@ankurnagpal If you are borrowing a few mil on an SBLOC, you can get something like SOFR plus 1.25%, which is currently around 5% and declining. A good strategy if you already have money parked in index funds— might as well use them as collateral!

A financial engineering trick used by wealthy people: If you have a large balance in your brokerage account, you can borrow money at US treasury rates (~4%) This is cheaper than a mortgage, and you can deduct the interest you pay as a capital loss! Here's how it works:

@nearcyan just crazy enough to work

What’s a live album that captures an artist at their absolute best?

@JoeLaz you totally made my day

For kicks, I asked AI to make a hype video for my LinkedIn profile.

I’m Shawn, founder of Memories.ai, former researcher at Meta and CS PhD at University of Cambridge. Today we’re launching Memories.ai: we built the world’s first Large Visual Memory Model - to give AI human-like visual memories. Why visual memory? AI to date is chat-based, which has great applications, but humans are not only chat based. Humans have visual-memories, and are visually driven. Memories.ai enables AI agents, softwares, and even robots to see and remember the world the way humans do. We just raised an $8m seed round led by @susaventures to build the visual-memory layer for AI. Why is Memories.ai so groundbreaking? 👇

What an exciting week for our friends at @playai! A massive congratulations on their acquisition by @Meta. This is truly a landmark moment for them and a huge validation for the innovative technologies they've embraced. We're thrilled to share that Vectara is the RAG-as-a-Service behind PlayAI's exceptional text-to-speech capabilities. Their incredible success with this acquisition underscores the critical role that Retrieval Augmented Generation (RAG) and Generative AI play in building impactful, scalable AI products. PlayAI's journey from a pioneering AI company to being acquired by a tech giant like Meta showcases the undeniable power and real-world applicability of a well-implemented RAG strategy. This is more than just an acquisition; it's a clear signal that #RAG and #GenAI are at the forefront of the next wave of technological innovation. Thinking about how RAG could elevate your next GenAI project? We’d love to be part of your successful journey: bit.ly/4lA0Lxj

Grok 4 🤝 YDC You know the drill: ask and you shall receive. @xAI’s flagship model is the latest addition in the you(dot)com toolbox. It’s ready for all your complex research questions, agentic workflows, and everything in between.

I said “walk and chew gum at the same time” in a meeting today, and the youngsters on the team thought it was hilarious—first time they’d heard that colorful idiom.

@bradsferguson um

Safety monitor was present and did disengage the system twice during my rides. Once when the car attempted highway access. Human oversight still essential.

Three days with Tesla Robotaxi. 62 total rides. Here’s what actually happened when I put the autonomous future to the test.

If you could name the first city on Mars, what would you name it?

@jeremyphoward @l2k @wandb RF has stood the test of time, Breiman’s paper was in 2001!

@l2k @wandb PS: This isn't a recent addition -- I was just reminded about it when I came across Lukas mention in this video, and realised I'd never actually said anything about this. :) Random forests are just so damn cool.

When I was optimising ULMFiT, I came up with a trick where I ran lots of ablations and fed all the hyperparams and results to a random forest. That told me which were most important. I told @l2k about it, and @wandb added it to their product! :D youtu.be/2QX6jjMt1Eg?si…
