Q: Given a Diagram, Find X

Find X I was inspired by math questions in which one is asked to "Find X" for a given shape. Originally, I was just going to have the challenge be to print the x and y location of the character 'x' in a String. But I supposed that would be too simple. So I considered the context they were normal...

@arda Help, how do I install a monarchy in Turkey? It's not on apt-get.

chat.stackexchange.com/search?q=me+name&user=&room=240

@Oliver I'm not sure why you keep saying this

@noɥʇʎPʎzɐɹC run sudo apt-get install erdogan and it should be installed soon. It's a PITA to remove though.

It removes some packages like openvpn and tor, so keep that in mind.

@arda I don't have superuser permission. I heard of this rootkit called "GNU/coup". Can you help me with that too? It's also not on apt-get.

I'd love to keep talking but its 3:37am and I have to wake at 6:30am, and I have chem exam tomorrow, which I didn't study much for.

question: how to make weak propert yon object in JS?

@El'endiaStarman I was reading feynman lectures and I saw " a sphere is the locus of all points for which the distances from two points are in a constant ratio." and I thought of the gravity voronoi maps you were doing because that was our final result for the equiforce surfaces with two bodies

what happened to that?

@LuisMendo It's hard for me to put a figure on what exactly I'm interested in (mainly because it doesn't really follow a pattern).

When it comes to statistics, I think I typically like "simple" situations (coin flipping, Good-Turing frequency estimation, etc.). On the subject of geometry, I've read about arborally-satisfied point sets and tropical geometry and a bunch of miscellaneous other things.

What's the correct term for scaling up an image by an integer amount? Upsampling? Upscaling?

Upscaling, although that refers to increasing the size by any amount, not just integers

or, upsampling also works I suppose. Upsampling means "increasing the number of sample points" which applies if you're increasing the size measured in pixels.

Image scaling

In computer graphics and digital imaging, scaling refers to the resizing of a digital image. In video technology, the magnification of digital material is known as upscaling or resolution enhancement. When scaling a vector graphic image, the graphic primitives which make up the image can be scaled using geometric transformations, without any loss of image quality. When scaling a raster graphics image, a new image with a higher or lower number of pixels must be generated. In the case of decreasing the pixel number (scaling down) this usually results in a visible quality loss. From the standpoint...

They all come from Old Norse

Though nowadays they are different

Question: why do people stand up as soon as plane lands?

@betseg To leave the plane

This process would go much quicker if each seat had an eject button

@KritixiLithos but they have to wait at least 5 minutes until they can exit.

@betseg But at least you can get your bag from the overhead compartments while waiting

What if plane starts moving/stops quickly? They would fall down.

11:27 AM

People get up after the seatbelt signs are off. Then it would be safe for them

What if plane won't use a bridge, and stop in the middle of nowhere? The bus will wait everyone.

@KritixiLithos you are too optimistic :)

This is a pointless discussion

We all have our opinions, I usually get up as soon as the seatbelt signs are off

A plane can't reverse on it's own. Even if it could, it can't get up to speed so quickly that you would fall. The seatbelt signs usually go off if the parking position is reached, where the plane is immediately locked in place on the tarmac, so there is nowhere for it to go.

Some people actually stand up while taxiing.

11:42 AM

That's fine, too. If there is a problem, the flight attendants will ask you to sit down.

After a long flight it's nice to stretch your legs whether you can get off the plane or not

That's not a bad thing.

It usually decreases DNS lookup times significantly (because they are cached longer).

Maybe, but secretly re-routing a request to go somewhere other than its intended destination is not ok

Anonymous

I have a lot more faith in Google's DNS than my ISP

You request will still be resolved by Google if you set it. It's usually just cached by the proxy. It's the same as any reverse proxy CDN. If you connect to SE, you are connecting to Cloudflare, and not SE's servers. This is a common practice for almost all Internet protocols.

It also prevents catastrophic DNS outages, because a failure takes longer to propagate.
