Most of this problem could be resolved if manufacturers made phones with slide-in, slide-out battery packs. One is charging while one is in use. Very simple system, been around for decades. No high-tech solutions needed.

Of course then they might lose the advantage of monitoring everywhere you go ... or being able to lock you in as a customer for *very* expensive battery replacements ... the only "reasons" I can see for doing the obvious thing of making a phone like a transistor radio or like a freaking flashlight.

That's funny. I'd say you got cheated, then.

Because at the merely-public huge university engineering school I attended, one of the earliest things we learned about was the "resonant frequency" of a bridge could cause it to be destroyed by wind or marching soldiers. Yeah, professors with 30 years tenure used that term, as did all of the physics professors at that same institution. And that people and buildings have resonant frequencies as well (as Tesla showed when he scared his neighbors badly.)

If you're buying Apple hardware, from my experience over 22 years, it's a good idea. -Every- Apple product I bought had one or more -hardware- fails within two years - usually *after* the warranty expired. And Apple's willingness to "overlook" the identical disasters of hundreds of customers is boundless.

Once again we see the hidden disaster which is: creating *your database* in a *proprietary format*.

I learned that over and over until I quit doing it. OS and companies come and go at a fierce rate. A database needs to kept in the only format that is guaranteed to remain universally supported. Anything which doesn't support that is self-serving (not customer-serving) poison. EOL

Interestingly, I just started playing with Rootkit Hunter a couple of weeks back, and it complained when it saw "PermitRootLogin yes".

Since I didn't know that existed, it was either set that way by the very popular distribution I'm using OR (unlikely) by an external force. I'm sure no expert, but allowing login as root via SSH just didn't sound like a good idea. Maybe it's all those 'Security Now' episodes.

The message a college using this is sending you is: go somewhere else. Go somewhere where people's first concern is about you getting an education, where that isn't just ancillary to their "real" mission but where it IS their mission. Where helping you isn't a time-limited inconvenience, but the core mission of the institution.

I've spent a lifetime working with machine learning, and the very idea that any machine today can even begin to comprehend natural language is pathetically laughable. You'll be expected to adapt your responses to the extremely low common denominator the machine represents, and the result is you'll be conditioned to retard your own thinking processes. THEY can't pay YOU enough to settle for such nonsense.

Would Galileo have had more success with his telescope if he had been Christopher Hitchens?

No, but he'd have had more telescope time if he hadn't had to spend years battling the Church's entrenched idiocracy. You'd make a fine apologist, my friend, consider working for the Discovery Institute lately?

Not a "third belt" at all. A temporary "third concentration" within the Van Allen belt, yes. The lower concentration is blamed on cosmic ray neutron=>proton interactions, the upper concentration to atmospheric and solar electrons. The belt was already known to consist of some concentration of energetic particles from 250-20,000 km. Naturally that varies at various levels as incoming particles are pulled into the magnetosphere.

Comment: Who cares? (Score 1) 209

"Research by Harvard professor..." Who cares where he does his armchair science from? The real research is being done by building windmills around the world. Has there been a documented lessening of windflow anywhere as a result?

"as wind farms grow larger, they start to interact"
So don't build them too close together?

"If we were to cover the entire Earth with wind farms, he notes, "the system could potentially generate enormous amounts of power, well in excess of 100 terawatts, but at that point my guess, based on our climate modeling, is..."

My guess.
Guess we'll just have to get to 100 terawatts, then, and then we can test his 'guess' in the real world.

Etiquette is for those with no breeding; fashion for those with no taste.
