I have a different perspective. The worst types of cancer kill slowly and cause agonizing suffering.
Alzheimer's leads to negative outcomes for your caregivers, but by many accounts many affected individuals do not suffer all that much, if at all, due to their lack of awareness.
Right? And not even a way to get a transcript, that I can see. Who has an hour to listen to some dudes talk about a question that could and has been answered in a few seconds?
The one and only time I ever got a machine infected with malware in my 30+ years of using the internet was when I fell for Forbes.com's request to please disable my adblocker. I promptly got hit by a trojan carried in one of their unvetted ads. Browsing without an adblocker is a critical security issue, and I will drop Firefox without a second thought if they ever cripple blockers like Google did.
> I'm pretty sure AI is going to lead us to a deskilling crash.
That's my thought too. It's going to be a triple whammy
1. Most developers (Junior and Senior) will be drawn in by the temptation of "let the AI do the work", leading to less experience in the workforce in the long term.
2. Students will be tempted to use AI to do their homework, resulting in new grads who don't know anything. I have observed this happen first hand.
3. AI-generated (slop) code will start to pollute Github and other sources used for future LLM training, resulting in a quality collapse.
I'm hoping that we can avoid the collapse somehow, but I don't see a way to stop it.
I am not sure why the author specifically mentions a $7 cable when the Raspberry Pi and accessories are going to set you back close to $100. That is by far the most expensive component. The money is possibly better spent buying a programmable remote.
After a recent update, my keyboard started typing "and" as "and's". This happens 100% consistently, but only when swiping. I don't understand how such a bug happens. Yes, 's' is next to 'd', but "and's" is not even a word.
Working with 3rd party keyboards is still the same nightmare it was when the feature was introduced many years ago. For one, iOS will randomly switch you to a different keyboard. Or the keyboard will just crash.
I do not see any 'radical difference' in the numbers. Individuals who choose not to get vaccinated are likely to be less informed and more reckless in other aspects of managing their health and their lives in general, so the relatively small difference between the populations is perfectly understandable.
That's so weird. What do they teach in American schools? Apparently not even basic geography? The fact that Indonesia was Muslim is something I learned very early on - certainly before high school.
> What do they teach in American schools? Apparently not even basic geography?
This doesn’t fall under the category of basic geography. I can guarantee you that the majority of people you attended school with would not be able to locate Indonesia on a map, much less tell you about the religions practiced there.
TBH, without going into overmuch detail, I wouldn't generalize from my educational experience to the American educational system as a whole. I think it was better in a lot of ways, and worse in a few ways, than what most people would have received, and I wouldn't be surprised if there were some particular holes in my knowledge due to taking part in multiple curricula from different institutions.
>The problem does not state that the numbers have to be integers. a and b happen to be 9 +- 2 sqrt(11)
but the problem does state that you should be able to do it in your head. who exactly should be able to formulate and reduce simultaneous equations in xy then apply the quadratic formula (with some spicy +/- to keep track of) to get an answer with an irrational number, all in their head? usually, when a problem like this is given there is a shortcut that leads to a simple, not only rational but integer, answer.
the statement "you can do it in your head" generally does not entail this much complexity, as the person who said "you can do it in your head" comes out and says after previously spending a fair amount of time working on it.
words matter, people, that's why I didn't throw in the adjective integral even though I could have.
Well, I had to write it down, but I have to write down everything these days. But from the way the problem was phrased, it was obvious you don;t have to actually find to numbers.
None of this is required for solving the problem in your head. All that is required is the ability to add 1-digit unit fractions in your head, as the problem requests.
> the statement "you can do it in your head" generally does not entail this much complexity
It's funny that you jump to accusing OP of falsely claiming you can do it in your head, without apparently considering the alternative: that the intended solution is a simpler one than you outlined.
Trust me, you can do this in your head if you know basic high school level math, and you don't need to solve quadratic equations or keep a ton of numbers in your head at the same time.
If I ask you if 123456789 is a prime number, do you complain that it's not fair to make you perform division on such a long number?
The difference between the two is that it’s clear that 123456789 can’t be prime since the sum of the digits is a multiple of 3, which doesn’t even require finding the sum since we know 1+8, 2+7 up to 4+5 are multiples of 3. I can even tell you that 43717421 isn’t prime without having to do a divisibility test on it by looking at the digits, although it is a bit more tedious than the 123456789 field.
the difference between the two is that I removed the factors of 3 from 123456789 to get 13717421. so much for your secret knowledge of a hyperspecific case.
You're still missing the point of these problems, which is to challenge you to come up with a clever proof rather than brute-force the solution.
dhosek understood the assignment by making an argument that 123456789 is composite without relying on explicit division of a 9-digit number, which most people would find rather difficult to do in their heads.
Similarly, the posted link is about tiling a mutilated chessboard with dominos. Tiling problems in general are NP-hard, so clearly this isn't something you can solve in your head _in general_, but the charm of that specific problem is that you _can_ solve it by making an insightful observation to avoid the brute force computations.
Similarly, for the puzzle you complained about: we are asked to find 1/a + 1/b where a × b = 37 and a + b = 18. The general solution is to solve a system of two linear equations which involves solving a quadratic equation, which is possible, but tedious and difficult to keep in your head, but the entire point of the question is that there is a better way to figure out the result.
