This is an issue that has been much debated, and to the best of my knowledge not yet firmly decided.
No, it is not an issue that has been debated. The practical aerodynamics of airfoils is very well settled.
If you have paid attention carefully when flying you may have noticed that a plane does not fly completely flat most of the time. There is a small angle between the planes wings and the direction of travel. Because air tends to follow the surface of the wing (sometimes called the Coanda effect) this means that the air gets deflected downwards by the wing. If the air accelerates down then by Newton's laws there is an equal and opposite force upwards on the plane generating lift so it can then fly.
1) This has little to do with the Coanda effect.
2) While there is momentum imparted onto the lower surface of a wing at a positive angle of attack, pressure distributions along the surfaces dominate the behavior of the airfoil. Air is slowing down when it follows the lower surface of a flat plate, and speeds up along the top, which gives (gasp) a pressure differential.
Thirding this. I love my MSI Wind nettop (with the dual core atom), great investment as an ubuntu server. Doesn't have onboard RAID, but setting up a software raid is plenty easy. Super tiny, super low power.
Don't start with Arch or LFS, start with Ubuntu. As you use it, realize the speed doesn't go away due to a website you've hit, or a longstanding problem with defragging. Think about how no website is dangerous anymore, and how loading programs happens with a click, no dependencies, no BS...and you'll agree with me: if it can't be done in Linux, don't do it.
Amen to that. And/or the converse: any task which can only be done in Windows, isn't worth doing. I've been Microsoft-free for over a decade now and have loved every minute of it.
I can honestly say I've never been exposed to that level of fanatical fanboyism, even on slashdot.
the dialog in question is not tricky, hidden, or in any way misleading
is not at all innocuous. Something called "iPhone Configuration Utility" which is checked by default, although unnecessary to actually "configure an iphone", is pretty much the definition of misleading. Packaging a webserver with this "iPhone Configuration Utility" and not explicitly stating, or giving an option, that it includes f'ing Apache, is pretty much the definition of hidden.
This is bloatware, plain and simple.
When you state that "Apple's motives are always clear... the goal of making things easier/better/safer for the end user", you're clearly implying that their competitor's motives *aren't* clear. Like somehow Windows Update is some nefarious tool to push bloatware onto unsuspecting users.
The slashdot population never ceases to amaze; the same people that will bemoan windows including IE are willing to make excuses for a software travesty like iTunes.
So every decision MS makes is because they're evil, and every decision Apple makes is out of the good of their hearts? Good lord do they ever have great PR.
Why an F'ing music syncing application needs something like 8 persistently running services is absolutely beyond me.
Why I need "an F'ing music syncing application" to transfer audio files onto a flash device via USB, when every other similar device allows me to just drag some files onto the drive in explorer, is absolutely beyond me.
Sounds to me like they're fixing the number one problem in FOSS. Lack of direction and management is what leaves open source software so unpolished compared to it's corporate "competition".
"governance structure that concentrates authority at the top"
I realize that very well. It's hard to explain rocket size in terms of delta-V (velocity change, not the rocket model) to a layman, so I settled with expressing that LEO is nowhere close to moon orbit insertion.
Or as Heinlein put it (roughly): "get to LEO and you're halfway to anywhere in the Solar System".
no, you're not.
and necessary fuel weight grows exponentially with payload, and necessary delta-V.
A Mars colony would seem to me that it would be more likely to work if it was tried first on the Moon. With supply lines being so much shorter, eventually a fairly decent size colony could be built, in a much shorter time frame. It really seems far less complicated than building the ISS.
It seems that way, if you ignore reality. ISS distance: 220 miles. Moon distance: 238,000. The difference in fuel needed alone is hardly in the same ballpark.

In other words, you are an ignorant fuck. Yes, I am an engineer and you're not.

Someone paid these researchers to develop the software. Ignoring that cost is pretty misleading.

Well the playback in Linux might be a little jerky.
Oh definitely. We should all be running (ancient obscure OS that makes me sound cool) still, and never upgrade.

Unbelievable. How many free passes does Apple get before you start to question their infallibility?
A lot. Next.

I'm sure you would hear some wealthy people tell you that it mostly is their money...
And they'd be correct. The top 1% is paying 37% of the nation's total income tax, while making only 19% of the total income.
So let the rich people fund it with their own money, not force everyone through government coercion.
Great idea. Maybe let the rich people actually keep their own money, instead of taxing them upwards of 50%?
Compared to Windows, Linux administration is a breeze. A Linux system ran by a normal user who doesn't screw around as root, will remain stable.
How exactly does one administer Linux *without* "screwing around as root"?
First day on /.? You must've missed the FAQ detailing how Bill Gates invented AIDS.
MS has the marketing and the 5 clicks that lets a "manager / phb" install MS server and call themselves admins
I am constantly amused at how Linux apologists can actually make ease-of-use sound like a bad thing.

Actually it was a troll. I was looking for "well, Windows has had it for years."
That's a fantastic feature... I'm trying to think of another OS that has that.

Younger astronauts mean a greater ROI. I'm sure there's plenty of well-qualified people willing to be known as a pioneer for the rest of history.
