If the learning experience is simplified to listening to a lecture, either live or recorded, and all grading is done algorithmically, then yes, there is no scaling limitation. This would be considered a very poor learning experience though. Even in the School of Engineering at Harvard, even for the CS classes, very few use autograding. Students expect individual feedback on their work. They expect the ability to personally interact with teaching staff. They expect group work, labs, office hours, reading groups, and some level of supervision over these activities.

I work at Harvard, and I can tell you there is a real push to create a quality experience in remote learning, and a lot of resources are being directed towards this. It is not just the same classes via Zoom. Of course these enhanced learning environments could be replicated on campus as well, there's nothing particularly special about the remote learning environment.

But as you suggest, it is the residential experience that most folks are paying for. Harvard considers the residential experience as one of their primary value propositions. That is why Harvard and other schools are working very hard to get students back to campus. It's a difficult balancing act between this and maintaining the health of the campus. A major outbreak amongst undergrads would be a serious blow to everybody involved, so health is always going to come first.

Also worth noting that 20% of Harvard students pay 0 tuition, and more than 50% get needs-based scholarships. https://college.harvard.edu/financial-aid. So if you're smart enough, and/or fit into the financial aid brackets, why not go to Harvard? What's the risk there?
Yeah, I'd be really upset. Angry and disgusted. Thanks for that perspective.
Yup. Another good examples are Nortel and BlackBerry. The government in Canada needs to be supportive about developing global leaders in expertise. Healthcare, once considered a world’s top, isn’t really today, but many Canadians still retain to the idea it is.

German here. I don't trust my government to not lie (based on past evidence). However, I don't think the government is competent enough to execute this particular type or lie (or even creative enough to come up with it in the first place).
Hah I live above my means and need a high salary _because_ I moved out into the countryside. Maybe it's different where you are, but living in the country is expensive. It won't look like it from the outside, but ...

My home insurance, my heating, my Internet, my electricity, all cost more than if I was urban. I own and maintain my own water supply and sewer system (septic). I have power lines coming up from the road, over a hedge of cedars that cost me $2000 to trim every few years or they'll impede the power lines. On my property, so mine to deal with.

I had to buy a little diesel tractor ($15,000), I had to buy a zero turn mower ($5000) because mowing 2.5acres (out of the 6 acres I have) would take forever otherwise. We need two cars because of where we are.

And property taxes are super high for me. They'd be cheaper if this was an active farm business making over $7000 CAD a year, but it's not. Because how could I do that while also working a full time job?

And yeah, the commute. Not fun. No gas costs really because I drive electric and plug in at work (and home), but still.

But I have chickens and an orchard and a woodworking shop, and make wine from my own vineyard, and have room in the garage for a Saab 900 SPG that I will restore...someday... and my kids have lots of yard to look out at while they sit inside instead and watch videos of people playing video games ...

I'm not sure about this. I'm not a fan of the ACT/SAT (I've never taken them and somehow wound up with a master's degree) - but what I worry about them is that it removes one somewhat objective measure that you could point to in scoring. When you remove that, well, what do you look at? I think that's where we see students who come from well-off families have an even larger advantage because they can be captain of the sports team, the debate team, volunteer at the hospital, etc. Whereas if you are poor and smart - you work a second job to support your family, or you spend as much time not at home as possible.

Good luck convincing an admissions officer that working a second job is more "valuable" in the process than doing all these other things when they want to maintain the "image" of the university.

Without an ACT/SAT you'll also probably get more applicants hoping to hit the lottery from an admissions officer too.

I will say that obviously wealthy parents can pay for a tutor for the ACT/SAT, but a poor kid can get a practice book for $20 and at least have a shot.
IANAL, but I imagine it's generally hard to charge someone for simply turning a blind eye to illegal behavior. But if you come to me and say: "Hey, I've figured out a way to embezzle $100K from the company and I'll give you a cut if you help me," if all the facts come out at some point, you can be sure I'll be fired at a minimum whether or not there are any criminal charges.
I’ve long thought gravity is more likely to be the product of space between masses, not something that alters it. My thinking is the “alteration” of we perceive as gravity is lopsided entropy due to a field with a gradient of space.

It is not so different. To double the electric charge of an electron you also have to double its mass.
I don’t mean it as an attack. I’m affected by the above too. Sometimes it’s because you look too far down the road as you allude to. But that could be part of an “excuse” mechanism.

Breaking things down into more discrete unconnected units allows addressing neater (less messy) problems/chores.

In myself I do notice over complicating things as an excuse to put them off and waste time. But as others suggest, sometimes you just have to power through and get things done.

And in most cases it’s not a hard or difficult work. The hard part is committing to doing it. Once you actually start it’s mostly a breeze.

I didn't grow up with gameboys but with the zx spectrum, I don't have a childhood attachment to Nintendo. Once in a while (3-5 years) I think it would be good to check what they offer, but usually there's a hoop i have to jump through and it also requires spending money on a new console in addition to my PS3/4 so...

> How do they write the right stuff?

The article claims that it is their process, and although they are certainly extremely thorough, I don't buy it. At the very least, they cannot be compared to most developers apples to apples.

Why?

> NASA and the Lockheed Martin group agree in the most minute detail about everything the new code is supposed to do — and they commit that understanding to paper, with the kind of specificity and precision usually found in blueprints. Nothing in the specs is changed without agreement and understanding from both sides.

For most anyone working as a developer, could you even imagine what this would be like? Specs not changing or only changing in very small ways that are documented to the nth degree not only is impossible from a practical standpoint for most fields of software development, but such a different process that it's essentially a completely different field of work.

