Engineers drift away from physics


As a retired engineer and all-round gadfly, I have lost my faith in structural engineers.  They build buildings that tilt in earthquakes, and bridges that collapse in mild winds. 

I blame this on a drift from physics, just like all the other sciences.  Everybody thinks they know what's going on, and make a stand on fossbook.  Then they can never retreat.  They test the dynamics on a shake table, but that isn't real physics.  They need more on-line monitors to see what the structures are doing, and physics experiments.

Sadly, just like carbon warming, nothing will get changed until there is a drastic change from assumptions.  That would mean an ice age, or lots more things collapsing.

Linux - 4.18 doesn't boot with amdgpu

4.17.14 is finally working quite well.  Only very heavy use on Chrome is causing it to freeze.  4.18 can't get the frame buffer up.  It worked on earlier versions, but the last few have been bad.

Once again, Atlantic current on the nose

Once again we court disaster.  I've never seen it go below.  It usually drifts up again, on its own schedule.  I generally think that when it goes below the nose we freeze up North.  Probably a worse thing than Saudi Arabia dumping all its assets at a loss. 

In a few weeks, it will probably turn again.
