OK, I’ve read the wiki entry but I still don’t understand what KVM is, or why it’s needed. The last time I visited a data center - every server rack came with a laptop-esque looking control unit. What problem does KVM comes to solve? What does this invention improve upon a traditional KVM?

One could make the case that we can transform an k size array to a k-vertex-connected graph

Because traversing from one element to any other element is an O(1) operation using index arithmetics.

Same for n dimensional matrices.

Ohhh a stack that is 4 callback deep, are you running java on a potato?

Got optic to SFP bridge from my ISP (only because I insisted on using my own router) , that was fed into SFP to RJ45 adapter that I have bought (via Amazon - apparantly the ISP’s have lobbied to not import it here) and then connected my router.
That went somehow ok untill I switched ISPs , now the optic cable is fed into an ISP provided decryption module , paired specifically to the mac address of my router.

It’s like the ISPs went onboard with upgrading to optic because they could excert more control over their customers.

Assuming a stable URL

ffmpeg -i "(stream url)" -t (length of recording in hh:mm:ss format ) -c copy "recording.m4a"

And you could time it weekly using cron jobs

Serious question - as a normie I’m usesd to - Email Provider=Domain.
Google = @gmail.
ProtonMail = @protonmail

How does custom domains play into this? Does using a custom domain for mail requires a special entry in the DNS record?

Magnets, how do they work?
