Thing is, the one Duran threw was a lot more like a sinker than a true four-seam. 14" arm-side, 8" IVB. Against 95+ but with IVB under 10 this year, Riley was a monster: .345/.621. His problems with heaters tended much more to be about getting underneath than being late. No room underneath 8 IVB.

The key issue to look for when we get the 3d Cir. decision is how it treats Ross' fair use defense insofar as it partially used headnotes materials to train its AI.

3d Cir. has ruled in favor of Thompson Reuters, finding that a competitor infringed their copyright in the headnotes on Westlaw, which the competitor partially used to train its AI. But the opinion is currently sealed so the parties can make redactions. storage.courtlistener.com/recap/gov.us...
UNITED STATES COURT OF APPEALS FOR THE THIRD CIRCUIT No. 25-2153 THOMSON REUTERS ENTERPRISE CENTRE GMBH; WEST PUBLISHING CORP v.

On consideration whereof, it is now ORDERED and ADJUDGED that the District Court’s order entered on February 11, 2025, is hereby AFFIRMED. Costs will be taxed against the Appellant.

BREAKING: The Third Circuit affirmed Thomson Reuters' win over ROSS, the first appellate ruling on fair use in AI training. Westlaw's headnotes sit behind a paywall. The court's reasoning now sits behind a seal. My quick take: copyrightlately.com/thomson-reut...

Signed, Sealed, Affirmed: Third Circuit Backs Thomson Reuters over ROSS
The first federal appeals court to weigh fair use in AI training sided with Thomson Reuters over ROSS. Why it did so, for now, is under seal.

Since the MLB playoffs expanded, we haven't seen nearly as many climactic Game 3s in the Wild Card round as fans have hoped — 11 out of 16 series ended in 2-0 sweeps. A couple years ago I broke down the math to explain why sweeps are, in fact, mathematically more likely than going three games.

AI's most valuable use case is for speeding up things that can already be automated, and using that efficiency to do more of those things--e.g., brute forcing scientific problems like protein folding.

Jokes aside, this is my real advice. If you're broke then, no, do not "be yourself." Your top priority is to show that you can be what they want to hire. Get that bag. If you have flexibility, then getting rejected for being yourself is *good*, that's not a place you wanted to work anyway.

This "systems thinker" vs. "transistor thinker" framing is interesting and troubling. Everyone wants to be a "systems thinker" now, which essentially means thinking big important thoughts and not sweating the details. But someone needs to sweat the details. And AI often gets the details wrong. Ugh.

Correspondingly, the AI promoter's position should not be "use AI or get left behind," but rather "if I don't learn about other professions and how they work, I will get left behind by those promoters who do." So... that's where I am at present.

The focus sees to be (1) Lane Kiffin is the kind of person who uses ChatGPT for legal advice, and (2) ChatGPT gave bad legal advice. But I think the real shocking thing here is (3) Lane Kiffin had conversations seeking legal advice from his lawyer friend and that friend is divulging it to ESPN.
BATON ROUGE, La. -- As LSU and the SEC found themselves locked in an unprecedented game of legal chicken over coach Lane Kiffin's plan to roster two former NFL players this season, Kiffin routinely reached out to his friend, attorney Tom Mars, for legal advice.

When Mars urged Kiffin to back down, the LSU coach texted him screenshots of legal opinions from an unlikely source.

ChatGPT."Usually, when I would express an opinion about what LSU was doing, Lane would reply with a screenshot from ChatGPT that supported LSU's position, which was almost always wrong," Mars said. "Lane ignored most of my unsolicited advice, but I don't think he'll be using ChatGPT anymore for legal advice."

If you're trying to defend a law against a claim that the law impermissibly regulates multiple subjects, it's probably not a good sign when the Court's opinion starts by saying "I-2066 impacts Washington law in several ways." www.courts.wa.gov/opinions/pdf...
