Comment Describes mediocre and bad engineers well (Score 2) 143

A lot of not very good engineers like these absolute answers and like things to be black or white. I run into them frequently. The worst is probably the IT security field, where things are often viewed as secure or not, with nothing in between. That is an epic fail in the real world, of course.

Good engineers are not like that at all, they understand things like risk management, redundancy, real-world aspects, human factors and cost. But they are a minority, unfortunately.

Comment The CA secret cert is also present (Score 2) 88

According to, just marked "non-exportable" (sorry, no English link):

Person that reported this initially:

Apparently being non-exportable is no protection whatsoever, and people are already offering the CA cert for download, which then lets everybody sign for this CA.

It is hard to display more fundamental incompetence with regards to certificate handling.

Interconnect gets smaller if you reduce speed as well when you reduce size. If you keep speed constant, interconnect stays the same size and it will consume the same amount of power. Well, roughly. The problem is that at these speeds you are dealing with RF laws, not ordinary electric ones and RF laws are pretty bizarre.

Chips basically have components (transistors, diodes, capacitors, resistors, and recently inductors) and interconnect ('wires').

Interconnect has been the primary speed-limiter for about 20 years. At 5GHz or so, it starts to become exceptionally difficult to get signals from one component to the next, and in particular distributing clocks becomes a limiting issue as clocks need long wires in order to reach everything. Making transistors smaller helps a bit because the wires get shorter and signal-strength (voltage) can be reduced. But that effect is limited and seems to have mostly reached its end.

The overall effect is that extreme over-clocking for the 15 year old Pentium 4 could reach 8GHz, but current chips do not do much better with both AMD and Intel going up to about 9...10GHz as absolute maximum.
