@Shpigford I just went through this. Export to Obsidian and then use Claude Cowork to ask questions of the entire corpus or specific notebooks.

evernote is doubling the price of my subscription to an arguably insane price, even for a PE-acquired business.
we've got 15+ years of docs stored there (huge % are scanned PDFs).
trying to figure out my move here.
i don't want another note taking app. i kind of just want a vault for dumping all our random document files (again, mostly PDFs) that's thoroughly indexed/searchable.
big caveat: needs to be also be easily shared with my wife.
wonder if there's something there from a biz perspective? 🤔

@BillSimmons Whomever is in charge of the NBA Playoff tv schedule is an NFL plant

@realmadhuguru @Google Awesome run Madhu!! You really changed the game there!
Enjoy some downtime, and when you’re ready to tackle the next thing….call me!!

I'm moving on from @Google.
I had the privilege of helping build two businesses from zero: first across Search & Ads, then Gemini.
Three years ago, OpenAI and Anthropic were in the lead. We built what it took to compete: the playbook for building AI models, the customer feedback flywheel, and the enterprise business. Gemini 3 was the moment those systems came together.
To the Gemini team: we went from underdogs to competing at the frontier. Keep pushing.
For now, I'm enjoying the emergent capabilities of some real intelligence at home - my toddler. She's been quietly shipping.

@petergyang Totally get this for “productivity” but chat is a great thought partner to riff with when exploring ideas, also use for deeper answers to questions, etc.
To me they’re apples and oranges.

People asked similar questions in the mid-90s like. Why would anyone want to watch TV or Radio on the internet?
We’ve solved media but 30 years later still haven’t brought money natively online.

I don't understand the premise that "agents must use stablecoins." Why can't an agent remember the 16 digits of a credit card? Sorry maybe I'm a payments n00b. Stablecoins have a lot of great use cases, but ecommerce shopping is pretty well optimized already for cards.

He enjoyed this season the most.
Anyone ever consider in '24 how much pressure they were under?? Outcome was great, but process was challenging.
Meanwhile in '26, no one expected anything so he could just play w/o pressure.
Which one seems more fun? Wouldn’t you consider this season a success?
But just breathing that has everyone trying exile him to Milwaukee??

Meanwhile in '26, no one expected anything so he could just go out there and play w/o pressure. Everyone admits he made a leap too.
Which one seems more fun? And why is saying that worth being exiled to Milwaukee??

@AshNicoleMoss TMac left Toronto to be “the guy”.
The J’s have been to 6 ECFs and win a chip. If that was an issue it would have shown itself before year 10.

for those who want full context — this is what is being discussed:

Tracy McGrady says Jaylen Brown is frustrated with the Celtics organization 😳 (via @VinceAndTmac)
English

on Jaylen Brown's reported "frustration" with the Boston Celtics:
"what T-Mac is alluding to is that the return of Jayson Tatum and him (Brown) no longer being "the guy" upset Brown (...) and that's an issue with the foundation of what makes this team successful."

The race between @stripe and @circle is ON.
It looks like Stripe decided it was cheaper to buy the infrastructure than build it from scratch.
In 18 months, they acquired or built every piece needed to move stablecoin payments end-to-end.
Each of these projects covers a different layer of the payment flow:
1. @Stablecoin → stablecoin issuance and orchestration
2. @privy_io → embedded wallet infrastructure
3. @Valora → mobile wallet and Web3 infra
4. @tempo → permissioned L1 payments chain
Stripe now owns every layer of the payment stack itself.
It's not surprising that Circle did the same thing.
They just started by issuing USDC first, then built the infrastructure around it.
Let's see which one can process more payment volume.

@AndrewDBailey Because the NBA optimizes for their broadcast partners and not their fans.

@WorldWideWob For every Celtics hater - take your moment. We got BEAT that series. It sucks, especially after the season we had. Nothing is guaranteed in this league. Celebrate you earned it.

@yohaniddawela Couldn’t they just use home price as a better proxy? Data is available too.

Google trained an AI to predict your neighbourhood's income by counting the coffee shops, bus stops, and high-rises on a map. Nobody told it what income was.
The model is called S2Vec, published this month by Google Research as part of their Earth AI initiative. It takes the built environment (every building, road, park, and business in an area) and converts it into a layered image. Three coffee shops and one park in a grid cell become pixel values. The AI then reads that image the same way a computer vision model reads a photograph.
The training method is the part that matters. S2Vec uses masked autoencoding: you show the model a patch of a city with chunks missing, and it learns to fill in the gaps. Show it a cluster of high-rise apartments next to a subway station, mask out a section, and it predicts a grocery store belongs there.
Do that millions of times across the globe and the model learns the deep spatial grammar of how cities organise themselves. No human ever labels a region as "financial district" or "suburban residential." The model figures out those groupings on its own from the geometry of what's built where.
The output is an embedding, a string of numbers that acts as a mathematical fingerprint for any location on Earth. Feed those embeddings into a prediction task and S2Vec can estimate population density, median income, and carbon emissions for regions it has never seen before.
On zero-shot geographic extrapolation (predicting for regions entirely absent from training data) S2Vec was typically the best-performing individual model.
It matched or beat satellite imagery baselines like RS-MaMMUT and outperformed GEOCLIP on socioeconomic prediction. The best results came from combining S2Vec with satellite image embeddings. Built environment data alone couldn't capture vegetation, terrain, or transportation patterns well enough for environmental tasks like tree cover and elevation. But fused together, the two modalities outperformed everything else.
The standard approach to geospatial ML has been hand-crafting indicators for every new problem. Predicting air quality meant building a bespoke feature set. Estimating housing prices meant building another one. S2Vec replaces that with a single general-purpose representation that transfers across tasks.
The training data is map features, not satellite pixels.
That distinction is pretty important to understand. It means: map data updates faster, costs less to process, and covers built infrastructure at a resolution satellite imagery can't always match.
A satellite sees rooftops. S2Vec knows there are three cafes, a pharmacy, and a bus stop underneath them.
Google's broader Earth AI pipeline now has three foundation models working in parallel.
1. PDFM for population dynamics.
2. RS-MaMMUT for satellite imagery.
3. S2Vec for the built environment.
Stack them and you get a system that can read a neighbourhood the way a local understands it.
