For anyone else interested in Bloom's 2-sigma, here's the original paper (1984): https://web.mit.edu/5.95/readings/bloom-two-sigma.pdf

Blows my mind that 1:1 tutoring dwarfs the impact of other factors such as socioeconomic status, reinforcement, assigned homework, classroom morale, etc (at least according to the researchers).

Does anyone know if this thesis has been replicated? Or if these results hold in modern times (original study was 40 years ago)?

The article states that Anaina and Burke separately conducted their tests, but social robots [1] have been shown to be effective in individual tutoring. Human tutoring is not always better than a well-designed computer program [2]. There have been issues with how studies interpret their effect on group size / scalability [3].

Wow, I read your informative link. Where are these jobs? I went through a round of interviews last year for Sr. positions, across a number of locations in the U.S., and quite frankly, the average salary for the positions interviewed for was $80k less than most of those in the list, and $230k less than the SWE manager in the list.

The page lists the locations, and the businesses, where these jobs are placed. Unless you live on the coast (or end up in Denver/Austin), you're going to have a harder time reaching these salary numbers.

The writing style has me in stiches, it feels at odds with the layout and imagery, but completely fits the character of the story in question.

I wonder how well a Real Housewives-style show would work set in the Sengoku-era.

I think the author assumes u know how to apply a practical foundation. We need another book here.

I applaud the author for putting thought into how to design digital controls, in contrast to the "just put whatever garbage on a touch screen" strategy most carmakers do today.

However, I still question the benefit of this complex, modal control (you have to press a single knob to "cycle between" multiple modes). My ancient, 2016 car features three knobs. This luxury allows me to, without looking, adjust any of three settings (temp, fan, air location), as well as a button which does each seat heater, without any "check what mode it's in, tap, look at the tiny screen, tap again if necessary" step.

True, in this trim, my car does not have a thermostat mode, which in theory is useful, but it is so trivial to modulate the temperature based on "do I feel cold, hot or comfortable right now" and reaching over to twist one of the controls anyway, and even in the other car I have which has this mode, I frequently need to adjust things anyway, except in that car some of the functions require multiple mode changes on the touch screen and looking away from the road.

The author is pretty clear that having more than two modes diminishes the usefulness of the interface. Three modes was complex enough that he redesigned it down.

I've changed the channel tuner when I've reached for the volume knob. If the haptic feedback between the two is clearly different, that will help, no?
