teichman··on Building a real-time AI tutor for 5-year-olds
Personally I would like to see kids learn way way more in much less time, and it’s clear AI is going to make that possible. What you are saying sounds a lot like “I want kids to learn less and be dumber”

I deeply wish I had AI-accelerated education growing up rather than sitting bored out of my mind while a teacher lectures at the bottom quartile

This is so cool!

Ignore the haters, AI accelerated education is so obviously a gigantic win for everyone. (And massively levels the playing field.)

If you like this site, check out (a) 3Blue1Brown's youtube channel for intuitive visualizations of (otherwise) hard math topics, and (b) the book Infinite Powers, for more calculus intuition + history.

Both are outstanding.

teichman··on The Startup That Built Google’s First Self-Driving Car
Generally, I agree with your sentiment regard proper accreditation in the media, but claiming that Thrun doesn't deserve a huge chunk of credit for self-driving cars at Google is thoroughly unsupported by the evidence (check out the history of the DARPA challenges). This article seems to be grasping at a sinister story of a coverup that simply doesn't exist.

From the article: "From then on, we started doing a lot of work with Google," says Majusiak. "We did almost all of their hardware integration. They were just doing software."

Just software? Holy cow. The machine learning, control systems, mapping software, and all the other algorithms in a self-driving car are the really fundamental pieces. It's super important to get the hardware right, and 510 did a great job of that, but the software is the brain.

teichman··on There’s scant evidence that healthy foods prevent cancer or fatty foods cause it
This newspaper article states "In 2007, a major follow-up [to the 1997 AICR report] all but reversed the findings." They don't cite the study or provide a link, but it's almost certainly the 2007 AICR report.

Fortunately you can take a look for yourself [0]. The published research findings are pretty much the opposite of the Star Tribune's claims that eating healthy has no effect on cancer.

These are the AICR recommendations:

    Be as lean as possible without becoming underweight.
    Be physically active for at least 30 minutes every day.
    Avoid sugary drinks. Limit consumption of energy-dense foods.
    Eat more of a variety of vegetables, fruits, whole grains and legumes such as beans.
    Limit consumption of red meats (such as beef, pork and lamb) and avoid processed meats.
    If consumed at all, limit alcoholic drinks to 2 for men and 1 for women a day.
    Limit consumption of salty foods and foods processed with salt (sodium).
    Don't use supplements to protect against cancer.

For remembering things: check out Anki, or any other spaced repetition system. Rote memorization isn't the complete solution, of course, but problem solving becomes vastly easier when the components of the solution are readily available in your mind.

For some reason our schooling systems haven't picked up on how incredibly useful the spacing effect is. Use it to your advantage! It has made a real difference for me.
