Comment Re:Why do we have screen savers? (Score 1) 349

My plasma gets burn-in if I pause my DVD player, let the screen on and go play wit the dog for 10 minutes.
The dark scenes get lighter lines in them.

Okay, if I run the screen repair feature (sliding lines of a white gradient to black) for half an hour or so the issue is gone. But screen burn in is a real issue with most plasma tv's

Do those burns have a rough surface and a lighter flame shape?
Then you may have different problems.
If the LCD has screen burn in of the other kind then it is heavily abused.

I once saw a plasma with "it is now safe to turn of your computer" burned in because it was left in that state for a weekend.

Your freedom to swing your fist wildly about ends at my face.

While I do not approve of the intrusive spying the NSA does there is a good reason to use laws to limit the constitution. You may have the right to bear arms and wear masks, that doesn't mean you should be allowed to walk into a bank with a few friends, all with masks on and AK-47's in your hands.
The world is made of area's of gray. Navigating those grey area's requires a lot of judgement calls. On a government scale you must cross that with incompetence and malice, for both will be present in your workforce. That means the way of the judgement calls is highly flawed.

Ports mean entry points for water and dust, crappy covers or expensive ports.
Phones need to be waterproof IMHO. They get wet during an unexpected rain while commuting by bike, so they better be able to handle water.
Data transfer via IEEE 802.11ac (theoretical 500 Mbit/s) is plenty fast for most cases. It's a phone, not a fileserver.
For DisplayPort: there are a couple of companies quite busy with wireless HDMI. It would require another antenna and an additional chip, but that's where it's going.

Comment Re:terminal velocity on mars (Score 2) 75

That depends on 5 main factors:
air density (depends on altitude)
aerodynamic shape of the object
Frontal surface of the object
Mass of the object
The gravitational acceleration on Mars (approx 4 m/s^2)

If I assume the air pressure of 1% of earth means that the density is also 1% then:
p=0.1225 kg/m3.
If I assume a C of 1 (approximately a man facing the planet, see here for more common C's), an A of 1m^2 and a m of 100kg

Plug all that in a calculator like this one.

Then I get a terminal velocity of 82 m/s (or approx 300 km/u), if you drop down flat.
For earth that is approximately 145 km/h. For 300 you have to go face down (lower C and lower A).

The quiet bloke may have a legitimate reason. His neighbors may be bigoted to the extent that he may not survive the year if he comes out of the closet.
(While that is an effective method to get those bigoted idiots in jail, I would not consider it a valuable one.)

Full disclosure is not always the answer.
