I have the opposite experience. Goes to show the difference between people.

I've always had trouble internalizing the "physics" of physics or chemistry, as if it were all super arbitrary and there was no order to it.

Computation and maths on the other hand just click with me. Philosophy as well btw.

I guess I deal better with handling completely abstract information and processes and when they clash with the real world I have a harder time reconciling.


Chemistry in particular is just taught very poorly in USA middle/high school. If anything, it perfectly hinders building that internal understanding.

"Chemical bonds fill the electron shells, which is why we have CO2. But don't worry about why carbon monoxide exists."

"Here's a formula to figure out the angle between atoms in a molecule. But it doesn't apply to H2O, because handwavy reasons. Just memorize this number instead."

Students don't gain an understanding of the subject, because the curriculum doesn't even try to teach it.


This was kind of infuriating about high school chemistry. We were taught so much simply is and that's that. Gold and Mercury differ by one proton, so why is one a dense, yellowish metal and the other one liquid at room temperature? Carbon and Nitrogen sit right next to each other on the periodic table, so why are their chemical properties so different? Why are there so few elements that are ferromagnetic? We dove relatively deep into chemical bonds and isotopes, but glossed over fundamental things like why compounds with similar structures had seemingly random, unrelated properties.


But if the alternative becomes more real estate investment than we already have won't that be even worse?

Investing in the stock market at least in principle is investing in businesses that use that money to increase productivity. We should discourage investment in vehicles that do not optimize for productivity (real estate, bitcoin, metals and similar).


Selling your investment to pay taxes for unrealized gains forces more liquidity and movement in the market and might have a huge impact on preventing bubbles forming.


How does that work when some of the most outstanding ways remaining to make money are from a bubble?


I am not sure if you're agreeing with me or not lol


Likely a lot of medium posts? That's my theory anyway.


And then you get to the reason why everyone complains childcare is expensive.


What if you get a much better service from Uber?

Most local produce initatives fail because they're not actually better than the global/international variants, especially considered from a price/quality pov.


OOP is for problems that require complex modeling, indeed if you require just complex calculation it is useless.


For sure. Cost for example?

Just pointing out the obvious steelman people seem to be missing.


You can go on sidequests but first you need to accumulate sufficient credibility.


This is it, pretty much. If you do your own thing and it works, then you'll come out well. If you do your own thing and it fails, you'll look bad, while if you do what yiu're asked you're going to be much safer. So if you go off-piste you should have some confidence it'll work.


> if you go off-piste you should have some confidence it’ll work

Just remember that the definition of “working” is in the eyes of your manager. Assuming they’re competent and not pointy haired boss, then they might have different goals and priorities to you. I’d you end up diverging from them, even if what you did is technically good and a good fit for the project, you’ll probably have a bad time.


Yes, you do still need to solve a problem that is considered a problem and at least around the same level of importance of whatever you were supposed to be working on, preferably greater.


You can configure opcache to never stat unless it's reloaded


Huh, well that sounds like it would have been useful. It's been at least 10 years since I did any php dev work, but maybe I'll find an excuse to use it again for something.


Not only can you configure it to never stat; it has also been on by default since PHP 5.5 afaicr


Funnily enough PHP solved this perfectly with composer, but unfortunately it's not an enterprise-level programming language /s
