A quadratic function is just one possible polynomial. They're also not really related to big-O complexity, where you mostly just care about what the highest exponent is: O(n^2) vs O(n^3).

For most short programs it's fairly easy to determine the complexity. Just count how many nested loops you have. If there's no loops, it's probably O(1) unless you're calling other functions that hide the complexity.

If there's one loop that runs N times, it's O(n), and if you have a nested loop, it's likely O(n^2).

You throw out any constant-time portion, so your function's actual runtime might be the polynomial: 5n^3 + 2n^2 + 6n + 20. But the big-O notation would simply be O(n^3) in that case.

I'm simplifying a little, but that's the overview. I think a lot of people just memorize that certain algorithms have a certain complexity, like binary search being O(log n) for example.

We're talking about legally, not practically. Obviously copying movies is physically possible.

Dang, I can't even be mad with a face like that.

That doesn't seem worth it when you can fit that amount of storage in about 20 L with lithium ion cells (think a small PC case), or something like 40 L if you used sodium ion cells, which are looking like a new alternative.

Concrete offgassing of CO2 is already a big contributor to greenhouse gasses, so I can't imagine this battery version is improving things there. You'd probably have to wire your whole basement with electrodes to even access the stored energy.

It's sad that the best most startups can hope for is to be bought by a giant corporation. Not a lot of people are interested in just having a successful long-term business.

It's sad probably 90% of this stuff won't make it back to it's original owner. Who's still got serial numbers or receipts for something they bought in 2014? Most people will have moved on or had insurance replacements already

I'm not a professional, but all my powertools are covered under my renter's/hone insurance. It's incredibly cheap compared to car or health insurance.

Edit: I guess this doesn't count if the tools are stored in a vehicle parked anywhere but in my garage. There's definitely some policies available that will cover the full contents of your vehicle though.

This is the true "We did it Reddit" moment.

Just useful enough to become incredibly dangerous to anyone who doesn't know what they're doing. Isn't it great?

I've had the audio desync in cutscenes after leaving a game open in sleep for a week or two. I think it's an issue with how the game timers work. If they're counting since the game started, any slightly inaccuracy will become more obvious as the game is left open, regardless of sleep.

It's a little like comparing a top of the line gaming laptop to a middle of the road efficient laptop. Sure the games will run a bit better on the powerful laptop, but you're trading that for battery life. The Steam Deck is insanely efficient, and they made a few hard tradeoffs like the 1280x800 display resolution (which is great for battery, and honestly plenty sharp for the screen size).

I'm still a little blown away it runs Balder's Gate 3 and Cyberlunk 2077 at all.

You can't use cash online tho
