New York gets the better half of the weekend today: clouds and sun, low humidity and a high around 73°F, falling to 66°F tonight. Sunday turns humid, with rain becoming steadier and potentially heavier later in the day; use Saturday for anything that wants a long walk or an outdoor table. NWS forecast

Global equity funds lost a net $23.21 billion in the week through September 16, the largest weekly outflow in nine months. US equity funds accounted for $31.44 billion of withdrawals, their fourth consecutive negative week; Asia still attracted $6.26 billion. Money-market funds also lost $77.42 billion, while global bond inflows slowed to $855 million, their weakest since April. Reuters’ flow breakdown

The interesting counterweight is that sector funds gained $4.49 billion, led by technology, financials and consumer discretionary, and precious-metals funds took in $1.17 billion. This looks less like a single risk-off vote than a reduction in broad-market exposure alongside selective buying. The figures cover reported fund flows, not every investor balance sheet, and they arrive in a week shaped by the Fed decision and oil-price anxiety. Still, the regional and sector dispersion is more informative than the headline outflow alone.

A new paper by Julien Guyon and Léo Parent addresses a familiar source of model discomfort: parameters fitted to historical returns under the physical measure can be inconsistent with those needed to reproduce option prices under the risk-neutral measure. Their proposed mixed calibration works inside a path-dependent-volatility framework and tries to make the two views of the same process coexist rather than maintaining separate, quietly contradictory fits. Risk.net’s paper page, September 16

That is attractive because the division between P and Q is operationally porous. Forecasting, scenario generation and risk attribution draw on the historical world; pricing and hedging draw on the market-implied one. A joint fit may reduce the need for ad hoc reconciliation between them.

The paper’s title promises calibration robustness, not a free lunch. The tests worth looking for are stability through regime changes, the weights assigned to time-series and option-surface errors, and whether the mixed calibration improves hedging out of sample rather than merely producing a more harmonious in-sample score. The full technical detail is behind Risk.net’s access wall, so this is a paper to retrieve before forming a view on the implementation.

The report on Britain’s September 8 air-traffic-control failure is unusually specific. A high-priority flight-data request interrupted the routine allocation of an aircraft identifier—the four-digit “squawk” used by controllers—at exactly the wrong point in the process. The interruption lasted less than a millisecond; the resulting software state contributed to more than 2,000 cancellations or serious disruptions. The Guardian’s account of the report

NATS initially restored the system, then a second incident forced it to operate at reduced capacity for roughly six hours while controllers handled more traffic manually. The operator says safety was never compromised and found no malicious cause. It has put an interim mitigation in place while testing a permanent repair; the Civil Aviation Authority has opened a six-month independent review. Reuters, September 18

The failure is a useful reminder of what “legacy risk” can actually mean. The defect was not a slow machine or an unsupported language. It was an obscure interaction between priorities inside a system whose recovery procedure then became part of the event. Britain has now had three major NATS disruptions since 2023, so the consequential question is whether the fix removes this state transition or merely prevents the exact sequence that produced it.

Teleport spent three months using frontier models to search its code for security flaws. The operator report says 13 engineers found dozens of bugs and nearly twice as many high-severity problems in one quarter as the company had found across 2024 and 2025 combined. Those are company-reported results without a controlled productivity baseline, but the workflow lesson is more interesting than the headline count. Teleport’s engineering account

The team first built Conclave, a multi-stage system in which several agents generated, criticized and ranked findings. In practice, experienced security engineers using simple, targeted prompts often did better. One critical vulnerability began with an engineer giving a model a single file and asking it to solve a capture-the-flag challenge. As the models improved, finding plausible problems became easier; human verification and deduplication became the bottleneck.

This is a catch-up artifact from August, resurfaced this week by Simon Willison. Its value is the negative result. More orchestration did not automatically produce more useful security work. The scarce part became a skilled person who could choose a tractable boundary, distinguish an exploit from an alarming story and turn the finding into a repair.

Astronomers examining 20 tidal-disruption events—stars torn apart by supermassive black holes—found radio evidence for two periods of outflow. Jets appeared while the black hole was feeding rapidly, then reappeared hundreds or thousands of days later as the feeding rate fell to roughly 2% of its maximum. The Guardian’s report on the Nature Astronomy study

That second threshold resembles a transition already observed around stellar-mass black holes. If it holds, the same accretion physics is operating across an enormous range of mass, with the clock simply running much more slowly around the larger object. It also gives observers a better idea of when to return to an apparently quiet event: the late radio signal is part of the process, not astronomical aftercare.

“Wendell Castle: Living” opened Thursday at Friedman Benda and runs through October 17. Rather than putting Castle’s biomorphic furniture into a white-box chronology, the gallery has reconstructed rooms from the converted mill outside Rochester where he lived with the ceramic artist Nancy Jurs. Their daughter Alison co-curated it. The Financial Times visits the exhibition

Castle’s stack-lamination technique—building up thick layers of wood, then carving them—made furniture that could swell, curl and balance in ways conventional joinery discouraged. The domestic setting should make the work more legible: the 1962 music stand, 1964 walnut stool, a wonderfully improbable 1973 coat rack and the later Arcadia settee were used among books, ceramics and ordinary life.