> Most people choose to spend their money at the wrong end of the process

> In the modern software environment, 80% of the cost of the software is spent after the software is written the first time

I would argue that this is largely the result of:

1. Incompetency as far as specifications go (suits don't know what they want, or what they are asking for)

2. Large changes in the specification (moving target)
I can't tell if I'm just spinning my wheels at this point, but they're not trying to make themselves feel better, it's about fostering an environment for including those who do care. OpenZFS wants a more diverse user and developer community. Good for them.

And if you think that no professional developers ever break their APIs on a whim, you're either very young, or haven't been paying attention. Google does this all the time across their ecosystem. It's annoying, but you learn to get over it.

If you don't like it, fork it.
That would also be the perfect way to avoid disclosing the vulnerability so they could keep using it.

Not saying that’s what is happening here, but it’s not like Facebook has a glowing reputation to begin with. Telling the vendor that a future release will patch the bug gets everyone to stop asking questions without really knowing if it’s true.

Rust has Display: https://doc.rust-lang.org/std/fmt/trait.Display.html

On the doc of ToString you can find the following note:

>This trait is automatically implemented for any type which implements the Display trait. As such, ToString shouldn't be implemented directly: Display should be implemented instead, and you get the ToString implementation for free.

I think ToString exists mostly in order to have a more convenient API to get a String out of a display-able type, otherwise if you used Display directly you'd have to use a variant of that boilerplate every time: https://doc.rust-lang.org/src/alloc/string.rs.html#2185-2192

Because that's downright wrong, and it has been a longtime complaint of mine since childhood, which my family will be happy to attest to the degree of ear bending that results from these types of shenanigans every single time I discover them. Further, if you think that idea is niche, I'd like to point you toward the right-to-repair movement,as well as the bloody Android ecosystem as well.

The only people to whom what you refer to as a "niche" idea, are a niche into an nd of themselves; namely production companies that wish to infringe on the right of First Sale.

Get with the 21st Century. People are not satisfied with planned obsolescence, and while they'll consume things made in a user hostile way, I'll assure you, once an actor that commits to consumer friendly electronics fabrication gets traction in the space, and shows signs of the ability to collect good talent, people will flock to them.

Gravity waves definitely exist, and have photon-like properties, but I believe the problem is designing an experiment which would prove that gravity is quantised and therefore carried by particles.

My father was in the RCAF and was in the running to fly the Arrow if it was built (he did see prototypes).

This number assumes UAE's population of 9~10 million and includes (I think) the immigrant population.

I am not sure what you consider "not very worrying", as I don't think that the 5 million Indians and Pakistanis living in the UAE are responsible for much of the carbon footprint of the country. So for the Emiratis and Western expats, we should consider their per capita footprint to be at least double the average.

True, but only if you stick to electrons. Switch to muons, and you have more mass, but the same electric charge. Depending on what particles you use, the mass and charge vary independently.
Glucocorticoids are very old drugs. If there were a new patent at this stage in the US, it would be a combination drug or delayed release oral form ([source](https://www.patentdocs.org/2018/09/patenting-repurposed-drug...). There's also a dozen alternative generic analogues. There's already a [markup](https://www.washingtonpost.com/news/wonk/wp/2018/06/19/the-g...) for very common drugs in IV form, which is bad, but unfortunately it's a very small part of the ICU bill to begin with in the US.
You still didn't tell me who these "experts" are, though it seemed you were referencing several in a prior comment, so I'm unsure how to address that point. I'd of course respect the opinion of an expert, and I'd recognize that I have a very good chance of being wrong, but that makes it even more important to question things. If I'm right, we come to a better conclusion; if I'm wrong, I learn something.
So there are cases in which you could consider energy being "stored" somewhere. The canonical example from EM is energy being stored in the EM field itself like in radiation. In this case for classical static gravitation fields, the potential energy has more to due the motion of the orbiting mass and the nature of the force itself being conservative and so it isn't really stored somewhere in that sense. What I mean by that is a mass that moves against that gravitation force will lose motion due to that force (specifically motion with a component away from the planet) and from math you can then calculate that kinetic energy that would be lost from the orbiting body if it were to get a certain distance away from the mass for example. This process is reversible, that is you can trade distance for kinetic energy, which is a familiar situation like that of a ball being thrown straight up in the air, slowing and then stopping at some height, then falling back down. The reversibility of this trade off then allows you to associate an energy, potential energy, with given heights off the ground which makes calculations easier by considering it as a trade off between the motion and these greater distances. This however isn't the case for all forces. For air resistance this isn't the case, so you can't associate air resistance with a potential energy as a counterexample.

There are however cases in which energy is real in a sense and isn't just a convenience, and for the most part this is when that energy is associated with motion (momentum specifically) of something. Also, that something would be localized and thus could be considered being stored somewhere. For some examples, of course kinetic energy, but for EM energy, you could consider it being the momentum carried by photons after QED.

When you have an array, it's way faster to check the existence of array[key], which is O(1), than to loop over the full array to find if one of the values match the one you're searching for, which is O(n).

This is used in hash tables, for example: https://en.wikipedia.org/wiki/Hash_table

Object properties in JS are mostly the same thing.

I guess other extensions can't do the same because they don't have a simple value to search in a whitelist, but rather a list of regex which must all be executed.

3-5 months after graduating university, I thought academic titles would mean something. Today I know better. I think this is a real good development. While I cannot complain about the quality of my former teachers, logistics of knowledge are cheaper than ever before. Everyone could at least listen to the best experts in their respective fields. Subjugating students with debts like that isn't common where I live and it looks "decently perverse" from outside the US.

I think it was always a brand but the educational value is questionable in modern times. What they sell today is mostly access and nepotism. I think a real benefit is the tendency to leave your family home for higher education. Maybe that is why I remember my time studying so fondly.
