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 the words, so the distraction questions are mostly moot

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 cards then gradually transitions to "x" and

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 $0.24 at the API rates.

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 clearly not thinking 70 years into the future to stop automobile

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, teamsters, lashing their horses, had clogged the road

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).

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 are willing to listen to much more sophisticated storie

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 compilation speed. There's just a lot less inp

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 have been fantastic, with our largest compilation units getti

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 already has. The google build tooling team got modules to most

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 underground bunkers and volcano lairs.

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 interested in transportation and wanting it to work wel

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 say you care about snow driving and want to see that co

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-automated version, and they differ in how much notice t

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, private tech project to what you wished public transit look

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 those promoting math excellence. That's not to say there i

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 the box and it would recognize the symbols and take

I've been doing this for the past 2 years with my two older kids (now 5.5 and 3.5) based on the same reddit post this article is about. I've found it works great, though I have high-focus kids. I call it "word cards". Fo

But isn't that the "relative" point? A house in Santa Clara doesn't cost $1.4M because it's 3x better than a house in another state, or costs 3x as much to build. It's because there are a lot of other high-sala

What's the trigger for all the diffusion video projects this week? Are they all at the same conference, or did one trigger everyone to rush to publish? I'm grateful but curious. Animating still pictures from my kids' books is
