Its not clear from the write up why no one noticed the lightning but thinking about it I realized that "99.9%" of lightning strikes caused "no" problem. The data got messed up but it was caught by the program and the data was sent again. So only "once in thousand times" did the lightning strike hit the narrow time window that caused corrupted data to be recieved. A crash would occurred only once every month or so which made the correlation harder and probably it happened at night!
This made me wonder how I figured it out(:|). Maybe a summer on a lookout in Idaho's primitive area helped. More recently I got envolved in analyzing the effect of lightning striking a satelite fueling facility and currents in a grounding line going through the satelite and causing some damage.
I think part of that depends on your discipline, Ann. As a test engineer it is critical to have a high awareness of both hardware and software operation...if you only think about one or the other you won't get very far. However, most folks do seem to be a bit better at one than the other - I guess that might be a function of how our brain works...while my husband and I do both hardware and software - he has more hardware expertise and I have more software expertise so when we do projects together he typically does the HW and I do the SW. So of course whenever there is a problem - it must be the HW :)
I find it mind-boggling that the engineers couldn't make the connection, and so many times. But sad to say, I have known many software people who don't seem, uh, connected to the physical world and how it works.
It's unbelievable that for 3 months the Computer Programming guys never noticed that the computers crashed only during thunderstorms. Surely, they should have. It's funny how technology makes us forget about nature. This proves how much the two are largely related.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
