For me, vim means muscle memory. I can say that it has become part of me!

SIM card provides hardware-based, simple and secure authentication of subscribers to mobile network operators. Until manufacturers start to embed standardized secure element on all phones, alternative software based solutions (password, etc.) are more complicated and insecure.

You can use laser printer toners to get same effect! They are magnetic as well and might be easier to get.

It's also easy to get better contrast - apply transparent tape to magnetic strip, remove the tape and put it on top of white paper. You can clearly see strips.

What about beamforming? Wouldn't signal strength depend on locations of connected wifi clients?

I don't know details of this case but it's very unlikely GS was violating any FOSS license for just modifying code (assuming internal use only).

The closest environment I got to work with Matrix-like UI but real experience was:

There is board I'm developing on with serial port, and kernel debug prints so much garbage it literally fills the entire screen in less than couple of seconds. It was because of faulty/broken hardware and there is busy loop that keeps retrying to access the device.

I could enter shell commands but I/O lines get mixed in between the verbose kernel debug lines. After some time my eyes synced to the screen scroll rate and I could follow the output from bottom to top to read it (repeatedly run command until I could catch the output correctly).

For the moment, I saw "blonde" in fast scrolling random code :) Anyone else had to work like this?

Not really, depends on definition of "close", i.e. how you measure distance. If closeness means distance in search space, then you're right, but it also could mean local vs global are close in value being optimized, but they are located far from each other in search space.
