Good points. I'll go a little off topic here, but hey it's the internet...
In response to IR Stuff and the threshold of a TTL gate; here is some food for thought when hiring engineers and just engineering education in the US.
1. I have no idea what a TTL gate is, but I'm civil, haha.
2. Engineering education sucks. Period, end of story. It's awful...you could not get worse teachers if you tried. These so called "professors" are just hyper specialized, hyper intelligent, research bots spitting out papers that nobody reads, and nobody uses...except that they percolate into my building codes and make them more complicated. This country hit its peak of infrastructure development in the 30s-50s without any of their research, without SE licenses required for more and more structures, without all this computer software, without 200+ page buildings codes, without, without, without... They wore suits, didn't know how to program computers, knew how to communicate, were practical, and come to think of it, we had a real economy, but that's another tangent...
These "professors" are awful, God-awful at teaching. Oh, and the mathematics and pure science professors are worse. Oh, and the foreign professors who are becoming more prevalent, are even worse. The ones from Eastern Europe usually set new lows...Chinese professors are not good, but also don't care so much about punishing the "stupid" American students.
The "smart" morons in charge of engineering education constantly push more and more crap into the curriculum; meaning that Johny has been bombarded with so much knowledge that he can't do anything well. I know people who still cannot execute a perfect shear and bending moment diagram but are taking pie in the sky theoretical mechanics courses.
3. The only places where engineering education might not suck, are at small engineering schools, i.e. Rose Hulman type places, or maybe a place like West Point. The only difference between Berkeley and Southern Kentucky University (I made that up, don't get offended, Kentucky is a highly developed state with great schools and an economy more dynamic than California's) is that Berkeley students have a higher IQ due to higher entrance standards, and are punished with more work and stress. The education might be better in Kentucky, the difference in pedagogy is certainly minimal and not worth any real salary premium. It's just that the Berkeley product should take more stress and working hours before he/she mentally breaks down.
4. Bottom line; hire based on attitude, references, and appearance. If Johny can figure out the TTL gate threshold, but lives like a slob, is anti-social, can't communicate, acts like a gnome, or maybe just comes off as a know it all a-hole...I'd rather take the dumber kid. The dumber kid is still trainable and will probably not get bored with the work and remain loyal to the company. It doesn't mean there aren't those candidates who have it all, and maybe a TTL gate threshold is a really basic aerospace concept, but just remember, the common denominator for most engineers is a really, really, really poor education.
Finally, my high school teachers, paid half as much as these professors, and putting up with way more b.s., were head, shoulders, hills, and mountains above these so called "professors". I'd fire half of them tomorrow and just tell them to go build themselves a research institute where they can syphon money from the DoD and DoE and NSC in order to research their useless b.s. and then hire folks with real world experience, BS and MS degrees, and have them teach us the basics.
Angry, you bet I am. You would be too when paying 10K+ a semester for a garbage product, not to mention living expenses. That's life...right...
