Why do you need to send the samples over USB?

The accessibility checker in Chrome/Firefox devtools would immediately flag this.

This feature could be potentially be activated whenever the page is hidden (eg. by pressing the home button), although it would be very annoying for regular users.

I read a paper a while ago (which I have failed to locate) which used around binary masks, each in front of a single photodiode, as input to a neural network, which estimated the number of people in front of this effectively ~9-pixel "camera". The binary masks and NN weights were trained at the same time. Presumably, something like this could be used to detect lack of driver focus in a far less invasive manner.

I feel like this challenge would be a lot more interesting if the size of complete code needed to output the map were counted.

Additionally, while I don't know much about APFS, I don't think it would be beneficial to point the extracted app to blocks that are also part of the dmg file, i.e. some copying has to happen anyway.

Many consumer routers allow any connected device to configure port forwarding using UPnP. If you want, you can play around with this using a client such as miniupnpc's example client.

I wonder why they went with USB-C for expansion slots instead of PCIe

Yes, they are using evaporative cooling.

Ah, I was referring to the zoom-level-dependent clustering, which I find makes it hard to see the distribution of points when zoomed out all the way. There's still quite a bit of detail even with many of the points sharing the same location.

Why do news outlets so often use the phrase "high rate of speed"? Speed isn't a discrete event, it can't really have a rate, unless it is a rate of change, in which case they would be referring to acceleration.

This is fun and looks amazing, however there seems to be quite a bit of texture in the out of focus blur. There's also a lot of aliasing on the grass. Also, I think the camera shake could do with a very slight delay after the axe hits, and maybe a slightly slower decay curve.

This is very cool, but unfortunately it's hard to get a sense of what the actual spatial distribution of people looks like when nearby nodes are grouped into larger dots that obscure the local structure.

Would be interesting if sites could be grouped based on what services they rely on, or just grouped based on which have correlated downtime.
