An argument presented in this case is that increased pay to college athletes will incentivize them to spend more time on their athletics and less on their academics. How convincing do you find that argument, applied to athletes in a) Top Tier D1 Football programs, b) D1 programs but for less hyper-commercialized sports (say track, or volleyball), and c) D2 or D3 athletes with little-to-no aspirations of a future in professional athletics

I had the exact same reaction to it. Some enormous fraction of all non-fiction is an essay-length idea stretched out into a book length. It's disrespectful to the reader, but it's what they need to do to make a sale. No one wants to buy a pamphlet

Safety is a big concern, and a place to safely store your bike (at home and at work) is another big one. I'd imagine lots of the walkers live in condos or apartments where storing a bike can be really tough.

I used these lectures as a method for learning algorithms as a phys/mech eng with no CS background. I found them incredibly challenging but the lectures were written exceptionally well. On an internet with thousands of resources on this material, this was the very best I found.

Agreed, but jeans are really unattractive at the distances the author is riding. His circumstances are unfortunate, since the set of advice applicable to <5 mile rides is very different to his ~20mile trip.

Related, I'm very impressed by his speed. I ride about 9 miles to and from work and it takes me ~35-40 minutes door to door.

Justice Thomas also broke a multi-year streak of silence to make fun of his alma mater, Yale. Playing the long game.

How do state broadcasters fit into this theory? The CBC and BBC produce content in a similar style to the for-profit broadcasters (better, but definitely similar in more ways than its not), but without the advertising mission.

This is a very dismissive comment. Many of my peers in grad school were developing finite element techniques - it's a huge area of active ongoing research. Getting realistic results is very tough in an application with non-linear materials (probably looking at anisotropic composites) and possibly fractures like this.

I recently read and enjoyed the essay version. Would you recommend the book? Specifically, did you feel that the amount of depth in the book necessitated that format as opposed to an essay?

I'm frequently disappointed by really good ideas that could be presented in a dozen pages being stretched to occupy 200 (e.g. Deep Work)

"makes me think that they are running the stepper motors in a closed-loop mode similar to how you'd use a servo. I am not 100% on that, "

Do the steppers have encoders on them? If not, the machine can't do closed loop control. It can keep track of where the rotor should be based on counting the steps of coils it has energized, but it has no way of directly keeping track of the rotor. A large enough torque resisting the rotor's rotation can cause the rotor to skip steps, but this doesn't influence the energizing of coils in the stator so the machine has no idea that anything has gone wrong.

An encoder lets you directly measure what's going on with the rotor (and therefore the shaft of the motor). You basically keep track of where you should be (based on counting the steps delivered to the stator coils) then use the encoder to validate. e.g. 'I've sent 12 steps so I should be 48 degrees from where I started. My encoder is reading 26 degrees, so I must have skipped steps somewhere along the way.'

I think you mean to refer to another track from that album, "The Irony of It All"

Your point absolutely has merit. I know some, but not many, badly overweight people who exercise regularly. I know some, but not many, skinny people who never lift a finger.

I was mostly trying to address the direct cause-and-effect conclusion the parent comment was making with breathing hard == losing weight
