast and varied land rather than trying to cancel each other. And I would urge people whose passion in life is shifting public opinion rather than responding to it to find a different line of work than electoral politics.

More people need to read this. There is no such thing as a "historically accurate Odyssey," because the 'Odyssey' is not set in a real historical time. It is set in the mythic Age of Heroes, not the real-life Bronze Age. #Odyssey #Homer #classics kiwihellenist.blogspot.com/2026/07/odys...

History and the <i>Odyssey</i>
The Odyssey is not set in the Bronze Age. It is totally flooded with classical-era motifs, with a smattering of archaic touches.

I used to say that many successful people have access to a stratospheric level of self confidence that’s inaccessible to me. I still think that is right but lately I've noticed there’s another aspect to it. They are chumps, or at least profess to be in public.

The HN discussion around this largely about how it produces inconsistent output. The bigger problem here is that there's no evaluation of any kind. So even if it produced the same output reliably, there'd be no reason to think it's right or even useful, sometimes. danunparsed.com/p/hackerrank...
