2. It repeats the same finding over and over (141 flops per byte, for example), without going deeper.

3. I stopped reading about a quarter of the way through because it felt like it was never going to stop teasing me about what it was going to tell me and actually tell me it.

4. It seems to assume the reader has a lot of context that isn't explicitly laid out (and which the reader wouldn't get just from reading the prior work, which is cited).

For example, I understand some of what it is saying because I used some similar techniques to benchmark things in the past (running at multiple scales to estimate overhead + marginal gains with a linear regression), but I wouldn't expect anyone who hasn't personally done that to follow the prose.

What, so that they can debug in Chrome and put the fusing and inertial navigation processes in isolated web views?

I wouldn't be so sure of that. But look at the bright side: By the time this administration's over, we'll all be billionaires!

I get the impression they want you to use other apps to access HomeKit (the Home app didn't even exist for the first one or two releases of iOS with HomeKit). Which feels very un-Apple, but whatever.

Of course, you probably want to arrive at your next charge stop with 5-10%, and the top 10% of the battery charges very slowly in all EVs, so you normally multiply by another 0.80 factor to take that into account.

I’m sure having access to your own SAT scores (or even remembering what they were) is highly predictive of not being someone who it would be illegal to fire because they are too old… which is probably the point… and why I’d expect most HR departments to shy away from this requirement.

* If 1/3 of calculus physics for engineers fail, they take it next semester.

* If 1/3 of gen-ed physics for poets fail, the professor better have a good explanation for the provost.

* If 1/3 of physics for pre-meds fail, the professor better have a pretty good home security system and might want to think about having the family stay in a hotel for a few weeks.

Regardless, as a civilian, you do have to pass a written multiple-choice test on flying theory before you can solo. Any time you spend in the cockpit before passing that test will be under the supervision of a Certified Flight Instructor (CFI), in a plane with dual controls, and you are not acting a pilot-in-command.

So, although the parent may be slightly over-focused on the USAF way, I think it is fair to say that for any type of pilot training in the USA, you do have to complete academic ground training (including passing a formal written test) before you are truly “given the controls”.

How would you calculate a crosswind component from the runway heading and reported wind speed and direction without trig? How would you think pilots measured their distance to non-directional beacons before GPS and DMEs existed?

How would you solve for fuel remaining without algebra? How would you estimate the best speed to fly with a given headwind to maximize fuel onboard at the intended destination without calculus?

A very basic principle of glider flying involves finding the tangent to a curve. Is calculus not applicable there?

Fuel consumption is often estimated by numerical integration of fuel flow rate. That doesn’t require an analytic solution of the integral, but I think most pilots have at least a passing familiarity with the concept.

> Furthermore it's categorically false that you need to pass ground school before you're allowed to fly.

I interpreted the parent’s statement to mean “before you fly solo.”

But more to the point: If you do poorly in your first semester and drop out, then it doesn’t really matter if the SAT would have done a good job of predicting your second semester performance.

The real issue is that standardized tests disenfranchise lower SES students less than any other metric.

Everyone who takes the SAT has to sit in the same room for the same amount of time answering the same questions. You can’t just pay someone else to take it for you (like essays) or select which difficulty level you take (like going to a prep school with grade inflation), or luck out in who your parents know (like recommendation letters).

Some may have better opportunities to learn the material, but, at the end of the day, you have to actually learn the material. There’s no getting around that.

As your own GRE anecdote shows: A little studying with some inexpensive books makes all the difference. Unless things have radically changed, a couple SAT or GRE test prep books are significantly less expensive than just one college textbook.

Bluntly, the reason SATs are better correlated to college performance than other measures are because of the reasons I mentioned. They strip away most of the privilege of coming from a high-SES family.

Yes, but that's a function of how fuel economy and capital impact the overall economics.

Cargo = (usually) one flight per night.

Passenger = (usually) many flights per day.

It's important for cargo airlines to have low capital costs for an asset that spends a lot of time not making money, but it's important for a passenger airline to have low operating costs for an asset that's burning fuel all the time.

Passenger airplanes are repurposed for cargo when newer, more fuel efficient airplanes come on the market.

What would work is to mill a knife edge into both the end plate and the can and use off-the-shelf copper Conflat ("CF") gaskets, which are available in a large number of standard sizes.

You'd have to work out a way to hold a vacuum in the can while you're tightening the flange though

A mile off Interstate-5 in the southern Central Valley, and you can’t tell you’re not in Texas oil country. Santa Barbara regularly has oil leaks from the offshore production in the Channel Islands area, and Beverly Hills High School famously has a productive oil well on campus.

So the state isn’t going to literally run out of oil (though lack of imports could lead to shortages).

This also neatly explains why Boomers were able to have a good life with just a high school diploma. Wikipedia has a good chart, but the short version is that having a high school diploma in 1965 meant you were better educated than 50% of the labor force.

PhDs are the new undergraduate degree.

You can't become a licensed electrician without doing x hours of apprenticeship under licensed electrician. And each licensed electrician doesn't need more than one or two helpers at a time, so...

Hollywood is the same. Want to join SAG? You need to get cast in 5 SAG productions. Oh, but SAG productions only cast SAG actors? Oh well...

Meanwhile, all us nerds were trying to teach anyone interested how to write software. Look where that got us.

The nice thing about ULAs is that you can have completely static addresses for internal services.
