I've perpetrated one which I felt crummy about. To set the background, I was a sophomore at college in 1986, and the campus is close to some bad neighborhoods. I had had a very scary incident involving several black people while I was riding through one of those areas. So later I'm standing inside the college gate when three teenage black guys come up and start asking me to let them in. Unfortunately, they had a strong accent (from Florida as it turned out) and I couldn't understand most of what they were saying. So I wasn't letting them in...and they were getting pretty pissed. At any rate pretty soon an older student came by, who understood immediately what they were saying. It turned they were relatives of someone I knew, but the way they pronounced her name I just couldn't get it. No doubt it's also because I was nervous and primed with racist preconceptions (which, as I noted, also had some basis in prior experience). Anyway he let them right in and I felt pretty darn bad about it. You come all the way from Florida to visit your cousin at an Ivy League school, and some white kid thinks you're there to steal stuff. (One irony is that later that same year I did witness a black person steal our neighbors' TV...I was so surprised, just watched him carry it down the stairs and out the gate.) All in all I would say that racism weaves a tangled web of preconceptions that can be reinforced by actual events that also are ultimately arising from racist history.

Well, regular intelligence isn't but so useful in business either. There are so many factors in business success, intelligence is just one, and usually not a very big one.

Record number of investors means dumb money, just like 2000. If you don't know who the greater fool is...it's you

Maybe what we need is a return to the very beginning, namely human curated web catalogs, aka Yahoo

Garageband.com

Silicon Investor

Groovetech

And let's not forget how exciting it was to explore around in the original Yahoo!

Although the web doesn't seem to be thing we all dreamed about anymore, it's still amazing. Remember how hard it used to be to learn about anything? Now it's so easy...but the amount of knowledge itself is oppressive.

Commentator appears to have a layman's understanding of quantum mechanics.

Loved this book when I was college age

I've felt that way for years. OO perhaps makes sense for certain things, mainly things that someone else writes and you use as a library. Using OO more widely leads to very inflexible code, and since specs are not inflexible, the result is disaster.

Haha wrong

Yes! How much time have I wasted chasing some stupid error that "just worked" in perl which C or Java would have blocked at the get go. Just say NO to languages that try to guess what you were probably trying to do.

Changed my mind on OO after seeing how difficult it is for ordinary humans to design objects that can withstand the spec changes that are inevitable in any real project. Bad procedural code is a mess but bad object code can be completely irreparable.

I find the opposite - many websites still don't seem to test properly on chrome.

Well, it was fun while it lasted.

I signed up but I see they're using credit card payment...can this work?

E&M is far from "simple". It contains special relativity, for starters. Also it is incompatible with thermodynamics: solving this problem is why Planck invented quantum mechanics. Also point charges have infinite energy: this problem leads to renormalization theory. Also it introduces gauge invariance, an essential but complex part of all modern theories. And lastly, the mathematics of E&M is a big step up from Newtonian theory.
