Lately I've been using RSVP (rapid serial visual presentation) speed reading, where you see a single word at a time, reading at 400-600wpm. You have to pay attention or you miss th…

DragonBox Algebra has a similar concept but gamified. It has a cool progression: you get a new "power" each chapter, like factoring or negating. And it starts out with monster card…

Yes, Gemini is very token efficient at video. It also has "lower resolution" options which can make it even cheaper if. With Gemini 3.1 flash lite an hour of video works out to $0.…

What conclusion do you think I was drawing? I was just sharing an interesting quote relevant to the thread. Oil was solely a lighting product at this point. The Teamsters were clea…

No idea about them trying to ban automobiles, but oil pipelines were invented to get around their friction. From _The Prize_, referencing the mid-1800s: "From the first discoveries…

The donation was also made through a donor advised fund (DAF), which means Musk didn't legally make the donation. I'm surprised he didn't lose on not having standing.

We do support YouTube Music and actually supported that before Spotify. But we only do ad-supported on Spotify and iHeartRadio (also paid Spotify).

Making my own epub reader with the kitchen sink of features I'd like. It's a speed-reading app first and foremost, using RSVP (rapid serial visual presentation, one word at a time)…

My personal project is illustrating arbitrary stories with consistent characters and settings. I've rewritten it at least 5 times, and Nano Banana has been a game-changer. My kids …

This was in place of reorganizing the codebase, which would have been the alternative. I've done such work in the past, and I've found it's a pretty rare skillet to optimize compil…

Clang modules. Sorry, didn't realize the distinction!

We use c++ modules at Waymo, inside the google monorepo. The Google toolchain team did all the hard work, but we applied it more aggressively than any team I know of. The results h…

At Waymo we use c++ modules via clang and got the demanded 5x speedup. As the article mentions, you need a close relationship between the compiler and build system, which Google al…

> “While TBD Labs is still relatively new, we believe it has the greatest compute-per-researcher in the industry, and that will only increase,” Meta said. Well, two ways to make th…

And imagine a hypothetical project that's 75% excavation. It'd never be built today, but if excavation gets cheaper the project could be feasible. And then an explosion of undergro…

As a counter to your one example: I've worked on autonomous vehicles for 16 years and my largest philanthropic effort is improving public transit. The common theme is being really …

The paper under discussion only considers human accidents in similar environments to where Waymo operates. So it's only making a claim about like-for-like driving. You could still …

What you're describing is L4. L4 is fully autonomous but with limitations on where/when it can operate. Level 5 is that but without restrictions. Level 2 and 3 are the mostly-autom…

I think you may mean Level 4. The difference between 4 and 5 is that 5 doesn't have any territory/environmental constraints, but you said you don't mind those.

Your link literally says the opposite. Sales dropped from 2023 to 2024.

But the Bakersfield/Merced HSR line is an actual project, estimated at over $30B (it makes no sense independently but is part of LA-to-SF). You seem to be comparing an actual, priv…

We started January 2009.

FYI that article is an interview with Jo Boaler, the main architect of removing middle school Algebra in SF and California (attempted). Her views are pretty controversial among tho…

What's your evidence that it would crash without the remote operation, or that it's more than 1.0 people?

I built my kids "the box", which had a similar concept. It was an upholstered box with a frosted acrylic top and a camera mounted inside facing up. You would put cards on top of th…
