The first paragraph reads: “The City of Tallahassee’s Office of Cross-Connection Control monitors actual or potential backflow via cross connections with non-approved water sources.

I had earlier posted about the SNAFUed boondoggle also known as the Eastern span of the Oakland-San Francisco Bay Bridge (here and here), but the bad news just keeps rolling in. Yesterday it was revealed that the tower supporting the entire self-anchored suspension bridge rests on bolts that are likely to fail, causing the...

I have written before about the amazing saga of the new span for the Oakland-San Francisco Bay Bridge, now 24 years and $6.4 billion in the making...with no end in sight. A full account of its background can be found here. The “signature design” never before built and of dubious seismic stability in one...

The horrendous and calculated, July 20th shootings in Aurora, Colorado, are a great tragedy not just for the victims and their families but for everyone who can clearly see the utter evil of such acts and the helplessness we all feel as a result. However this massacre might have been far less likely for...

The elevated freeway that collapsed during the 1989 Loma Prieta earthquake in Oakland had long been known to be non-seismically-sound. Engineering students at nearby University of California, Berkeley were directed to the structure as a case-study in negative harmonics, and we who drove on it regularly were well familiar with the almost seasickening wavy...

...to realize the metal detector isn’t plugged in? No one knows how long it took for the light to dawn yesterday morning for one TSA agent at New York’s busy JFK International Terminal that his metal detector had been unplugged—apparently for hours: Amazingly, he failed to realize that alert lights never flashed once as...
