Can someone sanity check me on this that the function is O(n^2)
static void f(int n) {
for(int i = 1; i <= n; i++) {
for(int j = 1; j <= i; j++)
System.out.print("*");
System.out.print("\n");
}
}

I'm not going to give you the answer, but you should plug in a number for n. Then count the number of times the for loops will be called. If the result is n^2, then it's O(n^2).
>>
>>62041857
Just code it and see what happens
>>
>>62041857
Yes. The inside loop will first run once, then twice, then thrice, etc. So the * gets printed
1 + 2 + 3 + ... + n
times. This formula is for the "nth Triangular Number" and it has a general formula of
1 + 2 + 3 + ... + n == n*(n+1)/2
Expanding the right hand side out gives (n^2)/2 + n/2 + 1/2, which is indeed O(n^2)

Is there any way to get LTE on a laptop without it being builtin? Something like a PCI/USB device that you plug a SIM card into and it provides internet. Is there any reason this couldn't be a thing? If not why isn't it?

it does exist and you could find them on ebay & amazon.

you just need a laptop with an empty mPCIe slot and a LTE capable WWAN card, I'm not sure what you would do about the SIM card if the laptop does not have a built-in SIM slot

I remember being excited about multi desktops for Windows, but then ended up never actually using it. I feel it encourages you to keep unused processes open in the background even worse than minimizing applications does. Yes, I have the ram to support it, but I still like to keep my amount of open applications down to 10 max.

Does anyone legit use Multi desktops/workspaces daily, and what for?

I do but I use i3 Manjaro not W10

Nah. Gimmick.

Didn't use it for the years I exclusively used Linux. Don't use it on w10 either.

Loonix autists cried when Microsoft implemented it and screamed about how it's not a new feature. What they didn't mention was that it is useless.

I found an old imac. I've always wanted to mess around in ios9 which is almost impossible on modern hardware (even though I heard its shit). What is something fun to do to it?

Its not going in the trash either.

Most programmers and engineers from the old days are bald and wear glasses with lenses about a 1/4" thick. The radiation did have some effect over the course of 20+ years surrounded by mountains of CRTs and computers all running at once.

Why don't companies care about privacy anymore? Last company I heard that implemented a real privacy measure for users was fucking Whatsapp, and that's just for messages themselves (they still collect when you message someone, for how long, et cetera).

I literally don't care if they collect aggregate statistics, but this is ridiculous. I don't want companies to build a profile on my personal habits.

Uh because they only care about profit, and selling personal information is one of the most popular business models currently. If you don't want them to build a profile, stop using "Free" services like Google, 4chan, reddit, facebook, etc.

If a service is "free" yet the company offering it is making money, ask yourself where that money is coming from.
>>
>>62041237
Because people trade privacy for convenience, and companies take that privacy and make profit from it (which is to be expected, barely anyone makes a product/service thinking they won't make money out of it).
>>
If people would pay for services instead of expecting everything for free there would be no need for the current model.

Is there a way I can completely disable network internet access in Windows? So when I dual boot into Windows it doesn't use ethernet at all, even with the ethernet cable still plugged in?

Would disabling the network stack be an option?
Maybe disable the ethernet adapter, but does that carry over each boot, permanently?

you need to completely remove your network drivers, the easiest way to do this is delete the sys 32 folder in your c drive, then reinstall any necessary drivers from a USB (video/mouse/keyboard), otherwise windows will reinstall network drivers automatically

not from within the OS.
require a key to access the internet through your router and keep the place the key is stored on your other partition encrypted so that the windows partition has no way to access it
