Fosdem 2026> By far, the biggest hurdle was distribution of the monitoring nodes. FOSDEM staff did not allow us to place nodes without someone (such as devroom managers) watching over them at all times, otherwise we would’ve liked to place them Friday evening before the conference started.
what a bizarre stipulation

In the early days of personal computing CPU bugs were so rare as to be newsworthy.
Senza categoria@gabrielesvelto I actually keep meaning to find a decent reference text on FET construction and modelling. I've got plenty on SI/EMI, power delivery, etc. but everything I've found for FETs has been the sort of thing that presumes you're either someone with a deep background in semiconductor physics or a professional semiconductor/ASIC engineer just looking for a reference text. very little out there for EE folks who are coming at it from the practical side.

Senza categoria@gabrielesvelto (what you said is absolutely correct regarding "signals" in the HDL sense of the word, it just gets a bit muddled when we're simultaneously talking about the analogue behaviours of the actual electrical signals, hence the clarification ^^)

Senza categoria@gabrielesvelto nitpick: the propagation velocity of a *signal* in a circuit is not affected by the voltage magnitude; that is a function of the (innate) dielectric constant of the material.
however, a higher core voltage does mean that a rising edge tends to reach the gate threshold voltage of a transistor more quickly, which reduces the time it takes for each asynchronous logic element's output to reach a well-defined state after a change in input, thus propagating logic *state* more quickly.
