At my previous job, I trolled a bad actor until they were so frazzled they mistakenly tried to hijack network resources from the us air force, resulting in immediate response.

How 3ve’s BGP hijackers eluded the Internet—and made $29M

3ve used addresses of unsuspecting owners—like the US Air Force.

Driver’s Output Impedance From IBIS

In a recent post from the SI-list I subscribe to asks a question; “How do you find the driver impedance information from the IBIS file?” Most of the time we want this information so that we can exp…

just been reading about DFE channel equalisation after watching Robert Feranec's latest video. it's a surprisingly simple and elegant approach, I don't know why I was so daunted by reading about channel equalisation techniques before.

not to be confused with the Darude model of conduction, in which the electrons play the notes to Sandstorm as they bounce off atoms in the lattice
