This is nothing new. My son is now 29 and at school was in this situation. He isn't even a techie, he's an artie, but had computer access at home from birth. I think the only answer is to have technical professionals teaching. At school (in the 60's) I learned metalwork and woodwork, not from graduates, but from tradesmen who been taught teaching skills.

Actually the audible buzz from the speakers of most audio equipment is 100/120Hz due to full wave rectification which doubles the frequency. There are families of harmonics too.
A sound restoration area I'm involved with uses the mains hum present on old master recordings to determine the optimal playback speed.

". . . which is exactly what Muslims are trying to do to us today, in OUR countries!"
There is some truth in this, though they're just the 3rd Abrahamic religion to try it. They won't touch us Pagans!

"When the USA was trying to form a liberal democracy Iraq and Afghanistan, what happened? A bunch of insurgencies with attacks with homemade bombs on the troops."
I think you mean: When the US (and allies) were trying to impose THEIR idea of how to live. Whilst liberal democracy works quite well in in the west, that doesn't mean it can be transplanted into any society successfully. Many of those who have lived under dictatorships or tribally have no concept of how to integrate with it so it is hardly surprising that even ordinary folk, let alone those with a stake, will rebel.

They're just cunts.

I've used OS X since it's release, this is the first of the many published vulnerabilities that actually causes me concern. From a security perspective Spotlight is unusable on Yosemite machines until this is fixed. Thank goodness my main machines are still on 10.9.

"Well let's see... the IRA/English's battle over Northern Ireland (largely drawn across Catholic/Protestant religious lines) cease fire was just over 20 years ago. And the final peace accord was only 17 years ago. That marked the end of 30 years of assassinations, murders, bombings, and attacks all of which were surrounded by religious fervour."
Wrong. The conflict was about differing traditions and governance. The fact that the 2 groups had differing flavours of Christianity was a detail.

Nevertheless it's slightly more credible than N.K. having done it.

There is something disturbing about your selective use of apostrophes. Which part of me isn't a monkey? - Said the Eskimo...

Isn't this the company who gave Seagate a a hard time over the reliability that they had WITH THIER SAMPLE? I have no reliability issues with Seagate compared with several other suppliers (WITH MY SAMPLE).

I go once got lost in an Icelandic forest, but then I stood up.

Thanks, I'd never considered "remove(ing) the dimensions". It helps a lot!

They probably pass on the chaff and keep the juicy ones. But let me ask you this: If you had their brief, would you do anything different?

AC is correct. Jamming GPS (or equivalent other satellite system) is trivial and has been done. It's a major system weakness.

A decade ago I would have believed this as gospel, now I'm not sure. It's difficult to believe the US voice any more.