This is a good Saturday art-and-design stop because it asks a pleasurable question: does sculptural furniture become stranger or more convincing when somebody actually has to live with it? The reconstructed house is necessarily an argument, not time travel, but it restores scale and companionship that isolated auction photographs remove.

Jake’s Dilemma will close October 18 after 30 years on Amsterdam Avenue. The bar says it lost its lease; neighboring sibling the Gin Mill remains open. Eater’s direct neighborhood report

This is not a dining recommendation, just a meaningful bit of neighborhood turnover. Jake’s belonged to the UWS category of capacious, unprecious bars where generations of Columbia students and twenty-somethings could arrive without a plan. A month’s notice at least gives regulars a chance to say goodbye before another long-running room becomes a recollection with a liquor license.

In an early scene from Who Framed Roger Rabbit, an animated pelican cycles through a live-action studio lot. The production did not animate the bicycle. The crew put a real one on the ground, filled its wheels with water to give it stability and pulled it along a hidden cable; the pelican was drawn in afterward. The production detail and original clip

It is a tiny, delightful example of effects work choosing the physical solution where it would look best and spending animation on the impossible part. The shot lasts seconds. Knowing how it works makes it more charming, not less.

The artist presale for Hamilton Leithauser and Rostam at Music Hall of Williamsburg on November 9 and 10 opens Monday, September 21 at 10 a.m. ET; general sale is Wednesday at 10 a.m. The November 9 listing gives 7 p.m. doors, an 8 p.m. show and an 18+ policy. Exact AXS event page

Prices and selectable inventory were not visible before the sale. The November 9 show is the first one to try; the following night is the natural fallback. The attraction is still the tenth-anniversary performance of I Had a Dream That You Were Mine in a room appropriately smaller than the songs sound.

Titan has introduced Vetra, its first branded in-house mechanical movement, in a new automatic-watch collection starting at ₹47,995. The announced 7A architecture is more interesting as an industrial step than as an immediate purchase: one of the world’s largest watchmakers is putting its own mechanical calibre, rather than quartz or a sourced automatic, at the center of a relatively accessible line. Launch details, September 18

The available report is thin on tolerances, serviceability and independent timekeeping tests, and I found no verified US availability. So this belongs in the watch notebook, not the shopping list. The next useful evidence is a movement teardown and a clear account of which parts are actually made inside Titan’s system.

Kyler Murray is out against Chicago under the concussion protocol, so Carson Wentz will start for Minnesota. Wentz went 12 of 19 for 133 yards and three touchdowns after replacing Murray last week, when the Vikings erased a large deficit against Green Bay. That production came in a very particular game state; it does not make him a plug-in equivalent for Murray’s rushing and improvisation. Reuters, September 18

For Atlanta, Cooper Rush remains the starter against Carolina while Michael Penix Jr. is out. Rush’s opening line—143 passing yards, one touchdown and two interceptions—helps explain why Drake London finished with only two catches for 29 yards. London’s talent has not changed; the distribution of catchable volume has. Atlanta quarterback update

Those are the two checks to carry into Sunday lineups. Wentz raises uncertainty around Minnesota’s play design and target distribution; Rush lowers the comfortable floor for Atlanta’s passing options until the offense proves it can sustain drives.

BETTING — PASS. I investigated the Sunday NFL slate, but the quarterback and final-injury changes were still moving the relevant assumptions, and I could not pair a documented independent win or cover probability with a timestamped, executable FanDuel or DraftKings price. There is no responsible numeric entry point to print from stale public listings.

Boy Harsher released GET MEAN yesterday. Start with “Hard Beat”, the cleanest test of whether the record’s severe synth-pop and physical pulse belong in your weekend.

The duo frames the album around love, loss, survival and redemption; the 12-track record runs 39 minutes, short enough to remain an album rather than a research project. Official album and credits

This lands close to the darker end of the Chromatics/LCD axis without sounding like a tasteful imitation of either. The draw is the tension between Jae Matthews’s cool vocal presence and music built to move a room. If “Hard Beat” works, continue straight through rather than cherry-picking the singles.

Apple TV Store rental in the US; 99 minutes. David Robert Mitchell directs Anne Hathaway and Ewan McGregor as parents in a 1982 American suburb whose neighborhood is displaced by a cosmic anomaly. Familiar streets begin to collapse across time, and the mystery eventually admits creatures large enough to move the film from suburban unease into pulp adventure. Rent on Apple TV

This is the Saturday choice if you want atmosphere and an actual story without committing to a season. Mitchell’s premise offers the architectural uncanniness of an ordinary place becoming unreliable, while the 99-minute runtime keeps the genre machinery moving. The caveat is price and tone: the current digital rental has been listed at $19.99, and this is ultimately a family-and-creature thriller rather than an opaque Under the Silver Lake cousin. Current digital-release details

If premium rental pricing feels faintly absurd, wait for the subscription window. If the premise is exactly right for tonight, it is compact enough to justify treating the rental as the evening’s outing.
